+# M16-GAP-00094 Status
+
+status: done
+task: SMOOTH modifier LOCAL_EXACT slice
+updated: 2026-08-20 America/New_York
+
+scope: Mesh SMOOTH modifier stack exposure for `mesh:WebGapSmoothMesh`.
+
+evidence:
+
+- Desktop fixture exposes `WebGapSmooth` as SMOOTH type code 16 with non-default factor, iterations, axis flags, and vertex group; save/reopen is exact.
+- WASM/Main exposes the same SMOOTH fields as `METADATA_ONLY`; save/reopen is exact.
+- Malformed Blend input is rejected without mutating Main.
+- Generator, npm comparator, and direct comparator exited 0.
+
+knownRisk: Smooth geometry evaluation remains metadata-only; this slice covers modifier stack transport and stable modifier metadata.

+- parent: M16-GAP-00094
+- status: in_progress
+- gap: modifier:SOFT_BODY
+- ownerFamily: MODIFIER
+- targetImplementationClass: LOCAL_EXACT
+
+## 目标
+
+Make the same minimal fixture produce observable modifier:SOFT_BODY data in Blender desktop and WASM/Main, with save/reopen stability. Change only this gap; do not expand to other data-blocks, editors, or browsers.
+
+## 输入与范围
+
+- Fixture: `tests/files/web/generated/M16-GAP-00095-modifier-SOFT_BODY.blend`
+- Generator: `tools/web/generated/M16-GAP-00095.py`
+- Production: `blender-5.2.0/source/blender/web_engine/web_engine_blend_reader.cpp`
+- Checker: `tools/web/check-generated-gap.mjs`
+- Do: field read, desktop/WASM comparison, save/reopen, structured report.
+- Do not: other gaps, Firefox/WebKit, or full editor behavior.
