10-17: LGTM!The changelog entry accurately documents the Error Boundary feature, including technical details about the hybrid Class+Functional approach and the dual-theme support.
.Jules/knowledge.md (2)
90-116: LGTM!The Error Boundary pattern documentation is well-structured, clearly explaining the class/functional split pattern for using hooks in error fallback UIs. The testing tip about render vs event handler errors is an important detail.
489-511: LGTM!The implementation review captures key learnings effectively, particularly the note about Error Boundaries only catching render/lifecycle errors and the need to wrap Router for navigation hooks.
web/components/ErrorBoundary.tsx (3)
1-16: LGTM!Imports and type definitions are well-organized. The Props and State interfaces are properly typed for the error boundary pattern.
18-59: LGTM!The ErrorFallback component correctly leverages hooks within a functional component while delegating error catching to the class boundary. Good accessibility practices:
aria-hidden="true"on the decorative iconrole="alert"on the error heading- Buttons have visible text labels
The
handleHomefunction properly resets the error state before navigation, preventing stale error state issues.
61-86: LGTM!The ErrorBoundary class follows React's recommended pattern:
getDerivedStateFromErrorcaptures errors synchronously for rendercomponentDidCatchlogs errors (consider adding external error reporting in the future)resetErrorBoundaryis defined as an arrow function for stable reference when passed to the fallbackweb/App.tsx (2)
9-9: LGTM!Import is correctly placed alongside other component imports.
55-57: LGTM!The ErrorBoundary is correctly positioned:
- Inside
HashRouter— enablesuseNavigatein the fallback UI- Inside
ThemeProvider— enablesuseThemein the fallback UI- Wrapping
AppRoutes— catches render errors from all route componentsThis placement ensures the fallback UI has access to all required contexts while protecting the main application routes.

Stale placeholder text remains after completed tasks.
Line 162 states "No tasks completed yet. Move tasks here after completion." but there are already four completed tasks listed above it. This placeholder should be removed.
