A1 — Taxonomy Facets

Check	Result	Status
FAC-07 exists, active	id=8, "Thuộc tài liệu nào?", active	✅ PASS
FAC-08 exists, active	id=9, "Chủ đề nội dung?", active	✅ PASS
FAC-09 exists, active	id=10, "Tầng kiến trúc?", active	✅ PASS
Total taxonomy facets = 10	7 baseline + 3 new	✅ PASS

A1 Verdict: PASS

A2 — Entity Code Contract

Check	Result	Status
D38-local contract documented	P8 v0.4 §5.2	✅ PASS
Regex defined	^D38-[A-Z0-9]+-((ROOT)|(S[0-9]+(-P[0-9]+(-[0-9]+)*)?))$	✅ PASS
76 pilot units match	P7A/C2B reports verified	✅ PASS (evidence-based)
Contract scope = D38-local only	Ghi rõ trong P8 §5.2	✅ PASS

A2 Verdict: PASS (evidence-based, cannot re-query sandbox_tac from web chat)

---

A3 — System Issues Adapter

Check	Result	Status
public.fn_tac_log_checker_issue exists	E-R3 execution log: created, verified	✅ PASS
Owner = workflow_admin	Confirmed in E-R3 log	✅ PASS
SECURITY DEFINER = true	Confirmed	✅ PASS
search_path = public, pg_catalog	Confirmed	✅ PASS
6 params correct	Confirmed	✅ PASS
Usable by registered DOTs	Function exists; DOTs must be registered (E7 ✅) and approved per Đ35 governance	✅ PASS

A3 Verdict: PASS (evidence from E-R3 execution log)

---

A4 — DOT Registration

Check	Result	Status
19 DOT-TAC-* exist	19 items returned	✅ PASS
All active	19/19 active	✅ PASS
7 B-tier paired_dot valid	7/7 reference existing A-tier codes	✅ PASS
12 A-tier paired_dot = null	12/12 null	✅ PASS
FK domains valid	All 19 domains in FK vocabulary	✅ PASS
No duplicates	19 unique codes	✅ PASS
Cross-check P8 §3.2	19/19 match P8 table (7B+12A)	✅ PASS

A4 Verdict: PASS

Observation: _dot_origin SUSPECT prefix

All 19 DOTs have _dot_origin = "SUSPECT:dot-dot-register|E7|S183". This is Directus hook behavior — auto-prefixes "SUSPECT:" to non-standard origins at INSERT time.

Assessment: Not a blocker. Metadata classification behavior, not data corruption. The intended origin dot-dot-register|E7|S183 is preserved after the prefix. Cleanup (removing SUSPECT: prefix) would require UPDATE mutation → needs its own gate if desired. Not patching during E6.
