QA found critical regression: after removing HTTP polling, a WS disconnect left the UI permanently stuck (uxState='running' forever). Fixes: - WS reconnect: up to 3 attempts with 10s backoff on close (non-1000/1005) - App timeout: 600s (10 min) max — transitions to failed if stuck - Stale log message: removed 'falling back to polling' (no longer exists) - Contract header: updated @BRIEF, restored @UX_STATE/@UX_FEEDBACK/@UX_RECOVERY - cleanup(): unified WS close + timer clear (used by stop, timeout, terminal) - onclose handler: triggers reconnect via _handleWsFailure() - onerror handler: defers to onclose (fires after error) - onopen handler: resets _reconnectCount on successful connect - Terminal states: call _cleanup() to stop reconnect timer + timeout Build ✅ 698 tests ✅
