Module contamination 

2026-09-26: Cross-contamination benchmark: concurrent requests must not change each other’s output. score holds the leg design and the classification, prompts the probe corpus, and driver the state machine that runs the legs.

Owner: bench (contamination). Invariants: none beyond the types.

Modules

driver

2026-09-26: The contamination state machine. Each next() runs one step (endpoint probe, a leg, or scoring), so the pane updates as each leg lands and a cancellation is seen before the next step.

prompts

2026-09-26: The probe corpus: prompts built so that contamination is detectable.

report

2026-09-26: How a contamination run is presented: the probe-by-leg table, the summary tiles and the gate metrics, each a pure function of a Score.

score

2026-09-26: Scoring for the contamination benchmark: classify every prompt at every rung and in the post-check against its own solo reference. The module reads no handle, network or clock; score_tests.rs tests it with in-memory outcomes.

transcript

2026-09-26: Re-export of benchmarks::transcript for the contamination module’s super::transcript imports. The ssm_poison, scheduler_equivalence and kat_equality drivers use the same type, so every driver shares one equality contract.
