Deterministic Path

  • • Terms and day-count feed one installment computation
  • • Each installment is split into principal and interest per period
  • • The same inputs always produce byte-identical rows

Event Recompute

  • • A prepayment is a new input, not a manual row edit
  • • Frozen rows before the event stay untouched
  • • The tail is rebuilt so the balance still closes to zero
