Whole neutral source

Fictional paper scene: First costume-label scene. There are 4 columns A to D, left to right, and 4 rows 1 to 4, top to bottom. All cells have the same size. Up/down mean towards the top/bottom of this page; left/right across this page. One move reaches one neighbouring cell, never a diagonal. Start: B2. Target: D3. The name-card is at A1; the spare-card is at D4. Closed cells: C2. Do not enter or pass through them. Proposed instruction: 2 cells right, then 1 cell down. A supplied helper says: “Reaching D3 would make the whole proposed route legal.” This is a supplied scene. Read its whole legend before the questions; it is not a real place, a measured route or an observed journey.
