# M12-07F Status
|
|
|
|
status: done
|
|
task: STL Web-to-desktop round-trip and material-loss report
|
|
updated: 2026-08-18 America/New_York
|
|
enablingTask: false
|
|
parityStateChange: false
|
|
|
|
## Scope
|
|
|
|
The STL Web path now serializes the bounded parsed triangle result back to deterministic binary STL.
|
|
The loss report explicitly records STL's lack of material slots as
|
|
`STL_MATERIAL_UNSUPPORTED`; it never silently claims material preservation. A Chromium Worker output
|
|
is imported by a fresh pinned Blender 5.2 process and compared by triangle count and facet normals.
|
|
|
|
## Evidence
|
|
|
|
- `node --test web/tests/unit/stl-export.test.mjs` passed 1/1 for binary header/table serialization
|
|
and explicit material-loss warning.
|
|
- `CHROME_PATH=/usr/bin/google-chrome-stable WEB_TEST_PORT=5467 node_modules/.bin/playwright test
|
|
--config playwright.config.ts --workers=1 tests/e2e/stl-web-roundtrip.spec.ts` passed 1/1 in Chrome
|
|
150. Browser output is 184 bytes/2 triangles; Blender reopens 2 polygons/2 triangles with exact
|
|
normals; warning code is `STL_MATERIAL_UNSUPPORTED`.
|
|
- `node tools/web/check-stl-web-roundtrip.mjs` passed:
|
|
`stl-web-roundtrip-ok triangles=2 normals=exact materialLoss=1 desktopExact=true next=M12-07G`.
|
|
- Typecheck and `git diff --check` passed. The STL material loss remains machine-visible and STL UI
|
|
route/parity stays bounded.

## Next Task
|
|
|
|
`M12-07G`: PLY ASCII/binary little-endian capability declarations.
|
|
|
|
## Rollback
|
|
|
|
Remove the STL export/loss protocol, Worker, desktop importer, tests, checker, report, manifest, and
|
|
this status entry. Restore M12-07E as the queue tail and move the machine queue back to M12-07F. No
|
|
parity ledger rollback is required.
