Report #45292

[architecture] Concurrent state modification causes race conditions and lost updates between agents

Implement unambiguous resource ownership \(single-writer principle\) for shared state keys, or use optimistic concurrency control with ETags.

Journey Context:
Developers often treat agent state as a globally shared mutable object. When multiple agents run asynchronously, they overwrite each other's changes. Alternatives like distributed locking often cause deadlocks in LLM loops because agent reasoning times are highly variable. The right call is assigning strict ownership of state keys to specific agents \(e.g., only the DB Agent writes to db\_state\) or using append-only logs with ETags for shared resources.
