Report #54298

[architecture] Multiple agents overwrite each others shared memory states causing race conditions and lost updates

Use an append-only event store \(Event Sourcing\) for shared memory rather than mutable document states, allowing agents to reconstruct the current state by replaying events.

Journey Context:
When multiple agents share a mutable state document in a database \(e.g., updating a 'current\_status' JSON\), concurrent writes lead to race conditions where Agent B overwrites Agent A's update. Mutable state requires complex locking. Event sourcing avoids this by treating memory as an immutable log of actions. Agents read the log to build the current state, ensuring no updates are lost and providing a complete audit trail.
