status: done task: DECIMATE modifier LOCAL_EXACT slice updated: 2026-08-20 America/New_York

scope: DECIMATE modifier metadata and collapse parameters for mesh:WebGapDecimateObjectMesh.

evidence:

Desktop fixture exposes WebGapDecimate with ratio 0.65, two iterations, collapse mode, and angle limit 0.4; save/reopen is exact.
WASM/Main exposes the same modifier parameters from the same fixture; save/reopen is exact.
Malformed Blend input is rejected without mutating Main.

knownRisk: Full evaluated decimation geometry and editor mutation remain outside this metadata/local-exact modifier slice.
