0. Status and non-authorization

STATUS: PASS — engineering / design-only. The master list of proof a future build must capture before it starts. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Answer macro question 4 (preflight half) — what proof is required before a future build?

2. Sources / evidence read

Macro-4 no-production-touch master proof plan (D43); entry gate v2 (D55); FRESH 2026-06-19 read-only checks. Main process, no reader-agents.

3. Accepted baseline (carried)

A build may begin only after an Owner authority-PASS and a captured baseline; the baseline is the FRESH read-only snapshot.

4. Evidence / analysis — preflight checklist (PF)

#	Preflight check	Deliverable
PF-1	source snapshot captured	42
PF-2	runtime snapshot captured	43
PF-3	production counts captured (must be unchanged)	44
PF-4	forbidden surfaces listed	45
PF-5	Owner build-approval present	46
PF-6	channel check (GATE-4)	47
PF-7	S2 owner check (GATE-5)	48
PF-8	Điều 0-G check (GATE-3)	49
PF-9	final go/no-go computed	50

5. Candidate / requirement / gate / result

All nine are obligations; none is run here. PF-5/6/7/8 are currently No-Go/absent, so the preflight cannot pass today. The checklist is the shape of a future proof, not a proof.

6. Owner-gated future work

Running the preflight is part of a build; Owner-gated; forbidden now.

7. What remains unresolved

PF-5/6/7/8 unsatisfied; preflight cannot pass.

8. Ready for GPT/Codex review

Yes — Codex should confirm the checklist is an obligation set, not an executed proof.
