[architecture] Agents operating on stale context because state updates were buried in conversational history instead of shared memory

Use a shared scratchpad \(blackboard architecture\) for mutable global state, keeping inter-agent messages strictly for task routing and intent, not state synchronization.

Journey Context:
Developers often try to synchronize state by having agents announce changes in chat. The receiving agent might summarize or drop this from its context window, leading to stale reads. The Blackboard pattern decouples state from conversation. Agents read from the blackboard before acting. The tradeoff is that the blackboard becomes a single point of failure and requires schema enforcement, but it guarantees all agents read the latest ground truth without relying on LLM memory retention.
