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.
