Handoff S182 → S183 (updated mid-S183)

Phiên: S182→S183 | Ngày: 2026-04-27 Tóm tắt: P7 pilot + P8 OFFICIAL + P9 Entry Gate through E-R3 execution PASS.

1. Trạng thái cuối S183 (in-progress)

Phase	Status
P7 Pilot (P7A→P7B→C2A→PF-4→C2B→P7C)	✅ COMPLETE
P8 Implementation Design v0.3	✅ OFFICIAL
P9 Entry Gate Tier 1	✅ 4 blockers found
P9 Tier 2 Remediation Design v0.2	✅ GPT PASS
E1 fn_log_issue verify	✅ PASS
E2 Đ24 facet design	✅ DESIGN (FAC-07/08/09 candidate)
E3 entity_code contract	✅ DESIGN (D38 local)
R3 adapter design	✅ DESIGN (dedup contract)
E-R3 wrapper dry-run v0.2	✅ GPT PASS → OFFICIAL
E-R3 execution v0.4	✅ PASS — function created + verified

2. E-R3 Execution Summary (S183)

• What: Created public.fn_tac_log_checker_issue on production DB directus
• Prompt version: v0.4 (3 rounds GPT review, 14 patches total)
• Agent: Codex (GPT-5)
• Evidence: reports/p9-e-r3-execution-log-2026-04-27.md
• Key findings: evidence_snapshot type=json (dùng ::json cast), fn_log_issue param #9=p_run_id (not resolution), wrapper passes NULL
• Scope compliance: No system_issues write, no test INSERT, no E4/E7/P9

3. Việc tiếp (chưa làm)

#	Việc	Loại	Cần gì
1	E-E3: Amend P8 §5 (entity_code + Đ24 alias)	Doc only	GPT review
2	E4: APR request FAC-07/08/09	Governance mutate	APR flow
3	E5: Create 3 facets (nếu APR approved)	Taxonomy write	APR approved
4	E7: dot-dot-register v2 (D1–D3 dry-run → D4 register)	dot_tools write	Approval riêng
5	E6: Re-run Tier 1 A1–A4	Read-only	E1–E5 done

4. Operating model

User = mục tiêu/yes-no. Opus = điều hành. GPT = giám sát. Escalate khi: đụng production, rủi ro, governance lớn.

5. Bài học S183

• Prompt DDL production cần ≥3 rounds GPT review (v0.1→v0.4, 14 patches)
• Schema-qualify mọi object reference (CREATE/ALTER/DROP/internal refs)
• Runtime user assertion (DB_USER == workflow_admin) trước DDL
• Final SQL materialization + log trước execute (không sửa tay heredoc)
• fn_log_issue param naming: verify actual vs design doc, ghi chênh lệch
