This machine **is** the MicMap UAT rig (Bigscreen Beyond + Win11 Pro). SteamVR is installed and the user can start/stop it for phase verification or UAT runs — no separate test station.

**Installed driver location** (where SteamVR loads from at runtime):
- Driver root: `C:\Program Files (x86)\Steam\steamapps\common\SteamVR\drivers\micmap`
- DLL: `…\micmap\bin\win64\driver_micmap.dll`
- Sidecar: `…\micmap\bin\micmap.exe`
- vrsettings: `…\micmap\resources\settings\default.vrsettings`
- Pre-existing rotation backups: `driver_micmap.dll.{p5,v1.5}.bak`, `default.vrsettings.p5.bak`

**Build → install copy paths**:
- `build/driver/micmap/bin/win64/driver_micmap.dll` → `…/micmap/bin/win64/driver_micmap.dll`
- `build/bin/Debug/micmap.exe` → `…/micmap/bin/micmap.exe`

**Runtime HTTP port**: `27015` on `127.0.0.1` (per source `driver/resources/settings/default.vrsettings`). Older planning docs may reference `27115` — draft value, never shipped.

**User config dir**: `%APPDATA%\MicMap\` — `training_data.bin` lives here.

**Why**: Verified 2026-05-09 during P9 UAT prep. `vrpathreg show` lists `bigscreenbeyond` + `BeyondEyetracking` + `BeyondProximity` confirming Beyond rig identity.

**How to apply**: When UAT or HMD validation needed, do not ask the user to defer to a separate rig — this machine has the hardware. Use the install paths verbatim for build→install copy steps; back up installed files to `<name>.preuat.bak` before destructive UAT; restore from canonical source post-UAT.
