+2. On each GPU machine, check out the PR head and build/install its candidate
+   wheel and native tests. Authenticate with `gh auth login` using an account
+   permitted to write commit statuses.
+3. Run your validation command, including GPU tests, `../ct2-eval`, and benchmarks:

+   ```bash
+   bash release-check.sh cuda PR_URL COMMAND [ARG...]

+The script checks that tracked files are clean and HEAD matches the PR. It

+The backend argument only labels the status; configure GPU execution yourself.
+Your command must fail on regressions or missing GPU coverage. Compare against
+the previous release on the same hardware. Detailed output stays in the terminal.
+
+Configure both statuses as required checks for release PRs. Re-run validation
+for every new commit. Publish the validated artifacts after CI and both GPU
+checks pass; validate again if the final release changes the tested code.
