Verdict

Status: APPROVED_FOR_B3F1C_B_FUNCTION_EXECUTION_PROMPT_DRAFT

The revised B3-F1c full-scan function artifact is accepted for B3-F1c-b function-only execution prompt drafting. Execution is not directly approved by this review; Opus must draft a B3-F1c-b execution prompt and GPT must review it before Agent executes.

Accepted fixes

1. Schema-locked pg_class lookup

Accepted. The trigger-evaluation and birth_registry recursive-risk catalog lookups now constrain relation resolution directly with:

c.relnamespace = 'public'::regnamespace

This removes the prior relname-only lookup risk and prevents trigger detection from accidentally joining to same-name relations in non-public schemas.

2. Safe JSON policy parsing

Accepted. The sibling policy is now read as raw text, parsed inside a guarded block, and malformed JSON becomes structured dependency failure rather than an uncaught exception:

SIBLING_POLICY_MALFORMED_JSON
status='dependency_fail'

3. Duplicate policy key hardening

Accepted. The function now counts rows for policy.birth_trigger.accepted_sibling_scope before parsing:

• 0 rows → SIBLING_POLICY_MISSING

• 1 rows → SIBLING_POLICY_DUPLICATE_KEY

• 1 row → parse

4. Previous six blockers remain fixed

Accepted:

• COMMENT ON FUNCTION removed.
• dependency-failure pre-check exists before collection scan.
• public schema declared as reviewed deployment target, not schema-agnostic runtime discovery.
• rollback remains function-only.
• scheduler binding remains split to future phase.
• observability remains deferred to future scheduler design.

No-hardcode / self-expanding assessment

The artifact is acceptable under the no-hardcode principle because:

• sibling scope is read from dot_config, not embedded as a collection list;
• OIDs are resolved live, not hardcoded;
• snapshot counts are not used as gates;
• relation lookup is schema-qualified to the reviewed deployment schema;
• public is explicitly declared as a reviewed deployment constant, not hidden runtime hardcode;
• scheduler binding and cadence remain future policy/config decisions, not embedded here.

Important caveat

B3-F1c-b should install only the PG full-scan function. It must not create Directus Flow, Nuxt endpoint, scheduler rows, cadence config, or run the function as a DML smoke test.

Scheduler automation remains a separate future phase:

• B3-F1c-c or B3-F1d: Nuxt endpoint + Directus Flow binding + cadence policy + durable observability.

B3-F is still not COMPLETE until the full-scan function is installed and automatic scheduling/observability are designed, executed, and reviewed.

Required next step

Opus should draft B3-F1c-b function-only execution prompt.
