Canonical Gymnasium Mathematics DE Expansion Plan

Snapshot: 2026-03-30

This plan focuses on one target:

  • curricula/DE/Gymnasium/canonical/DE_DEU_S_GYM_CANONICAL_MATHEMATIK.de.json should converge toward reviewed coverage for all 16 German Bundeslaender without cloning canonical goals per state.

The landscape JSON itself should stay pure curriculum data. Rollout planning, steering, and progress tracking should live next to it, not inside it.

Persistent control setup

Use three persisted artifacts:

  1. plan document
  2. docs/dev/canonical-gymnasium-math-de-expansion-plan.md
  3. purpose: stable narrative, rollout phases, rules, and exit criteria

  4. machine-readable tracker

  5. curricula/DE/Gymnasium/provenance/math-bundesland-rollout-tracker.json
  6. purpose: single source of truth for per-state rollout phase, next step, and lane references

  7. quick status view

  8. docs/dev/canonical-gymnasium-math-bundeslaender-status.md
  9. purpose: easy-to-scan overview for humans
  10. generation: python3 scripts/render_canonical_math_bundesland_status.py

  11. topic workboard

  12. docs/dev/canonical-gymnasium-math-topic-workboard.md
  13. purpose: canonical-first decision board by topic and Bundesland
  14. use: one row per high-level topic, one state cell per Bundesland, plus explicit canonical gaps and next action

Working rule:

  • update the JSON tracker first
  • regenerate the Markdown quick view second
  • update the topic workboard whenever the active implementation unit changes
  • keep plan, tracker, quick view, and workboard aligned

This keeps the plan persisted, diffable, and simple to review in PRs.

Why this setup

This setup keeps concerns separated:

  • the canonical math landscape remains didactic source data
  • the rollout tracker remains operational metadata
  • the quick view remains the simplest place to answer:
  • which states are already on the canonical spine
  • what phase each state is in
  • what the current nationwide implementation score is

It also avoids hiding planning state in a huge curriculum JSON where operational progress would be hard to inspect and easy to forget.

Steering model

The rollout should now be steered in a stricter order than the earlier mainly bundeslandwise queue.

Target stance:

  • the canonical DE mathematics graph is the pedagogical source of truth
  • Bundesland mappings are evidence and coverage for that graph, not the primary design driver
  • Bundesland learner-facing trees should later be projections of that graph, not competing authored content universes

Operational consequence:

  • the primary implementation unit is now a canonical corridor
  • the state tracker remains necessary, but it measures projection/readiness on the canonical spine, not the pedagogical quality of the canonical graph itself

Canonical-first execution order:

  1. refine one canonical corridor until its atomic inventory and progression are pedagogically round
  2. map that corridor against all 16 state curricula and classify reviewed bridges as exact, partial, not_applicable, or state_local
  3. only then stabilize state-scoped composition views and learner-facing cluster shapes for the affected scopes

Authoring rule for new canonical atoms:

  • add a canonical atom only if it improves the shared DE mathematics graph pedagogically
  • do not add canonical atoms merely to mirror one state's packaging, wording, or table layout
  • if a source item is only state-specific packaging, keep it in mapping/provenance or later state composition, not in the canonical core

This means the canonical DE view must not become the raw union of all reviewed state atoms. It should instead become a curated, didactically closed competence model whose state-specific projections are then derived as tightly as possible without violating local curriculum constraints.

Progress log

2026-03-30 / Steering model recalibrated

Executed work:

  • tightened the nationwide math rollout policy from a mainly bundeslandwise queue to a canonical-first corridor-steering model
  • kept the existing state tracker as operational readiness metadata, but clarified that canonical pedagogical quality is a separate first-order concern
  • introduced an explicit canonical corridor register in the machine-readable tracker and the generated quick status view
  • set the new active corridor framing to:
  • Sek I J10 function families
  • Sek I J10 bodies, volumes, and plausibility
  • Sek II analysis
  • Sek II geometry and linear algebra
  • Sek II stochastics
  • moved the early Sek I foundations pass into the canonical next-wave register instead of treating it only as diffuse state-local cleanup

Resulting rollout effect:

  • the project now has an explicit answer to "what should be designed canonically next?" before asking "which Bundesland should move next?"
  • the state tracker remains useful, but it is now clearly subordinate to corridor-first canonical design
  • future state views can converge more cleanly toward curated composition views over the canonical graph instead of broad state-shaped tree drift

2026-03-21 / Step 1 completed

Executed work:

  • verified the active five-state mathematics base against actual repo evidence
  • archived the first Brandenburg mathematics source bundle:

