---

0. Status and non-authorization

STATUS: PASS — engineering / design-only. Holds B2 as the only primary block, inspect producer only. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Keep the macro's primary scope to B2's inspect-producer role and nothing more.

2. Sources / evidence read

Macro-4 no-mega-birth-pipeline lock (D70); B2 production-firewall (D35); inspect-producer baseline. Main process, no reader-agents.

3. Accepted baseline (carried)

B2 = inspect producer only; must not certify, canonicalize, mint identity, write KG, run backlog, flip gates, or promote.

4. Evidence / analysis — B2 boundary check (CLEAN)

Forbidden over-reach	In Macro-5?
certify (B4)	no
canonical (S4/B6)	no
mint identity (B1/S3)	no
KG provenance (R1)	no
backlog (B5)	no
gate flip (B7)	no
staging→prod promote	no

5. Candidate / requirement / gate / result

Macro-5 deepens B2 only (staging authorization + candidate contracts); any deliverable making B2 do more = B2_OVERREACH → HOLD. Status this run: NOT triggered.

6. Owner-gated future work

B2's neighbors (B1/B4/B6/K-lane) are separate Owner-gated blocks; not opened here.

7. What remains unresolved

B2 remains the only primary block.

8. Ready for GPT/Codex review

Yes — Codex should confirm only B2 is deepened.
