[architecture] Agents operate on stale state because shared mutable state was updated by one agent but not propagated to others before they acted

Replace shared mutable state with an append-only event log \(Event Sourcing\). Agents subscribe to the log and maintain their own local materialized views, ensuring causal consistency.

Journey Context:
A common anti-pattern is a shared database that agents poll. Polling introduces latency, leading to agents acting on stale data. Event sourcing ensures that once an agent processes an event, its local state is consistent with the sequence of truths. The tradeoff is eventual consistency and the complexity of rebuilding state from events, but it prevents the 'lost update' and 'stale read' problems inherent in multi-agent concurrent execution.
