Cheap to expensive

  • • Stages run in cost order and fail early
  • • Each check emits a signal, not a verdict
  • • A weak signal alone never decides the case

Graded decision

  • • One calibrated score maps to three bands
  • • The refer band routes ambiguity to a human
  • • Every signal is persisted for replay and audit
