Gate 1 — Artifact verification (PASS)

Re-read both approved artifacts from KB and verified function artifact (rev3) content:

Check	Required	Observed	Result
Contains CREATE FUNCTION public.fn_birth_onboarding_full_scan()	YES	YES	PASS
Contains CREATE OR REPLACE	NO	NO	PASS
Contains COMMENT ON	NO	NO	PASS
Contains CREATE EXTENSION	NO	NO	PASS
Contains INSERT INTO directus_flows	NO	NO	PASS
Contains directus_operations DML	NO	NO	PASS
Contains cron.schedule	NO	NO	PASS

Rollback artifact (rev2) re-read: scope is DROP FUNCTION IF EXISTS public.fn_birth_onboarding_full_scan() plus negative-assertion guards for helper / gate / sibling policy. No Directus Flow/Operation DML — confirms Issue 4 fix scope.

Gate 2 — Preflight conflict check (PASS)

SELECT count(*) FROM pg_proc p JOIN pg_namespace n ON n.oid=p.pronamespace
WHERE n.nspname='public' AND p.proname='fn_birth_onboarding_full_scan';

Observed: conflict_count = 0 → PASS (function absent prior to execution).

Gate 3 — Preflight dependency check (PASS)

Dependency	Required	Observed	Result
fn_b3f1_log_collection_onboarding_gap(text,text,text,text)	exists	helper_count=1	PASS
fn_collection_onboarding_soft_gate() returns trigger	exists	gate_count=1	PASS
dot_config['policy.birth_trigger.accepted_sibling_scope'] row count	exactly 1	policy_key_count=1	PASS
Policy value parses as JSONB with entries array	yes	entries_len=1	PASS
fn_birth_registry_auto() resolves zero-arg trigger	exists	contract_count=1	PASS

Guarded DO block successfully parsed policy JSON (no POLICY_EMPTY, no POLICY_MALFORMED_JSON, no POLICY_ENTRIES_NOT_ARRAY raised).

Gate 4 — Advisory lock + in-transaction execution (PASS)

BEGIN;
SELECT pg_try_advisory_xact_lock(hashtext('p3d_birth_b3f1c_b_full_scan_function_execution')) AS lock_acquired;
-- lock_acquired = true
CREATE FUNCTION public.fn_birth_onboarding_full_scan() ...  -- exact reviewed SQL from artifact rev3
-- (in-transaction verification — see Gate 5)
COMMIT;

psql output:

BEGIN
LOCK_ACQUIRED=true
CREATE FUNCTION
COMMIT

Single transaction. Advisory lock acquired (no concurrent DDL conflict). Exact reviewed CREATE FUNCTION SQL executed verbatim — no modification, no CREATE OR REPLACE, no COMMENT ON, no extension creation, no DML, no smoke test invocation.

Gate 5 — In-transaction verification (PASS)

Query (run inside transaction before COMMIT):

SELECT p.proname, p.pronargs,
       pg_catalog.format_type(p.prorettype, NULL) AS return_type,
       l.lanname AS language, p.prosecdef AS security_definer,
       array_to_string(p.proconfig, ', ') AS config
FROM pg_proc p
JOIN pg_namespace n ON n.oid=p.pronamespace
JOIN pg_language l ON l.oid=p.prolang
WHERE n.nspname='public' AND p.proname='fn_birth_onboarding_full_scan';

Result:

Column	Required	Observed	Result
proname	fn_birth_onboarding_full_scan	fn_birth_onboarding_full_scan	PASS
pronargs	0	0	PASS
return_type	jsonb	jsonb	PASS
language	plpgsql	plpgsql	PASS
security_definer	t	t	PASS
config	contains search_path=public, pg_catalog	search_path=public, pg_catalog	PASS

All in-transaction checks PASS → COMMIT issued.

Gate 6 — Post-commit verification (PASS)

Same query, re-run outside transaction after COMMIT:

            proname            | pronargs | return_type | language | security_definer |             config
-------------------------------+----------+-------------+----------+------------------+--------------------------------
 fn_birth_onboarding_full_scan |        0 | jsonb       | plpgsql  | t                | search_path=public, pg_catalog
(1 row)

Identical to in-transaction verification. Function is durably installed.

Rollback SQL documentation (not executed)

Reviewed rollback from artifact p3d-birth-system-b3f1c-full-scan-rollback.sql.md (rev2). Recorded for manual use only if needed; NOT executed in this run.

-- B3-F1c-b rollback. COMPILE-ONLY artifact. Execute only on explicit reviewer instruction.
-- Scope: function-only. No Directus Flow/Operation DML (Issue 4 fix).
BEGIN;

-- 1. Drop the full-scan function. IF EXISTS so rollback is idempotent.
DROP FUNCTION IF EXISTS public.fn_birth_onboarding_full_scan();

-- 2. Negative assertion guard: refuse to commit if any B3-F1b object was collaterally affected.

What was explicitly NOT done

• No SELECT public.fn_birth_onboarding_full_scan() invocation (no DML smoke test).
• No INSERT / UPDATE / DELETE on any table.
• No system_issues writes.
• No system_health_checks writes.
• No DROP, ALTER, COMMENT ON, CREATE OR REPLACE, CREATE EXTENSION.
• No Directus Flow row created.
• No Directus Operation row created.
• No Nuxt endpoint created.
• No scheduler / cron binding.
• No cadence configuration.
• No hard gate.
• No Phase 5C2.
• No UI cutover.
• No git add / git commit / git push.

Live evidence summary

• Function public.fn_birth_onboarding_full_scan() returns jsonb is durably present in PostgreSQL after COMMIT.
• SECURITY DEFINER set with search_path=public, pg_catalog.
• B3-F1b helper, gate, and sibling policy untouched (function-only scope honored).
• Advisory lock hashtext('p3d_birth_b3f1c_b_full_scan_function_execution') was successfully acquired in-transaction; no concurrent DDL collision.

Next recommended action

GPT_REVIEW_B3F1C_B_EXECUTION_THEN_B3F1C_C_SCHEDULER_DESIGN

After GPT signs off on this execution report, proceed to B3-F1c-c (scheduler binding design — Directus Flow / cadence) under its own approval cycle. No invocation, scheduler, or Flow until that next review approves it.
