No application logic is written here. -### 1.1 Initialise the backend project +### 1.1 Initialise the backend project ✅ -Create the `backend/` directory with the full folder structure defined in [Backend-Development.md § 3](Backend-Development.md). Set up `pyproject.toml` with all required dependencies (FastAPI, Pydantic v2, aiosqlite, aiohttp, APScheduler 4.x, structlog, pydantic-settings) and dev dependencies (pytest, pytest-asyncio, httpx, ruff, mypy). Configure ruff for 120-character line length and double-quote strings. Configure mypy in strict mode. Add a `.env.example` with placeholder keys for `BANGUI_DATABASE_PATH`, `BANGUI_FAIL2BAN_SOCKET`, and `BANGUI_SESSION_SECRET`.

Wire the theme into `App.tsx` via the `FluentProvider` `theme` prop. +**Done.** `frontend/src/theme/customTheme.ts` — BanGUI brand ramp centred on #0F6CBD (contrast ratio ≈ 5.4:1 against white, passes WCAG AA). Both `lightTheme` and `darkTheme` exported and wired into `App.tsx` via `FluentProvider`. -### 1.4 Create the central API client +### 1.4 Create the central API client ✅ -Build the typed API client in `frontend/src/api/client.ts`. It should be a thin wrapper around `fetch` that returns typed responses, includes credentials, and throws a custom `ApiError` on non-OK responses. Define the `BASE_URL` from `import.meta.env.VITE_API_URL` with a fallback to `"/api"`. Create `frontend/src/api/endpoints.ts` for path constants. See [Web-Development.md § 3](Web-Development.md) for the pattern. +**Done.** `frontend/src/api/client.ts` — typed `get`, `post`, `put`, `del` helpers, `ApiError` class with status and body, `BASE_URL` from `VITE_API_URL` env var. `frontend/src/api/endpoints.ts` — all backend path constants with typed factory helpers for dynamic segments. -### 1.5 Create the FastAPI application factory +### 1.5 Create the FastAPI application factory ✅ -Implement `backend/app/main.py` with the `create_app()` factory function. Register the async lifespan context manager that opens the aiosqlite database connection, creates a shared `aiohttp.ClientSession`, and initialises the APScheduler instance on startup, then closes all three on shutdown. Store these on `app.state`. Register a placeholder router so the app can start and respond to a health-check request. See [Backend-Development.md § 6](Backend-Development.md) and [Architekture.md § 2](Architekture.md) for details. +**Done.** `backend/app/main.py` — `create_app()` factory with async lifespan managing aiosqlite connection, `aiohttp.ClientSession`, and APScheduler. Settings stored on `app.state`. Health-check router registered. Unhandled exception handler logs errors and returns sanitised 500 responses. -### 1.6 Create the Pydantic settings model +### 1.6 Create the Pydantic settings model ✅ -Implement `backend/app/config.py` using pydantic-settings. Define the `Settings` class with fields for `database_path`, `fail2ban_socket`, `session_secret`, `session_duration_minutes`, and `timezone`. Load from environment variables prefixed `BANGUI_` and from `.env`. Validate at startup — the app must fail fast with a clear error if required values are missing. See [Backend-Development.md § 11](Backend-Development.md). +**Done.** `backend/app/config.py` — `Settings` class via pydantic-settings with all required fields, `BANGUI_` prefix, `.env` loading. `get_settings()` factory function. App fails fast with a `ValidationError` if required values are missing. -### 1.7 Set up the application database schema +### 1.7 Set up the application database schema ✅ -Design and create the SQLite schema for BanGUI's own data. The database needs tables for application settings (key-value pairs for master password hash, database path, fail2ban socket path, preferences), sessions (token, created-at, expires-at), blocklist sources (name, URL, enabled flag), and import log entries (timestamp, source URL, IPs imported, IPs skipped, errors). Write an initialisation function that creates these tables on first run via aiosqlite. This schema is for BanGUI's internal state — it does not replace the fail2ban database. See [Architekture.md § 2.2](Architekture.md) for the repository breakdown. +**Done.** `backend/app/db.py` — `init_db()` creates tables: `settings` (key-value config), `sessions` (auth tokens with expiry), `blocklist_sources` (name, URL, enabled), `import_log` (timestamp, source, counts, errors). WAL mode and foreign keys enabled. Function is idempotent — safe to call on every startup. -### 1.8 Write the fail2ban socket client wrapper +### 1.8 Write the fail2ban socket client wrapper ✅ -Implement `backend/app/utils/fail2ban_client.py` — an async wrapper around the fail2ban Unix domain socket protocol. Study `./fail2ban-master/fail2ban/client/csocket.py` and `./fail2ban-master/fail2ban/client/fail2banclient.py` to understand the wire protocol (pickle-based command/response). The wrapper should provide async methods for sending commands and receiving responses, handle connection errors gracefully, and log every interaction with structlog. This module is the single point of contact between BanGUI and the fail2ban daemon. See [Backend-Development.md § 2 (fail2ban Client Usage)](Backend-Development.md) and [Architekture.md § 2.2 (Utils)](Architekture.md). +**Done.** `backend/app/utils/fail2ban_client.py` — `Fail2BanClient` async class. Blocking socket I/O offloaded to thread-pool executor via `run_in_executor` so the event loop is never blocked. `send()` serialises commands to pickle, reads until `` marker, deserialises response. `ping()` helper. `Fail2BanConnectionError` and `Fail2BanProtocolError` custom exceptions.

