# W-024 Status

status: done
task: 固定内存和分配策略

## Evidence

- Memory ABI: `web_engine_get_memory_stats()` and scalar accessors
- Golden: `tests/golden/W-024/memory-stats.json`
- Node smoke: `tools/web/run-web-engine-smoke.mjs`

The ABI reports live handles and allocated bytes without exposing WASM heap
pointers to React. Document memory is held inside the engine state and output
buffers are explicitly freed after save; the first mesh snapshot also retains
bounded arrays before the later transferable-buffer path.

## Verification

```text
node tools/web/run-web-engine-smoke.mjs  # blend open/save, then destroy
```
