ajandClaude Opus 5.5 f4317bc52f fix(planning): learn to reach a sheet separator from beyond the parts in its way
A sheet separator is cut after everything, so when the approach to its
pierce crossed parts already cut, the usual "cut it before them" rule
contradicted that and the search learned nothing. It fell back to the
full search, which spent the budget or found a route that climbed the
column and jumped back down past the cut parts (N26-23M).

When every "cut the blocked part first" rule would contradict a required
order, learn the other way round: cut the part the approach left from
before the parts it crossed, so the tool arrives from beyond them. A
separator blocked this way now ends the attempt at once, like any
cutoff whose rule can be learned.
