---

0. Status and non-authorization

STATUS: PASS — engineering / decision-prep. The locks Macro-4 must carry forward. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Pre-commit the safety constraints for the next macro so they cannot be quietly dropped.

2. Sources / evidence read

Macro-2 macro3-preconditions+safety-locks; this package's locks (D14/D21/D30/D33/D41/D42/D43). Main process, no reader-agents.

3. Accepted baseline (carried)

Each macro inherits all prior locks and adds none that weaken them.

4. Evidence / analysis — Macro-4 locks

#	Lock
M4-L1	B2 remains the only primary block (inspect producer only)
M4-L2	B5/B7 dependency-only; R1/KG cross-check-only
M4-L3	Design-only until a separate write-authorization; no implementation
M4-L4	Staging-first + promotion firewall; no prod touch
M4-L5	Channel stays internal/replaceable; no channel-as-authority
M4-L6	Owner gates non-waivable (GATE-4 channel, GATE-5 owner)
M4-L7	v0.1/FIX7 V3 not overwritten; v0.2 not authority
M4-L8	Engineering PASS ≠ authority PASS; default HOLD

5. Recommendation / matrix / result

Macro-4 must open with M4-L1…L8 restated and a self-check that none is weakened.

6. Owner-gated future work

Macro-4 launch is Owner-gated; forbidden now.

7. What remains unresolved

Macro-4 not launched.

8. Ready for GPT/Codex review

Yes — Codex should confirm these locks are at least as strong as Macro-3's.
