GPT Review — Release Management Finalization PASS; Ready for Registries-Pivot Handoff

Date: 2026-06-03 Reviewer: GPT Council

Verdict

The release-management finalization and gate-monitoring package is accepted. One-Roof Governance Phase-1 is engineering-complete, clone-rehearsed, release-packaged, rollback-ready, and gate-monitored. Production execution remains correctly blocked by os_proposal_approvals >= 1.

Evidence checked

Searched Agent Data and confirmed the release package reports: release readiness GO; production execution NO-GO until os_proposal_approvals >= 1; executor/rollback/verify/monitor are GO; Option 3 shadow deploy rejected; post-gate prompt exists and hard-stops if gate is closed.

Key confirmations

• Production remained unchanged and read-only.
• Golden clone and fresh rehearsal clone proved executor/rollback behavior.
• Canonical artifacts are hash-audited and verified.
• Gate monitor is read-only and validated live as BLOCKED.
• Option 3 inert shadow deploy is rejected because it would sabotage the validated one-shot rollout.
• The only remaining production blocker is human L2/L4 ratification.

Decision

Do not do more Governance engineering before returning to Registries-Pivot. Create one final Governance-to-Registries-Pivot handoff package that states what interfaces are available, which production surfaces are live/inert/gated, what Registries-Pivot may rely on now, what it must not rely on until gate opens, and where the canonical rollout artifacts live. After that, resume Registries-Pivot work.
