---

0. Status and non-authorization

STATUS: PASS — engineering / design-only. Holds B5 (backlog) and B7 (gate/GUC policy) as dependency-only, not opened. Engineering PASS ≠ authority PASS. Default: HOLD.

1. Purpose

Guarantee Macro-4 does not open B5 or B7 as active workstreams.

2. Sources / evidence read

Macro-3 B5/B7 scope lock; inspect-producer §11 (manual one-shot = B5)/§5 (B7 separate); FRESH dot_config switches. Main process, no reader-agents.

3. Accepted baseline (carried)

B2 = inspect producer only. B5 = backlog pass (the 2026-03-21 one-shot belongs here, not B2). B7 = gate/GUC policy. Both are dependencies, referenced not redesigned.

4. Evidence / analysis

Macro-4 references B5 only to say "manual one-shot = B5 not B2" (channel/firewall) and B7 only to say the gate policy stays as-is (FRESH: app.birth_gate_mode warn-mode inherited; process/queue switches OFF; no warn→block flip). Neither is designed, opened, or modified. The 1.21M backlog is evidence/urgency, not a B5 work item opened here.

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

Any active design/implementation of B5 backlog draining or B7 gate-mode change = B5_B7_SCOPE_CREEP → HOLD. Status this run: NOT triggered.

6. Owner-gated future work

Opening B5 or B7 is a separate Owner-gated package; forbidden now.

7. What remains unresolved

B5/B7 remain unopened dependencies.

8. Ready for GPT/Codex review

Yes — Codex should scan for any B5/B7 active-workstream leakage.
