# Arbiter sanity gate

The arbiter (ollama:kimi-k2.6:cloud) was run against a held-out 65-case slice of the oracle corpus whose true category is stamped. Each case is a known planted cheat, so agreement is the fraction the arbiter independently labeled `true-cheat`. This is a floor check on whether the arbiter can recognize a genuine cheat; it is not a measure of real-PR accuracy.

- Agreement: **92.3%** (60/65)
- Threshold: 75%
- Result: **PASS**
- Run at: 2026-06-02T00:02:13.336Z
