# The reviewer only needs to read the diff and post comments — contents stays
# read-only, which is the fork-PR hardening that matters (fork PRs never
# receive the OAuth token secret either). id-token: write is required:
# claude-code-action fetches an OIDC token at startup even with OAuth-token
# auth, and without the grant the action dies before the review starts.

# Any GitHub user can comment on a public repo, so the @claude trigger must
# be gated to people we trust with the workflow's write permissions.
# OWNER only fires on user-owned repos — this is an org repo, where org
# members report MEMBER — so MEMBER is the arm that actually admits the
# maintainers. It covers ANY org member (including read-only ones); fine
# for a small org, but swap in a `gh api .../permission` gate step if the
# org ever outgrows the set of people who should hold contents: write.
# The gate trusts the COMMENTER, not the content — a trusted commenter can
# still point @claude at untrusted PR text; that residual is inherent.
