Opus Review — P3D Pack 1 Phase 5 Dry-Run PASS (Full Evidence)

Date: 2026-05-11 | Author: Opus 4.7 For: GPT + User — all evidence complete, 3 architectural decisions pending

---

1. Verdict: PASS — complete evidence, zero blockers

Rev6 registry disambiguation resolved all 3 AMBIGUOUS fields. All 11 goals returned evidence. Zero writes. Scale self-audit passed. Evidence gathering for Phase 5 is COMPLETE.

2. Evidence dashboard

Area	Key finding	Status
Source size	86 logical units, 86 versions, 3 publications	Confirmed
Per-publication	Đ35=36, Đ32=23, Đ28=27 (sum=86)	✅
Nesting	3 roots, depth max=2, 83 children	Confirmed
render_order	Contiguous [0, n-1] per pub, no duplicates	✅ PASS
Address collisions	0/86	✅ PASS
Hash divergence	5/5 TAC ≠ IU recipe (re-verified live)	Confirmed
Provenance carrier	content_profile (jsonb) exists, 0/19 populated	Available
Birth gate fields	All SATISFIED on information_unit	✅
Functions	6/6 PRESENT (fn_iu_create accepts p_parent_ref)	✅
PLAUSIBLE species	4 atom + 4 molecule (management_mode=observed)	None semantically "law"
Pilot metrics	Đ35: 12 types, depth 2 (most diverse)	candidate_not_approved

3. Three decisions for GPT/User

Decision 1: Nesting (D1/D2/D3)

Evidence: depth=2 (shallow), 83/86 children, render_order contiguous per publication, fn_iu_create accepts parent_ref, parent_or_container_ref column exists on IU.

Option	Consequence
D1 preserve	Parent IU rows contain children → not atom → need compound/molecule species
D2 flatten	All IU = atom → simpler species → loses structural FK but keeps render_order
D3 hybrid	Nesting as edges/metadata → atom composition → moderate complexity

Decision 2: Species/composition (follows from nesting)

If nesting	Composition	Species approach
D1	Mixed (parent=compound, leaf=atom)	New species or per-depth differentiation
D2	Uniform atom	Existing observed/atom species (e.g., governance_infra) or new
D3	Uniform atom	Same as D2

Phase 4D memo noted: no existing species semantically matches "law_unit." New species likely regardless of nesting choice.

Decision 3: Pilot document

Publication	Members	Section types	Depth	Label
Đ35	36	12	2	candidate_not_approved
Đ28	27	7	2	candidate_not_approved
Đ32	23	8	2	candidate_not_approved

Đ35 has most structural diversity (12 section_types). But all are candidate — GPT/User picks.

4. Handoff summary

Context này đã rất dài. Đề xuất lưu handoff vào KB để phiên mới tiếp tục:

COMPLETED:
- Phase 4 vocab: 14 keys committed, planner law_unit=plan_ok
- Phase 4B-4D: species/composition deferred to Phase 5 (Option 2)
- Phase 5 dry-run: FULL PASS — all evidence gathered, registry proven

PENDING DECISIONS (GPT/User):
1. Nesting: D1 (preserve) / D2 (flatten) / D3 (hybrid)
2. Species: new species likely; composition follows nesting
3. Pilot: Đ35 (most diverse) / Đ28 / Đ32

NEXT EXECUTABLE:
- Phase 5B: species_collection_map seed + QT-001 backfill
- Phase 5C: pilot migration (one publication)
- Phase 5D: full batch migration
