fix: allow phone registration reassignment - #7
Conversation
📝 WalkthroughWalkthroughPhone registration now transfers to the latest participant. Conflicting registrations are removed, existing registrations are reassigned, and timestamps are refreshed. Tests verify that only the latest device can initiate an outgoing call. ChangesPhone registration reassignment
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to Phone reassignment can fail for concurrent registration requests because competing updates may trigger an unhandled database conflict, causing users to receive errors instead of a successful transfer. Merge should wait for serialization or conflict retry, or receive explicit owner acceptance of this risk. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

Serialize concurrent registration transfers.
CallService.registerPhone reads PhoneRegistration without a lock. Concurrent requests for the same participantKey can both find no capability row and create registrations with the same unique capabilityHash. One transaction can then fail with DataIntegrityViolationException, which this method does not catch or retry. Serialize registration by a stable participant key, or retry the conflict before returning success. Add a bounded concurrent registration test.
