Status Update - Waker Registration Issue Fixed ✅

Progress

The waker registration issue (#1944) that was blocking ubertest has been fixed and merged to main. The fix involved refactoring the priority_select combinator to properly maintain future state across polls.

Current Test Status

Running test_basic_room_creation now shows:

✅ Gateway and peer successfully connect - handshake working correctly
✅ Keep-alive packets being exchanged - connection is stable
❌ PUT operation times out - riverctl receives "Timeout waiting for PUT response after 10 seconds"

Root Cause Analysis

The test output shows:

Nodes start and bootstrap successfully
Gateway ← → Peer connection establishes properly
Keep-alive packets flow bidirectionally
riverctl sends room creation request (PUT operation)
PUT times out after 10 seconds without response
WebSocket connection closes: "Connection reset without closing handshake"

Likely Issues

The PUT timeout suggests one of:

Operation state machine not processing PUT correctly
Response routing not delivering result back to client
Contract execution failing silently
Message handling in event loop not waking on PUT completion

Next Steps

Add detailed logging for PUT operation path
Trace where the PUT request gets stuck
Verify notify_op_change() is being called when PUT completes
Check if result is being routed back to riverctl client correctly

Branch

Working in fix/uber-test-debug-1932 which now includes the priority_select fix from main.
