Canonical Gymnasium Migration Status

This document tracks the migration progress from legacy Gymnasium source trees into the DE-level canonical layer.

Assumption for this document:

"existing repos" means the legacy curriculum source trees that are or recently were operationally relevant inside this monorepo.
The main tracked trees in scope today are:
curricula/DE/HE/Kultusministerium/Gymnasiale_Oberstufe
curricula/DE/HE/Kultusministerium/Gymnasium_9_Mittelstufe
curricula/DE/BY/Gymnasium

This document is intentionally stricter than the rollout plan:

100% means the old legacy source trees are no longer needed for runtime/operations and can be deleted from the active repo.

Progress model

The existing rollout states remain the operational backbone:

legacy_frozen
subtree_adopted
cutover_ready
legacy_view_retained

For program tracking, we assign a score to each tracked migration unit:

State	Score	Meaning
`legacy_frozen`	0%	Legacy subtree is still authoritative source only
`subtree_adopted`	50%	Canonical subtree + mappings exist, but operational switch is not yet low-risk
`cutover_ready`	75%	Runtime projection and learner cutover are good enough for operational migration
`legacy_view_retained`	90%	Canonical is preferred, legacy still exists only as compatibility view
`legacy_deleted`	100%	Legacy source tree is no longer needed and has been removed from the active repo

Important interpretation:

legacy_view_retained is deliberately not 100%.
We only call the program 100% when the old trees are actually removable.

Completion-track headline score

The historical rollout score above is still useful for explaining how much canonical structure exists. It is not the best top-line number for the final stretch, because late-stage work is dominated by retiring the remaining legacy trees rather than by adding new adopted subtrees.

For the close-out phase, we therefore also track one explicit overall completion-to-finish score:

completion-track score = average of the tracked legacy-tree delete-gate scores

Formula:

completion-track score
  = (gate score of each tracked legacy tree) / number of tracked legacy trees

Interpretation:

this is the primary top-line percentage for the final migration stretch
it starts to matter once at least one tracked legacy tree has actually been retired
unlike the older rollout score, it is tied directly to the remaining delete-handoff work
from here on, progress updates should prefer this number as the main "how close are we?" headline

Reported headline 2026-03-18

Current reported migration status:

100%

Why this is the right number right now:

3 of the 3 tracked legacy trees are already deleted from the active repo
all old legacy-tree runtime paths were removed, including curricula/DE/BY/Gymnasium
the current delete-handoff boundary is now enforced via DE-level retained-asset, mapping, and provenance registries instead
the close-out headline is now capped correctly because all tracked legacy trees are retired from the active repo

Update 2026-04-10

What changed:

canonical Physics reached M1 Hessen+Bavaria hardened parity inside the DE-level canonical layer
the canonical Physics landscape now carries:
9 programUnits
19 goalPlacements
5 competencyCatalog entries
17 goals with reviewed competencyRefs
Physics composition views now include not only the 5 DE-wide baseline files, but also 8 explicit reviewed DE-HE / DE-BY scope views
active Physics mapping lanes and canonical identifiers no longer present the subject as a live pilot
active Physics provenance and applicability exceptions now live in the shared DE-level registries instead of staying inline in the canonical graph JSON

Validation used:

cd app && npm run validate:graph
cd app && npm run validate:view-filters
cd app && npm run validate:composition-views
cd backend && ./gradlew test --tests 'com.skillpilot.backend.service.CompositionViewServiceTest'
cd backend && ./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'

Validation result:

validate:graph: 593 landscape(s) passed validation.
validate:view-filters: 0 error(s), 1382 warning(s), 337 accepted warning(s)
validate:composition-views: 86 composition view(s) passed validation.
the Physics backend parity bundle passed with the new registry-backed and state-scoped view assertions

Interpretation:

this does not change the migration delete-handoff headline, which remains 100%
it does close the remaining canonical Physics hardening gap for the reviewed Hessen+Bavaria corridor
the next Physics work is no longer basic parity cleanup; it is repeatable M2 onboarding for additional Bundeslaender

2026-04-10: NRW upper-secondary Physics completes the first M2 source-lane activation

What changed:

the first NRW upper-secondary Physics source snapshot now exists at:
curricula/DE/Gymnasium/input/NW/upper-secondary/source-json/DE_NRW_S_GYM_2_PHYSIK.de.json.snapshot
the shared DE-level provenance registries now also carry this NRW Physics lane:
curricula/DE/Gymnasium/provenance/source-landscape-registry.json
curricula/DE/Gymnasium/provenance/source-goal-membership-registry.json
curricula/DE/Gymnasium/provenance/source-goal-closure-registry.json
the reserved repository-backed mapping scaffold now exists at:
curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/nrw_physics_upper_secondary_to_canonical_physics.json
the first active NRW Physics lane is intentionally narrow and source-led:
one shared orientation anchor
one Einfuehrungsphasen entry on periodische Vorgaenge, Kreisbewegung, Gravitation, and physikalische Weltbilder
two Grundkurs anchors on Quantenobjekte and Klassische Wellen und Teilchen in Feldern
one Leistungskurs anchor on Quantenphysik plus Atom- und Kernphysik

Validation used:

cd backend && ./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'

Interpretation:

Physics now has a real third-state DE-level source lane beyond Hessen and Bayern
this is still a source-lane activation, not yet a reviewed canonical corridor mapping
the next clean NRW Physics move is the first reviewed upper-secondary mapping corridor on top of this active source snapshot

2026-04-10: NRW upper-secondary Physics opens the first reviewed entry corridor

What changed:

the NRW Physics mapping lane now carries 5 reviewed mappings at:
curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/nrw_physics_upper_secondary_to_canonical_physics.json
the first reviewed cut stays intentionally narrow:
shared source root -> canonical Physics root (partial)
shared orientation anchor -> shared canonical motivation leaf (exact)
NRW E-phase entry cluster -> shared canonical E-phase mechanics surface (partial)
Periodische Vorgaenge in alltaeglichen Situationen untersuchen -> Harmonische Schwingung verstehen (partial)
Kreisbewegung, Gravitation und physikalische Weltbilder modellieren -> integrated canonical gravitation/worldview task surface (partial)
the NRW Physics onboarding note and mapping-lane README now reflect that the lane has moved beyond pure scaffold state

Validation used:

cd backend && ./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
cd app && npm run validate:view-filters

Interpretation:

NRW Physics has now crossed from pure source-lane activation into the first reviewed canonical bridge set
the reviewed corridor is still conservative and does not yet claim a full NRW cutover tree
the next clean NRW Physics move after this first corridor was the second reviewed Quantenobjekte corridor documented below

2026-04-10: NRW upper-secondary Physics adds a second reviewed `Quantenobjekte` corridor

What changed:

the NRW Physics mapping lane now carries 8 reviewed mappings at:
curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/nrw_physics_upper_secondary_to_canonical_physics.json
the new second corridor adds three conservative partial bridges onto the canonical Q3 duality surface:
NRW GK Quantenobjekte -> canonical Welle-Teilchen-Dualismus
Photonen und Elektronen als Quantenobjekte beschreiben -> canonical Welle-Teilchen-Dualismus
Die Bedeutung von Modellen an Photon und Elektron reflektieren -> canonical Welle-Teilchen-Dualismus
the onboarding note, mapping-lane README, and repository-backed fixture test now reflect the widened NRW Physics bridge set

Validation used:

cd backend && ./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
cd app && npm run validate:view-filters

Interpretation:

NRW Physics now has one reviewed E-phase corridor plus one reviewed GK Quantenobjekte corridor
the canonical Q4 cluster Quantenobjekte remains intentionally unused for this NRW GK bridge because it is didactically deeper than the imported NRW surface
the next clean NRW Physics move after this second corridor was the split between Wellen and Felder documented below

2026-04-10: NRW upper-secondary Physics splits the reviewed `Wellen` / `Felder` corridor

What changed:

the NRW Physics mapping lane now carries 10 reviewed mappings at:
curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/nrw_physics_upper_secondary_to_canonical_physics.json
the new split corridor adds two conservative partial bridges:
Klassische Wellenphaenomene an Licht beschreiben -> canonical Q3 Elektromagnetische Wellen
Geladene Teilchen in homogenen E- und B-Feldern untersuchen -> canonical Q1 Elektrisches und magnetisches Feld
the mixed NRW parent Klassische Wellen und Teilchen in Feldern intentionally remains unmapped on parent level because the canonical Physics graph separates the didactic surface into reviewed Q3 light-wave and Q1 field branches instead of one shared mixed parent node
the onboarding note, mapping-lane README, and repository-backed fixture test now reflect the widened NRW Physics bridge set

Validation used:

cd backend && ./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
cd app && npm run validate:view-filters

Interpretation:

NRW Physics now has reviewed entry bridges on the shared motivation/E-phase surface, on GK Quantenobjekte, and on the first split GK Wellen / Felder surface
this step keeps the canonical separation between Q3 light-wave topics and Q1 field dynamics explicit instead of inventing a synthetic mixed canonical parent
the next clean NRW Physics move after this split corridor was the first reviewed LK bridge documented below

2026-04-10: NRW upper-secondary Physics opens the first reviewed LK corridor

What changed:

the NRW Physics mapping lane now carries 13 reviewed mappings at:
curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/nrw_physics_upper_secondary_to_canonical_physics.json
the first LK corridor adds three conservative partial bridges:
NRW LK Quantenphysik sowie Atom- und Kernphysik -> canonical Q4 Struktur von Materie, Raum und Zeit
Quantenphysik als Weiterentwicklung des physikalischen Weltbilds deuten -> canonical Q4 Quantenobjekte
Aufbau der Materie sowie ionisierende Strahlung und Kernprozesse modellieren -> canonical Q4 Kernphysik
the onboarding note, mapping-lane README, and repository-backed fixture test now reflect the widened NRW Physics bridge set

Validation used:

cd backend && ./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
cd app && npm run validate:view-filters

Interpretation:

NRW Physics now has one reviewed LK entry corridor in addition to the reviewed E-phase and GK corridors
the LK bridge intentionally stays on canonical cluster level because the imported NRW LK atoms are still broader than the currently reviewed canonical Q4 atomic surfaces
the next clean NRW Physics move is now a narrower LK split inside Quantenobjekte or Kernphysik, most likely around radioactivity / nuclear processes or around the Q4 measurement / world-view residue

2026-04-10: NRW upper-secondary Physics narrows the LK `Kernphysik` residue

What changed:

the NRW Physics mapping lane now carries 15 reviewed mappings at:
curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/nrw_physics_upper_secondary_to_canonical_physics.json
the NRW upper-secondary Physics source snapshot was widened in place so the retained LK residue Aufbau der Materie sowie ionisierende Strahlung und Kernprozesse modellieren is now a source cluster with three child atoms:
Aufbau der Materie im Kleinen modellieren
Ionisierende Strahlung und radioaktive Zerfaelle modellieren
Strahlungsrisiken und Kernprozesse fachlich beurteilen
the narrower LK residue now adds two conservative partial bridges:
Ionisierende Strahlung und radioaktive Zerfaelle modellieren -> canonical Q4 Radioaktive Strahlung und Wirkungen
Strahlungsrisiken und Kernprozesse fachlich beurteilen -> canonical Q4 Beurteilung von Strahlungsrisiken und Kernenergie
the retained source cluster Aufbau der Materie sowie ionisierende Strahlung und Kernprozesse modellieren stays mapped to canonical Q4 Kernphysik
the parallel new NRW child Aufbau der Materie im Kleinen modellieren intentionally remains unmapped for now because the current canonical Q4 surface does not yet expose a reviewed one-to-one target without overclaiming toward a more specific elementarteilchen surface
the source membership and atomic-closure registries now reflect the widened NRW Physics snapshot and the narrower LK residue children
the onboarding note, mapping-lane README, and repository-backed fixture test now reflect the widened NRW Physics bridge set

Validation used:

cd backend && ./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
cd app && npm run validate:view-filters

Interpretation:

NRW Physics now has its first reviewed LK residue split inside the canonical Q4 Kernphysik surface
this still is not a full NRW Q4 cutover: the new child bridges stay conservative and one LK matter child remains source-led and intentionally unmapped
the next clean NRW Physics move is now either a further reviewed split of the new radiation child toward Zerfallsgesetze anwenden or a reviewed canonical target for the still unmapped LK matter child

2026-04-10: NRW upper-secondary Physics splits the LK radiation residue toward `Zerfallsgesetze`

What changed:

the NRW Physics mapping lane now carries 16 reviewed mappings at:
curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/nrw_physics_upper_secondary_to_canonical_physics.json
the retained NRW LK radiation child Ionisierende Strahlung und radioaktive Zerfaelle modellieren was widened in place into a source cluster with two narrower child atoms:
Ionisierende Strahlung nachweisen und Wirkungen beschreiben
Radioaktive Zerfaelle und Kernumwandlungen qualitativ beschreiben
the earlier direct bridge from the broad NRW radiation child onto canonical Radioaktive Strahlung und Wirkungen is replaced by two narrower conservative partial bridges:
Ionisierende Strahlung nachweisen und Wirkungen beschreiben -> canonical Q4 Radioaktive Strahlung und Wirkungen
Radioaktive Zerfaelle und Kernumwandlungen qualitativ beschreiben -> canonical Q4 Zerfallsgesetze anwenden
the retained NRW LK residue cluster Aufbau der Materie sowie ionisierende Strahlung und Kernprozesse modellieren stays mapped to canonical Q4 Kernphysik
the sibling NRW LK child Strahlungsrisiken und Kernprozesse fachlich beurteilen stays mapped to canonical Q4 Beurteilung von Strahlungsrisiken und Kernenergie
the parallel NRW LK child Aufbau der Materie im Kleinen modellieren still remains intentionally unmapped
the source membership and atomic-closure registries now reflect the widened NRW Physics snapshot and the narrower radiation residue children
the onboarding note, mapping-lane README, M2 shortlist, and repository-backed fixture test now reflect the widened NRW Physics bridge set

Validation used:

cd backend && ./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
cd app && npm run validate:view-filters

Interpretation:

NRW Physics now has a first reviewed NRW access path not only to canonical Radioaktive Strahlung und Wirkungen, but also to Zerfallsgesetze anwenden
this is still conservative: both new NRW bridges remain partial, and the broader risk/judgement child plus the matter child still mark the remaining LK residue
the next clean NRW Physics move is now either a reviewed split below the current risk/judgement child or a reviewed canonical target for the still unmapped LK matter child

2026-04-10: NRW upper-secondary Physics splits the LK judgement residue toward `Strahlungsrisiken` and `Kernenergieoptionen`

What changed:

the NRW Physics mapping lane now carries 17 reviewed mappings at:
curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/nrw_physics_upper_secondary_to_canonical_physics.json
the retained NRW LK judgement child Strahlungsrisiken und Kernprozesse fachlich beurteilen was widened in place into a source cluster with two narrower child atoms:
Strahlungsrisiken mit physikalischen Groessen beurteilen
Kernenergieoptionen mit physikalischen Kriterien bewerten
the earlier direct bridge from the broad NRW judgement child onto canonical Beurteilung von Strahlungsrisiken und Kernenergie is replaced by two narrower conservative partial bridges:
Strahlungsrisiken mit physikalischen Groessen beurteilen -> canonical Q4 Strahlungsrisiken mit physikalischen Größen beurteilen
Kernenergieoptionen mit physikalischen Kriterien bewerten -> canonical Q4 Kernenergieoptionen mit physikalischen Kriterien bewerten
the retained NRW LK residue cluster Aufbau der Materie sowie ionisierende Strahlung und Kernprozesse modellieren stays mapped to canonical Q4 Kernphysik
the sibling NRW LK matter child Aufbau der Materie im Kleinen modellieren still remains intentionally unmapped
the source membership and atomic-closure registries now reflect the widened NRW Physics snapshot and the narrower judgement residue children
the onboarding note, mapping-lane README, M2 shortlist, and repository-backed fixture test now reflect the widened NRW Physics bridge set

Validation used:

cd backend && ./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
cd app && npm run validate:view-filters

Interpretation:

NRW Physics now has first reviewed NRW access paths not only to the canonical Q4 context cluster, but also to its two narrower judgement leaves
this is still conservative: both new NRW bridges remain partial, and the LK matter child still marks the remaining source-led residue
the next clean NRW Physics move is now a reviewed canonical target for the still unmapped LK matter child, or a further source split inside that matter wording if no reviewed one-to-one target exists yet

2026-04-10: NRW upper-secondary Physics splits the LK matter residue without claiming a new canonical bridge

What changed:

the NRW Physics mapping lane still carries 17 reviewed mappings at:
curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/nrw_physics_upper_secondary_to_canonical_physics.json
the retained NRW LK matter child Aufbau der Materie im Kleinen modellieren was widened in place into a source cluster with two narrower child atoms:
Elementare Bestandteile der Materie mit Strukturmodellen ordnen
Kernaufbau und Bindungen in einfachen Modellen beschreiben
no new reviewed canonical bridge is claimed yet for these two new matter children
the retained NRW LK residue cluster Aufbau der Materie sowie ionisierende Strahlung und Kernprozesse modellieren stays mapped to canonical Q4 Kernphysik
the source membership and atomic-closure registries now reflect the widened NRW Physics snapshot and the narrower matter residue children
the onboarding note, mapping-lane README, and M2 shortlist now reflect the widened source split without changing the reviewed mapping count

Validation used:

cd backend && ./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
cd app && npm run validate:view-filters

Interpretation:

the NRW Physics LK matter wording is now materially easier to review against the canonical Q4 matter surface because elementare Bestandteile and Kernaufbau/Bindungen are no longer bundled into one broad source atom
the canonical DE Physics graph still does not yet offer a reviewed one-to-one target for either child without overclaiming into explicit Standardmodell or stronger binding-energy detail
the next clean NRW Physics move is now a decision on whether Elementare Bestandteile der Materie mit Strukturmodellen ordnen justifies a conservative partial bridge toward a narrow Standardmodell surface, or whether the matter lane should stay source-led pending further canonical refinement

2026-04-10: NRW upper-secondary Physics opens a first matter bridge toward `Elementarteilchen und Standardmodell`

What changed:

the NRW Physics mapping lane now carries 18 reviewed mappings at:
curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/nrw_physics_upper_secondary_to_canonical_physics.json
the new NRW LK matter child Elementare Bestandteile der Materie mit Strukturmodellen ordnen now maps conservatively as partial onto the canonical Q4 cluster Elementarteilchen und Standardmodell
this is intentionally a cluster-level bridge, not yet a narrower claim onto Standardmodell: Teilchenfamilien or Hadronen aus Quarks deuten
the sibling NRW LK matter child Kernaufbau und Bindungen in einfachen Modellen beschreiben remains intentionally unmapped
the onboarding note, mapping-lane README, and repository-backed fixture test now reflect the widened NRW Physics bridge set

Validation used:

cd backend && ./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
cd app && npm run validate:view-filters

Interpretation:

NRW Physics now has a first reviewed access path into the canonical Q4 matter / Standardmodell surface without overclaiming the sharper Hessen-authored atomic detail
this remains conservative: the new bridge is partial and intentionally stops at the cluster level
the next clean NRW Physics move is now to decide whether Kernaufbau und Bindungen in einfachen Modellen beschreiben justifies a reviewed canonical target, or whether the matter lane should stay source-led beyond this first Standardmodell access path

2026-04-10: NRW upper-secondary Physics splits the remaining LK matter residue into `Kernaufbau` and `Bindungen/Modellgrenzen`

What changed:

the NRW Physics mapping lane still carries 18 reviewed mappings at:
curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/nrw_physics_upper_secondary_to_canonical_physics.json
the retained NRW LK matter subcluster Kernaufbau und Bindungen in einfachen Modellen beschreiben was widened in place into two narrower child atoms:
Kernaufbau in einfachen Modellen beschreiben
Einfache Bindungen in Materiemodellen beschreiben und Modellgrenzen einordnen
no new reviewed canonical bridge is claimed for those two narrower children
the retained source snapshot, source membership registry, and source atomic-closure registry now reflect 25 NRW Physics source goals instead of 23
the onboarding note, mapping-lane README, and M2 shortlist now reflect the narrower retained matter residue without changing the reviewed mapping count

Validation used:

cd backend && ./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
cd app && npm run validate:view-filters

Interpretation:

the remaining NRW LK matter residue is now easier to review against the canonical Q4 nuclear-matter surface because Kernaufbau and Bindungen/Modellgrenzen are no longer bundled into one retained source atom
this stays intentionally source-led: the current canonical Physics graph still does not expose a reviewed one-to-one target for either new child without overclaiming toward stronger binding-energy, reaction, or particle-physics statements
the next clean NRW Physics move is now to decide whether Kernaufbau in einfachen Modellen beschreiben justifies a conservative reviewed target, or whether the matter lane should remain source-led until the canonical Q4 matter surface is refined further

2026-04-10: NRW upper-secondary Physics opens a structural matter bridge onto the canonical atom model surface

What changed:

the NRW Physics mapping lane now carries 19 reviewed mappings at:
curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/nrw_physics_upper_secondary_to_canonical_physics.json
the narrowed NRW LK matter child Kernaufbau in einfachen Modellen beschreiben now maps conservatively as partial onto the existing canonical atom-structure leaf Kern und Hülle des Atoms qualitativ beschreiben
this is intentionally a cross-stage structural bridge onto an already reviewed canonical atom, not a sharper Q4 claim onto Bindungsenergie und Massendefekt, Potenzialtopfmodell für Kerne, or Kernreaktionen und Kernmodelle
the sibling NRW LK matter child Einfache Bindungen in Materiemodellen beschreiben und Modellgrenzen einordnen remains intentionally unmapped
the onboarding note, mapping-lane README, M2 shortlist, and repository-backed fixture test now reflect the widened NRW Physics bridge set

Validation used:

cd backend && ./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
cd app && npm run validate:view-filters

Interpretation:

NRW Physics now has a second reviewed access path on the LK matter residue: one bridge into the broad Q4 Elementarteilchen surface and one bridge into the already shared canonical atom-structure surface
this remains conservative in fachlicher Hinsicht, but operationally it adds one new active APV-202 for the canonical atom-structure leaf because the NRW reach on that target is now backed explicitly by a reviewed partial mapping
the next clean NRW Physics move is now to decide whether the remaining Bindungen/Modellgrenzen residue justifies a reviewed canonical target, or whether the matter lane should stop here for now

2026-04-10: NRW upper-secondary Physics splits the last LK matter residue into `Bindungen` and `Modellgrenzen`

What changed:

the NRW Physics mapping lane still carries 19 reviewed mappings at:
curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/nrw_physics_upper_secondary_to_canonical_physics.json
the retained NRW LK matter child cluster Einfache Bindungen in Materiemodellen beschreiben und Modellgrenzen einordnen was widened in place into two narrower child atoms:
Einfache Bindungen in Materiemodellen beschreiben
Modellgrenzen einfacher Materiemodelle fachlich einordnen
no new reviewed canonical bridge is claimed for those two narrower children
the retained source snapshot, source membership registry, and source atomic-closure registry now reflect 27 NRW Physics source goals instead of 25
the onboarding note, mapping-lane README, and M2 shortlist now reflect the narrower retained matter residue without changing the reviewed mapping count

Validation used:

cd backend && ./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
cd app && npm run validate:view-filters

Interpretation:

the remaining NRW LK matter residue is now narrower to review against the canonical Q4 matter surface because Bindungen and Modellgrenzen no longer share one retained source atom
this still stays intentionally source-led: the current canonical Physics graph does not yet expose reviewed one-to-one targets for either new child without overclaiming toward stronger binding-energy, reaction, or particle-physics statements
the next clean NRW Physics move is now to decide whether Einfache Bindungen in Materiemodellen beschreiben justifies a conservative reviewed target, or whether the last two matter residuals should remain source-led for now

2026-04-10: NRW upper-secondary Physics keeps the last LK matter children source-led after explicit target review

What changed:

the NRW Physics mapping lane still carries 19 reviewed mappings at:
curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/nrw_physics_upper_secondary_to_canonical_physics.json
the narrower NRW LK matter child Einfache Bindungen in Materiemodellen beschreiben was reviewed explicitly against the current closest canonical candidates:
Bindungsenergie und Massendefekt
Potenzialtopfmodell für Kerne
Fundamentale Wechselwirkungen
no new reviewed canonical bridge is claimed, because those current candidates all overclaim the NRW source wording in different directions
the onboarding note, mapping-lane README, and M2 shortlist now record this reviewed stop condition instead of keeping the lane in an implicit "maybe next" state

Validation used:

git diff --check

Interpretation:

Bindungsenergie und Massendefekt is too sharp because it already includes mass-defect explanation plus simple reaction-energy calculation
Potenzialtopfmodell für Kerne is too specific because it presupposes the narrower binding-energy / nuclear-potential framing
Fundamentale Wechselwirkungen is too broad because it sits inside the later Standardmodell / interactions package and asks for the four interactions across atomic, nuclear, and cosmic processes
the next clean NRW Physics move is therefore no longer another mapping on this matter residue, but either a new narrow canonical binding-model surface or a shift to another still-open NRW Physics corridor

2026-04-10: Physics gets its first bundesland rollout tracker after the NRW activation

What changed:

the first Physics rollout tracker now exists at:
curricula/DE/Gymnasium/provenance/physics-bundesland-rollout-tracker.json
the first generated Physics bundesland quick view now exists at:
docs/dev/canonical-gymnasium-physics-bundeslaender-status.md
a repository-backed renderer now exists at:
scripts/render_canonical_physics_bundesland_status.py
the tracker currently covers the active canonical Physics states DE-HE, DE-BY, and DE-NW
the parity plan and the M2 shortlist now no longer describe Physics as a two-state-only surface

Validation used:

python3 scripts/render_canonical_physics_bundesland_status.py
git diff --check

Interpretation:

this is a rollout-discipline step, not a new canonical Physics mapping
it closes one real parity gap versus mathematics: Physics now has a machine-readable state tracker plus a rendered quick-view status artifact
the next clean move can now be chosen against a visible three-state rollout surface instead of relying only on the narrower NRW lane log

2026-04-10: NRW Physics gets its first committed upper-secondary applicability cut

What changed:

the canonical Physics landscape has now been realigned to the current compiled applicability state:
curricula/DE/Gymnasium/canonical/DE_DEU_S_GYM_CANONICAL_PHYSIK.de.json
this first committed NRW upper-secondary applicability cut now persists DE-NW on seven shared canonical targets reached by the reviewed NRW lane:
Harmonische Schwingung verstehen
Gravitation und Weltbilder in GK-Aufgaben verknüpfen
Radioaktive Strahlung und Wirkungen
Zerfallsgesetze anwenden
Strahlungsrisiken mit physikalischen Größen beurteilen
Kernenergieoptionen mit physikalischen Kriterien bewerten
Kern und Hülle des Atoms qualitativ beschreiben
the accepted-warning registry now records the seven NRW-specific Physics APV-202 findings explicitly:
docs/qa-ci/applicability-accepted-warnings.json
the NRW onboarding note, lane README, tracker note, and Physics M2 shortlist now reflect that the first NRW Physics move is no longer only source- and mapping-backed, but also partially committed in canonical applicability:
curricula/DE/Gymnasium/provenance/nrw-physics-onboarding.md
curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/README.md

Interpretation:

this is the first learner-visible NRW Physics step that persists beyond the source lane and mapping fixture into the canonical applicability surface
the NRW Physics lane still remains a reviewed partial-bridge pilot rather than a broad P5 cutover lane, so its APV-202 debt is retained intentionally and documented instead of being treated as unresolved drift
the next clean move is now either one further NRW corridor that can justify another committed applicability widening, or the first Baden-Wuerttemberg upper-secondary Physics source lane

2026-04-11: NRW Physics matter-structure follow-on replaces the broad Standardmodell bridge with a narrow canonical atom

What changed:

the canonical Physics landscape now contains a new narrow Q4 atom:
b3f3f4f7-b5cc-40e1-b57a-3d93649baa61 Elementare Bestandteile der Materie mit Strukturmodellen ordnen
the new atom sits under the existing parent cluster:
7add799b-2d76-58db-81e5-d54393718f50 Elementarteilchen und Standardmodell
its provenance is repository-backed in:
curricula/DE/Gymnasium/provenance/canonical-goal-provenance-registry.json
the NRW mapping lane now retargets the imported LK matter child e59d5e73-3e45-49b4-825c-11fc5a41310d away from the broader Standardmodell cluster and onto that new narrow atom:
curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/nrw_physics_upper_secondary_to_canonical_physics.json
after applicability persistence, both the new atom and its parent cluster now carry DE-NW in the canonical Physics file
the accepted-warning registry now records the one new NRW-specific APV-202 on the narrow atom:
docs/qa-ci/applicability-accepted-warnings.json

Validation used:

cd app && APPLICABILITY_APPLY_SCOPE=7f6fc60c-9fcc-4cc2-b07e-f897a1d0338a npm run apply:applicability
cd app && npm run validate:view-filters --silent | rg '\[7f6fc60c-9fcc-4cc2-b07e-f897a1d0338a\]|error\(s\)|warning\(s\)|accepted warning\(s\)'
python3 scripts/render_canonical_physics_bundesland_status.py

Interpretation:

this is cleaner than the earlier broad cluster bridge because the new canonical atom matches the NRW wording directly without dragging in the stronger interactions/research scope of the full Standardmodell package
the parent cluster can now become DE-NW-visible through normal child-union instead of through a direct broad bridge or a retained override
the NRW Physics lane still stays in reviewed partial-bridge territory on this slice, but the matter branch is now narrower and more stable than before

2026-04-11: NRW Physics exact-resolves the mixed GK E/B-field clause through two narrow canonical Q1 atoms

What changed:

the imported NRW GK field clause 70de8e83-2dad-476b-b16a-9a8ab347f13b is no longer treated as one mapped atomic residue:
in the NRW source snapshot it is now a cluster with two new children
the shared NRW Physics source membership and closure registries now reflect 29 source goals instead of 27
the canonical Physics landscape now contains two new narrow Q1 atoms:
741774ef-15fc-4bcf-a370-e2c5cf4257d0 Geladene Teilchen in homogenen elektrischen Feldern untersuchen
9854589c-5feb-4942-b90f-311ddf36eb78 Geladene Teilchen in homogenen magnetischen Feldern untersuchen
both new canonical atoms are repository-backed in:
curricula/DE/Gymnasium/provenance/canonical-goal-provenance-registry.json
the NRW mapping lane now replaces the earlier broad parent-level partial on canonical Q1 Elektrisches und magnetisches Feld with two narrow exact bridges:
cfcada5e-df7c-4803-894d-bd5784a38850 -> 741774ef-15fc-4bcf-a370-e2c5cf4257d0
d6a20f83-15f7-4305-8844-b6ca0883cfcc -> 9854589c-5feb-4942-b90f-311ddf36eb78
the repository-backed NRW Physics mapping fixture therefore now carries 20 entries instead of 19
after applicability persistence, the new atoms and their reviewed Q1 parent path now carry DE-NW:
Bewegung geladener Teilchen im elektrischen Feld
Mikroskopische und makroskopische Wirkung magnetischer Felder
Magnetisches Feld
Q1 Elektrisches und magnetisches Feld

cd backend && ./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
python3 scripts/render_canonical_physics_bundesland_status.py

Interpretation:

this is cleaner than the earlier parent-level partial on Q1 Elektrisches und magnetisches Feld, because the imported NRW wording is now resolved at the same granularity at which the shared Q1 field surface actually branches
unlike the earlier matter follow-on, this step does not add new accepted-warning debt, because both NRW child bridges now land on matching narrow canonical atoms as exact
the mixed NRW parent Klassische Wellen und Teilchen in Feldern still stays intentionally unmapped as a parent package; only its reviewed electric and wave subcorridors now carry committed NRW applicability

2026-04-11: NRW Physics exact-resolves the GK Quantenobjekte children through two narrow canonical Q4 atoms

What changed:

the canonical Physics landscape now contains two new narrow Q4 entry atoms under Quantenobjekte:
a359c859-eee0-40ef-a9d1-88db2e6c55b2 Photonen und Elektronen als Quantenobjekte beschreiben
defe44d2-c3d3-456b-a786-fad2cef13fe8 Die Bedeutung von Modellen an Photon und Elektron reflektieren
both new atoms are provenance-backed in:
curricula/DE/Gymnasium/provenance/canonical-goal-provenance-registry.json
the NRW mapping lane now retargets the two imported GK child atoms away from the broad Q3 Welle-Teilchen-Dualismus cluster and onto those new narrow Q4 atoms as exact:
cc33e6c0-4f16-401d-ac77-4ce89025609f -> a359c859-eee0-40ef-a9d1-88db2e6c55b2
9d6c16e1-30ad-4f1b-a7cb-348b1a2f7591 -> defe44d2-c3d3-456b-a786-fad2cef13fe8
the NRW GK parent Qualifikationsphase GK: Quantenobjekte still keeps its reviewed partial bridge onto the canonical Q3 surface Welle-Teilchen-Dualismus
after applicability persistence, the two new atoms and the shared canonical Q4 cluster Quantenobjekte now all carry DE-NW

cd backend && ./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
python3 scripts/render_canonical_physics_bundesland_status.py

Interpretation:

this is cleaner than a direct broad bridge onto canonical Quantenobjekte, because the two NRW GK child wordings are now resolved as exact entry atoms instead of being forced onto the deeper Q4 package as one unspecific cluster claim
unlike the radiation and matter follow-ons, this step does not create new accepted-warning debt; the new NRW widening is exact and the shared Q4 Quantenobjekte cluster follows through child-union
all currently reviewed NRW Physics mapping targets now carry committed DE-NW applicability, so the next clean move is no longer another repair on the same reviewed target set but either a genuinely new NRW source corridor or the next Bundesland lane

2026-04-11: Baden-Wuerttemberg upper-secondary Physics opens the first reviewed field corridor

What changed:

the official Baden-Wuerttemberg Gymnasium Physics PDF is now archived locally at:
curricula/DE/Gymnasium/input/BW/BP2016BW_ALLG_GYM_PH.pdf
the first BW upper-secondary Physics source snapshot now exists at:
curricula/DE/Gymnasium/input/BW/upper-secondary/source-json/DE_BAW_S_GYM_2_PHYSIK.de.json.snapshot
the new source lane is now active in the shared DE-level provenance registries:
curricula/DE/Gymnasium/provenance/source-landscape-registry.json
curricula/DE/Gymnasium/provenance/source-goal-membership-registry.json
curricula/DE/Gymnasium/provenance/source-goal-closure-registry.json
the repository-backed BW upper-secondary Physics mapping lane now exists at:
curricula/DE/Gymnasium/mapping/DE-BW/upper-secondary/bw_physics_upper_secondary_to_canonical_physics.json
the first reviewed BW field corridor carries 7 mappings:
BW source root -> canonical Physics root (partial)
shared orientation anchor -> shared canonical motivation anchor (exact)
Basisfach Elektromagnetische Felder parent -> shared canonical Q1 field surface (partial)
Basisfach child Elektrische und magnetische Felder im Basisfach beschreiben -> shared canonical Q1 field surface (partial)
Leistungsfach Elektromagnetische Felder parent -> shared canonical Q1 field surface (partial)
Leistungsfach child Elektrisches Feld im Leistungsfach untersuchen -> canonical Elektrisches Feld cluster (partial)
Leistungsfach child Magnetisches Feld im Leistungsfach untersuchen -> canonical Magnetisches Feld cluster (partial)
the BW onboarding note, mapping-lane README, M2 shortlist, rollout tracker, and rendered quick view now reflect that Baden-Wuerttemberg is a real fourth active Physics state on the canonical path:

the rendered Physics Bundeslaender quick view now shows 4/4 tracked states with active snapshots and first reviewed corridors

Interpretation:

Baden-Wuerttemberg is no longer only a reserved or source-only Physics lane; it now has the first real reviewed upper-secondary corridor on the shared canonical field surface
this move deliberately stops before Elektrodynamik, Schwingungen, Wellen, any BW-specific Physics composition views, or a new BW applicability persistence pass from this lane
the next clean BW Physics move is therefore an adjacent follow-on on Elektrodynamik, Schwingungen, or Wellen, not a broader state-specific tree or applicability sweep

2026-04-11: Baden-Wuerttemberg upper-secondary Physics adds the first LF electrodynamics follow-on and a small committed applicability cut

What changed:

the BW upper-secondary Physics source snapshot now widens the first reviewed corridor with one adjacent Leistungsfach Elektrodynamik cluster plus three new atomic children:
Bewegungsinduktion und Ladungstrennung
Induktionsgesetz und Lenz'sche Regel
Selbstinduktion und Induktivitaet
the repository-backed BW upper-secondary mapping lane now carries 10 reviewed mappings:
the previous 7 field-corridor mappings remain in place
three new exact bridges now connect the BW LF electrodynamics atoms onto the shared canonical induction surface
the BW provenance-backed source registries now include the widened snapshot closure:
curricula/DE/Gymnasium/provenance/source-goal-membership-registry.json
curricula/DE/Gymnasium/provenance/source-goal-closure-registry.json
the canonical Physics file now persists the resulting small DE-BW applicability cut across the field/induction closure:
curricula/DE/Gymnasium/canonical/DE_DEU_S_GYM_CANONICAL_PHYSIK.de.json
the BW onboarding note, mapping-lane README, rollout tracker, shortlist, and rendered quick view now reflect the widened corridor plus the scoped applicability persistence:

the rendered Physics Bundeslaender quick view now keeps Baden-Wuerttemberg at P4, but shows Applicability yes, Mappings 10, and a state projection with 18 visible goals and 0 warnings on the committed BW field/induction slice

Interpretation:

this is still a narrow reviewed BW lane, not a broad P5 state coverage claim; the committed applicability cut is intentionally scoped to the already reviewed field/induction closure
the clean gain over the prior BW step is that the electrodynamics follow-on now lands on exact shared canonical induction atoms, so the first BW committed applicability persistence does not introduce new accepted-warning debt
the next clean BW Physics move remains the still-missing Basisfach Elektrodynamik residue or the adjacent Schwingungen / Wellen surfaces, not BW-specific composition views or a broader applicability sweep

2026-04-11: Baden-Wuerttemberg upper-secondary Physics adds the Basisfach electrodynamics induction strip

What changed:

the BW upper-secondary Physics source snapshot now widens the imported Basisfach side with one adjacent Basisfach: Elektrodynamik cluster plus three retained atomic children:
Bewegungsinduktion und Ladungstrennung im Basisfach
Induktionsgesetz und Lenz'sche Regel im Basisfach
Selbstinduktion und Induktivitaet im Basisfach
the repository-backed BW upper-secondary mapping lane now carries 14 reviewed mappings:
the earlier 10 reviewed mappings remain in place
the new Basisfach electrodynamics parent now bridges conservatively onto the canonical induction cluster (partial)
the new Basisfach induction leaves now bridge onto the shared canonical induction atoms with one exact alignment on Bewegungsinduktion and two conservative partial alignments on Induktionsgesetz and Selbstinduktion
the BW provenance-backed source registries now include the widened snapshot membership and closure for 15 source goals and 10 atomic descendants under the active root:
curricula/DE/Gymnasium/provenance/source-goal-membership-registry.json
curricula/DE/Gymnasium/provenance/source-goal-closure-registry.json

the rendered Physics Bundeslaender quick view now keeps Baden-Wuerttemberg at P4, still with Applicability yes, but updates the BW lane to Mappings 14

Interpretation:

this keeps the BW lane narrow and source-led: the imported Basisfach Elektrodynamik row is only widened on the induction strip, while the remaining source residue on technical applications and Maxwell overview is still intentionally deferred
the two new Basisfach partial atom bridges do not create new accepted-warning debt, because the corresponding canonical induction targets already carry committed DE-BW applicability from the earlier LF follow-on
the next clean BW Physics move is now either the still-unmapped BF technische Anwendungen / Maxwell-Ueberblick residue of 3.4.2.2 Elektrodynamik or the adjacent Schwingungen / Wellen surfaces

2026-04-11: Baden-Wuerttemberg upper-secondary Physics anchors the BF induction-applications residue on one new canonical atom

What changed:

the BW upper-secondary Physics source snapshot now retain-splits the remaining Basisfach 3.4.2.2 Elektrodynamik residue into two explicit children:
Technische Anwendungen des Induktionsgesetzes im Basisfach beschreiben
Elektromagnetische Felder im Maxwell-Ueberblick beschreiben
the repository-backed BW upper-secondary mapping lane now carries 15 reviewed mappings:
the new Basisfach applications child now exact-anchors onto one new narrow canonical atom Technische Anwendungen des Induktionsgesetzes qualitativ beschreiben
the new Maxwell-overview child remains intentionally ungemappt
the canonical Physics file now contains that new narrow induction-applications atom under the shared Q2 induction cluster:
curricula/DE/Gymnasium/canonical/DE_DEU_S_GYM_CANONICAL_PHYSIK.de.json
the canonical-goal provenance registry now records the new canonical atom as source-led from the BW Basisfach applications child:

Interpretation:

this is cleaner than forcing the BW Basisfach applications wording onto the narrower existing Wirbelströme und Waltenhofen-Pendel context leaf; the new canonical applications atom is broad enough for generator/transformator/induction-device examples without dragging the Maxwell clause into the same bridge
the new BW widening stays debt-neutral: the new BW applications bridge is exact, and the already committed BW field/induction closure required no further applicability file changes
the next clean BW Physics move is now either the still-unmapped BF Maxwell-Ueberblick residue of 3.4.2.2 Elektrodynamik or the adjacent Schwingungen / Wellen surfaces

2026-04-11: Baden-Wuerttemberg upper-secondary Physics closes the BF Maxwell-overview residue on one new canonical atom

this is cleaner than trying to force the BW Maxwell clause into the canonical Elektromagnetische Wellen package; the new narrow atom states exactly the overview claim the source wording makes, without overclaiming the later Q3 wave surface
the new BW widening also stays debt-neutral: the new Maxwell-overview bridge is exact, and the already committed BW field/induction closure again required no further applicability file changes
the next clean BW Physics move now shifts fully onto the adjacent Schwingungen / Wellen surfaces

2026-04-11: Baden-Wuerttemberg upper-secondary Physics adds the first BF Schwingungen follow-on

What changed:

the BW upper-secondary Physics source snapshot now widens the imported Basisfach side with one adjacent Basisfach: Schwingungen cluster plus six retained atomic children:
Schwingungen experimentell aufzeichnen und als periodische Bewegungen beschreiben
Ungedaempfte harmonische Schwingungen mathematisch beschreiben
Lineare Rueckstellkraft bei harmonischen mechanischen Schwingungen beschreiben
Schwingung eines Federpendels und Energieumwandlungen beschreiben
Schwingung in einem elektromagnetischen Schwingkreis und Energieumwandlungen beschreiben
Mechanische und elektromagnetische Schwingungen vergleichen
the repository-backed BW upper-secondary mapping lane now carries 21 reviewed mappings:
the earlier 16 reviewed mappings remain in place
the new Basisfach Schwingungen parent now bridges conservatively onto the shared canonical Q2 surface Schwingungen, Induktion und mechanische Wellen
four new conservative partial bridges now connect the imported Basisfach Schwingungen children onto the existing canonical Q2 atoms Harmonische Schwingung verstehen, Charakteristische Schwingungsgroessen, Energie und Energieerhaltung in Schwingungen, and Elektromagnetischen Schwingkreis analysieren
the retained source children on lineare Rueckstellkraft and on the explicit comparison of mechanischen versus elektromagnetischen Schwingungen stay intentionally source-led
the scoped canonical Physics applicability persistence now widens the earlier BW field/induction cut onto the shared Q2 oscillation strip, and the four resulting BW-only APV-202 findings are now explicitly accepted:

this is cleaner than inventing new canonical oscillation atoms for BW immediately; the imported Basisfach Schwingungen wording is now narrowed to a reviewed source split first, and only the four cleanest alignments land conservatively on existing shared Q2 targets
the widening now also commits the resulting BW visibility on the shared Q2 oscillation strip instead of leaving APV-203 drift in the canonical Physics file; the remaining four BW-only APV-202 findings are intentionally accepted because the bridges stay conservative partial
the next clean BW Physics move is now either the adjacent Wellen surface or the still-unopened Leistungsfach Schwingungen strip, not BW-specific composition views or a broader applicability sweep

2026-04-11: BW upper-secondary Physics opens the adjacent Basisfach `Wellen` corridor

