  "account": "An appointment assistant needs a reliable way to retrieve healthcare appointment information from various sources without serving outdated or incorrect data. The author advocates for a three-stage retrieval plan to ensure accurate and up-to-date responses. The first stage involves filtering the relevant collection for the clinic, language, and document type. The second stage is a bounded semantic query to retrieve the most relevant chunks of information. Finally, the third stage involves deduplicating the chunks based on content hash and policy key, and re-ranking the survivors with freshness and authority rules before attaching the source context to the response. The author stresses the importance of setting retrieval timeouts, capping the top_k value, and implementing retry budgets for upstream fetches to prevent slow systems from holding patient-facing requests open indefinitely. They also recommend storing separate metadata for effective date, published date, and ingestion date to accurately determine the most recent and authoritative policy.",
  "summary": "Healthcare appointment assistants have a nasty retrieval constraint: the same policy can arrive as a new PDF, a portal export, and a copied scheduling note. If those sources are merged casually, the assistant can answer with a stale cancellation window while sounding perfectly certain. That's dangerous. Short answer: use staged retrieval with explicit collections, bounded queries, and source…",
