Merge Risk: 🟡 Moderate · up to This change retires legacy PostgreSQL extensions, but existing databases with extension-dependent objects may not be handled safely, and the documented preflight can fail when pg_cron is unavailable. Merge should wait for these bounded migration and operator-guidance issues to be fixed or explicitly accepted. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

documentation, relevant ADR, doctoring documentation, and CHANGELOG to document
the retirement contract enforced by the migration: required preconditions,
failure behavior, rerun behavior, and the RESTRICT-based rollback boundary
around http and pg_cron removal. Include the operator recovery steps for
remaining cron jobs or helper functions, referencing the migration’s
pg_catalog.pg_extension check, cron.job validation, to_regprocedure checks, and
DROP EXTENSION statements.

In `@ARCHITECTURE.md`:
- Around line 66-71: Update the legacy-extension retirement migration’s
preflight to fail closed on pg_depend entries for extension members and routines
explicitly depending on http or pg_cron, and add smoke fixtures covering both
cases. Revise ARCHITECTURE.md (66-71, 104-108), docs/OPERABILITY.md (49, 63),
docs/adr/legacy-postgresql-extension-retirement.md (19),
docs/doctoring/legacy-postgresql-extension-retirement.md (17), README.md (316),
and CHANGELOG.md (41) so their preservation guarantees require these dependency
checks. Keep the existing RESTRICT, transaction, timeout, schedule, signature,
and table-preservation behavior unchanged.
In `@docs/OPERABILITY.md`:
- Around line 22-31: Update the recommended preflight queries so the cron.job
listing runs only when pg_cron is installed and cron.job exists, using an
initial pg_extension or to_regclass('cron.job') check and a conditional
execution mechanism while preserving the existing job-list query.

Dismissed as predecessor-head coverage evidence only. This review is bound to a1c8a39 and blocks solely on failed coverage evidence there. Current unchanged contributor head 1b28306 has terminal-success coverage-evidence and opencode-review checks. Dismissal removes stale negative evidence only; it does not provide or substitute for the live ruleset's required qualifying non-author approval of the last push. The branch remains non-mergeable/diverged from protected main and its overlapping README/ARCHITECTURE/CHANGELOG surfaces remain writer-blocked by retained no-PR branch agent/checkpoint-audit-trail-v3, so no ancestry/source repair is attempted in this invocation.

…main Preserve the fail-closed existing-volume retirement migration and realistic smoke evidence while taking the current protected tree as source authority. Drop stale README/architecture/changelog copies, keep the retirement ADR Proposed, and narrow documentation contracts to this lane's migration/operability/doctoring surfaces.
Repair the current repository ADR naming invariant without rewriting history: reserve the next unclaimed live prefix for the legacy-extension retirement decision and make its documentation regression assert the actual bounded authority wording.

Current-head repair finding on 664987f20020a0d7c7d04f396466755569f18191: CI 34693710073 is not GREEN. Python 3.10/3.12 unit-test lanes pass, while Coverage, docstrings, lint, and package fails specifically at Enforce line coverage; compile/lint/docstrings pass. This branch is still based directly on protected main@5913c4bad... and the current tree does not contain tests/test_postgres_recovery_evidence_registry.py, while root prerequisite #233 (01d231fde...) supplies that missing stale-registry coverage and is the earliest serialized protected-integration prerequisite.
Treat this as a wrong-base/stack repair, not a reason to weaken --cov-fail-under=100, copy the predecessor test, close the PR, or create a no-op rerun. Preserve this PR's eight-file retirement delta and reconcile it ordinary/non-force through #233 (or a verified successor carrying #233 completely), then reacquire exact-final-head CI/Release/Security/SAST/CodeQL/review evidence. Because the branch has had a concurrent current-head update during this run, I am not moving the ref from this lane.
Preserve the exact eight-file extension-retirement delta while inheriting #233's recovery-registry coverage evidence as ancestry. This is an ordinary two-parent reconciliation: no copied test, coverage weakening, history rewrite, or force update.

Fail-closed legacy extension retirement — serialized stack authority
Current exact head is
e90e0f0a9d0c3e1c0150f0d2276523c809d79707. This lane remains stacked on #233 exact01d231fde23b82e2ced258d7bfcb4721ed75706d(fix/recovery-evidence-weakref-coverage-b84f0c9) rather than directly on protectedmain@5913c4bad79d6bc29d7cc1c624abb7db2ea6a77c.The existing retirement contract is preserved: retire the exact historical provider cron/helpers first, refuse unrelated cron authority and explicit extension dependencies, preserve application evidence, and use only
DROP EXTENSION ... RESTRICTinside one bounded transaction.Current causal repair: extension-owned schema preservation
Fresh source review found a destructive edge in the retirement preflight. The migration guarded unexpected table-like extension members and
DEPENDS ON EXTENSION, but did not guard a schema that had been enrolled as an extension member. PostgreSQL 18 explicitly permitsALTER EXTENSION ... ADD SCHEMA; an added object becomes an extension member, andDROP EXTENSIONremoves member objects even underRESTRICT. Therefore an accidentally enrolled application schema is not protected merely by spelling the final drop asRESTRICT.Test-first commit
9118c1c3fe3fb700fa4421bf786ac51e794bac2apins the missing static contract. Production commit394820df87d3b5d3de8470ca823468194392f6e4adds an explicitpg_namespacemembership preflight: everyhttpschema member and everypg_cronschema member other than the expectedcronschema fails closed before either extension can be dropped. Commite90e0f0a9d0c3e1c0150f0d2276523c809d79707extends the already-hosted live PostgreSQL cleanup smoke with a realCREATE SCHEMA+ALTER EXTENSION http ADD SCHEMAspecimen, requires retirement to fail, proves the schema and both extensions survive, then explicitly detaches/drops the fixture before continuing to the success/idempotency path.The repair does not authorize

It closes the schema-member deletion hole while retaining the accidental-table and explicit-routine-dependency specimens.

This lane still owns only its legacy-retirement surfaces:

Image/package/preload removal remains the later #103 stage after existing-volume retirement is proven; this PR does not broaden into
docker/postgres/Dockerfilewhile that compatibility boundary is live. Fresh descendant census finds no open PR based on this branch, so no restack is required.Exact-current acceptance

All currently listed inline review threads are resolved.