Observed repo state:

the Bavaria Chinese pilot now adds 35 reviewed mappings into the canonical DE Chinese layer, yielding 33 committed DE-BY applicability nodes plus a direct Bavaria Chinesisch cutover path into Gymnasium (DE)
the Hessen Sek-I mathematics landscape now carries 33 explicit mappings and reaches reviewed row coverage beyond the old function/quadratic slice: J5 number basics, linear equations/inequalities, quadratic binomial-form routes, roots, similarity/Strahlensatz, Pythagoras, circle/cylinder, and integer-exponent rules
the reviewed Hessen Sek-I mathematics landscape no longer carries any APV-202 findings; remaining reviewed math debt is now limited to the two Bayern override-backed APV-201 cases
the Hessen Sek-I physics mechanics bridge now closes the old 7.4 Mechanik row at exact reviewed coverage: a dedicated canonical density/mass/volume atom plus exact row- and subrow-mappings now cover the full Hessen mechanics anchor, while Kräfteigenschaften nutzen and 10.1 Arbeit und Energie already bind to their own reviewed canonical targets
the Hessen Sek-I physics heat bridge now closes the foundational 7.2 Wärmelehre row at exact reviewed coverage: temperature/heat, temperature measurement and expansion, particle model, and heat transfer all map exactly into a dedicated canonical Sek-I heat cluster that also backs the later J10 heat-energy route
the Hessen Sek-I physics optics bridge now spans both reviewed source rows 7.1 Optik 1 and 8.1 Optik 2: light propagation, ray model, reflection, lens imaging, vision, and simple optical instruments all map exactly into dedicated canonical Sek-I optics anchors
the Hessen Sek-I physics electricity bridge now spans both reviewed source rows 7.3 Magnetismus und Elektrizität 1 and 8.2 Elektrizität 2: magnets, simple circuits, current effects, current measurement, static electricity/voltage, current-voltage relation, resistor circuits, and electrical safety all map exactly into dedicated canonical Sek-I electricity anchors
the Hessen Sek-I physics pressure/buoyancy bridge now closes the fakultative 8.3 Druck und Auftrieb row at exact reviewed coverage: pressure in liquids and gases, qualitative pressure-temperature relations, Archimedes' principle, and first flight/air-resistance interpretations all map exactly into a dedicated canonical Sek-I pressure-and-buoyancy cluster that depends on the reviewed mechanics base and reuses the reviewed heat bridge for the gas-pressure branch
the Hessen Sek-I physics acoustics bridge now closes the fakultative 8.3b Akustik row at exact reviewed coverage: sound sources, sound propagation, pitch/loudness, hearing/noise, and music-related sound phenomena all map exactly into a dedicated canonical Sek-I acoustics cluster that reuses the reviewed particle-model anchor and now also feeds the upper-secondary Q2 wave entry point
the Hessen Sek-I physics colors bridge now closes the fakultative 8.3c Farben row at exact reviewed coverage: color origin/decomposition, additive and subtractive color mixing, simple color perception, and technical color applications all map exactly into a dedicated canonical Sek-I colors cluster that reuses the reviewed light-propagation anchor and now also feeds the upper-secondary Q3 electromagnetic-spectrum entry point
the Hessen Sek-I physics radioactivity bridge now closes the non-fakultative 10.2 Radioaktivität row at exact reviewed coverage: atomic structure, radiation detection/effects, and applications/risks all map exactly into a dedicated canonical Sek-I radioactivity cluster that now also feeds the upper-secondary nuclear-physics entry point
the Hessen Sek-I physics work/energy bridge now reaches into the J10 continuation of 10.1 Arbeit und Energie: Wärme als Energieform and Elektrische Energie nutzen both map exactly into dedicated canonical energy atoms, with the heat-energy route depending explicitly on the reviewed Sek-I heat bridge and the electrical-energy route on the reviewed voltage bridge
the Hessen Sek-I chemistry foundations bridge now closes the full reviewed 8.1 Stoffe – Strukturen – Eigenschaften row at exact coverage: hazard symbols/safety rules and separation methods now join the already adopted working-methods, substance, state, solution, and first acid-base anchors, so the old 8.1 cluster itself now maps exactly into the canonical Sek-I chemistry foundations cluster
the Hessen Sek-I chemistry reactions bridge now extends the reviewed adoption into 8.2 Chemische Reaktion – Stoff- und Energieumsatz: reaction characteristics, simple oxidation/reduction, combustion, reaction energy, and conservation of mass all map exactly into a dedicated canonical Sek-I reactions cluster, and the upper-secondary Einfache Redoxreihen aufstellen route now depends explicitly on the projected Sek-I redox anchor
the Hessen Sek-I chemistry symbol-language bridge now closes the reviewed 9.1 Chemische Symbolsprache und Anwendung row at exact coverage: constant proportions, Dalton model, chemical symbols/formulas, simple reaction equations, and first redox schemes all map exactly into a dedicated canonical Sek-I symbol-language cluster that reuses the reviewed 8.2 reactions bridge
the Hessen Sek-I chemistry ions/electrolysis bridge now closes the reviewed 9.3 Elektrolyse und Ionenbegriff row at exact coverage: conductivity, ions as charge carriers, and electrolysis of aqueous salt solutions all map exactly into a dedicated canonical Sek-I ions/electrolysis cluster that reuses the reviewed 9.1 symbol-language bridge and now also backs the upper-secondary Elektrolyse beschreiben route
the Hessen Sek-I chemistry atomic-structure bridge now closes the reviewed 10.1 Atombau, Periodensystem und Ionenbindung row at exact coverage: core-shell model, Bohr energy levels, periodic-table orientation, ion formation via noble-gas rule, and ionic bonding all map exactly into a dedicated canonical Sek-I atomic-structure-and-bonding cluster that reuses the reviewed 9.1 symbol-language bridge and now also backs the upper-secondary Bindungsmodelle sicher nutzen route
Explicit learner cutover path to Gymnasium (DE) exists in backend and UI
Bulk cutover path for operators exists
the Hessen Sek-I learner cutover path now also covers the frozen mixed overview root across the currently supported Mathematik/Physik/Chemie/Biologie/Französisch surface; lower-secondary physics still auto-selects canonical mathematics for the existing bridge prerequisites, and lower-secondary French now cuts over onto the shared canonical French landscape instead of blocking mixed-overview retirement
the first Bavaria learner cutover path is now operational for direct legacy Mathematik learners: Bavaria Mathematik can migrate into Gymnasium (DE) with the root filter DE-BY, canonical Mathematics selected, and normalized planned-scope continuation on the shared canonical Math spine
ordinary learner entry now also prefers the canonical DE path over the Bavaria legacy root: Gymnasium (Bayern) is hidden by default from general overview/bootstrap surfaces and only retained when it is already the active learner selection
the active Bavaria Math/Physics/Chemistry/Biology/Informatik/Geschichte/Deutsch/Englisch/Französisch/Spanisch/Italienisch/Russisch/Polnisch/Tschechisch/Griechisch/Wirtschaft_und_Recht/Politik_und_Gesellschaft/Latein/Musik/Chinesisch adopted corridor no longer hangs off the retired curricula/DE/BY/Gymnasium path: the adopted Bavaria mappings now live under curricula/DE/Gymnasium/mapping/DE-BY/gymnasium/, the shared source-landscape registry now exposes archiveSourcePath for the current adopted Bavaria source landscapes, and scripts/validate_bavaria_gymnasium_archive_paths.py plus scripts/validate_bavaria_gymnasium_legacy_refs.py now fence the DE-level retained-source lane and repo-level operational references
the currently supported Bavaria legacy mathematics learner path is now detached as an active runtime path: direct Mathematik sessions are frontend- and backend-read-only retirement views, UI/AI write endpoints reject mutations, and the canonical Gymnasium (DE) + DE-BY cutover remains the supported continuation
the current Bavaria Physics pilot surface now has the same direct learner-cutover and retirement handling: direct legacy Physik learners migrate into Gymnasium (DE) with DE-BY, canonical Physics selected plus the required Math bridge, and active legacy Physics sessions are frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria Chemistry and Biology pilot surfaces now also have direct learner-cutover and retirement handling: direct legacy Chemie and Biologie learners migrate into Gymnasium (DE) with DE-BY, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria Informatics pilot surface now also has direct learner-cutover and retirement handling: direct legacy Informatik learners migrate into Gymnasium (DE) with DE-BY, canonical Informatics selected, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria German pilot surface now also has direct learner-cutover and retirement handling: direct legacy Deutsch learners migrate into Gymnasium (DE) with DE-BY, canonical German selected with the default GK filter, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria English pilot surface now also has direct learner-cutover and retirement handling: direct legacy Englisch learners migrate into Gymnasium (DE) with DE-BY, canonical English selected with the default GK filter, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria French pilot surface now also has direct learner-cutover and retirement handling: direct legacy Französisch learners migrate into Gymnasium (DE) with DE-BY, canonical French selected with the default GK filter, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria Spanish pilot surface now also has direct learner-cutover and retirement handling: direct legacy Spanisch learners migrate into Gymnasium (DE) with DE-BY, canonical Spanish selected with the default GK filter, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria Italian pilot surface now also has direct learner-cutover and retirement handling: direct legacy Italienisch learners migrate into Gymnasium (DE) with DE-BY, canonical Italian selected with the default GK filter, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria Russian pilot surface now also has direct learner-cutover and retirement handling: direct legacy Russisch learners migrate into Gymnasium (DE) with DE-BY, canonical Russian selected with the default GK filter, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria Polish pilot surface now also has direct learner-cutover and retirement handling: direct legacy Polnisch learners migrate into Gymnasium (DE) with DE-BY, canonical Polish selected with the default GK filter, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria Czech pilot surface now also has direct learner-cutover and retirement handling: direct legacy Tschechisch learners migrate into Gymnasium (DE) with DE-BY, canonical Czech selected with the default GK filter, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria History pilot surface now also has direct learner-cutover and retirement handling: direct legacy Geschichte learners migrate into Gymnasium (DE) with DE-BY, canonical History selected with the default GK filter, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria Greek pilot surface now also has direct learner-cutover and retirement handling: direct legacy Griechisch learners migrate into Gymnasium (DE) with DE-BY, canonical Greek selected with the default GK filter, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria Wirtschaft-und-Recht pilot surface now also has direct learner-cutover and retirement handling: direct legacy Wirtschaft und Recht learners migrate into Gymnasium (DE) with DE-BY, canonical Wirtschaftswissenschaften selected, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria Politik-und-Gesellschaft pilot surface now also has direct learner-cutover and retirement handling: direct legacy Politik und Gesellschaft learners migrate into Gymnasium (DE) with DE-BY, canonical Politik und Wirtschaft selected with the default GK filter, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria Latin pilot surface now also has direct learner-cutover and retirement handling: direct legacy Latein learners migrate into Gymnasium (DE) with DE-BY, canonical Latin selected with the default GK filter, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria Music pilot surface now also has direct learner-cutover and retirement handling: direct legacy Musik learners migrate into Gymnasium (DE) with DE-BY, canonical Music selected with the default GK filter, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
the current Bavaria Chinese pilot surface now also has direct learner-cutover and retirement handling: direct legacy Chinesisch learners migrate into Gymnasium (DE) with DE-BY, canonical Chinese selected with the default GK filter, and active legacy sessions now run as frontend- and backend-read-only retirement views instead of ordinary writable learner paths
Bavaria Math/Physics/Chemistry/Biology source-goal closures and goal memberships now also live in the shared DE-level provenance registries curricula/DE/Gymnasium/provenance/source-goal-closure-registry.json and curricula/DE/Gymnasium/provenance/source-goal-membership-registry.json, so the current adopted Bavaria corridor no longer depends on the live legacy tree for archived closure or membership lookups
the full live Bavaria Gymnasium legacy tree now classifies as compatibility-only on the active runtime path: explicit UI/AI curriculum selection no longer routes fresh learners back into Bavaria legacy root or subject views, while general learner entry continues to prefer Gymnasium (DE) and existing retired sessions remain archive/cutover-only
ordinary learner entry now also prefers the canonical DE path over Hessen Sek-I legacy roots: lower-secondary Hessen landscapes are hidden by default from the general overview/bootstrap surface and only reappear when they are already the active selection
the frozen Hessen Sek-I source-JSON lane is now mirrored under curricula/DE/Gymnasium/input/HE/lower-secondary/source-json/ (6 files), and the shared source-landscape registry now also offers archiveSourcePath for those lower-secondary landscapes so provenance survives outside the live legacy tree
Hessen Sek-I source-goal atomic closures and goal memberships now also live in the shared DE-level provenance registries curricula/DE/Gymnasium/provenance/source-goal-closure-registry.json and curricula/DE/Gymnasium/provenance/source-goal-membership-registry.json, so lower overview/root survival no longer depends on expanding the live legacy tree for archived closure or membership lookups
Hessen Sek-I legacy learner sessions are now detached as active runtime paths across the currently supported lower-secondary bundle: Mathematik/Physik/Chemie/Biologie/Französisch sessions, including mixed overview sessions that resolve into that bundle, are frontend- and backend-read-only once the canonical cutover surface is available
Hessen Sek-I legacy-to-canonical mapping fixtures now also live in the DE-level archive lane curricula/DE/Gymnasium/mapping/DE-HE/lower-secondary/
frozen Hessen Sek-I compatibility summaries and topic lists now also resolve from the DE-level archive registries curricula/DE/Gymnasium/archive/compatibility-landscape-registry.json and curricula/DE/Gymnasium/archive/compatibility-topic-summary-registry.json
scripts/validate_hessen_lower_secondary_archive_paths.py and scripts/validate_hessen_lower_secondary_legacy_refs.py now fence retained-asset and repo-level references for Hessen Sek-I, and both checks are wired into .github/workflows/ci.yml plus local run_ci.sh
the Hessen lower-secondary delete handoff has now been executed: the original tree is gone from the active repo path, and bash scripts/run_hessen_lower_secondary_delete_handoff_dry_run.sh now serves as the post-retirement verification command against the surviving archive/provenance/mapping lanes
Hessen upper-secondary legacy-to-canonical mapping fixtures now live in the DE-level archive curricula/DE/Gymnasium/mapping/DE-HE/upper-secondary/
Hessen upper-secondary source-landscape jurisdiction metadata now lives in the DE-level provenance registry curricula/DE/Gymnasium/provenance/source-landscape-registry.json, and both backend state filtering and the applicability compiler read from that stable path
Hessen upper-secondary source-goal atomic closures now live in the DE-level provenance registry curricula/DE/Gymnasium/provenance/source-goal-closure-registry.json, and canonical champion/topic metrics can read that frozen closure instead of expanding the live legacy tree
Hessen upper-secondary source-goal memberships now also live in the DE-level provenance registry curricula/DE/Gymnasium/provenance/source-goal-membership-registry.json, and Hessen cutover can infer subject membership for stored legacy planned/active goal IDs without loading the live legacy source tree
learner-facing curriculum selection now exposes frozen Hessen upper-secondary roots and subjects as explicit compatibility views instead of mixing them into the ordinary recommended selection flow
ordinary session-start and championship-registration pickers now hide compatibility views by default and only retain them when they are already the active selection
backend bootstrap for new learners now also delivers recommended curricula without compatibility views by default, and /api/ui/landscapes supports an explicit includeCompatibility switch instead of forcing the frontend to guess
the learner cockpit setup now also demotes Hessen compatibility subjects into an explicitly revealable secondary section, and canonical Gymnasium (DE) setups prune stale Hessen compatibility entries from persisted personal curriculum configs
when a learner is still inside a Hessen compatibility session, the cockpit setup dialog now runs in retirement-only mode instead of acting as a normal curriculum editor; migration/audit remain available there, but regular curriculum reconfiguration is no longer part of that path
the learner cockpit now also treats open Hessen compatibility sessions as read-only/audit-only for planning, active-goal selection, and SRS drilling; the legacy session remains visible, but no longer behaves like a normal active learning path
UI and AI write endpoints now also reject compatibility-session writes server-side for curriculum mutation, planning, active-goal changes, mastery, and client-state updates, so the retained Hessen route is backend-read-only as well as frontend-read-only
UI and AI learner-state routes no longer serve retained Hessen compatibility sessions at all as live state views; instead, the UI exposes a dedicated compatibility-archive export that snapshots the retired Hessen state for audit/recovery
the compatibility-archive export now resolves retired Hessen curriculum summaries from the frozen DE-level archive registry curricula/DE/Gymnasium/archive/compatibility-landscape-registry.json and serializes raw persisted learner state, so archive generation no longer depends on projecting a live legacy landscape graph
/api/ui/landscapes?includeCompatibility=true now also resolves Hessen compatibility summaries from the frozen DE-level archive registry curricula/DE/Gymnasium/archive/compatibility-landscape-registry.json, so compatibility overview/listing metadata no longer depends on loaded Hessen upper-secondary landscape files
/api/ui/curricula/{curriculumId}/topics now also resolves Hessen compatibility topic lists from the frozen DE-level archive registry curricula/DE/Gymnasium/archive/compatibility-topic-summary-registry.json, and direct Hessen compatibility /api/ui/landscapes/{id} plus /closure routes are retired
the Abi26 Hessen mathematics bootstrap now provisions learners onto canonical Gymnasium (DE) with the DE-HE root filter plus canonical mathematics GK/LK scope, instead of selecting the retired Hessen mathematics curriculum directly
new UI and AI curriculum-selection writes now also reject retired Hessen compatibility IDs even when a caller already knows them, so compatibility routes are no longer re-openable as fresh learner selections
Hessen upper-secondary exam/deploy/adoption helper tooling now resolves retained abi/ defaults plus archived mapping defaults from the DE-level lanes curricula/DE/Gymnasium/input/DE-HE/ and curricula/DE/Gymnasium/mapping/DE-HE/upper-secondary/ via a shared retained-asset registry, while legacy subject-landscape lookup is centralized through the DE-level provenance source registry instead of per-script hardcoded legacy paths
DE-level Hessen abi/ operational metadata now follows the same handoff: task_bank.json stores sourceLandscapeId plus curricula/DE/Gymnasium/provenance/source-landscape-registry.json instead of embedding legacy landscape file paths, and blueprint/source-catalog/release-bundle source references now point only at retained DE-level curricula/DE/Gymnasium/input/DE-HE/... assets
repo-authored Hessen abi/ markdown (exam-pipeline.md, physics authoring/QS docs, LEIFI README) is now aligned to the same DE-level archive/provenance lane; remaining legacy path strings inside HE/abi/ are confined to imported/raw archival texts such as source-extracted markdown and official text excerpts
that remaining raw-provenance boundary is now machine-checked by scripts/validate_hessen_upper_secondary_archive_paths.py, with the explicit allowlist stored in curricula/DE/Gymnasium/input/HE/retained-asset-registry.json
the Hessen upper-secondary archive-boundary validator is now wired into both .github/workflows/ci.yml (graph-validation) and local run_ci.sh, so regressions on retained-vs-raw archive path usage fail the standard QA path instead of relying on ad-hoc manual checks
the remaining repo-level references to curricula/DE/HE/Kultusministerium/Gymnasiale_Oberstufe are now also narrowed to an explicit handoff allowlist in curricula/DE/Gymnasium/provenance/hessen-upper-secondary-retirement-registry.json; active operational surfaces are machine-checked by scripts/validate_hessen_upper_secondary_legacy_refs.py, and the old root helper scripts no longer carry hardcoded Hessen legacy defaults
backend/src is now free of explicit Hessen upper-secondary tree references; the remaining allowlisted repo-level references are reduced to 7 explicit handoff files: provenance/input descriptors plus the validator/dry-run scripts that police that boundary
the frozen Hessen upper-secondary source-JSON lane is now mirrored under curricula/DE/Gymnasium/input/HE/upper-secondary/source-json/ (39 files), and the shared source-landscape registry now offers archiveSourcePath so tooling can read those snapshots without depending on the live legacy tree
backend landscape loading now also falls back to those archived Hessen upper-secondary source snapshots, so retired curriculum IDs remain resolvable for release metadata, frontier invariants, and explicit retirement/conflict handling even after the old tree is gone
the Hessen upper-secondary delete handoff has now actually been executed: curricula/DE/HE/Kultusministerium/Gymnasiale_Oberstufe is gone from the active repo path, and bash scripts/run_hessen_upper_secondary_delete_handoff_dry_run.sh now serves as the post-retirement verification command over the surviving DE-level archive/provenance lanes
scripts/validate_hessen_upper_secondary_legacy_refs.py now enforces not only the allowlisted textual reference boundary, but also that the retired Hessen upper-secondary tree stays absent from the active repo
Reviewed canonical landscapes now carry committed node-level applicability; the currently enforced CI set now covers the full committed DE Gymnasium canonical set: Mathematik, Physik, Chemie, Biologie, Informatik, Deutsch, Englisch, Französisch, Griechisch, Chinesisch, Geschichte, Politik und Wirtschaft, Musik, Latein, Spanisch, Italienisch, Russisch, Polnisch, Tschechisch, Wirtschaft, Overview
validate:view-filters is now clean on active reviewed findings for that scope: 0 errors, 0 active warnings, 139 accepted warnings recorded in docs/qa-ci/applicability-accepted-warnings.json
curricula/DE/HE/Kultusministerium/Gymnasiale_Oberstufe has now crossed from legacy_view_retained to legacy_deleted at tree level: only the DE-level input/provenance lanes survive as operational artifacts
curricula/DE/HE/Kultusministerium/Gymnasiale_Oberstufe is the first tracked legacy source tree that has actually been deleted from the active repo
the migration has therefore entered the explicit close-out phase: the remaining work is now dominated by optional scope extension questions, not legacy tree retirement

Input transfer lane

Deleting old legacy source trees requires more than canonical JSON plus mappings.

We also need a migration lane for the legacy source inputs, especially:

input/ source material used to derive goals
abi/ state-specific exam and release material
any still-needed references that are currently only reachable through legacy paths

Rule:

canonical DE landscapes stay shared and non-state-specific
transferred source inputs must stay explicitly state-scoped
the same state-scoped rule applies to retained non-canonical materials beyond pure input/, with curricula/DE/Gymnasium/input/HE/abi as the clearest current example

Recommended target structure:

curricula/DE/Gymnasium/input/
  DE-HE/
    upper-secondary/
    lower-secondary/
    abi/
  DE-BY/
    gymnasium/
    abi/

Practical meaning:

the canonical graph lives once under curricula/DE/Gymnasium/canonical/
the imported source/input material is separated by Bundesland under curricula/DE/Gymnasium/input/<STATE>/...
provenance and sourceRef should continue to point to a state-distinguishable source path
the lane-by-lane transfer inventory is tracked in curricula/DE/Gymnasium/input/transfer-manifest.md
abi/ is therefore not treated as a one-off exception, but as part of the general state-scoped retained-asset policy

Current status of this lane:

the target archive scaffold now exists under curricula/DE/Gymnasium/input/
the Hessen non-abi input batches have been transferred into that archive
a first Hessen abi/ small-subject batch has been transferred into that archive
the Hessen abi/Physik bulk has now also been transferred into that archive
the Hessen abi/Mathe bulk has now also been transferred into that archive
the Hessen upper-secondary source-JSON snapshots (39 files) have now also been transferred into that archive
Hessen upper-secondary exam/deploy/adoption helper defaults now resolve against the DE-level abi/ and mapping archives via curricula/DE/Gymnasium/input/HE/retained-asset-registry.json instead of subject-local hardcoded legacy-tree paths
Hessen upper-secondary abi/ task banks, blueprints, source catalogs, and the math release bundle now also use DE-level retained asset paths plus provenance registry references instead of embedding live Gymnasiale_Oberstufe source paths in their operational metadata
the Bavaria subject-source snapshot has now also been transferred into that archive
the optional Bavaria abi/ lane is still undecided and remains out of the current mandatory scope
therefore the currently known mandatory transfer scope is now mirrored; the only open question is whether a Bavaria abi/ lane ever becomes part of scope
for Sek I normalization, the current canonical planning target is a shared G9-aligned year-level grid 5-10; source-side G8 / G9 distinctions remain preserved in provenance and archived inputs

Initial input inventory

State lane	Current source location	Current form	Observed size	Migrated into DE archive	Planned target
`DE-HE` upper-secondary input	`curricula/DE/HE/Kultusministerium/Gymnasiale_Oberstufe/input/`	source PDFs + references	`24` files	`24` files	`curricula/DE/Gymnasium/input/DE-HE/upper-secondary/`

`DE-BY` gymnasium source lane	`curricula/DE/BY/Gymnasium/`	subject JSON source set, no dedicated `input/` tree yet	`45` subject JSON files	`45` files	`curricula/DE/Gymnasium/input/BY/gymnasium/`
`DE-BY` abi lane	not yet present as dedicated canonical migration input lane	reserved	`0` migrated files	`0` files	`curricula/DE/Gymnasium/input/BY/abi/`

Interpretation:

transferred-file counts ignore .gitkeep placeholders in not-yet-filled target directories
Hessen already has explicit source/input and abi trees that can be moved lane by lane.
Bavaria now has a first DE-level separated source snapshot archive, but not yet a dedicated exam lane.
The lower-secondary migration target is currently year-level based, not duration-track based: canonical Sek I should first align to G9-style year buckets 5-10.
The archive scaffold is now in place, and the first HE/BY transfer batches have happened.
The currently known mandatory transfer scope is fully mirrored.
The only remaining lane question is whether Bavaria exam assets must later be added to scope.

19 units at 50%

Formula:

score = (4 * 75 + 19 * 50) / 23
      = 54.35%

Working program score:

55%

Interpretation:

The canonical DE layer is clearly beyond the initial pilot stage.
We are not yet in the decommissioning stage.
The program is currently in the middle of the migration, not near the end.

This score remains useful as a secondary diagnostic for authored canonical coverage. It is no longer the preferred top-line completion headline for the final stretch.

Input-lane interpretation:

canonical graph migration is materially underway
input/source transfer is complete for the currently known mandatory scope, but that does not by itself make any legacy tree deletable

Repo-level deletion readiness

To make deletion progress measurable without pretending that any tree is already removable, we track two separate notions:

gate score: how many deletion preconditions are already in place for a given legacy tree
deletable now: hard yes/no gate; this only becomes yes when the tree can actually be removed from the active repo

Delete-gate model

Tree-level delete progress is estimated with the following weighted gates:

Gate	Weight	Interpretation
Canonical replacement breadth	20%	The legacy tree is broadly represented in the canonical DE layer, not only by a small pilot slice
Runtime default switched	20%	Ordinary learner entry and routing prefer canonical DE views over the legacy tree
Learner cutover path operational	15%	Supported learners can be migrated with deterministic single-learner and/or bulk cutover paths
Retained input/assets mirrored	15%	Input, source, and exam assets that must survive deletion are mirrored into the DE-level state-scoped archive
Audit/provenance survivability	15%	Mappings, provenance, and historical references no longer require the legacy tree to stay in place as active storage
Legacy UI/API detached	15%	The old tree is no longer an active learner-facing operational path and remains, at most, as a temporary compatibility artifact

Scoring rule:

done = full gate weight
partial = half gate weight
no = 0
any tree with at least one open hard gate still has deletable now = no

Tree-by-tree delete matrix

Legacy source tree	Canonical replacement	Runtime default	Cutover path	Input/assets mirrored	Audit/provenance survivability	Legacy UI/API detached	Gate score	Deletable now	Biggest blocker	Next work package
`curricula/DE/HE/Kultusministerium/Gymnasiale_Oberstufe`	done	done	done	done	done	done	100%	yes	none; delete handoff executed and CI now enforces that the tree stays absent	closed; keep the DE-level provenance/archive registries as the surviving audit trail and leave the post-retirement gate in CI
`curricula/DE/HE/Kultusministerium/Gymnasium_9_Mittelstufe`	done	done	done	done	done	done	100%	yes	none; delete handoff executed and CI now enforces the surviving DE-level archive/provenance/mapping lane	closed; keep the DE-level retained-asset, mapping, and provenance registries as the surviving audit trail and leave the post-retirement gate in CI
`curricula/DE/BY/Gymnasium`	done	done	done	done	done	done	100%	yes	none; delete-handoff execution and DE-level audit/reference persistence are in place	closed; keep the DE-level retained-asset, mapping, and provenance registries as the surviving audit trail and leave the post-retirement gate in CI

Current completion-track score

Tracked-tree calculation:

score = (100 + 100 + 100) / 3
      = 100.00%

Working completion-track score:

100%

Interpretation:

this is now the main overall percentage for "how close are we to actually finishing?"
it is now at all tracked-tree closure level, with no remaining legacy-tree delete handoff open
any future movement is now through optional coverage scope extension, not tree delete-handoff
it only reaches 100% when all tracked legacy trees are fully retired from the active repo

Practical conclusion:

The historical rollout program score is around 55%.
The close-out headline score is now 100%.
The input-transfer lane is at 100% for the currently known mandatory scope.
Hard legacy-tree retirement progress is now 100% at tracked-tree granularity, because all three tracked legacy trees have now been removed from the active repo.
Soft delete-gate progress is now visible tree by tree: 100% for Hessen upper-secondary, 100% for Hessen lower-secondary, 100% for Bavaria Gymnasium.

All four statements can be true at the same time, because migration progress, retained-input transfer, delete-gate progress, and actual deletability are different planning dimensions.

Conditions for 100%

We should only set the program to 100% when all of the following are true:

Every tracked migration unit has reached at least legacy_view_retained.
New learners use the canonical DE root by default without needing legacy entry points.
Existing supported learners have a reliable bulk-cutover path and have been migrated where needed.
No runtime-critical API/UI flow still depends on the old legacy trees as active content sources.
Source inputs and exam material that must survive the migration have been transferred into a state-separated DE-level input archive.
Mappings and provenance needed for audit/history are either frozen elsewhere or no longer required.
The legacy source trees can be deleted from the active repo without breaking runtime behavior, QA, or rollback obligations.

Only after step 7 do we convert a unit or source tree from any non-final state into legacy_deleted.

Recommended next planning move

Use this document together with the implementation plan:

keep the implementation plan as the work-package and rollout narrative
keep this file as the single percentage/status view

Recommended update rhythm:

update this file whenever a subtree changes state
use the completion-track score as the primary headline percentage in progress updates
update the program score only from explicit state transitions
update the completion-track score whenever one of the tracked legacy-tree gate scores changes
update the tree-by-tree delete matrix whenever one of the six delete gates materially changes for a legacy source tree
keep docs/dev/canonical-gymnasium-applicability-design.md as the review target for the next widening step of the implemented state-filter architecture
treat checklist R1-R7 and pilot gates A1-A5 in that document as the review gate before widening the reviewed applicability scope further
do not increase the percentage because of "felt progress"

My assessment

Using 100% = old repos deleted is a good idea, but only if we separate:

migration progress
deletion readiness

If we collapse both into one naive percentage too early, the number becomes misleading.

This document therefore uses:

100% as the current completion-track headline score
55% as the current historical migration-program score
100% as the current input-transfer score for the currently known mandatory scope
100% / 100% / 100% as the current delete-gate progress picture for the three tracked legacy trees
100% as the current hard legacy-tree retirement picture, because all three tracked legacy trees have now been removed from the active repo without breaking the verified handoff paths

That is, in my view, the most honest planning representation of the current state.

Mathematics canonical patch log

2026-03-18: J5 early arithmetic and measurement expansion

Approach used:

reuse-first: existing canonical goals were preferred over duplication
first wave limited to early arithmetic plus measurement/area foundations
the broad J5 geometry node remains in place for now; its finer split is deferred to avoid immediate duplicate modeling
new early atoms were scoped initially to DE-BY and documented as candidates for later DE-HE review

Applied changes:

extended the J5 arithmetic cluster with six new early atoms: place value, rounding, basic additive equations, divisibility/prime factorization, powers of ten, and bracket/precedence evaluation
added one new J5 measurement application cluster with three atoms: calculating with quantities, rule of three/scale, and distinguishing perimeter from area
sharpened the existing natural-number foundation goal to mention number-line localization explicitly
tightened early prerequisite flow by making J6 area/volume goals depend on the new J5 quantity/area foundations

Deferred on purpose:

splitting the existing broad J5 geometry atom into finer geometry atoms, because that requires a deliberate refactor to avoid duplicate canonical geometry goals

2026-03-18: J5 M5 Bavaria mapping tranche

Approach used:

mapped only the first high-confidence M5 cases from Bavaria to the canonical graph
preferred exact only where the new or existing canonical atom matched the Bayern source tightly
used partial where the Bayern source remained narrower or broader than the canonical atom
deferred the remaining J5 geometry/process refinements until the broad existing geometry/process nodes are split without duplication

Applied changes:

added a first tranche of explicit DE-BY mappings for J5 arithmetic and measurement/area goals
widened Natürliche Zahlen darstellen, ordnen und mit ihnen rechnen to DE-BY because Bayern J5 now provides direct evidence for that canonical atom

2026-03-18: J5 geometry split and Bavaria geometry mapping

Approach used:

preserved the existing broad J5 geometry goal ID and refactored it from an atomic goal into a geometry cluster to avoid breaking downstream references
split the geometry block only along the five explicit Bavaria M5 2 leaf goals, so the refinement stays source-backed and does not invent duplicate canonical granularity
kept DE-HE applicability on the refined geometry atoms because the refactor only decomposes an already shared early-geometry atom; this narrows structure, not jurisdictional scope
recomputed cluster weights from unique atomic descendants so the J5 lineage stays semantically consistent after the geometry split

Applied changes:

added five new J5 geometry atoms for coordinate-system objects, geometric relations, point sets with distance conditions, angle work, and quadrilateral properties
changed the Bavaria M5 2 cluster mapping from partial to exact
added five exact Bavaria leaf mappings for the new geometry atoms

Deferred on purpose:

no Hessen source-specific leaf mapping review yet for the new geometry atoms
no further J6/J7 prerequisite tightening beyond preserving the existing broad-cluster dependency as the current compatibility edge

2026-03-19: DE-HE prerequisite closure after the J5 geometry split

Approach used:

treated the APV-102 findings as a visibility-closure issue, not as a reason to revert the finer J5 modeling
widened the new J5 measurement tranche to DE-HE, because these atoms now act as explicit prerequisites for already visible Hessen lower-secondary area/volume goals
replaced remaining broad-cluster geometry prerequisites on later visible goals with the finer visible J5 geometry atoms, moving the graph one step closer to atomic prerequisite modeling

Applied changes:

widened Mit Größen rechnen und Ergebnisse deuten, Einfache proportionale Sachaufgaben mit Dreisatz und Maßstab lösen, and Umfang und Flächeninhalt unterscheiden und anwenden plus their J5 cluster to DE-HE
retargeted the affected J6/J7/J8 geometry and area/volume goals from the broad J5 geometry cluster to the new finer geometry atoms

Deferred on purpose:

no separate Hessen source-leaf mapping pass yet for the widened J5 measurement atoms
no validator run in this patch step

2026-03-19: Hessen lower-secondary evidence added for new early-math atoms

Approach used:

treated the remaining APV-102 findings as missing DE-HE evidence in the Hessen lower-secondary mapping layer, not as a canonical-graph failure
added only the smallest mapping tranche needed to close the new J5/J6 prerequisite visibility chain
stayed conservative on match quality: exact only where the Hessen source wording is tight enough, otherwise partial

Applied changes:

added Hessen lower-secondary mappings for the new J5 measurement atoms and their J5 cluster
added Hessen lower-secondary mappings for the new J5 geometry atoms needed by the J6/J7/J8 prerequisite chain, plus the refactored J5 geometry cluster
explicitly anchored the coordinate-system basis atom so the new geometry prerequisites are themselves visible in DE-HE

Deferred on purpose:

no broader Hessen backfill for the rest of the new J5 atom tranche beyond what the current validator findings require
no validator run in this patch step

2026-03-19: Hessen closure switched from duplicate mappings to overrides

Approach used:

reverted the invalid one-to-many Hessen lower-secondary mappings after the backend mapping service exposed the repository invariant that each legacyGoalId may resolve to only one canonical goal
preserved the finer canonical early-math structure and closed DE-HE visibility instead through explicit applicability overrides on the affected canonical atoms
documented the override-backed Hessen bridge in the accepted-warning registry, matching the repository's existing APV-201 pattern for reviewed prerequisite closures

Applied changes:

removed the duplicate Hessen lower-secondary mapping entries that caused GoalMappingService to fail during startup
added extendedData.applicabilityOverrides.jurisdiction = ["DE-HE"] to the new early geometry and measurement atoms that are required by visible Hessen goals but lack a clean one-to-one Hessen source atom
updated the Bavaria math mapping fixture test to the intentionally expanded repository-backed mapping count and the new exact J5 geometry slice

Deferred on purpose:

no broader refactor of repository mapping semantics beyond the current one-legacy-to-one-canonical invariant
no test rerun in this patch step

2026-03-19: M6 rationale numbers patch plan

Approach used:

keep the existing broad J6 goal Rationale Zahlen darstellen und berechnen as the stable public anchor ID and refactor it into a cluster if the finer split is implemented
apply the same reuse-first rule as in J5: reuse existing early arithmetic atoms wherever they already carry the didactic foundation cleanly
add new canonical atoms only for the M6 content that is not yet isolated in the canonical graph at usable granularity
keep the repository mapping invariant in mind: one legacy source goal may map to only one canonical goal; any later jurisdiction widening without clean one-to-one source evidence must be done through applicabilityOverrides, not duplicate mappings

Planned reuse base:

reuse Natürliche Zahlen runden as the rounding prerequisite for decimal fractions
reuse Teilbarkeitsregeln prüfen und Primfaktorzerlegungen angeben as the divisibility and denominator-analysis basis for fraction comparison and decimal conversion
reuse Natürliche und ganze Zahlen addieren und subtrahieren as the additive prerequisite for rational arithmetic
reuse Natürliche und ganze Zahlen multiplizieren und dividieren as the multiplicative prerequisite for rational arithmetic
reuse Klammerterme und Rechenreihenfolge sicher auswerten as the early term-structure basis
reuse Potenzen mit natürlichen Exponenten und Zehnerpotenzen verwenden as the entry point for later extension to rational bases and negative exponents

Planned implementation order:

first refactor the broad J6 rational-number goal into a cluster without changing its stable public ID
then add the eight finer atoms above
then map the Bavaria M6 1.* leaves onto those atoms
only after the Bavaria tranche is stable, review whether any of the new J6 atoms should also be widened to DE-HE through exact evidence or override-backed closure

2026-03-19: J6 rationale numbers expansion

Approach used:

preserved the existing broad J6 rational-number goal ID and refactored it from an atomic goal into a stable cluster, mirroring the J5 geometry strategy
applied the documented reuse-first plan: the new J6 atoms reuse J5 arithmetic prerequisites where possible and only add granularity where the canonical graph did not yet isolate the M6 targets cleanly
scoped the new fine-grained J6 atoms initially to DE-BY, because this patch is still source-backed by the Bavaria M6 slice and no Hessen leaf review has been performed yet
recomputed cluster weights from unique atomic descendants so the J6 and root-level progress semantics remain proportional after the split

Applied changes:

refactored Rationale Zahlen darstellen und berechnen into a cluster
added eight J6 rational-number atoms for fraction concepts, comparison, decimal conversion, number-line ordering, additive arithmetic, multiplicative arithmetic, powers with rational bases, and term evaluation with rational numbers
wired each new atom to existing J5 prerequisites instead of duplicating earlier foundational goals

Deferred on purpose:

no Bavaria mapping tranche yet for the new J6 atoms
no Hessen applicability widening or override review yet for the new J6 atoms
no validator or CI run in this patch step

2026-03-19: J6 Bavaria rational-number mapping tranche

Approach used:

mapped the full Bavaria M6 1.* rational-number leaf set onto the new J6 canonical atoms while keeping the repository's one-legacy-to-one-canonical invariant intact
upgraded the broad Bavaria M6 1 cluster mapping to exact after the J6 rational-number refactor, because the canonical cluster now mirrors the Bavaria block deliberately
used exact only where the Bavaria leaf matches the new canonical atom tightly; left the remaining leaves on partial where the source still mixes adjacent subskills such as conceptual interpretation, strategy choice, or plausibility checks

Applied changes:

added nineteen Bavaria M6 1.* mappings onto the new J6 rational-number atoms
upgraded M6 1 Rationale Zahlen from partial to exact
updated the repository-backed Bavaria mapping fixture to the new mapping count and representative M6 tuples

Deferred on purpose:

no M6 2 or M6 3 Bavaria mapping tranche yet
no Hessen review for the new J6 rational-number atoms yet
no validator or CI run in this patch step

2026-03-19: J6 area and volume expansion plus Bavaria mapping tranche

Approach used:

kept the existing J6 area-volume cluster as the stable public anchor and added only the three geometry atoms that were missing after the reuse-first audit
avoided new cross-jurisdiction prerequisite breaks by not wiring the new DE-BY-only atoms into the existing DE-HE-visible J6 atoms yet
upgraded the broad Bavaria M6 2 cluster mapping to exact after the canonical J6 cluster now mirrors the Bavaria block more faithfully
stayed conservative on the leaf mappings: exact only for the derivation and volume-unit/formula atoms, partial for the broader application goals that still mix adjacent modeling or argumentation aspects

Applied changes:

added three new J6 geometry atoms for deriving area formulas, justifying the cuboid volume formula, and interpreting/converting volume units
sharpened the existing J6 area and solid-calculation descriptions to mention the relevant M6 figure families and unit handling more explicitly
added the Bavaria M6 2.1 and M6 2.2 leaf mappings and updated the repository-backed Bavaria mapping fixture to the new count

Deferred on purpose:

no M6 3 Prozentrechnung, Daten und Diagramme tranche yet
no Hessen review for the new J6 geometry atoms yet
no validator or CI run in this patch step

2026-03-19: J6 percent, data and diagrams expansion plus Bavaria mapping tranche

Approach used:

kept the existing J6 percent/data node as the stable public anchor and refactored it into a cluster instead of replacing the public ID
stayed reuse-first: no late Q3 data goals were reused blindly, because they model broader upper-secondary statistics and would have created a second, phase-skipping data route instead of a clean J6 slice
scoped the five new fine-grained J6 atoms initially to DE-BY only, because this tranche is still backed by the Bavaria M6.3 source block and no Hessen leaf review has been done yet
upgraded the broad Bavaria M6 3 cluster mapping to exact after the canonical J6 cluster now mirrors the source block intentionally
stayed conservative on leaf match quality: the representation/frequency leaf remains partial, while the tighter percentage-text, diagram-critique and arithmetic-mean leaves are mapped exact

Applied changes:

refactored Prozentrechnung anwenden und Daten auswerten into a J6 cluster with five atoms for basic percentage problems, percentage-text interpretation, frequencies, critical diagram reading, and arithmetic mean
wired the new atoms to the existing J5/J6 arithmetic foundations without duplicating earlier number or ratio goals
added the Bavaria M6 3 leaf mappings and updated the repository-backed Bavaria mapping fixture to the new mapping count

Deferred on purpose:

no Hessen review for the new J6 percent/data atoms yet
no further J7/Q3 prerequisite tightening beyond keeping the broad J6 cluster as the compatibility bridge
no validator or CI run in this patch step

2026-03-19: DE-HE closure for new J6 rational-number and percent/data atoms

Approach used:

treated the new APV-102 findings as the same repository constraint we already hit after the J5 split: the broad J6 clusters stayed visible in theory, but their newly introduced children were still DE-BY-only and therefore disappeared in the DE-HE projection
stayed repo-conform by avoiding duplicate Hessen leaf mappings; the backend still requires one legacy source goal per canonical target mapping entry
used the same closure mechanism as before: widen the newly introduced J6 atoms to DE-HE via applicabilityOverrides and record the deliberate override in the accepted-warning registry
kept the fix minimal: no new requires, no additional Hessen mapping tranche, no speculative widening of later J7/Q3 atoms

Applied changes:

widened all eight new J6 rational-number atoms to DE-HE via extendedData.applicabilityOverrides
widened all five new J6 percent/data atoms to DE-HE via extendedData.applicabilityOverrides
added the corresponding APV-201 accepted warnings for the thirteen override-backed J6 atoms

Deferred on purpose:

no Hessen source-specific leaf review yet for these J6 atoms
no attempt to replace the overrides with cleaner Hessen one-to-one evidence in this patch step
no validator or CI run in this patch step

2026-03-19: DE-HE closure for early J5 arithmetic prerequisites after the J6 widening

Approach used:

treated the follow-up APV-102 findings as the next layer of the same prerequisite-visibility chain: the new J6 atoms were now visible in DE-HE, but some of their early J5 arithmetic prerequisites were still DE-BY-only
again stayed repo-conform by avoiding duplicate Hessen mappings and using the existing override-backed closure pattern instead
kept the fix minimal and local to the five missing J5 arithmetic atoms that actually appear in the failing prerequisite list

Applied changes:

widened Stellenwertsystem und Zahlendarstellungen verstehen, Natürliche Zahlen runden, Teilbarkeitsregeln prüfen und Primfaktorzerlegungen angeben, Potenzen mit natürlichen Exponenten und Zehnerpotenzen verwenden, and Klammerterme und Rechenreihenfolge sicher auswerten to DE-HE via extendedData.applicabilityOverrides
added the corresponding APV-201 accepted warnings for those five J5 arithmetic atoms

Deferred on purpose:

no broader Hessen arithmetic leaf review beyond the prerequisite chain needed for the current validator findings
no validator or CI run in this patch step

2026-03-19: J7 Bavaria variable-term mapping tranche

Approach used:

started M7 with the smallest useful Bavaria slice: M7 1 Terme mit Variablen
stayed reuse-first and did not split the canonical J7 algebra anchor yet; instead, the tranche reuses the existing canonical goal Terme mit Variablen aufstellen und umformen wherever the Bayern source already fits that umbrella cleanly enough
reused the existing early power atom for the Bavaria leaf on power laws instead of opening a second near-duplicate algebra target prematurely
stayed conservative on match quality: only the broad M7 1 cluster and the explicit term-transformation leaf were upgraded to exact; the remaining leaves stay partial

Applied changes:

upgraded the Bavaria M7 1 Terme mit Variablen cluster mapping from partial to exact
added nine Bavaria M7 1.1 / M7 1.2 leaf mappings onto the existing canonical J7 algebra anchor and the early power atom
updated the repository-backed Bavaria mapping fixture to the new mapping count

Deferred on purpose:

no canonical J7 algebra refactor yet; the current step is mapping-first
no M7 2 / M7 3 Bavaria tranche yet
no validator or CI run in this patch step

2026-03-19: J7 Bavaria symmetry-and-angle mapping tranche

Approach used:

kept M7 2 Geometrische Figuren: Symmetrie und Winkel on the existing canonical J7 geometry anchor instead of splitting J7 geometry prematurely
upgraded the broad Bavaria M7 2 cluster to exact, because the canonical goal Symmetrie und Winkel begründen already mirrors this corridor closely enough at cluster level
stayed conservative on the leaf mappings: all M7 2.1 and M7 2.2 leaves remain partial, because the Bavaria source mixes concrete construction routines, model references, historical/contextual framing, and multi-step proof language more tightly than the current canonical J7 geometry atom

Applied changes:

upgraded the Bavaria M7 2 cluster mapping from partial to exact
added seven Bavaria M7 2.1 / M7 2.2 leaf mappings onto the existing canonical J7 geometry anchor
updated the repository-backed Bavaria mapping fixture to the new mapping count

Deferred on purpose:

no canonical J7 geometry split yet
no M7 3 or M7 5 Bavaria tranche yet
no validator or CI run in this patch step

2026-03-19: J7 Bavaria linear-equation and percentage tranche

Approach used:

kept M7 3 Lineare Gleichungen und Vertiefung der Prozentrechnung on the existing canonical J7 algebra anchor instead of opening a new split before the current Bavaria slice actually demands it
upgraded the broad Bavaria M7 3 cluster to exact, because the canonical goal Lineare Gleichungen lösen und Prozentrechnung vertiefen already mirrors the corridor directly
stayed conservative on the leaf mappings: the explicit equivalence-transformation leaf is exact, while equation setup, solution interpretation, and the broader applied-percentage leaf remain partial

Applied changes:

upgraded the Bavaria M7 3 cluster mapping from partial to exact
added four Bavaria M7 3 leaf mappings onto the existing canonical J7 algebra/percentage anchor
updated the repository-backed Bavaria mapping fixture to the new mapping count

Deferred on purpose:

no canonical J7 algebra split beyond the existing two anchors
no M7 5 Bavaria triangle/congruence tranche yet
no validator or CI run in this patch step

2026-03-19: J7 Bavaria congruence-and-triangle mapping tranche

Approach used:

kept M7 5 Kongruenz, besondere Dreiecke und Dreieckskonstruktionen on the existing canonical J7 triangle anchor instead of splitting the geometry branch prematurely
upgraded the broad Bavaria M7 5 cluster to exact, because the canonical goal Kongruenz begründen und Dreieckskonstruktionen ausführen already mirrors the corridor directly
stayed conservative on leaf quality: concept introduction, converse logic, dynamic-geometry exploration, Thales work, tangent construction, and application modelling remain partial; the construction-heavy and special-triangle leaves are mapped exact

Applied changes:

upgraded the Bavaria M7 5 cluster mapping from partial to exact
added nine Bavaria M7 5 leaf mappings onto the existing canonical J7 triangle/congruence anchor
updated the repository-backed Bavaria mapping fixture to the new mapping count

Deferred on purpose:

no canonical J7 geometry split beyond the current shared anchors
no M8 Bavaria tranche yet
no validator or CI run in this patch step

2026-03-19: M8 Bavaria function, rational-function, probability and geometry tranche

Approach used:

kept the current canonical J8 corridor intact instead of opening a new split before the Bavaria M8 slice actually forces one
reused the existing cross-phase canonical atom Funktionsbegriff und Darstellungen verstehen for the explicit function-concept leaf in M8 1
kept M8 1 Funktion und Term and M8 2 Lineare Funktionen on conservative partial cluster bridges where the current canonical function corridor is still broader than the Bavaria source wording
upgraded the direct J8 corridor matches for elementary rational functions, fraction terms, Laplace experiments, linear systems, and circle/cylinder work where the canonical pilot already mirrors the Bavaria slice closely enough

Applied changes:

completed the Bavaria M8 mapping tranche across M8 1 to M8 7
upgraded the existing M8 3, M8 4, M8 5, M8 6, and M8 7 cluster bridges from partial to exact
upgraded the existing J8 rational-function and fraction-term leaf bridges from partial to exact where the canonical child atoms already match the Bavaria leaf goals directly
added the missing Bavaria leaf mappings for the introductory function block, the remaining linear-function leaves, the Laplace block, the linear-system block, and the circle/cylinder block
updated the repository-backed Bavaria mapping fixture to the new mapping count

Deferred on purpose:

no new canonical split for the M8 1 or M8 2 function-introduction corridor yet; graph-reading and introductory function-language aspects still lean on partial bridges where the current canonical structure stays coarser than the Bavaria source
no M9 Bavaria audit yet
no validator or CI run in this patch step

2026-03-19: M9 Bavaria quadratics, probability and trigonometry tranche

Approach used:

kept the current canonical J9 corridor intact and reused the existing year-9 anchors instead of opening a new split before the Bavaria M9 slice actually proves a missing atom
treated M9 2 Quadratische Funktionen as a mixed corridor: the leaf level can already attach well to the existing quadratic-function, vertex, quadratic-equation, fraction-equation and linear-system anchors, while the broad Bayern cluster still needs partial umbrella bridges
upgraded the direct J9 corridor matches for connected probability, similarity, power-function, Pythagoras and trigonometry blocks where the canonical pilot already mirrors the Bavaria slice closely enough
stayed conservative on the root and advanced trig leaves where proof, Heron iteration, rationalisation, unit-circle work or broader strategy language exceed the current canonical atom granularity

Applied changes:

completed the Bavaria M9 mapping tranche across M9 1 to M9 7.2
upgraded the existing Bavaria M9 3, M9 4, M9 5, M9 6, M9 7 and M9 7.1 cluster bridges from partial to exact; M9 7.2 stays partial
upgraded the existing leaf bridges for connected probability, power-function graphs, Pythagoras calculations and right-triangle trigonometry where the canonical J9 atoms already match directly
added the missing Bavaria leaf mappings for roots, quadratics, connected probability, similarity, extended power work, Pythagoras and both trigonometry subcorridors
updated the repository-backed Bavaria mapping fixture to the new mapping count

Deferred on purpose:

no new canonical split yet for the broader M9 1 root corridor or the unit-circle/setup part of M9 7.2
no M10 Bavaria audit yet
no validator or CI run in this patch step

2026-03-19: M10 Bavaria exponential, stochastic and trigonometric tranche

Approach used:

reused the existing canonical J10 corridor without opening a new split for exponential growth, stochastic simulations, sinus/cosinus functions or polynomial basics
upgraded M10 1, M10 2, M10 3 and M10 4 to exact at cluster level where the existing J10 anchors already inherit their provenance directly from the same Bavaria source corridors
stayed conservative on most leaf mappings for sinus/cosinus functions, polynomial behaviour and the broad space-geometry continuation, because the current canonical atoms remain coarser than the detailed Bavaria leaf wording
kept M10 5 Fortführung der Raumgeometrie on a deliberate partial bridge, since the current canonical J10 space-geometry atom is still too narrow for the full Bavaria cone/pyramid/sphere corridor

Applied changes:

completed the Bavaria M10 mapping tranche across M10 1 to M10 5
upgraded the existing cluster bridges for M10 1, M10 2, M10 3 and M10 4 from partial to exact
upgraded the direct simulation and tree-rule leaves in M10 2 to exact
added the missing Bavaria leaf mappings for exponential growth, logarithms, sinus/cosinus functions, polynomial basics and the space-geometry continuation
updated the repository-backed Bavaria mapping fixture to the new mapping count

Deferred on purpose:

no new canonical split yet for the bogenmaß/einheitskreis detail in M10 3
no new canonical split yet for the cone/pyramid/sphere-heavy M10 5 corridor
no validator or CI run in this patch step

2026-03-19: Residual Bavaria math partial-gap audit after M10

Audit result:

after the M5 to M10 tranches, the Bavaria math landscape now has only 11 remaining partial bridges inside the year-5-to-year-10 corridor
in addition, 17 intermediate Bavaria section nodes remain unmapped; these are broad subsection wrappers rather than missing leaf coverage

