M12-06B Status

status: done task: compare desktop GLB topology, attributes, materials, nodes, and animations in Web updated: 2026-08-18 America/New_York enablingTask: true parityStateChange: false

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.
