Web Dependency Matrix

This is the initial dependency decision for the browser build. A dependency may move from 待验证 only after a task adds a build or browser regression test.

Dependency or module	Decision	Web role	Evidence or next task
blenlib, guardedalloc	保留	Blender base/runtime utilities	W-022
makesdna, makesrna	保留	DNA/RNA data and property schema	W-022
blenloader, blenkernel	保留	.blend read/write and data blocks	W-022, W-030
bmesh	保留	mesh editing and Decimate primitives	W-022, W-074
depsgraph	保留	hierarchy, modifiers, evaluated mesh	W-067, W-093
selected modifiers	保留白名单	Blender 5.2 types are identity-complete; evaluated parity remains fixture-gated	modifier support matrix, W-066, W-074
windowmanager, editors, ghost	React replacement	Blender-style UI semantics, not desktop window backend	W-018, W-019
Blender draw/gpu viewport	关闭首期	Three.js is the browser renderer	W-013, W-050
Python runtime and automatic .blend scripts	关闭首期	security and package-size boundary	W-117
Cycles, CUDA/OptiX, Embree	关闭首期	server-side or native rendering only	roadmap non-goal
OpenVDB	浏览器关闭；桌面/服务端转换目标保留	真实 OpenVDB 13 -> NanoVDB 32 desktop/server 转换；不得链接进浏览器 WASM	N-015 VDB-010~014，native/server hash 等价门
NanoVDB	浏览器仅消费格式	HTTP/OPFS 分块 + Float32 WebGPU sparse volume；双生产视口已接入，demand paging/material/golden 阻断	N-015 VDB-003~034
USD, FFmpeg	关闭首期	server-side or later format modules	W-021
React + TypeScript	保留	application UI and state	W-010
Three.js (vendored)	保留	WebGL2 viewport and scene adapter; runtime has no CDN dependency	W-013, W-050
Emscripten runtime	保留	Blender C/C++ to WebAssembly	W-020~W-025
zlib 1.3.1 (vendored)	保留	gzip .blend decompression in Blender file reader	W-030
zstd 1.5.7 (vendored)	保留	zstd .blend decompression in Blender file reader	W-030
IndexedDB	保留	project metadata and small persistent records in StorageWorker	W-014, W-041
OPFS	保留	large .blend, assets, snapshots and LOD cache	W-040, W-077

No CAD kernel or Bitbybit/OCCT module is part of this matrix.