Residual partial bridges grouped by type:

acceptable broad bridges for now:
M5 3 Natürliche und ganze Zahlen – Multiplikation und Division -> Natürliche und ganze Zahlen multiplizieren und dividieren
M5 4 Größen und ihre Einheiten -> Größen und Einheiten vergleichen und umrechnen
M7 4 Kenngrößen von Daten -> Kenngrößen von Daten bestimmen und interpretieren
M8 1 Funktion und Term -> Funktionsgrundlagen (Sek I)
M8 2 Lineare Funktionen -> Funktionsgrundlagen (Sek I)
likely real canonical-structure gaps:
M9 1 Quadratwurzeln -> current canonical atom is too narrow for the full Bavaria corridor with irrationality, Heron iteration, root-term algebra and rationalisation
M9 2 / M9 2.1 / M9 2.2 -> the current quadratic corridor is distributed over several atoms, but still lacks a cleaner shared quadratic cluster for exact subsection anchoring
M9 7.2 Sinus- und Kosinussatz -> unit-circle and setup aspects still exceed the current Sinus- und Kosinussatz nutzen atom
M10 5 Fortführung der Raumgeometrie -> the current J10 space-geometry atom is too coarse for the Bavaria cone/pyramid/sphere continuation

Unmapped intermediate subsection nodes:

M5:
M5 1.1
M5 1.2
M5 3.1
M5 3.2
M5 4.1
M5 4.2
M6:
M6 1.1
M6 1.2
M6 1.3
M6 1.4
M6 1.5
M6 2.1
M6 2.2
M7:
M7 1.1
M7 1.2
M7 2.1
M7 2.2

Interpretation:

the remaining subsection-node gaps are mainly mapping hygiene and do not indicate missing Bavaria leaf coverage
the next canonical-modeling work should focus on the four real gap zones instead of broad cleanup

Recommended next patch order:

M10 5 Fortführung der Raumgeometrie
M9 7.2 Sinus- und Kosinussatz plus unit-circle preparation
M9 1 Quadratwurzeln
only afterwards: subsection-node mapping cleanup for M5 to M7

2026-03-19: J10 space-geometry split for Bavaria M10 5

Approach used:

refactored the existing canonical J10 space-geometry atom 6248bbd7-c7e8-4f91-b3dc-de885cf5abce into a cluster while retaining its ID as the stable corridor anchor
reused the existing circle/cylinder, pythagoras, right-triangle trigonometry and sinus/cosinus-law prerequisites instead of duplicating earlier geometry content
introduced only the six missing J10 atoms that the Bavaria M10 5 corridor actually isolates: bodies and nets, solids of revolution, cone surface area, pyramid/cone volumes, sphere formulas and applied space-geometry modeling
kept the new J10 atoms voorlopig on DE-BY only; no Hessen closure decision was folded into this patch step

Applied changes:

split the canonical J10 space-geometry corridor into one retained cluster plus six new atomic descendants
remapped the Bavaria M10 5 cluster and all six leaf goals onto the refined canonical J10 space-geometry atoms
upgraded the Bavaria M10 5 cluster bridge from partial to exact now that the canonical corridor mirrors the Bavaria subsection directly
updated the repository-backed Bavaria math mapping fixture to the new J10 space-geometry targets

Deferred on purpose:

no DE-HE applicability review yet for the six new J10 space-geometry atoms
no validator or CI run in this patch step

2026-03-19: Hessen closure for the new J10 space-geometry split

Approach used:

kept the J10 space-geometry split itself unchanged and closed only the missing Hessen visibility chain
avoided new Hessen one-to-many mappings and used the established math closure mechanism via extendedData.applicabilityOverrides
opened exactly the six new J10 space-geometry atoms for DE-HE, because the broad retained cluster 6248bbd7-c7e8-4f91-b3dc-de885cf5abce is already referenced by visible Hessen goals

Applied changes:

added DE-HE applicability overrides to all six new J10 space-geometry atoms
added the corresponding APV-201 accepted-warning entries for the Hessen math prerequisite bridge rationale

Deferred on purpose:

no new Hessen leaf-mapping tranche for these J10 atoms
no validator or CI run in this patch step

2026-03-19: J9 trigonometry split for Bavaria M9 7.2

Approach used:

kept the existing J9 trigonometry bridge cluster 219ce079-6bfd-4827-8b66-5dd199e44686 and refactored only the broad child 0cefa694-636e-4c4b-abff-3ac3750dca18
split the old mixed atom into exactly the two Bavaria M9 7.2 strands that had been entangled before: unit-circle based sign/orientation work and the proof/application corridor for sinus- and cosine-law work
reused the existing right-triangle trigonometry atom as the shared prerequisite instead of opening a wider trigonometric dependency fan
closed Hessen visibility immediately for the two new J9 atoms via the established override-backed prerequisite bridge, because the retained HE corridor already depends on the broad J9 trig bridge

Applied changes:

refactored 0cefa694-636e-4c4b-abff-3ac3750dca18 from atomic goal to J9 trig cluster
added the two new canonical J9 atoms for unit-circle sine/cosine values in degree measure and for proving/applying the sine and cosine laws
upgraded the Bavaria M9 7.2 cluster bridge from partial to exact and remapped both Bavaria leaf goals to the new canonical atoms
updated the Bavaria mapping fixture and added the two matching APV-201 accepted-warning entries for the Hessen prerequisite bridge

Deferred on purpose:

no new Hessen legacy leaf-mapping tranche for these J9 atoms
no validator or CI run in this patch step

2026-03-19: J9 square-roots split for Bavaria M9 1

Approach used:

refactored the old broad J9 square-root atom 8a0b0baf-c7e6-43df-a470-f56050ecaa46 into a retained cluster so downstream references stay stable
split the corridor into the five Bavaria M9 1 strands that were previously collapsed: square-root basics, irrationality/reals, Heron iteration, radical arithmetic, and rationalisation/partial extraction
tightened the sequencing for Quadratische Gleichungen loesen by replacing the former broad cluster prerequisite with the two new root atoms that are actually needed there
closed Hessen visibility immediately for the new J9 root atoms via the established override-backed prerequisite bridge

Applied changes:

turned the old J9 square-root atom into a five-child cluster
upgraded the Bavaria M9 1 cluster bridge from partial to exact and remapped all five Bavaria leaf goals to dedicated canonical J9 root atoms
rewired the canonical quadratic-equations goal away from the broad root cluster to the relevant fine-grained root prerequisites
updated the Bavaria mapping fixture and added the five matching APV-201 accepted-warning entries for the Hessen prerequisite bridge

Deferred on purpose:

no new Hessen legacy leaf-mapping tranche for these J9 root atoms
no validator or CI run in this patch step

2026-03-19: J9 quadratics split for Bavaria M9 2

Approach used:

repurposed the old broad quadratic-function atom 5a9702f4-7e4d-457d-b98c-f0bafcd1e386 into a retained J9 quadratics cluster so downstream references stay stable
separated the Bavaria M9 2 corridor into a foundations branch and an applications branch instead of keeping subsection mappings on a single coarse atom
reused the existing canonical atoms for solving quadratic equations, vertex work, linear systems and rational equations wherever they already matched cleanly
introduced only the missing atoms for parameter effects, graph-property reading, form switching, deriving quadratic functions from conditions, and modelling with quadratic functions
opened the new J9 quadratic clusters and atoms for DE-HE via the established override-backed prerequisite bridge

Applied changes:

turned 5a9702f4-7e4d-457d-b98c-f0bafcd1e386 into a J9 quadratics cluster with a foundations and an applications subtree
upgraded the Bavaria cluster mappings M9 2, M9 2.1 and M9 2.2 from partial to exact
remapped the previously broad Bavaria leaf bridges in M9 2 to dedicated canonical quadratic atoms
rewired the J9 year anchor so the quadratic corridor hangs under the retained quadratics cluster instead of duplicating the old subclusters directly
updated the Bavaria mapping fixture and added the matching APV-201 accepted-warning entries for the Hessen prerequisite bridge

Deferred on purpose:

no new Hessen legacy leaf-mapping tranche for the new J9 quadratic atoms
no validator or CI run in this patch step

2026-03-19: J9 quadratics inheritance fix after validator feedback

Approach used:

kept the new J9 quadratics split intact and corrected only the placement of the didactic prerequisite
removed the foundation prerequisite from the broad J9 applications cluster because that cluster intentionally reuses the older J8 atom 797ee047-b8dd-45cf-880e-98571a56c690 for rational equations
attached the foundation prerequisite only to the J9-specific modelling atom, where the later-phase dependency is didactically justified

Applied changes:

cleared the direct requires edge from the J9 applications cluster 0d4a6f56-2f87-4c39-98ab-5f13f5cbdd40
added the same prerequisite explicitly to the J9 modelling atom a7ccb7a9-6fb0-4e2d-b6e0-6420cc5ae0bf

Deferred on purpose:

no validator or CI run in this patch step

2026-03-19: Bavaria math residual audit for Jgst. 5-10 after the M5-M10 wave

Audit scope:

Bavaria source corridor restricted to the descendants of Jahrgangsstufe 5 through Jahrgangsstufe 10
excludes Bavaria M11 to M13, because those were not part of the current migration tranche

Observed state:

corridor size: 246 Bavaria source goals
remaining partial mappings: 103
remaining unmapped source goals: 31
of those unmapped goals:
17 are subsection clusters
14 are atomic goals

Interpretation:

the residual set is no longer dominated by missing year-level coverage; the year clusters are already mapped and the remaining work is mostly local cleanup
the 17 unmapped subsection clusters are primarily mapping-hygiene debt, not canonical blind spots:
M5 1.1, M5 1.2, M5 3.1, M5 3.2, M5 4.1, M5 4.2
M6 1.1 through M6 1.5
M6 2.1, M6 2.2
M7 1.1, M7 1.2, M7 2.1, M7 2.2
the largest remaining partial hot clusters are broad canonical anchors rather than newly missing Bavaria coverage:
5d17ebb4-4e27-4f9c-8d0b-3520f34b2e11 trigonometrische Funktionen (7 partial leaves)
8da730f1-8947-498d-9e78-7fb20b00a994 J7-Geometrieanker (7)
fd860da9-73ba-47cd-a1a8-452424915a80 J7-Algebra/Termanker (7)
f0a49da2-018b-4cda-adbd-27047b610a0f Kongruenz-/Konstruktionsanker (6)
1f89d69e-ead1-424b-8221-fae37fdea2bc J6-Fläche/Volumen-Anwendungen (5)

Residual gap judgment:

strongest remaining canonical gap candidate:
M7 4 Kenngrößen von Daten
still only a broad cluster bridge, while the Bavaria source still leaves the three atomic strands unmapped:
- median / boxplots
- quartiles / spread
- extracting information from boxplots
plausible secondary gap candidates, but lower priority than M7 4:
early counting-principle atom in M5 3.1
basic multiplicative equation atom in M5 3.1
most other remaining atomic partial bridges are acceptable breadth mismatches for now, not evidence of missing canonical structure

Recommended order from this audit:

close the real content gap around M7 4 descriptive statistics
then do the subsection-cluster cleanup for M5 to M7
only afterwards revisit the broad but acceptable partial bridges if a stricter exactness target is needed

2026-03-19: Reuse-first patch plan for Bavaria M7 4 descriptive statistics

Reuse baseline already present in canonical math:

91571d3f-3651-4477-ba21-320fc4077453 Absolute und relative Häufigkeiten bestimmen und darstellen
existing J6 percentage/data corridor already also contains atoms for:
diagram interpretation
arithmetic mean
current Bavaria M7 4 umbrella still lands only partially on the broad canonical bridge 075ef99c-7f84-48b5-97f1-4e28c7d78f95

Source-side residual structure in Bavaria M7 4:

one already partially mapped leaf bundles absolute/relative frequencies together with early aggregate use
three source leaves still expose the actual remaining gap more clearly:
median use
quartiles / spread / boxplots
extracting information from boxplots and known descriptive measures

Patch recommendation:

refactor 075ef99c-7f84-48b5-97f1-4e28c7d78f95 from broad atom to retained cluster
reuse the existing atoms for:
absolute and relative frequencies
arithmetic mean
generic diagram interpretation where it already fits
add only the missing descriptive-statistics atoms:
Median bestimmen und mit dem arithmetischen Mittel vergleichen
Spannweite und Quartile bestimmen und Boxplots erstellen
Datenverteilungen mithilfe von Kenngrößen und Boxplots vergleichen und deuten

Expected mapping consequence:

the mixed Bavaria leaf that currently combines frequencies with early aggregate use will likely remain partial, because the source bundles more than one fine-grained canonical atom and the mapping layer is intentionally one-to-one
the median / quartile / boxplot corridor should become cleanly mappable without opening duplicate canonical data goals

Decision rationale:

this is the smallest patch that closes the last clearly visible Sek-I data-analysis gap
it avoids inventing a duplicate “descriptive statistics basics” atom just to force one exact mapping for a bundled Bavaria leaf
it keeps the canonical graph aligned with the established rule: exactness where the source isolates a didactic strand cleanly, partial where the source intentionally bundles multiple strands

2026-03-19: J7 descriptive-statistics split for Bavaria M7 4

Approach used:

refactored the broad J7 data-indicators atom 075ef99c-7f84-48b5-97f1-4e28c7d78f95 into a retained cluster so downstream references stay stable
kept the already reusable arithmetic-mean atom outside the new cluster and used it as an explicit prerequisite instead of duplicating a J7 copy of the same competence
introduced only the three missing descriptive-statistics atoms that Bavaria M7 4 actually isolates cleanly:
median versus arithmetic mean
quartiles / range / boxplots
comparing data distributions with indicators and boxplots
closed Hessen visibility immediately for the three new J7 atoms via the established override-backed prerequisite bridge

Applied changes:

turned 075ef99c-7f84-48b5-97f1-4e28c7d78f95 into a three-child J7 data-indicators cluster
upgraded the Bavaria M7 4 cluster bridge from partial to exact
mapped the three Bavaria M7 4 leaves exactly to the new canonical J7 descriptive-statistics atoms
updated the Bavaria mapping fixture and added the three matching APV-201 accepted-warning entries for the Hessen prerequisite bridge

Deferred on purpose:

no subsection-cluster cleanup for M5 to M7 in this patch step
no validator or CI run in this patch step

2026-03-19: Bavaria M5-M7 subsection-cluster cleanup

Approach used:

treated the remaining unmapped subsection nodes in M5 to M7 as mapping-hygiene work, not as a new canonical-authoring wave
mapped each subsection cluster to the closest existing canonical corridor that its already mapped children were predominantly using
kept these bridges deliberately partial, because these subsection clusters still bundle multiple finer canonical atoms and the mapping layer stays one-to-one

Applied changes:

added subsection-cluster mappings for:
M5 1.1, M5 1.2, M5 3.1, M5 3.2, M5 4.1, M5 4.2
M6 1.1 to M6 1.5
M6 2.1, M6 2.2
M7 1.1, M7 1.2, M7 2.1, M7 2.2
updated the Bavaria mapping fixture to the new repository-backed mapping size

Resulting interpretation:

the remaining residual Bavaria Sek-I math gaps are now concentrated much more clearly in true leaf-level breadth mismatches instead of administrative subsection omissions
this makes the next residual audit materially sharper, because the unmapped set is no longer inflated by missing subsection wrappers

Deferred on purpose:

no new canonical atoms in this cleanup step
no validator or CI run in this patch step

2026-03-19: Updated residual Bavaria Sek-I math audit after subsection cleanup

Scope used:

Bavaria Gymnasium mathematics source corridor Jahrgangsstufe 5 to Jahrgangsstufe 10
source file: curricula/DE/Gymnasium/input/BY/gymnasium/Mathematik.json
mapping file: curricula/DE/Gymnasium/mapping/DE-BY/gymnasium/bavaria_math_to_canonical_math.json

Current repository-backed counts for the reviewed Sek-I corridor:

total source goals in scope: 246
mapped goals: 235
of those mapped:
116 exact
119 partial
remaining unmapped goals: 11

Remaining unmapped goals are now concentrated in a single early corridor rather than spread across later-year canonical gaps.

Residual unmapped set:

M5 arithmetic / early-process leaves only:
natural-number infinity / very large-number orientation
checking integer statements with counterexamples
arithmetic-advantage leaves around commutativity / associativity / distributivity
one early counting-principle leaf
one multiplication/division-equation leaf
one term-structure leaf for whole-number mixed operations
two problem-solving / heuristic / application leaves with whole numbers
one benchmark-based estimation leaf

Residual partial hotspots by size:

8da730f1-8947-498d-9e78-7fb20b00a994 J7 symmetry / angle geometry corridor: 9
fd860da9-73ba-47cd-a1a8-452424915a80 J7 algebra corridor: 9
5d17ebb4-4e27-4f9c-8d0b-3520f34b2e11 J9 trigonometric-functions corridor: 7
1f89d69e-ead1-424b-8221-fae37fdea2bc J6/J10 volume-surface corridor: 6
f0a49da2-018b-4cda-adbd-27047b610a0f J7 congruence / Thales corridor: 6

Residual-gap judgment:

the remaining large partial groups are mostly acceptable breadth mismatches, not evidence of another urgent canonical modeling hole
after the J7/J9/J10 splits already completed, the sharpest remaining uncovered content is no longer in later-year function or geometry corridors
the real residual blind spot is now the early Bavaria M5 arithmetic/process layer, because all 11 unmapped goals sit there

Recommended next patch wave:

close the remaining M5 unmapped arithmetic/process leaves
keep the broad J7/J9 partial corridors as reviewed breadth mismatches unless a stricter exactness target is explicitly needed
only after the M5 closure, decide whether any of the large partial hotspots merit another canonical split at all

2026-03-19: Reuse-first patch plan for residual Bavaria M5 arithmetic/process closure

Residual source leaves still unmapped in the Bavaria Sek-I scope:

natural-number infinity / naming very large numbers
checking integer statements with counterexamples
arithmetic-advantage leaves for addition/subtraction and multiplication/division
early counting-principle leaf
multiplication/division-equation leaf
mixed-operation term-structure leaf
heuristic problem-solving / application leaves with whole numbers
benchmark-based estimation leaf

High-confidence reuse targets already present in the canonical J5 corridor:

624764d6-becd-5f9b-ada3-0d4f9d143073 Stellenwertsystem und Zahlendarstellungen verstehen
fe07241a-b779-5f35-a82d-7aa51ae74f42 Natürliche Zahlen runden
4b67bed9-06da-40b2-a306-24e9e7dfd390 early whole-number / integer number corridor
cafd6520-c4af-4109-9863-cc49ba6fad4d early multiplication/division corridor
5d1decb2-b01b-5c85-88fc-9fc255ff9776 Klammerterme und Rechenreihenfolge sicher auswerten
ca9093cd-9ccf-5fb4-9dd8-bf4f92af4e70 simple proportional / measure-context problem solving

Likely true residual canonical gaps:

Natürliche Zahlen als unbegrenzt fortsetzbar verstehen und große Zahlbezeichnungen sicher verwenden
Aussagen über ganze Zahlen prüfen und mit Gegenbeispielen widerlegen
Einfache Multiplikations- und Divisionsgleichungen durch Umkehroperationen lösen
Rechenvorteile mit Kommutativ-, Assoziativ- und Distributivgesetz gezielt nutzen
Problemstellungen mit ganzen Zahlen heuristisch lösen und Lösungswege dokumentieren
Größen in Sachsituationen mithilfe von Bezugsgrößen schätzen

Open review candidate before authoring a new atom:

Zählprinzip in einfachen realitätsnahen Kontexten systematisch anwenden

Reason:

this leaf may deserve a small early counting atom
but first it should be checked against the existing stochastic / combinatorial entry corridor to avoid inventing a duplicate precursor if a reusable canonical node already exists

Planned patch order:

verify whether the early counting-principle leaf can reuse an existing canonical atom
add only the six clearly missing J5 arithmetic/process atoms listed above
remap the 11 remaining Bavaria M5 leaves
keep any still bundled source leaf on partial if it genuinely mixes more than one of the new fine-grained strands

Expected result:

the Bavaria Sek-I pilot should then have no obvious unmapped M5 blind spot left
remaining residual debt would mostly be deliberate partial breadth mismatches rather than missing canonical authoring

2026-03-19: Residual Bavaria M5 arithmetic/process closure

Approach used:

kept the existing J5 arithmetic and measurement clusters as retained anchors instead of opening another large structural refactor
reused the existing term-structure atom 5d1decb2-b01b-5c85-88fc-9fc255ff9776 for the previously unmapped mixed-operation leaf
added only the genuinely missing early J5 atoms for:
unbounded natural-number understanding and large-number naming
checking integer statements with counterexamples
arithmetic advantages from commutative / associative laws
basic multiplicative equations via inverse operations
simple counting principles in contextual situations
heuristic whole-number problem solving with documented solution paths
benchmark-based estimation in quantity contexts
closed Hessen visibility for these new prerequisite atoms directly via the established override-backed bridge

Applied changes:

expanded the retained J5 arithmetic cluster 8dd5199b-f614-4ebd-8819-b5ff37326524 with six new early-process atoms and recomputed its weight
expanded the retained J5 measurement-application cluster b40bebc2-91e3-5aac-916d-43247ee08d09 with one new estimation atom and recomputed its weight
updated the J5 year anchor weight accordingly
mapped the 11 previously unmapped Bavaria M5 leaves:
10 to the newly added J5 atoms
1 (4d77f5fc-016f-527e-a1c3-44797aead19a) to the already existing term-structure atom
updated the repository-backed Bavaria mapping fixture and added the corresponding Hessen APV-201 accepted-warning entries

Resulting interpretation:

the Bavaria Sek-I pilot no longer has an obvious unmapped M5 blind spot
remaining residual debt now sits predominantly in deliberate partial breadth mismatches rather than in missing canonical J5 authoring

2026-03-20: Validation pass after Bavaria M5 arithmetic/process closure

Validation used:

./run_ci.sh

Validation result:

./run_ci.sh passed after the residual Bavaria M5 closure commit
the repository-backed Bavaria Sek-I mathematics review corridor Jahrgangsstufe 5-10 is now fully mapped:
total source goals in scope: 246
mapped goals: 246
of those mapped:
- 126 exact
- 120 partial
remaining unmapped goals: 0

Interpretation:

the Bavaria Sek-I mathematics pilot no longer has an unmapped reviewed-source gap in the J5-J10 corridor
the next substantive work should therefore not be another residual Bavaria M5 authoring patch
the next widening step should move back to applicability-review scope using docs/dev/canonical-gymnasium-applicability-design.md and its R1-R7 / A1-A5 review gates

2026-03-20: Bavaria function-value applicability debt reduced from `APV-201` to `APV-202`

Approach used:

reviewed the two remaining Bavaria math function-value visibility cases that still relied on explicit DE-BY applicability overrides
replaced each override-backed visibility path with the narrowest reviewed Bavaria source bridge that still fits as a partial mapping
kept the canonical goal semantics unchanged; only the Bavaria review basis and warning family changed

Applied changes:

remapped Bavaria source leaf 32a0f358-c1e9-5663-b8cf-67789355387c from the broad function-concept atom to Funktionswerte aus Graphen ablesen
remapped Bavaria source leaf 7ee3da1c-1f20-5038-9828-ab74e0e1e49f from the broad J7 variable-term corridor to Funktionswerte berechnen
removed the explicit extendedData.applicabilityOverrides.jurisdiction = ["DE-BY"] entries from the two canonical function-value goals
converted the two accepted Bavaria math findings from APV-201 to APV-202 in the accepted-warning registry

Validation used:

npm run validate:view-filters
cd backend && GRADLE_USER_HOME=/home/enpasos/projects/skillpilot/backend/.gradle-ci ./gradlew clean check --no-daemon --console=plain

Validation result:

validate:view-filters still passes and now classifies the two reviewed Bavaria function-value cases as accepted APV-202 findings instead of explicit-override APV-201 findings
the repository-backed Bavaria math mapping fixture test passes with the reviewed remap tuples

Interpretation:

reviewed Bavaria math no longer depends on Bavaria-specific explicit applicability overrides for the canonical function-value pair
the residual Bavaria math debt on this slice is now partial-bridge review debt, not override debt

2026-03-20: Bavaria music partial-bridge debt reduced by two exact upgrades

Approach used:

reviewed the smallest remaining non-math APV-202 slice in the Bavaria pilot set
kept the canonical music structure stable and only sharpened two E-phase atom descriptions so they match both the Hessen source wording and the reviewed Bavaria leaf wording
upgraded the two Bavaria music bridges to exact where the reviewed canonical wording now covers the source goals tightly enough

Applied changes:

refined Grundformen erkennen into Satzstruktur und Grundformen erkennen
refined Proben organisieren into Gestaltungs- und Probenprozesse organisieren
upgraded the Bavaria music mappings for 4e9fd039-4532-5337-b06a-083eca009613 and 8a850d1b-f325-5a40-bac1-0c06517c902c from partial to exact
removed the two corresponding Bavaria music APV-202 entries from the accepted-warning registry

Validation used:

npm run validate:view-filters
./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'

Validation result:

validate:view-filters still passes with 0 errors, 25 active warnings, and 186 accepted warnings
accepted reviewed warnings dropped from 193 to 191
the repository-backed mapping fixture test still passes

Interpretation:

the reviewed Bavaria music pilot no longer carries any accepted APV-202 debt on the currently reviewed surface
the next applicability-review candidate should now come from a larger remaining APV-202 lane such as Bavaria Latin, Bavaria economics, Bavaria politics/economics, Bavaria biology, or Bavaria history

2026-03-20: Bavaria Latin partial-bridge debt cleared by five exact upgrades

Approach used:

reviewed the smallest remaining language-side APV-202 lane in the Bavaria pilot set after music
kept the canonical Latin structure stable but replaced five placeholder-like atom labels with source-aligned operational wording
upgraded only those Bavaria bridges whose reviewed source leaves now fit the canonical targets one-to-one

Applied changes:

refined Grammatik festigen into Lektürespezifische Grammatikphänomene analysieren
refined Grundinterpretation into Originaltexte grundlegend interpretieren
refined Kontext/Autoren into Autoren, Werke und Kontexte einordnen
refined Interpretation into Kommunikations- und Ethikfragen interpretieren
refined Vergleich/Transfer into Rhetorische Texte vergleichen und Transfer leisten
upgraded the five Bavaria Latin mappings for 192be448-1888-5f15-a100-38c58f74dd58, 4b3bef2c-a27d-5334-b2cf-53548ab5a438, ec10b9a4-fc64-5e8f-a19b-45a187c39017, 35793922-864f-5739-a56c-42ad6df8410a, and b952bb09-3ff6-573c-9a41-0575345e4e5a from partial to exact
removed the five corresponding Bavaria Latin APV-202 entries from the accepted-warning registry

Validation result:

validate:view-filters still passes with 0 errors, 25 active warnings, and 186 accepted warnings
accepted reviewed warnings dropped from 191 to 186
the repository-backed mapping fixture test still passes

Interpretation:

the reviewed Bavaria Latin pilot no longer carries any accepted APV-202 debt on the currently reviewed surface
the next applicability-review candidate should now come from a larger remaining APV-202 lane such as Bavaria economics, Bavaria politics/economics, Bavaria biology, or Bavaria history

2026-03-20: Bavaria physics override-backed applicability debt reduced from six cases to four

Approach used:

reviewed the smallest remaining accepted-warning lane after the Latin pass and found that Bavaria physics was still dominated by explicit DE-BY override debt rather than ordinary partial-bridge debt
preferred reviewed Bavaria source bridges over canonical re-authoring: two previously unmapped Bavaria mechanics leaves were promoted to partial bridges, while the earlier attempt to repoint broader reviewed cluster bridges was discarded because it changed planned-goal behavior in backend integration tests
kept the canonical physics goal semantics unchanged and reduced only the Bavaria visibility mechanism

Applied changes:

added Bavaria partial bridges from a114f68b-91d5-593e-9d5b-d31d3240bf19 to Kräfte und Trägheit qualitativ erklären and from c75cb2dd-c143-5537-82aa-4676a1148c71 to Newtons 1. Axiom (Trägheitsprinzip)
removed the explicit extendedData.applicabilityOverrides.jurisdiction = ["DE-BY"] entries from the two canonical physics goals Kräfte und Trägheit qualitativ erklären and Newtons 1. Axiom (Trägheitsprinzip)
converted the two corresponding Bavaria physics findings from APV-201 to APV-202 in the accepted-warning registry
updated the repository-backed Bavaria physics mapping fixture to the new mapping size and reviewed tuples

Validation result:

validate:view-filters still passes with 0 errors, 25 active warnings, and 186 accepted warnings
accepted reviewed warnings stay at 186, but Bavaria physics now carries 4 accepted APV-201 cases and 2 accepted APV-202 cases instead of 6 accepted APV-201 cases
the repository-backed mapping fixture test, the learner-planning regression slice, and full ./run_ci.sh pass with the retained broader cluster bridges

Interpretation:

reviewed Bavaria physics no longer depends on explicit Bavaria-specific applicability overrides for two of the six previously override-backed cases without changing learner-facing planning behavior
the next sharp follow-up on this lane is to resolve or reclassify the four remaining Bavaria physics override-backed goals: Freier Fall experimentell untersuchen, Newtons 3. Axiom (Wechselwirkungsprinzip), Mechanische Energieformen qualitativ unterscheiden, and Kinetische Energie

2026-03-20: Bavaria physics Newton-III override retired without changing Hessen topic totals

Approach used:

targeted the remaining Bavaria physics case that already had a reviewed exact source leaf on the Newton-III application side, but still depended on an explicit Bavaria-specific applicability override on the broader conceptual node
kept the public canonical Newton-III id stable by turning Newtons 3. Axiom (Wechselwirkungsprinzip) into a small cluster and adding a dedicated Hessen-only concept atom underneath it
rejected the simpler single-child cluster rewrite after it reduced Hessen champion totals by one; the final split preserves the previous Hessen topic-count surface while still letting Bavaria visibility derive from the reviewed application leaf

Applied changes:

converted canonical goal 5a1b3cb2-c0e6-4372-9c57-f33675cffc9b (Newtons 3. Axiom (Wechselwirkungsprinzip)) from an override-backed atomic goal into a cluster containing the new Hessen-only concept atom ad984bb6-e225-432a-952d-d83cda40b7f8 (Newtons 3. Axiom formulieren und erläutern) and the existing reviewed Bavaria-visible application atom a0aaedcb-41f8-4891-af77-a69a76b8c10d (Newtons 3. Axiom anwenden)
removed the redundant direct containment of a0aaedcb-41f8-4891-af77-a69a76b8c10d from Newtons Axiome und Inertialsysteme so the new Newton-III substructure stays cleanly nested
removed the explicit extendedData.applicabilityOverrides.jurisdiction = ["DE-BY"] entry from 5a1b3cb2-c0e6-4372-9c57-f33675cffc9b
removed the now-obsolete accepted Bavaria physics APV-201 entry for 5a1b3cb2-c0e6-4372-9c57-f33675cffc9b

graph validation, the focused backend regression slice, and full ./run_ci.sh all pass

Interpretation:

reviewed Bavaria physics no longer needs a Bavaria-specific override for the canonical Newton-III concept node, and Hessen learner-facing topic totals stay stable after the structural split
the remaining Bavaria physics override-backed cases are now Freier Fall experimentell untersuchen, Mechanische Energieformen qualitativ unterscheiden, and Kinetische Energie

2026-03-20: Bavaria physics free-fall override retired while preserving motion-frontier behavior

Approach used:

targeted the remaining Bavaria physics free-fall case because it already sat next to reviewed Bavaria-visible motion-analysis and acceleration atoms
kept the public canonical free-fall id stable by turning Freier Fall experimentell untersuchen into a small cluster and adding one Hessen-only experimental evaluation leaf underneath it
rejected the broader variant that also nested Bewegungen mit Diagrammen untersuchen under the free-fall container after it displaced expected motion-frontier suggestions in cutover and cross-subject backend tests; the final structure keeps diagram analysis independent and uses only the acceleration side for Bavaria visibility

Applied changes:

converted canonical goal 230345f3-c360-4963-b390-ab94e3e2c864 (Freier Fall experimentell untersuchen) from an override-backed atomic goal into a cluster containing the Bavaria-visible acceleration atom e4b38061-1f28-43ad-8371-a3e7c0e81856 and the new Hessen-only atom 09029573-864f-40ca-bf8a-cee7bf6dcb73 (Fallbeschleunigung aus Messdaten bestimmen)
preserved Bewegungen mit Diagrammen untersuchen as an independent sibling goal and kept it only as a prerequisite of the new Hessen-only free-fall atom
removed the explicit extendedData.applicabilityOverrides.jurisdiction = ["DE-BY"] entry from 230345f3-c360-4963-b390-ab94e3e2c864
removed the now-obsolete accepted Bavaria physics APV-201 entry for 230345f3-c360-4963-b390-ab94e3e2c864

graph validation, the focused backend regression slice, and full ./run_ci.sh all pass after the narrowed final structure

Interpretation:

reviewed Bavaria physics no longer needs a Bavaria-specific override for the canonical free-fall container, and the expected Hessen/cross-subject motion frontier behavior stays intact
the remaining Bavaria physics override-backed cases are now Mechanische Energieformen qualitativ unterscheiden and Kinetische Energie

2026-03-20: Bavaria physics Sek-I energy-forms override converted into reviewed partial-bridge debt

Approach used:

inspected the last Bavaria physics energy corridor and avoided a broader canonical energy split for now because the remaining Kinetische Energie case still lacks a comparably clean reviewed source leaf
kept the existing reviewed exact Bavaria energy rows unchanged and instead promoted one previously unmapped Bavaria heat-lehre source leaf to a partial bridge for the Sek-I bridge goal Mechanische Energieformen qualitativ unterscheiden
preferred this narrower bridge because the Bavaria source text explicitly assumes prior knowledge of mechanische Energieformen, making it a defensible reviewed visibility bridge without shifting the upper-secondary mechanical-energy mapping surface

Applied changes:

added a new Bavaria partial bridge from b0a2ec7a-df5f-5bf3-b8eb-f3668c25917d to canonical goal 722857cf-f327-5740-8151-64eb92195ec8 (Mechanische Energieformen qualitativ unterscheiden)
removed the explicit extendedData.applicabilityOverrides.jurisdiction = ["DE-BY"] entry from canonical goal 722857cf-f327-5740-8151-64eb92195ec8
converted the accepted Bavaria physics finding for 722857cf-f327-5740-8151-64eb92195ec8 from APV-201 to APV-202

the repository-backed mapping fixture test, the learner-planning regression slice, and full ./run_ci.sh pass with the narrower reviewed bridge

Interpretation:

reviewed Bavaria physics no longer needs a Bavaria-specific override for the Sek-I qualitative energy-forms bridge; Bavaria visibility now comes from reviewed source mappings alone
the last remaining Bavaria physics override-backed case is now Kinetische Energie

2026-03-20: Bavaria physics kinetic-energy override reviewed and retained as the final physics exception

Approach used:

reviewed the remaining Bavaria physics energy corridor after the Sek-I energy-forms pass, including the lower-secondary energy, heat-lehre, charged-particle, and spaceflight source leaves that still mention energy or kinetic-energy-adjacent concepts
rejected additional partial bridges because the clean Bavaria energy source rows are already committed to Mechanische Energie, Potenzielle Energie, Energieerhaltung, and Arbeit, while the remaining unmapped Bavaria leaves mention kinetic energy only indirectly or in different conceptual settings
preferred an explicit retained-override decision over a weak source bridge or a broader canonical energy refactor that would overclaim Bavaria coverage for the formula-focused canonical atom Kinetische Energie

Applied changes:

kept canonical goal 7eeff2de-6015-49a6-a96e-a488d886dc9f (Kinetische Energie) and the reviewed Bavaria physics mapping surface unchanged
tightened the accepted-warning rationale for 7eeff2de-6015-49a6-a96e-a488d886dc9f so the last remaining Bavaria physics APV-201 case is documented as an intentional retained override rather than generic closure debt
logged the reviewed retention decision in this migration status file

Validation used:

Validation result:

validate:view-filters still passes with 0 errors, 25 active warnings, and 184 accepted warnings
full ./run_ci.sh passes
Bavaria physics remains at 1 accepted APV-201 case plus 3 accepted APV-202 cases; this is now the reviewed end state of the current physics applicability lane

Interpretation:

Bavaria physics has no further clean override-retirement candidate on the currently reviewed source surface; the remaining kinetic-energy case should stay accepted until a better source-aligned split or source atom exists
the next applicability-review target should move outside physics; the smallest remaining reviewed APV-202 lanes are currently Bavaria Informatik, Bavaria Wirtschaft, Bavaria Deutsch, and Bavaria Griechisch with 8 accepted partial-bridge cases each

2026-03-20: Bavaria Greek early E-phase bridge upgraded from partial to exact

Approach used:

reviewed the smallest remaining non-physics language lane and found that the Bavaria Greek debt was concentrated in one regular Gr10 corridor with eight one-to-one source-to-canonical mappings
identified the main problem as generic canonical placeholder wording rather than missing structure: the canonical E-phase Greek strip still used broad template-style labels such as Lektüre E-Phase Griechisch and Projekt/Reflexion E-Phase Griechisch, while the Bavaria source already isolated concrete reading, vocabulary, syntax, translation, analysis, position-taking, oral presentation, and productive-reception tasks
kept ids and didactic sequencing stable, but rewrote the eight canonical atoms into source-facing task wording so the reviewed Bavaria rows could be promoted from partial to exact

Applied changes:

rewrote the eight Bavaria-visible canonical E-phase Greek atoms in DE_DEU_S_GYM_CANONICAL_GRIECHISCH.de.json from generic placeholder phrasing to source-aligned task wording:
Originaltexte kursorisch lesen und Inhalte erfassen
Lektürebegleitenden Wortschatz gezielt sichern
Komplexe syntaktische Strukturen untersuchen
Komplexe griechische Strukturen übersetzen
Originaltexte sprachlich analysieren
Zu griechisch formulierten Inhalten Stellung nehmen
Lehrbuchtexte verständnisgeleitet vortragen

2026-03-20: Bavaria Informatik grammar-source remap removes one more partial-bridge case without adding new canonical nodes

What changed:

the Bavaria source goal a2db53a1-4449-5d78-825e-81ba1fa07c02 no longer maps partially into the Hessen-only canonical atom Ableitungen prüfen (3e3264d6-8cf8-55f9-b085-1aa4a7865476)
instead, that source goal now maps exactly to the already-existing canonical atom Grammatiken entwickeln (fbd4561a-573e-5f8c-b363-338ee9774b5c) in bavaria_informatics_to_canonical_informatics.json, because the reviewed Bavaria wording is about defining grammars with EBNF and syntax diagrams rather than checking derivations

the Bavaria-visible follow-on canonical goal Sprachen klassifizieren (18691bbb-b996-57a6-9f91-8ff54acabbce) now requires Grammatiken entwickeln instead of Ableitungen prüfen, preserving the reviewed Bavaria Q3.1 route without widening the Hessen-only derivation atom

Interpretation:

Bavaria Informatik drops from 5 to 4 reviewed APV-202 cases
the remaining Bavaria Informatik debt is now concentrated in the broader automata, algorithm, and higher-data-structure corridors rather than the Inf9 object-programming strip

2026-03-20: Bavaria Informatik search-corridor split removes the Q1 algorithm partial bridge

What changed:

the Bavaria source goal 4d042307-060f-5b86-a435-ddc6a58ccbf5 no longer maps partially into the Hessen-shaped canonical atom Suchalgorithmen implementieren (7c2d2a49-c4a4-51b6-be7b-e8791f82af5a)
instead, canonical goal 7c2d2a49-c4a4-51b6-be7b-e8791f82af5a was turned into a small mixed-state cluster in DE_DEU_S_GYM_CANONICAL_INFORMATIK.de.json
the Hessen semantics now live on the new DE-HE leaf 2a87fb3c-394b-47b4-bda2-58c5f1403475 (Suchalgorithmen implementieren), and the Bavaria wording now lives on the new DE-BY leaf c62c529f-3732-4c66-a8e4-6d91ed2285d0 (Algorithmen auf Listen und Feldern entwickeln und implementieren)
the Hessen mapping in hessen_informatics_upper_secondary_to_canonical_informatics.json was repointed from the former shared atom to the new Hessen-only leaf
the Bavaria mapping in bavaria_informatics_to_canonical_informatics.json was upgraded from partial to exact against the new Bavaria-only leaf
the Hessen follow-on canonical goals Einfache Sorten nutzen and Hashing und Kollisionen now require the new Hessen-only leaf instead of the mixed-state cluster, so the old Hessen prerequisite chain is preserved
the obsolete accepted warning for canonical goal 7c2d2a49-c4a4-51b6-be7b-e8791f82af5a was removed from applicability-accepted-warnings.json

2026-03-20: Bavaria Informatik automata split removes the two non-regular-language partial bridges

What changed:

the Bavaria source goals a19cd533-ac0c-57a9-8098-093d1918a605 and c7623044-bb7b-5375-9a65-27932a296834 no longer map partially into the Hessen-only pushdown-automata atoms Kellerautomaten und Grammatiken verknüpfen (200ff84a-3158-5d2f-b065-36b77ea99ef1) and Deterministische Kellerautomaten entwickeln (36725b54-fd0c-5b24-bf2f-399491562718)
instead, canonical goal 9b497287-aa68-5bb1-974f-5be11dd11ae2 was turned into a small mixed-state cluster in DE_DEU_S_GYM_CANONICAL_INFORMATIK.de.json
the Hessen semantics now live on the new DE-HE leaf 10a3b2a3-8c1c-4dfb-9d48-8f67f2c0004d (Grenzen endlicher Automaten erkennen), and the Bavaria wording now lives on the new DE-BY leaf e7fb0601-4207-4bd8-8c40-1f544590b855 (Nichtreguläre Sprachen als Grenze endlicher Automaten erläutern)
the Hessen mapping in hessen_informatics_upper_secondary_to_canonical_informatics.json was repointed from the former shared atom to the new Hessen-only leaf
the two Bavaria mappings in bavaria_informatics_to_canonical_informatics.json were upgraded from partial to exact against the new Bavaria-only leaf
the canonical cluster Q3.3 Kellerautomat (52ab668f-87b6-5661-af2a-3dc38557dcf6) and the two old pushdown-automata atoms 36725b54-fd0c-5b24-bf2f-399491562718 and 200ff84a-3158-5d2f-b065-36b77ea99ef1 now carry DE-HE applicability only again
the Bavaria-visible canonical cluster Q3.4 Turingmaschine (49e18e35-3a6d-53f7-842f-4dc9e39c745a) now requires the shared finite-automata-limits cluster 9b497287-aa68-5bb1-974f-5be11dd11ae2 instead of the Hessen-only pushdown-automata cluster, preserving Bavaria visibility without widening the Hessen-only PDA corridor
the obsolete accepted warnings for canonical goals 200ff84a-3158-5d2f-b065-36b77ea99ef1 and 36725b54-fd0c-5b24-bf2f-399491562718 were removed from applicability-accepted-warnings.json

Bavaria Informatik drops from 3 to 1 reviewed APV-202 case
the remaining Bavaria Informatik debt is now the higher-data-structure list/stack corridor around Stapeln und Warteschlangen nutzen (898684c0-027c-5fc8-8448-6f33fc26d5b4)

2026-03-20: Bavaria Informatik list-operations split closes the last reviewed APV-202 case

What changed:

the Bavaria source goal 340f8522-7e39-5361-8886-4c8767a76af2 no longer maps partially into the Hessen-shaped canonical atom Stapeln und Warteschlangen nutzen (898684c0-027c-5fc8-8448-6f33fc26d5b4)
instead, canonical goal 898684c0-027c-5fc8-8448-6f33fc26d5b4 was turned into a small mixed-state cluster in DE_DEU_S_GYM_CANONICAL_INFORMATIK.de.json
the Hessen semantics now live on the new DE-HE leaf 8179e63e-764c-4348-a5f1-f738fb2cc04e (Stapeln und Warteschlangen nutzen), and the Bavaria wording now lives on the new DE-BY leaf 0bfd9371-8a7b-407c-9244-fe6ecbe2b56d (Operationen auf einfach verketteten Listen entwickeln)
the Hessen mapping in hessen_informatics_upper_secondary_to_canonical_informatics.json was repointed from the former shared atom to the new Hessen-only leaf
the Bavaria mapping in bavaria_informatics_to_canonical_informatics.json was upgraded from partial to exact against the new Bavaria-only leaf
the shared canonical goal Binäre Bäume bearbeiten (56a88f2f-cc47-5e1d-b7d9-1822a66e3b91) continues to require the mixed-state cluster, so the shared higher-data-structure route stays visible without widening the Hessen-only stack/queue leaf
the obsolete accepted warning for canonical goal 898684c0-027c-5fc8-8448-6f33fc26d5b4 was removed from applicability-accepted-warnings.json

Interpretation:

Bavaria Informatik drops from 1 to 0 reviewed APV-202 cases
the reviewed Bavaria Informatik applicability lane is now closed; the next cut should move to another subject

2026-03-20: Steering refocus to Mathematics-first DE expansion

What changed:

after the current Hessen/Bavaria close-out wave, the preferred expansion path is no longer broader subject coverage on the same two-state base
the next convergence track should instead add further Bundeslaender to canonical Gymnasium Mathematik, one state at a time and one didactically closed corridor at a time
the concrete execution note now lives in docs/dev/canonical-gymnasium-math-de-expansion-plan.md
DE-NW is the preferred next onboarding target because the existing input lane already points to both a Gymnasium G9 Sek-I mathematics curriculum and an upper-secondary mathematics curriculum, while still exposing the current blocker clearly: only README-level source references are present so far

Interpretation:

the next executable task is NRW mathematics source import plus DE-NW mapping-lane setup
further optional non-math widening should pause until at least one third-state mathematics corridor has been onboarded on the shared canonical math spine

2026-03-20: NRW mathematics source import completes Stage A of the Math-first DE expansion

What changed:

the first non-Hessen, non-Bavaria mathematics source import step is now complete for DE-NW
the official NRW Gymnasium mathematics source PDFs are now archived locally under curricula/DE/Gymnasium/input/NW/
Sek I mathematics now lives at curricula/DE/Gymnasium/input/NW/lower-secondary/g9_m_klp_3401_2019_06_23_0.pdf
upper-secondary mathematics now lives at curricula/DE/Gymnasium/input/NW/upper-secondary/gost_klp_m_2023_06_07.pdf
source provenance is documented beside each file in lower-secondary/references.md and upper-secondary/references.md
the NRW input README now reflects the archived-file state instead of only pointing to external curriculum links

Interpretation:

Stage A from canonical-gymnasium-math-de-expansion-plan.md is complete for NRW mathematics
the next executable NRW task is Stage B/C: keep the planned DE-NW mapping lanes, then register NRW mathematics source landscapes and provenance material before starting the first reviewed function-corridor mappings

2026-03-20: NRW mathematics mapping-lane setup completes Stage B without premature provenance activation

What changed:

the first real DE-NW canonical math mapping fixtures now exist at curricula/DE/Gymnasium/mapping/DE-NW/lower-secondary/nrw_math_lower_secondary_to_canonical_math.json and curricula/DE/Gymnasium/mapping/DE-NW/upper-secondary/nrw_math_upper_secondary_to_canonical_math.json
both fixtures are repository-backed and test-covered, but intentionally still empty (0 mappings)
stable NRW source-landscape IDs are now reserved for the future source snapshots:
lower-secondary math: c862423f-d0ac-4a65-8ad2-9a6e560313a8
upper-secondary math: d3a068ca-90c6-4d7f-ab6b-4d8b43085cb1
the reservation and activation rule now live in curricula/DE/Gymnasium/provenance/nrw-math-onboarding.md
the shared provenance README now states the operational rule explicitly: do not add planned state-onboarding entries to the active shared registries before a real archived source-landscape snapshot with stable source goal IDs exists

Interpretation:

Stage B from canonical-gymnasium-math-de-expansion-plan.md is now complete for NRW mathematics
the next NRW task is no longer generic mapping-lane setup; it is a concrete source-snapshot import problem
active source-landscape-registry.json, source-goal-membership-registry.json, and source-goal-closure-registry.json updates should wait until the first NRW source-landscape JSON exists

2026-03-20: NRW mathematics pilot source snapshots complete Stage C and activate shared provenance

What changed:

the first NRW mathematics source snapshots now exist under curricula/DE/Gymnasium/input/NW/lower-secondary/source-json/DE_NRW_S_GYM_1_MATHEMATIK.de.json.snapshot and curricula/DE/Gymnasium/input/NW/upper-secondary/source-json/DE_NRW_S_GYM_2_MATHEMATIK.de.json.snapshot
both source snapshots are intentionally narrow pilot subsets focused on the first shared functions corridor, not yet full NRW subject imports
the shared provenance registries now actively expose both NRW source landscapes plus their imported goal memberships and atomic closures
the NRW archive lane now also contains a short structure note at curricula/DE/Gymnasium/input/NW/math-structure-note.md
the DE-NW mapping-lane READMEs now point at active source snapshots instead of a deferred provenance state

Interpretation:

Stage C from canonical-gymnasium-math-de-expansion-plan.md is now complete for NRW mathematics
the next executable NRW task is the first reviewed canonical math mapping cut on the shared function spine
there is no longer a provenance blocker for DE-NW mathematics onboarding; the remaining blocker is reviewed corridor authoring quality

2026-03-20: DE-NW becomes an active canonical Gymnasium filter, but NRW function authoring exposes a prerequisite-snapshot blocker

