Purpose

One coordinated owner-level steering clarification under rule-set revision 4 (no new global R-rule, new acceptance gate or product feature). Identify code-facing claims that cannot be justified on the current backend and specify the existing owners' fail-closed obligations.

Scope / coverage

• Canonical docs/current-capabilities.json states split component presence, raft-rs cadence, compaction and integrated recovery.
• Capabilities generator, generated page and source-coupled consistency checker updated together.
• Current replication architecture and operations guidance no longer promise automatic raft-rs recovery on the basis of predecessor proofs.
• PostgreSQL-wire owner records a real DO UPDATE→orReplace semantic defect and public typed-refusal boundary, including literal and uncertain-COMMIT obligations.
• Existing documentation lifecycle owner defines proof-bound claims and a derived, not duplicated convergence snapshot.
• Sealed Quest evidence, actual runtime semantics, R8 / RS-Raft closeout criteria unchanged.
• Coordinated follow-ups: active RS-Raft epic snapshot branch docs/rs-raft-convergence-snapshot-20261026 and lab recovery branch docs/disposable-recovery-20261026 in its separate repo.

Concrete unfixed source gaps (do not close with docs)

• src/partition/partition-snapshot-cadence.js returns COMMITTED_LOG_UNSUPPORTED for file-backed leaders. Automatic raft-rs snapshot/compaction/recovery still needs an owner-level implementation and exact-candidate proof.
• src/query/pg/pg-translate.js maps PostgreSQL ON CONFLICT DO UPDATE to replacement; a code repair must implement correct semantics or typed refusal before side effects. Public literal and transaction-unknown-outcome proofs remain open.

Verification performed

• Regenerated proposed public capability page in memory from the modified generator and JSON: byte-exact.
• Node ESM syntax checks for modified generator and capability checker: both passed.
• Exact-head GitHub Actions change-gate #40319727857 on 78052505ce375b50ba94b812adc8b67b9e5f5084: success. Generated metadata is current; npm run check passed its fast-static audit and all 179 selected test files (4,750 runner-reported assertions, zero failed files).
• Added regression tests for source-owner drift and derived fixture inputs from the capability checker's own file list. The two generated test-metadata projections were updated to CI-exact bytes.
• GitHub compare: 11 files; no production runtime code changed.
• Not performed: physical lab or R8/canonical distributed-service verification. These remain separate, unclosed requirements.

Integration coordination

Historical predecessor tests remain valid in their original scope. The active RS-Raft integration branch is not changed or resumed by this PR. Preserve existing accepted repairs and the 25 October stop instruction.
