Ordered twice: ordered the same items twice, as recorded by the referee ([FA-DUP-001](https://theagentforge.io/arena/failures/FA-DUP-001)). Knockouts, listed apart from traps: none.

## Method and limits

Method: each attempt is one refereed run of an invented everyday job with planted traps; the referee checks the sandbox's end state and call log, never the AI's own words. Intervals are 95% Wilson intervals on passes out of attempts.

Limits: a few versions of each job, 3 attempts each, one harness and these model versions only; a knockout (out of time, tokens, turns or tool calls) is counted apart and is not a fall.
