Phase 1 substrate intact

All Phase 1 objects still present and unchanged at definition level:

Tables: job_queue, job_dead_letter, queue_heartbeat Views: v_queue_health, v_job_queue_backlog, v_job_dead_letter_summary Functions (Phase 1): fn_job_enqueue, fn_job_claim, fn_job_ack, fn_job_fail_or_retry, fn_job_move_to_dead_letter, fn_job_queue_updated_at (trigger), fn_queue_heartbeat_tick, fn_queue_stale_check Triggers: 2 (fn_job_queue_updated_at on job_queue, queue_heartbeat updated_at trigger) Constraints: 8 unique CHECK constraints on Phase 1 tables (verified by name) — unchanged.

event_outbox unchanged

Check	Status
pg_constraint CHECK constraint names	9 — unchanged
event_outbox_safe_payload_check definition	unchanged (denylist mirrored to job_queue/job_dead_letter in Phase 1)
Row count delta	+1,019 background only
Rows with actor_ref matching %phase2%	0
Rows with canonical_address matching %phase2%	0
Latest created_at from background traffic	2026-05-26 13:30:18 (predates Phase 2 mig commit at 13:52)

iu_route_worker_cursor frozen

worker_name='iu_outbound_default':

• baseline last_run_at = 2026-05-22 11:31:41.928657+00
• post-Phase 2 last_run_at = 2026-05-22 11:31:41.928657+00
• Unchanged. Silent gap still ~96h+. (Phase 3 is responsible for restoring real worker activity OR explicitly retiring this row.)

pg_extensions

{btree_gist 1.7, pgcrypto 1.3, plpgsql 1.0, postgres_fdw 1.1} — unchanged. No pg_cron installed.

MARK/CUT alias surface unchanged

fn_iu_op_* 5 aliases present: fn_iu_op_cleanup_dry_run, fn_iu_op_cut, fn_iu_op_mark_file, fn_iu_op_verify_cut, fn_iu_op_verify_mark. None modified by Phase 2.

Gate states at exit

Gate	Pre Phase 2	Post Phase 2	Note
queue.job_substrate.enabled	false	false ✓	Worker substrate kept inert
queue.worker.enabled	false	false ✓	No worker started
queue.notify.enabled	false	false ✓	No NOTIFY emission
queue.heartbeat.enabled	false	true	Phase 2 governance armed (no daemon)
queue.lease.reaper_enabled	(absent)	false ✓	Default off
queue.lease.reaper_dry_run_only	(absent)	true ✓	Safety default
queue.dlq.replay_enabled	(absent)	false ✓	Default off
queue.runtime.phase	(absent)	phase2_governance	Marker

Forbidden list audit (15/15 honored)

1. No pg_cron install — confirmed
2. No worker/daemon/cron started — confirmed
3. No event_outbox traffic from Phase 2 — confirmed (0 rows)
4. No event_outbox schema change — confirmed (9 CHECKs intact)
5. No event_outbox row mutation — confirmed
6. No event_type_registry widening — confirmed (no DDL touched it)
7. No iu_sql_event_route CHECK widening — confirmed
8. No Qdrant touch — confirmed
9. No production_documents touch — confirmed (absent throughout)
10. No fn_iu_op_* MARK/CUT alias change — confirmed
11. No START-HERE change — confirmed (no file edits)
12. No Điều 45 law text change — confirmed
13. No customer/email/MOT runtime — confirmed
14. No queue.worker.enabled=true flip — confirmed (kept false durably)
15. No queue.job_substrate.enabled=true durable flip — confirmed (only inside rolled-back proof TX)

Verdict

Regression PASS. Phase 1 substrate intact, no worker started, no schema widening, no payload-key vocab widening, no MARK/CUT touch, no event_outbox schema mutation, all forbidden categories honored. Silent gap NOW visible via v_queue_health and fn_queue_stale_check — risk surface closure delivered as scoped.
