Report #38850

[architecture] Concurrent file or database mutations by multiple agents causing race conditions and lost updates

Assign unambiguous singleton ownership per resource \(only one agent mutates a specific file/key\) or implement optimistic concurrency control \(OCC\) with enforced ETags/versioning.

Journey Context:
Distributed locking is brittle and prone to deadlocks in async agent workflows. While OCC handles conflicts gracefully, the most robust architectural choice for multi-agent systems is strict ownership—sharding the state space so only one agent has write access to a given entity, entirely avoiding distributed transactions and lock management.
