One owner per artifact — even when the workers are software

Two AI employees overwrote each other twice in one night. The models were fine. The ownership model was not.

Rule: One owner per artifact — even when the workers are software.

What happened

Two agents, both competent, both scheduled, both writing “the same” work product into the same place. First write looked complete. Second write believed it owned the file. Morning review: missing sections, mixed voice, a night of labor collapsed into conflict.

The instinct is to blame the models. The fix is not a smarter model. The fix is the same rule human teams already know: one owner per artifact.

Why AI makes this worse

Humans hesitate before overwriting a colleague’s document. Agents do not feel social friction. They execute. Parallel agents without ownership rules are a race condition with a keyboard.
