ft-gazed runs ft-gaze, drops blinks and dropouts, smooths with a fixation lock, applies the probe's calibration plus what the pointer has taught since, and sends the corrected gaze to the pointer helper at 90 Hz. The helper sends lessons back (a nudge before a click), which are learned and saved. It only reads the eye tracker; nothing of SteamVR's is written. gaze/run.sh installs it as a user service that starts with SteamVR; ft-gazectl turns gaze mode on and off and shows the service's status.