What changed:

the applicability compiler now treats DE-NW as a supported Gymnasium jurisdiction next to DE-HE and DE-BY
the canonical Gymnasium overview now exposes DE-NW / Nordrhein-Westfalen as a real root filter option
backend and frontend filter plumbing now recognize DE-NW in the shared canonical Gymnasium root instead of silently treating NRW as an unknown filter value
the first two real NRW canonical math mappings now exist:
lower-secondary source goal 779925c9-038c-4905-b049-de083db123ac
upper-secondary source goal 8fe81d64-ff44-46cf-964b-3312ca6dfa28
both NRW source goals map exactly to the shared canonical motivation atom 71cec9fb-3751-4d61-8b34-c5adbbf6e5f2 (Warum Mathematik? – Denken, Muster & Zukunft)
compiled applicability was reapplied afterwards, so the canonical math root now genuinely exposes a first DE-NW slice instead of only a speculative filter placeholder
the same DE-NW activation also reaches the canonical overview root and the existing cross-subject physics entry corridor through already-modeled mathematics-to-physics dependencies

Validation used:

./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest' --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest'
npm run validate:view-filters
./run_ci.sh

Validation result:

npm run validate:view-filters now reports 0 errors, 3 warnings, 160 accepted warnings
the focused backend regression slice passed
full ./run_ci.sh passed after the DE-NW activation step
the new DE-NW projection is now active with:
mathematics: 2 visible goals
physics: 3 visible goals
overview: 1 visible goal
no new NRW-specific applicability warnings were introduced by this exact-bridge step

Interpretation:

this step successfully turns DE-NW from a planned onboarding lane into a real third-state canonical filter
the first attempted NRW function review also made the generic blocker explicit: the current narrow NRW pilot snapshots do not yet contain the prerequisite strip that the shared canonical function atoms depend on
the next NRW task is therefore not another blind function mapping pass
instead, widen the NRW source snapshots first by the missing function prerequisites (Zuordnungen, proportionality / early linear foundations, and the still-missing arithmetic or equation prerequisites), then return to the first reviewed function-atom mappings

2026-03-20: NRW Sek-I source snapshot widened by the prerequisite strip for first function mappings

What changed:

the NRW Sek-I source snapshot now no longer starts directly at imported function atoms
instead, the same sourceLandscapeId now also contains the first prerequisite strip needed before shared canonical function mappings become plausible:
Erprobungsstufe quantity-relation and rule-of-three goals
first-stage rational-number, variable, term, and linear-equation goals
first-stage mapping-characterization goals that sit immediately in front of the imported linear-function atoms
the shared provenance registries source-goal-membership-registry.json and source-goal-closure-registry.json were widened in place for the same NRW lower-secondary landscape
the NRW math structure note and onboarding note now treat this lower-secondary prerequisite strip as part of the active NRW pilot surface

Validation used:

./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest'
npm run validate:graph
npm run validate:view-filters
./run_ci.sh

Validation result:

the widened NRW lower-secondary source snapshot loads cleanly and remains backed by the shared DE-level provenance registries
canonical graph validation still passes
npm run validate:view-filters remains at 0 errors, 3 warnings, 160 accepted warnings
full ./run_ci.sh passed after the source-snapshot widening step

Interpretation:

the NRW blocker has moved one layer deeper: the source side is now broad enough for a real first review of Zuordnungen analysieren and Funktionsbegriff und Darstellungen verstehen
the next NRW task is now the first reviewed lower-secondary function mapping pass, not more source widening by default

2026-03-20: NRW lower-secondary exact bridges complete Stage D2 on the shared function spine

What changed:

the first reviewed NRW lower-secondary function mapping pass is now complete on top of the already-live motivation bridge
the NRW lower-secondary mapping fixture now carries 7 exact mappings in total:
the shared motivation atom
three lower-secondary arithmetic anchors
the first rational-number ordering anchor
Zuordnungen analysieren
Funktionsbegriff und Darstellungen verstehen
to make the function-side bridges valid, the NRW Sek-I source snapshot was widened one more time by three explicit arithmetic atoms in the Erprobungsstufe strip:
natural numbers represent / order / calculate
natural and whole numbers add / subtract
natural and whole numbers multiply / divide
compiled applicability was reapplied afterwards, so the new DE-NW reach is now persisted in canonical mathematics instead of living only in temporary reports

Validation used:

./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
npm run validate:graph
npm run apply:applicability
npm run validate:view-filters

Validation result:

the repository-backed NRW lower-secondary mapping fixture now parses cleanly with all 7 exact rows
canonical graph validation still passes after the added NRW arithmetic and function bridges
npm run validate:view-filters is back at 0 errors, 3 warnings, 160 accepted warnings after persisting applicability
full ./run_ci.sh passed after the NRW Stage-D2 step

Interpretation:

the hidden-prerequisite blocker for the first shared NRW function corridor is gone; Zuordnungen analysieren and Funktionsbegriff und Darstellungen verstehen are now genuinely active for DE-NW
the next NRW task is no longer more prerequisite widening by default
instead, stay on the existing 2.4.1 Funktionen slice and review the next follow-on atoms in order:
Funktionswerte berechnen
Funktionswerte aus Graphen ablesen
the first linear-parameter atom if the source alignment is strong enough

2026-03-20: NRW function-value follow-on atoms reach DE-NW through reviewed partial bridges

What changed:

the broad NRW Stage-1 source expectation around function representations is now modeled as a small source-aligned subcluster under 5cf6e2fd-ce79-4a7e-b21f-fd5f68d97edc
that split yields one exact NRW representation leaf for the shared canonical representation atom and two additional NRW leaves that back the immediate follow-on canonical value atoms:
c65ecabf-d00b-4e2d-99ae-b64692325ffb (Funktionswerte berechnen)
a8c42ee9-2898-4247-819f-c235032ac78a (Funktionswerte aus Graphen ablesen)
both new NRW bridges are intentionally partial, not exact
the reason is the same one already accepted in Bavaria: the NRW source wording clearly covers representation work with tables and graphs, but does not isolate separate one-to-one source atoms for direct value calculation and graph-based value reading
the accepted-warning registry now records these two DE-NW-specific APV-202 decisions explicitly instead of leaving them as active drift

Validation used:

./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
npm run apply:applicability
npm run validate:view-filters

Validation result:

the repository-backed NRW lower-secondary mapping fixture now parses cleanly with 9 rows
npm run validate:view-filters remains at 0 errors, 3 warnings, 162 accepted warnings after persisting applicability
full ./run_ci.sh passed after the NRW follow-on bridge step

Interpretation:

DE-NW now reaches the first shared function-concept atom plus the two immediate function-value follow-on atoms without reopening the hidden-prerequisite problem
this is a reviewed retention of source breadth mismatch, not a claim that NRW already exposes cleaner exact atoms here
the next NRW task should stay in the same corridor and decide whether the linear-parameter pair can be handled more cleanly:
0159a2d5-baca-4652-8515-350f7b853267 against the graph-side parameter atom
ec6f0c55-6008-4792-b315-09918e7f7248 against the contextual parameter atom

2026-03-20: NRW linear-parameter corridor reaches DE-NW with reviewed prerequisite-backed partial bridges

What changed:

the NRW lower-secondary math mapping lane now carries 12 rows instead of 9
the two reviewed Stage-1 parameter atoms are now bridged into the shared canonical line/parameter corridor:
0159a2d5-baca-4652-8515-350f7b853267 -> af3d6bff-c5fb-4ec6-a9f0-c0be09fc9186 (Lineare Funktionen beschreiben) as partial
ec6f0c55-6008-4792-b315-09918e7f7248 -> 2d75fd3f-c68b-4a11-89ae-19a30fefc47a (Parameter linearer Funktionen deuten) as partial
the attempted af3d6bff-c5fb-4ec6-a9f0-c0be09fc9186 bridge surfaced a real hidden-prerequisite gap for c1f50bcc-7848-4e49-b9de-0ec030cc6bca (Proportionale Zuordnungen nutzen)
instead of accepting a new override, the NRW Erprobungsstufe source atom d54b396e-653f-48c6-966d-cada189a84aa (Dreisatzverfahren zur Loesung von Sachproblemen anwenden) now backs that canonical prerequisite as a reviewed partial bridge
the accepted-warning registry now records these three DE-NW-specific APV-202 decisions explicitly:
c1f50bcc-7848-4e49-b9de-0ec030cc6bca
af3d6bff-c5fb-4ec6-a9f0-c0be09fc9186

npm run apply:applicability persisted the expected canonical math applicability update without new validation errors
npm run validate:view-filters remains at 0 errors, 3 warnings, 165 accepted warnings
full ./run_ci.sh passed after the NRW linear-parameter bridge step

Interpretation:

DE-NW now reaches the shared lower-secondary line foundation plus the first linear-parameter interpretation atom without introducing any new applicability overrides
this is still reviewed source-breadth retention, not a claim that NRW exposes one-to-one canonical atoms for proportional mappings or linear-parameter semantics
the next NRW decision point has moved beyond the Stage-1 linear corridor:
either stay in lower-secondary functions and review the first Stage-2 function-class atom
or switch deliberately to widening the upper-secondary NRW math snapshot before adding more canonical bridges

2026-03-20: NRW reaches the first effective Stage-2 quadratic bridge through the graph-parameter atom

What changed:

the NRW lower-secondary math mapping lane now carries 13 rows instead of 12
the first effective NRW Stage-2 bridge is not the broad class-distinction atom itself, but the more concrete graph-parameter source goal f02c5ec8-cb34-410a-bf5e-fb331b0a2080
that NRW source atom now maps as a reviewed partial bridge to 5bced7dc-6557-4af1-9e70-d87f850d3b7f (Parameter quadratischer Funktionen in Scheitelpunktform deuten)
this in turn activates the first NRW-visible J9 quadratic child and pulls the shared quadratic clusters into DE-NW through compiled child-union:
d4a9fc20-d1be-46e7-86e9-2bf8d7a9cc40 (Quadratische Funktionen und Gleichungen grundlegend untersuchen)
5a9702f4-7e4d-457d-b98c-f0bafcd1e386 (Quadratische Funktionen beschreiben und anwenden)
the accepted-warning registry now records the new DE-NW-specific APV-202 for 5bced7dc-6557-4af1-9e70-d87f850d3b7f
the earlier exploratory idea to bridge the broad NRW class-distinction atom directly to the quadratic cluster was not kept; the effective retained step is the atomic graph-parameter bridge because cluster applicability compiles from visible children

Validation used:

./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
npm run apply:applicability
npm run validate:view-filters
./run_ci.sh

Validation result:

npm run validate:view-filters remains at 0 errors, 3 warnings, 166 accepted warnings
full ./run_ci.sh passed after the NRW Stage-2 quadratic bridge step

Interpretation:

DE-NW now reaches the first real lower-secondary quadratic atom in the shared canonical graph, not just Stage-1 function foundations
the NRW Stage-2 lane is therefore active, but still only at its entry point
the next NRW task should stay in this quadratic corridor and make the broad class-distinction decision explicit:
either review cfadb2dd-a25f-4f83-bbf6-6df00bdd091d against the next quadratic follow-on atom if the alignment is defensible
or introduce a small NRW Stage-2 source split before attempting more canonical quadratic bridges

2026-03-20: NRW extends the Stage-2 quadratic lane to graph-property reading without a source split

What changed:

the NRW lower-secondary math mapping lane now carries 14 rows instead of 13
the broad NRW class-distinction source atom cfadb2dd-a25f-4f83-bbf6-6df00bdd091d now maps as a reviewed partial bridge to e0c3359d-7d8a-4d01-a25e-a8cd5ebce90e (Eigenschaften quadratischer Funktionen aus Graphen ablesen)
this makes the second visible NRW quadratic foundation leaf available in the shared canonical J9 corridor without adding or splitting NRW source nodes

npm run validate:view-filters remains at 0 errors, 3 warnings, 167 accepted warnings
full ./run_ci.sh passed after the NRW Stage-2 graph-property step

Interpretation:

the earlier Stage-2 decision is now closed: for this slice, the broad NRW class-distinction atom was defensible enough as a direct reviewed partial bridge, so no source split was needed
DE-NW now reaches both the first parameter leaf and the next graph-property leaf in the retained J9 quadratic foundations corridor
the next NRW task should stay in Stage 2, but move from quadratic foundations into the application/growth atom:
either review 890a6667-7cec-41ac-be6b-c7ed6121b0d7 against the first quadratic application node if the alignment is defensible
or introduce a small NRW Stage-2 source split before attempting that application bridge

2026-03-20: NRW activates the first quadratic application bridge through the broad growth atom

What changed:

the NRW lower-secondary math mapping lane now carries 15 rows instead of 14
the broad NRW Stage-2 growth/application source atom 890a6667-7cec-41ac-be6b-c7ed6121b0d7 now maps as a reviewed partial bridge to a7ccb7a9-6fb0-4e2d-b6e0-6420cc5ae0bf (Quadratische Funktionen in Anwendungen modellieren und loesen)
this activates the first NRW-visible quadratic application leaf and pulls the shared quadratic application cluster 0d4a6f56-2f87-4c39-98ab-5f13f5cbdd40 into DE-NW

Interpretation:

the second Stage-2 decision is now also closed: for this slice, the broad NRW growth/application atom was defensible enough as a direct reviewed partial bridge, so no NRW source split was needed
DE-NW now reaches both the quadratic foundations branch and the first quadratic applications branch in the shared J9 corridor
the next NRW task should move to upper-secondary breadth instead of forcing more lower-secondary Stage-2 splits:
keep the reviewed lower-secondary NRW Stage-2 bridges stable
then widen the NRW upper-secondary math lane beyond the current motivation-only exact bridge

2026-03-20: NRW reaches the first upper-secondary analysis entry leaf beyond motivation

What changed:

the NRW upper-secondary math mapping lane now carries 2 rows instead of 1
the first real NRW upper-secondary analysis bridge is not yet the broad derivative bundle, but the more conservative E-phase source atom 0c1195ec-efe3-4d68-9219-e46a807c802d (Mittlere und lokale Aenderungsraten berechnen und deuten)
that NRW source atom now maps as a reviewed partial bridge to ae20183e-92b5-5521-b8e0-9a8662cf51f5 (Mittlere Änderungsrate berechnen und deuten)
this activates the first NRW-visible upper-secondary analysis leaf and pulls the shared canonical derivative-entry cluster a115f984-2628-54fb-9702-9511e460d684 (Einführung in den Ableitungsbegriff) into DE-NW

npm run validate:view-filters remains at 0 errors, 3 warnings, 169 accepted warnings
full ./run_ci.sh passed after the NRW upper-secondary E-phase entry step

Interpretation:

NRW upper-secondary math is now active on the shared canonical analysis spine beyond the motivation anchor
the broad NRW derivative/monotonicity source atom is still intentionally untouched; the retained step is the narrower change-rate bridge because it is the cleanest first E-phase entry
the next NRW task should stay in the upper-secondary E.2 corridor and make the derivative-entry decision explicit:
either review 3d1a8d83-27a4-4a0d-b8e0-c738f274d4bd against the next derivative-entry atom if the alignment is defensible
or introduce a small NRW upper-secondary source split before attempting broader derivative and monotonicity bridges

2026-03-20: NRW reaches the next E.2 derivative-entry leaf through a reviewed prerequisite bridge

What changed:

the NRW upper-secondary math mapping lane now carries 3 rows instead of 2
the previously deferred broad NRW source atom 3d1a8d83-27a4-4a0d-b8e0-c738f274d4bd (Ableitung als Tangentensteigung und Monotonieinstrument deuten) is now reused once as a reviewed partial bridge to 2143e9e8-b176-545b-b2fa-91bbb6c8cf5c (Momentane Änderungsrate qualitativ verstehen)
this exposed a real hidden-prerequisite edge in the shared canonical derivative-entry route: 2143e9e8-b176-545b-b2fa-91bbb6c8cf5c requires b42bdfcc-3db7-5697-8b3e-69e50962ca86 (Grenzwerte des Differenzenquotienten bestimmen)
instead of forcing a weaker second mapping immediately, the prerequisite atom now carries a reviewed retained DE-NW applicability override in the canonical math graph
the accepted-warning registry now records the NRW-specific follow-on decisions explicitly:
APV-202 for 2143e9e8-b176-545b-b2fa-91bbb6c8cf5c

npm run validate:view-filters remains at 0 errors, 3 warnings, 171 accepted warnings

Interpretation:

NRW upper-secondary math now reaches the next shared E.2 derivative-entry leaf beyond the first average-rate bridge
the reused broad NRW derivative/monotonicity source atom is now proven usable for one more conservative follow-on step, but only with an explicit retained prerequisite bridge
the next NRW task should stay in the same upper-secondary E.2 corridor and decide whether the same broad source atom can defensibly support one more follow-on derivative leaf, or whether a small NRW source split is now the cleaner move before broader derivative/monotonicity authoring

2026-03-20: NRW upper-secondary E.2 gains a source-split point-derivative bridge without reopening hidden-prerequisite drift

What changed:

the broad NRW upper-secondary source atom 3d1a8d83-27a4-4a0d-b8e0-c738f274d4bd is no longer treated as an indivisible atomic leaf inside the archived source snapshot
the NRW upper-secondary source snapshot now keeps 3d1a8d83-27a4-4a0d-b8e0-c738f274d4bd as a retained corridor cluster and splits it into two child atoms:
c3791879-8901-443a-ac91-bf9cd712b38e for pointwise derivative interpretation as local rate and tangent slope
c876c75b-dcc4-426e-be0f-15698add835d for monotonicity and derivative-function interpretation
the existing reviewed partial bridge from the retained corridor cluster 3d1a8d83-27a4-4a0d-b8e0-c738f274d4bd to 2143e9e8-b176-545b-b2fa-91bbb6c8cf5c stays in place
the new NRW child atom c3791879-8901-443a-ac91-bf9cd712b38e now maps as a reviewed partial bridge to b1dcc191-d046-50de-984a-ee5c17157628 (Ableitung als Steigung im Punkt deuten)
the canonical prerequisite cut was tightened at the same time:
b1dcc191-d046-50de-984a-ee5c17157628 now depends only on b42bdfcc-3db7-5697-8b3e-69e50962ca86
bb979dbd-b080-432c-8cf1-067ba6eff381 (Tangentengleichungen und Steigungswinkel bestimmen) now requires 858113c5-e53b-57bb-b01f-ba95c3ddcb6f directly, so tangent-equation calculation stays gated by derivative-rule fluency
the shared NRW source-goal membership and closure registries were widened in place for the split source snapshot, and the backend registry expectation was updated accordingly

npm run validate:view-filters remains at 0 errors, 3 warnings, 172 accepted warnings
full ./run_ci.sh passed after the NRW upper-secondary source-split point-derivative step

Interpretation:

NRW upper-secondary math now reaches the next shared point-derivative interpretation leaf without forcing another applicability override
the retained NRW source split proved to be the cleaner move than stacking further broad-source mappings on one legacy goal ID
the next NRW task should stay on the second split child c876c75b-dcc4-426e-be0f-15698add835d and decide whether it can defensibly back 845440ce-f63f-5835-903f-739145ca27bd (Zusammenhang von f und f′ am Graphen beschreiben) directly, or whether the canonical monotonicity/f-prime route still needs one more modeling adjustment first

2026-03-20: NRW upper-secondary E.2 reaches the shared `f`/`f′` graph leaf after one more canonical prerequisite cut

What changed:

the second NRW upper-secondary split child c876c75b-dcc4-426e-be0f-15698add835d now maps as a reviewed partial bridge to 845440ce-f63f-5835-903f-739145ca27bd (Zusammenhang von f und f′ am Graphen beschreiben)
the canonical prerequisite cut was tightened once more so that 845440ce-f63f-5835-903f-739145ca27bd now depends only on b1dcc191-d046-50de-984a-ee5c17157628 and no longer on 858113c5-e53b-57bb-b01f-ba95c3ddcb6f
this keeps the first shared f/f′ graph-reading leaf reachable in DE-NW without prematurely exposing the downstream tangent-calculation corridor
the accepted-warning registry now records the NRW-specific APV-202 for 845440ce-f63f-5835-903f-739145ca27bd

Interpretation:

NRW upper-secondary math now reaches the first shared graph-level relation between f and f′, not just local derivative-entry leaves
the earlier NRW source split was sufficient; the remaining blocker was canonical prerequisite shape, not another missing NRW source atom
the next NRW task should stay in the same upper-secondary derivative corridor and decide which first downstream monotonicity/extrema leaf can be opened next without dragging in broader tangent-rule fluency too early

2026-03-20: NRW upper-secondary broadens the E-phase source snapshot and reaches the first computational E.3 leaves

What changed:

the NRW upper-secondary source snapshot was widened in place inside the same E-phase analysis lane instead of forcing another canonical shortcut
the E-phase source cluster 54d2c225-f931-4ba7-ab9e-0d9055820c09 now also contains three newly imported NRW source atoms:
0c3056ad-ee56-49e8-aff4-fabcae51eb98 for Potenz-, Summen- und Faktorregel
fd54f82d-0846-4277-ae97-b3964fb41de0 for graphical derivatives, monotonicity, and extrema criteria
53563e97-253b-4f3c-8911-d1ec1ac1edb3 for curvature and Wendepunkt criteria via the second derivative

Interpretation:

NRW upper-secondary math now reaches the first genuinely computational shared E.3 analysis corridor, not only interpretive E.2 leaves
the cleaner move here was source-snapshot widening from the archived NRW KLP, not another canonical prerequisite workaround
the next NRW task should leave the pure E-phase import lane and add the first Q-phase extremal-problem source atom from 2.4.1, because 858..., 350..., and b360... are now already present on the shared canonical spine

2026-03-20: NRW upper-secondary imports the first Q-phase extremal-problem source atom and reaches the shared extremal leaf

What changed:

the NRW upper-secondary source snapshot now also carries the first explicit Q-phase Grundkurs extremal-problem atom:
ef475a7e-a647-4140-bad9-304ca3a53ef5 (Extremwertprobleme mit Nebenbedingungen auf eine Variable zurueckfuehren und loesen)
the Q-phase Grundkurs source cluster 3ad7040a-095d-4356-9972-2403cf0967bb was widened in place and renamed from a pure exponential/integral cluster to an extremal-, exponential-, and integral-understanding cluster

Interpretation:

NRW upper-secondary math now reaches the first shared optimization leaf in the canonical differential-calculus corridor, not only derivative and graph-reading atoms
the cleanest move here was a small source-snapshot widening from the archived NRW Q-phase text, not a canonical graph reshaping
the next NRW task should not immediately widen the broader Q-phase parameter/integral surface; it should first decide whether the still-unimported E-phase tangent/normal-steigung clause from 2.3 deserves a small source-split or source-addition for bb979dbd-b080-432c-8cf1-067ba6eff381 (Tangentengleichungen und Steigungswinkel bestimmen)

the next NRW task should stay on the same Q-phase integral corridor and decide whether the still-unimported Hauptsatz clause from 2.4.1 deserves a small source-add for b9bbd2a8-1379-5ffb-817f-41467d48abef (Hauptsatz der Differential- und Integralrechnung nutzen) before widening the broader parameter or exponential lane

the next NRW task should stay on the same integral corridor and decide whether the still-unimported Q-phase clause for Intervalladditivität und Linearität von Integralen or the separate Flächeninhalte mithilfe von bestimmten Integralen clause should be imported next before widening broader parameter or exponential lanes

2026-03-20: NRW upper-secondary adds the definite-integral area clause and reaches the shared area-with-integrals leaf

What changed:

the NRW upper-secondary Q-phase integral corridor was widened by one small source add instead of opening broader parameter or exponential lanes
the imported NRW snapshot now also carries the new source atom:
df210bbb-749a-40ff-841e-c2fded9cca31 (Flaecheninhalte mithilfe bestimmter Integrale ermitteln)
this atom sits as a new sibling under the retained Q-phase Grundkurs cluster 3ad7040a-095d-4356-9972-2403cf0967bb
the NRW upper-secondary mapping lane now carries 14 rows instead of 13
the new NRW source atom maps as a reviewed partial bridge to:
e9114fc2-1a87-5ef5-8fa3-7ee4c9bbe0dd (Flächen mit Integralen berechnen)
the accepted-warning registry now records the NRW-specific APV-202 entry for e9114fc2-1a87-5ef5-8fa3-7ee4c9bbe0dd
the shared NRW source-goal membership and closure registries were widened in place for the same retained upper-secondary sourceLandscapeId

Interpretation:

NRW upper-secondary math now reaches the shared area-with-integrals leaf on the canonical Q1.2 application spine, not only stock/area introduction, area approximation, and Hauptsatz leaves
the clean move here was another small Q-phase source add that isolates the explicit definite-integral area clause instead of overloading the broader imported NRW corridor
the next NRW task should stay on the same integral corridor and decide whether the still-unimported clause for Intervalladditivität und Linearität von Integralen deserves the next small source add before widening broader parameter or exponential lanes

2026-03-20: NRW upper-secondary adds the interval-additivity clause and reaches the shared integral-term argumentation leaf

What changed:

the NRW upper-secondary Q-phase integral corridor was widened by one more small source add instead of opening broader parameter or exponential lanes
the imported NRW snapshot now also carries the new source atom:
a39a1fb7-bf12-4d5b-8d73-1aafd5b18e19 (Intervalladditivitaet und Linearitaet von Integralen nutzen)
this atom sits as a new sibling under the retained Q-phase Grundkurs cluster 3ad7040a-095d-4356-9972-2403cf0967bb

Interpretation:

NRW upper-secondary math now reaches the shared integral-term argumentation leaf on the canonical Q1.2 application spine, not only the surrounding area, stock, and Hauptsatz leaves
the clean move here was another small Q-phase source add that isolates the explicit interval-additivity/linearity clause instead of forcing a broader canonical reinterpretation
the next NRW task should decide whether the remaining unimported introductory integral pair (13) / (14) deserves one last small source add for the Q1.1 introduction surface before widening broader parameter or exponential lanes

2026-03-20: NRW upper-secondary archives the remaining introductory integral pair and repoints the approximation bridge to the narrower limit-transition clause

What changed:

the NRW upper-secondary Q-phase integral corridor was widened by the two still-missing introductory source atoms instead of opening broader parameter or exponential lanes
the imported NRW snapshot now also carries the new source atoms:
371359c2-6e29-4863-879f-d53b044204ce (Graphen von Flaecheninhaltsfunktionen skizzieren)
18a7ac50-2fb1-4b2a-9eed-3f7f290bdb69 (Uebergang von der Produktsumme zum Integral erlaeutern und vollziehen)
both atoms sit as new siblings under the retained Q-phase Grundkurs cluster 3ad7040a-095d-4356-9972-2403cf0967bb
the NRW upper-secondary mapping lane still carries 15 rows, but the reviewed partial bridge for:
94d63ad9-ae1c-5ff2-b05e-188a0f5ebec6 (Flächen unter Graphen näherungsweise bestimmen) now points to the narrower source atom 18a7ac50-2fb1-4b2a-9eed-3f7f290bdb69 instead of the broader retained productsum/area atom 71539804-c722-4fe6-bc71-e4e2abe1773f
the accepted-warning registry keeps the NRW-specific APV-202 entry for 94d63ad9-ae1c-5ff2-b05e-188a0f5ebec6, but with the rationale updated to match the cleaner source clause
the shared NRW source-goal membership and closure registries were widened in place for the same retained upper-secondary sourceLandscapeId

Validation result:

the repository-backed NRW upper-secondary mapping fixture still parses cleanly with 15 rows
the NRW archived upper-secondary closure registry now resolves the imported analysis corridor with 19 atomic source goals instead of 17

npm run validate:view-filters remains at 0 errors, 3 warnings, 183 accepted warnings
full ./run_ci.sh passed after the NRW upper-secondary introductory-integral cleanup step

Interpretation:

NRW upper-secondary math does not gain a new visible canonical leaf in this step; the gain is a cleaner source-aligned backing for the existing Q1.1 approximation route and a retained source atom for the still-unmapped area-function clause
the productive open question is now narrower: whether 371359c2-6e29-4863-879f-d53b044204ce (Graphen von Flaecheninhaltsfunktionen skizzieren) justifies a future canonical integral-function / area-function leaf
if not, the NRW integral corridor is clean enough to leave here and widen the broader parameter or exponential lane instead

2026-03-20: NRW upper-secondary closes the repository mapping gap on the first shared exponential leaf

What changed:

the NRW upper-secondary source snapshot was not widened in this step; instead, the repository-backed NRW mapping lane was brought into line with the already compiled exponential entry surface
the existing NRW source atom:
c714c662-b476-4945-9352-e62869770bed (Natuerliche Exponentialfunktion beschreiben und fuer Wachstum nutzen) now maps as a reviewed partial bridge to:
781f133a-08bb-54b9-8fda-efa2f8f9b12c (Exponentialen Wachstum und Zerfall deuten)
the NRW upper-secondary mapping lane now carries 16 rows instead of 15
the accepted-warning registry now records the NRW-specific APV-202 entry for 781f133a-08bb-54b9-8fda-efa2f8f9b12c

npm run validate:view-filters remains at 0 errors, 3 warnings, 184 accepted warnings
full ./run_ci.sh passed after the NRW upper-secondary exponential mapping-gap step

Interpretation:

the substantive gain here is repository consistency: the NRW Q-phase exponential source clause is now explicitly represented in the shared mapping layer instead of depending on already-compiled state in the canonical file
the next NRW task should stay on the exponential corridor and decide whether the same broad source atom also justifies a narrower follow-on bridge such as Parameter exponentieller Funktionen interpretieren, or whether the cleaner next lane is the separate NRW parameter-from-context clause

2026-03-20: NRW upper-secondary splits the broad exponential source atom and closes the repository-backed parameter follow-on gap

What changed:

the NRW upper-secondary source snapshot was widened by a small retained split inside the existing broad exponential corridor instead of forcing an unsupported one-to-many mapping
the retained NRW source cluster:
c714c662-b476-4945-9352-e62869770bed (Natuerliche Exponentialfunktion beschreiben und fuer Wachstum nutzen) now contains three narrower source-aligned children:
70705293-c65e-4a96-b771-5b9883e1d17d (Eigenschaften exponentieller Funktionen der Form a^x beschreiben)
aa3e0764-3046-47c1-aa9b-35a144cf02d6 (Besonderheit der natuerlichen Exponentialfunktion erlaeutern)
1b742861-ac55-4a6d-bd84-71ed6c291eda (Exponentialfunktionen fuer Wachstums- und Zerfallsvorgaenge nutzen)
the NRW upper-secondary mapping lane now keeps the exponential-entry bridge on the narrower growth/decay child:
1b742861-ac55-4a6d-bd84-71ed6c291eda -> 781f133a-08bb-54b9-8fda-efa2f8f9b12c (Exponentialen Wachstum und Zerfall deuten)
and now also carries the reviewed partial follow-on bridge:
70705293-c65e-4a96-b771-5b9883e1d17d -> 346efb31-c400-5bd3-a698-dd9a7e1bc3f7 (Parameter exponentieller Funktionen interpretieren)
the NRW upper-secondary mapping lane now carries 17 rows instead of 16
the accepted-warning registry now records the NRW-specific APV-202 entry for 346efb31-c400-5bd3-a698-dd9a7e1bc3f7, and the existing NRW rationale for 781f133a-08bb-54b9-8fda-efa2f8f9b12c was narrowed to the new growth/decay child

npm run validate:view-filters remains at 0 errors, 3 warnings, 185 accepted warnings
full ./run_ci.sh passed after the NRW upper-secondary exponential source-split step

Interpretation:

NRW upper-secondary math now reaches not only the shared exponential-entry leaf, but also the next shared exponential-parameter leaf without violating the repository's one-legacy-goal/one-canonical-goal constraint
the clean move here was a small retained source split: one child for a^x-properties, one child for the special role of e^x, and one child for growth/decay usage
the next NRW task should decide whether the retained natural-exponential child aa3e0764-3046-47c1-aa9b-35a144cf02d6 now defensibly carries 628928a6-4f48-54dc-952d-dec0e69dc856 (Eigenschaften der natürlichen Exponentialfunktion nutzen), or whether the cleaner next lane is the NRW LK clause 8ddb7c8f-b27e-4353-85b4-6801a7fdfa5b on the shared function-family parameter corridor

2026-03-20: NRW upper-secondary reaches the shared natural-exponential leaf

What changed:

the NRW upper-secondary source snapshot was not widened in this step; the next clean bridge reused the retained natural-exponential child of the new exponential split
the existing NRW source atom:
aa3e0764-3046-47c1-aa9b-35a144cf02d6 (Besonderheit der natuerlichen Exponentialfunktion erlaeutern) now maps as a reviewed partial bridge to:
628928a6-4f48-54dc-952d-dec0e69dc856 (Eigenschaften der natürlichen Exponentialfunktion nutzen)

npm run validate:view-filters remains at 0 errors, 3 warnings, 186 accepted warnings
full ./run_ci.sh passed after the NRW upper-secondary natural-exponential step

Interpretation:

NRW upper-secondary math now reaches the first three shared leaves of the canonical exponential corridor: entry, parameter interpretation, and natural exponential function
the clean move here was to reuse the retained NRW e^x child directly; no further source split was needed after the previous corridor cleanup
the next NRW task should decide whether the remaining exponential corridor should continue on the logarithmic/equation-solving side, or whether the cleaner next lane is now the imported LK clause 8ddb7c8f-b27e-4353-85b4-6801a7fdfa5b on the shared function-family parameter corridor

2026-03-20: NRW upper-secondary reaches the shared natural-logarithm leaf

What changed:

the NRW upper-secondary source snapshot was widened by one small LK source add taken directly from 2.4.2 Funktionen und Analysis instead of forcing the existing function-family clause onto an unrelated logarithm target
the LK corridor cluster:
3c33eb29-3c7f-4980-acd7-e8e917eccc29 was widened from a two-atom to a three-atom retained cluster and now explicitly includes:
85be691c-c569-4cdf-b332-b9d77d47666d (Umkehrbarkeit ausgewaehlter Funktionen untersuchen und einfache Umkehrfunktionen bestimmen)
the new NRW source atom now maps as a reviewed partial bridge to:
392440db-6a43-59c0-a48d-958128fa16a8 (Natürlichen Logarithmus als Umkehrfunktion verstehen (LK))
the NRW upper-secondary mapping lane now carries 19 rows instead of 18
to keep the compiled NRW applicability path valid after this new logarithm leaf, the broad cluster-level requires were removed from:
98dcf9bd-d119-5eb1-835c-7d719f67b485 (Q2 Analytische Geometrie, Lineare Algebra und Vertiefung der Analysis)
5ebfc509-0b4c-5c60-befb-2477eb24d4b5 (Q2.1 Vertiefung der Analysis) so that both Q2 overview nodes are now child-driven instead of carrying stale cluster prerequisites that predated the NRW widening
the accepted-warning registry now records the NRW-specific APV-202 entry for 392440db-6a43-59c0-a48d-958128fa16a8

npm run validate:view-filters remains at 0 errors, 3 warnings, 187 accepted warnings
full ./run_ci.sh passed after the NRW upper-secondary natural-logarithm step

Interpretation:

NRW upper-secondary math now reaches the first shared logarithm leaf through an explicit source-backed LK clause instead of through the still-too-broad function-family corridor
the clean move here was a small source add from the NRW KLP itself plus a small canonical cleanup: the inverse-function / logarithm clause has matching prerequisite support in the already active NRW derivative and Hauptsatz corridor, but the old broad Q2 cluster prerequisites needed to be retired so the overview nodes could stay child-driven
the next NRW task should decide whether the same inverse-function lane justifies a further step on the graph-of-inverse-function relation, or whether the cleaner next move is now the retained LK function-family parameter clause 8ddb7c8f-b27e-4353-85b4-6801a7fdfa5b

2026-03-20: NRW upper-secondary reaches the shared inverse-graph leaf

What changed:

the NRW upper-secondary source snapshot was widened by one more small LK source add from 2.4.2 Funktionen und Analysis, this time for the explicit graph-of-inverse-function clause
the retained LK corridor cluster:
3c33eb29-3c7f-4980-acd7-e8e917eccc29 now carries a fourth source atom:
e0c4432f-fc34-48c2-84d8-0e998b978500 (Zusammenhang von Funktionsgraph und Umkehrgraph erlaeutern)
instead of forcing that source atom onto the existing broad reflection leaf, the canonical Q2.1 corridor now also carries the new leaf:
dbc13bb0-963b-49a8-a441-2183f4b64c8e (Zusammenhang von Funktionsgraph und Umkehrgraph erläutern (LK))
the new NRW source atom maps as a reviewed partial bridge to that new canonical leaf
the NRW upper-secondary mapping lane now carries 20 rows instead of 19
the accepted-warning registry now records the NRW-specific APV-202 entry for dbc13bb0-963b-49a8-a441-2183f4b64c8e

npm run validate:view-filters remains at 0 errors, 3 warnings, 187 accepted warnings
full ./run_ci.sh passed after the NRW upper-secondary inverse-graph step

Interpretation:

NRW upper-secondary math now reaches not only the shared natural-logarithm leaf but also the next explicit inverse-function follow-on leaf on the canonical Q2.1 corridor
the clean move here was not another weak partial onto Spiegelungen von Funktionsgraphen beschreiben, but a small new canonical leaf that isolates the inverse-graph relation instead of conflating it with x-/y-axis or origin reflections
the cleaner next NRW move is now the already imported LK function-family parameter clause 8ddb7c8f-b27e-4353-85b4-6801a7fdfa5b; only a deliberate return to the integral side would justify reopening the separate ln(x)-as-antiderivative clause

2026-03-20: NRW upper-secondary reaches the shared Q2.1 parameter corridor

What changed:

the retained canonical Q2.1 parameter node:
e7c9a459-52d1-5e29-8714-2b038c4d3a7f is no longer a single broad atom; it now acts as a small mixed-state cluster with three child leaves:
972cc7e8-be9c-444c-ba45-98e817b3cf14 (Parameter in Analysisaufgaben nutzen, bestimmen und begründen) as the retained Hessen-exact leaf
71683f37-24de-4e0f-badd-858b56fa4d64 (Parameter einer Funktion aus Kontextbedingungen bestimmen) as the NRW-exact shared entry leaf
91e2f564-3bc8-4924-af85-2a3fa84c1471 (Parameter von Funktionen und Funktionsscharen im Kontext untersuchen) as the NRW-exact LK follow-on leaf
the Hessen exact mapping for:
ed7e8906-d5a5-4ca7-8566-89b5b3034414 was repointed from the old broad node to the new retained Hessen leaf 972cc7e8-be9c-444c-ba45-98e817b3cf14
the NRW upper-secondary mapping lane now carries 22 rows instead of 20
the NRW source atoms:
99e37d46-3b0c-4989-b8a8-c8a72501fc15
8ddb7c8f-b27e-4353-85b4-6801a7fdfa5b now map exact to the two new NRW parameter leaves
no new accepted-warning entries were needed for this slice; the corridor closes through exact mappings instead of another reviewed partial

2026-04-11: BW upper-secondary Physics opens the first Leistungsfach Schwingungen follow-on

What changed:

the active BW upper-secondary Physics source snapshot:
curricula/DE/Gymnasium/input/BW/upper-secondary/source-json/DE_BAW_S_GYM_2_PHYSIK.de.json.snapshot now also carries one selected LF 3.6.3 Schwingungen cluster:
6850b598-26a2-4960-9544-52e5fc31f750 with the three retained LF leaves:
e6e0636f-ff78-4e42-99f7-0be0fcd1e151 (Ungedaempfte mechanische Schwingungsdifferentialgleichungen mit Ansatz loesen)
4cbe6dac-2bcb-44cb-83d4-6a8b7719411a (Differentialgleichung eines elektromagnetischen Schwingkreises mit Ansatz loesen)
47770f3f-cc2f-4a65-ada9-f3cceb9e9908 (Ueberlagerungen unabhaengiger Schwingungen und Schwebungen qualitativ beschreiben)
the same BW source snapshot now reaches 35 retained source goals and 27 atomic descendants
the BW upper-secondary Physics mapping lane:
curricula/DE/Gymnasium/mapping/DE-BW/upper-secondary/bw_physics_upper_secondary_to_canonical_physics.json now carries 32 reviewed rows instead of 28
the new BW LF parent maps partial onto the shared canonical Q2 surface:
fcefb129-ad4c-50a2-9762-a910caa1af16 (Q2 Schwingungen, Induktion und mechanische Wellen)
the retained BW LF mechanical DGL leaf now maps exact onto the existing canonical LK atom:
b2fb9a25-4d26-5cf2-a917-823909dcb6bd (Schwingungsgleichung loesen)
two new narrow canonical Q2 atoms were added directly in the shared Physics graph:
a7255b83-336c-4d42-ba5c-bc2f6248ea36 (Differentialgleichung des elektromagnetischen Schwingkreises mit Ansatz loesen)
4888444f-4520-437a-9ba7-e74e8f8ed129 (Ueberlagerungen unabhaengiger Schwingungen qualitativ beschreiben)
the two new canonical atoms now contribute source-backed provenance in:
curricula/DE/Gymnasium/provenance/canonical-goal-provenance-registry.json
the shared source registries:
curricula/DE/Gymnasium/provenance/source-goal-membership-registry.json
curricula/DE/Gymnasium/provenance/source-goal-closure-registry.json now also carry the new BW LF Schwingungen cluster and its three retained leaves

Why this cut:

the clean LF value-add in BW 3.6.3 Schwingungen is not another broad BF recap, but the narrow advanced strip on solving oscillation differential equations and on independent superposition / beats
the existing canonical LK atom Schwingungsgleichung loesen was already the right shared target for the mechanical DGL clause
the electromagnetic DGL clause and the qualitative superposition / beat clause had no clean one-to-one canonical leaves yet, so two new narrow Q2 atoms were added instead of forcing those BW leaves onto overly broad Thomson/resonance surfaces
this keeps the BW LF move narrow, source-led, and debt-neutral while still widening learner-visible canonical coverage

Interpretation:

BW upper-secondary Physics now reaches one first LF Schwingungen strip without reopening the earlier BF debt model
the clean move here was one selected LF follow-on with three exact leaves and one already-shared partial parent, not a broad claim on the full BW 3.6.3 surface
the next clean BW move is now the still-unopened Leistungsfach Wellen surface

2026-04-11: BW upper-secondary Physics opens the first Leistungsfach Wellen follow-on

What changed:

the BW upper-secondary source snapshot:
curricula/DE/Gymnasium/input/BW/upper-secondary/source-json/DE_BAW_S_GYM_2_PHYSIK.de.json.snapshot now also carries the retained cluster:
0be98247-e7db-4d44-9188-5c2d70a922aa (Leistungsfach: Wellen) with the two selected LF leaves:
f51888a6-7a59-4b66-a0a1-dd0adfbd0a47 (Fortschreitende ebene Transversalwellen und Momentanbilder beschreiben)
bf252790-f980-4ac4-86ae-bc8b543b7d74 (Hertz'schen Dipol und die Abstrahlung elektromagnetischer Wellen in Grundzuegen beschreiben)
the BW upper-secondary Physics mapping lane:
curricula/DE/Gymnasium/mapping/DE-BW/upper-secondary/bw_physics_upper_secondary_to_canonical_physics.json now carries 34 rows instead of 32
the two new BW LF leaves exact-resolve onto two new narrow canonical Physics atoms:
158e1c19-7ccb-4c8c-931c-b685951ab161 (Fortschreitende ebene Transversalwellen und Momentanbilder beschreiben)
5da7d4d0-878e-44fd-b398-1b1de8b636a4 (Hertz'schen Dipol als Grenzfall des Schwingkreises deuten)
those new canonical atoms were added under:
dc38c943-11f6-5f4f-945b-67e330814727 (Mechanische Wellen)
c1563745-2722-503d-819f-95d336937e2b (Elektromagnetische Wellen)
the canonical provenance registry:
curricula/DE/Gymnasium/provenance/canonical-goal-provenance-registry.json now also records both new atoms as source-backed BW leaves
the shared source registries:
curricula/DE/Gymnasium/provenance/source-goal-membership-registry.json
curricula/DE/Gymnasium/provenance/source-goal-closure-registry.json now also carry the new BW LF Wellen cluster and its two retained leaves

Why this cut:

the clean LF value-add in BW 3.6.4 Wellen is not another broad replay of the already imported BF wave strip
the first selected LF delta sits instead on:
explicit modeling of the progressing plane transverse wave via s(x,t) and the momentary snapshot
the transfer from electromagnetic oscillating circuit to radiating Hertz dipole
a broad parent bridge for the retained LF Wellen cluster would overclaim the canonical DE graph, because the selected BW slice spans one Q2 wave-modeling surface and one Q3 electromagnetic-wave surface
two new narrow canonical atoms therefore keep the move exact, source-led, and debt-neutral without widening a new partial-only BW applicability residue

Interpretation:

BW upper-secondary Physics now reaches not only the BF Wellen strip and the first LF Schwingungen strip, but also one first exact LF Wellen strip across two new canonical micro-surfaces
the clean move here was not a broad claim on full BW 3.6.4 Wellen, but one narrow selected LF follow-on that keeps the shared canonical tree didactically sharper
the next clean BW move is now the adjacent Leistungsfach Wellenoptik surface

2026-04-11: BW upper-secondary Physics opens the first Leistungsfach Wellenoptik entry

What changed:

the BW upper-secondary source snapshot:
curricula/DE/Gymnasium/input/BW/upper-secondary/source-json/DE_BAW_S_GYM_2_PHYSIK.de.json.snapshot now also carries the retained cluster:
3844f4b6-67a8-4fe7-842b-40b64f7b3054 (Leistungsfach: Wellenoptik) with the two selected LF leaves:
d78b903d-5e2b-4fe3-99b8-52a4ce593533 (Kohaerentes Licht als elektromagnetische Welle beschreiben)
d2443d8c-a324-4f3c-a83b-914c70ea1e50 (Strahlenmodell und Wellenmodell des Lichts vergleichen)
the BW upper-secondary Physics mapping lane:
curricula/DE/Gymnasium/mapping/DE-BW/upper-secondary/bw_physics_upper_secondary_to_canonical_physics.json now carries 36 rows instead of 34
the two new BW LF leaves exact-resolve onto two new narrow canonical Physics atoms:
5b90066f-b5b3-4e82-8d31-7b95ff0a0451 (Kohaerentes Licht als elektromagnetische Welle beschreiben)
8ad305d2-bde0-4223-9477-517b2943148b (Strahlenmodell und Wellenmodell des Lichts vergleichen)
both new canonical atoms were added under:
c1563745-2722-503d-819f-95d336937e2b (Elektromagnetische Wellen)
the canonical provenance registry:
curricula/DE/Gymnasium/provenance/canonical-goal-provenance-registry.json now also records both new atoms as source-backed BW leaves
the shared source registries:
curricula/DE/Gymnasium/provenance/source-goal-membership-registry.json
curricula/DE/Gymnasium/provenance/source-goal-closure-registry.json now also carry the new BW LF Wellenoptik cluster and its two retained leaves

Why this cut:

the clean first BW move on 3.6.5 Wellenoptik is not yet the full interference and far-field calculation strip
the didactically smallest reviewed entry sits first on:
coherent light as electromagnetic wave
the explicit comparison of ray and wave model of light
these two concepts were genuinely missing as narrow canonical Physics surfaces, so two new atoms improve the shared DE graph instead of just mirroring one state package label
the move therefore opens LF Wellenoptik debt-neutral and without prematurely forcing the broader interference clauses onto existing single-slit, double-slit, or grating atoms

Interpretation:

BW upper-secondary Physics now reaches a first exact LF Wellenoptik entry in addition to the earlier LF Schwingungen and LF Wellen strips
the clean move here was one conceptual entry corridor, not yet the broader quantitative interference strip of 3.6.5
the next clean BW move is now the adjacent Interferenz-/Fernfeld-follow-on inside Leistungsfach Wellenoptik

2026-03-21: Baden-Wuerttemberg lower-secondary starts the first reviewed function-corridor mapping cut

What changed:

DE-BW is now active in the canonical Gymnasium jurisdiction stack:
applicability compiler
learner-service state filters and jurisdiction normalization
root filter UI and goal-card labels
canonical Gymnasium overview root filter list and root applicability
the repository-backed Baden-Wuerttemberg Sek-I mapping lane now carries its first 4 reviewed rows:
572f46ab-e5a7-471d-955e-a07aa7ae6a72 -> 71cec9fb-3751-4d61-8b34-c5adbbf6e5f2 as exact
332b3bd1-afc0-4266-a977-49ef0843e5b1 -> 2bb4bb91-7929-483a-b735-44275f6b5cdc as partial
a7840b04-88b2-4f2a-8f94-8a75e0a27200 -> c1f50bcc-7848-4e49-b9de-0ec030cc6bca as partial
52b15961-33be-4ee9-97ec-1911dc982910 -> 09f47964-2cd0-410e-93ee-9632b582fc91 as partial
the first BW cut also needed one explicit retained prerequisite bridge:
the canonical J6 rational-number cluster stays child-driven
the BW prerequisite closure is therefore carried through the no-requires child f6a54a49-b6cf-4ab7-a185-aa08bfcb6c97 via extendedData.applicabilityOverrides
the accepted-warning registry now records:
three new BW APV-202 findings for the first partial function bridges
one BW APV-201 for the retained J6 prerequisite leaf
the Baden-Wuerttemberg lower-secondary mapping README and the repository-backed mapping fixture were aligned to the four-row state

