What
Before a click or cursor move is hit-tested, its point is checked against the list of displays. A point that lands on no display is refused, with an instruction to take a fresh screenshot or move the mouse first, rather than being sent to the OS.
Details
Refusals use the reason code hit_test_off_display.
If listing displays fails or reports zero displays, the check is skipped and the previous behaviour applies, logging "[computer-use] off-display backstop skipped".
Evidence
hit_test_off_display
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
