[architecture] Agents hallucinating shared global state that doesn't exist or is out of date

Maintain an append-only shared ledger for global facts, but rely on local agent context for transient reasoning. Agents must explicitly read from the ledger before acting on global facts.

Journey Context:
Agents often assume their local view of the world is the global truth. If Agent A updates a database, Agent B might still act on its stale context. An append-only shared ledger \(like an event stream\) provides a single source of truth. Agents must query this ledger to ground their reasoning, preventing actions based on outdated assumptions.