All other features depend on these being complete. -### 2.1 Implement the setup service and repository +### 2.1 Implement the setup service and repository ✅ -Build `backend/app/services/setup_service.py` and `backend/app/repositories/settings_repo.py`. The setup service accepts the initial configuration (master password, database path, fail2ban socket path, general preferences), hashes the password with a secure algorithm (e.g. bcrypt or argon2), and persists everything through the settings repository. It must enforce the one-time-only rule: once a configuration is saved, setup cannot run again. Add a method to check whether setup has been completed (i.e. whether any configuration exists in the database). See [Features.md § 1](Features.md). +**Done.** `backend/app/repositories/settings_repo.py` — `get_setting`, `set_setting`, `delete_setting`, `get_all_settings` CRUD functions. `backend/app/repositories/session_repo.py` — `create_session`, `get_session`, `delete_session`, `delete_expired_sessions`. `backend/app/services/setup_service.py` — `run_setup()` hashes the master password with bcrypt (auto-generated salt), persists all settings, enforces one-time-only by writing `setup_completed=1` last. `is_setup_complete()` and `get_password_hash()` helpers. -### 2.2 Implement the setup router +### 2.2 Implement the setup router ✅ -Create `backend/app/routers/setup.py` with a `POST /api/setup` endpoint that accepts a Pydantic request model containing all setup fields and delegates to the setup service. If setup has already been completed, return a `409 Conflict`. Define request and response models in `backend/app/models/setup.py`. +**Done.** `backend/app/routers/setup.py` — `GET /api/setup` returns `SetupStatusResponse`. `POST /api/setup` accepts `SetupRequest`, returns 201 on first call and 409 on subsequent calls. Registered in `create_app()`. -### 2.3 Implement the setup-redirect middleware +### 2.3 Implement the setup-redirect middleware ✅ -Add middleware to the FastAPI app that checks on every incoming request whether setup has been completed. If not, redirect all requests (except those to `/api/setup` itself) to `/api/setup` with a `307 Temporary Redirect` or return a `403` with a clear message. Once setup is done, the middleware becomes a no-op. See [Features.md § 1](Features.md). +**Done.** `SetupRedirectMiddleware` in `backend/app/main.py` — checks `is_setup_complete(db)` on every `/api/*` request (except `/api/setup` and `/api/health`). Returns `307 → /api/setup` when setup has not been completed. No-op after first run. -### 2.4 Implement the authentication service +### 2.4 Implement the authentication service ✅ -Build `backend/app/services/auth_service.py`. It must verify the master password against the stored hash, create session tokens on successful login, store sessions through `backend/app/repositories/session_repo.py`, validate tokens on every subsequent request, and enforce session expiry. Sessions should be stored in the SQLite database so they survive server restarts. See [Features.md § 2](Features.md) and [Architekture.md § 2.2](Architekture.md). +**Done.** `backend/app/services/auth_service.py` — `login()` verifies password with `bcrypt.checkpw`, generates a 64-char hex session token with `secrets.token_hex(32)`, stores the session via `session_repo`. `validate_session()` checks the DB and enforces expiry by comparing ISO timestamps. `logout()` deletes the session row. -### 2.5 Implement the auth router +### 2.5 Implement the auth router ✅ -Create `backend/app/routers/auth.py` with two endpoints: `POST /api/auth/login` (accepts a password, returns a session token or sets a cookie) and `POST /api/auth/logout` (invalidates the session). Define request and response models in `backend/app/models/auth.py`. +**Done.** `backend/app/routers/auth.py` — `POST /api/auth/login` verifies password, returns `LoginResponse` with token + expiry, sets `HttpOnly SameSite=Lax bangui_session` cookie. `POST /api/auth/logout` reads token from cookie or Bearer header, calls `auth_service.logout()`, clears the cookie. Both endpoints registered in `create_app()`. -### 2.6 Implement the auth dependency +### 2.6 Implement the auth dependency ✅ -Create a FastAPI dependency in `backend/app/dependencies.py` that extracts the session token from the request (cookie or header), validates it through the auth service, and either returns the authenticated session or raises a `401 Unauthorized`. Every protected router must declare this dependency. See [Backend-Development.md § 4](Backend-Development.md) for the Depends pattern. +**Done.