FIXTURE / regression-support-ratio
Minimum support ratio
Support measured against the exact supporting footprint area, so a box that merely fits above a gap is rejected rather than reported as packed.

What it pins down.
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.
