[architecture] Divergent agent states causing conflicting actions based on stale global information

Use a centralized, append-only state store \(Blackboard architecture\) that agents read from and append to, rather than maintaining independent mutable states that require two-way synchronization.

Journey Context:
Treating agents like microservices with independent databases leads to merge conflicts and stale reads. The Blackboard pattern solves this: agents are stateless workers that read the current world state from a central hub, perform their task, and write updates back. It trades off agent autonomy for guaranteed global consistency. This is critical in coding tasks where file states and task progress must be exact, avoiding the complexity of distributed state synchronization.
