+# Cosa fa: submodule vendor/visionsuite (deploy key), build.ps1 (uv sync Python 3.13, Tailwind,
+# Nuitka --standalone, migrazioni .pyc, DLL di WeasyPrint, Inno Setup), poi il setup come
+# artifact e come asset della release Gitea del tag.
+# Da cosa dipende: un runner Gitea con label `windows` che giri su un host Windows (non in
+# container) con Visual Studio/Build Tools (MSVC), git e node (serve a actions/checkout e a
+# Tailwind); uv e Inno Setup li installa il workflow se mancano. Secret SUBMODULI_SSH_KEY
+# (deploy key di sola lettura di TieVision-Core, impostato sul repo il 17/10/2026).
+# Il runner `windows` e' act_runner in modalita' host su daitarn (capacity 1).
+# ⚠️ upload-artifact@v3: e' la versione che usa gia' vs-native.yml in TieVision-Core su questo
+# Gitea; la v4 usa un protocollo che act_runner puo' non supportare.
+# ⚠️ L'asset della release usa il token del job (secrets.GITHUB_TOKEN): se la chiamata risponde
+# 403 serve un token personale in un secret (es. RILASCI_TOKEN) al posto di GITHUB_TOKEN.
+# ⚠️ La build da freddo e' lunga (Nuitka compila backend, visione, plotly, opencv...): timeout 180 min.

+Il runner di visione (`src/vision/`) e il suo worker FastAPI (`src/vision_worker/`) dipendono da `vendor/visionsuite`, un **submodule** che punta al repo TieVision-Core (`ssh://git@git.tielogic.xyz:222/Adriano/TieVision-Core.git`, ex visionsuite, rinominato il 15/10/2026; `vs-gui` e `vs-assistant` sono ora in TieVision-Studio e TieVision-Assistant, che TieMeasureFlow non usa; il path resta `vendor/visionsuite`): un `git clone` senza `--recurse-submodules` lascia la cartella vuota (chi ha già clonato: `git submodule update --init`). Le librerie di VisionSuite richiedono **Python 3.13**, mentre backend e frontend restano su Python 3.11 — è un albero a parte nel monorepo, isolato con il proprio extra `uv`.
+
+Regola (Adriano, 07/10/2026): il submodule `vendor/visionsuite` segue `origin/main`: a ogni integrazione si porta all'ultimo commit (`git -C vendor/visionsuite fetch origin && git -C vendor/visionsuite checkout origin/main`) e si rilanciano i test della visione. La regola vale ora per `origin/main` di TieVision-Core. Pin attuale: 2e73691.
 
 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:

+
+- File: `packaging/windows/avvio.py` (entry point: licenza, `config.env`, variabili d'ambiente, migrazioni, quattro server in thread), `build.ps1` (uv sync 3.13, Tailwind, Nuitka `--standalone`, migrazioni come `.pyc`, Inno Setup), `TieMeasureFlow.iss`, `TieMeasureFlow.ico`; CI `.gitea/workflows/rilascio-windows.yml` (tag `v*`, runner con etichetta `windows`); test in `packaging/windows/tests/` (licenza firmata con la chiave di prova del contratto, server e migrazioni sostituiti). Piani collegati: SQLite su file (#77) e PDF/DLL (#78). Modello: TieVision-Studio#1.
+- Un solo processo `TieMeasureFlow.exe`: thread `web` (Flask + waitress, `--host`, 8780), `backend` (8000), `vision` (8100), `camera` (8765) con uvicorn. Dati in `%PROGRAMDATA%\Tielogic\TieMeasureFlow` (`tmf.db`, `uploads`, `camera`, `log`, `config.env`); licenza in `%PROGRAMDATA%\Tielogic\licenze\tiemeasureflow.json` (mai nel repo).
+- ⚠️ Python del pacchetto: 3.13 in un ambiente separato (`build\venv313`, `UV_PROJECT_ENVIRONMENT`); il repo resta su `.python-version` 3.11 per lo sviluppo. `vs-license` e `vs-camera` hanno il marker `python_version>='3.13'` nel gruppo `windows`, altrimenti `uv lock` fallisce sul `requires-python >=3.11`.
