Opus Review — Agent Read-Only Investigation IU Current Position — For GPT Approval

Date: 2026-05-14 Reviewer: Opus (Claude Web) Report reviewed: knowledge/dev/laws/dieu44-trien-khai/reports/agent-readonly-investigation-iu-current-position-before-next-design-2026-05-14.md

Verdict: ACCEPT — Agent report quality excellent. One self-correction acknowledged.

---

1. Agent scope honored

Agent stayed strictly read-only: only SELECT queries on PG, only GET on Qdrant, only KB reads + 1 KB write (this report). No mutation at any level. Evidence tables in report demonstrate discipline.

2. All required checks covered

Check area	Covered	Quality
A. Birth completion live	✅	All Rev3 invariants I-1..I-7 verified with counts
B. IU core tables/functions	✅	11 functions verified by signature, gateway mode confirmed
C. Birth trigger / F6 / Pack 2B	✅	DOT-119 md5 match, trigger definition exact, pilot row found
D. TAC / DIEU-35 / fn_iu_create	✅	3 publications, 36 members, 86 units confirmed
E. Vector / search	✅	Qdrant green, sync_status=warning is known-informational
Opus supplementary 1a: description_policy	✅	0 NULL, distribution by tier reported
Opus supplementary 1b: DOT-119 md5	✅	Exact match confirmed
Opus supplementary 1c: identity_profile placement	✅	On information_unit YES, on birth_registry NO

3. Self-correction: Pack 2B P1 execution

Tôi (Opus) đã sai ở cross-check trước đó khi nói pack2b_allowed=true (design exists, needs revalidation post-birth, but no GPT execution gate opened yet) — ngụ ý Pack 2B chưa chạy.

Agent phát hiện đúng: Pack 2B P1 ĐÃ execute ngày 2026-05-05, pilot row pilot.iu0.test-001 vẫn live, Opus review P1 PASS, GPT directed keep. Chỉ thiếu formal closure doc.

Lý do tôi sai: Tôi dựa vào conversation_search/KB search mà không tìm thấy "Pack 2B closure" document. Agent có live PG access nên phát hiện pilot row + P1 report tồn tại.

Bài học: Không tìm thấy closure doc ≠ không đã thực hiện. Live evidence > KB search gap.

4. Agreement on key conclusions

Conclusion	Agree?
Birth System COMPLETE live confirmed	✅ Đồng ý — live evidence mạnh hơn cả KB docs
Phase 5C2 resume allowed	✅ Đồng ý
Phase 5C2 execution still gated	✅ Đồng ý — cần resume plan review trước
rev4 revalidation required	✅ Đồng ý — rev4 predates Birth Rev3 + Pack 23 require_review
parallel_design_tracks=no	✅ Đồng ý — Pack 2B P1 đã PASS, Pack 22/23 superseded remaining P2B scope
vector_efficiency_alert=NONE	✅ Đồng ý — sync_status=warning is known-informational
Next task = Phase 5C2 Resume Plan v1 (design-only)	✅ Đồng ý

5. Conflicts flagged — all valid

Agent flagged 6 conflicts/stale assumptions. All 6 are accurate and well-documented with evidence paths. No missing conflicts detected.

6. Recommendation for GPT

Accept Agent report. Proceed to dispatch Phase 5C2 Resume Plan v1 design task.

Suggested scope for Phase 5C2-R0 (read-only mapping/dry-run):

1. Recover 5C2 context from rev3/rev4/addendum — treat as reference, not executable
2. Map TAC 86 units → IU native schema using fn_iu_create canonical writer
3. Identify what rev4 assumed vs what's true now (Birth Rev3, Pack 23 policy, 12 pilot rows)
4. Define dry-run: generate SQL mapping WITHOUT executing
5. Define rollback strategy
6. Define validation criteria (0 drift between TAC render and IU render)
7. Hard boundaries: no bulk migration, no UI cutover, no schema mutation, no trigger changes

Agent type: Claude Code CLI xhigh (needs live PG + code access for mapping verification)

Deliverables:

• design/p3d-phase5c2-resume-tac-to-information-unit-migration-plan.md
• reports/p3d-phase5c2-resume-plan-report.md