  • mapped Berlin upper-secondary phase anchors E, Q1, Q2, Q3, Q4 onto the canonical upper-secondary phase spine as structural partial bridges
  • kept the structural-anchor step intentionally narrow:
  • no new reviewed corridor claims

Coverage target

For this rollout, a Bundesland counts as operationally covered only when all of the following are true:

  • state-owned math source material is archived under curricula/DE/Gymnasium/input/<STATE>/...
  • the relevant source snapshots and provenance entries are active
  • the canonical math graph has reviewed overlap for both structural anchors and at least one didactically closed corridor
  • state-specific visibility is represented through canonical applicability, not cloned goal trees
  • the remaining delta is narrow enough that the state can be widened corridor by corridor without rethinking the whole spine

Long-term target:

  • every state reaches at least broad reviewed lower-secondary and upper-secondary coverage on the same canonical math spine
  • the final per-state runtime behavior is driven by mappings, provenance, and compiled applicability

Program phases

The overall rollout should be managed in clear phases.

Phase 0. Tracking scaffold

Deliverables:

  • persisted plan
  • persisted JSON tracker
  • generated quick view
  • agreed phase scale for all states

Exit criteria:

  • every Bundesland has a tracker row
  • the team can update status without touching the canonical math JSON

Phase 1. Stabilize the active five-state base

Scope:

  • DE-HE
  • DE-BY
  • DE-NW
  • DE-NI
  • DE-BW

Deliverables:

  • keep existing active mapping lanes stable
  • keep source, provenance, and applicability references clean
  • remove ambiguity about which of these states are only pilot corridors and which already have broad coverage

Exit criteria:

  • every active state is at least P4 on the common state scale
  • DE-HE and DE-BY stay the current broad-coverage reference lanes

Phase 2. Source onboarding for the remaining eleven states

Scope:

  • DE-BB
  • DE-BE
  • DE-HB
  • DE-HH
  • DE-MV
  • DE-RP
  • DE-SH
  • DE-SL
  • DE-SN
  • DE-ST
  • DE-TH

Deliverables:

  • source archive lanes under curricula/DE/Gymnasium/input/<STATE>/
  • first state-specific math source inventory notes where needed
  • mapping-lane scaffolds under curricula/DE/Gymnasium/mapping/DE-<STATE>/

Exit criteria:

  • every remaining state has moved from placeholder-only to archived-source readiness
  • no state is blocked on "we still need to decide where the source bundle belongs"

Phase 3. Nationwide first-corridor pass

Deliverables per new state:

  • active source snapshot and provenance registration
  • canonical structural anchors on the shared spine
  • one reviewed corridor with explicit mappings

Preferred corridor order:

  • structural anchors first
  • then functions
  • then stochastics
  • then geometry/algebra

Exit criteria:

  • all 16 states reach at least P4
  • the canonical math landscape carries reviewed applicability for every onboarded state

Phase 4. Lower-secondary breadth

Deliverables:

  • widen each state beyond the first reviewed corridor across the shared J5-J10 grid
  • close obvious prerequisite strips so lower-secondary learner navigation is not just corridor-deep

Exit criteria:

  • every state has broad reviewed lower-secondary coverage on the canonical spine

Phase 5. Upper-secondary breadth

Deliverables:

  • widen upper-secondary state coverage corridor by corridor
  • keep Hessen as the reference donor, but validate every other state against the shared upper-secondary math structure

Exit criteria:

  • every state has broad reviewed upper-secondary coverage
  • the remaining open work is edge cleanup or special-state detail, not missing core curriculum regions

Phase 6. Cutover and maintenance

Deliverables:

  • stable applicability behavior for all states
  • stable learner-facing selection into the DE-level canonical math landscape
  • clear maintenance workflow for future curriculum revisions

Exit criteria:

  • every state reaches P6
  • the nationwide tracker no longer reflects rollout debt, only maintenance deltas

State phase scale

Use one simple scale per Bundesland.

State phase Score Meaning
P0 0% Placeholder only: README/source links, no active math rollout lane
P1 15% Source archived in the DE-level input lane
P2 30% Source snapshot and provenance active
P3 50% Structural anchors mapped on the canonical spine
P4 65% First reviewed corridor mapped and usable
P5 85% Broad state coverage across the main math spine
P6 100% State cutover ready on the canonical math landscape

Interpretation:

  • P4 is the threshold for "real onboarding happened"
  • P5 is the threshold for "this state is no longer just a narrow pilot"
  • P6 should be rare until the final nationwide cleanup phase

Steering rules

  • Do not store rollout status inside DE_DEU_S_GYM_CANONICAL_MATHEMATIK.de.json.
  • Do not broaden many subjects in parallel before the math tracker shows nationwide momentum.
  • Prefer one new didactically closed corridor over a broad, weakly reviewed state import.
  • Prefer state-independent canonical goals plus state-specific applicability over state-specific goal duplication.
  • Keep Sek I normalized to the shared J5-J10 grid even if a source curriculum uses G8 / G9 labels differently.
  • Use the same tracker fields for every state, even if one state currently has only placeholder status.

