---

0. Status and non-authorization

STATUS: PASS — engineering / design-only. Confirms the refined B2 contract still instantiates every envelope field. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Verify the Macro-5 refinements (33–39) cover the full envelope with no gap.

2. Sources / evidence read

Macro-4 B2 contract completeness checklist (D36); refinements (33–39); standard IO envelope (D19). Main process, no reader-agents.

3. Accepted baseline (carried)

A complete contract (F-1 frozen) is a precondition for TD; a missing field makes TD unverifiable.

4. Evidence / analysis — completeness matrix

Envelope field	Macro-5 refinement	Complete?
input_surface	33	yes
output_surface (candidate-only)	34	yes
error_surface	35	yes
evidence_surface	36	yes
rollback/delete_fast_unit	37	yes
owner_surface/authority_gate	38	yes
forbidden_surfaces/firewall	39	yes
promotion_surface	31 (blocker) + 32	yes (forbidden now)
no_production_touch_proof	66–71	yes (obligation)
bad_input_reject_rule	72–77	yes

5. Candidate / requirement / gate / result

B2's refined contract is complete in shape (F-1 frozen, carried). Two fields stay Partial/open by design: Điều 0-G source authority (G-3 No-Go) and runtime B3/B4 re-confirmation (G-2 Partial). No field is bound to runtime here.

6. Owner-gated future work

Freezing and binding the full contract for TD is Owner-gated; forbidden now.

7. What remains unresolved

G-2 Partial; G-3 No-Go.

8. Ready for GPT/Codex review

Yes — Codex should confirm no envelope field is missing from the refined B2 contract.