+- ⚠️ Le variabili d'ambiente si impostano PRIMA di importare backend e frontend (leggono la configurazione all'import): in `avvio.py` gli import pesanti stanno dentro le funzioni. `APP_ENV=production` rifiuta i segreti di default, quindi `config.env` genera anche `DB_PASSWORD` (inutilizzata con SQLite).
+- ⚠️ Il frontend Flask non è un pacchetto (`from config import Config`, `blueprints`, `services`, `app`) e `scripts/camera_service.py` neppure: da sorgente `avvio.py` aggiunge `flask_app` e `scripts` al `sys.path`; per Nuitka `build.ps1` li mette su `PYTHONPATH` e li include con `--include-module/--include-package`. I dati di Flask (`templates`, `static`, `translations`) vanno nella radice della cartella standalone, `src\backend\templates` sotto `src\backend`.
+- ⚠️ Il browser parla con Flask (8780); la pagina di setup `/api/setup` invece è del backend: si apre su `http://127.0.0.1:8000/api/setup` (in Docker la serve nginx). `avvio.py` la apre da sola se il database non ha utenti.
+- ⚠️ Alembic carica `env.py` e `versions\` dal disco, quindi Nuitka non può compilarli: `build.ps1` li copia come soli `.pyc` (`compileall -b`) e `avvio.py` esegue `upgrade head` con `sourceless=true`. È l'unica eccezione al «nessun `.py`/`.pyc`»: il controllo finale di `build.ps1` ammette `.pyc` solo sotto `src\backend\migrations`. `env.py` chiama `fileConfig`, che azzera i gestori del log: `avvio.py` li ricrea dopo le migrazioni.
+- ⚠️ `numba` è escluso dal pacchetto (`--nofollow-import-to=numba`): le funzioni compilate da Nuitka non hanno bytecode e numba non può farne il JIT. Core e pm2d hanno il ripiego in Python puro (`HAS_NUMBA=False`): funziona ma il matching è più lento. Da misurare sul TC bench.
+- ⚠️ L'exe è senza console: `sys.stdout`/`sys.stderr` possono essere `None` (`avvio.py` li sostituisce con il device nullo), uvicorn gira con `log_config=None` e il log va su file (`...\log\tiemeasureflow.log`). I server uvicorn girano in thread (nessun signal handler) e waitress si crea con `create_server`.
+- ⚠️ `visionsuite` è un namespace condiviso da più distribuzioni: `build.ps1` elenca i sottopacchetti dagli `__path__` e i metadati con `--include-distribution-metadata`. Un nuovo pacchetto di Core si prende da solo se è in `[tool.uv.sources]` e nel gruppo.
+- ⚠️ `tailwind.css` non è nel repo: `build.ps1` lo genera con `npx tailwindcss@3.4.19` (stessa versione di `Dockerfile.frontend`); serve Internet solo a chi costruisce. Il setup finale non ha bisogno di Internet.
+- ⚠️ Chrome o Edge servono a kaleido per i grafici dei report: `avvio.py` imposta `BROWSER_PATH` al primo trovato. Le DLL di WeasyPrint le scarica `packaging/windows/pdf/prendi-gtk.ps1` (piano #78) in `gtk\` accanto all'exe.
+- ⚠️ `SETUP_PASSWORD` e le chiavi stanno in `config.env`, in una cartella scrivibile da tutti gli utenti locali (serve all'exe, che gira con l'utente che lo lancia): non è un luogo per segreti ad alto valore.
+- ⚠️ CI di rilascio: il runner `windows` è su daitarn (act_runner, modalità host, capacity 1); `upload-artifact` è alla v3. Non committare `build/` e `dist/`.
+- ⚠️ `STATION_CODE`: senza una stazione l'interfaccia risponde 503 («Stazione non configurata»). `config.env` nasce con `STATION_CODE=ST-DEFAULT` (la stazione creata dal seed della pagina di setup); le chiavi extra di `config.env` (`STATION_CODE`, `STATION_SWITCH_ENABLED`, ...) passano all'ambiente ma non sovrascrivono le variabili fisse del contratto.
+- ⚠️ Alembic anche fuori da `avvio.py`: `setup.py` (`_stamp_head`) apre `alembic.ini` con un `Config` suo, quindi `build.ps1` scrive `sourceless = true` nell'`alembic.ini` del pacchetto; e `env.py` chiama `logging.config.fileConfig`, che azzererebbe il log su file, quindi `avvio.py` lo sostituisce con un no-op.
