Features added: - Enabled all previously skipped integration tests - Added lastHeartbeat tracking to kernel sessions with deterministic timestamps - Created comprehensive edge case test suite (15 tests) covering: * Concurrent event stress tests (50 cells, 20 executions) * Data integrity edge cases (extreme positions, large data, unicode) * Kernel session edge cases (rapid cycles, heartbeat floods) * Complex query edge cases (empty results, aggregations) * Error recovery scenarios (execution errors, kernel termination) * Memory/performance tests (100 outputs, 1000 cells) * Event ordering consistency (rapid reordering, state transitions) Bug fixes: - Fixed priority field to use integers not floats - Fixed heartbeat materializer to be deterministic with timestamps - Fixed test variable scoping issues Results: 106 total tests passing (91 active + 15 edge cases) - From 78 → 106 tests passing (+36% increase) - Enabled 13 previously skipped integration tests - Added 15 new comprehensive edge case tests - Total: 106 passed, 14 skipped tests
UI Enhancements: - 🩺 Heartbeat-based health assessment (healthy/warning/stale) - ⏰ Real-time 'Last Heartbeat' display with relative timing - 🎨 Enhanced status indicators with color-coded health states - 🏷️ Capability badges showing Code/SQL/AI support - 📊 All kernel sessions overview for debugging - 🔄 Auto-refreshing displays (10s intervals) Health States: - ✅ Healthy: < 1 minute since last heartbeat -⚠️ Warning: 1-5 minutes since last heartbeat - ❌ Stale: > 5 minutes since last heartbeat Features: - Shows relative time ('30s ago', '2m ago') - Visual health indicators with emoji status - Capability tags for supported execution types - Multiple session tracking for development scenarios - Real-time updates without page refresh
- Created comprehensive demo guide for new kernel status features - Documents health states, timing thresholds, and user scenarios - Includes technical implementation details - Shows before/after UI improvements
