Report #48752

[architecture] Agents operating on stale state because shared memory updates are asynchronous or eventually consistent

Use an append-only shared blackboard or event stream \(Event Sourcing\) with a strict schema, rather than allowing agents to mutate a shared global state object directly.

Journey Context:
Multi-agent systems often use a shared dictionary or database to synchronize state. When agents read and write concurrently, they can read stale data or overwrite each other's changes. Event sourcing \(appending state changes as immutable events\) allows agents to reconstruct the latest state deterministically. It also provides a perfect audit trail for debugging agent coordination failures. The tradeoff is increased complexity in state reconstruction, but it guarantees consistency and eliminates race conditions on the read/write path.
