Report #11688

[architecture] Assuming all agents need access to a global, mutable scratchpad leading to state corruption

Default to isolated, agent-scoped memory. Use a central read-only knowledge base for shared facts, and an event bus or message broker for state mutations.

Journey Context:
A global scratchpad seems like an easy way to share state, but it leads to race conditions and agents overwriting each other's data. If Agent A writes a plan and Agent B modifies it, Agent A's subsequent actions might be invalid. Isolating memory forces agents to communicate through well-defined interfaces \(messages\), making the system deterministic and debuggable, adhering to the shared-nothing architecture principle.
