v0.6.2

What changed

Cross-Platform Device Sync 0.6.2 adds guarded Matterbridge runtime recovery for enabled background synchronization.

This integration synchronizes Home Assistant-side entity exposure lists. It is not a Home Assistant backup, failover, clustering, migration, or instance-to-instance replication tool, and it does not copy automations, history, settings, or entity states.

• Waits for a verified Matterbridge backup archive before recovery.
• Restarts matterbridge-hass first.
• Uses at most one full Matterbridge process restart when exact runtime readback still does not converge.
• Shares a five-minute recovery cooldown across Config Entry reloads.
• Retries persistent failures after 15, 30, 60, 120, then 300 seconds.
• Validates Matterbridge runtime and loaded devices when Matterbridge is used as either a source or target.
• Keeps unsafe or ambiguous conditions fail closed.

The integration manages Home Assistant-side exposure configuration only. It never turns devices on or off and never controls entity state.

Before updating

1. Create a full Home Assistant backup.
2. Confirm Matterbridge and matterbridge-hass are already connected if you use Matterbridge.
3. After updating, restart Home Assistant.
4. Run platform_sync.preview and review additions and removals before a major synchronization.
