# M16-GAP-00033 Status

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

scope: BOOLEAN modifier identity, Difference operation, Exact solver and cutter target linkage for `mesh:WebGapBooleanObjectMesh`.

evidence:

- Desktop fixture exposes `WebGapBoolean` with Difference/Exact settings and stable cutter target; save/reopen is exact.
- WASM/Main exposes the same modifier parameters and target dependency from the same fixture; save/reopen is exact.
- Malformed Blend input is rejected without mutating Main.
- `npm --prefix web run test:generated-gap -- --task M16-GAP-00033` and `node tools/web/check-generated-gap.mjs --task M16-GAP-00033` exited 0.

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