Why this cut:

the archived BW Sek-I pilot snapshot already exposes a clean first function corridor, but not yet a source-aligned arithmetic prerequisite strip
forcing a wider BW source import just to close the first entry visibility would have slowed the bundeslandweise rollout without teaching us a new pattern
the clean compromise is therefore:
start the first BW mappings on the same shared anchors already used by NRW and Niedersachsen
keep the missing arithmetic base explicit as one reviewed retained prerequisite bridge

Validation used:

npm run validate:graph
./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
npm run apply:applicability

Validation result:

npm run apply:applicability changed 15 goals across 2 files
npm run validate:view-filters reports 0 errors, 3 warnings, and 202 accepted warnings
full ./run_ci.sh passed after the first Baden-Wuerttemberg lower-secondary mapping cut

Interpretation:

Baden-Wuerttemberg is no longer only source-archived; it now has the first real reviewed Sek-I bridges on the shared canonical math spine
the remaining BW lower-secondary debt is now concentrated in the adjacent JG7/8 linear-functions corridor, not in generic onboarding or runtime plumbing
the next clean BW step is therefore:
stay in Baden-Wuerttemberg Sek I
review the lineare-Funktionen follow-on around representation reading, line equations, and rate-of-change instead of switching to BW Sek II immediately

2026-03-21: Baden-Wuerttemberg lower-secondary opens the adjacent JG7/8 linear-functions corridor

What changed:

the repository-backed Baden-Wuerttemberg Sek-I mapping lane now carries 8 reviewed rows instead of 4
four new BW lower-secondary mappings are active:
95bee2cc-cdb0-4611-8bc9-36f6263ea417 -> a8c42ee9-2898-4247-819f-c235032ac78a as partial

72041e85-2d03-4a3c-862c-57ebc79e9dbb -> ae772695-d55e-4cc5-81bc-6605272759b4 as partial
9cb473f6-06f0-4fa3-9bf1-34445aa58551 -> 2d75fd3f-c68b-4a11-89ae-19a30fefc47a as partial
the BW linear follow-on route also needed two explicit retained prerequisite bridges:
the canonical leaf c65ecabf-d00b-4e2d-99ae-b64692325ffb now carries DE-BW through extendedData.applicabilityOverrides
because the archived BW pilot source still does not isolate a one-to-one function-value-calculation atom
the canonical leaf fd860da9-73ba-47cd-a1a8-452424915a80 also now carries DE-BW through extendedData.applicabilityOverrides
because the archived BW pilot source still does not isolate a one-to-one J7 variable-term atom for the linear-equation route
the accepted-warning registry now records:
four new BW APV-202 findings for graph reading, linear description, line equations, and linear rate-of-change interpretation
two BW APV-201 findings for the retained direct-function-value and variable-term prerequisite bridges
the Baden-Wuerttemberg lower-secondary mapping README and repository-backed mapping fixture were aligned to the new eight-row state

Why this cut:

the archived BW JG7/8 source corridor already exposes three clean linear follow-on atoms and one narrow graph-reading atom
those four atoms fit the shared canonical spine without another source split:
graph reading -> shared graph-reading leaf
y = mx + c / two-point line work -> shared linear-description and line-equation leaves
rate-of-change in context -> shared linear-parameter leaf
the only remaining gaps were direct function-value calculation and variable-term work:
instead of forcing a broader source import, the cut keeps both dependencies explicit as two reviewed retained prerequisite bridges

npm run validate:view-filters remains at 0 errors and 3 warnings; accepted warnings now stand at 207
full ./run_ci.sh passed after the Baden-Wuerttemberg JG7/8 linear follow-on cut

Interpretation:

Baden-Wuerttemberg lower-secondary now reaches the shared canonical line-reading and line-equation corridor, not just the first entry anchors
the remaining BW lower-secondary debt is no longer the first linear follow-on itself, but the still broad representation atom d45b4ec2-8604-490e-9c11-d3b8fc54251b
the next clean BW step is therefore:
stay in Baden-Wuerttemberg Sek I
decide whether that broad representation atom deserves a small retained split before any further BW Sek-II expansion

2026-03-21: Baden-Wuerttemberg lower-secondary broad representation atom becomes a retained split

What changed:

the archived BW Sek-I source atom:
d45b4ec2-8604-490e-9c11-d3b8fc54251b is no longer treated as one broad atomic bundle
instead, the archived BW source snapshot now carries a small retained split:
5e889254-5088-4c9f-ac62-e94d95113644 (Zusammenhaenge durch Tabellen, Gleichungen, Graphen oder Text darstellen)
56842db6-253b-4fea-b50c-2940db2fd174 (Zwischen Darstellungen situationsgerecht wechseln)
the downstream BW source prerequisites now point to those narrower children instead of the old broad atom:
95bee2cc-cdb0-4611-8bc9-36f6263ea417 now depends on the representation-building child
a7840b04-88b2-4f2a-8f94-8a75e0a27200 now depends on the representation-switching child
52b15961-33be-4ee9-97ec-1911dc982910 now depends on the representation-building child
eca22013-61e3-4fad-a771-fa4e224fe1d5 now depends on the representation-switching child plus the existing linear-dependency child
the shared source registries were refreshed accordingly:
source-goal-membership-registry.json
source-goal-closure-registry.json
the real-registry runtime assertion in LandscapeServiceTest now expects the two new BW source leaves instead of the old broad atom

Why this cut:

the remaining BW Sek-I blocker was no longer a canonical mapping question but a source-shape problem
the broad archived representation atom mixed two didactically different operations:
building representations from context
switching between existing representations
keeping it broad would have pushed the next BW mapping step into avoidable retained prerequisite debt
the retained split keeps the source lane honest without forcing another canonical split too early

Validation used:

npm run validate:graph
./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest'
./run_ci.sh

Validation result:

the archived BW Sek-I source closure now resolves through the two new retained children
npm run validate:view-filters remains at 0 errors and 3 warnings; accepted warnings remain at 207
full ./run_ci.sh passed after the BW retained source split

Interpretation:

Baden-Wuerttemberg lower-secondary no longer carries the broad representation-atom blocker inside the archived pilot lane
this was a source-precision cut, not a new canonical visibility cut
the next clean BW step is now no longer another Sek-I source cleanup
the next executable work item is the first reviewed Baden-Wuerttemberg upper-secondary analysis mapping pass against the already archived Kursstufe source IDs

2026-03-21: Baden-Wuerttemberg upper-secondary upgrades the first analysis cut via a retained split

What changed:

the repository-backed Baden-Wuerttemberg Sek-II mapping lane now carries 3 reviewed rows:
f84004f9-0987-40f4-88dd-830c039b7bf6 maps exact to the shared canonical motivation anchor 71cec9fb-3751-4d61-8b34-c5adbbf6e5f2 (Warum Mathematik? – Denken, Muster & Zukunft)
97ab0ab9-9444-410d-b2d9-1ac9fa935ad8 maps exact to 2afba4a2-287d-5e8f-aeee-a3bcf8652236 (Integral als Bestand und Flächeninhalt verstehen)
e0c333ea-9873-4718-819c-d39b22ccee30 maps partial to b9bbd2a8-1379-5ffb-817f-41467d48abef (Hauptsatz der Differential- und Integralrechnung nutzen)
the former broad Basisfach integral source atom 8f8c4bc8-5b0c-4a62-b6d7-f7fb263c7f1d remains a retained split cluster with two archived child atoms:
97ab0ab9-9444-410d-b2d9-1ac9fa935ad8 (Integrale als Flaecheninhalt und Bestandsaenderung deuten sowie Bestaende aus Aenderungsraten rekonstruieren)
e0c333ea-9873-4718-819c-d39b22ccee30 (Mit Hauptsatz arbeiten und Stammfunktionsgraphen deuten)
retained BW applicability now runs through the smallest derivative-and-integral prerequisite closure that keeps both active BW Kursstufe bridges didactically closed:
ae20183e-92b5-5521-b8e0-9a8662cf51f5 (Mittlere Änderungsrate berechnen und deuten)
b42bdfcc-3db7-5697-8b3e-69e50962ca86 (Differenzenquotient als Grenzwert verstehen)
858113c5-e53b-57bb-b01f-ba95c3ddcb6f (Mit Ableitungsregeln differenzieren)
94d63ad9-ae1c-5ff2-b05e-188a0f5ebec6 (Flächen unter Graphen näherungsweise bestimmen)
the canonical math landscape now carries the BW applicability closure for 94d63ad9..., so the new Hauptsatz bridge no longer fails APV-102 on an invisible prerequisite
the accepted-warning registry now records the reviewed BW end state of this cut explicitly:
one retained-prerequisite APV-201 for 94d63ad9-ae1c-5ff2-b05e-188a0f5ebec6
one partial-bridge APV-202 for b9bbd2a8-1379-5ffb-817f-41467d48abef
the BW upper-secondary mapping README, the repository-backed mapping fixture, and the real-registry landscape service test were aligned to the new third reviewed row

Why this cut:

the retained split had already isolated the smallest remaining BW Hauptsatz / Stammfunktionsgraph clause
that child is strong enough to open the shared Hauptsatz leaf as a reviewed partial bridge, but still too narrow to justify a false exact fit because it does not isolate the full canonical F(b)-F(a) routine
widening the route required one explicit retained prerequisite closure on the approximate-area atom, which is smaller and more honest than inventing another source split or forcing a broader canonical match

Validation used:

Validation result:

the repository-backed Baden-Wuerttemberg Sek-II mapping fixture now parses cleanly with 3 rows
the archived source closure coverage stays green after the retained split follow-on
npm run apply:applicability changed 2 goals across 1 file
npm run validate:view-filters remains at 0 errors and 3 warnings; accepted warnings now stand at 211
full ./run_ci.sh passed after the BW Hauptsatz follow-on

Interpretation:

Baden-Wuerttemberg upper-secondary now has two exact reviewed analysis bridges and one narrower reviewed Hauptsatz bridge on the shared derivative / integral spine
the remaining BW debt on this opened corridor is no longer source invisibility; it is the explicit retained approximation prerequisite and the still narrower-than-canonical Hauptsatz source wording
the next clean BW step should therefore stay on this same analysis surface:
the retained source-precision split on the broad Leistungsfach integral atom is now complete
the clearer follow-on is the next adjacent reviewed integral-analysis slice unless we explicitly decide to attack the remaining APV-201 / APV-202 pair first

2026-03-21: Baden-Wuerttemberg upper-secondary retained-splits the broad Leistungsfach integral atom

What changed:

the repository-backed Baden-Wuerttemberg Sek-II mapping lane now carries 5 reviewed rows
the broad Leistungsfach integral source atom:
37d1e9d7-6909-4421-a9f1-11f7b41061ff (Integrale als Bestand und Flaecheninhalt deuten, Hauptsatz nutzen und Linearitaet begruenden) now survives only as a retained split parent over:
72d7ad67-e2ef-41a0-bb52-b62eb5d071e0 (Integrale als Bestand und Flaecheninhalt deuten sowie Funktionen aus Aenderungsraten rekonstruieren)
fb742d93-6c9b-487a-bc7c-f54b363c0c01 (Integralfunktion und Stammfunktion unterscheiden, Stammfunktionsgraphen deuten und den Hauptsatz bis zur Linearitaet nutzen)
the first new Leistungsfach child now maps partial to:
2afba4a2-287d-5e8f-aeee-a3bcf8652236 (Integral als Bestand und Flächeninhalt verstehen)
the second new Leistungsfach child now maps partial to:
b9bbd2a8-1379-5ffb-817f-41467d48abef (Hauptsatz der Differential- und Integralrechnung nutzen)
the BW upper-secondary source snapshot, provenance registries, mapping README, structure note, and repository fixture were aligned to the retained split

Why this cut:

one legacy source goal can currently resolve to only one canonical goal in the backend mapping service, so the broad Leistungsfach atom had to be split before it could land on two different shared leaves honestly
the BW source wording already separates an introductory integral / reconstruction clause from a narrower Hauptsatz / Integralfunktion / Linearitaet clause well enough for a retained source split
both resulting bridges remain partial, because neither child isolates the full canonical wording exactly:
the introductory child keeps the broader Leistungsfach phrasing around reconstructing functions from rates of change
the Hauptsatz child still bundles Integralfunktion / Linearitaet breadth without isolating the full canonical F(b) - F(a) routine

Validation used:

npm run validate:graph
./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'

Validation result:

the repository-backed Baden-Wuerttemberg Sek-II mapping fixture now parses cleanly with 5 rows
the archived BW source snapshot and provenance registries remain graph-valid after the retained split

Interpretation:

the shared BW introductory-integral and Hauptsatz leaves are now both backed by retained Basisfach and Leistungsfach source children instead of one broad LF approximation
BW applicability and the reviewed APV-201 / APV-202 pair remain unchanged after this cut
the next clean BW step is now the next adjacent reviewed integral-analysis slice, unless we want to explicitly tighten the remaining applicability debt first

2026-03-21: Baden-Wuerttemberg upper-secondary retained-splits the broad Basisfach e-function atom

What changed:

the repository-backed Baden-Wuerttemberg Sek-II mapping lane now carries 7 reviewed rows
the broad Basisfach e-function source atom:
d061f00d-6118-46de-a476-ec4c9112e222 (Die natuerliche Exponentialfunktion beschreiben sowie ihre Ableitung und Stammfunktion angeben) now survives only as a retained split parent over:
e0769810-ba73-4a52-8e9c-660d1fb9d6e6 (Die natuerliche Exponentialfunktion mit Basis e beschreiben und ihre Ableitung angeben)
7bf62048-84ba-467f-ba23-f053c4e2989f (Die Stammfunktion der natuerlichen Exponentialfunktion angeben)
the first new Basisfach child now maps partial to:
4047af71-de53-5dc3-80c6-a7c78fb4bfe4 (Exponentialfunktionen)
the second new Basisfach child now maps partial to:
a9ed219d-d497-55e5-a4e0-4d45d2554f6b (Einfache Integrale berechnen)
the BW upper-secondary source snapshot, provenance registries, mapping README, structure note, repository fixture, and real-registry BW closure regression were aligned to the retained split
the accepted-warning registry now records the reviewed BW simple-integral follow-on explicitly:
one partial-bridge APV-202 for a9ed219d-d497-55e5-a4e0-4d45d2554f6b

Why this cut:

one legacy source goal can currently resolve to only one canonical goal in the backend mapping service, so the broad Basisfach atom had to be split before it could land on the shared exponential-functions cluster and the shared simple-integral leaf honestly
the BW source wording already separates an e-function / Ableitungs clause from the narrower Stammfunktionsaussage well enough for a small retained source split
both resulting bridges remain partial, because neither child isolates the full canonical wording exactly:
the e-function child does not carry the canonical continuous-process modelling surface
the Stammfunktions child is much narrower than the shared simple-integral routine

Validation used:

npm run validate:graph

npm run validate:view-filters
./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest' --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest.resolvesBadenWuerttembergArchivedAtomicClosureFromRealRegistry'

Validation result:

the repository-backed Baden-Wuerttemberg Sek-II mapping fixture now parses cleanly with 7 rows
the archived BW source snapshot and provenance registries remain graph-valid after the retained split
the shared canonical applicability layer can now surface the newly backed BW E.4 cluster and the new simple-integral leaf directly
npm run validate:view-filters returns 0 errors, 3 warnings, 212 accepted warnings after recording the new BW simple-integral partial bridge

Interpretation:

the first BW upper-secondary analysis cut now spans four shared leaves plus the shared E.4 cluster instead of only the integral pair plus the orientation anchor
the retained source-precision work is now done not only for the broad BW integral atoms but also for the first broad Basisfach e-function entry atom
the next clean BW step is the adjacent composition / optimization follow-on on the same analysis corridor

2026-03-21: Baden-Wuerttemberg upper-secondary opens the adjacent Basisfach composition / application slice

What changed:

the repository-backed Baden-Wuerttemberg Sek-II mapping lane now carries 9 reviewed rows instead of 7
two new BW Basisfach mappings are active:
46690ab9-0b1f-4bd9-9409-4976a40c6ec2 -> e9ad45b9-c0d2-5804-b6bf-79e5ce041d2c as partial

these retained bridges keep the new BW upper-secondary route didactically closed without widening the archived BW pilot source lanes or forcing another source split
the accepted-warning registry now records the reviewed BW debt for this cut explicitly:
five new APV-201 entries for the retained prerequisite bridges above
one BW APV-202 for e9ad45b9-c0d2-5804-b6bf-79e5ce041d2c
one BW APV-202 for 1511b39a-4094-5450-a755-4a3ad3339733
the BW upper-secondary mapping README, structure note, expansion plan note, and repository fixture were aligned to the new nine-row state

Why this cut:

the archived BW Basisfach corridor already exposed a clean next pair immediately after the retained e-function split:
one composition atom with linear inner function
one application atom for extremal work and function-term recovery
both source atoms fit existing canonical leaves closely enough for reviewed partial bridges, but neither source clause is narrow enough for an exact match:
the composition source stays on graphical sum/product/composition work with linear inner functions
the application source bundles contextual extremal work together with graph-property based function reconstruction
the only real blocker was applicability closure:
the optimization leaf still depends on derivative-graph interpretation atoms not isolated in the BW source snapshot
the composition leaf still depends on a shared Q1 recap route that in turn reaches back into the late Sek-I exponential bridge
explicit retained prerequisite overrides were therefore the smaller and more honest move than opening new BW source corridors just to satisfy those dependencies mechanically

npm run validate:graph still reports 593 landscapes passed
npm run validate:view-filters remains at 0 errors, 3 warnings, 219 accepted warnings
full ./run_ci.sh passed after the BW Basisfach composition / application step

Interpretation:

Baden-Wuerttemberg upper-secondary now reaches the first shared composition and simple-extremal leaves on the opened analysis spine, not only the earlier e-function and integral route
the remaining BW debt on this corridor is no longer the Basisfach follow-on itself, but the still-unmapped aligned Leistungsfach composition / application pair
the next clean BW step is therefore the adjacent Leistungsfach follow-on around:
13e285f3-522c-4eae-9fed-8b13b2af7b7d
8ab263f6-a460-4ca2-bbe9-b7e9a22bbaa2

2026-03-21: Baden-Wuerttemberg upper-secondary opens the aligned Leistungsfach composition / application follow-on

What changed:

the repository-backed Baden-Wuerttemberg Sek-II mapping lane now carries 11 reviewed rows instead of 9
two new BW Leistungsfach mappings are active:
13e285f3-522c-4eae-9fed-8b13b2af7b7d -> e9ad45b9-c0d2-5804-b6bf-79e5ce041d2c as partial
8ab263f6-a460-4ca2-bbe9-b7e9a22bbaa2 -> 1511b39a-4094-5450-a755-4a3ad3339733 as partial
no new retained applicability bridges were needed in the canonical math graph for this follow-on
no new accepted-warning entries were needed either:
the two target leaves were already active for DE-BW
the existing reviewed BW APV-202 entries on those shared leaves remain sufficient
the BW upper-secondary mapping README, structure note, expansion-plan note, and repository fixture were aligned to the new eleven-row state

Why this cut:

this is the smallest honest next step on the already opened BW upper-secondary analysis corridor:
the new Leistungsfach composition source stays closest to the shared exponential/polynomial-combination leaf even though it also carries a quotient/asymptote side clause
the new Leistungsfach application source stays closest to the shared simple-extremal-problem leaf even though it also bundles function-term recovery and first function-family work
both bridges remain partial, because neither BW Leistungsfach clause isolates the full canonical wording exactly:
the composition source is broader on asymptotes and zeros, but narrower on the shared contextual investigation surface
the application source combines extremal work with graph-property and Schar questions instead of isolating only the simple contextual extremal leaf
unlike the preceding Basisfach step, this follow-on does not open any new canonical prerequisite chain:
both shared targets were already visible for DE-BW
the earlier retained BW prerequisite overrides therefore already closed the relevant applicability surface

Interpretation:

Baden-Wuerttemberg upper-secondary now reaches the shared composition and simple-extremal leaves through both Basisfach and Leistungsfach follow-on children, not only through the earlier Basisfach slice
the remaining open BW debt on this corridor is now narrower and clearer:
the still-broad Leistungsfach e/logarithm front atom fa4597c7-fabd-4a55-8be3-d06f7c432738
the next clean BW step should therefore decide whether that broad Leistungsfach front atom needs its own retained split or whether one direct reviewed bridge is already honest enough

2026-03-20: NRW upper-secondary broad E-phase polynomial atom becomes a retained split with one exact canonical bridge

What changed:

the broad NRW E-phase source atom:
22e2cc01-be7c-4478-8d22-0409ff5b14a0 is no longer a single archived atomic bundle
instead, the retained NRW source snapshot now splits it into:
ae5ec3d2-7ff8-4f08-92c0-5dec8006cf81 (Potenzfunktionen mit ganzzahligen Exponenten beschreiben)
fb1eebf2-3d5d-40a6-a0e5-879bb7d4f422 (Ganzrationale Funktionen beschreiben)
the NRW upper-secondary mapping lane now carries 25 rows instead of 24
the new polynomial child:
fb1eebf2-3d5d-40a6-a0e5-879bb7d4f422 maps exact to the existing canonical J10 leaf:
1ce8af38-082a-477b-af48-b924c92761bf (Ganzrationale Funktionen beschreiben)
the archived NRW source registries were widened in place:
source-goal-membership-registry.json now includes the two new retained child IDs
source-goal-closure-registry.json now resolves the broad parent through those two children instead of treating 22e2cc01... as atomic

Why this cut:

the NRW source wording is broader than any single existing canonical E-phase leaf
the polynomial half already matches an existing shared canonical J10 atom cleanly enough for an exact bridge
the power-function half still has no equally clean one-to-one target, so forcing a second bridge here would only create a weak breadth mismatch

Validation used:

npm run validate:graph
./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest' --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest'
npm run apply:applicability
npm run validate:view-filters
./run_ci.sh

Validation result:

the repository-backed NRW upper-secondary mapping fixture now parses cleanly with 25 rows
the archived NRW closure regression now resolves the E-phase analysis cluster through the two new retained children instead of the old broad atomic bundle
npm run apply:applicability changed 2 goals across 1 file
npm run validate:view-filters remains at 0 errors, 3 warnings, 184 accepted warnings
full ./run_ci.sh passed after the NRW retained source split and exact polynomial bridge

Interpretation:

NRW upper-secondary math no longer keeps the broad E-phase polynomial corridor only as unmapped structural source material
instead, the shared canonical J10 polynomial leaf is now repository-backed for DE-NW, while the remaining NRW power-function clause stays explicitly unresolved rather than being stretched onto the wrong canonical target
the next clean NRW source-led decision is now the retained power-function child ae5ec3d2-7ff8-4f08-92c0-5dec8006cf81, not the already-closed broad parent 22e2cc01...

2026-03-20: NRW upper-secondary power-function child becomes an exact canonical late-Sek-I bridge

What changed:

the retained NRW E-phase source child:
ae5ec3d2-7ff8-4f08-92c0-5dec8006cf81 (Potenzfunktionen mit ganzzahligen Exponenten beschreiben) now maps exact in the NRW upper-secondary lane
instead of forcing another reviewed partial onto the broader existing J9 graph/root leaf, the canonical late-Sek-I power corridor now carries a small mixed-state split:
the shared cluster 289db903-2831-45ef-afc2-c0619c91d680 (Potenzfunktionen und Potenzgesetze nutzen) now contains three children
the existing HE/BY graph/root leaf 66077296-a8f8-4645-938b-7c3424cb2f14 stays exact for the broader Potenz-/Wurzelfunktionssurface
the new NRW-exact leaf 30c013ac-5164-4c3c-8bc1-9a10b2f49533 (Potenzfunktionen mit ganzzahligen Exponenten beschreiben) now carries the narrower source wording directly
the same canonical late-Sek-I power cluster now sequences child-driven instead of via the old cluster-wide prerequisite, so DE-NW does not need an artificial prerequisite bridge just to make the narrower exact leaf visible
the NRW upper-secondary mapping lane now carries 26 rows instead of 25

Why this cut:

the retained NRW source wording is narrower than the existing shared J9 leaf 66077296..., because it does not also cover Wurzelfunktionen or the fuller graph/transformation surface
but it is still strong enough for an exact shared canonical leaf inside the same late-Sek-I power corridor
this keeps the corridor repository-backed for DE-NW without introducing another APV-202 breadth mismatch

Validation used:

npm run validate:graph
./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
npm run apply:applicability
npm run validate:view-filters
./run_ci.sh

Validation result:

the repository-backed NRW upper-secondary mapping fixture now parses cleanly with 26 rows
npm run apply:applicability changed 1 goal across 1 file while recompiling the late-Sek-I power corridor with the new NRW-exact leaf
npm run validate:view-filters remains at 0 errors, 3 warnings, 184 accepted warnings
full ./run_ci.sh passed after the canonical split and exact NRW bridge

Interpretation:

NRW upper-secondary math no longer leaves the retained power-function child as unresolved source-only structure
the shared canonical late-Sek-I power corridor is now active for DE-NW through an exact leaf rather than a reviewed partial
the corridor no longer needs a synthetic NRW prerequisite workaround, because the shared cluster is now sequenced through its children rather than an inherited cluster-wide requires
the remaining NRW upper-secondary unmapped atom is now only 71539804-c722-4fe6-bc71-e4e2abe1773f (Produktsummen und Flächeninhalte im Sachkontext deuten), which remains deliberately source-structural after the narrower integral splits

2026-03-20: NRW upper-secondary retained productsum/area atom becomes an exact canonical Q1.1 leaf

What changed:

the previously retained NRW Q1.1 source atom:
71539804-c722-4fe6-bc71-e4e2abe1773f (Produktsummen und Flächeninhalte im Sachkontext deuten) now maps exact
the canonical Q1.1 introduction cluster:
93ac7fc8-6d83-5394-bbea-80758b463da1 now also contains the new NRW-backed leaf:
269675a9-13cd-4a3a-ab75-63794f5c9710 (Produktsummen und orientierte Flächen im Sachkontext deuten)
the Q1.1 cluster description now names product sums explicitly and its weight advances from 6 to 7
the repository-backed NRW upper-secondary mapping lane now carries 27 rows instead of 26

Why this cut:

the retained NRW source wording is narrower than the existing canonical leaves for
2afba4a2-287d-5e8f-aeee-a3bcf8652236 (Integral als Bestand und Flächeninhalt verstehen)
34604a97-0c64-5b06-81e2-6ac818732d60 (Integralterme interpretieren und begründen)
but it is still precise enough to justify its own exact canonical entry leaf in Q1.1
this closes the last unmapped atomic goal in the current NRW upper-secondary source snapshot without creating another reviewed breadth mismatch

Validation used:

npm run validate:graph
./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
npm run apply:applicability
npm run validate:view-filters

Validation result:

the repository-backed NRW upper-secondary mapping fixture now parses cleanly with 27 rows
npm run apply:applicability changed 0 goals across 0 files because the committed applicability state was already consistent with the new exact leaf
npm run validate:view-filters remains at 0 errors, 3 warnings, 184 accepted warnings
full ./run_ci.sh passed after the new exact Q1.1 leaf

Interpretation:

the current NRW upper-secondary pilot snapshot now has 0 unmapped atomic source goals
NRW is no longer carrying a deliberately retained leftover inside the current Q1.1 integral surface
the next NRW decision is no longer “close the last leftover atom”, but whether to widen NRW source breadth further or move to the next Bundesland onboarding lane

2026-03-20: Niedersachsen mathematics mapping-lane setup opens the post-NRW Stage-B lane

What changed:

the next post-NRW onboarding lane is now prepared for DE-NI
the first real DE-NI canonical math mapping fixtures now exist at:
curricula/DE/Gymnasium/mapping/DE-NI/lower-secondary/ni_math_lower_secondary_to_canonical_math.json
curricula/DE/Gymnasium/mapping/DE-NI/upper-secondary/ni_math_upper_secondary_to_canonical_math.json
both fixtures are repository-backed and test-covered, but intentionally still empty (0 mappings)
stable Niedersachsen source-landscape IDs are now reserved for the future source snapshots:
lower-secondary math: 2b995085-dc5e-47c6-a563-9dcfc01fb74d
upper-secondary math: fcb04661-6ea2-4030-a9b2-97e6cc03daf8
the reservation and no-premature-activation rule now live in:
curricula/DE/Gymnasium/provenance/ni-math-onboarding.md
the new DE-NI mapping-lane READMEs record the planned lane purpose and current non-activated state

Why this cut:

the current NRW pilot subset already has 0 unmapped atomic source goals, so the next reusable learning step is no longer another local NRW cleanup
Niedersachsen is the cleanest remaining placeholder lane for repeating the early multi-state onboarding pattern once more:
one provider family (NIBIS)
explicit mathematics references for both Sek I and Sek II
no immediate need to mix multiple unrelated subject imports into the same state step
committing empty repository-backed fixtures first keeps the reserved IDs stable and test-visible before any real NI source snapshots exist

Validation used:

./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
./run_ci.sh

Validation result:

both Niedersachsen mapping fixtures parse cleanly with 0 mappings
full ./run_ci.sh passed after the new DE-NI scaffold and fixture coverage

Interpretation:

Stage B from canonical-gymnasium-math-de-expansion-plan.md is now prepared for Niedersachsen mathematics
the next Niedersachsen blocker is no longer repository setup, but source import:
archive the NI mathematics source bundle under curricula/DE/Gymnasium/input/NI/
then activate shared provenance only after real source snapshots with stable source goal IDs exist

2026-03-20: Niedersachsen mathematics source import completes Stage A after the new Stage-B lane

What changed:

the official Niedersachsen mathematics source PDFs are now archived locally under curricula/DE/Gymnasium/input/NI/
lower-secondary mathematics now lives at:
curricula/DE/Gymnasium/input/NI/lower-secondary/ma_gym_si_kc_druck.pdf
upper-secondary mathematics now lives at:
curricula/DE/Gymnasium/input/NI/upper-secondary/ma_go_kc_druck_2019.pdf
source provenance is documented beside each file in:
curricula/DE/Gymnasium/input/NI/lower-secondary/references.md
curricula/DE/Gymnasium/input/NI/upper-secondary/references.md
the Niedersachsen input README now reflects the archived-file state for mathematics instead of only pointing to generic NIBIS landing pages

Why this cut:

after the new DE-NI mapping-lane scaffold, the next reusable blocker was no longer repository shape but raw source availability
archiving the official PDFs first keeps the state-owned source bundle stable before any source-snapshot extraction begins
this mirrors the earlier NRW onboarding order closely enough to keep the next multi-state comparison step mechanical

Validation used:

./run_ci.sh

Validation result:

full ./run_ci.sh passed after the Niedersachsen archive import

Interpretation:

Stage A and Stage B are now complete for Niedersachsen mathematics
the next Niedersachsen blocker is Stage C:
import the first archived NI source snapshots with stable source goal IDs
then activate shared provenance only after those snapshots exist

2026-03-20: Niedersachsen lower-secondary pilot source snapshot completes the first Stage-C activation

What changed:

the first real Niedersachsen Sek-I source snapshot now exists at:
curricula/DE/Gymnasium/input/NI/lower-secondary/source-json/DE_NDS_S_GYM_1_MATHEMATIK.de.json.snapshot
the new archived source landscape uses the reserved Niedersachsen lower-secondary math sourceLandscapeId:
2b995085-dc5e-47c6-a563-9dcfc01fb74d
the first imported NI pilot subset is deliberately small and source-led:
curriculum-wide Funktionaler Zusammenhang motivation
Proportionale und antiproportionale Zusammenhaenge
Lineare Zusammenhaenge
the lower-secondary Niedersachsen source lane is now active in shared provenance:
curricula/DE/Gymnasium/provenance/source-landscape-registry.json
curricula/DE/Gymnasium/provenance/source-goal-membership-registry.json
curricula/DE/Gymnasium/provenance/source-goal-closure-registry.json
the local NI source inventory now also includes:
curricula/DE/Gymnasium/input/NI/math-structure-note.md
archived-source runtime handling and test coverage were widened for Niedersachsen:
backend/src/main/java/com/skillpilot/backend/landscape/LandscapeService.java
backend/src/test/java/com/skillpilot/backend/landscape/LandscapeServiceTest.java

Why this cut:

after NI Stage A and Stage B, the next reusable step was no longer repository setup but a first real archived source landscape with stable source goal IDs
the lower-secondary functions corridor is the cleanest first Niedersachsen subset because it matches the already proven NRW onboarding shape without immediately forcing a broader subject import
activating provenance at this point keeps the future NI mapping work grounded in repository-backed source IDs instead of PDF-only references

Validation used:

./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
./run_ci.sh

Validation result:

the new Niedersachsen lower-secondary pilot source landscape loads from the real registry
its archived atomic closure resolves correctly for the first NI functions corridor
full ./run_ci.sh passed after the new snapshot, provenance activation, and test coverage

Interpretation:

Stage C is now complete for the first Niedersachsen lower-secondary pilot subset
Niedersachsen upper-secondary remains source-PDF-only for now
the next Niedersachsen blocker is therefore narrower than before:
import the first NI upper-secondary source snapshot with stable source goal IDs
then activate the shared provenance registries for that upper-secondary lane

2026-03-20: Niedersachsen upper-secondary pilot source snapshot closes the first Stage-C source pair

What changed:

the first real Niedersachsen Sek-II source snapshot now exists at:
curricula/DE/Gymnasium/input/NI/upper-secondary/source-json/DE_NDS_S_GYM_2_MATHEMATIK.de.json.snapshot
the new archived source landscape uses the reserved Niedersachsen upper-secondary math sourceLandscapeId:
fcb04661-6ea2-4030-a9b2-97e6cc03daf8
the first imported NI upper-secondary pilot subset is deliberately small and source-led:
the Einfuehrungsphase orientation layer for the gemeinsame Basis der Qualifikationsphase
Elementare Funktionenlehre
Ableitungen
the upper-secondary Niedersachsen source lane is now also active in shared provenance:
curricula/DE/Gymnasium/provenance/source-landscape-registry.json
curricula/DE/Gymnasium/provenance/source-goal-membership-registry.json
curricula/DE/Gymnasium/provenance/source-goal-closure-registry.json
the local NI source inventory now records both active pilot snapshots in:
curricula/DE/Gymnasium/input/NI/math-structure-note.md
archived-source runtime handling and registry-backed tests now also cover the Niedersachsen upper-secondary lane:
backend/src/main/java/com/skillpilot/backend/landscape/LandscapeService.java
backend/src/test/java/com/skillpilot/backend/landscape/LandscapeServiceTest.java

Why this cut:

after the lower-secondary NI Stage-C step, the cleanest next move was to activate the matching upper-secondary analysis entry corridor before starting any Niedersachsen mapping authoring
Elementare Funktionenlehre plus Ableitungen in the Einfuehrungsphase is the smallest upper-secondary NI subset that can later support the shared change-rate and derivative-entry canonical spine
activating both NI source lanes first keeps the next reviewed mappings source-grounded on repository-backed IDs for Sek I and Sek II alike

Validation used:

./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'

Validation result:

the new Niedersachsen upper-secondary pilot source landscape loads from the real registry
its archived atomic closure resolves correctly for the first NI upper-secondary analysis corridor
full ./run_ci.sh passed after the new snapshot, provenance activation, and test coverage

Interpretation:

Stage C is now complete for the initial Niedersachsen lower-secondary and upper-secondary pilot source pair
the next Niedersachsen blocker is no longer source import, but the first reviewed canonical mapping pass
the clean next execution order is:
first NI Sek I motivation and function anchors
then NI Sek II change-rate / derivative-entry anchors

2026-03-20: Niedersachsen first mapping pass stops at a clean D0-style cut instead of forcing the functions corridor

What changed:

DE-NI is now supported end-to-end in the canonical Gymnasium jurisdiction layer:
app/scripts/applicabilityCompiler.ts
backend/src/main/java/com/skillpilot/backend/service/LearnerService.java
app/src/components/PersonalCurriculumSetup.tsx
app/src/components/GoalCard.tsx
curricula/DE/Gymnasium/canonical/DE_DEU_S_GYM_CANONICAL_OVERVIEW.de.json
the first reviewed Niedersachsen lower-secondary mapping is now live:
e1942eb6-f1a5-45a7-b160-c7be0b5e30fa
maps exact to the shared canonical motivation atom:
71cec9fb-3751-4d61-8b34-c5adbbf6e5f2 (Warum Mathematik? – Denken, Muster & Zukunft)
the first NI lower-secondary source pass was widened before keeping any broader function bridges:
curricula/DE/Gymnasium/input/NI/lower-secondary/source-json/DE_NDS_S_GYM_1_MATHEMATIK.de.json.snapshot now contains a new arithmetic prerequisite strip for the active functions corridor:
fractions
decimals
positive / negative numbers on the number line
that widened lower-secondary NI source strip is now also active in shared provenance:
curricula/DE/Gymnasium/provenance/source-goal-membership-registry.json
curricula/DE/Gymnasium/provenance/source-goal-closure-registry.json
the repository-backed NI lower-secondary mapping lane was intentionally cut back to the stable green subset:
one exact motivation bridge
no retained NI functions / proportional / linear bridges yet
repository-backed tests were widened to cover the clean NI intermediate state:
backend/src/test/java/com/skillpilot/backend/landscape/GoalMappingRepositoryFixtureTest.java
backend/src/test/java/com/skillpilot/backend/landscape/LandscapeServiceTest.java

Why this cut:

the first Niedersachsen functions attempt immediately exposed two reusable rollout problems:
the canonical DE-level jurisdiction plumbing still lacked explicit DE-NI support
the NI lower-secondary function corridor sits behind a longer arithmetic prerequisite chain than the first minimal mapping slice could safely satisfy
instead of keeping weak or half-supported NI function bridges, the cleaner move was:
activate DE-NI properly at root/compiler/runtime level
keep the first exact shared motivation bridge
archive the missing arithmetic prerequisite strip directly in the NI source snapshot
leave the broader functions pass for the next arithmetic-backed mapping slice

Validation result:

the clean NI lower-secondary repository fixture now parses with 1 mapping instead of an empty lane

npm run apply:applicability changed 5 goals across 2 files while compiling the new DE-NI jurisdiction support and root visibility
npm run validate:view-filters remains at 0 errors, 3 warnings, 184 accepted warnings
full ./run_ci.sh passed after the NI jurisdiction activation, source widening, and intermediate mapping cut

Interpretation:

Niedersachsen is no longer at pure Stage-C-only source readiness:
the first clean Stage-D0-style slice is now complete
the first reusable NI lesson is not yet a kept functions bridge, but the shape of the missing prerequisite corridor
the next Niedersachsen step should therefore be:
first bridge the new NI arithmetic prerequisite strip into the shared lower-secondary arithmetic spine
then retry the NI proportional / linear functions corridor
only after that resume the first NI upper-secondary derivative-entry bridges

2026-03-20: Niedersachsen lower-secondary arithmetic prerequisite strip closes as exact J6 spine bridges

What changed:

the widened Niedersachsen lower-secondary arithmetic strip is no longer source-only; it now maps exactly into the shared canonical J6 rational-number corridor:
430a4b3b-1442-4542-a27a-5fe8726dc447 -> f6a54a49-b6cf-4ab7-a185-aa08bfcb6c97
2c6d3275-ac7d-47d9-9de6-bbf2ad6b4d69 -> 2f565855-bcd6-4da5-bc80-4b72a2d93d50
20f4e9dc-d898-45e2-b7df-eb89c9ee6195 -> 199fe2ed-2576-4611-b8de-fd56fb9f78fc
the repository-backed Niedersachsen Sek-I mapping lane now carries 4 rows instead of 1:
shared motivation exact bridge
three exact arithmetic prerequisite bridges
the canonical J6 rational-number cluster:
de39c9fe-5940-4320-aca8-2be85d6ada8f now contains three new NI-exact leaves for:
fraction representations plus compare / reduce / expand
decimal numbers on the number line, in place value form, and as fractions
positive and negative numbers on the number line
the old cluster-wide requires claim on:
de39c9fe-5940-4320-aca8-2be85d6ada8f was removed so the rational-number corridor can compile applicability child-driven instead of failing on non-imported legacy prerequisites
cluster weights were advanced for the directly affected J6 branch:
Rationale Zahlen darstellen und berechnen
Jahrgang 6 (Sek I)
the NI lane README and repository-backed fixture were aligned to the new exact four-row state

Why this cut:

the widened NI prerequisite strip was already source-backed and source-atomic; keeping it unmapped would have left the next NI functions pass blocked behind known but still dormant arithmetic groundwork
none of the existing canonical J6 leaves matched the NI source wording cleanly enough for safe exact reuse:
the fraction leaf in NI combines representation use with compare / reduce / expand
the decimal leaf is representation-driven, not just conversion-driven
the signed-number leaf is narrower than the existing broad rational-number line leaf
the cleaner move was therefore a small exact canonical extension inside the existing J6 rational-number cluster, not another reviewed partial bridge

full ./run_ci.sh passed after the NI arithmetic bridge pass

Interpretation:

Niedersachsen is now past the pure D0-style activation cut:
the first clean D1-style arithmetic spine bridge is complete
the next reusable NI question is no longer prerequisite import, but whether the function corridor now closes cleanly on top of that exact arithmetic base
the next Niedersachsen step should therefore be:
retry the NI lower-secondary proportional / linear functions corridor
only after that resume the first NI upper-secondary derivative-entry bridges

2026-03-20: Niedersachsen lower-secondary function corridor reopens on the shared proportional / linear spine

What changed:

the Niedersachsen Sek-I mapping lane now carries 8 reviewed rows instead of 4:
the existing exact motivation bridge
the existing three exact arithmetic prerequisite bridges
one new exact lower-secondary function bridge:

three new reviewed partial follow-on bridges:
- 52bd16c1-ce2a-46ac-a89c-8c41cc40bf9e -> c1f50bcc-7848-4e49-b9de-0ec030cc6bca

after applicability compilation, DE-NI is now visible on the shared canonical lower-secondary function spine for:
Zuordnungen analysieren
Proportionale Zuordnungen nutzen
Funktionsbegriff und Darstellungen verstehen
Lineare Funktionen beschreiben
the repository-backed Niedersachsen Sek-I fixture and lower-secondary mapping README were aligned to the new eight-row state
three reviewed Niedersachsen APV-202 entries were added for the intentionally broader partial bridges:
proportionality
function representations
linear-function foundations

Why this cut:

the arithmetic prerequisite strip is now exact and active, so the NI functions corridor no longer had to stay dormant behind known groundwork
Zuordnungen mit Worten, Tabellen und Graphen ... is already narrow enough for a clean exact bridge to the shared canonical mappings atom
the next three NI source atoms are didactically useful but still broader than the current canonical leaves:
proportionality also carries relation discrimination and multiple interpretation routes
the linear-representations clause still lacks the full canonical function-language wording
the linear-analysis clause also includes equations, roots, parameter variation, and modelling
the cleaner move was therefore:
reopen the shared lower-secondary function spine for Niedersachsen now
keep the first NI bridge exact where the wording already matches
record the broader follow-on bridges explicitly as reviewed partial, not force premature canonical splits

Validation used:

npm run validate:graph
./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
npm run apply:applicability
npm run validate:view-filters

Validation result:

the Niedersachsen Sek-I repository mapping fixture now parses cleanly with 8 rows
npm run apply:applicability changed the shared canonical math landscape while compiling the reopened NI function spine
npm run validate:view-filters remains at 0 errors, 3 warnings, 187 accepted warnings
full ./run_ci.sh passed after the NI lower-secondary function-bridge pass

Interpretation:

Niedersachsen now also has a clean D2-style lower-secondary function result:
one exact shared function-anchor bridge
three reviewed partial follow-on bridges on the shared proportional / linear spine
the next Niedersachsen step should therefore be:
resume the first NI upper-secondary change-rate / derivative-entry bridges
only return to lower-secondary again if a clearly source-atomic downstream NI clause emerges

2026-03-20: Niedersachsen upper-secondary reaches the next shared E.2 qualitative derivative-entry leaf

What changed:

the Niedersachsen Sek-II mapping lane now carries a second reviewed row in the same retained derivative-entry corridor:
234dde5d-cc9d-4508-af9e-092e614ea304 -> 2143e9e8-b176-545b-b2fa-91bbb6c8cf5c as partial
the NI source atom Lokale Aenderungsrate und Tangentensteigung mit propaedeutischem Grenzwertbegriff entwickeln is now reused once for the shared canonical leaf Momentane Änderungsrate qualitativ verstehen
the shared canonical difference-quotient prerequisite b42bdfcc-3db7-5697-8b3e-69e50962ca86 now carries an explicit retained DE-NI applicability override so the qualitative follow-on route can compile cleanly
the repository-backed Niedersachsen Sek-II fixture and upper-secondary mapping README were aligned to the new two-row state
the accepted-warning registry now records:
the Niedersachsen-specific APV-202 for 2143e9e8-b176-545b-b2fa-91bbb6c8cf5c
the matching retained-prerequisite APV-201 for b42bdfcc-3db7-5697-8b3e-69e50962ca86

Why this cut:

the NI source wording fits the qualitative derivative-entry follow-on more closely than the narrower computational limit leaf:
it develops local rate of change from average rates
and tangent slope from secant slopes
but it does not yet isolate the canonical h -> 0 determination step as a separate one-to-one source atom
this is therefore the same bounded pattern already proven in NRW:
retain the shared limit prerequisite explicitly
and let the broader NI source atom open the next qualitative derivative-entry leaf as a reviewed partial

npm run apply:applicability stays idempotent for this slice at 0 changed goals across 0 files because the canonical math file is already aligned to the retained NI qualitative derivative-entry route
npm run validate:view-filters remains at 0 errors, 3 warnings, 191 accepted warnings
full ./run_ci.sh passed after the NI upper-secondary qualitative derivative-entry pass

Interpretation:

Niedersachsen upper-secondary math now reaches the first two shared canonical derivative-entry leaves through a bounded retained route
the next Niedersachsen step should stay in the same upper-secondary corridor:
either 6c021ee2-f600-4977-a4a8-877ece6c8c3b against the pointwise derivative-interpretation leaf
or a small retained NI source split if that follow-on alignment turns out too broad

2026-03-20: Niedersachsen upper-secondary reaches the shared pointwise derivative-interpretation leaf

What changed:

the Niedersachsen Sek-II mapping lane now carries a third reviewed row in the same E.2 corridor:
6c021ee2-f600-4977-a4a8-877ece6c8c3b -> b1dcc191-d046-50de-984a-ee5c17157628 as partial
the NI source atom Ableitung als lokale Aenderungsrate und Tangentensteigung deuten is now reused once for the shared canonical leaf Ableitung als Steigung im Punkt deuten
the repository-backed Niedersachsen Sek-II fixture and upper-secondary mapping README were aligned to the new three-row state
the accepted-warning registry now records the Niedersachsen-specific APV-202 for b1dcc191-d046-50de-984a-ee5c17157628

Why this cut:

this is the cleanest next NI follow-on after the retained qualitative route:
the source atom explicitly interprets the derivative as local rate of change and tangent slope
and the canonical target narrows that same idea to the derivative value at a point
the fit is still intentionally kept as reviewed partial, because the NI wording remains slightly broader and example-based rather than fully point-value-specific
no new retained prerequisite bridge is needed here:
the already-open NI b42bdfcc-3db7-5697-8b3e-69e50962ca86 prerequisite route is sufficient for the shared pointwise interpretation leaf

npm run validate:view-filters remains at 0 errors, 3 warnings, 192 accepted warnings
full ./run_ci.sh passed after the NI upper-secondary pointwise derivative-interpretation pass

Interpretation:

Niedersachsen upper-secondary math now reaches the first three shared canonical derivative-entry leaves through one bounded retained route
the next Niedersachsen step should stay in the same upper-secondary corridor:
either d1ca482c-4184-464f-a057-2d61ba077803 against the derivative-graph leaf
or 5b284b66-f417-4366-8685-012ae000b3b1 against the elementary-derivative-rules leaf

2026-03-20: Niedersachsen upper-secondary reaches the shared derivative-graph leaf

What changed:

the Niedersachsen Sek-II mapping lane now carries a fourth reviewed row in the same E.2 corridor:
d1ca482c-4184-464f-a057-2d61ba077803 -> 845440ce-f63f-5835-903f-739145ca27bd as partial
the NI source atom Funktionsgraph und Ableitungsgraph zusammen beschreiben is now reused once for the shared canonical leaf Zusammenhang von f und f′ am Graphen beschreiben

the accepted-warning registry now records the Niedersachsen-specific APV-202 for 845440ce-f63f-5835-903f-739145ca27bd

Why this cut:

this is the cleanest next NI follow-on after the pointwise interpretation step:
the source atom explicitly relates function graph and derivative graph in both directions
and the canonical target narrows that same relation to sign, course, monotonicity, and extrema
the bridge remains reviewed partial because the NI wording is broader and also references inflection points
no new retained prerequisite bridge is needed here:
the already-open NI route through b1dcc191-d046-50de-984a-ee5c17157628 is sufficient for this derivative-graph leaf

either 5b284b66-f417-4366-8685-012ae000b3b1 against the elementary-derivative-rules leaf
or a small NI follow-on on the graph/curve-discussion side if a cleaner source-atomic clause emerges

2026-03-20: Niedersachsen upper-secondary reaches the shared elementary-derivative-rules leaf

