usage() {
cat <<'USAGE'
Usage: sudo ./lint-db.sh [options]
Purpose:
Non-destructively lint a rebuild DB for structural problems that can pollute
restore results.
Checks:
- backup directories captured into DB (e.g. *.bak.*)
- nested duplicate service roots (e.g. nginx/nginx, i2pd/i2pd)
- overlapping category roots (e.g. etc-i2pd plus sibling tunnels.d)
- duplicate canonical files at two depths within the same category
Options:
--db-dir PATH
--verbose
--help
