0. Status and non-authorization
STATUS: PASS — engineering / design-only. Confirms B2's IO contract instantiates every envelope field. Engineering PASS ≠ authority PASS. Default: HOLD.
1. Purpose
Verify that B2's contract (Deliverables 29–35) covers the full envelope (Deliverable 19) with no gap.
2. Sources / evidence read
Deliverables 19, 29–35; inspect-producer §4 (13-field template); TD-readiness §6 (IO-contract readiness). Main process, no reader-agents.
3. Accepted baseline (carried)
A complete contract is a precondition (F-1 frozen) for TD; a missing field makes TD unverifiable.
4. Evidence / analysis — completeness matrix
| Envelope field | B2 deliverable | Complete? |
|---|---|---|
| input_surface | 29 | yes |
| output_surface (candidate-only) | 30 | yes |
| error_surface | 31 | yes |
| evidence_surface | 32 | yes |
| rollback_surface / delete_fast_unit | 33 | yes |
| owner_surface / authority_gate | 34 | yes |
| forbidden_surfaces / production firewall | 35 | yes |
| promotion_surface | 27 (envelope) + 18 (forbidden register) | yes (forbidden now) |
| contract_id / version | 19/20 | shape only |
| no_production_touch_proof | 43–48 | yes (obligation) |
| bad_input_reject_rule | 49–53 | yes |
5. Contract / requirement / matrix / result
B2's contract is complete in shape (F-1 frozen). Two fields remain Partial/open by design: source-authority (Điều 0-G, 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 (B3/B4 runtime re-confirm) Partial; G-3 (Điều 0-G authority) No-Go.
8. Ready for GPT/Codex review
Yes — Codex should confirm no envelope field is missing from B2's contract.