+- ⚠️ Bug noto, non del pacchetto: `POST /api/setup/init-db` risponde 500 (`asyncio.run() cannot be called from a running event loop`, perché `_stamp_head` esegue `env.py` dentro il loop). Nel pacchetto non serve: le migrazioni creano già le tabelle; la pagina di setup si usa per «Seed» o per creare l'amministratore.
+- ⚠️ Le richieste di login all'API sono limitate (5 al minuto): negli script di prova distanziarle.

+## 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`.
+
+---
+
+## Pacchetto Windows
+
+Per i PC senza Docker (per esempio il PC della stazione in fiera) TieMeasureFlow si distribuisce come programma di installazione per Windows, `TieMeasureFlow-setup-<versione>.exe`. Funziona completamente offline, non richiede Docker né MySQL, e non contiene codice sorgente Python: il codice del prodotto è compilato con Nuitka. Il programma parte solo con una licenza valida, legata al computer.
+
+### Installazione
+
+1. Eseguire `TieMeasureFlow-setup-<versione>.exe` (serve un account amministratore; per una prova senza amministratore si può lanciare il setup con `/CURRENTUSER`). Per un'installazione silenziosa: `/VERYSILENT /SUPPRESSMSGBOXES /NORESTART`.
+2. Dal menu Start aprire «Impronta di questo computer» e comunicare l'impronta a Tielogic. L'impronta viene salvata anche in `C:\ProgramData\Tielogic\licenze\impronta-tiemeasureflow.txt`.
+3. Copiare il file di licenza ricevuto in `C:\ProgramData\Tielogic\licenze\tiemeasureflow.json`. La licenza non è inclusa nel setup e non va mai inserita nel repository.
+4. Avviare «TieMeasureFlow» dal menu Start o dal desktop. Senza una licenza valida (mancante, scaduta, di un altro computer o di un altro prodotto) il programma mostra il motivo e l'impronta ed esce.
+
+### Primo avvio
+
+Il programma gira in un solo processo, senza finestra, e apre il browser. Ascolta solo sul computer locale (`127.0.0.1`); per raggiungere l'interfaccia da altri dispositivi della rete si avvia l'exe con `--host 0.0.0.0` (per esempio da un collegamento personalizzato).
+
+| Componente | Indirizzo |
+|---|---|
+| Interfaccia web (Flask) | http://127.0.0.1:8780/ |
+| Backend API (FastAPI) | http://127.0.0.1:8000/ |
+| Worker di visione | http://127.0.0.1:8100/ |
+| Camera della stazione | http://127.0.0.1:8765/ (`/camera/sources`) |
+
+Al primo avvio vengono create la cartella dati `C:\ProgramData\Tielogic\TieMeasureFlow` e il file `config.env` con le chiavi segrete generate (`SERVER_SECRET_KEY`, `CLIENT_SECRET_KEY`, `SETUP_PASSWORD`, `DB_PASSWORD`); al riavvio vengono rilette, quindi le sessioni e le password restano valide. Il database è un file SQLite (`tmf.db`); le migrazioni si applicano da sole a ogni avvio.
+
+Se il database non contiene ancora utenti, il browser si apre direttamente sulla pagina di setup `http://127.0.0.1:8000/api/setup`. La pagina chiede la `SETUP_PASSWORD`, che si legge in `config.env`, e permette di inizializzare il database e creare il primo amministratore (vedi «Setup Iniziale»). Terminato il setup si accede all'interfaccia su `http://127.0.0.1:8780/`.
+
+Per le camere della stazione si compila nella schermata Stazioni `camera_url` = `http://127.0.0.1:8765` e `camera_source` (`camera:<seriale>` oppure `camera:folder`). Con `camera:folder` il servizio restituisce a rotazione le immagini che si copiano in `C:\ProgramData\Tielogic\TieMeasureFlow\camera`. Per le camere GigE/GenTL il driver (producer `.cti`) è quello installato dal produttore della camera.
+
+Altre informazioni utili:
+
+- I log sono in `C:\ProgramData\Tielogic\TieMeasureFlow\log\tiemeasureflow.log`.
+- Una seconda esecuzione mentre il programma è già attivo apre soltanto il browser.
