Report #27440

[architecture] Two agents updating the same shared state simultaneously causing race conditions or lost updates

Implement unambiguous resource ownership \(single writer principle\) where only one designated agent mutates a specific part of the state, or use optimistic concurrency control with versioning.

Journey Context:
In distributed systems, concurrent writes corrupt state. Agents are no different. If Agent 1 and Agent 2 both read a shared task list and append to it without locking, one update overwrites the other. Assigning strict ownership \(only Agent X mutates Resource Y\) or using ETags/version numbers prevents this, ensuring state integrity across parallel executions.
