+ * prompt but had NO post-generation number verifier — unlike the briefing
+ * (`briefing-grounding.ts`) and the Coach (`coach-prose-grounding.ts`). The
+ * v1.22 score rewrite enriches the prose (a band→meaning interpretation, both

+ * state are the score itself and its contributor values (each a 0–100), all
+ * already present on the `MetricSignal`. A miss does NOT block — the caller
+ * falls back to the always-grounded deterministic text, keeping the locked iOS
+ * `assessment: {text, source, updatedAt}` contract non-empty.
+ *
+ * It grades NUMBERS only (reusing the briefing verifier's `extractNumbers` +
+ * tolerance basis); tone / framing stay the prompt's job. The band→meaning
+ * mapping carries no number, so it cannot be flagged here — and because that
+ * mapping is a closed deterministic table in the deterministic fallback, the
