A 502 Bad Gateway is a server/gateway error, not a network error.
Logging it as a 'Session validation network error' is noisy and
misleading during startup when nginx is temporarily unreachable.
Silently skip the console.warn for 5xx errors in handleValidationError
while keeping the warning for actual network errors.
Allow useNavigationAbortSignal to opt out of navigation-based abort
for long-lived background tasks like polling. Set ignoreCancellation: true
to keep requests alive across route changes.

- client.ts: store correlation ID in sessionStorage so HMR (module re-eval)
does not generate a new ID mid-session; add clearSessionCorrelationId()
- endpoints.ts: fix 3 template literal trailing-quote bugs (missing ')' chars);
replace template literals with string concat for encodeURIComponent calls
- AuthProvider.tsx: call clearSessionCorrelationId() on logout
- App.tsx: reorder ThemeProvider import before AuthProvider per PROVIDER_ORDER.md;
indent Routes inside AuthProvider to match expected tree structure
- Tasks.md: update task status
- providerTreeOrder.test.tsx: add integration tests for provider nesting order

Previously the AbortController was created inside useEffect, which runs
after render. This meant requests initiated during render received
the previous cycle's (possibly aborted) signal and were cancelled
immediately instead of completing.
Now the controller is created synchronously when pathname changes, before
any request can be initiated on the new route. The old controller is
aborted in the same conditional block, before the new one is created.
Side effect: removed resolved Issue #49 from Tasks.md.

- LoginPage now shows a loading spinner while validating the session
- Redirect to dashboard automatically once validation completes and session is valid
- Expose isValidating state through AuthProvider for components to track validation status
- Update useAuth hook to return isValidating along with isAuthenticated

- Add BroadcastChannel API for real-time logout synchronization across tabs
- Implement storage event listener as fallback for older browsers
- When a user logs out in one tab, all other tabs immediately reflect the logout state
- Update tests to verify storage event and BroadcastChannel behavior
- Update Architecture.md to document cross-tab synchronization
- Update Web-Development.md with authentication state management notes
The provider now broadcasts logout messages to other tabs so they immediately
reflect the logout state without requiring a page refresh or additional API calls.
The implementation uses BroadcastChannel as the primary sync mechanism with
storage events as a fallback for older browsers.

Adds a navigation-aware request cancellation mechanism that automatically
aborts all route-specific API requests when the user navigates to a
different route. This prevents silent state-update errors from responses
arriving after component unmount and conserves bandwidth by cancelling
now-irrelevant requests.
Key additions:
- NavigationCancellationContext: Context for managing route-specific signals
- NavigationCancellationProvider: Provider that detects route changes and
aborts all signals from the previous route
- useNavigationAbortSignal hook: Allows components to subscribe to
navigation-aware cancellation signals
- Comprehensive tests for the cancellation lifecycle
- Documentation in Web-Development.md for request lifecycle policy
The provider is placed in the app hierarchy between BrowserRouter and
AuthProvider, ensuring consistent cancellation behavior across all routes.
Long-lived background tasks (polling, session validation) can opt-out by
managing their own AbortController lifecycle.
Closes#23 from Tasks.md: No global cancellation policy on route transitions

- Move magic strings from AuthProvider, MainLayout, and ThemeProvider to
frontend/src/utils/constants.ts
- Add STORAGE_KEY_AUTHENTICATED, STORAGE_KEY_SIDEBAR_COLLAPSED, and
STORAGE_KEY_THEME constants with JSDoc descriptions
- Update all three files to import and use centralized keys
- Prevents key drift and typo regressions across the frontend

- Add setAuthErrorHandler() registration mechanism to utils/fetchError.ts
- Implement fallback logging when auth errors (401/403) occur without registered handler
- Update AuthProvider to register both API client and fetch error handlers
- Ensure auth errors are handled deterministically at multiple layers
- Add comprehensive tests for auth error handler registration and fallback logging
- Update Web-Development.md documentation with auth error handling contract
Fixes issue #21: Silent auth errors are now caught and logged if the handler is not
registered, preventing actionable errors from being silently swallowed.

This addresses issue #19 by making the implicit provider dependency order
explicit and order-sensitive.
Changes:
1. Created PROVIDER_ORDER.md - comprehensive documentation explaining:
- The provider hierarchy from outermost to innermost
- Why each provider must be at its position
- Order-sensitive pitfalls and what would break
- Guidelines for adding new providers in the future
2. Added provider composition tests (providerComposition.test.tsx):
- 13 comprehensive tests validating provider order and dependencies
- Tests verify all providers mount correctly
- Tests check that hooks only work inside correct providers
- Tests validate async initialization (AuthProvider, TimezoneProvider)
- Tests verify theme persistence and notification propagation
3. Updated App.tsx with inline documentation:
- Added detailed provider order contract in JSDoc header
- Inline comments explaining each provider's position
- Reference to PROVIDER_ORDER.md for detailed rationale
4. Updated Web-Development.md:
- Added new section 5.5 'Provider Order Contract'
- Documents provider hierarchy and rationale
- Links to comprehensive provider documentation
- References regression test suite
All tests pass. TypeScript compilation succeeds. Build succeeds.
The provider order is now explicit and future refactors can validate
compliance through the regression test suite.

Validates session on app mount by calling GET /api/auth/session instead of relying
solely on cached sessionStorage. This ensures the UI state always reflects server
reality — expired or revoked sessions are detected immediately.
Changes:
- Backend: Add GET /api/auth/session endpoint (requires valid session, returns 200/401)
- Frontend: Add useSessionValidation hook for mount-time validation
- Frontend: Add SessionValidationLoading component for validation spinner
- Frontend: Update AuthProvider to call validation on mount with loading state
- Frontend: Add validateSession API function
- Docs: Update Features.md with session validation behavior
- Docs: Update Web-Development.md with session validation pattern
Handles three outcomes:
1. Valid session (200): Proceed with cached state
2. Invalid session (401): Clear sessionStorage and redirect to login
3. Network error: Don't logout (backend may be temporarily unreachable)

- Update AuthProvider with improved error handling and token management
- Enhance API client with better request/response handling
- Add comprehensive test coverage for auth flows
- Update documentation with current tasks

- Remove JWT token and expires_at from sessionStorage
- Simplify AuthProvider to use boolean isAuthenticated flag
- Persist only isAuthenticated boolean for page-reload continuity
- Update AuthProvider test to verify new auth model
- Add comprehensive auth documentation to Web-Development.md explaining:
- Cookie-based authentication model
- How frontend auth state persists
- Why tokens are no longer stored
- Error handling flow for 401/403 responses
The authentication model is cookie-based: the backend sets bangui_session
cookie on login, frontend automatically includes it via credentials:
'include', and the backend is the sole authority on session validity.
Previously stored tokens were never actually used and made the auth model
misleading during development.
Fixes TASK-STATE-04.

- DashboardFilterBar now requires all filter props (timeRange, onTimeRangeChange, originFilter, onOriginFilterChange) instead of falling back to context
- Removed useDashboardFilters() hook dependency from DashboardFilterBar, BanTrendChart, and JailDistributionChart
- Updated DashboardPage to explicitly pass all filter values and callbacks from context to components
- Made props required on BanTrendChart and JailDistributionChart
- Updated all tests to reflect new prop requirements
- This eliminates the silent dual-source behavior that could lead to subtle bugs when components are used with different data sources