+- Per fermare il programma si usa «Arresta TieMeasureFlow» nel menu Start (chiude il processo).
+- La disinstallazione non cancella licenze, database, file caricati e `config.env`: sono dati del cliente.
+- I report PDF usano le librerie grafiche incluse nel pacchetto e un browser Chrome o Edge già installato sul computer per i grafici.
+
+### Come si costruisce
+
+Il setup lo produce la CI Gitea (`.gitea/workflows/rilascio-windows.yml`) quando si crea un tag `v*`, su un runner con etichetta `windows`; il file compare come allegato della release. In locale, dalla radice del repository con il sottomodulo `vendor/visionsuite` inizializzato:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File packaging\windows\build.ps1 -Versione 3.0.0
+```
+
+Servono `uv`, Node.js, Visual Studio con il carico C++ e Inno Setup 6. Il risultato è `dist\TieMeasureFlow-setup-3.0.0.exe`. La prima compilazione richiede decine di minuti. I test dell'avvio si lanciano con l'ambiente Python 3.13 del pacchetto: `uv run --python 3.13 --extra server --extra client --extra vision-worker --group windows --with pytest pytest packaging/windows/tests -q`.

+; crea in ProgramData le cartelle scrivibili da tutti gli utenti (licenze, uploads, camera, log)
+; e i collegamenti in menu Start e sul desktop.

+;   ISCC /DVersione=3.0.0 /DVersione4=3.0.0.0 /DOrigine=build\nuitka\avvio.dist /DUscita=dist TieMeasureFlow.iss
+; Setup silenzioso: TieMeasureFlow-setup-X.exe /VERYSILENT /SUPPRESSMSGBOXES /NORESTART

+; ATTENZIONE: la licenza NON e' nel setup: va copiata in {commonappdata}\Tielogic\licenze\tiemeasureflow.json
+; (la cartella e' scrivibile dagli utenti). La disinstallazione lascia licenze, database (tmf.db),

+"""Entry point del pacchetto Windows di TieMeasureFlow (TieMeasureFlow#76).
+
+Cosa fa: controlla la licenza (prodotto "tiemeasureflow"); se non e' valida mostra il
+motivo e l'impronta del computer, scrive l'impronta in
+%PROGRAMDATA%\\Tielogic\\licenze\\impronta-tiemeasureflow.txt ed esce con 1.
+Se e' valida: prepara la cartella dati (%PROGRAMDATA%\\Tielogic\\TieMeasureFlow, con
+config.env dei segreti generati al primo avvio), imposta le variabili d'ambiente del
+contratto, esegue le migrazioni Alembic (SQLite su file) e avvia in un solo processo
+quattro server, ciascuno nel suo thread:
+  web      Flask (src/frontend/flask_app) servito da waitress, --host (default 127.0.0.1) :8780
+  backend  FastAPI src.backend.main:app, 127.0.0.1:8000
+  vision   FastAPI src.vision_worker.main:app, 127.0.0.1:8100
+  camera   scripts/camera_service.py (camere della stazione), 127.0.0.1:8765
+Poi apre il browser. Se un'altra copia e' gia' in esecuzione apre solo il browser.
+
+Come si usa: e' l'exe compilato con Nuitka (build.ps1); da sorgente, dalla radice del repo
+con l'ambiente 3.13 del pacchetto: `python packaging/windows/avvio.py [--impronta] [--host H]`.
+Opzioni di servizio: `--senza-finestre` (niente MessageBox, solo stderr: serve alle prove
+automatiche; NON salta il controllo di licenza) e `--senza-browser`.
+
+Dipende da: visionsuite.license (vs-license, contratto licenza v1), uvicorn, waitress, alembic.
+
+⚠️ L'exe e' senza console: stdout/stderr possono essere None, quindi il log va su file
+(<dati>\\log\\tiemeasureflow.log) e uvicorn gira con log_config=None.
+⚠️ Le variabili d'ambiente vanno impostate PRIMA di importare backend e frontend (leggono
+la configurazione all'import): per questo gli import pesanti stanno dentro le funzioni.
+⚠️ La cartella ProgramData la rende scrivibile agli utenti l'installer (.iss).

+<#
+Pacchetto Windows di TieMeasureFlow (TieMeasureFlow#76).
