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.

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.

- Add optional requestKey parameter to UseFetchDataOptions
- Implement module-level cache (inFlightRequests) to track in-flight requests
- When requestKey is provided, multiple hook instances with same key share in-flight requests
- Prevents duplicate API calls when multiple components fetch same data or rapid refresh calls
- Cache entries are automatically cleared when response arrives (success or error)
- Maintains backward compatibility: without requestKey, behaves as before
- Adds comprehensive tests for deduplication scenarios
This reduces bandwidth waste and prevents race conditions caused by concurrent requests for identical data.

Add AbortController refs and abort signal checks to prevent race conditions
and memory leaks when components unmount or new requests are initiated.
Components fixed:
- JailsTab.tsx: validation handler with AbortController pattern
- JailInfoSection.tsx: handle function with useCallback wrapper
- RawConfigSection.tsx: fetch handler with abort checks
- ConfFilesTab.tsx: file fetch handler with abort signal verification
- IgnoreListSection.tsx: three handlers (add, remove, toggle) with callbacks
All handlers now:
1. Abort previous requests before initiating new ones
2. Create and store new AbortController instances
3. Check abort status before state updates in .then()/.catch()
4. Include cleanup effects that abort on unmount

Add automated type synchronization from backend OpenAPI schema to frontend TypeScript types to prevent type drift and ensure runtime safety.
Changes:
- Add openapi-typescript as dev dependency
- Create npm scripts for type generation (generate:types) and validation (validate:types)
- Integrate type generation into build pipeline (runs before TypeScript compilation)
- Generate frontend/src/types/generated.ts from backend OpenAPI schema
- Add frontend/scripts/validate-types.sh for CI/CD validation
- Update Web-Development.md with type generation workflow documentation
- Update Backend-Development.md with OpenAPI schema sync requirements
Workflow:
1. Backend automatically exposes OpenAPI schema at /api/openapi.json (FastAPI built-in)
2. Frontend build runs 'npm run generate:types' to generate types from schema
3. Generated types are committed to version control
4. CI can run 'npm run validate:types' to fail builds if types drift
Fixes critical type safety issue where frontend types were manually maintained
and could become out of sync with backend Pydantic models.

- 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.

This commit standardizes how API responses are wrapped, solving issue #24.
Problem:
- Inconsistent response envelopes (jails vs items vs bans vs no wrapper)
- Frontend required multiple field name variants
- Integration bugs from branching logic
- No clear pattern for different response types
Solution:
- Created response.py with base classes: PaginatedListResponse,
CollectionResponse, CommandResponse
- Standardized all list/collection responses to use 'items' field
- Domain-specific field names for detail and aggregation responses
- Updated all backends routers and mappers
- Updated frontend types and hooks to match
Changes:
Backend:
- backend/app/models/response.py (new): Base response models
- backend/app/models/ban.py: Updated responses to inherit from bases
- backend/app/models/jail.py: Updated JailListResponse, JailCommandResponse
- backend/app/models/config.py: Updated collection responses
- backend/app/services/jail_service.py: Updated return statements
- backend/app/mappers/ban_mappers.py: Updated 'bans' to 'items'
- backend/tests/test_mappers/test_ban_mappers.py: Updated tests
Frontend:
- frontend/src/types/jail.ts: Updated response interfaces
- frontend/src/types/config.ts: Updated response interfaces
- frontend/src/hooks/useActiveBans.ts: Updated selector
- frontend/src/hooks/useJailList.ts: Updated selector
- frontend/src/hooks/useJailConfigs.ts: Updated selector
- frontend/src/hooks/useConfigActiveStatus.ts: Updated field access
- frontend/src/hooks/useJailAdmin.ts: Updated field access
Documentation:
- Docs/Backend-Development.md: Added § 4.1 API Response Envelope Policy
The policy defines:
1. Paginated lists use PaginatedListResponse (items, total, page, page_size)
2. Non-paginated collections use CollectionResponse (items, total)
3. Detail responses use entity-specific field names (jail, status, settings)
4. Command responses use CommandResponse (message, success, optional target)
5. Aggregations use domain-specific fields (jails, countries, buckets, bans)
All responses now follow one of these patterns, reducing frontend complexity.

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

- 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.

Implement standardized skeleton loading placeholders to reduce perceived
loading time and prevent layout shift during data fetches. These components
match actual content dimensions exactly, improving perceived responsiveness.
New skeleton components in src/components/skeletons/:
- SkeletonTable: Table/grid loading with customizable rows and cells
- SkeletonTableRow: Individual animated skeleton row
- SkeletonChart: Chart/graph loading with bars matching dimensions
- SkeletonStat: Stat card loading with label and value
- SkeletonFormField: Form input loading placeholder
- PageLoadingSkeleton: Convenience wrapper for page-level loading states
Implementation details:
- All skeletons use global 'skeleton-pulse' animation (2s cycle)
- Dimensions match real content to prevent layout shift on arrival
- Marked with aria-hidden and role=presentation for accessibility
- Theme-aware colors using Fluent UI tokens
- Respects prefers-reduced-motion setting
Updates:
- ChartStateWrapper: Uses SkeletonChart instead of spinner
- PageFeedback: Added PageLoadingSkeleton component
- App.tsx: Injects skeleton styles at startup
- Web-Design.md: Added § 8a with loading UX guidance and usage examples
All components tested (22 tests, 100% passing) and linted.

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.

Eliminates ~100 lines of duplicated code across useListData and usePolledData
by creating a composable base hook that handles:
- Abort controller lifecycle and cancellation
- Loading/error state management
- Fetch error handling
- Unmount cleanup
Changes:
- Create hooks/useFetchData.ts with base fetch lifecycle (no effects on consumers)
- Refactor useListData to compose useFetchData, returns items array by default
- Refactor usePolledData to compose useFetchData, adds polling and focus-refetch
- Add comprehensive tests for useFetchData base hook
- Document hook architecture and composition pattern in Web-Development.md
Result: Both hooks now use shared primitives, reducing maintenance burden
and ensuring consistent cancellation/error handling across all data fetches.
