0. Status and non-authorization

STATUS: PASS — engineering / design-only. The postflight check that source/law/report files are unpatched after a build. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Define the after-build proof that no source was patched (incl. Điều 0-G, v0.1 baseline).

2. Sources / evidence read

Build preflight source snapshot (42); Macro-4 no-production-touch source proof obligations (D47); tool/packet lock. Main process, no reader-agents.

3. Accepted baseline (carried)

No source law/amendment/note/prior report is patched; Điều 0-G not recovered/patched; v0.1-stable not overwritten; v0.2 not promoted.

4. Evidence / analysis — source-unchanged obligation

Source surface	Postflight must be
laws/*, architecture/*, ssot/*	identical to preflight
Điều 0-G birth-registry-law.md + broken anchor	identical (not recovered/patched)
prior macro reports/consolidation	identical
v0.1-stable / FIX7 V3 baseline	identical (not overwritten)

5. Candidate / requirement / gate / result

A build passes PT-2 only if every source surface is byte-identical before/after. No source was patched by this macro (read-only + new KB docs only). The obligation is defined; no comparison run here.

6. Owner-gated future work

Any source change is a separate Owner-gated act; forbidden now.

7. What remains unresolved

Điều 0-G source authority remains No-Go, untouched.

8. Ready for GPT/Codex review

Yes — Codex should confirm the obligation covers source, law, report, and the tool baseline.
