314A successful exchange returns an `access_token` beginning with `sk-ant-oat01-` and an `expires_in` value in seconds. A denied exchange returns an opaque `401` `authentication_error` with the fixed message `Authentication failed`, whichever check failed; in most cases the deny reason is recorded on the attempt's entry in the [authentication history page](https://platform.claude.com/settings/workload-identity-federation?tab=history) in the Claude Console, and [Troubleshoot a failed exchange](https://platform.claude.com/docs/en/manage-claude/wif-reference#troubleshoot-a-failed-exchange) walks the checks in order. The most common GitHub Actions-side cause is the `sub` claim format not matching (its trailing segment varies between `ref:...`, `environment:...`, and `pull_request` events); the history entry shows reason `match_subject_prefix`.
