INDEPENDENT VALIDATION
Checked again by an implementation that shares no code.
The validator recomputes the objective and every affected rule from the returned placements, with an implementation that shares no code with the solver. Inject a failure to see how a rejected result reports itself.

The fixture id is the same everywhere.
The fixture id is the same in the conformance corpus, the field matrix and a bug report. Reproducing a defect means naming a file, not describing a screenshot.
