Invalid polygonal output from Douglas-Peucker simplification and densification was still repaired with the legacy
buffer(0)workaround. This can discard valid geometry thatGeometryFixeris designed to preserve.This change routes both validation paths through
GeometryFixer, keeps the existing validation opt-outs, and preserves Douglas-Peucker's historicalPOLYGON EMPTYresult for collapsed polygonal output. Regression coverage verifies preserved lobes and holes outside a shell.Tests:
