For each prototype, climate zone and vintage, the robust zoning is the coarsest (fewest modelled zones) that meets the threshold at every orientation of the cell pair, by the writer's own verdict on each zoning at each orientation, with at most the reference's zone count, as the writer bounds a recommendation (D-220); a duplicate never meets, as the writer lists it. Ties at the fewest zones go to a zoning both orientations recommend, else to the first in the study's zoning order (simplifier, join pieces, perimeter depth, stacker, IWHT, FHT); the tied zonings are named. The errors reported are the worse of the orientations' values for each metric, so the row is a bound, not a mean; the cost ratios are the medians over the timed sites of that zoning in the pair. Where both orientations recommend the same zoning it is the robust one. A pair where no zoning meets the threshold at both orientations says so and names each orientation's own recommendation; the per-orientation rows below stay the reading for one orientation. The cost ratios are the median over the timed sites of the robust zoning in the pair (in this drop one orientation at most is timed, so the ratio is that site's); not timed where none is. The rule and its limits.

The coarsest zonings (fewest modelled zones) meeting the threshold; ties are all listed. Errors are the test zoning against the reference: annual sensible load, hourly CV(RMSE) and NMBE, and the change of conditioned floor area. A muted value belongs to a load the threshold does not judge; a dash is a value the runner did not store; a flagged value carries the runner's own flag. The cost ratios are the serial timing pass (R5): the zoning's processor time, wall clock and peak committed memory over its reference's, each the median of its repeats; not timed marks a cell outside the timed ones. Cost protocol.
