Method and scope
Constructs impossible variants of coding tasks and examines specification-violating passes.

- Benchmark
- Assessment subject
- The model or agent in the stated task configuration.
- Primary dimension
- Propensity
- Evidence snapshot
- 2026-10-29.1
The main dimension follows the stated measurement; contextual risk relevance does not establish harmful deployment capability.
Source finding
Cheating rate (pass@1 on impossible variants): 1.5 %. Conditions are retained from the source.
Limitations
The cheating rate is conditional on contradictions, test access and scaffolding; it is not a general dishonesty rate.
Only LiveCodeBench split, not Impossible-SWEbench. Figure does not expose separate oneoff/conflicting breakdown or denominator.
