[architecture] Agents operating on stale global state after a peer modifies shared data

Implement an append-only shared event stream \(Event Sourcing\) rather than mutable shared state, allowing agents to reconstruct current state deterministically.

Journey Context:
If agents read and modify a shared mutable dictionary, race conditions and stale reads are inevitable. By using an append-only event log, every agent sees the linear history of actions. This guarantees that all agents can sync to the exact same state by replaying events, eliminating partial update anomalies.
