Classification scope and review notes

Polyline simplification. The main checks one call of perpendicular-distance reduction against endpoints and an independent interpolation bound, and plots the original and reduced curves. Separate GNU 16 probes confirm incorrect radial-distance filtering and lost endpoints on consecutive perpendicular-distance calls at this pin; see the retained reproducers. The single-call example does not fix those upstream limitations.

Reviewed procedures

These mappings have pinned source evidence. A checked package example may exercise only some of them; source review is not a numerical benchmark.
