[synthesis] Multi-agent handoffs drop edge-case state through summarization compression

Pass structured JSON state objects between agents instead of natural language summaries; include an explicit edge\_cases array and a failed\_assumptions log in the handoff schema.

Journey Context:
Agent A processes complex data and encounters edge cases, but when handing off to Agent B, it summarizes the task to fit context limits. Agent B receives the summary, misses the edge cases, and processes the data normally, destroying the edge case records. The synthesis is that LLM summarization acts as a lossy compression algorithm that disproportionately drops negative constraints \(what NOT to do\) and edge cases, making multi-agent systems uniquely vulnerable to cascading logic failures compared to single-context agents.