What changed:

the Niedersachsen Sek-II mapping lane now carries a fifth reviewed row in the same E.2 corridor:
5b284b66-f417-4366-8685-012ae000b3b1 -> 858113c5-e53b-57bb-b01f-ba95c3ddcb6f as partial
the NI source atom Standardableitungen sowie Summen- und Faktorregel nutzen is now reused once for the shared canonical leaf Ableitungen elementarer Funktionen berechnen

the accepted-warning registry now records the Niedersachsen-specific APV-202 for 858113c5-e53b-57bb-b01f-ba95c3ddcb6f

Why this cut:

this is the cleanest next NI follow-on after the derivative-graph step:
the source atom explicitly covers selected standard derivatives plus sum and factor rule
and the canonical target narrows that same route to elementary derivatives calculated with differentiation rules
the bridge remains reviewed partial because the NI wording is slightly narrower than the canonical atom and does not claim the full current shared elementary-function breadth
no new retained prerequisite bridge is needed here:
the already-open NI route through b42bdfcc-3db7-5697-8b3e-69e50962ca86 is sufficient for this rule-based leaf

Interpretation:

Niedersachsen upper-secondary math now reaches the first five shared canonical derivative-entry leaves through one bounded retained route
the next Niedersachsen step should now move to the next downstream NI analysis lane beyond this starter corridor rather than reopening lower-secondary work

2026-03-20: Niedersachsen upper-secondary reaches the first downstream extremal-problem leaf

What changed:

the Niedersachsen Sek-II mapping lane now carries a sixth reviewed row beyond the retained derivative-entry starter corridor:
d08d5280-3561-4d02-91f0-5f7465dd88a7 -> 1511b39a-4094-5450-a755-4a3ad3339733 as partial
the broad NI source atom Tangenten, Normalen, Monotonie, Extrem- und Wendestellen untersuchen und Sachprobleme loesen
is now reused once for the narrower shared canonical leaf Einfache Extremwertprobleme lösen
after applicability compilation, DE-NI is now also visible on the shared canonical Anwendungen des Ableitungsbegriffs cluster
the repository-backed Niedersachsen Sek-II fixture and upper-secondary mapping README were aligned to the new six-row state
the accepted-warning registry now records the Niedersachsen-specific APV-202 for 1511b39a-4094-5450-a755-4a3ad3339733

Why this cut:

this is the cleanest first downstream NI follow-on beyond the current derivative-entry starter route:
the source atom explicitly includes optimization use
and the canonical target narrows that same surface to simple extremal problems solved and interpreted in context
the bridge remains reviewed partial because the NI wording is broader and still bundles tangent / normal equations, monotonicity, and special-point analysis into the same clause
no new retained prerequisite bridge is needed here:
the already-open NI route through 845440ce-f63f-5835-903f-739145ca27bd and 858113c5-e53b-57bb-b01f-ba95c3ddcb6f is sufficient for this downstream leaf

full ./run_ci.sh passed after the NI downstream extremal-problem pass

Interpretation:

Niedersachsen upper-secondary math now reaches the first downstream E.3 application leaf without widening the retained prerequisite surface
the next Niedersachsen step should stay on the same broad NI AB3 source atom and decide whether a retained split is justified for tangent / monotonicity / Wendestellen follow-ons

2026-03-20: Niedersachsen retained-splits the downstream AB3 source atom and reaches the first-derivative investigation leaf

What changed:

the broad Niedersachsen Sek-II source atom d08d5280-3561-4d02-91f0-5f7465dd88a7
is no longer kept as one coarse atomic clause
it is now a retained split-cluster with three source-aligned children for:
- tangent / normal equations
- monotonicity plus Extrem- and Wendestellen
- optimization use
the existing extremal-problem bridge was repointed from the old broad parent to the narrower optimization child:
270b0f43-623c-413c-b7f1-eb690079ad8d -> 1511b39a-4094-5450-a755-4a3ad3339733 as partial
the Niedersachsen Sek-II mapping lane now carries a seventh reviewed row:
f4515a28-7161-49ae-8e74-f58d81ec0812 -> 350fc8b1-ead0-4239-b28a-217cbd3bd1c3 as partial
after applicability compilation, DE-NI is now also visible on the shared canonical leaf Monotonie und Extremstellen mit der ersten Ableitung untersuchen
the source membership / closure registries, the NI closure regression, the repository-backed Niedersachsen Sek-II fixture, and the upper-secondary mapping README were aligned to the retained-split seven-row state
the accepted-warning registry now records the Niedersachsen-specific APV-202 for 350fc8b1-ead0-4239-b28a-217cbd3bd1c3, and the NI rationale for 1511b39a-4094-5450-a755-4a3ad3339733 was narrowed to the new optimization child

Why this cut:

the previous NI AB3 source atom had become too broad for repeated downstream reuse:
it bundled tangents / normals, monotonicity, special points, and optimization in one clause
so another direct broad partial would have increased review debt without improving source precision
the retained split keeps the archived source landscape stable while making the next NI bridge source-tighter
the new monotonicity bridge remains reviewed partial because the retained NI child still combines extrema with Wendestellen rather than isolating the narrower first-derivative-only canonical leaf

npm run validate:view-filters remains at 0 errors, 3 warnings, 196 accepted warnings
full ./run_ci.sh passed after the NI retained-split monotonicity pass

Interpretation:

Niedersachsen upper-secondary math now reaches a second downstream E.3 application leaf without keeping the old coarse AB3 source atom in active bridge use
the next Niedersachsen step should stay inside this retained split:
either leave the tangent / normal child intentionally unmapped for now
or split the monotonicity / Wendestellen child once more before attempting a second-derivative follow-on

2026-03-21: Niedersachsen closes the retained tangent lane with one bounded shared-leaf bridge

What changed:

the retained Niedersachsen source child 23e03002-37c4-4268-ba3a-ddcdffc2e666
now maps as one reviewed partial
to the shared canonical tangent-equation leaf 0264591c-fdd7-41c6-9fb9-7cb3a03f7658
this closes the remaining open tangent-lane decision inside the retained NI AB3 split without introducing another source split
after applicability compilation, DE-NI is now also visible on the shared canonical leaf Tangentengleichungen und Steigungswinkel bestimmen and thereby on the surrounding tangents/normals cluster
the repository-backed Niedersachsen Sek-II fixture and upper-secondary mapping README were aligned to the new nine-row state
the accepted-warning registry now records the Niedersachsen-specific APV-202 for 0264591c-fdd7-41c6-9fb9-7cb3a03f7658

Why this cut:

the NI source child isolates tangent and normal equations cleanly enough to justify one bounded shared-leaf bridge
forcing another source split would not buy much:
the remaining mismatch is mainly the missing explicit Steigungswinkel surface
that is already narrow enough to live as reviewed partial debt
mapping to the shared tangent-equation leaf is cleaner than forcing another NI-only split:
the Bayern-derived tangent-equation leaf is closer to the NI wording than the NRW slope-focused leaf
the remaining mismatch is limited and reviewable: missing explicit Steigungswinkel on the source side, extra Normalengleichungen on the NI side

full ./run_ci.sh passed after the NI tangent-lane pass

Interpretation:

the retained NI E-phase derivative-usage starter slice is now closed without further source-shape debt inside the current pilot subset
the next Niedersachsen step should now move outside this retained starter slice:
either widen the NI upper-secondary source snapshot into the next corridor
or stop the NI pilot here and move to the next Bundesland

2026-03-21: Baden-Wuerttemberg mathematics mapping-lane setup opens the post-Niedersachsen Stage-B lane

What changed:

the next post-Niedersachsen onboarding lane is now prepared for DE-BW
the first real DE-BW canonical math mapping fixtures now exist at:
curricula/DE/Gymnasium/mapping/DE-BW/lower-secondary/bw_math_lower_secondary_to_canonical_math.json
curricula/DE/Gymnasium/mapping/DE-BW/upper-secondary/bw_math_upper_secondary_to_canonical_math.json
both fixtures are repository-backed and intentionally still empty (0 mappings)
stable Baden-Wuerttemberg source-landscape IDs are now reserved for the future source snapshots:
lower-secondary math: 6232b783-199c-4c50-92f2-9fb31277e619
upper-secondary math: fa8f864a-aac5-486d-8e77-40df2af038a3
the reservation and no-premature-activation rule now live in:
curricula/DE/Gymnasium/provenance/bw-math-onboarding.md
the new DE-BW mapping-lane READMEs record the planned lane purpose and current non-activated state

Why this cut:

the retained NI E-phase starter slice is now closed cleanly enough that the next reusable rollout learning step is no longer another local NI cleanup
Baden-Wuerttemberg is the cleanest remaining placeholder lane for repeating the early multi-state onboarding pattern once more:
one provider family
explicit math references for both lower-secondary and upper-secondary Gymnasium
a Kursstufe structure that should pressure-test the shared upper-secondary canonical spine differently from NRW and Niedersachsen
preparing the Stage-B lane first keeps the next move operationally simple:
source import can follow without reopening runtime or fixture semantics
the reserved IDs are now stable before any source snapshots are authored

Validation used:

./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
./run_ci.sh

the repository-backed Baden-Wuerttemberg upper-secondary mapping fixture parses cleanly with 0 rows
full ./run_ci.sh passed after the post-Niedersachsen Stage-B scaffold pass

Interpretation:

the next executable program step is now no longer a local NI tangent/derivative follow-on
the clean next move is Baden-Wuerttemberg Stage A:
archive the official mathematics source bundle under curricula/DE/Gymnasium/input/BW/
then build the first lower-secondary and upper-secondary source snapshots

2026-04-03: Bavaria upper-secondary retained-splits the matrix-power/fixed-vector source atom

What changed:

the broad Bavaria upper-secondary source atom:
ccd385d1-13f8-5b0a-bb7c-2c1428f6eaf3 is no longer treated as one archived atomic bundle
instead, the retained Bavaria source snapshot now resolves it through two child leaves:
c0959210-c934-4498-b94d-44c90b1a4ad1 (berechnen Potenzen von Matrizen und deuten diese bei mehrstufigen Prozessen)
0cb17a53-944d-47b7-9bac-2094e91793eb (bestimmen bei mehrstufigen Prozessen Fixvektoren und deuten diese im Sachzusammenhang)
the retained parent:
ccd385d1-13f8-5b0a-bb7c-2c1428f6eaf3 now stays in the Bavaria source file as a broad corridor node whose contains list points at those two new children
the archived Bavaria source registries were widened in place:
source-goal-membership-registry.json now includes both new retained child IDs
source-goal-closure-registry.json now resolves the broad parent through those two children instead of treating ccd385d1... as atomic
the Bavaria upper-secondary mapping lane now keeps the retained parent as a broad partial bridge to the shared canonical corridor:
d6d8904c-896f-5850-8181-06c223346b80 (Matrizen, Übergangsprozesse und lineare Modelle (Sek II))
the new matrix-power child:
c0959210-c934-4498-b94d-44c90b1a4ad1 now maps exact to:
33c6e64c-5955-5b07-85d4-74a97b19dd56 (Matrixpotenzen in Übergangsprozessen deuten)
the new fixed-vector child:
0cb17a53-944d-47b7-9bac-2094e91793eb now maps exact to:
8d893e63-d7de-52d9-8bcb-f48f47d1ccbf (Stabile Zustände mithilfe von Fixvektoren bestimmen)
the adjacent Bavaria absorption leaf:
532c66d0-f4f1-5689-b97d-025f7730da5d remains a broad partial bridge to:
0a024ecf-27ee-40a2-bf41-0e2faaeb1252 because this slice still has no cleaner one-to-one canonical target

Why this cut:

the original Bavaria source wording bundles two separable skills:
matrix powers for multi-step transition processes
fixed vectors as stable states
both subskills already have honest shared canonical atoms, so keeping one broad partial bridge would preserve unnecessary breadth mismatch
retaining the broad parent in the archived source tree keeps provenance stable while letting the learner-facing bridge become more exact
the adjacent absorption clause still mixes a different late-process interpretation surface and therefore should not be forced onto one of the two newly exact children

Validation used:

APPLICABILITY_APPLY_SCOPE=68a8ac50-f5f5-4e24-8aa9-5e408ca01ced npm --prefix app run apply:applicability

Validation result:

the applicability compiler persisted 1 landscape and changed 136 goals across 1 file in the canonical mathematics graph
npm --prefix app run validate:view-filters now reports 0 errors, 14 warnings, and 534 accepted warnings

Interpretation:

Bavaria upper-secondary mathematics now reaches the shared Sek-II matrix corridor through two exact source-backed leaves instead of one broad partial bridge
the clean move here was a retained split in the source lane, not a new canonical atom: the canonical corridor already had the right matrix-power and fixed-vector leaves
the remaining open decision in this micro-corridor is still the absorption / long-run behavior clause, which remains intentionally broad for now

2026-03-21: Baden-Wuerttemberg mathematics source import completes post-Niedersachsen Stage A

What changed:

the official Baden-Wuerttemberg Gymnasium mathematics source PDF is now archived locally at:
curricula/DE/Gymnasium/input/BW/BP2016BW_ALLG_GYM_M.pdf
this provider export currently covers both lower-secondary and Kursstufe mathematics in one official source bundle
the Baden-Wuerttemberg input lane README now records that shared archive state and points both math sections at the local file
lane-specific provenance notes now exist at:
curricula/DE/Gymnasium/input/BW/lower-secondary/references.md
curricula/DE/Gymnasium/input/BW/upper-secondary/references.md
the BW onboarding note now records that the source PDF is archived while the source registries still remain inactive until real snapshots exist

Why this cut:

the post-NI reusable next step was source onboarding for one further mathematics state, not more local NI corridor cleanup
Baden-Wuerttemberg exposes a slightly different source shape than NRW and Niedersachsen:
one official combined Gymnasium mathematics export instead of two separate Sek-I / Sek-II PDFs
archiving that official combined export first keeps the next Stage-C snapshot work grounded in a fixed on-disk source bundle before any source-goal IDs are authored

Validation used:

./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'

Validation result:

full ./run_ci.sh passed after the Baden-Wuerttemberg Stage-A source import
npm run validate:view-filters remains at 0 errors, 3 warnings, 198 accepted warnings

Interpretation:

Baden-Wuerttemberg is no longer a README-only placeholder lane
the next executable program step is now Baden-Wuerttemberg Stage C:
derive the first lower-secondary pilot snapshot from the archived combined mathematics PDF
then derive the first upper-secondary pilot snapshot from the same source bundle

2026-03-21: Baden-Wuerttemberg lower-secondary pilot source snapshot completes the first Stage-C activation

What changed:

the first real Baden-Wuerttemberg Sek-I source snapshot now exists at:
curricula/DE/Gymnasium/input/BW/lower-secondary/source-json/DE_BAW_S_GYM_1_MATHEMATIK.de.json.snapshot
the new archived source landscape uses the reserved Baden-Wuerttemberg lower-secondary math sourceLandscapeId:
6232b783-199c-4c50-92f2-9fb31277e619
the first imported BW pilot subset is deliberately small and source-led:
the curriculum-wide orientation layer from 1.1 Bildungswert des Faches Mathematik
3.1.4 Leitidee Funktionaler Zusammenhang in Klassen 5/6
3.2.4 Leitidee Funktionaler Zusammenhang in Klassen 7/8
the lower-secondary Baden-Wuerttemberg source lane is now active in shared provenance:
curricula/DE/Gymnasium/provenance/source-landscape-registry.json
curricula/DE/Gymnasium/provenance/source-goal-membership-registry.json
curricula/DE/Gymnasium/provenance/source-goal-closure-registry.json
the local BW source inventory now also includes:
curricula/DE/Gymnasium/input/BW/math-structure-note.md
archived-source runtime handling and test coverage were widened for Baden-Wuerttemberg:
backend/src/main/java/com/skillpilot/backend/landscape/LandscapeService.java
backend/src/test/java/com/skillpilot/backend/landscape/LandscapeServiceTest.java

Why this cut:

after BW Stage A and Stage B, the next reusable step was no longer repository setup but a first real archived source landscape with stable source goal IDs
the lower-secondary shared functions corridor is the cleanest first Baden-Wuerttemberg subset because the combined source PDF already exposes it in a form close to the earlier NRW and Niedersachsen onboarding cuts
activating provenance at this point keeps the later BW mapping work grounded in repository-backed source IDs instead of PDF-only references

Validation used:

./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
npm run validate:graph
./run_ci.sh

Validation result:

the new Baden-Wuerttemberg lower-secondary pilot source landscape loads from the real registry
its archived atomic closure resolves correctly for the first BW functions corridor
full ./run_ci.sh passed after the new snapshot, provenance activation, and test coverage
npm run validate:view-filters remains at 0 errors, 3 warnings, 198 accepted warnings

Interpretation:

Stage C is now complete for the first Baden-Wuerttemberg lower-secondary pilot subset
Baden-Wuerttemberg upper-secondary remains source-PDF-only for now
the next Baden-Wuerttemberg blocker is therefore narrower than before:
import the first BW upper-secondary source snapshot with stable source goal IDs
then activate the shared provenance registries for that upper-secondary lane

2026-03-21: Baden-Wuerttemberg course-stage pilot source snapshot completes the first upper-secondary Stage-C activation

What changed:

the first real Baden-Wuerttemberg Kursstufe source snapshot now exists at:
curricula/DE/Gymnasium/input/BW/upper-secondary/source-json/DE_BAW_S_GYM_2_MATHEMATIK.de.json.snapshot
the new archived source landscape uses the reserved Baden-Wuerttemberg upper-secondary math sourceLandscapeId:
fa8f864a-aac5-486d-8e77-40df2af038a3
the first imported BW Kursstufe pilot subset is deliberately small and source-led:
the shared orientation layer from 1.4 Basisfach und Leistungsfach in der Oberstufe
3.5.4 Leitidee Funktionaler Zusammenhang in Basisfach
3.4.4 Leitidee Funktionaler Zusammenhang in Leistungsfach
the upper-secondary Baden-Wuerttemberg source lane is now also active in shared provenance:
curricula/DE/Gymnasium/provenance/source-landscape-registry.json
curricula/DE/Gymnasium/provenance/source-goal-membership-registry.json
curricula/DE/Gymnasium/provenance/source-goal-closure-registry.json
archived-source runtime handling and test coverage were widened again for Baden-Wuerttemberg:
backend/src/main/java/com/skillpilot/backend/landscape/LandscapeService.java
backend/src/test/java/com/skillpilot/backend/landscape/LandscapeServiceTest.java

Why this cut:

after the first BW Sek-I Stage-C activation, the next reusable source step was the matching Kursstufe lane from the same archived combined PDF
Baden-Wuerttemberg now has enough real source structure on disk to avoid further PDF-first reasoning for the first mapping pass
the imported Basisfach/Leistungsfach pair gives the rollout a fifth upper-secondary comparison shape after Hessen, Bavaria, NRW, and Niedersachsen without forcing an early broad subject import

Validation used:

npm run validate:graph
./gradlew test --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest' --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
./run_ci.sh

Validation result:

the first BW Kursstufe pilot snapshot parses cleanly and is now reachable through the shared archived-source registries
full ./run_ci.sh passed after the BW Kursstufe Stage-C activation
npm run validate:view-filters remains at 0 errors, 3 warnings, 198 accepted warnings

Interpretation:

Baden-Wuerttemberg is no longer source-incomplete on the mathematics-first rollout track
the clean next program step is now no longer another BW source snapshot
the next executable work item is the first reviewed BW lower-secondary function-corridor mapping pass against the already archived Sek-I source IDs

2026-03-21: Niedersachsen retained-splits the monotonicity/Wendestellen child and reaches the second-derivative curvature leaf

What changed:

the retained Niedersachsen source child f4515a28-7161-49ae-8e74-f58d81ec0812
is no longer kept as one broad atomic clause
it is now a retained split-cluster with two narrower children for:
- monotonicity plus Extremstellen
- Wendestellen
the existing first-derivative bridge was repointed from the broader first-stage child to the narrower monotonicity/extrema child:
22074d55-5227-4487-9fcc-4bc5dcec970e -> 350fc8b1-ead0-4239-b28a-217cbd3bd1c3 as partial
the Niedersachsen Sek-II mapping lane now carries an eighth reviewed row:
d3e91530-938e-46c9-b0de-55bbae83e5a0 -> b3604df4-15a8-41c8-a8b0-50dadd698bd3 as partial
after applicability compilation, DE-NI is now also visible on the shared canonical leaf Krümmung und Wendestellen mit der zweiten Ableitung untersuchen
the source membership / closure registries, the NI closure regression, the repository-backed Niedersachsen Sek-II fixture, and the upper-secondary mapping README were aligned to the retained-split eight-row state
the accepted-warning registry now records the Niedersachsen-specific APV-202 for b3604df4-15a8-41c8-a8b0-50dadd698bd3, and the NI rationale for 350fc8b1-ead0-4239-b28a-217cbd3bd1c3 was narrowed to the new monotonicity/extrema child

Why this cut:

the first retained NI child was still too broad for a clean second-derivative follow-on:
it bundled monotonicity, extremal behavior, and Wendestellen in one clause
so reusing it again would have stacked another broad partial on top of already reviewed debt
the second retained split keeps the archived NI source lane stable while making the first- and second-derivative bridges materially tighter
the new second-derivative bridge still remains reviewed partial because the retained NI Wendestellen child does not isolate the full canonical curvature surface or the contextual interpretation layer

Validation used:

npm run validate:graph
./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest' --tests 'com.skillpilot.backend.landscape.LandscapeServiceTest'
npm run apply:applicability
npm run validate:view-filters
./run_ci.sh

Validation result:

the Niedersachsen Sek-II repository mapping fixture now parses cleanly with 8 rows
the NI upper-secondary source closure regression now resolves the first retained child to its two narrower atomic children
npm run apply:applicability changed 1 goal across 1 file while compiling the NI second-derivative curvature bridge
npm run validate:view-filters remains at 0 errors, 3 warnings, 197 accepted warnings
full ./run_ci.sh passed after the NI retained-split second-derivative pass

Interpretation:

Niedersachsen upper-secondary math now reaches the shared second-derivative curvature leaf without forcing another reuse of the broad first-stage retained child
the next Niedersachsen step should now decide only the remaining tangent-lane question:
either leave the tangent / normal child intentionally unmapped for now
or accept one bounded reviewed partial onto the shared tangents leaf

2026-03-20: Niedersachsen upper-secondary reaches the first shared E.2 change-rate leaf

What changed:

the Niedersachsen Sek-II mapping lane now carries its first reviewed row instead of staying empty:
250ba641-b2a1-4717-9a27-4ee0e6aa83c2 -> ae20183e-92b5-5521-b8e0-9a8662cf51f5 as partial
this is the same conservative first upper-secondary Analysis cut previously proven in NRW:
the NI source atom Mittlere und lokale Aenderungsraten sowie Sekanten- und Tangentensteigungen bestimmen
is reused once for the narrower shared canonical leaf Mittlere Änderungsrate berechnen und deuten
after applicability compilation, DE-NI is now visible on the first shared upper-secondary derivative-entry leaf and pulls the shared canonical derivative-entry cluster into Niedersachsen as well
the repository-backed Niedersachsen Sek-II fixture and upper-secondary mapping README were aligned to the new one-row state
the accepted-warning registry now records:
the Niedersachsen-specific APV-202 for ae20183e-92b5-5521-b8e0-9a8662cf51f5
two matching retained-prerequisite APV-201 entries for c65ecabf-d00b-4e2d-99ae-b64692325ffb and a8c42ee9-2898-4247-819f-c235032ac78a
the canonical function-value leaves c65ecabf-d00b-4e2d-99ae-b64692325ffb and a8c42ee9-2898-4247-819f-c235032ac78a now carry explicit retained DE-NI applicability so the first derivative-entry route can compile cleanly

Why this cut:

the imported NI upper-secondary corridor is still intentionally narrow, and the broadest derivative bundle would be too coarse as a first kept bridge
the cleanest reusable move is the same one that worked in NRW:
start with the average-rate entry leaf
do not force the next derivative follow-on until the route is visible and validated
the NI source wording is still broader than the canonical average-rate atom because it also includes local rates and secant / tangent slopes, so the bridge is intentionally kept as reviewed partial
the NI pilot source still does not isolate one-to-one legacy atoms for the two shared function-value prerequisites, so those two prerequisite closures are intentionally documented as retained APV-201 bridges instead of being forced into weak new partial mappings

Validation used:

npm run validate:graph
./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
npm run apply:applicability
npm run validate:view-filters
./run_ci.sh

Validation result:

the Niedersachsen Sek-II repository mapping fixture now parses cleanly with 1 row
npm run apply:applicability changed 2 goals across 1 file while compiling the first NI upper-secondary derivative-entry route:
the two retained NI prerequisite leaves for direct and graph-based function-value work
npm run validate:view-filters remains at 0 errors, 3 warnings, 190 accepted warnings
full ./run_ci.sh passed after the NI upper-secondary change-rate bridge pass

Interpretation:

Niedersachsen upper-secondary math is now active on the shared canonical Analysis spine beyond source-only readiness
the first NI E.2 route is now open, but only with the two explicit retained function-value prerequisite bridges documented in the accepted-warning registry
the next Niedersachsen step should stay in the same upper-secondary E.2 corridor:
either 234dde5d-cc9d-4508-af9e-092e614ea304 against the next derivative-entry atom
or a small retained NI source split if that follow-on alignment turns out too broad

2026-03-20: NRW upper-secondary Q1.1 gains an exact area-function leaf

What changed:

the canonical Q1.1 introduction cluster:
93ac7fc8-6d83-5394-bbea-80758b463da1 now also contains the new NRW-backed leaf:
9441bb35-2a2f-4edc-9d8a-bc58c257054d (Graphen von Flächeninhaltsfunktionen skizzieren)
the NRW upper-secondary source atom:
371359c2-6e29-4863-879f-d53b044204ce now maps exact to that new canonical leaf
the repository-backed NRW upper-secondary mapping lane now carries 24 rows instead of 23
the canonical cluster weights were advanced along the affected ancestor chain:
Q1.1 Einführung in die Integralrechnung
Q1 Analysis – Integralrechnung und Differenzialgleichungen
root Mathematik

Why this cut:

the imported NRW source clause is specific, assessable, and no longer just a retained open question in the integral corridor
there was still no canonical leaf for sketching area-function graphs; keeping the clause unmapped would have preserved an artificial source gap even though the source wording is already clean enough for a leaf-level canonical atom
the adjacent Hessen-only exp/log follow-on atom c72a8032-71f6-56ed-a896-06ae435ff2ec still has no comparably clean NRW source counterpart, so the better move here was to close the real NRW source gap instead of forcing another cross-state split

Validation used:

npm run validate:graph
./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
npm run apply:applicability
npm run validate:view-filters
./run_ci.sh

Validation result:

the repository-backed NRW upper-secondary mapping fixture now parses cleanly with 24 rows
npm run apply:applicability changed 0 goals across 0 files because the new NRW area-function leaf already carried explicit applicability metadata
npm run validate:view-filters remains at 0 errors, 3 warnings, 184 accepted warnings
full ./run_ci.sh passed after the NRW upper-secondary area-function step

Interpretation:

NRW upper-secondary math now reaches the previously retained Flächeninhaltsfunktions-Klausel through an exact canonical Q1.1 leaf instead of leaving it as archived but unmapped source material
the next clean NRW source-led decision is now the remaining broad E-phase atom 22e2cc01-be7c-4478-8d22-0409ff5b14a0 (Eigenschaften ganzrationaler Funktionen bestimmen), not the Hessen-only exp/log follow-on leaf

2026-03-20: NRW upper-secondary inverse-function lane closes the natural-logarithm breadth mismatch

What changed:

the canonical LK atom:
392440db-6a43-59c0-a48d-958128fa16a8 is no longer a single mixed-surface leaf for Hessen and NRW
instead, it is now a small mixed-state cluster with:
1e26404a-93ef-45f3-a28c-15679fbae96b for the Hessen-exact leaf Natürlichen Logarithmus als Umkehrfunktion verstehen (LK)
c15fe32d-1c83-4127-b1a4-9125af3d8f5d for the NRW-exact leaf Umkehrbarkeit ausgewählter Funktionen untersuchen und einfache Umkehrfunktionen bestimmen
the Hessen mapping:
d603080f-0268-4da1-811a-b55ed05665ba was repointed to the retained HE leaf
the NRW mapping:
85be691c-c569-4cdf-b332-b9d77d47666d is now exact instead of partial
the obsolete NRW APV-202 entry for:
392440db-6a43-59c0-a48d-958128fa16a8 was removed from the accepted-warning registry

Why this cut:

the NRW source clause explicitly covers invertibility checks and simple inverse-function terms for selected functions, especially e^x and ln(x)
the old canonical leaf was narrower and Hessen-specific in emphasis: deriving ln(x) from the inverse-function relation and solving simple exponential equations
a small retained split removes the reviewed breadth mismatch without forcing the Hessen-specific ln surface onto NRW or broadening the Hessen leaf away from its source

2026-03-20: NRW upper-secondary inverse-graph lane closes through an exact wording cut

What changed:

the canonical NRW-only inverse-graph leaf:
dbc13bb0-963b-49a8-a441-2183f4b64c8e was narrowed to the actual NRW source surface and no longer carries the stronger reflection-specific wording
the NRW upper-secondary source atom:
e0c4432f-fc34-48c2-84d8-0e998b978500 now maps exact instead of partial
the obsolete NRW APV-202 entry for:
dbc13bb0-963b-49a8-a441-2183f4b64c8e was removed from the accepted-warning registry
the repository-backed mapping fixture was aligned to the exact cut, and one stale earlier exact expectation in the same NRW upper-secondary lane was corrected while closing the fixture drift

Why this cut:

the NRW source clause isolates the relation between function graph and inverse graph, but it does not explicitly require the stronger reflection-at-y=x justification that had remained in the canonical wording
because dbc13bb0-963b-49a8-a441-2183f4b64c8e was already the NRW-only leaf after the previous retained split, the cleaner move was to narrow that leaf to the source wording instead of adding another canonical child

Validation used:

npm run validate:graph
./gradlew test --tests 'com.skillpilot.backend.landscape.GoalMappingRepositoryFixtureTest'
npm run apply:applicability
npm run validate:view-filters
./run_ci.sh

Validation result:

the repository-backed NRW upper-secondary mapping fixture still parses cleanly with 23 rows
npm run apply:applicability changed 0 goals across 0 files because the canonical applicability state was already consistent; this step closed the repository-backed mapping and accepted-warning debt
npm run validate:view-filters now reports 0 errors, 3 warnings, 184 accepted warnings
full ./run_ci.sh passed after the NRW upper-secondary inverse-graph exact cut

Interpretation:

NRW no longer reaches the inverse-graph lane through a reviewed breadth mismatch; it now lands on an exact source-aligned canonical leaf
the next clean NRW decision can return to the adjacent LK exp/log corridor and decide whether c72a8032-71f6-56ed-a896-06ae435ff2ec should remain HE-only or receive a shared follow-on split

Validation result:

the repository-backed NRW upper-secondary mapping fixture still parses cleanly with 23 rows
npm run apply:applicability changed 0 goals across 0 files because the split was modeled directly in the canonical graph and mappings
npm run validate:view-filters now reports 0 errors, 3 warnings, 185 accepted warnings

Interpretation:

NRW no longer reaches the natural-logarithm leaf through a reviewed breadth mismatch; it now lands on its own exact LK inverse-function leaf
Hessen keeps its narrower exact ln-as-inverse surface instead of being widened down to the NRW wording
the next clean NRW decision in the same lane is now the downstream inverse-graph atom dbc13bb0-963b-49a8-a441-2183f4b64c8e, which still rests on a reviewed partial

Validation result:

the repository-backed NRW upper-secondary mapping fixture still parses cleanly with 23 rows
npm run apply:applicability changed 0 goals across 0 files because the split was modeled directly in the canonical graph and mappings
npm run validate:view-filters now reports 0 errors, 3 warnings, 186 accepted warnings
full ./run_ci.sh passed after the NRW upper-secondary tangent/angle split

Interpretation:

NRW no longer reaches the old tangent-equation atom through a reviewed breadth-mismatch; it now lands on its own exact E-phase leaf
Bavaria keeps its exact tangent-equation surface instead of being broadened down to the NRW wording
the next clean NRW decision can return to the adjacent LK exp/log lane and decide whether c72a8032-71f6-56ed-a896-06ae435ff2ec should remain HE-only or receive a shared follow-on split

Validation result:

the repository-backed NRW upper-secondary mapping fixture now parses cleanly with 22 rows
npm run apply:applicability changed 1 goal across 1 file: the retained canonical parameter cluster e7c9a459-52d1-5e29-8714-2b038c4d3a7f now compiles DE-NW visibility through child-union
npm run validate:view-filters remains at 0 errors, 3 warnings, 187 accepted warnings
full ./run_ci.sh passed after the NRW upper-secondary parameter-corridor step

Interpretation:

NRW upper-secondary math now reaches the shared Q2.1 parameter corridor through two exact source-backed leaves instead of forcing the already imported NRW clauses onto the old broad Hessen atom
the clean move here was a retained cluster split that keeps Hessen exact, gives NRW one exact GK/shared parameter-determination leaf plus one exact LK function-family leaf, and avoids adding fresh accepted-warning debt
the cleaner next NRW move is now the adjacent LK clause d9121fe6-058a-4ab8-a8ce-68d6eefea520 (Produktregel, Kettenregel und zusammengesetzte Funktionen nutzen) in the same retained 2.4.2 corridor

2026-03-20: NRW upper-secondary reaches the shared LK product-/chain-rule leaf

What changed:

the canonical Q2.1 cluster:
5ebfc509-0b4c-5c60-befb-2477eb24d4b5 now also contains the new LK leaf:
899ed286-0cc2-4d6d-ba46-7d4e40a11f41 (Produktregel, Kettenregel und zusammengesetzte Funktionen nutzen (LK))
that new canonical leaf was added directly instead of forcing the NRW LK clause onto the Hessen-only exp/log-combination atom:
c72a8032-71f6-56ed-a896-06ae435ff2ec
the NRW upper-secondary source atom:
d9121fe6-058a-4ab8-a8ce-68d6eefea520 now maps exact to the new canonical LK leaf
the NRW upper-secondary mapping lane now carries 23 rows instead of 22
no new accepted-warning entries were needed for this slice; the new LK rule/application lane closes through an exact mapping

npm run validate:view-filters remains at 0 errors, 3 warnings, 187 accepted warnings
full ./run_ci.sh passed after the NRW upper-secondary LK product-/chain-rule step

Interpretation:

NRW upper-secondary math now reaches not only the shared parameter and inverse-function corridor in Q2.1, but also an explicit LK technique leaf for product rule, chain rule, and composed functions
the clean move here was a small new canonical LK leaf: the NRW source clause is broader than a pure derivative-rule atom, but still not aligned enough to justify widening the Hessen-only exp/log-combination leaf
the next NRW decision should stay in the same LK corridor and examine whether the adjacent Hessen-only atom c72a8032-71f6-56ed-a896-06ae435ff2ec now justifies a shared follow-on split, or should remain HE-only for the moment

2026-03-20: NRW upper-secondary tangent/angle lane closes through an exact split

What changed:

the canonical E-phase tangent atom:
bb979dbd-b080-432c-8cf1-067ba6eff381 is no longer a single mixed-surface leaf for Bavaria and NRW
instead, it is now a small mixed-state cluster with:
0264591c-fdd7-41c6-9fb9-7cb3a03f7658 (Tangentengleichungen und Steigungswinkel bestimmen) for the Bavaria-exact surface
6aed5be9-f62f-482a-9b98-4253c3275e6e (Sekanten-, Tangenten- und Normalensteigungen mit Steigungswinkeln bestimmen) for the NRW-exact surface
the Bavaria mapping:
28e3394e-90d7-5812-8b7b-2c55558468ad was repointed from the old shared atom to the new Bavaria-exact child
the NRW mapping:
43b21038-8dbb-4f85-ab8e-898a9cef38fb is now exact instead of partial
the obsolete NRW APV-202 entry for:
bb979dbd-b080-432c-8cf1-067ba6eff381 was removed from the accepted-warning registry

Why this cut:

the NRW source clause explicitly covers secant, tangent, and normal slopes plus slope angles, but not tangent equations
the Bavaria source clause explicitly covers tangent equations plus slope angles
a small canonical split removes the reviewed breadth-mismatch without weakening either source surface

2026-04-14: Niedersachsen Physics widens the E-phase dynamics lane onto energy and experiments

What changed:

the Niedersachsen upper-secondary Physics source snapshot:
730a6dbb-7ddb-486b-8ac8-dd9e58e3d113 now also contains the adjacent E-phase source cluster:
4d00b658-4c32-4123-96e3-779a186ab031 (Einfuehrungsphase: Dynamik - Energie und Experimente)
that new source strip imports four new leaves from the same KC Dynamik pages:
292f99ef-0bd8-43df-b9a8-bf47d3293bd1 (Kinetische Energie nennen und in einfachen Situationen berechnen)
1f1f08e8-2845-4758-ae2f-f977748d0b5d (Energieerhaltungssatz der Mechanik formulieren und in einfachen Situationen nutzen)
c53ea281-1bfb-4e97-8a2a-a81b023ded24 (Einfache Experimente zum Energieerhaltungssatz planen, durchfuehren und dokumentieren)
e4bafbf9-6875-4129-9e40-4aa6a6b35402 (Energienutzung und Nachhaltigkeit mit einem einfachen Bewertungsverfahren einordnen)
the repository-backed Niedersachsen Physics mapping lane:
curricula/DE/Gymnasium/mapping/DE-NI/upper-secondary/ni_physics_upper_secondary_to_canonical_physics.json now carries 12 reviewed rows instead of 9
the three new reviewed bridges are:
292f99ef-0bd8-43df-b9a8-bf47d3293bd1 -> 7eeff2de-6015-49a6-a96e-a488d886dc9f (Kinetische Energie) (partial)
1f1f08e8-2845-4758-ae2f-f977748d0b5d -> 91c49019-ea51-4ce5-a919-c91c45b25e83 (Energieerhaltung) (partial)
c53ea281-1bfb-4e97-8a2a-a81b023ded24 -> 91c49019-ea51-4ce5-a919-c91c45b25e83 (Energieerhaltung) (partial)
the fourth new Niedersachsen source leaf:
e4bafbf9-6875-4129-9e40-4aa6a6b35402 stays intentionally source-led, because the currently available shared thermodynamics evaluation goals would overclaim the narrower Niedersachsen wording on a simple Bewertungsverfahren around Energienutzung and Nachhaltigkeit

Why this cut:

the active Niedersachsen Physics lane was already anchored on the shared E-phase Dynamik strip, and the next clean adjacent move on the same KC pages was the energy/experiment surface on page 28
the three new mapped leaves land conservatively on already existing shared canonical energy goals, so the widening does not need new canonical Physics atoms
the sustainability-related Bewertungsblatt was imported into the source snapshot to keep provenance honest, but not forced onto the broader thermodynamics/climate evaluation surface before wider reviewed evidence exists

Validation used:

python3 scripts/render_canonical_physics_bundesland_status.py

Interpretation:

Niedersachsen upper-secondary Physics now reaches not only the shared E-phase motion strip but also the first adjacent shared energy strip on Kinetische Energie and Energieerhaltung
the clean move here was to keep the widening on the same explicit KC pages and to avoid inventing a premature Niedersachsen-specific learner-facing view or new canonical Physics atoms
the next clean Niedersachsen move should now leave the exhausted E-phase mechanics starter and open the first equally explicit qualification-phase anchor such as Elektrizitaet or Schwingungen und Wellen, unless the remaining sustainability-only Bewertungsblatt is intentionally resolved first

2026-04-14: Niedersachsen Physics opens the first qualification-phase electricity anchor

What changed:

the Niedersachsen upper-secondary Physics source snapshot:
730a6dbb-7ddb-486b-8ac8-dd9e58e3d113 now also contains the first qualification-phase source cluster:
f32b91d4-8691-408c-9417-8e34e4e3d87b (Qualifikationsphase: Elektrizitaet - Potenzial und Kondensator)
that new source strip imports seven new leaves from the Niedersachsen Elektrizitaet pages:

Why this cut:

the active Niedersachsen Physics lane had reached the limit of the initial E-phase mechanics starter, so the next clean widening needed to leave the same KC page pair and open the first equally explicit qualification-phase surface
the Niedersachsen wording on pages 33-34 aligns conservatively with already existing shared canonical Q1 electricity goals, so the widening can stay within the current canonical Physics graph without inventing Niedersachsen-specific atoms
the magnetische-Felder / Lorentzkraft / Wien-Filter strip on the following page is clearly adjacent, but it is a better follow-on after the field/potential/capacitor base has been opened explicitly

Interpretation:

Niedersachsen upper-secondary Physics now reaches not only the shared E-phase motion and energy strip but also the first shared Q1 electricity strip on current/voltage/potential/capacitor surfaces
the clean move here was to open the qualification-phase route without broadening into magnetische Felder or inventing new canonical Physics atoms
the next clean Niedersachsen move should now stay on this opened qualification-phase route and go deeper into Elektrizitaet (magnetische Felder, Lorentzkraft, Wien-Filter) or, if a parallel anchor is more useful, open Schwingungen und Wellen

0966258c-1eaa-4c41-8311-17352dcf0ec1 stay intentionally source-led, because the current shared canonical graph does not yet isolate a reviewed crossed-field/Wien-Filter target or the narrower eA Fadenstrahlrohr target

Why this cut:

after opening the first Niedersachsen Q1 potential/capacitor strip, the next equally explicit adjacent KC move was the page-35 magnetic-field/electron-trajectory surface, not yet the broader page-36 induction layer
the reviewed part of this source strip lands conservatively on already existing shared magnetic-field goals, so the widening still does not need new canonical Physics atoms
the crossed-field and Fadenstrahlrohr clauses were imported into the source snapshot to keep provenance honest, but left unmapped because the current shared canonical Physics graph does not yet expose a sufficiently narrow reviewed target

Interpretation:

Niedersachsen upper-secondary Physics now reaches not only the shared Q1 potential/capacitor strip but also the first shared magnetic-field strip on field-line description, conductor force, Lorentzkraft, and simple charged-particle motion
the clean move here was to keep widening on the same explicit KC route while leaving crossed-field/Wien-Filter and Fadenstrahlrohr residues source-led
the next clean Niedersachsen move should now most plausibly open the adjacent page-36 Induktion strip (Hallsonde, Spule, Induktionsspannung) or revisit the current source-led residues only if broader reviewed shared targets become justified

Why this cut:

after the reviewed page-35 magnet-field strip, the next equally explicit adjacent KC move was the page-36 induction surface on coils, Hall-probe measurements, first flux-based induction, and one simple induction application
all six reviewed bridges land on already existing shared canonical magnetic-field or induction targets, so the widening stays inside the current canonical Physics graph and does not justify new Niedersachsen-specific atoms
the imported page-36 source is still only partially exhausted: narrower eA residue around Hall voltage, differential/sinusoidal induction, and self-induction exists, but was not forced into the current wider shared targets

Interpretation:

Niedersachsen upper-secondary Physics now reaches not only the shared Q1 electricity and magnetic-field strip but also the first shared induction strip on coil fields, flux-based induction, induction-law reading, and one simple technical application
the clean move here was to keep widening on the same explicit KC route while still avoiding new canonical Physics atoms or Niedersachsen-specific composition views
the next clean Niedersachsen move should now either continue on the remaining page-36 eA induction residue (Hallspannung, differential/sinusoidal induction, Selbstinduktion) or open a parallel reviewed anchor such as Schwingungen und Wellen

Why this cut:

after the reviewed page-36 GK strip was open, the remaining adjacent source work was no longer a new thematic route but only the LK residue on Hallspannung, differential-form induction, self-induction, and magnetic field energy
those four clauses now land conservatively on already existing shared LK atoms, so the NI lane closes the page-36 route without inventing new canonical Physics atoms
this also removes the need to keep pointing at a still-open page-36 eA remainder in the rollout tracker; the next clean move can now leave Elektrizitaet

Interpretation:

Niedersachsen upper-secondary Physics now closes the full reviewed page-36 electricity route from coil fields and first induction up to the available shared LK follow-on leaves
the clean move here was to keep the widening on the same explicit KC page while still avoiding new canonical Physics atoms or Niedersachsen-specific composition views
the next clean Niedersachsen move should now leave Elektrizitaet and open Schwingungen und Wellen; the older Querfeld/Wien-Filter and Fadenstrahlrohr residues remain optional cleanup only if broader reviewed shared targets become justified

Why this cut:

after the reviewed Elektrizitaet route was exhausted, the next equally explicit source move was no longer another electricity cleanup but the first narrow Q2 Schwingungen surface on pages 37-38
the imported source already aligns conservatively with existing shared Q2 oscillation leaves, so the corridor can widen without inventing new canonical Physics atoms
keeping Wellen separate preserves a clean next move instead of mixing two adjacent but still distinguishable source surfaces into one oversized NI cut

Interpretation:

Niedersachsen upper-secondary Physics now reaches the first shared Q2 oscillation strip while still keeping the active lane narrow, reviewed, and free of Niedersachsen-specific canonical atom authoring
the clean move here was to open only Schwingungen, not immediately the adjacent Wellen surface, because the source still separates mechanical/electromagnetic oscillations from the later interference and wave-phenomena blocks
the next clean Niedersachsen move should now continue from this opened Q2 strip onto Wellen; the older Querfeld/Wien-Filter and Fadenstrahlrohr residues remain optional cleanup only if broader reviewed shared targets become justified

2026-04-15: Niedersachsen Physics exacts no new atom but closes the Michelson residue on the shared interferometer surface

What changed:

the repository-backed Niedersachsen Physics mapping lane:
curricula/DE/Gymnasium/mapping/DE-NI/upper-secondary/ni_physics_upper_secondary_to_canonical_physics.json now carries 54 reviewed rows instead of 53
one new reviewed bridge was added:
35bbb17f-d9be-4e2e-ab00-86f8d52d7cb0 (Michelson-Interferometer zum Nachweis kleiner Laengenaenderungen einordnen) -> d1e26b52-78a7-5f3b-ac9f-97f3e62d7db1 (Interferometer verstehen) (partial)
no Niedersachsen source snapshot widening was needed in this step:
the retained NI Michelson atom was already present inside the imported Wellen strip
no new canonical Physics atom was introduced:
the move reuses the existing shared Q3 leaf Interferometer verstehen
after applicability compilation, DE-NI is now also visible on:
d1e26b52-78a7-5f3b-ac9f-97f3e62d7db1 (Interferometer verstehen)
and thereby also on the parent clusters Elektromagnetische Wellen and Q3 Elektromagnetische Wellen und Quantenphysik
thirteen Niedersachsen-specific APV-202 entries are now documented for the widened NI Wellen/Michelson surface:
seven shared Physics wave/optics leaves: cb0ced6d-b7c1-5b7d-9922-8c394f6030e8, d716a35e-e422-5aba-b39a-f2e22f1e1e74, d5772db3-120c-5c37-ab46-2336d02236b0, 91683676-01cf-5003-80fa-a04d043b4e61, 4a7cbe83-b694-57d3-85ce-1eeca418daaf, 549269d3-1aef-5c55-9640-ee2a8e2ee9a1, 81c0d811-e6de-5489-8415-3b257c734a2e
five shared cross-subject math prerequisites pulled by the same optics route: c1f50bcc-7848-4e49-b9de-0ec030cc6bca, af3d6bff-c5fb-4ec6-a9f0-c0be09fc9186, e322310f-f33a-485d-bc23-2412a6b8fa12, 9023226b-fc17-412b-807c-2bb45cd551d5, a7ccb7a9-6fb0-4e2d-b6e0-6420cc5ae0bf
plus the new interferometer leaf d1e26b52-78a7-5f3b-ac9f-97f3e62d7db1

Why this cut:

after the reviewed NI Wellen strip, the only remaining source-led residue on that already opened topic row was the imported Michelson leaf
unlike the still source-led Querfeld/Wien-Filter and Fadenstrahlrohr residues, the canonical Physics graph now already exposes a sufficiently narrow reviewed target with Interferometer verstehen
this closes the active NI Schwingungen/Wellen row without forcing Niedersachsen-specific canonical atom growth

python3 scripts/render_canonical_physics_bundesland_status.py

Interpretation:

Niedersachsen upper-secondary Physics now closes the first retained Schwingungen/Wellen row on the active topic-first maintenance surface without introducing new canonical atoms or Niedersachsen-specific composition views
the clean move here was to reuse the already existing shared interferometer leaf instead of keeping Michelson source-led longer than necessary
the remaining NI source-led Physics residues are now only the earlier Querfeld/Wien-Filter and Fadenstrahlrohr clauses

2026-04-15: Niedersachsen Physics reuses the shared electric-field particle-motion leaf for the crossed-field follow-on

What changed:

the repository-backed Niedersachsen Physics mapping lane:
curricula/DE/Gymnasium/mapping/DE-NI/upper-secondary/ni_physics_upper_secondary_to_canonical_physics.json now carries 55 reviewed rows instead of 54
one new reviewed bridge was added:

no Niedersachsen source snapshot widening was needed in this step:
the retained crossed-field / Wien-Filter atom was already present inside the imported qualification-phase Elektrizitaet strip
no new canonical Physics atom was introduced:
the move reuses the existing shared Q1 leaf Geladene Teilchen in homogenen elektrischen Feldern untersuchen
after applicability compilation, DE-NI is now also visible on:
741774ef-15fc-4bcf-a370-e2c5cf4257d0 (Geladene Teilchen in homogenen elektrischen Feldern untersuchen)
and thereby also on the parent clusters 47f76c5c-05d1-59eb-876d-cafb98a66c5b (Bewegung geladener Teilchen im elektrischen Feld) and 43eb9b9e-cfdf-5cf1-88db-87391c7ba595 (Ladungen in Feldern)
one new Niedersachsen-specific APV-202 entry is now documented for the widened NI crossed-field surface:
741774ef-15fc-4bcf-a370-e2c5cf4257d0

