- Remove Address field from PartyEndpoint (parties connect to router themselves)
- Update K8s Discovery to only manage PartyID and Role labels
- Add Party registration and SessionEvent protobuf definitions
- Implement PartyRegistry and SessionEventBroadcaster domain logic
- Add RegisterParty and SubscribeSessionEvents gRPC handlers
- Prepare infrastructure for party-driven MPC coordination
This is the first phase of migrating from coordinator-driven to party-driven
architecture following international MPC system design patterns.
- Update account_handler to use real gRPC calls instead of placeholders
- Add sessionCoordinatorClient field to AccountHTTPHandler
- Modify CreateKeygenSession to call session coordinator via gRPC
- Modify CreateSigningSession to call session coordinator via gRPC
- Modify GetSessionStatus to query real session data via gRPC
- Update main.go to initialize and pass sessionCoordinatorClient
- Remove separate mpc_handler.go (consolidated into account_handler)
- Regenerate protobuf files with gRPC service definitions
- Add proper imports for context, time, and grpc adapter
All MPC endpoints now create real sessions with JWT tokens and
can query actual session status from the session coordinator service.
Tested end-to-end: keygen session creation and status query working.
