# M16-GAP-00090 Status

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

scope: Mesh SCREW modifier stack exposure for `mesh:WebGapScrewMesh`.

evidence:

- Desktop fixture exposes `WebGapScrew` as SCREW type code 34; save/reopen is exact.
- WASM/Main exposes SCREW type code 34 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: Screw geometry evaluation remains metadata-only; this slice covers modifier stack transport and base metadata.
