# M12-06B Status

|
|
|
status: done
|
|
task: compare desktop GLB topology, attributes, materials, nodes, and animations in Web

## Scope
|
|
|
|
The production TypeScript GLB parser now exposes a canonical bounded semantic surface for the five
|
|
M12-06A desktop fixtures. It validates referenced accessors, nodes, materials, textures, skins, and
|
|
animation samplers before returning primitive topology, sorted attributes, PBR material fields,
|
|
node hierarchy/TRS, skin bindings, and animation channels. A field-level comparator checks that Web
|
|
semantics exactly match the pinned Blender 5.2 desktop report.
|
|
|
|
Both Node and a real Chromium Worker consume the exact committed GLB bytes and verify each source
|
|
SHA-256 before comparing all five domains. The existing summary import API remains compatible. This
|
|
task does not create Blender Main data or expose GLB in the file picker; the runtime route remains
|
|
`BLOCKED_UNTIL_MAIN_PERSISTENCE` until M12-06C proves save/reopen and stable IDs.
|
|
|
|
## Evidence
|
|
|
|
- `node --test web/tests/unit/glb-desktop-import.test.mjs` passed 3/3: five exact fixture imports,
|
|
separate domain assertions, and a stable field-level PBR mismatch.
|
|
- `node tools/web/check-glb-desktop-import.mjs` passed: 5 fixtures, 5 compared domains, exact
|
|
desktop/Web canonical hashes, deterministic report regeneration, and the blocked route state.
|
|
- `CHROME_PATH=/usr/bin/google-chrome-stable WEB_TEST_PORT=5425 node_modules/.bin/playwright test
|
|
--config playwright.config.ts --workers=1 tests/e2e/glb-desktop-import.spec.ts` passed 1/1 from
|
|
the `web/` directory using Chrome 150. The Worker verified source SHA-256 and all five semantic
|
|
comparisons.
|
|
- `npm --prefix web run typecheck`, `npm --prefix web run test:status-consistency`, and
|
|
`git diff --check` passed. The package hash remains
|
|
`cfb232baa494ff59f6c8d65514a08c86332ee9354350b2a0392b6f932a7ee42c`.

## Next Task
|
|
|
|
`M12-06C`: create authoritative Main data from the imported GLB, save `.blend`, reopen it, and
|
|
compare stable IDs.
|
|
|
|
## Rollback
|
|
|
|
Remove the canonical Web import surface, report generator/checker, Node/Chromium tests, report,
|
|
manifest, and this status entry. Restore M12-06A as the queue tail and move the machine queue back to
|
|
`M12-06B`. No parity ledger rollback is required.
