Doc 05 — Branch F: 4 Mothers Gate Decision

4 Mothers implementation remains BLOCKED. This doc states exactly what blocks it, what can run in parallel, and the next-macro sequence. No 4 Mothers implementation performed.

---

1. Blockers that MUST close before 4 Mothers implementation

#	Blocker	Why it gates 4 Mothers	Carrier
B1	Production review_decision path	Every Mother output is a governed object; without a real Đ32 approval path, Mothers would either bypass review or be stuck on the test builder	Branch C / macro 2
B2	Candidate Registry Survey not done	4 Mothers = industrial object factories (Rev5 MP-D24/25); they need the candidate/tier registries to know what they may produce and under which governance	macro 4
B3	Human-org-role / permission law gap	Đ37 governance registry has no human roles (Rev5 cross-law finding D-1). MOW UI assigns work to humans/departments → needs the human-org-role + permission law layer (Directus role + field allowlist + Đ32 today; a future human-org-role law flagged)	future law macro (not yet scheduled)
B4	P-pub at least at block_new	Mother-born IUs must carry publication authority to be lawful at scale (avoid "đẻ rơi"); warn-only is fine for pilot but not for factory births	Branch B / macro 1

2. Blockers that can run in PARALLEL (do not serialize)

• KG relationship enrichment (Branch D / macro 3) — independent of B1/B2; can proceed alongside Candidate Registry.
• Master Design reconciliation patch (macro 6) — documentation; parallel-safe.
• Limited pilot operating protocol (macro 5) — can start immediately; does not need any Mother.

3. Specific decisions requested by the macro

1. Should Candidate Registry Survey run now? → YES. It is the next substantive macro and a hard prerequisite (B2) for any Mother. It is document/survey-class (low risk) and unblocks MOT/MOIT/MOUT envelope design.
2. KG relationship macro before or after Candidate Registry? → In parallel, but Candidate Registry has priority of dependency. KG enrichment (macro 3) is not required to start Candidate Registry; run them concurrently. If forced to serialize, Candidate Registry first (it gates Mothers; KG enriches but does not gate the registry).
3. Does the human-org-role / permission law gap block MOW UI? → YES, MOW UI specifically. MOW assigns tasks to humans/departments; with no human roles in Đ37, assignment authority/permission is unspecified at the law layer. Backend MOW (workflow/task IU relations) can be designed, but the assignment/permission surface of MOW UI is blocked until the human-org-role + permission layer is settled (Directus-role interim per D-1, future law for durable form). MOT/MOIT/MOUT are less exposed to this gap.
4. Can the IU limited pilot start before 4 Mothers? → YES. The limited pilot operates IU Core directly (cut/reconstruct, b/c/f reads, governed d/e/f under protocol, DLQ, gates) and does not require any Mother. Branch A declares LIMITED-PRODUCTION-PILOT READY. The pilot can begin under the operating protocol (macro 5) immediately and in parallel with all 4-Mothers prerequisite work.

4. Recommended next-macro sequence

NOW (parallel):
  ├─ macro 5  IU_LIMITED_PRODUCTION_PILOT_OPERATING_PROTOCOL      (start pilot)
  ├─ macro 4  IU_CANDIDATE_REGISTRY_SURVEY_FOR_4MOTHERS           (B2, gates Mothers)
  ├─ macro 3  IU_KG_RELATIONSHIP_ENRICHMENT_READINESS_AND_PATCH   (parallel)
  └─ macro 6  MASTER_DESIGN_LIVE_INVENTORY_RECONCILIATION_PATCH   (doc truth)

THEN (governance hardening, order: vocab → fn_create → block_new → backfill → block_all):
  ├─ macro 2  IU_PRODUCTION_REVIEW_DECISION_GOVERNANCE_PATH       (B1)
  └─ macro 1  IU_PPUB_BIRTH_GATE_SAFE_PROMOTION_OR_STAGED_AUTHORITY (B4; block_all depends on macro 2)

THEN (new law work, not yet macro'd):
  └─ HUMAN_ORG_ROLE_AND_PERMISSION_LAW_READINESS                 (B3; unblocks MOW UI)

THEN:
  └─ 4 MOTHERS implementation (only after B1, B2, B4 closed; MOW UI also needs B3)

5. Bottom line

• 4 Mothers: BLOCKED on B1 (prod review_decision), B2 (Candidate Registry), B4 (P-pub block_new); MOW UI additionally on B3 (human-org-role/permission law).
• IU limited pilot: NOT blocked — can start now.
• Candidate Registry Survey: run now, in parallel with KG enrichment and pilot.
