Check	Result
SSH contabo reachable	OK
docker exec postgres reachable	OK
psql workflow_admin@directus opens	OK
SELECT version()	PostgreSQL 16.13 (Debian 16.13-1.pgdg13+1) on x86_64-pc-linux-gnu, compiled by gcc (Debian 14.2.0-19) 14.2.0, 64-bit
DDL/DML BEGIN; CREATE TABLE _gate0_probe…; ROLLBACK;	PASS; to_regclass('_gate0_probe') IS NULL = true
pg_dump -Fc to container /tmp/	OK (82,970,890 B)
Phase 1 tables present	OK — job_queue, job_dead_letter, queue_heartbeat
Phase 1 views present	OK — v_queue_health, v_job_queue_backlog, v_job_dead_letter_summary
Phase 1 functions present	OK — fn_job_ack, fn_job_claim, fn_job_enqueue, 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
Phase 1 queue.* dot_config keys	8 keys present (substrate/worker/notify/heartbeat = false; lease/retry tuning intact)

Verdict: HARD GATE 0 PASS.

Baseline row counts (pre Phase 2)

Silent-gap measurement

• iu_route_worker_cursor.iu_outbound_default.last_run_at = 2026-05-22 11:31:41.928657+00
• silent_seconds at baseline = 346,163 s ≈ 96.2 hours
• Pre-Phase 2, this gap is NOT surfaced in v_queue_health or fn_queue_stale_check (queue_heartbeat empty).

Extensions

SELECT extname, extversion FROM pg_extension:

• btree_gist 1.7
• pgcrypto 1.3
• plpgsql 1.0
• postgres_fdw 1.1

pg_cron NOT installed. Phase 2 does NOT install it.
