0. Status and non-authorization

STATUS: PASS — engineering / decision-prep. Holds B2 to inspect-producer scope; no mega-birth pipeline. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Guarantee the bundling of three lanes does not become a mega-pipeline or mega-registry.

2. Sources / evidence read

Macro-2 no-mega-pipeline invariant check; Owner LEGO invariant. Main process, no reader-agents.

3. Accepted baseline (carried)

B2 must not certify / canonicalize / mint identity / write KG prov / run backlog / flip gates / promote staging→prod / become a mega-birth pipeline.

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

Forbidden over-reach	In this package?
certify (B4)	no
canonical (S4)	no
mint identity (B1/S3)	no
KG provenance (R1)	no
backlog (B5)	no
gate flip (B7)	no
staging→prod promote	no
fused birth-certify pipeline	no

5. Recommendation / matrix / result — drift trigger (→ HOLD)

Any deliverable that makes B2 do more than produce inspect_pen/stamp/gate = B2_OVERREACH / MEGA_BIRTH → HOLD. Status this run: NOT triggered.

6. Owner-gated future work

B2's neighbors (B1/B4/B5/B6/S3/S4) are separate blocks; assembling them is Owner-gated and must preserve the split (Codex caveat).

7. What remains unresolved

B2 boundary holds; neighbors unopened.

8. Ready for GPT/Codex review

Yes — Codex should confirm the three-lane bundle stays three separate surfaces, not one pipeline.
