Why: The approved U6 plan requires a reviewable account of three real serial deliveries, CI costs, recovery paths, and manual adoption limits.
Evidence: Dev #489/#488/#486 fixed-head Actions runs 3038/3050/3067 and main runs 3040/3053/3068; component PRs and Issue #518 preserve raw SELF and independent REPLAY.
Impact: Document observed behavior and untested automatic coordination boundaries without changing product code or declaring rollout authority.
