# W-039 Status

status: done_current_scope
task: 完成场景数据里程碑

## Current gate

The `.blend` -> Blender Main/WASM -> binary SceneIR -> Three.js path is proven
for basic, animation, pose, modifier, resource and authoring fixtures. The
browser opens files, renders geometry, keeps Outliner/viewport selection linked,
and applies Main edits with revisioned snapshot/delta responses.

## Accepted bounded scope

W-034 through W-038 are complete for the declared bounded contract: binary
SceneIR, resource deltas, packed assets, animation editing and Blender Main
authoring all have native and browser regression evidence. New Blender
families must add independent goldens instead of reusing W-080.
