Use this after the problem-space map and before solution search.
What map or context pack is this narrowing?
What visible bug, complaint, or friction could define the work?
What ownership boundary, data flow, invariant, or interface could define the work?
What behavior can someone not safely perform today?
Because [mechanism], [actor/system] cannot [needed behavior] without [risk/friction]. This run will address [slice/boundary]. If [evidence], the framing is wrong and we should revisit problem space.
What did we reject, and why?
In scope:
Out of scope:
What evidence would prove this framing wrong?
What should /solution-space compare?
