 - **Reported cost and speed (vendor):** about 70–500 ms per call; input billed (about $0.042 per million input tokens for Jev 1.13), output free.
 - **Limits:** text only, English-first, no explanations, no generated text. Early access with changing rate limits. It receives whatever is in `state`, so secrets must stay out.
 
+**Verified 2026-10-27** (`TestProbeScoreAndNoulAgainstLiveAPI`, jev-1.14.0, 0.17 s, 466 tokens, one mixed call): `score` returns score/confidence/legend/probabilities as documented (severity 1.95 of 2, conf 0.93); `noul` returns only `noul` (0.94), **no confidence** — strategies 3 and 4 must threshold noul directly (docs suggest yes 0.7 / no 0.3, middle to review). Confidence is distribution concentration as warned: the split doc example (0.35) matches our probe's concentration reading.

 **Crows today** uses one call with two `choice` questions (mode, task type) and a single global threshold of 0.7 (`jev.go`). So **custom labels are supported**, which answers spec open question 2: expectation checks and orchestration checks are just more questions.
