Where each check runs first

Linux leads, and Windows is the peer it is checked against (ADR-0241, NFR §9). A live check — capture, a second display, a projector, a rehearsal — runs on the Arch reference box first. The Windows box takes it second, for the peer platform. A check that names a Windows-only surface runs only there, and one gated on the iGPU floor box waits for that box. The Linux column says what is expected, not what has been run. Each section’s own record says that.

Check	Linux (Arch, the reference)	Windows (the peer)
The stereo field, by ear	First	Second
Frame cost and look, on the low-end box	Not the floor box	The older iGPU PC
The overlay’s frame-time p99; the dither on a second display	First	Second
A live input unplugged and re-plugged; a 96 kHz interface	No device picker	Only here
The live video-out’s size ceiling (Spout)	No Spout	Only here
The operator console on two displays	First; Plan 0218 Phase 1 had one display, so the two-display half is owed	Second
The Rich tier calibration	First, on the dGPU	Second
The foobar2000 component’s install	No foobar2000	Only here
The studio beside the player	First	Ran 2026-09-11
The OSC bindings at the rig	First	Second
The Linux standalone on a real desktop	Arch, and the Ubuntu box	—
The adapter switch on a two-adapter box	First; the Arch box has two	Second, on a hybrid box
The Floor reading NFR §1 asserts	Not the floor box	The older iGPU PC
