====== v6.7.21: Internal maintenance bridge ======

**Internal compatible worker bridge**, not another player feature redesign. Includes [[updates:v6_7_20|v6.7.20's Jump changes]] and earlier cumulative features.

===== Purpose =====
Prepares the existing shared supervisor for the owner-approved [[updates:v6_7_22|v6.7.22 coordinated maintenance window]] without forcing occupied rooms to close.

The operator-only gate can temporarily make a confirmed empty, idle room private. A late join cancels the attempt and restores public access. Expired or removed requests release confirmed gates. Unknown lock/unlock outcomes require reconciliation instead of guessing that a network operation failed. The gate never kicks players or closes rooms itself.

This bridge keeps the existing shared-service fingerprints and installs through ordinary empty-safe per-room updates. It does **not** make the supervisor's five-second wait live.

===== Dated rollout =====
October 5, 2026, 15:11 PDT: Rooms 2–4 ran v6.7.21; Room 1 ran v6.7.20 and waited for v6.7.21 while occupied. The shared supervisor remained v6.7.2, with its 30-second update wait. All room errors were null. Check [[status:start|Live lobbies]] for later availability.
