 Il worker gira in un container separato (`Dockerfile.vision`), non pubblica porte verso l'esterno ed è raggiungibile solo dal server all'indirizzo interno `http://vision:8100`. Il container non ha accesso al repository Git del progetto principale, quindi il commit di VisionSuite in uso (`engine_version`) non può essere scoperto dentro l'immagine: va stampato al momento del build leggendo il commit dalla macchina che esegue `docker compose build`, con la variabile `VISION_ENGINE_VERSION`. Una build senza questa variabile fallisce subito, invece di produrre un worker che risponde con una versione indovinata:

+## Camera di stazione (demo fiera, #72)
+
+Per acquisire il fotogramma da una camera locale (per esempio quella del TC bench) senza passare dall'upload, sul PC della stazione gira un piccolo servizio nativo, fuori da Docker, perché la camera GigE non si raggiunge dal container. Si avvia dalla radice del repository con l'ambiente di VisionSuite (`uv sync --all-packages` in `vendor/visionsuite`):
+
+```bash
+vendor/visionsuite/.venv/bin/python scripts/camera_service.py [--host 127.0.0.1] [--port 8765] [--folder <cartella immagini>]
+```
+
+Con `--folder` la sorgente `camera:folder` restituisce a rotazione le immagini della cartella, utile per provare senza hardware. Su Linux, perché il container `client` lo raggiunga, si usa `--host 172.17.0.1` (gateway di docker0; il compose di sviluppo mappa `host.docker.internal` su quell'host). Su Windows con Docker Desktop si presume che `host.docker.internal` raggiunga il loopback dell'host, ma va verificato sul PC della demo.
+
+⚠️ Il servizio non ha autenticazione: un `--host` diverso dal loopback va usato solo su una rete isolata.
+
+Nella schermata Stazioni si compilano `camera_url` (per esempio `http://host.docker.internal:8765`) e `camera_source` (`camera:<seriale>` oppure `camera:folder`). Per avere due postazioni sullo stesso PC si abilita `STATION_SWITCH_ENABLED`.

+"""Servizio camera minimo di stazione (TieMeasureFlow, #72).
+
+Cosa fa: espone via HTTP l'acquisizione di una camera (vs-camera: GigE/GenTL,

+`grab` (copiato da TieVision-Studio, src/visionsuite/gui/server.py):

+Errori: 400 parametri, 404 sorgente inesistente, 503 guasto camera, 504 timeout.
+Serve perche' vs-gui ascolta solo su 127.0.0.1 e il container `client` non lo
+raggiunge; questo servizio permette di scegliere l'host di ascolto.
