How it uses Jev

// Pinned, not `jev-latest`: review thresholds are tuned against one version,
// and the response reports which model answered so every mark is attributable.
export const JEV_MODEL = 'jev-1.13.0'

// Jev's accuracy falls as state fills with irrelevant text, so it never gets
// the whole paper: a window around Claude's proven quote, or the opening of
// the source (the abstract) when there is no quote to anchor on.

export const PASSAGE_FALLBACK_CHARS = 6_000
