OUTCOME + OUR CALL
Official outcome: Not flown yet / not resolved
Our final pre-flight call was UNCLEAR at 35% confidence, T-9d 12h. It will be scored once the official outcome is in.
Scoring rule: a launch that reached flight means the countdown proceeded, so a GO or HOLDING call is right and a SCRUB call is a false alarm. Only the last call made before T-0 counts.
