- undo-redo: describe the heaviest nests by size instead of job numbers;
name the Nest > Edit dialog rather than the internal 'Nest Info'
- cutting-planner: clearing lead-ins and cut-offs is now undoable
- nest-storage: drop the internal D4 label and the nonexistent
Nest > Nest Info menu path
Undo/Redo landed in phases 1-3 without a written contract, so the next
person adding a desktop edit has no rule telling them to record it, and
nothing explains why a restore must close Cutting Inspection or why
snapshots keep empty plates and skip best fits. docs/undo-redo.md states
what is and is not undoable, the BeginChange/RecordChange rule, the
"Change" safety net, how states are captured and restored, the guards
and key routing, and the measured limits. AGENTS.md links it from the
OpenNest bullet and the contract list.
