Part of #734. The physical and network work that makes a Linux body usable in a venue rather than on a desk.
- msi1060 is currently in PRODUCTION district bxl1, venue ad6. Move it to bxl1-test* for this work, per the test-districts rule, and only return it to a production district when the rest of #734 is done.
- Wire its ethernet. enp61s0 is DOWN; it runs on WiFi wlp62s0 at a 270 Mbit/s link, and a 200+ Mbit/s stream cannot share that band with the headset. A wired server is not optional for PyroWave.
- Dedicated 6 GHz AP for the headset, per the hardware requirements in the fork runbook.
- Confirm the headset reaches the body on the venue LAN and not over the WireGuard mesh. Mesh routing measured 50-165 ms RTT versus about 5 ms on the LAN, which is fatal on its own.
- Document the Linux body build in hydravenues alongside the existing venue hardware.
