Report #50483

[synthesis] Multi-agent handoffs cause data mutation via implicit format assumptions

Enforce strict, versioned interface contracts \(like Protobuf or JSON Schema\) between agents, explicitly declaring formats \(e.g., RFC 3339 for dates\) rather than relying on implicit handoff strings.

Journey Context:
In multi-agent systems, Agent A extracts a date as '01/02/2023' \(Jan 2\), Agent B assumes DD/MM/YYYY \(Feb 1\), and Agent C writes it to the database. No single agent owns the full pipeline context. Treating agent handoffs as internal function calls rather than distributed system APIs causes 'telephone game' data corruption. The fix requires applying distributed systems contract principles to LLM orchestration, revealing that agents need stricter API boundaries than human teams.
