# M12-06G Status

status: done
task: GLB import/export cancellation, Worker restart, and OPFS quota recovery
updated: 2026-08-18 America/New_York
enablingTask: false
parityStateChange: false

## Scope

Schema-1 GLB recovery receipts now bind operation, worker generation, source/output SHA-256,
revision, temporary bytes, live requests, commit state, and stable cancellation/restart/quota codes.
Both import and export cancellation release all temporary bytes and publish no result. A new Worker
repeats the same bounded GLB import with an identical semantic result hash.

The GLB asset persistence path uses the existing content-addressed OPFS store. A real Chromium
origin quota of 64 KiB rejects a 128 KiB candidate, while the previously committed GLB remains
readable after Storage Worker restart. Raising the quota allows a small follow-up asset to commit.

## Evidence

- `node --test web/tests/unit/glb-recovery.test.mjs` passed 2/2 for cancel, quota, commit, and
  generation transition invariants.
- `CHROME_PATH=/usr/bin/google-chrome-stable WEB_TEST_PORT=5455 node_modules/.bin/playwright test
  --config playwright.config.ts --workers=1 tests/e2e/glb-recovery.spec.ts` passed 2/2 in Chrome
  150. The first real-quota run reached the expected browser failure but the assertion only accepted
  the injected error wording; the final run accepts both native and injected quota messages.
- `node tools/web/check-glb-recovery.mjs` passed with
  `glb-recovery-ok cancelled=2 workerGeneration=2 quota=GLB_OPFS_QUOTA smallRecovery=true next=M12-07A`.
- `npm --prefix web run typecheck`, `node --check tools/web/check-glb-recovery.mjs`, and
  `git diff --check` passed. The package manifest remains unchanged.

## Next Task

`M12-07A`: OBJ single-Mesh positive fixture covering position, normal, UV, and material group.

## Rollback

Remove the GLB recovery receipt, quota fault option, Worker/browser adapter, tests, checker, report,
manifest, and this status entry. Restore M12-06F as the queue tail and move the machine queue back to
M12-06G. No parity ledger rollback is required.
