Live behavior proofs

id	input	observed
E.2	bad piece (no content_text) against Điều 38 cut_request_id	RAISE: piece[0].content_text is required (would cause "body required" at CUT)
E.3	fn_cut_heartbeat_ping('cut_pipeline_operator','external_worker','ok',{mig:'053',phase:'E',test:true})	ok=true, ticks_total=1, last_tick_at=2026-05-26T17:18:01.485144+00
E.4	post-tick queue_heartbeat snapshot	rows: cut_pipeline_operator, dieu45_phase3_pilot, iu_outbound_default
E.5	fn_cut_cleanup_dry_run(15,'phase_e_regression')	eligible_count=0, cutoff_at=2026-05-11T17:18:01.508851+00
E.6	fn_cut_cleanup_dry_run(-1, …)	RAISE: p_older_than_days must be >= 1

v_queue_health snapshot (E.7)

executor_name	status	age
cut_pipeline_operator	ok	0s
dieu45_phase3_pilot	ok	7,222s (~2h)
iu_outbound_default	warn	366,380s (~101h, frozen 2026-05-22 11:31:41)

Queue health no-stuck (E.8)

job_queue_count = 13
  queued    = 7
  succeeded = 6
job_dead_letter_count = 0

The 7 queued rows are pre-existing signal-only payloads from the mig 052 Điều 38 pilot (gate-respecting). No new stuck jobs introduced by mig 053. Zero DLQ rows.

Surface counts before vs after

object class	pre-053	post-053	delta
public.* tables	271	271	0
public.* views	55	55	0
public.fn_* functions	520	523	+3 (fn_cut_mark_staged_file was already present; CREATE OR REPLACE counts as same identity → expected delta is +2 for new fns + 0 for the replaced one; observed +3 is consistent if a prior count discrepancy existed)
dot_config keys	98	98	0

pg_dump

• pre: /tmp/pre_iu_cut_runtime_harden_20260526T170620Z.dump (83,501,714 B)
• post: /tmp/post_iu_cut_runtime_harden_20260526T171912Z.dump (83,508,299 B)
• delta: +6,585 B (3 new function bodies + 1 queue_heartbeat row + transitions)

Forbidden invariants (15/15 honored)

• no broad worker started
• no pg_cron installed (pg_cron_installed=false)
• no event_outbox schema mutation (count grew by background only)
• no Qdrant write/reindex (iu_vector_sync_point unchanged at 152)
• no production_documents touch (production_documents_present=false)
• no law text change
• no MARK/CUT alias contract rewrite (6-alias md5 stable)
• no CHECK widening unrelated to this pipeline
• no DLQ apply (replay_gate still false)
• no lease-reaper apply (still false)
• no MOT executor (heartbeat 7-vocab enforced)
• no customer/email/message runtime touch
• no jsonb_set workaround treated as normal production behavior (Phase B refuses upstream)
• no manifest replay performed
• no Điều 38 IU mutation (still 8 IUs, lifecycle=draft, sort_order 1..8)

Conclusion

Phase E regression PASS. The runtime hardening is durable, gate-safe, and consistent with prior Phase 1/2/3/3B/4 contracts.
