Report #88397

[architecture] Two agents modifying the same file or state simultaneously causing lost updates

Implement strict, unambiguous resource ownership \(e.g., one agent owns a file/workspace\) or use an actor model where state is mutated via message passing, not shared memory.

Journey Context:
Shared mutable state is the root of all evil in distributed systems, and LLM agents are no exception. Agents taking turns writing to the same file without locks leads to overwrites. The Actor Model ensures only one agent mutates a resource at a time. If multiple agents need the resource, route the task to the owner rather than sharing the resource.
