```bash
# Arrancar (default: 127.0.0.1:8484)
cd apps/sqlite_api && go run -tags fts5 .

# Bind personalizado
go run -tags fts5 . --bind 0.0.0.0:8484
```

## Endpoints

| Metodo | Path | Descripcion |
|--------|------|-------------|
| GET | `/health` | Health check |
| GET | `/api/databases` | Lista DBs disponibles (registry + ops:*) |
| GET | `/api/databases/:db/tables` | Tablas y vistas de una DB |
| GET | `/api/databases/:db/schema` | Schema SQL completo |
| POST | `/api/databases/:db/query` | Ejecuta query SQL read-only |
| GET | `/api/databases/:db/fts?q=...&table=...` | Busqueda FTS5 directa |

## Seguridad

- Solo queries SELECT, PRAGMA, WITH y EXPLAIN
- SQLite abierto con `?mode=ro` (read-only a nivel driver)
- Timeout de 5 segundos por query
- Bind a localhost por defecto
- CORS habilitado para acceso desde frontends

## Bases de datos

- `registry` — registry.db de la raiz
- `ops:{app}` — operations.db de apps/{app}/ y projects/*/apps/{app}/

Auto-descubre operations.db al arrancar escaneando apps/ y projects/*/apps/.

## Health check

```bash
curl http://localhost:8484/health
# {"status":"ok"}
```

## Puerto

8484 (no colisiona con Metabase 3000, Jupyter 8888, deploy_server 9090).
