[architecture] Context drift where Agent A assumes X and Agent B assumes Y based on isolated, stale memory

Use a centralized shared state store \(a global scratchpad or graph state\) that agents read from and append to, rather than passing full conversation history via messages.

Journey Context:
Passing full conversation history between agents is token-expensive and leads to drift if not perfectly merged. A central state \(Blackboard architecture\) allows agents to read only the specific keys they need for their current task. Tradeoff: Centralized state becomes a bottleneck if not partitioned well, but it ensures all agents operate on the same ground truth.
