Perception never fired

A running brain has waited longer than the stuck time in a state whose transitions or child conditions read perception, and no candidate was seen. Evidence includes the latest sight checks (occluded, outside the cone, out of range).

#Common causes

• The target is outside the Perceiver's range or field of view, or line of sight is blocked.
• The Stimulus has visibility 0 or another kind than the behaviour asks for.

#Fixes

• Adjust Perceiver range/FOV/eye height or the NPC's facing.

• Check Stimulus kind and visibility, and the line-of-sight geometry.
