[synthesis] multi-agent handoff context loss: decision rationale missing at transfer point

At every handoff point transmit not just current state but decision rationale: what was chosen, what was rejected and why, and what constraints must be honored. Structure handoff payloads to include explicit 'constraints' and 'anti-goals' sections. The receiving agent must acknowledge these before acting.

Journey Context:
Multi-agent handoffs are lossy compression. Agent A knows it chose REST over GraphQL because of a specific latency requirement but only passes the current code state to Agent B. Agent B sees the REST implementation, decides GraphQL would be cleaner, and rewrites everything — undoing hours of work and breaking the latency contract. The information lost is not the code but the why. Standard handoff mechanisms transfer context as conversation but conversation is lossy — the receiving agent skims, prioritizes recent messages, and misses buried constraints. OpenAI Swarm's handoff pattern transfers context via function calls but the burden is on the developer to structure what gets passed. The fix is structured handoff payloads that make constraints and anti-goals explicit and prominent, not buried in conversation history. The tradeoff is verbosity — more structured handoff data means more tokens — but losing a constraint is far more expensive than the tokens saved by omitting it.
