S186 New Session Handoff Confirmation — 2026-04-28

Verdict

READY TO BEGIN COORDINATION, but NOT ready to dispatch Agent execution.

The next governed step is to ask Opus 4.6 to patch Trigger Guard DROP Repair Gate Option A+ v0.3 into v0.4, then GPT reviews v0.4. Agent dispatch is blocked until explicit User GO after review.

Confirmed state from Agent Data

1. G6 dry-run: PASS per prior P9/G6 repair records.
2. Gate A Production DDL: current intended production state is correct: 14 public.tac_* tables, new fn_tac_* functions/triggers exist; no seed, Directus collections, roles/permissions, Gate B/C/G8B/G11/P9 were authorized in Gate A scope.
3. Gate A incident: stale CHECK=115 and attempted rollback occurred; rollback was blocked by fn_evt_trigger_guard_drop() DROP bug; final production DDL state remained correct but incident required review.
4. Open blocker: repair public.fn_evt_trigger_guard_drop() DROP handling before Gate B/C/G8B/G11/P9 continuation.
5. Investigation result: r.object_name can be NULL on DROP TRIGGER; function also had unqualified trigger_guard_alerts and no controlled search_path.
6. Repair prompt v0.3 status: major executor-role issue fixed: mutation/smoke must use workflow_admin, not directus.
7. Required v0.4 patches before dispatch:
   • Header must say READY FOR USER GO, not AUTHORIZED.
   • Smoke audit row check must match exact generated trigger name, not LIKE '%drop_smoke%'.
   • All mutation/smoke psql invocations must use -v ON_ERROR_STOP=1 -X and capture exit/output.

Coordination rule for this session

Role chain: User => GPT => Opus 4.6 => Agent.

GPT role: direction, decision escalation, supervision, and critique. Any non-self-evident operational decision, scope expansion, production mutation, rollback, or gate progression requires User permission.

Hard blocks

Do not start Gate B, Gate C, G8B, G11, or P9 continuation until DROP guard repair has PASS review.

Do not dispatch Claude Code / Agent execution until Opus v0.4 is reviewed and User gives explicit GO.
