# M16-GAP-00088 Status

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

scope: Mesh PARTICLE_SYSTEM modifier stack exposure for `mesh:WebGapParticleSystemMesh`.

evidence:

- Desktop fixture exposes `WebGapParticleSystem` as PARTICLE_SYSTEM type code 19; save/reopen is exact.
- WASM/Main exposes PARTICLE_SYSTEM type code 19 and base metadata parameters on the mesh scene node.
- Web legacy particle pointers remain metadata-only and physics manifest is safely empty for this fixture.
- Malformed Blend input is rejected without mutating Main.
- Generator, npm comparator, and direct comparator exited 0.

knownRisk: Legacy particle simulation and ParticleSettings linkage are unavailable in Web; only modifier stack transport and base metadata are covered.
