§1. P11C là gì

P11C = Proof relation edges giữa các information_unit ("miếng") trong TAC pipeline.

Xuất phát từ P11A Gap B / Relation edges — cần model unit-to-unit relation (references, depends_on, contradicts, supersedes, implements, compatible_with...) trên 86 units / 3 publications hiện hữu (D28/D32/D35).

§2. Cover bởi

Tài liệu	Vai trò P11C
P44-4A dieu44-trien-khai/design/05-relation-edge-conformance-design.md	Logical contract edge entries (E1-E8, INV-E1..E8, vocab, audit chiều, anti-drift, sunset, reverse-index pattern)
P44-5A dieu44-trien-khai/design/06-update-mechanism-dot-contract-matrix.md	Realize logical contract: Update Mechanism + DOT Contract Matrix Cap-4/Cap-5
P38-XC dieu44-trien-khai/design/04-information-unit-profile-schema.md	Nền Information Unit + Capability matrix Cap-4/Cap-5
P11A dieu38-trien-khai/reports/p11a-information-unit-schema-inventory-2026-05-01.md	Inventory + Gap analysis xác định P11C scope

§3. Đã chốt (design phase DONE)

• universal_edges là SSOT cho relation + composition edges TAC.
• tac_publication_member chỉ là helper / enforcement / materialized representation — không phải SSOT.
• Cap-4 Relation + Cap-5 Composition với 8 Core + 3 Candidate edge types.
• INV-DUAL-1..4 anti-drift cho Dual transitional + sunset path 4 conditions / 2 exit paths.
• Reverse-index P1/P2/P3 decision framework (P1 pilot-only; threshold defer).
• Auto-fix vs escalate policy (autofix_enabled start-OFF; INV-DUAL-1/2 với 2 bộ 6 guard chặt).
• Role vs Procedure separation (Role = DOT recurring; Procedure = one-shot controlled).
• Edge checker không tự mutate Object lifecycle — cascade retire thuộc Đ4 lifecycle mechanism (2 layer separation).

§4. Chưa làm (execution phase)

• Chưa DDL / code / trigger.
• Chưa DOT thật trong dot_registry.
• Chưa execute audit (TD-44-2).
• Chưa retrofit ~2199 legacy edges (TD-44-3).
• Chưa benchmark reverse-index P1→P2→P3.
• Chưa pilot Tier 1 trên TAC family.
• Chưa populate relation edges thật giữa 86 units.

§5. Defer

Hạng mục	Defer đến
Implementation (DDL + code + DOT names + schedule + threshold + Authority Map alignment + birth gate enforcement code)	P44-6 — Implementation Realization
Pilot execute writer/checker/reverse-index + populate edges + benchmark	Pilot Tier 1 (sau Đ44 enacted v1.0 + APR cấp high)
Topic assembly proof (cross-publication topic view)	P11D — Topic View proof

§6. Kết luận

• P11C Design phase: ✅ CLOSED
• P11C Execution phase: ⏸ DEFERRED sang P44-6 + Pilot Tier 1
• Tier 4 unlock: ⏸ PENDING sau pilot pass + Đ44 Conformance Clause C5 verify
• Next recommended: P11D Topic View proof (theo P11A §5 Proof 3)
• P44-6 chưa mở ngay — chờ Đ44 enacted v1.0 + APR cấp high