** `require_auth` dependency added to `backend/app/dependencies.py` — extracts token from cookie or `Authorization: Bearer` header, calls `auth_service.validate_session()`, raises 401 on missing/invalid/expired token. `AuthDep = Annotated[Session, Depends(require_auth)]` type alias exported for router use. -### 2.7 Build the setup page (frontend) +### 2.7 Build the setup page (frontend) ✅ -Create `frontend/src/pages/SetupPage.tsx`. The page should present a form with fields for the master password (with confirmation), database path, fail2ban socket path, and general preferences (timezone, date format, session duration). Use Fluent UI form components (`Input`, `Button`, `Field`, `Dropdown` for timezone). On submission, call `POST /api/setup` through the API client. Show validation errors inline. After successful setup, redirect to the login page. Create the corresponding API function in `frontend/src/api/setup.ts` and types in `frontend/src/types/setup.ts`. See [Features.md § 1](Features.md) and [Web-Design.md § 8](Web-Design.md) for component choices. +**Done.** `frontend/src/pages/SetupPage.tsx` — Fluent UI v9 form with `Field`/`Input` for master password (+ confirm), database path, fail2ban socket, timezone, session duration. Client-side validation before submit. Calls `POST /api/setup` via `frontend/src/api/setup.ts`. Redirects to `/login` on success. `frontend/src/types/setup.ts` typed interfaces. -### 2.8 Build the login page (frontend) +### 2.8 Build the login page (frontend) ✅ -Create `frontend/src/pages/LoginPage.tsx`. A single password input and a submit button — no username field. On submission, call `POST /api/auth/login`. On success, store the session (cookie or context) and redirect to the originally requested page or the dashboard. Show an error message on wrong password. Create `frontend/src/api/auth.ts` and `frontend/src/types/auth.ts`. See [Features.md § 2](Features.md). +**Done.** `frontend/src/pages/LoginPage.tsx` — single password field, submit button, `ApiError` 401 mapped to human-readable message. After login calls `useAuth().login()` and navigates to `?next=` or `/`. `frontend/src/api/auth.ts` and `frontend/src/types/auth.ts` created. -### 2.9 Implement the auth context and route guard +### 2.9 Implement the auth context and route guard ✅ -Create `frontend/src/providers/AuthProvider.tsx` that manages authentication state (logged in / not logged in) and exposes login, logout, and session-check methods via React context. Create a route guard component that wraps all protected routes: if the user is not authenticated, redirect to the login page and remember the intended destination. After login, redirect back. See [Features.md § 2](Features.md) and [Web-Development.md § 7](Web-Development.md). +**Done.** `frontend/src/providers/AuthProvider.tsx` — React context with `isAuthenticated`, `login()`, `logout()`. Session token and expiry stored in `sessionStorage`. `useAuth()` hook exported. `frontend/src/components/RequireAuth.tsx` — wraps protected routes; redirects to `/login?next=` when unauthenticated. `App.tsx` updated with full route tree: `/setup`, `/login`, `/` (guarded), `*` → redirect. -### 2.10 Write tests for setup and auth +### 2.10 Write tests for setup and auth ✅ -Write backend tests covering: setup endpoint accepts valid data, setup endpoint rejects a second call, login succeeds with correct password, login fails with wrong password, protected endpoints reject unauthenticated requests, logout invalidates the session for both router and service. Use pytest-asyncio and httpx `AsyncClient` as described in [Backend-Development.md § 9](Backend-Development.md). +**Done.** 85 total tests pass. New tests cover: setup status endpoint, POST /api/setup (valid payload, short password rejection, second-call 409, defaults), setup-redirect middleware (pre-setup redirect, health bypass, post-setup access), login success/failure/cookie, logout (200, cookie cleared, idempotent, session invalidated), auth service (login, wrong password, session persistence, validate, logout), settings repo (CRUD round-trips), session repo (create/get/delete/cleanup expired). ruff 0 errors, mypy --strict 0 errors. --- diff --git a/backend/app/dependencies.py b/backend/app/dependencies.py index ebb8fd4..39bf9cc 100644 --- a/backend/app/dependencies.py +++ b/backend/app/dependencies.py @@ -13,9 +13,12 @@ import structlog from fastapi import Depends, HTTPException, Request, status from app.config import Settings +from app.models.auth import Session log: structlog.stdlib.BoundLogger = structlog.get_logger() +_COOKIE_NAME = "bangui_session" + async def get_db(request: Request) -> aiosqlite.Connection: """Provide the shared :class:`aiosqlite.Connection` from ``app.state``. @@ -51,6 +54,51 @@ async def get_settings(request: Request) -> Settings: return request.app.state.settings # type: ignore[no-any-return] +async def require_auth( + request: Request, + db: Annotated[aiosqlite.Connection, Depends(get_db)], +) -> Session: + """Validate the session token and return the active session. + + The token is read from the ``bangui_session`` cookie or the + ``Authorization: Bearer`` header. + + Args: + request: The incoming FastAPI request. + db: Injected aiosqlite connection. + + Returns: + The active :class:`~app.models.auth.Session`. + + Raises: + HTTPException: 401 if no valid session token is found. + """ + from app.services import auth_service # noqa: PLC0415 + + token: str | None = request.cookies.get(_COOKIE_NAME) + if not token: + auth_header: str = request.headers.get("Authorization", "") + if auth_header.startswith("Bearer "): + token = auth_header[len("Bearer "):] + + if not token: + raise HTTPException( + status_code=status.HTTP_401_UNAUTHORIZED, + detail="Authentication required.", + headers={"WWW-Authenticate": "Bearer"}, + ) + + try: + return await auth_service.validate_session(db, token) + except ValueError as exc: + raise HTTPException( + status_code=status.HTTP_401_UNAUTHORIZED, + detail=str(exc), + headers={"WWW-Authenticate": "Bearer"}, + ) from exc + + # Convenience type aliases for route signatures.

The fail2ban SQLite database stores ban records — read them using aiosqlite (open the fail2ban DB path from settings, read-only). Return structured ban objects including IP, jail, timestamp, and any additional metadata available. See [Features.md § 3 (Ban List)](Features.md). +**Done.** `backend/app/services/ban_service.py` — `list_bans()` and `list_accesses()` open the fail2ban SQLite DB read-only via aiosqlite (`file:{path}?mode=ro`). DB path is resolved by sending `["get", "dbfile"]` to the fail2ban Unix socket. Both functions accept `TimeRange` preset (`24h`, `7d`, `30d`, `365d`), page/page_size pagination, and an optional async geo-enricher callable. Returns `DashboardBanListResponse` / `AccessListResponse` Pydantic models. `_parse_data_json()` extracts `matches` list and `failures` count from the `data` JSON column. -### 5.2 Implement the geo service +### 5.2 Implement the geo service ✅ -Build `backend/app/services/geo_service.py`. Given an IP address, resolve its country of origin (and optionally ASN and RIR). Use an external API via aiohttp or a local GeoIP database. Cache results to avoid repeated lookups for the same IP. The geo service is used throughout the application wherever country information is displayed. See [Features.md § 5 (IP Lookup)](Features.md) and [Architekture.md § 2.2](Architekture.md). +**Done.** `backend/app/services/geo_service.py` — `lookup(ip, http_session)` calls `http://ip-api.com/json/{ip}?fields=status,message,country,countryCode,org,as`. Returns `GeoInfo` dataclass (`country_code`, `country_name`, `asn`, `org`). Results are cached in a module-level `_cache` dict (max 10,000 entries, evicted by clearing the whole cache on overflow). Negative results (`status=fail`) are also cached. Network failures return `None` without caching. `clear_cache()` exposed for tests. -### 5.3 Implement the dashboard bans endpoint +### 5.3 Implement the dashboard bans endpoint ✅ -Add `GET /api/dashboard/bans` to `backend/app/routers/dashboard.py`. It accepts a time-range query parameter (hours or a preset like `24h`, `7d`, `30d`, `365d`). It calls the ban service to retrieve bans in that window, enriches each ban with country data from the geo service, and returns a paginated list. Define request/response models in `backend/app/models/ban.py`. +**Done.** Added `GET /api/dashboard/bans` and `GET /api/dashboard/accesses` to `backend/app/routers/dashboard.py`. Both accept `range` (`TimeRange`, default `24h`), `page` (default `1`), and `page_size` (default `100`) query parameters. Each endpoint reads `fail2ban_socket` from `app.state.settings` and `http_session` from `app.state`, creates a `geo_service.lookup` closure, and delegates to `ban_service`.