Why this cut:

unlike the still source-led eA Fadenstrahlrohr residue, the non-eA crossed-field clause already overlaps enough with the shared reviewed Q1 electric-field particle-motion leaf
the reviewed NI wording stays narrower than the canonical target because it focuses on free electrons plus Wien-Filter context, not the full broader charged-particle and energy-change surface, so partial is the defensible match
this closes the retained non-eA Querfeld / Wien-Filter residue without forcing Niedersachsen-specific canonical atom growth

Interpretation:

Niedersachsen upper-secondary Physics now closes the retained non-eA crossed-field follow-on on its active qualification-phase Elektrizitaet route without introducing new canonical atoms or Niedersachsen-specific composition views
the only remaining NI source-led Physics residue is now the narrower eA Fadenstrahlrohr clause

2026-04-15: Niedersachsen Physics keeps `Fadenstrahlrohr` deferred even after discovering adjacent Bayern raw-source evidence

What changed:

no new Niedersachsen Physics mapping row was added in this step:
curricula/DE/Gymnasium/mapping/DE-NI/upper-secondary/ni_physics_upper_secondary_to_canonical_physics.json remains at 55 reviewed rows
no new canonical Physics atom was introduced:
the shared canonical Physics graph still does not isolate a sufficiently narrow fine-beam-tube / specific-charge measurement target
the remaining Niedersachsen source-led residue stays:
0966258c-1eaa-4c41-8311-17352dcf0ec1 (Spezifische Ladung von Elektronen mit dem Fadenstrahlrohr einordnen)
the decision is now explicit because adjacent second-state evidence exists in the broader Bayern source file:
curricula/DE/Gymnasium/input/BY/gymnasium/Physik.json
4a5610d3-febc-5686-9996-ca232fceb44a combines Elektronenablenkroehre verification in the electric transverse field with electron-mass determination via Fadenstrahlrohr

Why no bridge yet:

the newly surfaced Bayern evidence is real, but it is not yet an imported retained reviewed second-state corridor on the active canonical Physics rollout path
the Niedersachsen wording stays narrower and differently framed (spezifische Ladung / principle / target quantity) than the broader Bayern experiment wording (Elektronenablenkroehre, regression, mass determination, uncertainty assessment)
authoring a new shared canonical measurement atom before a retained reviewed second-state lane exists would overtake the current source-led rollout discipline

Validation used:

python3 scripts/render_canonical_physics_bundesland_status.py
git diff --check

Interpretation:

Niedersachsen Physics is now explicitly closed at the current retained pilot-cut level
the remaining Fadenstrahlrohr clause is not forgotten debt, but a deliberately deferred shared-measurement candidate for a later multi-state retained rollout

2026-04-15: Niedersachsen Physics closes the deferred `Fadenstrahlrohr` residue via an imported Bayern second-state corridor

What changed:

one new shared canonical Physics atom was introduced:
966782e5-690d-4fae-bbab-fa3fa30525c3 (Fadenstrahlrohr als Elektronen-Messverfahren einordnen)
the repository-backed Niedersachsen Physics mapping lane:
curricula/DE/Gymnasium/mapping/DE-NI/upper-secondary/ni_physics_upper_secondary_to_canonical_physics.json now carries 56 reviewed rows instead of 55
one new reviewed Niedersachsen bridge was added:
0966258c-1eaa-4c41-8311-17352dcf0ec1 (Spezifische Ladung von Elektronen mit dem Fadenstrahlrohr einordnen) -> 966782e5-690d-4fae-bbab-fa3fa30525c3 (Fadenstrahlrohr als Elektronen-Messverfahren einordnen) (partial)
the retained Bayern second-state evidence is now imported on the active canonical path:
curricula/DE/Gymnasium/mapping/DE-BY/gymnasium/bavaria_physics_to_canonical_physics.json now carries 44 reviewed rows instead of 43
4a5610d3-febc-5686-9996-ca232fceb44a -> 966782e5-690d-4fae-bbab-fa3fa30525c3 (partial)
after applicability compilation, the new shared measurement atom now carries:
DE-BY, DE-NI
no new accepted-warning debt was needed for this step:
the widened shared measurement surface produces no new applicability findings on the new atom or its parent cluster

Why this cut now:

the earlier defer decision was correct at the time, because a single-state Niedersachsen clause alone would have forced a premature shared measurement atom
once the adjacent retained Bayern experiment corridor was actually imported and reviewed, the multi-state evidence became concrete enough to justify a narrow shared canonical leaf
the new atom is still intentionally narrower than the broader Bayern experimental clause and broader than the Niedersachsen wording, so both state bridges stay defensibly partial

python3 scripts/render_canonical_physics_bundesland_status.py

Interpretation:

Niedersachsen Physics no longer has a measurement-specific source-led residue on the active retained pilot surface
the only intentionally source-led Niedersachsen Physics residue is now the sustainability-related Bewertungsblatt from the E-phase energy strip

2026-04-15: Berlin upper-secondary Physics opens the first reviewed Q1 field/capacitor corridor

What changed:

the first retained Berlin upper-secondary Physics source PDF is now archived locally:
curricula/DE/Gymnasium/input/BE/upper-secondary/Teil_C_RLP_GOST_2022_Physik.pdf
the first Berlin upper-secondary Physics source snapshot is now active:
curricula/DE/Gymnasium/input/BE/upper-secondary/source-json/DE_BER_S_GYM_2_PHYSIK.de.json.snapshot
the retained source lane is now registered in the shared DE-level source registry:
8e54a9e6-dd9d-4f5d-a632-734b4ef5c754 (Physik Oberstufe (Berlin, Pilot-Quellsnapshot))
provenance-backed membership and atomic closure are now active for that retained snapshot:
source-goal-membership-registry.json
source-goal-closure-registry.json
the first repository-backed Berlin upper-secondary Physics mapping lane now exists:
curricula/DE/Gymnasium/mapping/DE-BE/upper-secondary/be_physics_upper_secondary_to_canonical_physics.json
10 reviewed rows
the first reviewed Berlin corridor is intentionally narrow:
one shared orientation anchor
one structural Q1 field anchor
one first reviewed Q1 electric-field / capacitor corridor
no canonical Physics atom was added in this step:
the Berlin start reuses the existing shared Q1 field/capacitor surface
no committed Berlin applicability cut was added in this step:
Berlin stays a reviewed P4 source/mapping lane without a DE-BE applicability persist pass

Why this cut:

Berlin is the cleanest next real Physics rollout lane after the closed Niedersachsen maintenance pass because the retained BE/BB upper-secondary PDF offers a narrow 3.2.1 field corridor that already fits the shared canonical Q1 field/capacitor surface
the start stays intentionally conservative:
no Berlin-only canonical atom
no Berlin-specific composition view
no premature applicability cut
this keeps the next move obvious:
extend the same retained Berlin 3.2.1 route toward magnetic field or charged-particle motion before opening another new state

Interpretation:

canonical Physics now has a real fifth active non-Hessen/Bayern maintenance-era source lane beyond the already active NRW/BW/NI surface
Berlin is active as a narrow reviewed P4 entry lane, but still intentionally does not widen learner-facing applicability or composition-view debt yet

2026-04-15: Berlin upper-secondary Physics widens the retained `3.2.1` route onto the shared magnetic-field surface

What changed:

the active Berlin upper-secondary Physics source snapshot
curricula/DE/Gymnasium/input/BE/upper-secondary/source-json/DE_BER_S_GYM_2_PHYSIK.de.json.snapshot now includes one first retained 3.2.1 magnetic-field / Lorentz-force follow-on next to the earlier electric-field / capacitor corridor
the Berlin snapshot contributes five additional retained source goals through the shared provenance registries:
one corridor parent Q1: Magnetfeld und Lorentzkraft (erster Follow-on-Korridor)
four leaves on field line diagrams, magnetic flux density via conductor force, long-coil field strength, and Lorentz force
the repository-backed Berlin Physics mapping lane
curricula/DE/Gymnasium/mapping/DE-BE/upper-secondary/be_physics_upper_secondary_to_canonical_physics.json now carries 15 reviewed rows instead of 10
the new reviewed Berlin bridges are:
retained corridor parent -> shared canonical cluster Magnetisches Feld (partial)
Feldlinienbilder von Permanentmagneten, geradem Leiter und Spule beschreiben -> Magnetische Felder und Feldlinienbilder (exact)
Magnetische Flussdichte ueber Leiterkraft deuten -> Kraft auf stromdurchflossene Leiter (partial)
Magnetische Flussdichte in der langen Spule und Materialeinfluss beschreiben -> Magnetfeld von geradem Leiter und Spule (partial)
Lorentzkraft auf bewegte Ladungen im Magnetfeld beschreiben -> Lorentzkraft auf freie Ladungen (partial)
no canonical Physics atom was added in this step:
the Berlin follow-on reuses the existing shared Q1 magnetic-field surface
no committed Berlin applicability cut was added in this step

Why this cut:

continuing Berlin on the same retained 3.2.1 route is cleaner than jumping immediately into 3.2.2, because the shared canonical Q1 magnetic-field surface already exists and matches the source wording well enough for conservative reviewed bridges
the exact/partial split stays disciplined:
field-line diagrams are one-to-one enough for exact
conductor force, long-coil field strength, and Lorentz force stay partial because the retained Berlin wording is still narrower than the broader shared canonical leaves
this leaves the next move obvious:
extend Berlin into 3.2.2 Bewegung von geladenen Teilchen in Feldern

python3 scripts/render_canonical_physics_bundesland_status.py

Interpretation:

Berlin no longer stops at the electric-field / capacitor entry and now covers the first retained magnetic-field follow-on on the same Q1 route
the lane still remains a narrow reviewed P4 source/mapping slice with no Berlin-specific applicability or composition-view debt

2026-04-15: Berlin upper-secondary Physics extends the retained Q1 route into `3.2.2 Bewegung von geladenen Teilchen in Feldern`

What changed:

the active Berlin upper-secondary Physics source snapshot
curricula/DE/Gymnasium/input/BE/upper-secondary/source-json/DE_BER_S_GYM_2_PHYSIK.de.json.snapshot now also includes one retained 3.2.2 follow-on corridor with:
one electric subcluster on longitudinal field, transverse field, and Millikan
one intentionally source-led c0 clause
one magnetic subcluster on circle motion in homogeneous magnetic fields and the specific charge of the electron
the shared provenance registries now carry nine additional retained Berlin source goals on that route:
one corridor parent
two retained subclusters
six retained leaves
the repository-backed Berlin Physics mapping lane
curricula/DE/Gymnasium/mapping/DE-BE/upper-secondary/be_physics_upper_secondary_to_canonical_physics.json now carries 21 reviewed rows instead of 15
the new reviewed Berlin bridges are:
retained electric 3.2.2 subcluster -> Ladungen in Feldern (partial)
longitudinal-field leaf -> Geladene Teilchen in homogenen elektrischen Feldern untersuchen (partial)
transverse-field leaf -> Geladene Teilchen in homogenen elektrischen Feldern untersuchen (partial)
Millikan-Experiment im Schwebefall einordnen -> Millikan-Versuch und Elementarladung (partial)
circle-motion leaf -> Geladene Teilchen in homogenen magnetischen Feldern untersuchen (partial)
Spezifische Ladung des Elektrons bestimmen -> Fadenstrahlrohr als Elektronen-Messverfahren einordnen (partial)
no canonical Physics atom was added in this step
no committed Berlin applicability cut was added in this step
Vakuumlichtgeschwindigkeit c0 als Obergrenze fuer Geschwindigkeiten einordnen intentionally stays source-led

Why this cut:

continuing Berlin on the same retained Q1 field route is still cleaner than opening a new state, because the shared canonical Physics graph already exposes narrow enough reviewed targets for the electric-field, Millikan, magnetic-field, and Fadenstrahlrohr parts of 3.2.2
the cut stays disciplined:
no Berlin-only canonical atom
no Berlin-specific composition view
no premature applicability pass
no forced canonical target for the c0 clause
this leaves the next move narrow again:
make the remaining c0 / LK-only residue explicit before opening another new Physics state

Interpretation:

Berlin now covers the retained Q1 field route through 3.2.1 and into the first shared part of 3.2.2
the lane still remains a narrow reviewed P4 source/mapping slice with no Berlin-specific applicability or composition-view debt

2026-04-15: Berlin upper-secondary Physics makes the first LK residue on the retained `3.2.2` route explicit

What changed:

the active Berlin upper-secondary Physics source snapshot
curricula/DE/Gymnasium/input/BE/upper-secondary/source-json/DE_BER_S_GYM_2_PHYSIK.de.json.snapshot now includes one explicit retained LK residue subcluster on:
mathematical electric-field trajectories
relativistic mass increase
arbitrary entry angles in magnetic fields
crossed electric/magnetic fields
Hall-Effekt / Hall-Spannung
Elektronenstrahlroehre as a specific-charge measurement context
the shared provenance registries now carry seven additional retained Berlin source goals on that route:
one LK residue parent
six LK leaves
the repository-backed Berlin Physics mapping lane
curricula/DE/Gymnasium/mapping/DE-BE/upper-secondary/be_physics_upper_secondary_to_canonical_physics.json now carries 24 reviewed rows instead of 21
the new reviewed Berlin bridges are:
Geladene Teilchen in gekreuzten elektrischen und magnetischen Feldern beschreiben -> Geladene Teilchen in homogenen elektrischen Feldern untersuchen (partial)
Hall-Effekt und Hall-Spannung anwenden -> Hall-Effekt anwenden (partial)
Elektronenstrahlroehre zur Bestimmung der spezifischen Ladung einordnen -> Fadenstrahlrohr als Elektronen-Messverfahren einordnen (partial)
no canonical Physics atom was added in this step
no committed Berlin applicability cut was added in this step
the remaining Berlin residues
Vakuumlichtgeschwindigkeit c0 als Obergrenze fuer Geschwindigkeiten einordnen
Relativistische Massenzunahme schnell bewegter Teilchen einordnen
Ladungstraeger in Magnetfeldern fuer beliebige Eintrittswinkel beschreiben intentionally stay source-led

Why this cut:

the clean move here was to make the retained LK residue explicit without pretending that all of it already has narrow shared canonical coverage
three parts already overlap enough with reviewed shared targets:
crossed-field motion with the existing electric-field particle-motion target
Hall-Effekt with the existing LK Hall-Effekt anwenden leaf
Elektronenstrahlroehre as a specific-charge measurement context with the shared Fadenstrahlrohr measurement leaf
the remaining three clauses still do not justify another canonical split or a Berlin-specific atom

Interpretation:

Berlin now covers the retained Q1 field route through 3.2.1, the shared part of 3.2.2, and the first narrow LK continuation on that same route
the only remaining Berlin source-led debt on this lane is now the explicit trio c0 / Relativitaet / Eintrittswinkel

2026-04-15: Berlin upper-secondary Physics keeps the remaining `c0` / `Relativitaet` / `Eintrittswinkel` trio source-led after explicit target review

What changed:

the Berlin Physics lane itself stays unchanged at:
24 reviewed mappings
no Berlin-specific canonical Physics atom
no Berlin-specific composition view
no committed Berlin applicability cut
the remaining source-led Berlin trio is now explicitly documented as a deferred shared BE/BB residue candidate:
86b6e00c-3015-4da4-82f4-4d7c4a0a9cc0 (Vakuumlichtgeschwindigkeit c0 als Obergrenze fuer Geschwindigkeiten einordnen)
a7c898a2-1911-4913-b4c9-6ab2aab75db9 (Relativistische Massenzunahme schnell bewegter Teilchen einordnen)
7dc4ed91-6ecb-4c54-a883-cb681fab9bdb (Ladungstraeger in Magnetfeldern fuer beliebige Eintrittswinkel beschreiben)
onboarding, the Berlin mapping-lane README, the Physics rollout tracker, the quick view, the topic workboard, and the M2 shortlist now all describe that trio as intentionally deferred instead of as an open Berlin-only mapping todo

Why this decision:

the current shared canonical Physics graph still has no reviewed narrow leaf for the c0 clause without overclaiming into broader relativity packaging
the existing shared relativistic-mass leaf is still too Hessen-specific in its linear-accelerator framing for the Berlin wording
the existing shared magnetic particle-motion leaves still do not isolate the arbitrary-entry-angle clause tightly enough to justify another reviewed bridge
forcing another Berlin-only canonical split here would weaken the current source-led multi-state discipline instead of improving it

Validation used:

python3 scripts/render_canonical_physics_bundesland_status.py
git diff --check

Interpretation:

the retained Berlin Q1 field route is now operationally closed at the current reviewed level
the next clean Physics move is no longer another Berlin widening, but a second-state follow-on from the shared BE/BB upper-secondary source family if that deferred trio later becomes jointly reviewable

2026-04-15: Brandenburg upper-secondary Physics opens the second state on the shared BE/BB upper-secondary source family

What changed:

the first Brandenburg upper-secondary Physics source PDF is now archived locally at:
curricula/DE/Gymnasium/input/BB/upper-secondary/Teil_C_RLP_GOST_2022_Physik.pdf
the first Brandenburg upper-secondary Physics source snapshot is now active:
curricula/DE/Gymnasium/input/BB/upper-secondary/source-json/DE_BRA_S_GYM_2_PHYSIK.de.json.snapshot
the retained source lane is now registered in the shared DE-level source registry:
6759f46a-5642-41f7-8dc7-71fd1c335855 (Physik Oberstufe (Brandenburg, Pilot-Quellsnapshot))
provenance-backed membership and atomic closure are now active for that retained snapshot:
source-goal-membership-registry.json
source-goal-closure-registry.json
the first repository-backed Brandenburg upper-secondary Physics mapping lane now exists:
curricula/DE/Gymnasium/mapping/DE-BB/upper-secondary/bb_physics_upper_secondary_to_canonical_physics.json
10 reviewed rows
the first reviewed Brandenburg corridor is intentionally narrow:
one shared orientation anchor
one structural Q1 field anchor
one first reviewed Q1 electric-field / capacitor corridor
no canonical Physics atom was added in this step:
the Brandenburg start reuses the existing shared Q1 field/capacitor surface
no committed Brandenburg applicability cut was added in this step:
Brandenburg starts as a reviewed P4 source/mapping lane without a DE-BB applicability persist pass

Why this cut:

after Berlin closed its current retained 3.2.1 -> 3.2.2 Q1 route at the reviewed level, the clean next move was to open the second state from the same BE/BB upper-secondary source family instead of forcing another Berlin-only canonical split
starting Brandenburg on the already stable shared Q1 field/capacitor surface keeps the multi-state comparison honest while staying narrow:
no Brandenburg-only canonical atom
no Brandenburg-specific composition view
no premature applicability cut
this leaves the next move narrow and obvious again:
widen Brandenburg on the retained 3.2.1 route toward magnetic field / Lorentzkraft before reopening the shared BE/BB residue on c0, Relativitaet, and Eintrittswinkel

canonical Physics now has a real seventh active non-maintenance state lane on the current reviewed path
the Berlin/Brandenburg upper-secondary source family is now open on both state lanes, but still intentionally only at the narrow reviewed Q1 field/capacitor entry level for Brandenburg

2026-04-15: Brandenburg upper-secondary Physics widens the retained `3.2.1` route onto the shared magnetic-field surface

What changed:

the active Brandenburg upper-secondary Physics snapshot now also carries one first reviewed retained 3.2.1 magnetic-field / Lorentz-force follow-on:
parent cluster Q1: Magnetfeld und Lorentzkraft (erster Follow-on-Korridor)
four reviewed leaves on field-line diagrams, conductor-force interpretation, long-coil field strength, and Lorentz force
the Brandenburg source snapshot now contributes 15 reviewed source goals via source-goal-membership-registry.json
the same snapshot now contributes widened atomic closures via source-goal-closure-registry.json
the repository-backed Brandenburg upper-secondary Physics mapping lane now carries 15 reviewed rows:
one partial bridge from the new Brandenburg magnetic parent onto the shared canonical Magnetisches Feld cluster
one exact bridge from the Brandenburg field-line leaf onto the canonical atom of the same pedagogical surface
three conservative partial bridges onto Kraft auf stromdurchflossene Leiter, Magnetfeld von geradem Leiter und Spule, and Lorentzkraft auf freie Ladungen
no canonical Physics atom was added in this step:
the Brandenburg follow-on reuses the existing shared magnetic-field surface that was already stable from Hessen, Niedersachsen, Nordrhein-Westfalen, Baden-Wuerttemberg, and Berlin
no committed Brandenburg applicability cut was added in this step:
Brandenburg remains a reviewed P4 source/mapping lane without a DE-BB applicability persist pass

Why this cut:

after the first Brandenburg Q1 electric-field / capacitor entry, the clean next move was to widen the same retained 3.2.1 route before opening another source family or forcing the deferred shared BE/BB residue
the shared canonical magnetic-field strip was already narrow enough to absorb this second-state follow-on without inventing another visible package:
no Brandenburg-only canonical atom
no Brandenburg-specific composition view
no premature applicability cut
this keeps the next move narrow and obvious again:
widen Brandenburg next into retained 3.2.2 Bewegung geladener Teilchen in Feldern before reopening c0, Relativitaet, and Eintrittswinkel

git diff --check

Interpretation:

the shared BE/BB upper-secondary source family is now open on both state lanes across the retained 3.2.1 electric and magnetic strip
the next clean Physics move inside that family is no longer another Brandenburg 3.2.1 widening, but the retained 3.2.2 charged-particle-motion follow-on

2026-04-15: Brandenburg upper-secondary Physics closes the retained `3.2.2` route at the current reviewed level

What changed:

the active Brandenburg upper-secondary Physics snapshot now also carries one first reviewed retained 3.2.2 charged-particle-motion follow-on:
one electric-field subsurface on longitudinal acceleration, transverse trajectories, and the Millikan experiment
one magnetic-field subsurface on circular trajectories and specific charge
one explicit LK side-lane on crossed fields, Hall-Effekt, and Elektronenstrahlroehre
the c0 leaf and the LK leaves on relativistic mass increase plus arbitrary entry angles stay explicitly source-led
the Brandenburg source snapshot now contributes 31 reviewed source goals via source-goal-membership-registry.json
the same snapshot now contributes widened atomic closures with 24 root atomics via source-goal-closure-registry.json
the repository-backed Brandenburg upper-secondary Physics mapping lane now carries 24 reviewed rows:
new partial bridges on the shared charged-particle-motion surfaces in electric and magnetic fields
new partial bridge on Millikan-Versuch und Elementarladung
new partial bridges on the shared measurement surface for specific charge / Elektronenstrahlroehre
new partial bridges on crossed fields and Hall-Effekt where narrow shared targets already existed
no canonical Physics atom was added in this step:
the Brandenburg follow-on still reuses the existing shared Q1 field / particle-motion surface
no committed Brandenburg applicability cut was added in this step:
Brandenburg remains a reviewed P4 source/mapping lane without a DE-BB applicability persist pass

Why this cut:

after the reviewed Brandenburg retained 3.2.1 electric and magnetic strip, the clean next move was to close the matching retained 3.2.2 corridor from the same BE/BB source family instead of forcing another canonical split
the shared canonical particle-motion surface was already narrow enough to absorb this second-state follow-on without inventing another visible package:
no Brandenburg-only canonical atom
no Brandenburg-specific composition view
no premature applicability cut
this leaves the remaining BE/BB debt explicit and honest:
c0
Relativitaet
Eintrittswinkel

python3 scripts/render_canonical_physics_bundesland_status.py
cd backend && GRADLE_USER_HOME=/home/enpasos/projects/skillpilot/backend/.gradle-ci ./gradlew clean check --no-daemon
git diff --check

Interpretation:

Brandenburg now matches the current reviewed Berlin cut on the retained 3.2.1 -> 3.2.2 route
the shared BE/BB upper-secondary source family is therefore operationally closed at the current reviewed level
the next clean Physics move is no longer another Brandenburg widening, but either an explicit shared BE/BB residue decision or a different state/source family

2026-04-15: Berlin/Brandenburg upper-secondary Physics freezes the shared `c0` / `Relativitaet` / `Eintrittswinkel` residue at the current reviewed level

What changed:

no Berlin or Brandenburg mapping rows changed in this step:
DE-BE stays at 24 reviewed mappings
DE-BB stays at 24 reviewed mappings
no canonical Physics atom was added in this step
no applicability cut was added in this step
onboarding notes, mapping-lane READMEs, the rollout tracker, the quick-view, the topic workboard, and the M2 shortlist now all treat the remaining trio as an explicitly frozen shared BE/BB residue set instead of as an immediately pending next bridge

Why this decision:

the Berlin-only target review already showed that the current shared canonical Physics graph still has no reviewed narrow leaf for the c0 clause without overclaiming into broader relativity packaging
after Brandenburg now matches the same retained 3.2.1 -> 3.2.2 cut, the shared evidence still does not improve that conclusion:
the existing shared relativistic-mass leaf remains too Hessen-shaped in its linear-accelerator framing
the existing shared magnetic-field particle-motion leaves still do not isolate the arbitrary-entry-angle clause tightly enough
forcing another BE/BB-only canonical split here would widen ontology debt without creating a stable shared surface

Validation used:

python3 scripts/render_canonical_physics_bundesland_status.py
git diff --check

Interpretation:

the shared BE/BB upper-secondary family is now not only operationally closed at the current reviewed cut, but also explicitly closed against another immediate residue bridge
the next clean Physics rollout move should therefore come from a different state/source family unless later reviewed evidence genuinely changes that residue assessment

2026-04-16: Schleswig-Holstein upper-secondary Physics opens a first retained field-concept corridor

What changed:

Schleswig-Holstein now has an active upper-secondary Physics source snapshot:
curricula/DE/Gymnasium/input/SH/upper-secondary/source-json/DE_SHL_S_GYM_2_PHYSIK.de.json.snapshot
the new SH upper-secondary Physics lane is now active in:
source-landscape-registry.json
source-goal-membership-registry.json
source-goal-closure-registry.json
the repository-backed SH mapping lane now exists:
curricula/DE/Gymnasium/mapping/DE-SH/upper-secondary/sh_physics_upper_secondary_to_canonical_physics.json
the lane currently carries 10 reviewed mappings:
one partial bridge from the SH source root onto the canonical Physics root
one exact bridge on the shared orientation anchor
one partial bridge from the structural SH field anchor onto Q1 Elektrisches und magnetisches Feld
one partial bridge from the retained SH corridor parent onto the shared canonical cluster Elektrisches Feld
six conservative partial leaf bridges on the field-concept surface for charge phenomena, Coulomb interaction, field-line sketches, and superposition
no canonical Physics atom was added in this step
no committed Schleswig-Holstein applicability cut was added in this step

Why this cut:

after the shared BE/BB residue was explicitly frozen, the clean next move was to open a different retained source family instead of forcing another weak bridge on c0 / Relativitaet / Eintrittswinkel
Schleswig-Holstein is a good next source because the combined-stage Fachanforderungen expose a clear Sek-II topic row Elektrische und magnetische Felder that already sits close to the current shared Q1 field surface
the first SH cut therefore stays narrow and source-led:
one shared orientation anchor
one structural upper-secondary field anchor
one first reviewed corridor on Das Feldkonzept zur Beschreibung von Wechselwirkungen

python3 scripts/render_canonical_physics_bundesland_status.py
cd backend && GRADLE_USER_HOME=/home/enpasos/projects/skillpilot/backend/.gradle-ci ./gradlew clean check --no-daemon
git diff --check

Interpretation:

Physics now has a real eighth active Bundesland lane on the current canonical path
the active follow-on is no longer another new source family immediately, but the next retained SH step on Koerper in statischen Feldern

2026-04-16: Schleswig-Holstein upper-secondary Physics widens onto a first static-fields follow-on

What changed:

the active Schleswig-Holstein upper-secondary Physics source snapshot
curricula/DE/Gymnasium/input/SH/upper-secondary/source-json/DE_SHL_S_GYM_2_PHYSIK.de.json.snapshot now widens the retained source family Elektrische und magnetische Felder beyond the first field-concept cut
the same SH source lane now carries one first reviewed follow-on on the official subtopic Koerper in statischen Feldern
the repository-backed SH mapping lane
curricula/DE/Gymnasium/mapping/DE-SH/upper-secondary/sh_physics_upper_secondary_to_canonical_physics.json now carries 15 reviewed mappings
the widened SH leaves resolve conservatively onto existing shared canonical atoms for:
charges in electric fields
Lorentzkraft
motion in homogeneous electric and magnetic fields
work/energy in electric fields
no canonical Physics atom was added in this step
no committed Schleswig-Holstein applicability cut was added in this step

Why this cut:

after the first SH field-concept corridor, the clean next move was to stay on the same official source family instead of opening another state/source family immediately
Koerper in statischen Feldern is the adjacent retained SH subtopic on the same row and already fits existing shared Q1 field atoms without forcing a new canonical package
the current SH cut therefore stays narrow and source-led:
one first follow-on for electric force, Lorentzkraft, homogeneous field motion, and acceleration energy
the residue on Kreisbewegungen, Elektronenmessung, and technischen Anwendungen remains intentionally open for the next SH move

python3 scripts/render_canonical_physics_bundesland_status.py
cd backend && GRADLE_USER_HOME=/home/enpasos/projects/skillpilot/backend/.gradle-ci ./gradlew clean check --no-daemon

Interpretation:

Schleswig-Holstein now has a widened reviewed Physics lane on the current canonical path, not just a first-entry seed
the active follow-on remains inside the same SH source family, specifically on the remaining Koerper in statischen Feldern residue

2026-04-16: Schleswig-Holstein upper-secondary Physics widens onto Elektronenmessung und technische Anwendungen

What changed:

the active Schleswig-Holstein upper-secondary Physics source snapshot
curricula/DE/Gymnasium/input/SH/upper-secondary/source-json/DE_SHL_S_GYM_2_PHYSIK.de.json.snapshot now widens the retained source family Elektrische und magnetische Felder by a second follow-on inside Koerper in statischen Feldern
the repository-backed SH mapping lane
curricula/DE/Gymnasium/mapping/DE-SH/upper-secondary/sh_physics_upper_secondary_to_canonical_physics.json now carries 19 reviewed mappings
the widened SH leaves resolve conservatively onto existing shared canonical atoms for:
Millikan-Versuch und Elementarladung
Fadenstrahlrohr als Elektronen-Messverfahren einordnen
Hall-Effekt anwenden
Teilchenbeschleuniger (Zyklotron/Synchrotron)
the adjacent SH Massenspektrometer leaf is now explicit in the source snapshot and remains intentionally source-led because the current shared canonical Physics surface still has no narrow reviewed target for it
no canonical Physics atom was added in this step
no committed Schleswig-Holstein applicability cut was added in this step

Why this cut:

after the first SH field-concept corridor and the first static-fields follow-on, the clean next move was to stay on the same official SH source family instead of switching topic rows or forcing a new canonical package
the official SH clause on Elektronenmessung und technischen Anwendungen already overlaps with existing shared measurement/application atoms for Millikan, Fadenstrahlrohr, Hall-Effekt, and Teilchenbeschleuniger
Massenspektrometer still lacks that narrow shared target, so the second SH follow-on stays conservative and explicitly leaves that one application source-led

python3 scripts/render_canonical_physics_bundesland_status.py
cd backend && GRADLE_USER_HOME=/home/enpasos/projects/skillpilot/backend/.gradle-ci ./gradlew clean check --no-daemon
git diff --check

Interpretation:

Schleswig-Holstein now has a materially widened reviewed Physics lane on the current canonical path, not just one first-entry corridor plus one adjacent follow-on
the remaining open SH residue on this source family is now mainly Kreisbewegungen, while Massenspektrometer is an explicit source-led micro-residue rather than an implicit missing slice

2026-04-16: Schleswig-Holstein upper-secondary Physics widens onto Kreisbewegungen

What changed:

the active Schleswig-Holstein upper-secondary Physics source snapshot
curricula/DE/Gymnasium/input/SH/upper-secondary/source-json/DE_SHL_S_GYM_2_PHYSIK.de.json.snapshot now widens the retained source family Elektrische und magnetische Felder by a third follow-on inside Koerper in statischen Feldern
the repository-backed SH mapping lane
curricula/DE/Gymnasium/mapping/DE-SH/upper-secondary/sh_physics_upper_secondary_to_canonical_physics.json now carries 22 reviewed mappings
the widened SH leaves resolve conservatively onto existing shared canonical atoms for:
Bahn- und Winkelgeschwindigkeit
Zentripetalkraft herleiten
Kreisbewegung mit Zentripetalkraft anwenden
the adjacent SH leaf Drehimpuls und Drehimpulserhaltung is now explicit in the source snapshot and remains intentionally source-led because the current shared canonical Physics surface on that concept is still a separate Drehbewegungsflaeche rather than a narrow continuation of the SH static-fields clause
no canonical Physics atom was added in this step
no committed Schleswig-Holstein applicability cut was added in this step

Why this cut:

after the first SH field-concept corridor and the two adjacent static-fields/application follow-ons, the clean next move was to finish the circle-motion strip on the same official SH source family instead of switching rows too early
the official SH wording on Kreisbewegungen already overlaps with the existing shared mechanics surface for orbital/angular velocity, centripetal force, and quantitative circular-motion analysis
Drehimpuls und Drehimpulserhaltung still sits on a broader rotational-mechanics surface, so the third SH follow-on stays conservative and explicitly leaves that one concept source-led

python3 scripts/render_canonical_physics_bundesland_status.py
cd backend && GRADLE_USER_HOME=/home/enpasos/projects/skillpilot/backend/.gradle-ci ./gradlew clean check --no-daemon

Interpretation:

Schleswig-Holstein now has a broadly widened reviewed Physics lane on the current canonical path across the opened SH field source family
the remaining open SH debt on this family is no longer a hidden missing corridor but two explicit source-led micro-residues: Massenspektrometer and Drehimpuls und Drehimpulserhaltung

2026-04-16: Schleswig-Holstein upper-secondary Physics freezes its two remaining micro-residues

What changed:

the Schleswig-Holstein upper-secondary Physics lane is now treated as complete at the current reviewed pilot-cut level
the two remaining SH source leaves
Massenspektrometer
Drehimpuls und Drehimpulserhaltung are now explicitly frozen as source-led micro-residues in the SH onboarding, lane README, rollout tracker, workboard, shortlist, and quick-view artifacts
no mappings changed in this step
no canonical Physics atom was added in this step
no committed Schleswig-Holstein applicability cut was added in this step

Why this cut:

after the first field-concept corridor and the three adjacent SH follow-ons, the active SH source family no longer has a didactically meaningful reviewed widening left without forcing weak or semantically stretched bridges
Massenspektrometer still has no narrow shared canonical target on the current field strip
Drehimpuls und Drehimpulserhaltung still belongs to a broader rotational-mechanics surface rather than to a narrow continuation of the retained SH static-fields clause

Validation used:

python3 scripts/render_canonical_physics_bundesland_status.py
git diff --check

Interpretation:

Schleswig-Holstein is now operationally in the same maintenance-style state as the other reviewed retained upper-secondary lanes
the next clean Physics rollout move should therefore come from a new state/source family rather than from another SH residue attempt

2026-04-16: Rheinland-Pfalz Physics is now the explicit next source-onboarding target

What changed:

Rheinland-Pfalz Physics is now explicitly tracked as the next active source-onboarding target in:
curricula/DE/Gymnasium/provenance/physics-bundesland-rollout-tracker.json
docs/dev/canonical-gymnasium-physics-topic-workboard.md
docs/dev/canonical-gymnasium-physics-m2-lane-shortlist.md
docs/dev/canonical-gymnasium-physics-parity-plan.md
a dedicated onboarding note now exists at:
curricula/DE/Gymnasium/provenance/rp-physics-onboarding.md
the Rheinland-Pfalz input README now records the current official MSS Physics source route at:
curricula/DE/Gymnasium/input/RP/README.md
the current official Sek-II source is identified as the Schulcampus node:
25a2f512-91be-4a59-9dc5-342aece95a0b
title Lehrplan Physik - Grund- und Leistungsfach
file Physik_SekII.pdf
Rheinland-Pfalz intentionally remains at P0
no RP Physics snapshot, registry activation, mapping lane, canonical atom, or applicability cut was added in this step

Why this cut:

after Schleswig-Holstein was explicitly closed at the current reviewed pilot cut, the next clean Physics move had to open a new source family rather than widening more frozen residues
Rheinland-Pfalz is the nearest attractive next state because the official MSS Physics source is already identifiable from the public Bildungsserver / Schulcampus route and the repository already has a mature RP mathematics lane
the actual current Physics PDF is not yet archived locally, and the public download route currently redirects anonymous requests through Schulcampus session validation
authoring a reviewed RP lane from metadata-only evidence would therefore be weaker than stopping explicitly at source-onboarding

Validation used:

python3 scripts/render_canonical_physics_bundesland_status.py
git diff --check

Interpretation:

Physics now has an explicit next active source-onboarding target again instead of an empty immediate queue
the next correct RP move is source acquisition and archival, not a fabricated snapshot or mapping corridor

2026-04-16: Rheinland-Pfalz Physics lane is now active on the first reviewed GF/LF-common field-concept strip

What changed:

the current official Rheinland-Pfalz MSS Physics PDF is now archived locally at:
curricula/DE/Gymnasium/input/RP/Physik_Sekundarstufe_II_MSS.pdf
the first RP upper-secondary Physics source snapshot now exists at:
curricula/DE/Gymnasium/input/RP/upper-secondary/source-json/DE_RLP_S_GYM_2_PHYSIK.de.json.snapshot
the first RP mapping lane now exists at:
curricula/DE/Gymnasium/mapping/DE-RP/upper-secondary/rp_physics_upper_secondary_to_canonical_physics.json
the RP Physics lane is now active in:
curricula/DE/Gymnasium/provenance/source-landscape-registry.json
curricula/DE/Gymnasium/provenance/source-goal-membership-registry.json
curricula/DE/Gymnasium/provenance/source-goal-closure-registry.json
the repository-backed fixture now covers the new lane in:
backend/src/test/java/com/skillpilot/backend/landscape/GoalMappingRepositoryFixtureTest.java

Current reviewed RP cut:

11 reviewed mappings
one shared orientation anchor
one structural Qualifikationsphasen-Anker Statische elektrische und magnetische Felder
one first reviewed gemeinsamer Grundfach-/Leistungsfach-Korridor on the Pflichtbaustein Feldkonzept fuer statische elektrische und magnetische Felder
no Rheinland-Pfalz-specific canonical Physics atom
no committed Rheinland-Pfalz applicability cut

Why this cut:

the actual official source is now locally archived and inspectable, so the lane no longer has to stop at metadata-backed P0
the first corridor is intentionally limited to the narrow GF/LF overlap on the static field-concept strip
the adjacent Energie-/Speicherstreifen is not widened yet because the GF/LF overlap there is less clean and would otherwise overclaim the current shared canonical surface

Interpretation:

Physics now has a real ninth state lane on the canonical DE path, not just another placeholder
the next clean Physics move stays inside Rheinland-Pfalz on the adjacent GF/LF-common static-field interaction strip

2026-04-16: Rheinland-Pfalz Physics now also carries the first reviewed GF/LF-common static-field interaction follow-on

What changed:

the active RP upper-secondary Physics snapshot in
curricula/DE/Gymnasium/input/RP/upper-secondary/source-json/DE_RLP_S_GYM_2_PHYSIK.de.json.snapshot now includes one adjacent reviewed GF/LF-common follow-on on Wechselwirkung von geladenen Koerpern mit statischen Feldern
the RP mapping lane in
curricula/DE/Gymnasium/mapping/DE-RP/upper-secondary/rp_physics_upper_secondary_to_canonical_physics.json now carries the additional conservative bridges onto the shared canonical cluster Ladungen in Feldern plus the existing shared Q1 atoms for electric-field particle motion, work/energy in electric fields, Lorentzkraft, and magnetic-field particle motion
the provenance registries, rollout tracker, RP onboarding note, RP input README, lane README, topic workboard, parity plan, and lane shortlist are all updated accordingly
the repository-backed fixture in
backend/src/test/java/com/skillpilot/backend/landscape/GoalMappingRepositoryFixtureTest.java now covers 17 reviewed RP mappings

Current reviewed RP cut:

17 reviewed mappings
one shared orientation anchor
one structural Qualifikationsphasen-Anker Statische elektrische und magnetische Felder
one first reviewed gemeinsamer Grundfach-/Leistungsfach-Korridor on Feldkonzept fuer statische elektrische und magnetische Felder
one first reviewed GF/LF-common follow-on on Wechselwirkung von geladenen Koerpern mit statischen Feldern
no Rheinland-Pfalz-specific canonical Physics atom
no committed Rheinland-Pfalz applicability cut

Why this cut:

the GF/LF overlap on the RP static-field interaction strip is clean on five source leaves and does not require a new canonical package
the adjacent LF-only residue Hall-Effekt, Kreisbahnen geladener Teilchen im homogenen Magnetfeld, and Wien-Filter is narrower and should not be smuggled into the common RP cut
this keeps RP aligned with the established topic-first rollout rule: widen the shared reviewed strip first, leave the narrower LK-only tail explicit

python3 scripts/render_canonical_physics_bundesland_status.py
cd backend && GRADLE_USER_HOME=/home/enpasos/projects/skillpilot/backend/.gradle-ci ./gradlew clean check --no-daemon

Interpretation:

Rheinland-Pfalz stays the active Physics lane, but it is now past the entry cut and onto a second reviewed corridor on the same source family
the next clean Physics decision is no longer whether RP has a real second corridor, but whether the remaining LF-only residue now warrants a reviewed shared follow-on or should stay source-led while another GF/LF-common RP strip opens first

2026-04-16: Rheinland-Pfalz Physics now also carries the first narrow LK Hall follow-on

What changed:

the active RP upper-secondary Physics snapshot in
curricula/DE/Gymnasium/input/RP/upper-secondary/source-json/DE_RLP_S_GYM_2_PHYSIK.de.json.snapshot now exposes an explicit LK residue cluster for the same static-field interaction strip with three leaves:
Hall-Effekt
Kreisbahnen geladener Teilchen im homogenen Magnetfeld
Wien-Filter
the RP mapping lane in
curricula/DE/Gymnasium/mapping/DE-RP/upper-secondary/rp_physics_upper_secondary_to_canonical_physics.json now adds one new conservative mapping:
rp-phys-sek2-hall-effect -> Hall-Effekt anwenden (partial)
the remaining RP LK leaves Kreisbahnen and Wien-Filter stay intentionally source-led

Current reviewed RP cut:

18 reviewed mappings
one shared orientation anchor
one structural Qualifikationsphasen-Anker Statische elektrische und magnetische Felder
one first reviewed gemeinsamer Grundfach-/Leistungsfach-Korridor on Feldkonzept fuer statische elektrische und magnetische Felder
one first reviewed GF/LF-common follow-on on Wechselwirkung von geladenen Koerpern mit statischen Feldern
one first narrow reviewed LK follow-on on Hall-Effekt
no Rheinland-Pfalz-specific canonical Physics atom
no committed Rheinland-Pfalz applicability cut

Why this cut:

Hall-Effekt is the cleanest narrow RP-LK continuation because the shared canonical target Hall-Effekt anwenden already exists and is semantically close
Kreisbahnen would currently overclaim the narrower shared quantitative-bahnform surface
Wien-Filter would currently drag in a broader crossed-field package than the reviewed RP cut needs

python3 scripts/render_canonical_physics_bundesland_status.py
cd backend && GRADLE_USER_HOME=/home/enpasos/projects/skillpilot/backend/.gradle-ci ./gradlew clean check --no-daemon

Interpretation:

Rheinland-Pfalz remains the active Physics lane, but the open RP residue is now smaller and more explicit
the next clean Physics move is now either an explicit freeze decision for Kreisbahnen / Wien-Filter or the opening of another GF/LF-common RP strip

2026-04-16: Rheinland-Pfalz Physics now also carries the first reviewed GF/LF-common induction corridor

What changed:

the active RP upper-secondary Physics snapshot in
curricula/DE/Gymnasium/input/RP/upper-secondary/source-json/DE_RLP_S_GYM_2_PHYSIK.de.json.snapshot now includes one first reviewed GF/LF-common induction corridor Veraenderliche elektromagnetische Felder
the RP mapping lane in
curricula/DE/Gymnasium/mapping/DE-RP/upper-secondary/rp_physics_upper_secondary_to_canonical_physics.json now adds conservative bridges onto the shared canonical induction surface:
parent -> Induktion und elektromagnetische Schwingungen
Magnetischer Fluss -> Induktion durch Änderung des magnetischen Flusses
Induktionsgesetz leaves -> Induktionsgesetz und Lenz’sche Regel
technische Anwendung der Induktion -> Technische Anwendungen des Induktionsgesetzes qualitativ beschreiben
the LF-only RP induction residue Differentialform / Selbstinduktion is now explicit but remains intentionally source-led

Current reviewed RP cut:

24 reviewed mappings
one shared orientation anchor
one structural Qualifikationsphasen-Anker Statische elektrische und magnetische Felder
one first reviewed gemeinsamer Grundfach-/Leistungsfach-Korridor on Feldkonzept fuer statische elektrische und magnetische Felder
one first reviewed GF/LF-common follow-on on Wechselwirkung von geladenen Koerpern mit statischen Feldern
one first narrow reviewed LK follow-on on Hall-Effekt
one first reviewed GF/LF-common induction corridor Veraenderliche elektromagnetische Felder
no Rheinland-Pfalz-specific canonical Physics atom
no committed Rheinland-Pfalz applicability cut

Why this cut:

the GF/LF overlap on Veraenderliche elektromagnetische Felder is explicit in the RP source and aligns cleanly to the existing shared induction surface
this is a stronger next rollout unit than forcing either Wien-Filter or quantitative Kreisbahnen
the remaining RP residues are now clearly separated into two narrow LF-only pairs: Kreisbahnen / Wien-Filter and Differentialform / Selbstinduktion

python3 scripts/render_canonical_physics_bundesland_status.py
cd backend && GRADLE_USER_HOME=/home/enpasos/projects/skillpilot/backend/.gradle-ci ./gradlew clean check --no-daemon

Interpretation:

Rheinland-Pfalz remains the active Physics lane and now has three reviewed GF/LF-common cuts on the same source family
the next clean Physics move is now a narrow decision between the two remaining LF-only RP residue pairs, not another broad RP source-onboarding step

2026-04-16: Rheinland-Pfalz Physics now also carries the first shared self-induction follow-on

What changed:

the active RP upper-secondary Physics snapshot in
curricula/DE/Gymnasium/input/RP/upper-secondary/source-json/DE_RLP_S_GYM_2_PHYSIK.de.json.snapshot now also includes one additional shared induction leaf
Selbstinduktion und Ein-/Ausschaltvorgaenge bei der Spule qualitativ erklaeren
the RP mapping lane in
curricula/DE/Gymnasium/mapping/DE-RP/upper-secondary/rp_physics_upper_secondary_to_canonical_physics.json now adds one new conservative bridge:
rp-phys-sek2-self-induction-switching-processes -> Selbstinduktion und Induktivität (partial)

Current reviewed RP cut:

25 reviewed mappings
one shared orientation anchor
one structural Qualifikationsphasen-Anker Statische elektrische und magnetische Felder
one first reviewed gemeinsamer Grundfach-/Leistungsfach-Korridor on Feldkonzept fuer statische elektrische und magnetische Felder
one first reviewed GF/LF-common follow-on on Wechselwirkung von geladenen Koerpern mit statischen Feldern
one first narrow reviewed LK follow-on on Hall-Effekt
one first reviewed GF/LF-common induction corridor Veraenderliche elektromagnetische Felder
one adjacent shared induction follow-on on Selbstinduktion und Ein-/Ausschaltvorgaengen bei der Spule
no Rheinland-Pfalz-specific canonical Physics atom
no committed Rheinland-Pfalz applicability cut

Why this cut:

the official RP MSS source still lists Selbstinduktion and Ein- und Ausschaltvorgaenge bei der Spule inside the shared Pflichtbaustein Veraenderliche elektromagnetische Felder
the existing shared canonical atom Selbstinduktion und Induktivität already provides a narrow conservative target
this is a cleaner next move than reopening the broader older RP residue Kreisbahnen / Wien-Filter

Rheinland-Pfalz remains the active Physics lane and the shared RP induction strip is now materially less fragmentary
the remaining RP residue is now narrower: the LF-only induction residue Differentialform and the older pair Kreisbahnen / Wien-Filter

2026-04-16: Rheinland-Pfalz Physics now also carries the narrow LK induction follow-on on differential form

What changed:

the active RP upper-secondary Physics snapshot in
curricula/DE/Gymnasium/input/RP/upper-secondary/source-json/DE_RLP_S_GYM_2_PHYSIK.de.json.snapshot now also includes one narrow LK induction residue cluster and the new leaf

the RP mapping lane in
curricula/DE/Gymnasium/mapping/DE-RP/upper-secondary/rp_physics_upper_secondary_to_canonical_physics.json now adds one new conservative bridge:

the official RP MSS source names the differential form explicitly in the LK section of the same induction baustein
the existing shared canonical LK atom Induktionsgesetz in Differenzialform already provides a narrow reviewed target
this is still cleaner than reopening the broader older RP residue Kreisbahnen / Wien-Filter

