Sealed local class: optin-gaze-or-gesture
Hypothesis: an opt-in local mark can be hashed without recording the gesture, gaze point, or any video frame.
Confidence (design-material weight only): low–medium. Status: unattested.
The persistence sentence is discarded and is not in the hash. An opt-in mark is not a recorded track and not a remote input.
