 ## Unreleased
 
+### Synchronisation and storage
+
+#### Fixed
+
+- **Sync on Startup** now runs an immediate Object Storage synchronisation after start-up or resume, including migrated profiles which retain a Continuous setting that Object Storage cannot use.
+- A temporarily unavailable Object Storage synchronisation-parameter read is no longer treated as a missing object and cannot regenerate the shared Security Seed. Flow-specific Security Seed checks also bypass an earlier process-cached result.
+- Local database reset and plug-in unload now retire active replication through its owner before closing the database, without reporting a missing active Replicator or describing unload as a database reset.
+
+### Peer-to-peer synchronisation
+
+#### Fixed
+
+- The P2P Setup connection test no longer interrupts an active P2P room. It observes an active compatible relay binding, blocks a test which would add another relay until P2P is disconnected, and uses a short-lived trial only while P2P is idle.
+- Unattended P2P synchronisation no longer raises Notice-level messages for missing configured targets, authentication rejection, configuration mismatch, or an overlapping transfer. User-initiated operations retain their existing feedback.
