- Add PartyIndex field to protobuf ParticipantInfo message
- Pass original PartyIndex from account shares to session coordinator
- Use original PartyIndex instead of loop variable when creating participants
- This fixes TSS signing failures when non-consecutive parties are selected
Add logging at key points to trace keygen_session_id flow:
- Account Handler: log keygen_session_id when creating signing session
- Session Coordinator: log keygen_session_id in CreateSession and JoinSession
- Message Router: log keygen_session_id when proxying JoinSession
- Server Party: log keygen_session_id when joining session

- Add keygen_session_id field to CreateSessionRequest and SessionInfo protobuf
- Modify CreateSigningSessionAuto to accept and pass keygenSessionID
- Update Account Handler to pass account's keygen_session_id when creating signing session
- This enables parties to load the correct keyshare by session ID
TSS threshold semantics: for threshold parameter t, the required number of signers is t+1.
For 2-of-3 with t=2, we need 2+1=3 signers (all parties must participate).
Previous error: 't+1=3 is not satisfied by the key count of 2'
Fix: Changed from selecting t parties to selecting t+1 parties.

For 2-of-3 threshold signing, only 2 parties should participate in signing, not all 3. This fixes the 'failed to calculate Bob_mid' error that occurred when all parties tried to sign.
Changes:
- Modified CreateSigningSession to select exactly threshold_t parties when no signing config exists
- For 2-of-3: now selects 2 parties instead of all 3
- Added logging to show party selection details

- Add SessionEventRepository interface for append-only event storage
- Implement PostgreSQL session_event_repo with immutable event log
- Add database migration for session_events table with indexes
- Record events for keygen and sign session creation
- Record events for signing-config APIs (set, update, clear)

- Add signing-config API endpoints (POST/PUT/DELETE/GET) for configuring
which parties should participate in signing operations
- Add SigningParties field to Account entity with database migration
- Modify CreateSigningSession to use configured parties if set,
otherwise use all active parties (backward compatible)
- Add delegate party signing support: user provides encrypted share
at sign time for delegate party to use
- Update protobuf definitions for DelegateUserShare in session events
- Add ShareTypeDelegate to support hybrid custody model
API endpoints:
- POST /accounts/:id/signing-config - Set signing parties (first time)
- PUT /accounts/:id/signing-config - Update signing parties
- DELETE /accounts/:id/signing-config - Clear config (use all parties)
- GET /accounts/:id/signing-config - Get current configuration

- 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.
Changes:
- Modified CreateAccountRequest to make email optional (omitempty)
- Changed Account.Email from string to *string pointer type
- Updated PostgreSQL repository to handle nullable email with sql.NullString
- Username remains required and auto-generated by identity-service
This supports anonymous account creation without requiring email registration.

Added debug logging to track participant details including party_index in:
- account service MPC keygen handler
- session coordinator gRPC client
- session coordinator gRPC handler
This helps debug the party index assignment issue where all parties
were receiving index 0 instead of unique indices (0, 1, 2).

- 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.
- Add SessionCoordinatorClient gRPC adapter with connection retry logic
- Implement MPCHandler with real gRPC calls to session-coordinator
- Replace placeholder implementation with actual session creation
- Add keygen and signing session endpoints with proper validation
- Include comprehensive implementation summary documentation
This enables account-service to create real MPC sessions via gRPC
instead of returning mock data. Requires main.go integration to activate.
- Created .env.example files with comprehensive security warnings
- Removed hardcoded IP addresses and credentials from docker-compose files
- Made database passwords mandatory (fail-fast on missing config)
- Removed Chinese mirror sources from all Dockerfiles
- Enhanced deploy.sh scripts with .env validation and auto-creation
- Added comprehensive README.md deployment guides
- Changed ALLOWED_IPS default to enable cross-server deployment
- Updated all docker-compose files to use environment variables

Major changes:
- Add TSS core library (pkg/tss) with keygen and signing protocols
- Implement gRPC clients for Server Party service
- Add MPC session endpoints to Account service
- Deploy 3 Server Party instances in docker-compose
- Add MarkPartyReady and StartSession to proto definitions
- Complete integration tests for 2-of-3, 3-of-5, 4-of-7 thresholds
- Add comprehensive documentation (architecture, API, testing, deployment)
Test results:
- 2-of-3: PASSED (keygen 93s, signing 80s)
- 3-of-5: PASSED (keygen 198s, signing 120s)
- 4-of-7: PASSED (keygen 221s, signing 150s)

- Add encoding/hex import to account handler
- Encode challenge as hex string in GenerateChallenge handler
- Decode hex-encoded challenge and signature in Login handler
- Decode hex-encoded public key in CompleteRecovery handler
This fixes compatibility between the test client (which uses hex encoding)
and the server handlers.