Above the table, place a time-range selector implemented as a `Toolbar` with `ToggleButton` for the four presets (24 h, 7 d, 30 d, 365 d). Create a `useBans` hook that calls `GET /api/dashboard/bans` with the selected range. See [Features.md § 3 (Ban List)](Features.md) and [Web-Design.md § 8 (Data Display)](Web-Design.md). +**Done.** `frontend/src/components/BanTable.tsx` — Fluent UI v9 `DataGrid` with two modes (`"bans"` / `"accesses"`). Bans columns: Time of Ban, IP Address (monospace), Service (URL from matches, truncated with Tooltip), Country, Jail, Bans (Badge coloured by count: danger >5, warning >1). Accesses columns: Timestamp, IP Address, Log Line (truncated with Tooltip), Country, Jail. Loading → ``, Error → ``, Empty → informational text. Pagination buttons. `useBans` hook (`frontend/src/hooks/useBans.ts`) fetches `GET /api/dashboard/bans` or `/api/dashboard/accesses`; resets page on mode/range change. -### 5.5 Build the dashboard page +### 5.5 Build the dashboard page ✅ -Create `frontend/src/pages/DashboardPage.tsx`. Compose the server status bar at the top, then a `Pivot` (tab control) switching between "Ban List" and "Access List". The Ban List tab renders the `BanTable`. The Access List tab uses the same table component but fetches all recorded accesses, not just bans. If the access list requires a separate endpoint, add `GET /api/dashboard/accesses` to the backend with the same time-range support.

New `backend/app/models/geo.py` with `GeoDetail` and `IpLookupResponse`. All three routers registered in `main.py`. -Add to `backend/app/routers/bans.py`: -- `POST /api/bans` — ban an IP in a specified jail. Validate the IP with `ipaddress` before sending. -- `DELETE /api/bans` — unban an IP from a specific jail or all jails. Support an `unban_all` flag. -- `GET /api/bans/active` — list all currently banned IPs across all jails, with jail name, ban start time, expiry, and ban count. +### 6.4 Build the jail overview page (frontend) ✅ -Delegate to the ban service. See [Features.md § 5 (Ban an IP, Unban an IP, Currently Banned IPs)](Features.md). +**Done.** `frontend/src/pages/JailsPage.tsx` fully implemented. Four sections: Jail Overview DataGrid with start/stop/idle/reload controls, Ban/Unban IP form, Currently Banned IPs table with unban buttons, and IP Lookup. Types in `frontend/src/types/jail.ts`. API module at `frontend/src/api/jails.ts`. Hooks (`useJails`, `useActiveBans`, `useIpLookup`) in `frontend/src/hooks/useJails.ts`. -### 6.4 Build the jail overview page (frontend) +### 6.5 Build the jail detail page (frontend) ✅ -Create `frontend/src/pages/JailsPage.tsx`. Display a card or table for each jail showing name, status badge (running/stopped/idle), backend type, banned count, total bans, failure counts, find time, ban time, and max retries. Each jail links to a detail view. Use Fluent UI `Card` or `DataGrid`. Create `frontend/src/api/jails.ts`, `frontend/src/types/jail.ts`, and a `useJails` hook. See [Features.md § 5 (Jail Overview)](Features.md). +**Done.** `frontend/src/pages/JailDetailPage.tsx` fully implemented. Displays jail status badges with Start/Stop/Idle/Resume/Reload controls, live stats grid, log paths, fail-regex, ignore-regex, date pattern, encoding, and actions list in monospace. Breadcrumb navigation back to the jails list. -### 6.5 Build the jail detail page (frontend) +### 6.6 Build the ban/unban UI (frontend) ✅ -Create `frontend/src/pages/JailDetailPage.tsx` — reached via `/jails/:name`. Fetch the full jail detail and display: monitored log paths, fail regex and ignore regex lists (rendered in monospace), date pattern, log encoding, attached actions and their config, and ban-time escalation settings. Include control buttons (Start, Stop, Idle, Reload) that call the corresponding API endpoints with confirmation dialogs (Fluent UI `Dialog`). See [Features.md § 5 (Jail Detail, Jail Controls)](Features.md). +**Done.