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)

Moved all static layout properties (display, gap, margin, padding, colour)
from inline style props to makeStyles classes in:
- MapBansTable.tsx: Pagination row flexbox layout
- JailDetailPage.tsx: Link styling for textDecoration
- HistoryPage.tsx: Summary text styling
- IpDetailView.tsx: Loading container and text formatting
Kept inline styles only for genuinely dynamic values:
- WorldMap.tsx: Tooltip position (follows mouse)
- TopCountriesPieChart.tsx: Legend color (from recharts data)
- TopCountriesBarChart.tsx: Chart height (derives from data length)
This change improves performance by leveraging Griffel's atomic CSS cache
and ensures consistency with the established Fluent UI pattern.
Updated Docs/Web-Development.md with explicit rule: inline styles only
for runtime-dynamic values, all static properties go in makeStyles.

Create useBansByCountry as the shared base hook containing all common
fetch logic, abort-controller pattern, and state management. Both
useDashboardCountryData and useMapData now wrap this base hook:
- useDashboardCountryData: Thin wrapper that calls base hook with autoFetch=true
- useMapData: Wraps base hook with 300ms debounce layer
Changes:
- Create useBansByCountry.ts (base hook with optional autoFetch parameter)
- Refactor useDashboardCountryData.ts to use base hook
- Refactor useMapData.ts to use base hook with debounce wrapper
- Add tests for all three hooks
Benefits:
- Single source of truth for ban-by-country logic
- Bug fixes in base hook apply to both consumers
- Eliminates code duplication (~80 lines reduced)
- Maintains backward compatibility: existing call sites work unchanged

Move reusable UI section components (JailInfoSection, PatternsSection,
BantimeEscalationSection, IgnoreListSection, CodeList) from pages/jail/
to components/jail/, aligning with the project convention that pages/
contains only route-level entry points while components/ contains reusable
UI building blocks.
Changes:
- Move 5 section components + jailDetailPageStyles.ts to components/jail/
- Update import paths in moved components (relative paths to commonStyles)
- Update JailDetailPage.tsx imports to reference components/jail/
- Delete empty pages/jail/ directory
- Document pages/ vs components/ distinction in Web-Development.md
All components use standard import structure and TypeScript passes type
checking. BannedIpsSection was already correctly placed in components/jail/.

- Split monolithic useJailDetail hook into separate concerns
- Created useJailData for fetching and managing jail data
- Created useJailCommands for jail operations (power, console, etc.)
- Updated JailDetailPage to use new hooks
- Updated tests to reflect new hook structure
- Removed old useJailDetail hook

- Refactor useJails (useJailList.ts) to use useListData with onSuccess for total
- Refactor useBanTrend to use useListData with onSuccess for bucket_size
- Refactor useDashboardCountryData to use useListData with onSuccess for aggregated data
- Refactor useHistory to use useListData with proper abort guard in finally()
- Create usePolledData for single-item endpoints with polling and window focus refetch
- Refactor useServerStatus to use usePolledData for 30s polling + window focus refetch
- Keep useIpHistory with manual pattern (single-item, no list semantics)
- Document deferred refactoring of useJailDetail (depends on T-13 for data/command split)
All data-fetching hooks now follow one of two consistent patterns:
1. useListData: for paginated/list endpoints with refresh semantics
2. usePolledData: for single-item endpoints with polling and focus-refetch
This eliminates code duplication, centralizes abort-guard logic, and enables
consistent fixes across all data-fetching hooks.
Resolves T-12.

Problem: Repository modules use structural typing to satisfy Protocol interfaces via
cast(). A function rename, parameter change, or signature mismatch would silently pass
mypy but fail at runtime.
Solution (Option B — minimal):
1. Aligned Protocol signatures in protocols.py with actual implementations:
- BlocklistRepository: dict[str, object] → dict[str, Any] (matches implementation)
- ImportLogRepository: dict[str, object] → ImportLogRow (typed model)
- GeoCacheRepository: dict[str, object] → GeoCacheRow; Iterable → Sequence
- HistoryArchiveRepository: dict[str, object] → dict[str, Any]
- ImportLogRepository: async compute_total_pages → sync (matches implementation)
2. Created CI validation script (backend/scripts/validate_repository_protocols.py)
that runs at build time to ensure all repository modules satisfy their Protocol
interfaces. Exit 0 if valid, 1 if any mismatch. Detects:
- Missing functions
- Parameter count mismatches
- Type annotation mismatches
- Return type mismatches
3. Updated backend/app/dependencies.py with explicit docstrings linking each
get_*_repo() provider to Backend-Development.md § 13.7.1, explaining the
module-as-Protocol pattern and that it is intentional and validated.
4. Documented the pattern in Backend-Development.md § 13.7.1:
'Repository Module Pattern — Module-as-Protocol Structural Compatibility'
explaining why the pattern works, risks (silent breakage), and how the
validation mitigates it.
5. Fixed type annotation in history_archive_repo.py:
- get_all_archived_history returns list[dict] → list[dict[str, Any]]
- Imported Any type
Benefits:
- Prevents silent breakage of repository interfaces
- Formalizes the module-as-Protocol pattern as intentional
- CI validation prevents regressions without refactoring cost
- All repository tests pass (53/53)
- mypy --strict passes on modified files

