Upcoming:

• Phase 6 Sprint 2: Project Explorer deep-dive, Session Manager enhancements, Volk Status polish

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

• 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

• 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)

Additional fields (from the legacy-format record of this session):

Files Created:

• vizint-ui/gadgets/project-explorer/file-tree.js (231 lines) - Reusable file tree with lazy loading
• vizint-ui/lib/sparkline.js (153 lines) - Canvas sparkline component
• vizint-ui/gadgets/session-manager/deferred-work.js (231 lines) - Deferred work CRUD panel
• vizint-ui/gadgets/session-manager/work-log.js (84 lines) - Work log panel

• vizint-ui/gadgets/audit-trail/gadget.js (734 lines) - Audit trail with CSV/JSON export

Completed:

• All Sprint 2 tasks completed (8/9, 1 skipped)
• 226 frontend unit tests passing (21 files)
• 0 ERRORs in test-review
• Backend: 18093/18094 tests passing

Next Steps:

• Phase 6 Sprint 3: Code Quality & Constitutional Verification
• Task 5.1 deferred to when backend RPC is available

Session Handover:

• Key decisions: FileTree is a standalone component consumed by Project Explorer, Sparkline history tracked in _kgHistory with auto-pruning to 20 points, DeferredWorkPanel and WorkLogPanel mounted in two-column grid below session card, Volk detail panel overlays gadget container (absolute positioning) rather than modal
• Blockers: Task 5.1 (Task Board Detail Panel) skipped — requires backend projects.taskUpdate RPC, Backend: 1 pre-existing test failure (port 8765 conflict in generated gateway test)
• In-progress: Phase 6 Sprint 3: Code Quality & Constitutional Verification
• Important files: vizint-ui/gadgets/project-explorer/file-tree.js, vizint-ui/lib/sparkline.js, vizint-ui/gadgets/session-manager/gadget.js, vizint-ui/gadgets/volk-status/gadget.js
• Commands: cd vizint-ui && npm test, cd vizint-ui && npm run test:review
• Warnings: SessionManager _initPanels requires container to be in DOM — called after _render, Volk Status ResizeObserver needs cleanup on unmount

Note on duplicates: the history file records each of the above sessions twice — once in the summary format shown, and once in a legacy template format ("Focus/Duration/Session Goals/Work Log/Completed/Next Steps"). The legacy records contain the same facts plus unfilled template placeholders; the only substantive extra fields (session 139's Files Created / Completed / Next Steps / Handover) are merged into the corresponding section above.
