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.
