[frontier] Naive RAG chunking splitting atomic facts across boundaries, causing agent hallucination

Pre-process documents into atomic propositions \(self-contained claim sentences\) before embedding, ensuring each retrieved chunk contains complete logical units.

Journey Context:
Standard chunking by character count splits sentences and facts. The 'Proposition' pattern \(from recent retrieval research\) uses an LLM to rewrite documents into discrete, atomic claims—each self-contained with its own context. Agents retrieve these micro-facts rather than document chunks, eliminating the 'lost context' hallucination mode where half a fact is missing.
