# M16-GAP-00098 Status

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

scope: Mesh SURFACE modifier stack exposure for `mesh:WebGapSurfaceMesh`.

evidence:

- Desktop fixture exposes `WebGapSurface` as SURFACE type code 30; save/reopen is exact.
- WASM/Main exposes the same SURFACE stack entry with matching generic visibility flags; save/reopen is exact.
- Malformed Blend input is rejected without mutating Main.
- Generator, npm comparator, and direct comparator exited 0.

knownRisk: Surface deformation evaluation remains metadata-only; this slice covers modifier stack transport and base metadata only.
