Report #51136

[frontier] Agent handoffs between different implementations or languages serialize full state causing high latency and token costs

Use Differential State Synchronization \(DSS\): transmit only the delta \(diff\) of agent state changes during handoffs, using operational transformation or JSON Patch \(RFC 6902\) to merge state at the receiver

Journey Context:
Full state serialization includes the entire message history and context variables. For long conversations this is O\(n\) bandwidth and latency. DSS tracks state mutations \(new messages, variable updates\) since last sync and transmits only the patch. This is critical for high-frequency multi-agent coordination \(e.g., 10\+ agents passing tasks\) and for handoffs between edge devices and cloud agents where bandwidth is constrained. This replaces 'dump and restore' handoff patterns.
