Evals & guardrails
- Win-rate and customer-satisfaction tracked per cohort.
- Provisional-credit decisions above a threshold gate on an oversight agent (Reg E).
Frontier edge
- ▲Outcome simulation: forward-runs the chargeback against the network's reason-code logic to predict win probability before filing, so it only contests the cases it can win.
- ▲Voice-native intake: takes the dispute by phone, transcribes and structures the claim in one turn, and reads the resolution back in plain language.
- ▲Eval-gated playbook learning: distils winning-evidence patterns per merchant category from settled cases, promoted only after backtesting against historical outcomes.
