 **Read this before relying on the documents numbers.** The gain is measured **in distribution**: training and every documents suite share one source (CFPB complaints) and the same two question templates. It shows Kev-4B learns real long documents from a few thousand labelled examples; it does not show the same gain on other kinds of documents. Evaluation labels are AI-adjudicated (a unanimous three-model judge panel, or two agreeing adjudications) and human spot-checked (47/50 and 50/50).

+- Hub: `jaredpalmer/kev-4b` (this repo; trial `r8-small/00-trial-0`; the registration and every read are in `PLAN.md` round 8 on the `research/overnight-r6` branch). The previous version is at tag `night2-du-release`; the pre-delta v7 checkpoint at `v7-base`; the Qwen3 generation at `qwen3` ([its card](kev-4b-qwen3.md)).

The release was decided by a rule registered before any read (`PLAN.md`, round 8): documents development lower bound > 0, short-state and external guards sized to what each suite can resolve, then one read of the untouched documents test and one locked read. A first seed (round 7) gave the same documents gain and failed only per-suite lower bounds on the two smallest suites; it was not released.

 **Calibration.** The delta sharpened the raw logits (fitted temperature 2.14 → 2.96; raw out-of-domain Brier 0.327, raw locked Brier 0.278). As served, calibration is unchanged. `KEV_TEMPERATURE=1.0` gives the raw values.
