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.
