[synthesis] Receiving agent reverses prior agent decisions after handoff loses decision rationale

Structure handoff payloads to include an explicit decision log: for each significant choice, record what was chosen, what alternatives were rejected, and why. Receiving agents must parse the decision log before making new choices. Implement decision log as a typed data structure \(not narrative text\) so it can't be ignored or summarized away.

Journey Context:
OpenAI Swarm's handoff pattern transfers conversation history and current state, but the receiving agent optimizes for what appears locally optimal given visible state. Without understanding why previous agents made certain choices \(e.g., 'used library X instead of Y because Y has a known memory leak on ARM'\), the receiving agent may reverse those decisions. Each handoff compounds this: by the 3rd handoff, original design intent is completely lost. The common mistake is making handoff summaries more detailed, but detail without rationale is just more data to be skimmed. The synthesis: conversation history transfer ≠ knowledge transfer. A conversation contains what was said, not what was decided and why. Decision rationale is a different data type than conversational context, and treating them as the same thing is the root cause of handoff drift.
