Problem:
- Android initiator/joiner could miss session_started events due to race condition
- Events arriving between joinSession() and _currentSession.value assignment were ignored
- This caused keygen timeout because parties never started the TSS protocol
Solution:
- Add pendingSessionId field set BEFORE joinSession() call
- Modify startSessionEventSubscription() to match events against both activeSession and pendingSessionId
- Clear pendingSessionId on session completion, failure, or cancellation
This ensures session_started events are correctly processed even if they arrive
before _currentSession is fully initialized.

Changed from single 2-second delay to 5 attempts at 500ms intervals.
This provides faster detection while covering a longer window (2.5 seconds total).
The polling loop:
- Checks every 500ms for up to 5 times
- Stops immediately if keygen is already triggered
- Stops if session context changes (user cancelled/navigated away)
This handles the case where the last joiner triggers session_started
but cannot receive the event themselves.

When multiple Android devices join a keygen session nearly simultaneously,
the last joiner may miss the session_started gRPC event because it's sent
before the device has fully set up its event subscription.
This fix adds a 2-second delayed polling check after join to detect if
the session has already started. If the session is in_progress and we
haven't started keygen yet, trigger it via polling instead of relying
solely on the session_started event.

When signing with fewer parties than keygen (e.g., 2-of-3 signing with only 2 parties),
the TSS-lib requires filtered save data containing only the participating parties.
Without this fix, signing fails with "U doesn't equal T" error because:
- Keygen creates save data for all N parties (e.g., 3 parties with indices 0, 1, 2)
- Sign uses only T parties (e.g., 2 parties with indices 1, 2)

When switching message/event streams, the old stream's 'end' or 'error'
events could fire after the new stream was created. Since activeMessageSubscription
was already updated to the new session, the old stream's events would
incorrectly trigger reconnection, causing TSS message routing to fail.

- Remove event listeners from old stream before canceling
- Use closure to capture current stream reference
- Check if event is from current active stream before triggering reconnect
This fixes the "Not connected" error during co-sign TSS message routing.

- This fixes TSS signing failure "U doesn't equal T" caused by mismatched n values

Problem: Participants joining early only got incomplete participant list
from other_parties (only those who had joined), causing partyIndex mismatch.
Solution:
- Add parties field to SessionInfo (from validateInviteCode response)
- Pass parties to joinSession call from frontend
- Backend joinSession uses params.parties (complete list) instead of
result.other_parties (incomplete list)
- Add debug logging to track participant list state
Now all participants have the complete parties list with correct partyIndex.

Add console.log statements to trace the auto-join logic:
- Log loaded shares with sessionId
- Log auto-select share matching check
- Log auto-join conditions and share match status
- Log validateInviteCode results including joinToken
- Log handleJoinSession parameters

When multiple sign sessions share the same invite code (due to retries),
the query now:
1. Excludes failed sessions (status != 'failed')
2. Orders by created_at DESC to get the most recent session
3. Limits to 1 result
This prevents participants from seeing an old failed session's status
when they look up the invite code.

The validateSigningSession handler was using parties.length for threshold.n
which returned 0 when parties array was empty. Now correctly uses the
threshold_n value returned from the backend API.

Add complete co-sign functionality for multi-party transaction signing:
Frontend (React):
- CoSignCreate.tsx: Create signing session with share selection
- CoSignJoin.tsx: Join signing session via invite code
- CoSignSession.tsx: Monitor signing progress and results
- Add routes in App.tsx for new pages
Backend (Electron):
- main.ts: Add IPC handlers for co-sign operations
- tss-handler.ts: Add participateSign() for TSS signing
- preload.ts: Expose cosign API to renderer
- account-client.ts: Add sign session API types
TSS Party (Go):
- main.go: Implement 'sign' command for GG20 signing protocol
- integration_test.go: Add comprehensive tests for signing flow
Infrastructure:
- docker-compose.windows.yml: Expose gRPC port 50051
This is a pure additive change that does not affect existing
persistent role keygen/sign functionality.

Add new ExecuteWithSessionInfo method to ParticipateKeygenUseCase
for server-party-co-managed to skip duplicate JoinSession call.
- server-party-co-managed already calls JoinSession in session_created phase
- ExecuteWithSessionInfo accepts pre-obtained SessionInfo and skips internal JoinSession
- Refactor common execution logic to private executeWithSessionInfo method
- Update server-party-co-managed to use ExecuteWithSessionInfo on session_started

- Create new server-party-co-managed service with two-phase event handling
- Phase 1 (session_created): Store join token and wait
- Phase 2 (session_started): Execute TSS protocol (same timing as service-party-app)
- Add PartyRoleCoManagedPersistent role to isolate from normal keygen/sign
- Update docker-compose.yml with 3 co-managed party instances
- Update deploy.sh service lists
- Modify selectPartiesByCompositionForCoManaged to use new role
This ensures co_managed_keygen sessions use dedicated parties that behave
100% compatible with service-party-app, without affecting existing keygen/sign flows.

Problem:
- co_managed_keygen server-party waits for external party after joining
- No heartbeat sent during wait period (up to 5 minutes)
- session-coordinator has 120 second inactivity timeout
- Server-party marked as timed_out/failed while waiting
Fix:
- Send heartbeat in waitForAllParticipants polling loop
- Add Heartbeat method to MessageRouterClient interface
- Heartbeat every 2 seconds with poll interval
- Heartbeat failure only logs warning, does not block
