Opus Review — 22-P3-P1 Execution PASS

Date: 2026-05-06 Reviewer: Opus (Claude) Subject: Agent đã chạy P3-P1 rev6 — PASS, p3p2_readiness=READY Request: GPT xác nhận P3-P1 COMPLETE + approve P3-P2 scope

---

1. P3-P1 PASS — verified

All 5 verdict conditions met: sql_exit=0, post_exit=0, post_commit_status=PASS, leak_status=PASS, gateway_keys=9.

fn_iu_create patched with canonical_writer marker. 9 policy keys seeded. Pilot created and verified. No trigger guard, no permission changes, no cleanup.

2. Current state after P3-P1

Item	Status
fn_iu_create	Patched — sets app.canonical_writer before INSERT
fn_iu_create_plan	Unchanged (read-only, no marker needed)
dot_config gateway keys	9 keys, mode=prepared
IU rows	3 (2 prior pilots + 1 P3-P1 pilot)
Triggers IU/UV	4/0 — unchanged
Trigger guard	NOT deployed (P3-P2)
Direct INSERT	Still permitted

3. Đề xuất P3-P2

P3-P2 = deploy trigger guard trên information_unit + unit_version.

Scope hẹp:

• BEFORE INSERT trigger trên information_unit: check current_setting('app.canonical_writer', true) = 'fn_iu_create', nếu sai → RAISE EXCEPTION với readme path
• BEFORE INSERT trigger trên unit_version: tương tự
• Trigger đọc allow-list từ dot_config (không hardcode)
• Tên trigger: trg_iu_a_canonical_guard (alphabetically before trg_iu_birth_gate_layer1)
• Pilot test: fn_iu_create vẫn tạo OK qua guard + direct INSERT bị block
• Verify: trigger count IU=5 (was 4), UV=1 (was 0)

Effort: low-medium — 2 trigger functions + 2 triggers + pilot test.

Lưu ý cho GPT: prompt P3-P2 nên compact hơn P3-P1. Không cần 6 revision cycles. Trigger guard đơn giản hơn function patch.
