Report #101145

[architecture] Agent state diverges because each agent keeps a local copy updated asynchronously

Use a single source of truth with atomic state transitions and an append-only event log; reconstruct state by replaying events rather than broadcasting state diffs.

Journey Context:
Broadcasting mutable state snapshots is tempting but creates merge conflicts and ordering bugs. Event sourcing makes every change a first-class fact, gives auditability, and lets late-joining agents catch up. The cost is a more complex persistence model and the need for snapshotting to keep replays fast.
