Report #37048

[architecture] Race conditions when multiple agents read/write the same shared state or file simultaneously

Assign unambiguous, exclusive resource ownership per agent. If shared state is absolutely necessary, implement optimistic concurrency control \(OCC\) using versioning/ETags, or use a centralized state server with atomic transactions.

Journey Context:
Developers often give agents access to a shared database or filesystem assuming sequential execution. In async multi-agent setups, Agent A reads a file, Agent B modifies it, then Agent A writes based on stale data. Prompting agents to 'be careful' doesn't work. You must enforce ACID-like constraints at the infrastructure level. Optimistic concurrency control fails gracefully by forcing the LLM to retry with fresh context, teaching it the state changed.
