task: SUBSURF modifier LOCAL_EXACT slice
updated: 2026-08-20 America/New_York

scope: Mesh SUBSURF modifier stack exposure for `mesh:WebGapSubsurfMesh`.

evidence:

- Desktop fixture exposes `WebGapSubsurf` as SUBSURF type code 1 with SIMPLE subdivision, viewport level 2, and render level 3; save/reopen is exact.
- WASM/Main exposes the same SUBSURF stack entry and matching subdivision parameters; save/reopen is exact.
- Malformed Blend input is rejected without mutating Main.
- Generator, npm comparator, and direct comparator exited 0.

knownRisk: Subdivision geometry evaluation is unavailable in this build without OpenSubdiv; this slice covers modifier stack transport and base metadata only.
