Field notes
The stair workbench exposes controls for floor-to-floor rise, tread run, stair width, mounting style, tread thickness, and riser count; its sample output includes a 35.3° slope, 7-7/16-inch rise, and an IRC pass. Separate tools describe 4×8 sheet optimization with grain lock and 1/8-inch kerf, tile-grid planning with sliver detection, and board-and-batten marks. The page also lists 60 presets and 46 field manuals, though their contents are not shown in the extracted evidence.
