…enant RLS Migration 0013 declares an append-only guard and a tenant-scoped RLS policy on all five job-analysis tables, but the PostgreSQL contracts only proved them on the root job_analysis_snapshot table. A dropped guard or policy on job_analysis_task_item, job_analysis_ksao_item, job_analysis_task_ksao_link, or job_analysis_write_command would have passed both CI contracts silently. The unowned schema-hardening contract now proves, per child table: - UPDATE and DELETE are rejected by the append-only guard on a seeded row (the row-count precondition keeps the proof non-vacuous); - pg_class shows ENABLE+FORCE row-level security and exactly one permissive ALL policy whose USING and WITH CHECK both call current_tenant_record_id(); - a probe role under another tenant sees zero rows. The catalog assertions are required because a missing policy also returns zero rows, so the behavioral read alone cannot distinguish "isolated" from "denied". Verified locally on a clean cluster at develop eb9757f: - parent + hardening contracts PASS (test_job_analysis_snapshot_postgres.sh, then test_job_analysis_snapshot_schema_hardening.sh against one database, as CI runs them inside the same container); - non-vacuity: removing the task_item trigger fails as "job_analysis_task_item UPDATE was not rejected by the append-only guard: UPDATE 1"; removing the write_command RLS policy fails as "job_analysis_write_command must ENABLE and FORCE row-level security: false:false"; - npm run validate EXIT=0 (55 node tests).

- Around line 95-96: Harden the RLS policy validation query using polcmd,
polqual, and polwithcheck: require exactly one permissive policy and compare its
command and normalized USING/WITH CHECK expressions exactly, rather than
matching function names with LIKE. Extend the probe to attempt a valid
cross-tenant INSERT and verify it is rejected, not just validate the SELECT
path.

Migration
database/migrations/0013_job_analysis_snapshot.sqldeclares append-only guards and tenant-scoped RLS on the root Job Analysis snapshot plus all four child tables. The CI-wired PostgreSQL contracts originally exercised only the root table, so dropped child triggers or policies could pass silently.This PR remains test-only. It changes
tests/test_job_analysis_snapshot_schema_hardening.sh; no production migration, workflow, domain source, or sealed file is changed.Repair lineage

The CodeRabbit Major thread was verified against current migration/source, answered, and resolved; that acknowledgement is not an independent approval.A further evidence audit found a narrower false-green path in
683061...: predicate shape and negative probe behavior did not prove that the policy was actually applicable to the intended probe/runtime role. With RLS enabled, a policy scoped to an unrelated role can default-deny another role and make cross-tenant SELECT/INSERT appear isolated even though the expected PUBLIC tenant policy was not installed.f2f3585395239868f34e2cc28197442873974286is the minimal ordinary-forward repair:NOLOGIN NOSUPERUSER NOCREATEDB NOCREATEROLE NOREPLICATION NOBYPASSRLS;polcmd='*', with exact normalized tenantUSINGandWITH CHECKexpressions;polroles = ARRAY[0::oid], the catalog representation ofPUBLIC, matching migration 0013'sCREATE POLICY ...declarations without aTOclause;Exact-head authority
