No operational impact is expected. This maintenance includes the following enhancements and improvements:

- Added available alert migration and capability-gated delivery enhancements, including the new client capability flag and migrated available-alert handling across presence and login flows.

- Added inbox expired-entry cleanup sync and zset-size observation/trimming controls, improving inbox consistency across peers and providing better operational visibility for oversized inbox keys.

- Added group session cache support for group publish delivery, reducing repeated session lookups and improving scalability for large group notifications.

- Refactored the WebSocket event-handling architecture, removing the old protocol module, splitting logic into dedicated event-handling components, and introducing non-blocking ACK tracking for better maintainability and delivery reliability.

- Added Push Global Event enhancements, including a dedicated AsyncMQ consume path for global events and connection-side periodic delivery for eligible WebSocket clients.

- Added batch-by-batch UCS lookup support for OID queries, improving stability and performance when handling large UCS group lookups.

- Fixed pub request observability and diagnostics gaps by enhancing access-log output, adding tagged request logging, improving PII-safe logging behavior, and logging requests with missing name or category.

- Fixed RPC behavior in the pub path by enabling keepalive to improve connection reuse and reduce RPC overhead.

- Fixed read-suggestion retrieval logic by introducing a rolling 30-day window so only recent suggestions are considered during fetch.

- Fixed global event delivery behavior by tightening the periodic-push flow, ensuring only eligible authenticated sessions start the background delivery thread, and keeping a single active delivery trigger when periodic push is enabled.

- Fixed WebSocket unregister handling semantics by removing obsolete close-frame unregister logic and clarifying that device cache cleanup is driven by the client unregister flow.

All services are expected to operate normally during the maintenance window.
