Report #5070

[architecture] Agents operating on stale or divergent world state because context is passed by value rather than by reference

Use a centralized, append-only state store \(blackboard architecture\) that all agents read from and append to, rather than passing full state copies in messages.

Journey Context:
Passing the entire conversation history or state between agents bloats context windows and creates race conditions if Agent A acts on state that Agent B just changed. A shared blackboard allows agents to pull only the relevant state deltas they need. The tradeoff is introducing a central bottleneck, but it ensures all agents operate on the ground truth of the current state.
