A message can warn people about a conflict without preventing the conflict from damaging someone else’s work.

The practical check

Ask what must happen when two pieces of work collide: warn, pause, require a choice, or block the action until the conflict is resolved.

Where AI fits

AI can identify conflicting changes and explain the possible collision before work proceeds.

The human decision

People decide how to resolve the conflict; the system must enforce the stop where overwriting is possible.

The lesson

A conflict deserves an enforced halt when continuing could overwrite someone else’s work; a warning alone is not a safe substitute for the stop.

The Build Log companion walks through the actual conflict this post is drawn from, and the halt gate that replaced a warning that could not stop the overwrite.
