# Languard Server Manager

## Quick Start

```bash
# Backend (from backend/)
python -m uvicorn main:app --host 0.0.0.0 --port 8000 --reload

# Frontend (from frontend/)
npx vite --host
```

- Backend API: http://localhost:8000 (docs: http://localhost:8000/docs)
- Frontend: http://localhost:5173
- Default admin: `admin` / (random, printed at first startup; reset via `python -c "from core.auth.utils import hash_password; print(hash_password('admin123'))"` then update SQLite)

## Architecture

FastAPI + SQLite backend, React 19 + TypeScript + Vite frontend. See ARCHITECTURE.md for full details.

### Key Rules
- Frontend types must match API response shapes, NOT database schema columns
- There is no REST endpoint for logs — logs are only pushed via WebSocket events
- WebSocket `onEvent` callback is the mechanism for receiving real-time log entries
- Config updates use optimistic locking (config_version) — 409 on conflict
- Sensitive config fields are encrypted at rest with Fernet

## Current Implementation Status

### Backend: Fully implemented (42+ endpoints)
All routers, services, repositories, game adapter system, WebSocket, background threads, and scheduled cleanup are complete.

### Frontend: Fully implemented (baseline)

| Route | Status | Notes |
|-------|--------|-------|
| `/login` | Complete | Zod + react-hook-form validation |
| `/` | Complete | Dashboard with server grid + Start/Stop/Restart quick actions |
| `/servers/:id` | Complete | 7-tab detail page (overview, config, players, bans, missions, mods, logs) |
| `/servers/new` | Complete | 4-step wizard with per-step validation via `trigger()` |
| `/settings` | Complete | Password change + admin user management |

### Frontend Type Mapping (API → Frontend)

Types below reflect the **current** API shape. Fields marked `(planned)` will be added during the UX enhancement plan.

| API Resource | Frontend Type | Key Fields |
|---|---|---|
| Server (enriched) | `Server` in useServers.ts | `game_port`, `current_players`, `max_players`, `cpu_percent`, `ram_mb` |
| Mission | `Mission` in useServerDetail.ts | `name`, `filename`, `size_bytes`, `terrain` *(planned)* |
| Mod | `Mod` in useServerDetail.ts | `name`, `path`, `size_bytes`, `enabled`, `display_name` *(planned)*, `workshop_id` *(planned)* |
| Ban | `Ban` in useServerDetail.ts | `id`, `server_id`, `guid`, `name`, `reason`, `banned_by`, `banned_at`, `expires_at`, `is_active`, `game_data` |
| Player | `Player` in useServerDetail.ts | `id`, `slot_id`, `name`, `guid`, `ip`, `ping` |

### Upcoming: UX Enhancement Plan

**Plan file:** `.claude/plan/arma3-ux-enhancement.md` — approved, ready to implement.

| Phase | Feature | Status |
|-------|---------|--------|
| 1 | Config field UI widgets (textarea/toggle/select/tag-list per field) | Pending |
| 2 | Mission rotation table + multi-file upload | Pending |
| 3 | Mod display names (mod.cpp) + split-pane selector | Pending |
| 4 | Player Kick/Ban from Players tab via RCon | Pending |
| 5 | Historical log file browser + live log level filter | Pending |

**New endpoints added by the plan:**
- `GET /api/servers/{id}/config/schema` — per-field widget hints
- `GET|PUT /api/servers/{id}/missions/rotation` — mission rotation
- `POST /api/servers/{id}/players/{slot_id}/kick`
- `POST /api/servers/{id}/players/{slot_id}/ban`
- `GET /api/servers/{id}/logfiles`
- `GET /api/servers/{id}/logfiles/{filename}/download`
- `DELETE /api/servers/{id}/logfiles/{filename}`

**New backend additions:**
- `Arma3ConfigGenerator.get_ui_schema()` — widget schema per config field
- `PlayerRepository.get_by_slot()` — lookup player by slot_id
- `ThreadRegistry.get_rcon_client()` — expose live RCon client for kick/ban
- `RPTParser.list_log_files()` / `get_log_file_path()` — historical log access

## Test Commands

```bash
# Frontend unit tests
cd frontend && npx vitest run

# Frontend type check
cd frontend && npx tsc --noEmit

# Backend (no test suite yet)
```

## Key Implementation Notes

- `BanRepository.create()` takes `expires_at` (ISO string), not `duration_minutes` — convert in service
- `slot_id` is stored as a string in the `players` table — cast with `str(slot_id)` in queries
- Config field names in `ServerConfig` Pydantic model: `password_admin` (not `admin_password`), `battleye` (not `battle_eye`), `disable_von` (not `von`)
- Log directory defaults to `ARMA3_LOG_DIR` env var, falls back to `{server_dir}/logs`
