[synthesis] Multi-agent handoffs lose the 'why' behind decisions, causing locally optimal but globally catastrophic choices

Augment every inter-agent handoff payload with a structured 'decision log': a minimal list of \(decision, rationale, constraint\) triples that the receiving agent must acknowledge before acting. Implement this as a typed field in the handoff schema, not as free-text in conversation history. The receiving agent's first action must be to restate the active constraints from the decision log before proceeding.

Journey Context:
OpenAI Swarm's handoff mechanism transfers conversation history and context variables. AutoGen passes message sequences. Both preserve the 'what' \(results, code, data\) but lose the 'why' \(why this approach was chosen, what alternatives were rejected, what constraints governed the choice\). The receiving agent sees the output of the previous agent's work but not the decision tree that produced it. This creates a 'telephone game' compounding effect: Agent A chooses approach X because of constraint C, Agent B receives X's output, doesn't see C, and makes a choice that violates C because it optimizes for a different objective. Each handoff strips another layer of reasoning context. The fix is not 'pass more context' \(which worsens context window pressure\) but 'pass structured decision metadata' that is compact, typed, and mandatory to acknowledge.
