Censoring and survivorship
Use "Survivorship bias is the same trap from the other side" to describe the practical rule.
Step 1 of 2
Censoring and survivorship
An aborted or still-running agent turn is right-censored: you know it took at least this long, not how long it finally took. Treating it as a completed fast request or dropping it, both bias you toward looking healthier than you are. Survivorship bias is the same trap from the other side: if only successful runs reach the table you analyze, your success rate is a tautology.
Don't compute success rate over only the runs that produced a final event. The runs that hung, timed out or were killed are the failures you care about and they're the ones most likely to be missing from a naive table. Always reconcile your denominator against admitted attempts, not completed ones.