Instead of returning a bound method (geo_cache.lookup_batch), now inject
the GeoCache instance directly into routers and services. This provides
proper runtime isolation since T-04 made GeoCache a proper object.
Changes:
- Remove get_geo_batch_lookup() dependency provider
- Add GeoCacheDep type alias for injecting GeoCache instances
- Update all routers (bans, blocklist, dashboard, jails) to use GeoCacheDep
- Update ban_service, blocklist_service, jail_service to accept GeoCache
- Update service protocols to match new signatures
- Update docstrings to reference GeoCache methods instead of module functions
All callers now call geo_cache.lookup_batch(...) directly instead of
geo_batch_lookup(...), providing real dependency injection with proper
testing isolation.

Create GeoCache class with all mutable state as instance attributes:
- _cache, _neg_cache, _dirty, _geoip_reader, _geoip_initialized, _cache_lock
- All public methods: lookup(), lookup_batch(), lookup_cached_only(), flush_dirty(), load_from_db(), clear(), etc.
Initialization & Dependency Injection:
- Instantiate GeoCache in startup.py and store on app.state.geo_cache
- Add get_geo_cache() dependency function in dependencies.py
- Inject into routes and tasks via FastAPI's dependency system
Backward Compatibility:
- Maintain module-level functions in geo_service.py as deprecated wrappers
- All old callers continue to work through _default_geo_cache instance
- Remove test-escape-hatch functions (clear_cache, clear_neg_cache moved to methods)
Background Tasks:
- Update geo_cache_flush.py and geo_re_resolve.py to receive GeoCache instance
- Tasks now operate on injected instance rather than module globals
Tests:
- Refactor test_geo_service.py with geo_cache fixture providing fresh instances
- Update patch paths to target GeoCache methods correctly
- Fix internal state assertions to access instance attributes
Documentation:
- Update Architekture.md to document GeoCache as managed stateful service
- Describe cache lifecycle (load on startup, flush periodically, re-resolve stale)
- Note process-local limitations for multi-worker deployments
Fixes violation of Single Responsibility Principle: module no longer owns both
lookup logic and cache lifecycle management. Cache is now a first-class
injectable service with transparent lifecycle.

When save() encounters a 401 or 403 error, the HTTP client dispatches
SESSION_EXPIRED_EVENT which triggers auth handling and navigation to login.
However, setSaveError was called first, causing a brief flash of an
'Unauthorized' message before the redirect.
Now, isAuthError(err) checks if the error is a 401/403 before setting
saveError. Auth errors are rethrown without setting error state, allowing
the auth handler to deal with session expiry cleanly without UX confusion.
- Import isAuthError from api/client in useConfigItem hook
- Check for auth errors in the save() catch block before setSaveError
- Add tests for 401 and 403 error handling

Replace the flawed join-based comparison (entryKeys.join(',')) with
JSON.stringify() to properly handle keys containing commas. The previous
implementation could produce false equality when different key sets
shared the same comma-separated representation (e.g., 'a,b' key vs
separate 'a' and 'b' keys).
This ensures the effect fires correctly when keys change, fixing silent
failures to update derived state.

- 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

Previously, the withRefresh helper and all operations (startJail, stopJail, setIdle, reloadJail, reloadAll) were recreated on every render because they were defined in the hook body without useCallback. This caused unnecessary re-renders of child components using React.memo when parent state changed.
Now each operation is wrapped in useCallback with [load] as its dependency. This ensures function references remain stable between renders, allowing React.memo optimizations to work correctly in JailOverviewSection.
Tests confirm that function references are now stable between consecutive renders.

