# gitleaks.yml — Secret scanning in CI using the gitleaks OSS binary.
# Closes A-07 gap (gitleaks/trufflehog in pre-commit + CI).

# NOTE: This runs the upstream gitleaks OSS CLI directly rather than the
# gitleaks/gitleaks-action wrapper. The wrapper requires a paid GITLEAKS_LICENSE
# for organization repositories (and the previous pin referenced a non-existent
# commit SHA, which made the workflow fail at startup with zero jobs). The OSS
# binary is MIT-licensed and free, needs no secret, and gives identical scanning.
