+
+status: done
+task: LATTICE modifier LOCAL_EXACT slice
+updated: 2026-08-20 America/New_York
+
+scope: Mesh LATTICE modifier stack exposure for `object:WebGapLatticeModifierObject`.
+
+evidence:
+
+- Desktop fixture exposes `WebGapLatticeModifier`; save/reopen is exact.
+- WASM/Main exposes LATTICE type code 2 and metadata parameters on the mesh scene node.
+- Malformed Blend input is rejected without mutating Main.
+- Generator and npm comparator exited 0.
+
+knownRisk: Lattice deformation evaluation remains metadata-only; this slice covers modifier stack transport and metadata.

+nextTask: `M16-GAP-00076`

+## 目标
+
+Make the same minimal fixture produce observable modifier:LINEART 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.

+- 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.
