Primary Path

  • • Mirror and statement normalize to one entry shape
  • • Matching runs strict reference passes before attribute passes
  • • Well-behaved traffic clears straight to Matched

Breaks

  • • Value-date breaks are suppressed until their expected date
  • • Missing items age from value date, not detection time
  • • Aged, unexplained breaks drive provisioning and queries