+
+Cosa fa: uv sync in un ambiente Python 3.13 separato (build\venv313), frontend (Tailwind +
+traduzioni), compila avvio.py con Nuitka in modalita' --standalone (cartella, NON onefile:
+l'onefile si decomprime in %TEMP% ad ogni avvio), aggiunge le migrazioni Alembic come soli
+.pyc, le DLL di WeasyPrint (piano B) e il commit del motore di visione, poi Inno Setup
+produce dist\TieMeasureFlow-setup-<versione>.exe. Sul PC del cliente non finisce nessun
+.py; i .pyc ci sono solo in src\backend\migrations (Alembic le carica dal disco).
+
+Come si usa (dalla radice del repo, con il submodule vendor/visionsuite inizializzato):
+  powershell -ExecutionPolicy Bypass -File packaging\windows\build.ps1 [-Versione 3.0.0]
+-Versione accetta anche un tag (v3.0.0, v3.0.0-rc1): si usano i numeri iniziali.
+Senza -Versione si usa la variabile GITHUB_REF_NAME (tag nella CI) o 0.0.0.
+-SenzaSetup si ferma dopo Nuitka (cartella build\nuitka\avvio.dist).
+
+Dipende da: uv, node/npx (Tailwind 3.4.19 da npm: serve Internet SOLO a chi costruisce),
+Visual Studio con carico C++ (MSVC; Nuitka lo trova da solo), Inno Setup 6
+(`winget install --id JRSoftware.InnoSetup -e`; ISCC.exe nel PATH, in Program Files o in
+%LOCALAPPDATA%\Programs). Nuitka e' nel gruppo uv "windows" (pyproject.toml).
+
+⚠️ La prima compilazione e' lunga (decine di minuti: numpy/opencv/scipy/plotly); le successive
+riusano la cache di Nuitka (%LOCALAPPDATA%\Nuitka) e la cartella build\nuitka.
+⚠️ I pacchetti di Core condividono il namespace visionsuite (extend_path): Nuitka non lo
+segue da solo, quindi i sottopacchetti si elencano uno per uno dagli __path__ installati.
+⚠️ numba e' escluso di proposito: le funzioni compilate da Nuitka non hanno bytecode e numba
+non puo' farne il JIT. Core e pm2d hanno gia' il ripiego in Python puro (HAS_NUMBA=False):
+funziona ma e' piu' lento nel matching.
+⚠️ Il frontend Flask non e' un pacchetto (`from config import Config`, `blueprints`, `services`):
+si compila mettendo flask_app e scripts su PYTHONPATH, come fa avvio.py in sviluppo.

+# Report PDF nel pacchetto Windows
+
+Questa cartella contiene quello che serve perché i report PDF di TieMeasureFlow
+(`src/backend/services/report_service.py`: Jinja2, Plotly con Kaleido 1.2.0, WeasyPrint 68.1)
+funzionino su Windows, dentro il pacchetto, **senza Internet**. Riferimento: TieMeasureFlow#78
+(parte del pacchetto Windows, madre #76).
+
+## Come funziona
+
+Un report SPC passa da due componenti nativi che su Windows non arrivano con `pip`:
+
+1. **WeasyPrint** disegna il PDF e carica a runtime le DLL di Pango/GTK
+   (`libgobject-2.0-0`, `libpango-1.0-0`, `libharfbuzz-0`, `libharfbuzz-subset-0`,
+   `libfontconfig-1`, `libpangoft2-1.0-0` e le loro dipendenze).
+2. **Kaleido 1.x** trasforma i grafici Plotly in SVG pilotando un browser Chromium già installato
+   (non porta più Chromium con sé). Su ogni Windows 10/11 c'è Edge.
+
+### Le DLL: `prendi-gtk.ps1`
+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File packaging\windows\pdf\prendi-gtk.ps1 -Destinazione <cartella>
+```
+
+- Scarica da `repo.msys2.org` (ucrt64) 21 pacchetti **pinnati con sha256** (nome file e hash stanno nello
+  script), verifica l'hash, estrae solo le 27 DLL necessarie, `etc\fonts` di fontconfig e le licenze.
+- Idempotente: se la cartella è già pronta (file `.gtk-pin` uguale ai pin dello script) esce subito.
+- Se un hash non coincide fallisce e non lascia mezza cartella.
