# Patch Panel Runtime Fixture

`two-box-sync.json` is a local runtime smoke fixture for `hwlab-patch-panel`.
It starts two `hwlab-box-simu` services and applies one active wiring config to
the patch panel.

The smoke proves that patch-panel-owned propagation can synchronize:

```text
res_boxsimu_runtime_1:DO1 -> res_boxsimu_runtime_2:DI1
res_boxsimu_runtime_1:AO1 -> res_boxsimu_runtime_2:AI1
res_boxsimu_runtime_1:FREQ_OUT1 -> res_boxsimu_runtime_2:FREQ_IN1
```

The local smoke does not deploy DEV/PROD services, connect to real hardware, or
write audit rows.
