 ## [Unreleased]
 
+### Fixed
+
+- Shared Team background presence continues after enrollment retries finish.
+  Leaders periodically send a complete authenticated roster, while members
+  retain the leader's roster and announce their own presence. Linux uses the
+  same scheduler as ESP rather than a separate platform implementation.
+- Team member activity and map summaries handle persisted local aliases and
+  mixed uptime/Unix timestamps without showing stale activity as current.
+  Snapshot reload restores its encoded last-update time.
+- A returned local radio identity updates the existing Team "You" entry
+  instead of creating a duplicate member.
+
 ## [1.2.3] - 2026-11-11

+The shared Team background dispatcher sends authenticated status every 30

 The position-ring reader projects the newest timestamp per member. An older

+Team relative-time presentation uses wall-clock seconds when available and
+does not subtract a process uptime from a Unix timestamp. A persisted timestamp
+from a different clock domain is shown as unknown. The local zero-ID alias is
+the running observer, not a stale RF peer; returned local radio identities map
