Fairness Audit Log

RoomTab's Logic Engine is rigorously tested against verified scenarios to ensure mathematical fairness. Below is the live audit of our core logic principles.

Scenario 1: The "Vegan" Exclusion

Rule: If a user excludes themselves from a shared item, they pay $0.

Input Context
"Pizza Night ($60). Alice didn't eat any pizza."
Audit Result
  • Alice: $0.00 (pass)
  • Bob: $30.00
  • Charlie: $30.00

Scenario 2: The "Late Mover" (Pro-rating)

Rule: Rent splits must be weighted by duration of stay.

Input Context
"Rent $3000. Bob stayed 15 days (others 30)."
Audit Result
  • Alice: $1200.00
  • Charlie: $1200.00
  • Bob: $600.00 (50% reduction)

Scenario 3: Settlement

Rule: The payer must be reimbursed the exact difference.

Input Context
"Dinner $90. Alice paid full. Split equally."
Audit Result
  • Split: $30 each.
  • SETTLEMENT: Bob pays Alice $30.
  • SETTLEMENT: Charlie pays Alice $30.