** Ban/Unban form on JailsPage with IP input, jail selector, "Unban" and "Unban from All Jails" buttons. "Currently Banned IPs" DataGrid with per-row unban button, country, ban timing, and repeat-offender badge. MessageBar feedback on success/error. -### 6.6 Build the ban/unban UI (frontend) +### 6.7 Implement IP lookup endpoint and UI ✅ -On the Jails page (or a dedicated sub-section), add a "Ban an IP" form with an IP input field and a jail selector dropdown. Add an "Unban an IP" form with an IP input (or selection from the currently-banned list), a jail selector (or "all jails"), and an "unban all" option. Show success/error feedback using Fluent UI `MessageBar` or `Toast`. Build a "Currently Banned IPs" table showing IP, jail, ban start, expiry, ban count, and a direct unban button per row. See [Features.md § 5 (Ban an IP, Unban an IP, Currently Banned IPs)](Features.md). +**Done.** `GET /api/geo/lookup/{ip}` returns currently-banned jails and geo info. IP Lookup section on JailsPage shows ban status badges and geo details (country, org, ASN). -### 6.7 Implement IP lookup endpoint and UI +### 6.8 Implement the ignore list (whitelist) endpoints and UI ✅ -Add `GET /api/geo/lookup/{ip}` to `backend/app/routers/geo.py`. The endpoint checks whether the IP is currently banned (and in which jails), retrieves its ban history (count, timestamps, jails), and fetches enriched info (country, ASN, RIR) from the geo service. On the frontend, create an IP Lookup section in the Jails area where the user can enter any IP and see all this information. See [Features.md § 5 (IP Lookup)](Features.md). +**Done.** All ignore-list endpoints implemented in the jails router. "Ignore List (IP Whitelist)" section on the JailDetailPage with add-by-input form, per-entry remove button, and `ignore self` badge. -### 6.8 Implement the ignore list (whitelist) endpoints and UI +### 6.9 Write tests for jail and ban features ✅ -Add endpoints to `backend/app/routers/jails.py` for managing ignore lists: -- `GET /api/jails/{name}/ignoreip` — get the ignore list for a jail. -- `POST /api/jails/{name}/ignoreip` — add an IP or network to a jail's ignore list. -- `DELETE /api/jails/{name}/ignoreip` — remove an IP from the ignore list. -- `POST /api/jails/{name}/ignoreself` — toggle the "ignore self" option. - -On the frontend, add an "IP Whitelist" section to the jail detail page showing the ignore list with add/remove controls. See [Features.md § 5 (IP Whitelist)](Features.md). - -### 6.9 Write tests for jail and ban features - -Test jail listing with mocked socket responses, jail detail parsing, start/stop/reload commands, ban and unban execution, currently-banned list retrieval, IP lookup with and without ban history, and ignore list operations. Ensure all socket interactions are mocked. +**Done.** `backend/tests/test_services/test_jail_service.py` — 40 tests covering list, detail, controls, ban/unban, active bans, ignore list, and IP lookup. `backend/tests/test_routers/test_jails.py`, `test_bans.py`, `test_geo.py` — 36 router tests.

It reads the active fail2ban configuration by querying the daemon for jail settings, filter regex patterns, and global parameters. It also writes configuration changes by sending the appropriate set commands through the socket (or by editing config files and triggering a reload, depending on what fail2ban supports for each setting). The service must validate regex patterns before applying them — attempting to compile each pattern and returning a clear error if it is invalid.

In-process regex validation via the `re` module with `ConfigValidationError` on failure. `test_regex` is synchronous/pure-Python (no socket). `preview_log` reads file tail via `_read_tail_lines` (executor) and pattern-tests each line.

Provide inline editing: clicking a value turns it into an editable field. Add/remove buttons for regex patterns. A "Save" button persists changes and optionally triggers a reload. Show validation errors inline. Use Fluent UI `Accordion`, `Input`, `Textarea`, `Switch`, and `Button`.
