0. Status and non-authorization

STATUS: PASS — engineering / design-only. The postflight proof that no candidate was promoted to production. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Define the after-build proof that the promotion firewall held (no staging→production flow).

2. Sources / evidence read

Macro-4 no-production-touch promotion firewall (D48); promotion-blocker candidate (31); production counts unchanged (52). Main process, no reader-agents.

3. Accepted baseline (carried)

Promotion is default-blocked; a validated candidate is evidence, not a production write; promotion needs a separate Owner gate.

4. Evidence / analysis — no-promotion proof obligation

Proof	Postflight must show
no candidate inspect_* copied to production birth_registry	confirmed (counts unchanged)
no certified=true derived from a candidate	confirmed (1,402 frozen)
no canonical/owner write from a candidate	confirmed (0 unchanged)
promotion-state = blocked on every candidate	confirmed

5. Candidate / requirement / gate / result

A build passes PT-4 only if every candidate stayed on the disposable surface and nothing crossed the firewall. No promotion is possible here (no build, no candidate). Obligation defined; no proof run.

6. Owner-gated future work

Opening the promotion gate is an Owner act; forbidden now.

7. What remains unresolved

No build; no promotion proof exists.

8. Ready for GPT/Codex review

Yes — Codex should confirm promotion stays default-blocked and the proof is obligation-only.
