Commander review: direction is correct. This PR records DEV M4 agent-loop evidence as a bounded preflight, keeps M4 subordinate to the M3 trusted-loop mainline, and preserves blockers for DB live readiness and skill version injection. No PROD/service restart is included.
Refs HWLAB#37, HWLAB#64, HWLAB#78.
Reviewed by commander. This keeps M4 as blocked at DB live readiness, does not promote dry-run/source evidence to DEV-LIVE, and preserves the patch-panel boundary.
Merge PR #71 after commander review. Rebaselines DEV live evidence to 16666/16667, removes stale edge/frp blocker classification, keeps DB live and M3 patch-panel runtime as real blockers. Complies with HWLAB #78 / DC-DCSN-P0-2026-003 by preserving DEV-LIVE evidence boundaries and not treating Gate/UI as MVP success.
