Report #21604

[architecture] Multiple agents reading and writing to the same shared state object concurrently, causing lost updates and unpredictable behavior

Assign unambiguous, exclusive ownership of state resources to a single agent at any given time. If multiple agents need the same data, use an append-only event log or implement optimistic concurrency control \(e.g., ETags/versioning\).

Journey Context:
Distributed systems 101: shared mutable state is the root of endless bugs. In multi-agent LLM systems, if Agent A and Agent B update a shared JSON object simultaneously, one update overwrites the other. The Actor Model solves this by making state private to the actor. For LLMs, this means only the active agent 'owns' the write lock to a specific piece of state, or state transitions are modeled as immutable events rather than mutable CRUD operations.
