Use limitations as information instead of verdicts.

A limitation treated as a verdict ends the inquiry. Treated as information, it tells you where the boundary currently is, why it is there, and what would move it, all of which is useful. The same fact functions completely differently depending on which way you take it.

Take a constraint you have accepted as final and ask what specifically imposes it. Sometimes it is genuinely fixed. Often it is a condition that could be changed by someone willing to ask.
