Day 3, 16,400 ft: How we made the call to turn back.
A six-participant cohort. A weather window closing faster than the forecast predicted. One participant whose SpO2 wasn't recovering between rest cycles. This is the actual decision tree we ran — written by the lead guide who called it — and what every cohort member said about it at the AAR seven days later.
Includes the inReach log, the go/no-go criteria we set at base camp, and the conversation we had at the evening debrief that night. No hero narrative. No "we summited anyway." Just the call.
