[synthesis] Multi-agent system enters infinite wait states or loops without throwing exceptions

Implement a global state hash or vector clock at the orchestration layer. Alert if the state hash cycles \(loop\) or if an agent's write operation results in no semantic change to the global state \(deadlock/stall\).

Journey Context:
In multi-agent frameworks, agents pass messages and update a shared state. A silent degradation occurs when an agent misinterprets the state and overwrites it with the exact same or slightly regressed state. No error is thrown because the state schema is valid. The orchestrator just passes it to the next agent, who does the same. The system runs up massive compute bills looping silently until a timeout hits, which is often misdiagnosed as a performance issue rather than a logical deadlock.
