[architecture] Agents keep inconsistent local snapshots because they poll each other's state at different times

Publish a single append-only event log; each agent rebuilds its own projection from events; use event IDs or vector clocks to detect causality.

Journey Context:
Polling another agent's state introduces race conditions: by the time you read, act, and write back, the world has changed. A shared event log becomes the single source of truth; agents derive local views by replaying events instead of copying state. This gives you eventual consistency with a clear audit trail. The common mistake is trying to keep every agent strongly consistent, which requires locks and blocks. Event sourcing fits the naturally asynchronous agent model. The tradeoff is storage growth and replay complexity, which are usually solvable with snapshots.
