Summary

Validates migration history objects for Phase 6.2 database reconciliation:

  • Validates the three document foreign keys added across history (storage_cleanup_jobs_document_id_fkey, rag_visual_eval_cases_document_id_fkey, rag_visual_eval_runs_document_id_fkey) referencing public.documents(id) with ON DELETE SET NULL.
  • Validates retention comments and pg_cron scheduled purge jobs.
  • Adds regression unit test coverage in tests/migration-history-guards.test.ts.

Verification

  • npm run test -- tests/migration-history-guards.test.ts (8 passed)
  • npm run verify:pr-local

Risk and rollout

  • Risk: validation-only migrations and contract tests; no destructive schema alterations.
  • Rollback: Revert commit cleanly via git revert with no schema teardown needed.
  • Provider or production effects: None
  • RAG impact: no retrieval behaviour change

Clinical Governance Preflight

  • Source-backed claims still require linked source verification before clinical use
  • No patient-identifiable document workflow was introduced or expanded without explicit governance approval
  • Supabase target remains Clinical KB Database (sjrfecxgysukkwxsowpy)
  • Service-role keys and private document access remain server-only
  • Demo/synthetic content remains clearly separated from real clinical sources
  • Source metadata, review status, and outdated/unknown-source behavior remain conservative
  • Deployment classification/TGA SaMD impact was checked when clinical decision-support behavior changed

…o-statements history rows

Six fail-fast validation guard migrations (20260804110240 pattern) covering every
object the fifteen hand-applied/mark-applied July versions left on live, and the
fifteen migration_history allowlist entries that point at them (class validation,
never bare). Guards validate only: absences, catalog comments + retention cron,
document FKs, 46 operational index shapes, the index_generation_id promotion,
and 15 function def_hashes read from schema_drift_snapshot() itself.

Proven: full chain replay into the scratch image Applied 210/210 and
CHAIN == MANIFEST (zero unexpected drift); seven mutation proofs raise and name
their object; all six dry-ran green on production and a mutant fails there;
applied to production by real db push (rows carry statements) and to staging by
the Phase 2 method (md5-matched); staging drift comparison green.

tests/migration-history-guards.test.ts: the create-index check now ignores string
literals/comments (the reference pattern pins canonical `create index` text as
data) and requires set local statement_timeout; 20260804110240 is pinned as
satisfying the predicate.

Ledger: #Q5JHBJ (#316 umbrella). RAG impact: no retrieval behaviour change.

How do review limits work?

CodeRabbit enforces per-developer PR review limits within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

📝 Walkthrough

Walkthrough

The change tightens cron and foreign-key validation, improves detection of dynamic SQL in migration guard tests, adds regression coverage, and records Phase 6.2 verification outcomes.

Changes

Migration-history validation

Layer / File(s) Summary
Cron and foreign-key validation guards
supabase/migrations/20260819110100_validate_history_comments_and_retention.sql, supabase/migrations/20260819110200_validate_history_document_foreign_keys.sql
Cron checks now validate schedule and purge command. Foreign-key checks now require references to public.documents.id. The SQL comment contains unresolved merge-conflict markers.
Dynamic SQL scanning and regression coverage
tests/migration-history-guards.test.ts
The scanner exposes SQL inside dynamic EXECUTE statements while preserving ordinary literal masking. Tests cover quoting, format(), concatenation, and dynamic index creation.
Phase 6.2 verification record
docs/branch-review-records/6a3785a84afec6df46b90f552bb0b3bcb3555d1c1b80156ecbf1c4ce17a2d357.record.md
The record documents drift validation, replay checks, environment verification, dry-run and mutant results, and a queued P2 alignment-step failure.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔴 Critical · up to 65c58

The PR currently contains migration conflict markers that can prevent the validation migration from running, and its history checks can accept invalid index, retention, or foreign-key definitions. It is not merge-ready until these correctness and migration-safety issues are fixed.

Remove the obsolete Phase 4 programme update.

This paragraph duplicates its heading. It also states that the fifteen migration_history rows remain and that #Q5JHBJ needs dispatch.

That conflicts with Line 94 and Line 131, which state that Phase 6.2 is complete. Keeping both instructions can send the coordinator to a completed task.

76-78: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Validate the full retention command.

Lines 76-78 use substring checks. A command ending with interval '90 days' OR true passes and deletes all retrieval logs.

Normalize and compare the complete expected command. This must reject changed predicates and added statements. The supplied guard-migration contract requires a normalized canonical definition.
