+The third verified project, `sha256-4d63253294dcf0239d17`, contains three
+`CutSetting` elements in order: Cut (80000, 180), Scan (1000000, 10), and
+Cut (80000, 180), expressed as raw (frequency, pulse width) pairs.
+
+Reinspection of all three projects also identifies `CutSetting_Img` in both

+`ditherMode="3dslice"`, and no `QPulseWidth` child. The third project includes
+Bitmap, Ellipse and Path shapes. These image settings require a separate parser
+path from ordinary `CutSetting`; observing the stored mode does not establish
+Rayforge support for equivalent image processing.
+
+All five Scan settings also have `crossHatch Value="1"`. These are stored
 layer settings, not independent proof of which settings emitted on a machine.
 Successful operation is the operator's statement; it was not replayed here.
