[synthesis] Error propagation across multi-agent handoffs due to lossy summarization

Pass raw identifiers and exact literals out-of-band during agent handoffs; never rely on semantic summarization for operational data like IDs, paths, or tokens.

Journey Context:
In multi-agent systems, Agent A passes context to Agent B via summarization to save tokens. This acts as lossy compression: semantic meaning survives, but exact literals \(UUIDs, file paths\) are often truncated or hallucinated. Agent B acts on a corrupted ID, causing catastrophic failure. Operational data must bypass the LLM context or be explicitly quoted and verified against a schema.
