- Fix logfiles_router and thread_registry to resolve .rpt log files from Path(server["exe_path"]).parent/server/ instead of the languard data dir, which never contained log files — log list and live tail both now work correctly - Rewrite get_ui_schema() in config_generator to cover all ~80 fields across all 5 sections (server/basic/profile/launch/rcon) with proper toggle/select/number/password/tag-list/hidden widgets and labels; missions field is hidden (managed by Missions tab) - Add formatSelectDisplay() to ConfigEditor so select fields show descriptive text (e.g. "0 - Never") instead of raw numbers in view mode - Add ToggleDisplay for boolean fields (Enabled/Disabled with indicator dot) - Add section tab labels and descriptions to ConfigEditor - Add MissionList UX hints and dynamic Add/In Rotation button labels - Add "hidden" to FieldSchema widget union type - Update API.md, ARCHITECTURE.md, CLAUDE.md, FRONTEND.md, MODULES.md, THREADING.md to document log path fix and schema coverage

Key type notes:
Servertype inuseServers.tsusesgame_port,current_players,max_players(matches enriched API response)Missiontype:{ name, filename, size_bytes, terrain }— terrain parsed from filenameModtype:{ name, path, size_bytes, enabled, display_name, workshop_id }—display_name/workshop_idfrom mod.cpp/meta.cppBantype:{ id, server_id, guid, name, reason, banned_by, banned_at, expires_at, is_active, game_data }(matches API)- There is no REST endpoint for logs — logs are only pushed via WebSocket events
QueryClient defaults: staleTime: 10s, retry: 2, refetchOnWindowFocus: false.
Client State (Zustand)
auth.store.ts — Persisted to localStorage under languard-auth:
token: string | null— JWT access tokenuser: { id, username, role } | null— Current userisAuthenticated: boolean— Derived on rehydrationsetAuth(token, user)— Sets token, user, and writeslanguard_tokento localStorageclearAuth()— Clears all state and localStorage keys
ui.store.ts — In-memory only:
sidebarOpen: boolean— Sidebar collapse stateactiveServerId: number | null— Highlighted server in sidebarnotifications: Notification[]— Toast notifications (auto-remove after 5s)addNotification(type, message)— Add toast with auto-dismissremoveNotification(id)— Manual dismiss
API Client
src/lib/api.ts configures Axios with:
- Base URL:
VITE_API_URLenv var, defaults tohttp://localhost:8000 - Timeout: 30 seconds
- Request interceptor: Reads
languard_tokenfrom localStorage, addsAuthorization: Bearer <token>header - Response interceptor: On 401, checks if URL starts with
/api/auth/— if NOT an auth endpoint, clears token and redirects to/login. Auth endpoint 401s are left for the calling component to handle.
Standard response envelope: { success: boolean, data: T | null, error?: string }
WebSocket
useWebSocket.ts connects to VITE_WS_URL (default ws://localhost:8000):
- Accepts
UseWebSocketOptions(ornumber[]for backward compat):{ serverIds?, onEvent? } - Passes JWT token as query parameter:
/ws?token=...&server_id=... - Exponential backoff reconnect: starts 2s, doubles up to 30s max
- Close code 4001 = explicit disconnect (no reconnect)
onEventcallback: receives raw WebSocket events for custom handling (e.g., log accumulation in ServerDetailPage)- Event handlers invalidate TanStack Query caches:
server_status→["servers", id]+["servers"]metrics→["metrics", id]log→ no cache key (no REST endpoint for logs; use onEvent callback instead)players→["players", id]
Important: There is no REST endpoint for server logs. Logs are only available via WebSocket push events. Components that need log data must use the onEvent callback to accumulate log entries in local state, then pass them to LogViewer as props.
