Do the camera-resistant screens work?
Designed, not yet built
Short answer
REQ-3304 is a high-priority requirement for all three tiers: camera-resistant screens must use side-angle privacy filtering and the refresh-pattern measure; effectiveness against real cameras is untested and must not be claimed until measured. This is on the design side of the line. Nothing in v0.2.0 does it. To verify it, the specification says no marketing claim exists without lab data; measurement plan exists.
This is designed, not built.
