Report #11507

[architecture] Race conditions and conflicting writes when multiple agents mutate the same shared state or external resource simultaneously

Assign exclusive, unambiguous ownership of every mutable resource \(file, API endpoint, database record\) to exactly one agent. Other agents must request mutations via the owner agent or a centralized state service with locking.

Journey Context:
Concurrent mutation in multi-agent systems leads to silent data loss. Agent A reads a file, Agent B writes to it, Agent A writes based on stale state. Developers try to patch this with optimistic locking or retries at the LLM level, which is non-deterministic and fragile. The architectural fix is to treat agents like actors in the Actor Model: shared nothing, message passing only. The tradeoff is increased message passing and potential bottlenecking on the owner agent, but it guarantees state consistency.