+- I pacchetti scaricati stanno in `%LOCALAPPDATA%\Tielogic\tmf-gtk-cache` (`-Cache` per cambiarla).
+- Serve Internet **solo alla build**. Estrae `.zst` con `tar.exe` di Windows (verificato: bsdtar 3.8.9 con
+  zstd); se `tar.exe` non sa di zstd ripiega su `uv run --with zstandard`.
+- Gira da utente non admin con PowerShell 5.1.
+- ⚠️ `repo.msys2.org` tiene solo le versioni recenti: se un file pinnato sparisce (404) vanno aggiornati nome
+  e sha256 dal db `https://repo.msys2.org/mingw/ucrt64/ucrt64.db` e rifatto il test. Conservare la cache
+  (Wasabi o NAS) evita la corsa contro il repository.
+
+Il piano C copia `<cartella>` in `P\gtk\` (P = cartella programma).
+
+### Variabili d'ambiente (le imposta `avvio.py`, piano C)
+
+| Variabile | Valore | Perché |
+|---|---|---|
+| `WEASYPRINT_DLL_DIRECTORIES` | `<P>\gtk` | WeasyPrint chiama `os.add_dll_directory` su ogni cartella (separatore `;`) **prima** di caricare le DLL. Va impostata prima di importare `weasyprint` (lo fa `report_service` all'import). |
+| `BROWSER_PATH` | `msedge.exe` o `chrome.exe` | Choreographer (sotto Kaleido) la legge da sé e ha la precedenza su ogni ricerca (verificato: un percorso inesistente dà `FileNotFoundError`). Senza la variabile Kaleido cerca Edge/Chrome da solo (registro e percorsi tipici). Nessun codice in `report_service.py` per questo. |
+
+Fontconfig non richiede variabili: trova `etc\fonts` accanto alle DLL (verificato). Se manca `etc\fonts`
+WeasyPrint stampa "Fontconfig error: Cannot load default config file". I font dei report vengono da
+`C:\Windows\Fonts`.
+
+### MathJax: la modifica a `report_service.py`
+
+Kaleido 1.x inserisce nella pagina di render uno `<script>` MathJax da `cdnjs.cloudflare.com` anche quando i
+grafici non hanno formule. Misurato su daitarn con Edge: con rete che scarta i pacchetti ogni grafico aspetta
+~19 s (due grafici per report SPC); con rete che rifiuta subito ~2 s. `report_service.py` imposta
+`pio.defaults.mathjax` su un file `.js` vuoto in `%TEMP%` (`tmf-mathjax-vuoto.js`): nessuna richiesta di rete,
+report SPC in ~7 s anche a rete bloccata. Se un giorno i grafici useranno LaTeX, qui serve un MathJax locale.
+`plotly.min.js` invece è già locale (dentro il pacchetto `plotly`).
+
+## Flag Nuitka e dati da includere (per `build.ps1`, piano C)
+
+⚠️ Stato: ricavati leggendo i sorgenti installati (versioni del `uv.lock`); **non provati con una build
+Nuitka**: la verifica è la prima build di C. I dati e i metadati sono quelli che il codice legge davvero da disco.

+Dati dei pacchetti (file non `.py` letti a runtime):
+
+```text
+--include-package-data=weasyprint     # css/html5_ua.css, html5_ph.css, html5_ua_form.css, pdf/sRGB2014.icc
+--include-package-data=pyphen         # dictionaries/*.dic (84 file, sillabazione)
+--include-package-data=kaleido        # vendor/kaleido_scopes.js (pagina di render)
+--include-package-data=plotly         # package_data/plotly.min.js (Kaleido lo cerca come file accanto a plotly/__init__), templates/*.json, validators/_validators.json
+--include-package-data=tzdata         # zoneinfo: Windows non ha il database IANA (vedi sotto)
+--include-data-dir=src/backend/templates=src/backend/templates   # Jinja2: report_service legge i .html dal disco
+```
+
+`choreographer/resources/last_known_good_chrome.json` serve solo al comando che scarica Chrome: non serve.
+
+Metadati delle distribuzioni (`importlib.metadata.version` al momento dell'import): senza, `import plotly` e
+Kaleido falliscono con `PackageNotFoundError`:
+
+```text
+--include-distribution-metadata=plotly
+--include-distribution-metadata=kaleido
+```
+
+Import dinamici che l'analisi statica di Nuitka può perdere:
+
+```text
+--include-package=fontTools            # ttLib/ttFont.py importa le tabelle con __import__("fontTools.ttLib.tables." + tag)
+--include-package=plotly               # _plotly_utils/importers.py: importlib.import_module lazy dei moduli graph_objs
+--include-package=_plotly_utils
+--include-module=_cffi_backend         # WeasyPrint usa cffi in modalita' ABI (dlopen), serve il modulo C di cffi
+--include-package=weasyprint
+--include-package=kaleido
+--include-package=choreographer
+```
+
+Altre note per C:
+
+- WeasyPrint salta `os.add_dll_directory` se `sys.frozen` esiste (`weasyprint/text/ffi.py`). Nuitka di norma
+  non lo imposta (PyInstaller sì): se in `TieMeasureFlow.exe` le DLL non si trovassero, chiamare
+  `os.add_dll_directory(<P>\gtk)` da `avvio.py` prima dell'import.
+- Le DLL **non** vanno compilate né incluse da Nuitka: restano file in `P\gtk\`.
+- Il controllo "nessun `.py`" di `build.ps1` non deve scandire `gtk\` (non ci sono `.py`, ma è meglio
+  saperlo) né `licenze\`.
+- **`tzdata` manca da `pyproject.toml`**: su Windows `ZoneInfo("Europe/Rome")` (usato da
+  `src/backend/utils/tempo.py`, quindi da ogni report) dà `ZoneInfoNotFoundError`. Va aggiunto
+  `tzdata; sys_platform == 'win32'` agli extra server e client (o al gruppo `windows`) e il frontend
+  (`src/frontend/flask_app/app.py` usa `ZoneInfo`) ne ha bisogno allo stesso modo.
+- `pdfplumber` è già nell'extra `server` (il test lo usa per leggere i PDF).
+
+## Licenze delle DLL
+
+Le DLL sono binari MSYS2/MinGW (ucrt64) non modificati, collegati dinamicamente. `prendi-gtk.ps1` mette in
+`<cartella>\licenze\` i testi di licenza di ogni pacchetto più un `<pacchetto>.txt` con nome del file e licenza.
+**L'installer deve includere `gtk\licenze\`.**
+
+| Libreria | Licenza |
+|---|---|
+| Pango, GLib/GObject/GIO, fribidi, libthai, libdatrie, graphite2, libintl (gettext-runtime), libiconv | LGPL 2.1 o successive |
+| FreeType | FTL oppure GPL 2+ (si sceglie FTL) |
+| HarfBuzz, expat, libffi, brotli, fontconfig | MIT / permissiva |
+| libpng, zlib-ng, bzip2, pcre2 | permissive (libpng, Zlib, bzip2, BSD-3) |
+| libgcc, libstdc++ | GPL 3 con GCC Runtime Library Exception (ridistribuzione libera) |
+| libwinpthread | MIT e BSD-3 |
+
+Per le librerie LGPL, chi riceve il pacchetto può sostituire le DLL (sono file separati in `gtk\`); i sorgenti
+sono pubblici su MSYS2 (`https://packages.msys2.org/`), e l'elenco esatto delle versioni è nello script.
+
+## Test
+
+`src/backend/tests/test_report_windows.py` (saltato fuori da Windows, senza DLL, senza Edge/Chrome o senza
+`tzdata`): in un sottoprocesso con WeasyPrint **vero** (il `conftest.py` altrimenti lo sostituisce con un
+mock) genera su SQLite in memoria il report SPC (carta di controllo e istogramma) e quello a tabella, e
+controlla con `pdfplumber` byte `%PDF-`, almeno una pagina, titoli dei grafici e segni vettoriali.
+
+```powershell
+# DLL (una volta) e test
+powershell -NoProfile -ExecutionPolicy Bypass -File packaging\windows\pdf\prendi-gtk.ps1 -Destinazione packaging\windows\pdf\gtk
+uv run --python 3.13 --extra server --extra dev pytest src/backend/tests/test_report_windows.py -q
+```
+
+`packaging/windows/pdf/gtk/` e `cache/` sono in `.gitignore`: le DLL non si committano.
