[synthesis] Multi-agent handoffs cause state mutation via summary loss

Pass full object references or deterministic IDs during handoffs, not natural language summaries. The receiving agent must fetch the current state directly from the source of truth, not trust the summary payload.

Journey Context:
When Agent A hands off to Agent B, it typically summarizes the state to save tokens. Agent B treats this summary as the complete state and makes destructive actions \(e.g., deleting database rows not mentioned in the summary\). This mirrors the saga pattern in microservices but without the transactional integrity. Passing full state is too expensive; passing summaries is lossy. The synthesis is to pass pointers \(IDs\) and force the receiver to query the source of truth, trading a few extra tool calls for data integrity.
