Report #3103

[architecture] Agents see inconsistent snapshots of shared state and replay is impossible

Synchronize through an append-only event log; each agent derives its local view from events and writes new events back, never mutating another agent's state directly.

Journey Context:
Broadcasting mutable state copies leaves agents with stale or conflicting views. An event log gives a single source of truth, supports replay for debugging, and makes every state change auditable. The tradeoff is higher storage and schema evolution as event shapes change. Never share live object references across process boundaries.
