# Full-history verified-secret scan. gitleaks runs diff-scoped in pre-commit
# (see .pre-commit-config.yaml); this is a periodic sweep of the entire commit
# history with a different engine and its own detector set, catching anything
# a diff-scoped scan by construction cannot (a secret introduced and later
# removed in the same PR still shows up in history). Also runs on push and
# pull_request so every change is swept, not just the weekly schedule.
