Click the card. The same citation drawer the scanner surfaces opens against a pre-canned IL scenario — federal IRC §280A + IRS Form 8829 stack, plus the 35 ILCS 5/203 and 5/201 state mirror citations the scanner carries on the same cell. Read the authority trail, then start a free trial to run the lens against your own IL engagement queue.
Pin-cites included
Federal §280A simplified method (300 sq ft cap at $5/sq ft) plus state-side add-back conformity. The drawer surfaces the federal IRC + Form 8829 stack and every per-state mirror pulled from STATE_CITATION_REGISTRY for this cell.
