Canonical Gymnasium Chemistry Baden-Wuerttemberg Cutover Readiness Audit

Date: 2026-05-12

Decision

DE-BW Chemistry is cutover-ready on the canonical Gymnasium Chemistry route.

The operational learner route is the shared Gymnasium (DE) root with the canonical Chemistry child landscape and the matching DE-BW GK/LK composition view. The retained Baden-Wuerttemberg source-extraction landscapes remain archive-only evidence surfaces.

Evidence

  • Lower-secondary and upper-secondary source extractions are registered:
  • curricula/DE/Gymnasium/input/BW/lower-secondary/source-extraction/DE_BW_CHEMIE_SEKI_BP2016_V2.source-extraction.json
  • curricula/DE/Gymnasium/input/BW/upper-secondary/source-extraction/DE_BW_CHEMIE_SEKII_BP2016_V2.source-extraction.json
  • Reviewed source-to-canonical mappings are clean and now have runtime mapping files:
  • curricula/DE/Gymnasium/mapping/DE-BW/lower-secondary/bw_chemistry_lower_secondary_to_canonical_chemistry.json
  • curricula/DE/Gymnasium/mapping/DE-BW/upper-secondary/bw_chemistry_upper_secondary_to_canonical_chemistry.json
  • The canonical learner-facing views exist for both course profiles:
  • de-bw-gym-chemistry-gk
  • de-bw-gym-chemistry-lk
  • Source-extraction landscapes are classified by runtime as compatibility-only archive surfaces through the source-landscape registry fence.

Runtime Notes

Baden-Wuerttemberg does not currently expose an active committed legacy Chemistry learner route comparable to the Hessen or Bayern legacy trees. The required runtime cutover check is therefore the retained-source fence plus runtime mapping discovery:

  • retained source landscapes load from the real source registry
  • retained source landscapes resolve to DE-BW
  • retained source landscapes are compatibility-only
  • GoalMappingService discovers the runtime mappings for both lower-secondary and upper-secondary source landscape IDs

Verification

Targeted backend coverage:
