# focas-mock — vendored snapshot

Source: `C:\Users\dohertj2\Desktop\focas` (sibling project in this dev environment).

**Snapshot date:** 2026-04-24 (second refresh — pulled the native FOCAS2 Ethernet responder work in).

## Why vendored

OtOpcUa's FOCAS integration fixture runs against the Python mock server.
The upstream lives in its own repo; this directory is a verbatim
snapshot so CI can build the Docker image without network access to the
source repo and so OtOpcUa's test matrix pins a known-good revision.

The managed `WireFocasClient` speaks the mock's native FOCAS2 Ethernet
binary protocol directly — there's no longer a companion shim DLL.

## What's here

| Path | Purpose |
|------|---------|
| `src/focas_mock/` | Python package — TCP JSON/line-delimited mock server with 6 Fanuc CNC profiles |
| `pyproject.toml` | Package metadata; installs `focas-mock` CLI |
| `Dockerfile` | `python:3.11-slim` image built by the parent `docker-compose.yml` |
| `README.md` | Upstream README |
| `LICENSE` | MIT — permissive, vendoring allowed |


## Refreshing the snapshot

When upstream ships changes worth pulling:

```powershell
$src  = "C:\Users\dohertj2\Desktop\focas"
$dest = "$PWD"
Remove-Item -Recurse -Force "$dest\src" 2>$null
Copy-Item -Recurse "$src\src" "$dest\src"
Copy-Item "$src\pyproject.toml" "$dest\"
Copy-Item "$src\README.md" "$dest\"
Copy-Item "$src\LICENSE" "$dest\"
Copy-Item "$src\Dockerfile" "$dest\"
```

Update the snapshot date at the top of this file afterward. No other
files belong here — the Docker build context is just the Python package
and its metadata.
