# M14-01D Status

status: done  
task: probe identity and GPU/OS adapter recording  
updated: 2026-08-19 America/New_York  
enablingTask: false  
parityStateChange: false

## Scope

The production Chromium probe records observed browser identity, OS kernel/runtime identity,
hardware concurrency, WebGL2 vendor/renderer/version, WebGPU adapter identity, and cross-origin
isolation. WebGPU is recorded as `BLOCKED/WEBGPU_ADAPTER_UNAVAILABLE` in this headless environment;
the result does not claim WebGPU support. The report is bound to the exact worker/WASM asset hashes
used by the probe and carries a canonical identity SHA-256.

## Evidence

- `npm --prefix web run build` passed.
- `npm --prefix web run test:probe-identity` passed twice (one report-generation run and one frozen
  report verification run).
- Checker output: `probe-identity-ok version=151.0.7922.34 os=linux/x64 webgl2=PASS,webgpu=BLOCKED identity=3c6f898e1b6ffd39862505b8e7dde8fd29369204e1670a013859f74ccaf1c1eb execution=DISABLED next=M14-01E`.
- `git diff --check` passed.

## Next Task

`M14-01E`: Chromium WebGPU fail-closed boundary. Firefox and WebKit are excluded by the project
Chromium-only iron rule.

## Rollback

Remove the probe checker, report, manifest, package command and this status/task entry; keep
`M14-01C` as the queue tail.
