Report #99773

[architecture] Two agents overwrite each other's file edits because ownership boundaries were implicit

Assign each agent a unique filesystem subtree or file scope; never let two agents hold write access to the same path simultaneously. Serialize writes through a coordinator or atomic checkin.

Journey Context:
Concurrency feels efficient until both agents rewrite the same module and one branch silently vanishes. Shared scratch directories are the most common trap. Lock-free designs work only for read-only caches; any writable resource needs a single owner at a time.
