Every massing option the V01 grid can produce on parcel Merdivenköy 3412/3 (Kadıköy, Istanbul), placed inside the real setback boundary and judged by zoning.py — KAKS, TAKS, Hmaks, buildable plates (max 22 m depth, so every block is a real residential slab), and daylight spacing at three levels: the legal floor, the committed 60° intent, and the 45° aspiration reported on every card. Gaps are measured on the drawn geometry. Sellable areas are estimated with factors calibrated from this parcel's own 2018 valuation report. Candidates that cannot physically fit the zone say so.
