Compares declared finished plan square footage against the schematic gross envelope floor area (footprint x stories, garage excluded). This is the same gross envelope vs finished story as the measured-takeoff reconciliation: it is advisory and moves no money. Ratio 1x is below the seeded placeholder band but still physically possible; treat it as calibrated or more detailed plan dimensions, not a pricing disagreement.
Schematic-envelope quantities derived from the plan's box — advisory, not measured construction takeoffs.
