Case contract

Sprint results. results rows are [name, time] where time is seconds with up to three decimals, or "DNF"/"DQ". Times are rounded up to the next hundredth for publication. Rank by rounded time then name; equal rounded times share the place and the next place is skipped (1, 2, 2, 4). DNF athletes follow the finishers in name order with place None and time "DNF"; DQ athletes are omitted. Return [place, name, time "S.hh"] rows.

Why this case matters

Result feeds publish hundredths from fully automatic timing and must rank ties consistently.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
boundary shared place skips next	`[[1, "Ade", "10.11"], [2, "Bo", "10.11"], [3, "Cy", "10.20"]]`	`[[1, "Ade", "10.11"], [1, "Bo", "10.11"], [3, "Cy", "10.20"]]`	Failed
