The hex dumps from the on-glass session show textbook SS_TOUCH packets with pressureOrDistance = 0x7fc00000 (NaN): VoidLink encodes 'unknown finger pressure' as NaN (iPad fingers have no force sensor), and the anti-forgery finiteness gate rejected the entire packet — silently disabling the touch plane while pen (real Pencil force, always finite) worked. Coordinates keep the strict gate (they feed injector scaling); pressureOrDistance now sanitizes non-finite to 0.0, the spec's own 'unknown', which the pen path already maps to full-scale ink on contact.