+
+### Prova a rete bloccata
+
+`HTTP_PROXY`/`HTTPS_PROXY` non bastano: Edge e Chrome usano il **proxy di sistema** di Windows. Per provare davvero
+il PC senza Internet: impostare temporaneamente il proxy di sistema (Impostazioni, Rete, Proxy) su un indirizzo
+morto (`127.0.0.1:9` rifiuta subito; `10.255.255.1:8080` scarta i pacchetti, il caso peggiore), generare i
+report e **ripristinare** il proxy. Esito del 2026-10-17 con proxy che scarta i pacchetti: report SPC e report a
+tabella completi in ~7 s.

+ prendi-gtk.ps1 - prepara le DLL di Pango/GTK che WeasyPrint 68.1 vuole su Windows.
+
+ COSA FA: scarica da repo.msys2.org (ucrt64) un elenco FISSO di pacchetti, ne verifica lo sha256,
+   estrae solo le DLL che servono a WeasyPrint (+ etc\fonts di fontconfig e le licenze) in -Destinazione.
+ COME SI USA: powershell -NoProfile -ExecutionPolicy Bypass -File prendi-gtk.ps1 -Destinazione <cartella>
+   Opzionali: -Cache <cartella> (pacchetti scaricati, default %LOCALAPPDATA%\Tielogic\tmf-gtk-cache),
+              -Forza (rifa' anche se la cartella e' gia' pronta).
+ DA COSA DIPENDE: Windows 10/11 con tar.exe (bsdtar con zstd) oppure uv + Python (modulo zstandard);
+   Internet solo al momento della build, mai a runtime. PowerShell 5.1 va bene, non serve admin.
+ IDEMPOTENTE: se la cartella ha gia' le DLL e il file .gtk-pin coincide con questi pin, esce senza scaricare.
+ FALLISCE se lo sha256 di un pacchetto non coincide (nessun file parziale resta in -Destinazione).
+ TRAPPOLA: repo.msys2.org tiene solo le versioni recenti. Se un file pinnato sparisce (404) serve aggiornare
+   i pin qui sotto (nome file + sha256 dal db https://repo.msys2.org/mingw/ucrt64/ucrt64.db) e riprovare i test.
+   La -Cache conserva i pacchetti gia' scaricati: copiarla su Wasabi/NAS evita il problema.

+"""Servizio camera minimo di stazione (TieMeasureFlow, #72).
+
+Cosa fa: espone via HTTP l'acquisizione di una camera (vs-camera: GigE/GenTL,
+OpenCV, cartella di immagini) con lo stesso contratto di `vs-gui`, ma solo
+`grab` (copiato da TieVision-Studio, src/visionsuite/gui/server.py):
+  GET  /camera/sources   -> {"sources": [{name, kind, label}]}
+  POST /camera/grab      json {source, trigger="continuo", timeout_ms=5000} -> PNG
+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.
+
+Uso (dalla radice del repo):
+  vendor/visionsuite/.venv/bin/python scripts/camera_service.py \
+      [--host 127.0.0.1] [--port 8765] [--folder <cartella immagini>]
+  --folder abilita la sorgente finta `camera:folder` (loop sulle immagini).
+  Da Docker su Linux: --host 172.17.0.1 (gateway di docker0).
+
+Dipende da: venv di VisionSuite (`uv sync --all-packages` in vendor/visionsuite):
+vs-camera, fastapi, uvicorn, opencv.
+
+AVVERTENZA: nessuna autenticazione. Un --host diverso dal loopback espone la
+camera a chiunque raggiunga la porta: solo su rete isolata.

+ *   trascinabile e ridimensionabile (mouse e touch, Pointer Events). Per un PDF
+ *   rasterizza la pagina scelta con pdf.js (>= 2000 px sul lato lungo).
+ *   Risolve: Blob PNG del ritaglio (a piena risoluzione) | il file originale
+ *   ("Usa originale") | null ("Annulla").
+ * Come si usa: ImageCrop.configure({pdfSrc, workerSrc, labels}) una volta dal
+ *   template (URL di vendor/pdf e stringhe tradotte), poi `await ImageCrop.open(file)`.
+ * Dipendenze: nessuna obbligatoria. pdf.js (gia' vendorizzato) viene caricato
+ *   al bisogno solo per i PDF; il ritaglio usa un canvas 2D semplice invece di
+ *   fabric.js perche' serve solo un rettangolo, non un editor di oggetti.