Program interpretation:

  • the repo is beyond pure pilot mode for math

  • the shared Brandenburg/Berlin upper-secondary Q3 geometry strip now also has Brandenburg- and Berlin-side provenance splits that separate the previously broad line/plane source anchors into parametric-line work, coordinate/normal-form plane work, cross-form plane descriptions, and first line/plane relation checks without widening the nationwide canonical phase picture
  • the Berlin side of the same Q3 strip now also mirrors the later Brandenburg plane-anchor refinement by separating normal-vector work from coordinate-form work before the cross-form plane bridge, still without widening the nationwide canonical phase picture
  • the Brandenburg side of the same Q3 strip now also has a second and third provenance refinement that separates vector/coordinatization work from scalar-product/length/angle work, feeds the local projection intuition lane from the scalar-product anchor, and now also isolates coordinate-form work from the normal-vector anchor before the cross-form plane bridge
  • the Berlin side of the same Q3 strip now also mirrors that vector-anchor refinement by separating pure vector/coordinatization work from scalar-product/length/angle work and by feeding the angle follow-on explicitly from the new scalar-product anchor without widening the nationwide canonical phase picture

  • the SH Sek-I lane now also operationalizes the still-generic Proportionale Funktionen / Antiproportionale Funktionen / Lineare Funktionen atoms closer to their active canonical proportional, inverse-proportional, and linear-function targets, so the coarse raw table-label function-family residue is smaller again without changing the nationwide canonical phase picture

  • the SH Sek-I lane now also operationalizes the still-generic Dreisatz / Proportionale Funktionen und Dreisatz / Quadratische Funktionen und Gleichungen / Quadratische Funktionen nodes closer to their active canonical rule-of-three and quadratic corridor targets, so the remaining SH residue shifts again from raw table-label parents toward the few still-broad corridor-parent nodes

  • the SH Sek-I lane now also operationalizes the still-generic Jahrgangsband 5/6 / Jahrgangsband 7/8/9 year-parents closer to their active canonical early- and later-Sek-I anchors, so the remaining SH residue shifts away from raw band labels toward the top-level SH root or a new explicit follow-on strip
  • the SH Sek-I lane now also operationalizes the still-generic top-level Mathematik Sekundarstufe I root closer to the refined early-/later-/late-Sek-I progression, so the remaining SH residue shifts away from raw source-table root wording toward opening a new explicit follow-on strip
  • the SH lane now also opens its first explicit upper-secondary follow-on strip by splitting Einfuehrungsjahr: Geometrie into vectors in R2/R3, lines, and line relations and mapping them onto the canonical space/line corridor, so the next SH residue shifts from Sek-I parent cleanup toward similarly explicit Sek-II phase-table cells such as Q1 geometry or E analysis

Update workflow

  1. update curricula/DE/Gymnasium/provenance/math-bundesland-rollout-tracker.json
  2. run python3 scripts/render_canonical_math_bundesland_status.py
  3. review the generated docs/dev/canonical-gymnasium-math-bundeslaender-status.md
  4. update docs/dev/canonical-gymnasium-math-de-expansion-plan.md
  5. commit plan, tracker, and generated status together when the rollout picture changed

Suggested next concrete move

Keep the tracker stable and use it to drive math work in this order:

  1. broaden Nordrhein-Westfalen from its now atom-anchored lower-secondary prerequisite/functions plus upper-secondary analysis, refined GK integral theorem/antiderivative/stock-effect split, exact retained exponential split, and E-phase/Q-phase geometry/linear-algebra pilot coverage toward broader state coverage, but do so via the retained E-phase power/polynomial split or another equally explicit NRW source corridor rather than reopening structural parent cleanup inside the already reviewed NRW snapshots
  2. keep Baden-Wuerttemberg and Niedersachsen stable at their now exhausted explicit lower-secondary pilot-snapshot / strip level unless additional retained source corridors are imported intentionally
  3. keep Brandenburg, Berlin, and Schleswig-Holstein stable at their explicitly source-exposed residue level unless a genuinely clearer local follow-on appears that changes the nationwide rollout picture

That makes nationwide progress visible without overloading the canonical landscape file with project-management metadata.
