Chemistry evidence-watch maintenance review — 7 October 2026

Exact reviewed delta

The local Chemistry evidence watch reported changed=2 added=0 removed=0 after the independently reviewed Chemistry 18-goal integration. The two watched inputs are the canonical Chemistry JSON and the Bavaria source-mapping review. Their old watch hashes match the immutable pre-integration snapshots; their current bytes match the guarded integration plan exactly.

The canonical graph retains all 479 nodes, including 378 curricularAtomic goals, with the same IDs, dependencies, containment and applicability. The normalized watch delta consists of three already reviewed goal corrections:

  • fd309753: aqueous acidity/basicity depends on the relative predominance of hydronium or hydroxide, rather than their mere presence; DE and EN agree.
  • 22133f29: EN explicitly retains the aqueous-solution scope already stated in DE.
  • 9751b6d8: DE/EN name reversibility of proton transfer, and direct source provenance points to the already reviewed Bavarian C10-NTG.2.8 component.

The Bavaria review appends exactly two direct child routes. The 597ac03c route covers the acid/base structural-suitability component of C10-HG_SG_MUG_WWG_SWG.4.6 and remains partial; its reversibility sibling is separate. The 9751b6d8 route covers the qualitative reversible-proton-transfer component of C10-NTG.2.8. All prior mapping rows and all other source decisions and global summaries are unchanged. These component bindings do not close the entire source groups or other open scientific work.

The four new PNG bindings belong to the separately reviewed visualization lane. The unchanged watch contract excludes image presentation metadata from its canonical evidence hash.

Bounded baseline acknowledgement

Only the two corresponding baseline records and updatedAt advance. The other 144 complete baseline records remain exact, with the same 146 watched paths. The manifest, normalization algorithm, checker and workflow remain unchanged; future unacknowledged deltas still fail.

The technical receipt records the exact changed fields, existing reviewed plan operations and both old/current watch hashes. The complete prior baseline is retained unchanged. The actual guarded scientific integration remains the integration lineage; this maintenance acknowledgement creates zero new scientific reviews or completions. Current strict M7 totals require the central report. Human approval, practical trials and release acceptance remain separate.

Local verification

The unchanged bash scripts/run_canonical_chemistry_evidence_watch.sh completed with Exit 0 at 09:30:15 UTC, including its self-test, changed=0 added=0 removed=0 and CHEMISTRY_EVIDENCE_WATCH=OK. Both watch views were regenerated natively. The completed command receipt records the actual terminal result. This is local evidence; a new commit and GitHub run must verify CI separately.
