Report #39088

[architecture] Agents operating on stale state due to polling delays or async update failures

Use an append-only event log \(Event Sourcing\) for shared state mutations. Agents subscribe to the event stream to maintain their local state, rather than querying a central DB that might return stale data or cause race conditions on updates.

Journey Context:
In a multi-agent setup, if Agent A updates a shared database and Agent B queries it later, B might read stale cached data or suffer from eventual consistency delays. By using an event stream, every state change is broadcast as an immutable event. Agents maintain their own materialized views. This decouples the agents, guarantees causal ordering of events, and makes debugging coordination failures trivial \(you can replay the event log to see exactly what each agent saw\).
