[architecture] Agents operating on stale state because broadcasting full state updates to all agents is too expensive or slow

Use a centralized Blackboard architecture where state is stored in a shared, structured repository, and agents query or subscribe only to the specific state slices they need.

Journey Context:
Keeping multiple agents synchronized typically involves either broadcasting every state change \(causing context bloat and token waste\) or letting agents drift out of sync. The Blackboard pattern solves this by decoupling the agents from each other. Agents read from and write to specific keys in the blackboard. This ensures a single source of truth, prevents context window pollution with irrelevant state changes, and allows agents to operate asynchronously without needing to know about each other.
