[architecture] Agents operating on stale context because shared state updates are not propagated or synchronized

Use an append-only event stream \(Event Sourcing\) or a centralized blackboard architecture for shared state, rather than passing mutable state dictionaries between agents.

Journey Context:
Passing a mutable 'state' object between agents means an agent only sees the state as it was at the moment of handoff. If Agent A and Agent C both need Agent B's output, A must wait for B, then pass to C. A blackboard or event stream allows agents to publish events and read the latest global state concurrently without tight temporal coupling. The tradeoff is the overhead of maintaining the event store, but it solves the stale read problem entirely.
