Why an agent can trust this route.
Sonar evidence is advisory. Paid delivery is shown as verified only when paid probes are available; otherwise route estimates use the unpaid handshake as a clearly labeled proxy.
Observed outcomes
ROX index as (SpO2 percent / FiO2) / respiratory rate in breaths/min (Roca 2016). Returns the index rounded to two decimals. Not a ventilation order. This is not the PaO2/FiO2 (P/F) ratio and not RSBI (respiratory rate / tidal volume).
