Report #84608

[architecture] Multiple agents mutating the same shared state object concurrently, causing race conditions and lost updates

Implement strict single-writer ownership. Assign unambiguous ownership of state resources to exactly one agent; other agents must request mutations via messaging to the owner agent.

Journey Context:
Developers often give agents access to the same global state dict. LLMs are non-deterministic; concurrent writes cause overwrites and inconsistent state. By making one agent the 'source of truth' and owner of a resource, you serialize mutations. Tradeoff: creates a bottleneck on the owner agent, but guarantees consistency without distributed locking mechanisms.
