Marc-André BombeckandClaude Opus 4.7 53aade981a feat(ai): post-validation logs citation-coverage rate per insight generation
After the schema parse and citation cross-check pass, the wrapper
counts how many recommendations make a normative claim ("target",
"should", "normal range", "above", "below") and how many of those
carry a `referenceId` pointing into the curated medical-reference
bundle. The result lands in the active Wide-Event meta annotation
under `ai_total_recommendations`,
`ai_normative_recommendations`,
`ai_cited_normative_recommendations` and
`ai_uncited_normative_recommendation_ids` so the admin AI quality
dashboard can chart citation-coverage over time.

Observational only in v1.4.16 — a normative rec without a referenceId
is logged, never raised as a parse error. Phase B5c will flip the
check to required for severity >= "important".

15 unit tests pin the keyword heuristic (EN + DE), the coverage
counts across cited / uncited / observational mixes, and the
`generateInsight()` integration that emits the annotation only on
success (skipped on schema-failure throw).