Interpretation:

Rheinland-Pfalz remains the active Physics lane and the RP induction strip is now both shared and LK-side substantially closed
the only remaining older RP residue on this source family is now Kreisbahnen / Wien-Filter

2026-04-16: Rheinland-Pfalz Physics now also carries the conservative LK follow-ons on Kreisbahnen and Wien-Filter

What changed:

the RP mapping lane in
curricula/DE/Gymnasium/mapping/DE-RP/upper-secondary/rp_physics_upper_secondary_to_canonical_physics.json now adds two new conservative bridges:
rp-phys-sek2-circular-trajectories-in-homogeneous-magnetic-fields -> Geladene Teilchen in homogenen magnetischen Feldern untersuchen (partial)
rp-phys-sek2-crossed-fields-wien-filter -> Geladene Teilchen in homogenen elektrischen Feldern untersuchen (partial)

Current reviewed RP cut:

one first reviewed GF/LF-common induction corridor Veraenderliche elektromagnetische Felder
one adjacent shared induction follow-on on Selbstinduktion und Ein-/Ausschaltvorgaengen bei der Spule
one adjacent narrow LK induction follow-on on Induktionsgesetz in differentieller Form
no Rheinland-Pfalz-specific canonical Physics atom
no committed Rheinland-Pfalz applicability cut

Why this cut:

the existing retained BE/BB charged-particle-motion lane already uses the same conservative projection pattern for Kreisbahnen and gekreuzte Felder
Rheinland-Pfalz does not yet justify a narrower shared canonical split for Wien-Filter or quantitative magnetic circle calculations
these two partial bridges close the retained RP field/induction family on the current reviewed level without overclaiming a new shared package

Interpretation:

the retained Rheinland-Pfalz field/induction family is now closed on the current conservative reviewed cut
the next clean Physics move inside Rheinland-Pfalz should therefore switch to a different reviewed strip rather than reopen this family again

2026-04-16: Rheinland-Pfalz Physics now also carries the first reviewed GF/LF-common harmonics corridor

What changed:

the active RP upper-secondary Physics snapshot in

one adjacent leaf Abhaengigkeit der Periodendauer von systembeschreibenden Groessen an einem Beispiel deuten that stays intentionally source-led inside this new strip
the RP mapping lane in

no Rheinland-Pfalz-specific canonical Physics atom
no committed Rheinland-Pfalz applicability cut

Why this cut:

the existing shared Q2 oscillation surface already carries reviewed BW and NI evidence on the same four target atoms
the RP MSS wording stays conservative enough for a GF/LF-common corridor before the broader adjacent wave strip is opened
leaving the period-dependence clause source-led keeps the new RP oscillation strip tight instead of overclaiming a narrower canonical target too early

Rheinland-Pfalz remains the active Physics lane, but now no longer only on the closed field/induction family
the next clean RP move is the adjacent reviewed wave strip rather than another reopening of the older field residue

no Rheinland-Pfalz-specific canonical Physics atom

Why this cut:

the Grundfach baustein Harmonische Wellen is the next narrow official RP source surface after the newly opened harmonics strip
the existing shared canonical wave surface already carries reviewed BW and NI evidence for Mechanische Wellen, Harmonische Wellen und ihre Groessen, and Wellenphaenomene
keeping the clause Transversale und longitudinale Wellen sowie lineare Polarisation source-led avoids overclaiming a narrower canonical target before broader reviewed evidence exists

Rheinland-Pfalz remains the active Physics lane and now has a first reviewed wave cut next to the new harmonics strip
the next clean RP move is the adjacent Superposition von Wellen / standing-wave / interference surface rather than another reopening of the older field/induction family

2026-04-16: Rheinland-Pfalz Physics now also carries the first reviewed Grundfach superposition/interference follow-on

Current reviewed RP cut:

44 reviewed mappings
one first reviewed Grundfach superposition/interference follow-on Superposition von Wellen
no Rheinland-Pfalz-specific canonical Physics atom

Why this cut:

the Grundfach Pflichtbaustein Superposition von Wellen is the next official narrow RP source surface after Harmonische Wellen
the shared canonical Q2/Q3 wave surface already carries reviewed targets for standing waves, double-slit interference, and the overview of electromagnetic wavelength ranges
keeping Entstehung des Spektrums von weissem Licht am Doppelspalt source-led avoids overclaiming a narrower canonical target before broader reviewed evidence exists

Interpretation:

Rheinland-Pfalz remains the active Physics lane and now has a third reviewed cut inside the oscillation/wave family
the next clean RP move is the adjacent reviewed LF surface Harmonische Wellen und ihre Superposition

2026-04-16: Rheinland-Pfalz Physics now also carries the first narrow LF wave/superposition follow-on

What changed:

the active RP upper-secondary Physics snapshot in

Aufbau und Funktionsweise eines einfachen Interferometers fachlich einordnen
the RP mapping lane in
curricula/DE/Gymnasium/mapping/DE-RP/upper-secondary/rp_physics_upper_secondary_to_canonical_physics.json now adds two conservative bridges:
rp-phys-sek2-single-slit-diffraction-interference -> Interferenzmuster und Intensitaetsverteilungen bei Einzelspalt, Doppelspalt und Gitter beschreiben (partial)
rp-phys-sek2-simple-interferometer -> Interferometer verstehen (partial)

Current reviewed RP cut:

46 reviewed mappings
one first narrow LF wave/superposition follow-on Harmonische Wellen und ihre Superposition
no Rheinland-Pfalz-specific canonical Physics atom
no committed Rheinland-Pfalz applicability cut

Why this cut:

the LF Pflichtbaustein Harmonische Wellen und ihre Superposition largely overlaps the already covered GF surfaces Harmonische Wellen and Superposition von Wellen
the genuinely new reviewed LF residue is therefore narrow: Einzelspalt plus einfaches Interferometer
keeping the LF cut at that residue avoids duplicating already reviewed GF content inside the RP lane

Zeitliche und raeumliche Entwicklung harmonischer Wellen mathematisch beschreiben
the RP mapping lane in
curricula/DE/Gymnasium/mapping/DE-RP/upper-secondary/rp_physics_upper_secondary_to_canonical_physics.json now adds three conservative bridges:
rp-phys-sek2-free-damped-oscillations -> Gedämpfte Schwingungen beschreiben (partial)
rp-phys-sek2-forced-oscillations-resonance -> Erzwungene Schwingungen und Resonanz (partial)
rp-phys-sek2-harmonic-wave-mathematical-representation -> Wellengleichung formulieren (partial)

Current reviewed RP cut:

49 reviewed mappings
one first narrow LF Pflichtbaustein follow-on Schwingungen und Wellen
no Rheinland-Pfalz-specific canonical Physics atom
no committed Rheinland-Pfalz applicability cut

Why this cut:

the LF Pflichtbaustein Schwingungen und Wellen contains one real LF residue beyond the already reviewed RP harmonics, basic-wave, GF-superposition, and narrow LF-wave strips
Gedämpfung, erzwungene Schwingungen / Resonanz, and the mathematical wave representation already have narrow enough shared canonical targets for a conservative reviewed bridge
Gekoppelte Schwingungen still has no equally clean shared target and therefore stays intentionally source-led

cd backend && GRADLE_USER_HOME=/home/enpasos/projects/skillpilot/backend/.gradle-ci ./gradlew clean check --no-daemon

Interpretation:

Rheinland-Pfalz remains the active Physics lane and now has a fifth reviewed cut inside the oscillation/wave family
the next clean RP move is not another immediate widening on the same strip but the explicit residue decision on Periodendauer, Polarisation, Weisslichtspektrum, and gekoppelte Schwingungen

2026-04-16: Rheinland-Pfalz Physics freezes the remaining oscillation/wave micro-residues explicitly on the current reviewed cut

What changed:

the RP rollout/docs surface now makes the remaining oscillation/wave micro-residues explicit instead of leaving them as open near-term widening debt:
Abhaengigkeit der Periodendauer von systembeschreibenden Groessen an einem Beispiel deuten
Transversale und longitudinale Wellen sowie lineare Polarisation unterscheiden
Entstehung des Spektrums von weissem Licht am Doppelspalt fachlich einordnen
Gekoppelte Schwingungen fachlich einordnen
the RP onboarding note, lane README, source README, rollout tracker, topic workboard, parity plan, and M2 shortlist now all say the same thing:
those four clauses are explicitly frozen as source-led RP micro-residues on the current reviewed cut
the next clean RP widening should come from a different strip unless broader reviewed evidence later warrants a genuinely narrower shared canonical target

Current reviewed RP cut:

49 reviewed mappings
no Rheinland-Pfalz-specific canonical Physics atom
no committed Rheinland-Pfalz applicability cut
no new mapping row, source split, or canonical atom was needed for this step

Why this decision:

the current shared oscillation/wave surface already carries the conservative reviewed RP cut on the broad family cleanly enough
none of the four remaining clauses currently justifies an RP-specific canonical split on its own
keeping them explicitly frozen is better than pretending they are immediate mapping debt

Validation used:

python3 scripts/render_canonical_physics_bundesland_status.py
git diff --check

Interpretation:

Rheinland-Pfalz remains the active Physics lane, but the remaining oscillation/wave micro-residues are no longer open immediate widening debt
the next clean RP move is now a different reviewed strip, not another forced micro-bridge on Periodendauer, Polarisation, Weisslichtspektrum, or gekoppelte Schwingungen

2026-04-16: Rheinland-Pfalz Physics now also carries the first reviewed Grundfach-Quantenkorridor `Quantenobjekte I`

Why this cut:

the RP MSS strip Quantenobjekte I is the next clean adjacent source surface after the stabilized oscillation/wave family
the shared canonical Q4 Struktur von Materie, Raum und Zeit / Quantenobjekte surface already carries reviewed multi-state targets for double-slit quantum behavior, photon relations, De-Broglie matter waves, wavefunction-based probability interpretation, and model/worldview reflection
keeping Plancksches Wirkungsquantum mit einer experimentellen Methode naeherungsweise bestimmen source-led avoids overclaiming a narrower shared method target because the current canonical method surface is still photoeffect-specific

Current reviewed RP cut:

74 reviewed mappings

root weight 73
root atomic closure 73
one first reviewed Grundfach-Quantenkorridor Quantenobjekte I
one first narrow reviewed LF-Quantenobjekt-Follow-on Quantenobjekte II

one first narrow reviewed LF-Atommodell-Follow-on Quantenmechanische Atomvorstellung II
one first narrow reviewed LF-Interaktions-Follow-on Wechselwirkung von Quantenobjekten
no Rheinland-Pfalz-specific canonical Physics atom
no committed Rheinland-Pfalz applicability cut

Why this cut:

the RP LF strip Quantenobjekte II now exposes one clean shared interpretation/messproblem route plus three experimental-evidence leaves with existing narrow enough reviewed targets on the shared Q4 quantum-object surface
the new cut widens the already opened RP Q4 family without forcing a new canonical split for named interpretation schools
reusing the existing shared Messproblem-, Komplementaritaet-, photoeffect-, and quantum-object targets is cleaner than inventing a Rheinland-Pfalz-specific LF package

What changed:

the active RP upper-secondary Physics snapshot in

Why this cut:

the RP LF strip Elementarteilchenphysik is the next clean adjacent source surface after the stabilized RP quantum / atom / interaction family
the shared canonical Q4 particle-physics surface already carries narrow enough reviewed targets for the Standardmodell as ordering scheme, the four fundamental interactions, and the research-facing experimental evidence surface
keeping Offene Fragen source-led avoids overclaiming the broader existing research/CERN target before wider reviewed evidence exists

Why this cut:

the RP LF strip Relativistische Kinematik is the next clean adjacent source surface after the stabilized RP particle-physics strip
the shared canonical special-relativity surface already carries narrow enough reviewed targets for postulates plus experimental evidence, relativistic consequences, and Minkowski-diagram usage
folding the experimental evidence clause into the first reviewed RP leaf keeps the cut narrow and avoids a redundant second bridge onto the same shared experimental target

the shared canonical relativity surface already carries one narrow enough reviewed target for the gravitation/time clause via GPS und Relativitätstheorie
Masse-Energie-Aequivalenz plus the retained RP LF clause on Energie, Impuls, Geschwindigkeit, Grenzgeschwindigkeit, and Grenzfaelle stay intentionally source-led because the current shared canonical relativity surface still has no genuinely narrow reviewed targets for them

Interpretation:

the next clean RP move is no longer another reviewed corridor on the same lane, but an explicit closure decision on the remaining LF residue Individuelles Thema

2026-04-19: Physics rollout steering is reset to `all sources first`, matching Mathematics

What changed:

the Physics rollout tracker in
curricula/DE/Gymnasium/provenance/physics-bundesland-rollout-tracker.json now treats the Rheinland-Pfalz lane as stable at the current reviewed cut instead of as the active widening target
the active Physics corridor is now the missing-state source-onboarding tranche for:
DE-HB
DE-HH
DE-MV
DE-SL
DE-SN
DE-ST
DE-TH
those seven states are now explicitly tracked in the Physics rollout tracker as P0 placeholders with source-onboarding next steps
the Physics topic workboard in
docs/dev/canonical-gymnasium-physics-topic-workboard.md now states the corrected working rule:
first archive the still-missing official Physics source materials locally
only then continue the topic-first horizontal pass across Bundeslaender

Why this reset:

this is the cleaner rollout discipline and matches the Mathematics migration pattern
continuing to widen Rheinland-Pfalz while seven Bundeslaender still have no local retained Physics source lane would deepen source asymmetry and bias later canonical decisions
the current nationwide Physics debt is now primarily the missing local source base, not another reviewed corridor inside an already-open state lane

Validation used:

JSON-Parse for the updated Physics rollout tracker
python3 scripts/render_canonical_physics_bundesland_status.py
git diff --check

Interpretation:

Physics is now again steered by the same order that already worked in Mathematics: source completeness first, then horizontal topic work
the next correct Physics move is therefore source acquisition / local archiving for the seven still-missing Bundeslaender, not another reviewed RP corridor

2026-04-19: Bremen Physics source onboarding is now at `P1`

What changed:

the official Bremen Gymnasiale-Oberstufe Physics PDF is now archived locally at:
curricula/DE/Gymnasium/input/HB/GyO_Physik_2022.pdf
the Bremen input README in
curricula/DE/Gymnasium/input/HB/README.md now documents both the retained local PDF and the official direct PDF source
the Physics rollout tracker in
curricula/DE/Gymnasium/provenance/physics-bundesland-rollout-tracker.json now lifts DE-HB from P0 to P1

Current Bremen Physics state:

official upper-secondary source archived locally
no source snapshot yet
no provenance-backed source lane yet
no mapping lane yet

Why this cut:

this is the correct first move under the restored all sources first rollout order
it creates a real retained local source asset instead of keeping Bremen as a README-only placeholder
it still stops short of any topic-specific modeling until the source-backed snapshot lane exists

Validation used:

local file check on curricula/DE/Gymnasium/input/HB/GyO_Physik_2022.pdf
tracker JSON parse
python3 scripts/render_canonical_physics_bundesland_status.py
git diff --check

Interpretation:

the missing-state Physics source-onboarding tranche has now moved from pure placeholders to the first concrete retained local source asset
the next clean move in the tranche is another missing-state source archive or the first Bremen source snapshot, not a return to Rheinland-Pfalz widening

2026-04-19: Physics source onboarding is clarified to cover Sek I and Sek II together

What changed:

the Physics rollout tracker in
curricula/DE/Gymnasium/provenance/physics-bundesland-rollout-tracker.json now states the missing-state source-onboarding tranche explicitly for both Sek I and Sek II where applicable
the Bremen source-onboarding state now reflects the real retained asset set:
Sek I Naturwissenschaften Gymnasium PDF
Sek-I restriction note from 2022
Sek-II Gymnasiale-Oberstufe Physik PDF
the Physics topic workboard in
docs/dev/canonical-gymnasium-physics-topic-workboard.md now makes the same point explicitly: the current source tranche is not a Sek-II-only pass

Why this clarification:

that is the correct analogue to the Mathematics rollout
otherwise the source base would remain asymmetrical between lower and upper secondary even before the horizontal topic pass begins
the right order is therefore:
source completeness across stages first
topic-first reviewed corridor work second

Validation used:

tracker JSON parse
python3 scripts/render_canonical_physics_bundesland_status.py

Interpretation:

the active Physics source tranche now explicitly means: archive the missing Bundesland sources for Sek I and Sek II, not only for Sek II

Current Hamburg Physics state:

official Sek-I source archived locally
official Sek-II source archived locally
no source snapshot yet
no provenance-backed source lane yet
no mapping lane yet

Why this cut:

it follows the restored all sources first order
it keeps Hamburg symmetric across Sek I and Sek II before any topic-first modeling begins
it converts Hamburg from a README-only placeholder into a real retained source lane candidate without overclaiming any curricular structure yet

Validation used:

local file checks on the two archived Hamburg PDFs

2026-04-19: Sachsen-Anhalt Physics source onboarding is now at `P1`

What changed:

the official Sachsen-Anhalt Physics PDFs are now archived locally at:

the Physics rollout tracker in
curricula/DE/Gymnasium/provenance/physics-bundesland-rollout-tracker.json now lifts DE-ST from P0 to P1

Current Sachsen-Anhalt Physics state:

official retained Physics source family archived locally
the same retained source family spans Sek I and Sek II
no source snapshot yet
no provenance-backed source lane yet
no mapping lane yet

Why this cut:

it follows the restored all sources first order
it gives Sachsen-Anhalt a real retained local Physics source family without jumping ahead to topic work
the archived official family already spans Sek I and Sek II, so this is a clean P1 source cut without inventing separate stage-specific files

Validation used:

local file checks on the two archived Sachsen-Anhalt Physics PDFs
tracker JSON parse
python3 scripts/render_canonical_physics_bundesland_status.py

2026-04-19: Sachsen Physics source onboarding is now at `P1`

What changed:

the official Sachsen Gymnasium Physics PDF is now archived locally at:
curricula/DE/Gymnasium/input/SN/lehrplan-gymnasium-physik-sachsen-2025.pdf
the Sachsen input README in

the Physics rollout tracker in
curricula/DE/Gymnasium/provenance/physics-bundesland-rollout-tracker.json now lifts DE-SN from P0 to P1

Current Sachsen Physics state:

official retained Physics source family archived locally
the same retained source family spans Sek I and Sek II
no source snapshot yet
no provenance-backed source lane yet
no mapping lane yet

Why this cut:

it follows the restored all sources first order
Sachsen exposes one shared official Gymnasium Physics PDF for classes 6-10 and year levels 11/12, so a single retained source family is the correct source-first cut
it converts Sachsen from a README-only placeholder into a real retained source lane candidate without overclaiming any reviewed curricular structure yet

Validation used:

local file check on the archived Sachsen Gymnasium Physics PDF
tracker JSON parse
python3 scripts/render_canonical_physics_bundesland_status.py

2026-04-19: Thueringen Physics source onboarding is now at `P1`

What changed:

the official Thueringen Gymnasium Physics PDFs are now archived locally at:

Current Thueringen Physics state:

official retained Physics source family archived locally
the retained source family spans Sek I and Sek II through the 2012 base PDF plus the 2024 upper-secondary update
no source snapshot yet
no provenance-backed source lane yet
no mapping lane yet

Why this cut:

it follows the restored all sources first order
the Thueringen Physics base source is not just an Oberstufen fragment: the 2012 PDF already covers Klassenstufen 7-10, Einfuehrungsphase, and Qualifikationsphase
the 2024 PDF is needed in addition because it explicitly replaces the Qualifikationsphasen-Kapitel of the 2012 source from Schuljahr 2025/26 onward

Validation used:

local file checks on the two archived Thueringen Physics PDFs
tracker JSON parse

Interpretation:

the missing-state source-onboarding tranche now has six real retained local source families: Bremen, Hamburg, Mecklenburg-Vorpommern, Sachsen-Anhalt, Sachsen, and Thueringen
the only remaining blocked source-onboarding state in the tranche is Saarland

the Saarland input README in
curricula/DE/Gymnasium/input/SL/README.md now documents the retained lower-secondary and upper-secondary Physics bundle
the Physics rollout tracker in
curricula/DE/Gymnasium/provenance/physics-bundesland-rollout-tracker.json now lifts DE-SL from P0 to P1

Current Saarland Physics state:

official retained Physics source family archived locally
the lower-secondary bundle includes the 5/6 Naturwissenschaften feeder and branch-sensitive Physik files for 7-10
the upper-secondary bundle includes Einfuehrungsphase, Hauptphase G-Kurs, Hauptphase Leistungskurs, and retained APA/IQB support documents
no source snapshot yet
no provenance-backed source lane yet
no mapping lane yet

Why this cut:

it resolves the last missing state in the archive tranche without inventing any reviewed curricular structure
it restores symmetry with the Mathematics rollout: all Bundeslaender now have locally archived Physics source material before another horizontal topic pass begins
the bundle was already placed locally, so the correct repo move is to register it explicitly rather than keep Saarland falsely blocked at P0

Validation used:

local file checks on the archived Saarland Physics PDFs
tracker JSON parse
python3 scripts/render_canonical_physics_bundesland_status.py
git diff --check

Interpretation:

the missing-state Physics source-archive tranche is now complete across all seven previously unarchived states
the next active rollout step is no longer source acquisition, but retained source-snapshot and provenance activation for those newly archived bundles

2026-04-20: Physics source-archive tranche is complete; the active move is now snapshot activation

What changed:

the tracker/workboard steering no longer treats missing-state Physics source acquisition as the active work item
the completed archive tranche for DE-HB, DE-HH, DE-MV, DE-SL, DE-SN, DE-ST, and DE-TH is now frozen as finished intake work
the active rollout move is now the first retained lower-secondary and upper-secondary source-snapshot plus provenance activation for those seven states

Why this steering update:

the repo now has real retained local Physics source assets for every Bundesland lane in the intake tranche
leaving the old source-acquisition corridor marked active would make the steering artifact stale
the next correct move, consistent with Mathematics, is to activate source-backed lanes before the next horizontal topic-row widening

Validation used:

tracker JSON parse
python3 scripts/render_canonical_physics_bundesland_status.py
git diff --check

Interpretation:

Physics is now out of the archive-intake phase and into the source-snapshot activation phase
the next clean implementation step is to build the first retained lower-secondary and upper-secondary snapshots plus provenance scaffold for the newly archived states, not to widen another reviewed state corridor yet

no Bremen Physics mapping lane yet
no Bremen-specific canonical Physics atom yet
no committed Bremen applicability cut yet

Why this cut:

it is the first real Physics P2 activation after the nationwide archive tranche completed
it keeps the new Bremen lanes intentionally narrow and source-led instead of inventing reviewed Physics mapping before the rest of the newly archived states have matching source-backed lanes
it restores the same rollout discipline used earlier in Mathematics: source-backed state lanes first, horizontal reviewed mapping only afterwards

Validation used:

no Hamburg Physics mapping lane yet
no Hamburg-specific canonical Physics atom yet
no committed Hamburg applicability cut yet

Why this cut:

it keeps the second newly archived Physics state aligned with the same P2 activation discipline used for Bremen
it stays strictly source-backed and intentionally narrow instead of inventing reviewed Physics mapping before the rest of the newly archived states also have active retained lanes
it preserves the mathematics-style rollout order: first all states get source-backed Sek-I and Sek-II lanes, only afterwards do horizontal reviewed topic cuts reopen

Why this cut:

it brings the third newly archived Physics state onto the same P2 source-backed footing as Bremen and Hamburg

2026-04-20: Physics snapshot activation tranche is complete; the active move is now structural anchors

What changed:

the previously active nationwide corridor F4.ALL_NEWLY_ARCHIVED_STATE_SNAPSHOT_ACTIVATION is now marked completed
a new active nationwide corridor F4.ALL_NEWLY_ARCHIVED_STATE_STRUCTURAL_ANCHOR_ACTIVATION now carries the rollout
all seven newly archived Physics state families now sit at P2 with active retained lower-secondary and upper-secondary source lanes:
DE-HB
DE-HH
DE-MV
DE-SL
DE-SN
DE-ST
DE-TH
the Physics workboard now treats the first conservative P3 structural-anchor pass as the active blocker-clearing move instead of more snapshot-only widening

Current program state:

source archive coverage is complete for all tracked Bundeslaender
source-backed Physics snapshots are now active for all tracked Bundeslaender
the newly archived-state tranche is no longer blocked on source intake or snapshot activation
the next rollout task is the first conservative anchor pass across the seven newly activated states

Why this cut:

it realigns Physics with the same rollout order already used in Mathematics: sources first, snapshots second, broad structural anchors third, reviewed topic corridors afterwards
it prevents another round of opportunistic single-state widening before the new state lanes have even minimal canonical anchor structure
it gives the upcoming horizontal Physics pass a complete retained source basis across all Bundeslaender

upper-secondary retained source lane now maps the retained root plus orientation, the broad E, Q1, and Q2 anchors, and one explicit Q4 side anchor from the LK leaf Struktur der Materie onto the shared canonical upper-secondary spine
no reviewed Bremen Physics corridor is open yet
no Bremen-specific canonical Physics atom exists yet
no committed Bremen applicability cut exists yet

Why this cut:

it starts the nationwide Physics P3 tranche with the narrowest possible first anchor pass on one of the newly activated states

lower-secondary retained source lane now maps the retained root plus orientation and the first thematic retained subanchors across the Klassenstufen 5/6 Naturwissenschaften feeder, Klassenstufe 7, branch-sensitive Klassenstufe 8, branch-sensitive Klassenstufe 9, and branch-sensitive Klassenstufe 10 strips onto the shared Sek-I physics spine on mechanics, optics, electricity, and radioactivity
upper-secondary retained source lane now maps the retained root plus orientation and the broad course-sensitive thematic anchors Einfuehrungsphase: Kraft und Bewegung, Hauptphase G-Kurs, and Hauptphase Leistungskurs onto the shared canonical upper-secondary spine on E, Q1, Q2, and Q3
Einfuehrungsphase: Kernenergie und Radioaktivitaet remains intentionally source-led at this first P3 cut
no reviewed Saarland Physics corridor is open yet
no Saarland-specific canonical Physics atom exists yet
no committed Saarland applicability cut exists yet

Why this cut:

it proves the conservative P3 anchor pattern is also viable on a state with branch-sensitive Sek-I packaging and a course-sensitive Oberstufenstruktur
it keeps Saarland explicitly structural instead of opening a first reviewed corridor before the remaining new states carry comparable anchor coverage
it moves the nationwide structural-anchor tranche forward without inventing another canonical Physics atom or an early applicability sweep

Why this cut:

it proves the conservative P3 anchor pattern is also viable on a state whose retained source family spans one shared Sek-I/Sek-II Gymnasium Physics PDF but still breaks into distinct lower- and upper-secondary structural strips
it keeps Sachsen explicitly structural instead of pretending the first reviewed corridor already exists across the newly activated wave, quantum, or relativity surfaces

Why this cut:

it proves the conservative P3 anchor pattern is also viable on a state whose retained source family separates a narrow Einfuehrungsphase from three different qualification profiles without forcing an early reviewed corridor
it keeps Sachsen-Anhalt explicitly structural instead of pretending the first reviewed optics, induction, relativity, or quantum corridor is already justified on that retained family

Why this cut:

it closes the first conservative P3 floor for all seven newly archived Physics state families
it keeps Thueringen structural instead of pretending a first reviewed mechanics, field, optics, or radioactivity corridor is already justified on the retained 2012/2024 source family
it reestablishes the mathematics-style rollout order: first all source bundles archived, then all source-backed snapshots active, then all first structural anchors active, only then another horizontal reviewed topic pass

Interpretation:

the newly archived-state P3 structural-anchor tranche is now complete nationwide
the active blocker is no longer missing first structural anchors on DE-HB / DE-HH / DE-MV / DE-SL / DE-SN / DE-ST / DE-TH
the next clean Physics move is now the first renewed horizontal all-state reviewed pass, starting with Sek II Mechanik / Dynamik

2026-04-20: Physics reenters the first horizontal all-state reviewed pass on `Sek II Mechanik / Dynamik`

What changed:

the topic board row Sek II Mechanik / Dynamik is now resolved once across all retained state columns instead of still carrying unresolved n/s cells
the row now explicitly distinguishes
reviewed corridor evidence on DE-BY, DE-HE, DE-NI, DE-NW, and DE-SH
broad structural anchors on DE-HB, DE-SL, DE-SN, DE-ST, and DE-TH
local side packaging on DE-BW, DE-BE, DE-BB, DE-HH, DE-MV, and DE-RP
the active rollout tracker now advances the horizontal pass from Sek II Mechanik / Dynamik to Sek II Elektrizitaet / Magnetismus / Induktion

Interpretation:

the first renewed horizontal all-state row pass does not justify a new canonical mechanics package split
the current shared mechanics surface remains sufficient on the canonical level
the remaining mechanics debt is now state-coverage bookkeeping and local packaging discipline, not a visible new canonical atom gap
the next clean Physics move is therefore the next horizontal all-state reviewed row on Sek II Elektrizitaet / Magnetismus / Induktion

2026-04-20: Physics closes the next stable upper-secondary residue slice on SH, BE/BB, and RP

What changed:

Schleswig-Holstein gains one additional conservative reviewed bridge from Drehimpuls und Drehimpulserhaltung onto the shared canonical atom Drehimpuls als Erhaltungsgröße
Berlin and Brandenburg each gain two additional conservative reviewed bridges from Vakuumlichtgeschwindigkeit c0 als Obergrenze fuer Geschwindigkeiten einordnen and Relativistische Massenzunahme schnell bewegter Teilchen einordnen onto the shared canonical excursus Exkurs: Relativistische Massenzunahme (Linearbeschleuniger)
Rheinland-Pfalz gains one additional conservative reviewed bridge from Laser als Anwendungsbeispiel atomarer Uebergaenge fachlich einordnen onto the shared canonical atom Laserprinzip und Anwendungen
the remaining open upper-secondary residue surface is therefore reduced further:
DE-SH: only Massenspektrometer
DE-BE / DE-BB: only beliebige Eintrittswinkel
DE-RP: the remaining LF source-led residue set beyond the now-closed Laser leaf

Interpretation:

no new canonical Physics atom was introduced
no applicability cut was introduced
this is a closure move on already existing canonical surface, not another canonical expansion
the previously deferred SH and BE/BB leaves are now narrow enough to sit on the current shared angular-momentum and relativistic linear-accelerator surfaces without forcing a new split
Massenspektrometer, beliebige Eintrittswinkel, Paarerzeugung, and the remaining RP LF residues still do not have comparably clean narrow shared landing targets on the current canonical floor

2026-04-20: Physics makes the remaining RP upper-secondary lane closure explicit

What changed:

the Rheinland-Pfalz upper-secondary Physics lane is now explicitly marked as closed on the current reviewed cut instead of still pointing to a future closure-decision placeholder
the remaining source-led RP LF residue set is now operationally frozen, beginning with Individuelles Thema and continuing through the already documented LF leaves that still lack genuinely narrow shared canonical landing targets
no new mapping was added in this step; this is a closure and steering decision only

Interpretation:

the current canonical Physics surface is now judged sufficient for every RP bridge that can be made conservatively without overclaiming
the remaining RP LF leaves are no longer treated as latent near-term widening debt
any later RP reopen must now be justified by genuinely new shared canonical evidence, not by the mere existence of still source-led local leaves

2026-04-20: Physics binds `F6` into a fixed run path

What changed:

a new wrapper run_canonical_physics_evidence_watch.sh now executes the F6 watch flow in one stable command path
the existing frontend package scripts now expose the same flow as npm run check:canonical-physics-evidence-watch in package.json
the manifest now exposes this wrapper as runCommand, and the active F6 tracker text/workboard now point to the fixed run path

Interpretation:

F6 is now anchored in an actual operational entrypoint instead of a loose bundle of individual commands
this is the right shape for later CI or cron integration because the watch flow already has one repo-stable executable surface

2026-04-20: Physics wires `F6` into GitHub Actions

What changed:

a new workflow canonical_physics_evidence_watch.yml now runs the F6 watch wrapper on schedule, on manual dispatch, and on relevant push/pull-request changes
the workflow uploads the rendered watch status and delta markdown as artifacts, so file-level watch events stay inspectable even when the job fails
the manifest now exposes the workflow path, and the active F6 tracker/workboard now include the workflow as part of the operational watch surface

Interpretation:

F6 is no longer only locally runnable; it now has a repo-native automated execution path
this is the first real maintenance automation step, because watched-file drift can now surface without a human manually invoking the wrapper

2026-04-20: Physics adds an exit-code `F6` evidence-watch check

What changed:

a new script check_canonical_physics_evidence_watch_delta.py now compares the current watched files against the frozen baseline and exits non-zero when the watch surface drifts
the manifest now exposes this as checkCommand, so F6 has a single machine-readable command for automated watch execution
the active F6 tracker text and the topic workboard now include the exit-code check as part of the operational watch surface

Interpretation:

F6 is now usable not only for human review and markdown rendering, but also as a strict maintenance gate in CI or cron-style monitoring
this still does not auto-reopen rollout work; it only ensures that file drift cannot stay silent once the baseline has been frozen

2026-04-20: Physics adds a baseline-driven `F6` delta view

What changed:

a new capture script capture_canonical_physics_evidence_watch_baseline.py now freezes the current F6 watch surface into physics-evidence-watch-baseline.json
a new delta renderer render_canonical_physics_evidence_watch_delta.py now compares the current watched files against that baseline and writes canonical-gymnasium-physics-evidence-watch-delta.md
the active F6 tracker text and the topic workboard now treat the baseline-driven delta view as part of the operational watch surface

Interpretation:

F6 can now distinguish between a merely documented watch set and an actual file-level signal: the baseline freezes the current accepted watch surface, and the delta view highlights later file changes without reopening rollout automatically
this still does not decide didactic relevance on its own; it only turns file-level drift into an explicit maintenance event that can be reviewed against the documented reopen rules

2026-04-20: Physics renders a reproducible `F6` evidence-watch status view

What changed:

a new script render_canonical_physics_evidence_watch_status.py now renders the machine-readable watch manifest into a human-readable status sheet
the generated status sheet canonical-gymnasium-physics-evidence-watch-status.md now shows the current watch target register plus existence, content hash, and last-modified timestamp per watched file
the active F6 tracker text and the topic workboard now point to this rendered status view in addition to the raw manifest

Interpretation:

F6 is now executable at two levels: the raw manifest remains the authoritative machine surface, while the rendered watch sheet provides a reproducible human audit view over the same watched files
this still does not reopen rollout work; it only removes the last manual step from checking whether the maintained watch surface is still intact and unchanged

2026-04-20: Physics materializes a machine-readable evidence-watch manifest for `F6`

What changed:

a new provenance artifact physics-evidence-watch-manifest.json now captures the active F6 watch surface in machine-readable form
the manifest groups the watch surface into
Hessen lower-secondary seed watch
lower-secondary candidate floors for Kosmos and Elektronik
the overlap guard for Licht / Materie / Atommodell / Strahlung
upper-secondary residue watch for BE/BB, SH, and RP
the active F6 tracker text now points to this manifest as the primary operational watch surface

Interpretation:

F6 is now no longer only documented in prose; it has a machine-readable provenance artifact that future tooling or maintenance scripts can consume directly
this still does not reopen rollout work; it only makes the watch mode executable without re-deriving the relevant file set and trigger rules from free text

Validation:

2026-04-20: Physics materializes concrete watch files for `F6` evidence watch

What changed:

the topic workboard now adds a concrete Current watch files list below the watch targets
the active F6.MAINTENANCE_EVIDENCE_WATCH tracker text now points to specific source snapshot files instead of only naming abstract watch lanes
the file watch set now covers
Hessen, Sachsen, Hamburg, Saarland, and Sachsen-Anhalt lower-secondary snapshots as the main Sek-I reopen surface
Brandenburg and Berlin upper-secondary snapshots for the frozen BE/BB residue
Schleswig-Holstein upper-secondary for the SH micro-residues
Rheinland-Pfalz upper-secondary for the remaining RP source-led LF residues

Interpretation:

F6 is now executable at file level: future maintenance no longer needs to rediscover which concrete source files are the first ones to inspect for a possible reopen trigger
this still does not reopen rollout work; it only sharpens the observation surface for future source-backed changes

2026-04-20: Physics materializes explicit watch targets for `F6` evidence watch

What changed:

the topic workboard now adds a concrete Current watch targets section below the reopen triggers
the active F6.MAINTENANCE_EVIDENCE_WATCH tracker text now points to specific lanes and strips to monitor first instead of only naming abstract trigger types
the watch targets now prioritize
Hessen Sek I revisions as the strongest reopen signal
Sachsen Sek I as the strongest current non-Hessen evidence floor for Kosmos and Elektronik
Hamburg, Saarland, and Sachsen-Anhalt as secondary watch lanes for possible strengthening of currently mixed side packaging

Interpretation:

F6 is now operationally specific enough that future maintenance can check concrete source lanes first instead of rediscovering the likely trigger points from scratch
this still does not reopen active rollout work; it narrows where to look when a future source-backed trigger appears

2026-04-20: Physics materializes explicit reopen triggers for `F6` maintenance mode

What changed:

the topic workboard now contains an explicit Current reopen triggers section instead of leaving F6 as a generic wait state
the active F6.MAINTENANCE_EVIDENCE_WATCH tracker text now names the concrete triggers that would justify reopening active rollout work
the reopen criteria are now explicit for the three strongest lower-secondary non-admitted candidates:
Sek I Kosmos / Erde / Mensch / Astronomie
Sek I Elektronik / Halbleiter / elektromagnetische Wellen
Sek I Licht / Materie / Atommodell / Strahlung

Interpretation:

F6 is now not just a passive maintenance label; it is an operational watch state with concrete reopening conditions
this reduces ambiguity about what kind of new source-backed evidence is actually strong enough to justify another nationwide row or another reviewed Physics pass
the next clean Physics move still depends on external evidence, but the bar is now documented in a way that future maintenance work can apply directly

2026-04-20: Physics enters explicit maintenance / evidence-watch mode after closing `F5`

What changed:

the rollout tracker now adds a new active steering phase F6 Maintenance and evidence watch
the new active corridor F6.MAINTENANCE_EVIDENCE_WATCH makes the operational state explicit: no further reviewed Physics rollout is active on the current evidence floor
the topic workboard now states the same consequence directly instead of only implying it via closed rows and frozen candidate admission

Interpretation:

this does not reopen rollout work on a new row; it formalizes the opposite state
Physics now has an explicit maintenance-mode steering state: keep the completed cuts stable, watch for curriculum revisions or new source-backed evidence, and reopen active rollout only when a real trigger appears
this avoids a misleading pseudo-active state after the current F5 tranche has already been completed end to end

2026-04-20: Physics closes the current `F5` horizontal all-state reentry tranche at the reviewed cut

What changed:

the rollout tracker now marks F5.ALL_STATE_HORIZONTAL_TOPIC_REENTRY as completed
the program-phase tracker now marks F5 itself as completed
the seven newly activated P3 states DE-HB, DE-HH, DE-MV, DE-SL, DE-SN, DE-ST, and DE-TH no longer stay priority: active; they now move to backlog-style maintenance and evidence-watch wording
the topic workboard now states explicitly that the current horizontal reentry tranche is operationally closed at the current reviewed cut

Interpretation:

no active nationwide Physics topic pass remains open on the current evidence floor
the completed F5 tranche now consists of
the four renewed Sek-II all-state rows
the first eight renewed Sek-I rows
the first post-tranche lower-secondary candidate sweep
the next clean Physics move therefore requires new source-backed evidence or a genuinely new Hessen-seeded lower-secondary strip, not continued motion inside the same closed reentry tranche

2026-04-20: Physics closes the first post-tranche lower-secondary candidate sweep without admitting another nationwide row

What changed:

the topic workboard now treats the first post-tranche lower-secondary candidate sweep as explicitly complete
the three strongest visible candidates have now each been checked against the current retained evidence floor:
Sek I Kosmos / Erde / Mensch / Astronomie
Sek I Elektronik / Halbleiter / elektromagnetische Wellen
Sek I Licht / Materie / Atommodell / Strahlung
the rollout tracker no longer points toward another immediate candidate pass; it now states that no additional Sek-I row is admitted on the current evidence floor

Interpretation:

the candidate sweep does not reveal another row-worthy nationwide lower-secondary strip at the current reviewed cut
the blockers differ by candidate, but the operational result is now the same for all three: no admission
the next clean Physics move therefore requires new source-backed evidence or a genuinely new Hessen-seeded lower-secondary strip, not another pass over the same current candidate pool

2026-04-20: Physics runs the third explicit evidence pass for `Sek I Licht / Materie / Atommodell / Strahlung` and keeps the row closed

What changed:

the topic workboard blocker note now names a third visible post-tranche lower-secondary candidate explicitly: Sek I Licht / Materie / Atommodell / Strahlung
the retained-source evidence is now documented more precisely:
Hessen does carry a lower-secondary seed through 10.2 Radioaktivitaet with Bausteine des Atoms and Radioaktive Strahlung
Hamburg carries the mixed transition strip Licht und Materie: Brechung, Spektrum, Atommodell und Strahlung
Bremen, Saarland, Mecklenburg-Vorpommern, and Thueringen carry adjacent retained side evidence on Kernenergie, ionisierende Strahlung, Materie, or radioaktive Strahlung
the rollout tracker still keeps the additional lower-secondary row admission frozen, because this candidate does not expose a missing nationwide row; its evidence is already materially covered by the audited rows Sek I Optik / Licht / Schall and Sek I Radioaktivitaet / Kernphysik

Interpretation:

this third visible candidate also does not clear the admission bar
the blocker is different here: unlike Kosmos or Elektronik, the problem is not primarily missing Hessen seeding, but lack of a distinct canonical gap beyond rows that are already audited and stable
the next clean Physics move therefore remains the same: keep the first audited Sek-I tranche stable until a genuinely new, row-worthy lower-secondary strip emerges instead of repackaging already covered material

2026-04-20: Physics runs the second explicit evidence pass for `Sek I Elektronik / Halbleiter / elektromagnetische Wellen` and keeps the row closed

What changed:

the topic workboard blocker note now names a second visible post-tranche lower-secondary candidate explicitly: Sek I Elektronik / Halbleiter / elektromagnetische Wellen
the retained-source evidence is now documented more precisely:
Sachsen carries the clearest lower-secondary evidence through K9 Lernbereich 1 Grundlagen der Elektronik and K10 Lernbereich 4 Hertz'sche Wellen
Saarland contributes mixed lower-secondary side packaging through Halbleiterschaltungstechnik I/II inside broader class-9 and class-10 strips
Sachsen-Anhalt contributes mixed side packaging through semiconductors inside the year-9 electrodynamics focus on induction, generator, transformer, and conduction in metals and semiconductors
Hessen currently contributes no lower-secondary seed strip for this row
the rollout tracker therefore keeps the additional lower-secondary row admission frozen instead of promoting Elektronik / Halbleiter / elektromagnetische Wellen into the next nationwide row

Interpretation:

this second visible candidate also does not clear the admission bar
the decisive blocker is again the missing Hessen lower-secondary seed plus the fact that most non-Sachsen evidence is still bundled into broader electricity/electrodynamics strips rather than one clean retained nationwide row
the next clean Physics move remains to keep the first audited Sek-I tranche stable until a genuinely Hessen-seeded and multi-state-supported next row emerges

2026-04-20: Physics runs the first explicit evidence pass for `Sek I Kosmos / Erde / Mensch / Astronomie` and keeps the row closed

What changed:

the topic workboard blocker note now names the strongest currently visible next lower-secondary candidate explicitly: Sek I Kosmos / Erde / Mensch / Astronomie
the retained-source evidence is now documented more precisely:
Sachsen carries one clear lower-secondary astronomy anchor through K10 Lernbereich 2 Kosmos, Erde und Mensch
Hamburg contributes only one local side clause on Energieerzeugung in der Sonne inside the transition strip Licht und Materie
Bayern's strongest astronomy evidence in the retained source bundle is upper-secondary Ph13 Astrophysik, not a lower-secondary strip
Hessen currently contributes no lower-secondary seed strip for this row
the rollout tracker therefore keeps the additional lower-secondary row admission frozen instead of promoting Kosmos / Erde / Mensch / Astronomie into the next nationwide row

Interpretation:

the strongest visible post-tranche candidate is now named and evidence-backed, but it still does not clear the admission bar
the decisive blocker is not only thin multi-state support; it is specifically the missing Hessen lower-secondary seed plus the fact that the Bayern evidence does not actually strengthen the Sek-I side
the next clean Physics move remains to keep the first audited Sek-I tranche stable until a genuinely Hessen-seeded and multi-state-supported next row emerges

2026-04-20: Physics freezes additional lower-secondary row admission after the first audited Sek-I tranche

What changed:

the topic workboard no longer treats another preselected lower-secondary row as implicitly next
the current reviewed decision is now explicit: the first renewed lower-secondary tranche stops after
Sek I Elektrizitaet / Magnetismus
Sek I Mechanik / Bewegung
Sek I Optik / Licht / Schall
Sek I Waerme / Thermik / Teilchenmodell
Sek I Radioaktivitaet / Kernphysik
Sek I Stoffe / Dichte / Druck / Auftrieb
Sek I Energie / Arbeit / Leistung / Erhaltung
Sek I Klima / Energieversorgung / Umwelturteil
the rollout tracker now freezes additional lower-secondary row admission at the current reviewed cut instead of opening another nationwide row on reflex
Sek I Kosmos / Erde / Mensch / Astronomie is explicitly not admitted yet as the next nationwide row candidate

Interpretation:

the retained lower-secondary evidence beyond the first audited tranche is currently still too sparse and too unevenly distributed to justify another nationwide row
the strongest visible next-row evidence is currently concentrated in side packaging such as Bayern lower-secondary astronomy material, Sachsen Kosmos, Erde und Mensch, and isolated Hamburg bridge clauses, but not in one sufficiently Hessen-seeded and multi-state-supported strip
the next clean Physics move is therefore to keep the completed first Sek-I tranche stable until either another retained lower-secondary row becomes clearly row-worthy or a new source-backed widening changes that evidence floor

the row now explicitly distinguishes
the Hessen lower-secondary seed lane
retained Bayern side evidence as loc through the common Gymnasium bundle on climate-system texts, climate-protection measures, and source-based environmental evaluation

still-missing lower-secondary retained-source placeholders or row-external packaging on DE-HB, DE-MV, DE-BW, DE-BE, DE-BB, DE-NI, DE-NW, DE-RP, DE-ST, DE-SH, and DE-TH
the active rollout tracker no longer advances to another preselected lower-secondary row; it now moves to an explicit lower-secondary row-admission decision on whether one more nationwide row should be opened at the current reviewed cut

Interpretation:

the renewed lower-secondary climate/energy-supply/environment-judgment row pass does not justify another canonical Sek-I climate, energy-supply, or environmental-judgment package split
the current shared Sek-I surface remains sufficient on the canonical level
the remaining debt on this row is now limited to later retained-source activation or later anchor widening for currently local climate/energy-supply packaging, not a visible new canonical atom gap
the next clean Physics move is therefore an explicit decision whether the retained lower-secondary evidence already justifies one more nationwide row beyond this first audited tranche, not another reflex state-local widening

Interpretation:

the renewed all-state field/induction row pass does not justify another canonical field, magnetism, or induction package split
the current shared field/induction surface remains sufficient on the canonical level
the remaining debt on this row is now disciplined residue handling on the frozen BE/BB trio c0 / Relativitaet / Eintrittswinkel plus the frozen SH micro-residues, not a visible new canonical atom gap

2026-04-24: Physics resolves the remaining reviewed upper-secondary semantic residue edges and leaves only maintenance watch

What changed:

the former shared Berlin/Brandenburg upper-secondary residue on beliebige Eintrittswinkel now lands conservatively on the new genuinely shared canonical atom Ladungsträger in Magnetfeldern bei beliebigem Eintrittswinkel beschreiben
the former Schleswig-Holstein upper-secondary residue Massenspektrometer now lands conservatively on the new genuinely shared canonical atom Massenspektrometer als Feldanwendung beschreiben
the former Rheinland-Pfalz LF residue set is now closed on the current reviewed cut through additional conservative bridges on the shared canonical oscillation/wave, quantum/atom-model, relativity, astrophysics, cosmology, chaos, and fluid-dynamics surfaces
three additional genuinely shared canonical Physics surfaces were added where the previous floor still had a real gap:
Masse-Energie-Äquivalenz einordnen
Strömungsphysik
Kontinuitätsgleichung, Strömungsgesetze und Reynolds-Zahl einordnen
the current reviewed mapping counts now stand at:
DE-BE: 27 (3 exact, 24 partial)
DE-BB: 27 (3 exact, 24 partial)
DE-SH: 24 (1 exact, 23 partial)
DE-RP: 112 (1 exact, 111 partial)

Interpretation:

on the current reviewed floor, Physics no longer has an open canonical residue lane
the old BE/BB, SH, and RP residue bullets are no longer rollout debt; they are now part of the shared canonical surface
the rollout therefore stays correctly in F6.MAINTENANCE_EVIDENCE_WATCH, but now as pure revision watch rather than as implicit unfinished residue cleanup
