The ADR index (.abcd/development/decisions/adrs/README.md) ends at the adr-44 row while adr-45 is accepted (2026-08-20) and cited as settled law by six live records (the invariants brief, itd-114, spc-33, .abcd/work/issues/README.md, two open issues, DECISIONS.md). 37 ADR files vs 36 index rows — exactly one missing. The index is the declared hand-maintained roll-call (adrs/README.md) and is not among index_drift's four registered indexes, so it is structurally ungated. Third recurrence of this class in the same table (after resolved iss-296 and iss-374), which iss-38's decision (hand-kept indexes must be deleted or gated) predicts.

• adr-44abcd never mutates a remote uninvited, and identity derives from caller-local facts
• adr-45Record ids are timestamp-numeric, capture-stable, and never allocated by looking at the maximum

• iss-38hand-maintained index drift: intents/README.md corpus listings have drifted from the filesystem; commands/README.md lists three of the seven plugin verb files; internal/README.md still describes core as two capabilities with adapter/scanner as a planned seam; the repo README Layout omits skills/ from the plugin surface. Detector (per adr-5 derive-dont-store): hand enumerations of sibling files are generated or deleted — a lint flags a README that enumerates directory contents by hand, or the enumeration is emitted by tooling with a drift test. Acceptance corpus: the four stale indexes above.
• iss-296The hand-maintained ADR index table (.abcd/development/decisions/adrs/README.md) ends at adr-42 and omits committed records adr-43 and adr-44; the record-lint index_drift rule registers four indexes but not the ADR index, so this largest hand index is ungated. Same file: .abcd/work/rulesets/README.md says 'seven required status checks' where main-protection.json now lists eight (external-review added)
• iss-374The hand-maintained ADR index lists adr-44 as proposed but the record frontmatter is accepted; the index drifted after status was flipped without updating the index
• iss-2608220150157511Merge contention is structural in the shared registers, not the prose: append logs (.abcd/work/DECISIONS.md, 154 changes; the decomposition-calibration corpus, conflicted 2026-08-22) and the lint-gated indexes that index_drift forces every branch to co-edit (brief/06-delivery/03-out-of-scope.md drafts index, conflicted the same day; 04-surfaces/README.md; decisions/adrs/README.md; intents/README.md; release/surface.json). The fix shape for the indexes is already written down: the enumeration command in out-of-scope.md derives the list from the filesystem, so the committed copy could become generated-at-build and the lint compare against the derivation instead of a hand-edited region. Append logs tolerate union merges; the indexes do not
