# M16-GAP-00077 Status

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

scope: Mesh MASK modifier stack exposure for `mesh:WebGapMaskMesh`.

evidence:

- Desktop fixture exposes `WebGapMask` as MASK type code 27; save/reopen is exact.
- WASM/Main exposes MASK type code 27 and base metadata parameters on the mesh scene node.
- Malformed Blend input is rejected without mutating Main.
- Generator, npm comparator, and direct comparator exited 0.

knownRisk: Mask evaluation remains unavailable; this slice covers modifier stack transport and base metadata.
