Fixed Reconnect Race Condition

Output

✅ Fix Applied

Change Made

File: konui/src/console-streaming.ts

- } catch (e) {
-   log('warn', 'stream', ...);
-   if (navigator.onLine) {
-     reconnectWithEventSource(...);
-   }
- }

+ } catch (e) {
+   // Only attempt reconnect if stream didn't complete successfully
+   // This prevents the race condition where stream close triggers error
+   // after normal completion
+   if (streamComplete) {
+     log('debug', 'stream', 'Ignoring error after successful...');
+     return;
+   }
+   log('warn', 'stream', ...);
+   if (navigator.onLine) {
+     reconnectWithEventSource(...);
+   }
+ }

How It Works

The streamComplete flag is set to true when the stream finishes normally (line 279). Now, if the catch block is triggered after a successful completion (due to browser firing an error on stream close), we simply ignore it instead of attempting to reconnect.

✓ Konui Restarted

The fix is now live. The next turn that shows timing data should no longer get stuck in "RECONNECTING..." state.

What's Next?

Test by running a turn that takes long enough to generate timing data, then verify it returns to READY state.
