This PR hardens the organization's CI pipelines by removing committed secrets from the check workflow.

Hardcoded Secrets Removed: Updated .github/workflows/check.yaml to remove committed issuer and verifier private-key literals, as well as the placeholder ANTHROPIC_API_KEY value.

Ephemeral Keys: The workflow now generates example signing keys ephemerally at runtime using the repository’s existing secret-generation helpers (examples/issuer/bin/secret and examples/verifier/bin/secret), exporting them strictly for the duration of the job.

Summary by CodeRabbit

  • Chores
    • Improved automated workflow security by preventing checkout credentials from being persisted and limiting sensitive credentials in the workflow environment.

Walkthrough

The check workflow removes three job-level secret environment variables and disables persisted checkout credentials. Push and pull-request triggers, setup, build, and check steps remain unchanged.

Changes

Workflow Security Configuration

Layer / File(s) Summary
Harden workflow credentials
.github/workflows/check.yaml
The workflow removes ANTHROPIC_API_KEY, ISSUER_PRIVATE_KEY, and VERIFIER_PRIVATE_KEY from the job environment. The checkout step sets persist-credentials: false. Existing triggers and build/check steps remain unchanged.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🔵 Low · up to f1d05

The workflow removes committed secrets and generates temporary keys, but incorrect newline characters remain in the CI configuration and could cause validation or check failures. The PR is mergeable with explicit owner awareness and follow-up on the YAML formatting issue.

Disable Git credential persistence unless this job needs Git writes.

actions/checkout@v4 persists GITHUB_TOKEN in the local Git configuration by default. The later build and check steps execute repository code. Set persist-credentials: false. If a later step requires Git writes, grant the minimum permission and provide the token only to that step.

In @.github/workflows/check.yaml:
- Line 1: Normalize the complete check workflow file to LF (\n) line endings
instead of CRLF, preserving its YAML content, then rerun YAMLlint to verify the
newline-format error is resolved.
- Around line 15-17: Remove the committed ANTHROPIC_API_KEY, ISSUER_PRIVATE_KEY,
and VERIFIER_PRIVATE_KEY values from the workflow; generate the signing keys at
runtime using the existing helpers, and only configure the API key if the checks
actually require it. Rotate either private key if it has been used outside
isolated tests.
