wasm mesh tools, anchored comments, presence cursors
Walkthrough
This week we put more work in the browser and more people in the scene. Local WASM mesh tools, remesh, decimate, and cleanup, now run in-tab as ordinary proposals, which means cleanup is free, reviewable at the gate, and undoable like everything else. On the collaboration side, real-time presence arrived: join a shared scene-core session and you see live cursors, selections, and who is editing what, with follow-to-viewport for jumping to a collaborator. Comments anchor to specific nodes or positions so feedback sticks to geometry instead of floating in a side channel.

Engine
- concurrent proposal orderingthe shared command API serializes edits from multiple cursors so simultaneous proposals apply in a deterministic order
- in-browser mesh pipelineWASM mesh operations feed their results back through the same proposal path as any human edit, keeping one history
- anchored annotation storecomment threads bind to node ids and positions in scene-core and survive transforms and re-imports
UI
- presence layeran overlay showing collaborator cursors, names, and active selections without cluttering the viewport
- comment thread panela side panel listing anchored threads with resolve state, jumping to the anchored geometry on click
