Report #24707

[architecture] Synchronizing full conversation histories between agents causing context window bloat and exponential token cost

Synchronize only structured summaries or delta-states \(differences\) between agents, not raw message histories.

Journey Context:
Naively passing the entire chat history seems like the safest way to preserve context, but it hits token limits quickly and dilutes the signal with irrelevant conversational turns. Summaries/deltas keep the context lean. Tradeoff: risk of losing minor details vs. maintaining operational capacity and reducing cost.
