/**
 * classifierScorer — an {@link EntryScorer} whose ranking IS a calibrated
 * classifier's distribution (9.104.0; docs/design/2026-09-scored-choice.md
 * step 2, opened when a provider that scores came in reach).
 *
 * `keywordScorer` and `embeddingScorer` compute a raw score per candidate
 * and let `rankEntries` soften it into a `relevance` share. This scorer has
 * no raw score to soften: the classifier is asked ONE `choice` question
 * over the candidates — criteria `{ id: description }`, declared before the
 * call, the same law as declared tags and routes — and answers with a
 * probability per candidate and a pick. Both are the provider's data and
 * both land on `EntryScoring` unchanged: `ranked[].score` and
 * `ranked[].relevance` are the SAME number (the probability as sent, never
 * renormalised), and `chosen` is the provider's `choice`, not an argmax the
 * library took — a provider whose pick differs from its own argmax is
 * recorded as it answered, which is a fact about the provider.
 *
 * A provider failure is NOT a guess: the scorer returns
 * `scorer: 'classifier:unavailable'`, an EMPTY ranking and no `chosen`.
 * `stages/pickEntry.ts` leaves the cursor unset on an undefined `chosen`
 * and the Injection Engine's cold-start entry pick takes over — the
 * fallback that already exists for a throwing embedder, reached here
 * through the honest empty result rather than a throw.
 *
 * Pure core of the skill-graph fence: the only import outside the folder
 * is the `Classifier` port type (`src/classify/types.ts`, a zero-import leaf).
