DeeJanuzandClaude Opus 5.5 e01defd36d pointer: three-finger scrolls start and keep going more reliably
User, 2026-10-19: the three-finger tap for scrolling was hard to
trigger, though the drawn hand showed it. Two causes in the log:

- The thumb meets the index a tracker frame or two (55 ms each) before
  the middle, and a ray pinch's press went out at once, so the middle
  joined too late: 4 of 10 tries clicked and dragged the screen. Now,
  with the middle tip already within 5 cm of the thumb, the press waits
  up to POINTER_RAY_THREE_WAIT (110 ms) for it. The aim is locked, so the
  click lands where it pointed; a pinch with the middle away clicks at
  once.
- ft-hands ends its index pinch as the thumb rolls onto the middle tip,
  and calls that a middle pinch only with the thumb 1 cm nearer the
  middle, so scrolls ended after 0.1 s. A three-finger pinch (ray or
  gaze) now goes on while the thumb is still on either finger, and ends
  once it has left both.
