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

scope: Mesh MESH_CACHE modifier stack exposure for `mesh:WebGapMeshCacheMesh`.

evidence:

- Desktop fixture exposes `WebGapMeshCache` as MESH_CACHE type code 46; save/reopen is exact.
- WASM/Main exposes MESH_CACHE type code 46 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: Mesh Cache evaluation and external cache loading remain unavailable; this slice covers modifier stack transport and base metadata.
