0. Status and non-authorization

STATUS: PASS — engineering / design-only. Computes the aggregate preflight verdict from PF-1…PF-9. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Roll the preflight checks into a single, honest go/no-go.

2. Sources / evidence read

Preflight checklist (41) + checks (42–49); staging build gate (Macro-4 D57); entry gate v2 (D55). Main process, no reader-agents.

3. Accepted baseline (carried)

A build is eligible only if every preflight check passes and an Owner authority-PASS exists.

4. Evidence / analysis — aggregate preflight

Check	Verdict
PF-1 source snapshot	obligation defined (not run)
PF-2 runtime snapshot	obligation defined (FRESH baseline captured read-only)
PF-3 production counts	obligation defined (FRESH baseline captured read-only)
PF-4 forbidden surfaces	listed
PF-5 Owner build-approval	No-Go (absent)
PF-6 channel (GATE-4)	No-Go
PF-7 S2 owner (GATE-5)	No-Go
PF-8 Điều 0-G (GATE-3)	No-Go
PF-9 final	NO-GO

5. Candidate / requirement / gate / result

Aggregate preflight: NO-GO. Four hard checks (PF-5/6/7/8) are No-Go; the build cannot start. This mirrors the SB gate (NO-GO) and the entry gate v2 (NO-GO). No build is authorized.

6. Owner-gated future work

Clearing PF-5/6/7/8 is a set of Owner acts; forbidden now.

7. What remains unresolved

PF-5/6/7/8 No-Go; aggregate NO-GO.

8. Ready for GPT/Codex review

Yes — Codex should confirm the aggregate is honestly NO-GO.
