Report #59016

[architecture] Race conditions and corrupted state from concurrent agents mutating the same resource

Assign exclusive, unambiguous ownership of every mutable resource \(file, DB row, state variable\) to exactly one agent; other agents must request mutations via message passing to the owner agent.

Journey Context:
In distributed LLM systems, agents operate asynchronously. If two agents read-modify-write the same shared state \(e.g., a shared scratchpad or code file\), last-write-wins destroys work. Developers often rely on 'being careful' or sequential prompting, but non-determinism in LLM routing breaks this. Enforcing strict single-ownership \(similar to the Actor Model\) eliminates distributed locks and race conditions. The tradeoff is increased message passing for shared resources, but it guarantees state integrity without requiring complex distributed locking mechanisms.
