Steering model

• Primary work unit: maintenance_delta
• Canonical view rule: Treat the canonical DE mathematics view as a curated pedagogical source of truth, not as the raw union of all state-specific atoms.
• State view rule: Treat Bundesland views as projections that stay as close as possible to the canonical view while omitting atoms that would violate the local curriculum.
• Count gate rule: states outside the Hessen +-20% stage-count corridor are operationally capped at P5 / subtree_adopted until the corridor passes.
• Execution sequence:
• Archive or refresh the retained state source lane first, then narrow the affected curriculum delta to mappings, provenance, applicability, and composition scopes.
• Only touch the reviewed canonical atoms and the smallest state-scoped mathematics composition views whose learner-facing tree shape really changes.
• Re-run applicability, composition-view validation, canonical math scope coverage, status rendering, and CI before merging the maintenance delta.
• Canonical atom admission:
• Add a canonical atom only if it improves the pedagogical completeness of the shared DE math graph.
• Do not add canonical atoms only to mirror one state's packaging, table layout, or wording.
• Prefer canonical subtree quality over short-term mapping convenience.

Canonical corridor register

Corridor	Status	Focus states	Next step
SEK1.J10.FUNCTION_FAMILIES Sek I J10 function families	completed	DE-BY, DE-BW, DE-SH, DE-NI, DE-SN	Treat the Sek-I J10 function-family sweep as closed for now: freeze the visible F1-F5 surface including the late J10 continuation corridor, accept broad 9/10 or year-10 function lanes as resolved where the source remains mixed, and reopen only if a later reviewed lane or validator finding forces a real shared canonical gap beyond the current function surface.
SEK1.J10.5D_GEOMETRY Sek I J10 bodies, volumes, and plausibility	completed	DE-BY, DE-BW, DE-SH	Treat the Sek-I J10 bodies / volumes / plausibility sweep as closed for now: freeze the visible G2-G7 surface together with the late J10 body and plausibility corridor, accept broad year-10 body bands as resolved where the source remains coarse, and reopen only if a later reviewed lane or validator finding forces a real shared canonical gap beyond the current geometry surface.
SEK2.ANALYSIS Sek II analysis and integral / exponential deepening	completed	DE-HE, DE-NW, DE-SH, DE-BW, DE-BY, DE-NI, DE-SN	Treat the Sek-II analysis full sweep as closed for now: freeze the visible AN2-AN4 surface, keep residue control quiet, and reopen only if a later reviewed lane or validator finding forces a real shared canonical gap.
SEK2.GEOMETRY_LINEAR_ALGEBRA Sek II geometry and linear algebra	completed	DE-NW, DE-BB, DE-BE, DE-SH, DE-BW, DE-BY, DE-SN, DE-RP	Treat the Sek-II geometry / linear-algebra full sweep as closed for now: freeze the visible AGV1-AGV5 and LM2-LM5 surfaces, accept broad overview lanes as resolved where the source remains corridor-level, and reopen only if a later reviewed lane or validator finding forces a real shared canonical gap.
SEK2.STOCHASTICS Sek II stochastics	completed	DE-NW, DE-BE, DE-BB, DE-SH, DE-NI, DE-BW, DE-BY, DE-SN	Treat the Sek-II stochastics full sweep as closed for now: freeze the visible ST2-ST5 surface plus the explicit ST3 boundary, and reopen only if a later reviewed lane or validator finding forces a real shared canonical gap.
SEK1.FOUNDATIONS Sek I lower-secondary breadth	completed	DE-BW, DE-BY, DE-BE, DE-BB, DE-NI	Treat the nationwide lower-secondary breadth sweep as closed for now: all top-level Sek-I rows are resolved once, freeze the visible A1-A4, F1-F5, G2-G7, and D1-D5 surfaces, and shift the active nationwide completion work to applicability, learner-facing scope selection, and P6/F6 cutover cleanup.

Atomic count corridor

Hessen (DE-HE) is the reference lane. All other states should stay within +-20% of the Hessen stage counts.

Operational gate: out-of-corridor states are capped at P5 / subtree_adopted. Full three-stage failures escalate to active, partial failures to next_wave.

Immediate queue

• DE-BW (P5, active): Bring Baden-Wuerttemberg into the Hessen atomic-count corridor on Sek I, Sek II (GK), Sek II (LK): start with learner-facing mathematics composition views and applicability, then narrow any remaining gap through the smallest mapping/provenance delta that explains the missing visible atoms; do not treat the lane as cutover_ready until all stage counts stay within +-20% of Hessen. State-specific handling: Resolve the active Baden-Wuerttemberg quality corridor without overmapping: treat the official BP2016 source-extraction as source-internally closed, keep the 33 HE-covered canonical atoms that are not explicit in BW as documented state-view exclusions unless later source evidence contradicts this, route the 78 stage-shifted atoms through Sek-I closure/applicability instead of Kursstufen overmapping, and then reconcile the remaining learner-facing atom-count gap through reviewed applicability and composition-view scope rather than synthetic BW Kursstufe mappings.
