scene_probe prints the grid s size, its walkable count, the count reachable from where the fly stands and the count never stood on, draws the ground with the reading it actually used, and names the refusal when there is no grid. trap_hunt carries the same line into every trace line and into the summary, so a stalled walk can be read at a glance: a fly with 719 walkable tiles and 4 reachable ones is fenced in and no re-plan will help it. |
