[architecture] Agents operating on stale world state because shared memory updates are asynchronous or eventually consistent

Use a centralized, immutable event log \(append-only\) as the source of truth; agents derive their state by replaying events or querying a materialized view atomically before acting, rather than relying on cached local state.

Journey Context:
In multi-agent setups, if Agent A updates a database and Agent B reads it a millisecond later, eventual consistency might mean B reads stale data, leading to conflicting actions \(e.g., double booking\). Caching state locally in each agent exacerbates this. Event sourcing ensures all agents see the same linearizable sequence of truth, and reading from the materialized view guarantees up-to-date state at the cost of slightly higher read latency.
