Report #9390

[architecture] Multiple agents editing the same file concurrently causes race conditions and lost writes

Assign unambiguous, exclusive resource ownership per agent, or implement distributed locking \(e.g., flock or Redis lock\) before any file mutation. If Agent B needs a file owned by Agent A, B must send a structured request to A.

Journey Context:
When multiple agents operate on a shared filesystem, they often read a file, compute changes, and write back. If Agent A and B read simultaneously, the last to write overwrites the other's changes \(the classic 'lost update' problem\). Alternatives include operational transformation \(too complex for code\) or merging \(LLMs are notoriously bad at blind merges\). The right call is strict ownership: Agent A 'owns' auth.py. This sacrifices parallelism on shared files but guarantees consistency, mirroring the Actor Model of concurrency.