TASK-ABORT-03: Fix stale abortRef read in .finally() callbacks
In useGlobalConfig, useServerSettings, and useJailConfigDetail hooks, the
.finally() block was reading abortRef.current instead of using the locally
captured controller reference. If load() is called while a fetch is in flight,
the previous fetch's .finally() would read the new controller (not aborted)
and prematurely clear the loading state while the new fetch is still pending.
Changes:
- useGlobalConfig.ts: use locally-captured ctrl in .finally() (line 46)
- useServerSettings.ts: use locally-captured ctrl in .finally() (line 50)
- useJailConfigDetail.ts: use locally-captured ctrl in .finally() (line 47)
All three hooks already use ctrl correctly in .then() and .catch() callbacks.
Documentation:
- Add 'AbortController in Hooks' section to Web-Development.md
- Explains the pattern and shows incorrect vs correct examples
- Prevents future regressions

Add optional signal?: AbortSignal parameter to all API GET functions so they can be
cancelled when components unmount. This prevents state-update warnings and wasted
resources.
Changes:
- frontend/src/api/history.ts: fetchHistory, fetchIpHistory
- frontend/src/api/map.ts: fetchBansByCountry
- frontend/src/api/jails.ts: fetchJails, fetchActiveBans
- frontend/src/api/config.ts: fetchJailConfig, fetchInactiveJails, fetchJailConfigFiles,
fetchFilterFiles (threads signal through fetchFilters), fetchFilterFile, fetchActionFiles,
fetchActionFile
- frontend/src/api/blocklist.ts: fetchImportLog, previewBlocklist
Updated all calling hooks to pass the abort signal from their controllers:
- useHistory, useIpHistory
- useMapData
- useActiveBans
- useJails
- useConfigActiveStatus (fetchJails and fetchJailConfigs)
- useJailAdmin (fetchInactiveJails)
- useJailConfigDetail (fetchJailConfig)
- useImportLog (fetchImportLog)
- useBlocklists (previewBlocklist with AbortController)
Updated Docs/Web-Development.md to document the convention.

Refactored AssignActionDialog and AssignFilterDialog to only render
dialog content when open=true. This prevents useJails() from being called
when dialogs are closed, eliminating unnecessary GET /api/jails requests.
Implementation uses inner components (AssignActionDialogInner,
AssignFilterDialogInner) that are only mounted when the dialog is open.
The Dialog wrapper remains in the outer component to preserve Fluent UI
animation behavior.
Fixed test setup for AssignFilterDialog to properly call
assignFilterToJail from the mocked onAssign callback.
Fixes TASK-BUG-08.

When useJailConfigs performs a background refresh, it may deliver an updated
JailConfig object for an already-selected jail. Previously, JailConfigDetail
would continue displaying stale locally-edited form values because the component
only re-initialized on jail name changes (via the key prop), not on object
identity changes.
Added a useEffect that detects when the jail prop reference has changed
(indicating a server refresh) and automatically resets all form fields to the
new server state, but only if autoSave is idle and has no pending changes.
This prevents accidentally overwriting external changes when the user saves,
while still letting users continue editing unsaved changes without interruption.
The implementation:
- Tracks the last-synced jail object in a ref
- Compares incoming jail reference to detect server updates
- Checks autoSave status to ensure no pending saves
- Verifies that current form state matches the old jail values
- Resets all 20+ form fields when conditions are met

Previously, the tab content wrapper used 'key={tab}' which caused React to
unmount and remount the entire subtree when switching tabs. This destroyed
all component state, including unsaved form data and pending auto-saves.
Changes:
- Removed 'key={tab}' from the wrapper div
- All tab panels now render at page initialization
- Inactive tabs use CSS 'display: none' to hide without unmounting
- Tabs remain mounted throughout the page lifetime
- Users can now switch tabs without losing form input
Updated ConfigPage.test.tsx to reflect that inactive tabs remain in the DOM
(just hidden with CSS) rather than being removed entirely.
Documentation: Added 'Tab Panels' section to Web-Development.md
explaining the rule and rationale.

The hook was passing an inline onSuccess callback to useListData, which
included onSuccess in its internal refresh function's dependency array.
This caused refresh to be recreated on each render, which triggered the
useEffect, which fired the fetch, which completed and caused a re-render,
creating an infinite loop.
Wrap onSuccess in useCallback with empty dependencies so it maintains a
stable reference across renders. This allows refresh to be stable when
its dependencies don't change, breaking the cycle.
Add documentation to Refactoring.md explaining the onSuccess stability
requirement for useListData callers.
Also add tests for useJailConfigs to verify it doesn't trigger infinite
refetches with stable onSuccess callback.
