[synthesis] How do production RAG products chain search, synthesis, and citation so answers feel reliable rather than invented?

Use search → extract snippets → rerank by answerability → synthesize with inline citations mapped to source IDs → answer with citation fallback. Never ask the model to hallucinate URLs; ground every claim in retrieved snippets.

Journey Context:
Perplexity's API behavior shows citations are not post-hoc decorations but first-class IDs that survive the entire pipeline. The common failure mode is generating fluent prose and then stapling citations onto it, which yields hallucinated links. The right decomposition is to force the model to cite snippet IDs during generation, then render them. Reranking before synthesis is the critical step most tutorials skip — it reduces context pressure and improves precision. Multiple search backends are cheap insurance against any single index being stale.
