Usage:
  orly db repair [options]

Options:
  --dry-run, -n   Preview repairs without making changes
  --help, -h      Show this help message

Environment variables:
  ORLY_DATA_DIR          Database data directory
  ORLY_DB_LOG_LEVEL      Logging level

The repair operation fixes integrity issues found by health check:
  - Rebuilds missing serial->eventID mappings from compact events
  - Removes orphaned serial->eventID mappings
  - Reports pubkey serial inconsistencies

WARNING: Always backup your database before running repair.
         Use --dry-run to preview changes first.`)
