A placed sheet is the library's published sheet byte for byte, or the board's copy under its own designators, which is compared with the brief in pure text: the parts by internal part and count, the ports by name and shape. The netlist check is the brief check run on the sheet with kicad-cli (--brief-check), recorded in brief-checks.json beside these pages.
