Report, dialog and diagnostic text across post verification, cutoff
planning, alignment and cutting-plan review repeatedly told the user
what checks weren't (safety certifications, proof, guarantees) instead
of what to do. Reworded these to state the same caveats affirmatively
(inspect X, confirm Y, review Z) without changing the underlying
safety guidance, and updated the tests/docs that pinned the old wording.
Add DrawingAligner: bounded multi-start rigid ICP that maps a revised
drawing's geometry into the old drawing-local frame as an operator-review
seed. Material-filtered programs flatten through the shared chord-error
machinery, resample via the shared ContourSampler ring scheduler, and fit
closest bounded target segments with trimmed weighted least squares
(reflection never solved, never applied). Seeds come from outer-centroid
translation and MBR angle deltas with the 90-degree family plus identity.
The stable outer boundary is fitted first; retained hole evidence only
reorders candidates inside the outer tie band, so a moved hole cannot
drag the perimeter. Structured AlignmentResult reports convergence,
residual quantiles, bidirectional coverage, symmetry ambiguity,
reflection uncertainty, and a bounded diagnostic IoU. Refusals
(invalid input, insufficient support, unsupported topology, sample
budget, cancellation) are reported as reasons, not thrown.
Tests verify recovered poses against exact fixture geometry (true
segments/arcs/circles, not sample clouds) for known transforms,
symmetric rectangle/circle ambiguity, mirror non-selection, moved-hole
perimeter preservation, and bounded region arithmetic (identical=1,
disjoint=0).
