{
  "note": "process_creation telemetry (CommandLine). The rule hunts destructive shell/DB/availability commands via '1 of selection_*', so one representative command from each of the three selection groups must match. Benign commands — including a plain 'rm' without the recursive/force flags — must not. (The rule's own false-positive note documents that lowercase coreutils 'truncate' DOES share the TRUNCATE token and must be allow-listed, so it is intentionally not used here as a negative.)",
