name: Claude Code Review
# Dual triggers:
# - pull_request: used for same-repo PRs so the Claude App's OIDC ->
# installation-token exchange succeeds (it rejects OIDC tokens minted
# under pull_request_target with "Invalid OIDC token"). This path posts
# a real GitHub Review with inline comments authored by claude[bot].
# - pull_request_target: used for fork PRs, where secrets are not
# available on the pull_request trigger. This path uses GITHUB_TOKEN
# to bypass the OIDC exchange; findings are issue comments authored by
# github-actions[bot].
# Each job gates on github.event_name AND head.repo so exactly one job runs
# per PR push.
