Purpose
VizInt Phase 6 Sprint 1: Resilience Foundation
Objectives
- Implement ErrorBoundary with retry logic and metrics integration
- Add auto-re-subscription tracking to WebSocketBridge
- Build MetricsCollector core with FPS/memory/RPC tracking
- Create DebugPanel gadget for dev diagnostics
- Implement PerformanceOverlay floating HUD
- Add read-only mode when disconnected
- Handle localStorage quota exceeded gracefully
- Write unit tests for ErrorBoundary, MetricsCollector, WebSocketBridge
Work log
- ErrorBoundary implementation at 2026-05-26 18:46
Details:
- Created lib/error-boundary.js with wrapMount(), retry(), reset()
- Emits vizint:error CustomEvent
- Integrates with MetricsCollector for error tracking
- CSS error overlay with retry button
- 7 unit tests passing
- WebSocketBridge resilience at 2026-05-26 18:46
Details:
- Added _subSpecs Map for subscription topic/filters tracking
- _resubscribeAll() called on reconnect
- RPC latency tracked via performance.now()
- Queue tests: 101 calls discards oldest, reconnect flushes queue
- Re-subscription test verifies push delivery after reconnect
- MetricsCollector core at 2026-05-26 18:46
Details:
- lib/metrics.js with render/RPC/event/memory/FPS/error tracking
- getSnapshot() returns structuredClone of data
- getReport() returns formatted string
- FPS loop via requestAnimationFrame, memory via performance.memory
- 7 unit tests passing
- DebugPanel gadget at 2026-05-26 18:46
Details:
- gadgets/debug-panel/gadget.js consumes window.__vizintMetricsCollector
- Shows connection state, FPS, memory, error log
- Copy Report and Clear Errors actions
- Auto-refreshes every 2s
- PerformanceOverlay at 2026-05-26 18:46
Details:
- lib/performance-overlay.js floating HUD
- FPS + memory display, bottom-right fixed position
- Toggleable via stateSync perfOverlay key
- Read-only mode at 2026-05-26 18:46
Details:
- data-readonly attribute toggled on #app root in _updateConnectionStatus()
- CSS dims grid (opacity 0.75) and disables inputs when offline
- No manual class management on individual gadgets
- localStorage quota handling at 2026-05-26 18:46
Details:
- StateSync._evictOldest() removes oldest commandcenter.state.* entry
- Called on QuotaExceededError in set() and pullRemote()
- Graceful fallback without crashing
- Frontend test suite at 2026-05-26 18:46
Details:
- 226 tests passing across 21 test files
- 0 ERRORs in test-review script
- New tests: error-boundary (7), metrics (7), websocket-bridge (3 new)
Artifacts
- vizint-ui/lib/error-boundary.js (129 lines) - Gadget error boundary with retry and metrics integration- vizint-ui/lib/metrics.js (158 lines) - Performance telemetry collector- vizint-ui/lib/performance-overlay.js (73 lines) - Floating FPS/memory HUD- vizint-ui/gadgets/debug-panel/gadget.js (174 lines) - Dev diagnostics gadget- vizint-ui/bridge/websocket-bridge.js (239 lines) - Enhanced with auto-re-subscription and RPC latency tracking- vizint-ui/bridge/state-sync.js (184 lines) - Quota exceeded handling with eviction- vizint-ui/tests/unit/error-boundary.test.js (80 lines) - ErrorBoundary unit tests- vizint-ui/tests/unit/metrics.test.js (66 lines) - MetricsCollector unit tests
Achievements
- All 9 Sprint 1 tasks completed
- 226 frontend unit tests passing (21 files)
- 0 ERRORs in test-review
- Backend: 18093/18094 tests passing (1 pre-existing failure)
Upcoming
- Phase 6 Sprint 2: Project Explorer deep-dive, Session Manager enhancements, Volk Status polish
Handoff
Decisions: ErrorBoundary dispatches vizint:error CustomEvent for global handling, MetricsCollector attached to window.__vizintMetricsCollector for cross-module access, DebugPanel is a regular gadget (not overlay) to avoid z-index complexity, Read-only mode uses data-readonly attribute on app root instead of per-gadget classes Blockers: Backend: 1 pre-existing test failure (port 8765 conflict in generated gateway test), E2E tests not re-run after Sprint 1 changes (Playwright suite) Active Work: Phase 6 Sprint 2: Project Explorer deep-dive + Session Manager enhancements Key Files: vizint-ui/app.js, vizint-ui/lib/error-boundary.js, vizint-ui/bridge/websocket-bridge.js, vizint-ui/lib/metrics.js Commands: cd vizint-ui && npm test, cd vizint-ui && npm run test:review Alerts: MetricsCollector.start() must be stopped on app.destroy() to prevent RAF leaks, WebSocketBridge _resubscribeAll() sends subscribe RPCs but does not re-register client-side handlers (they persist in _subs Map)
