The SVG is editable vector source; PNG is its raster rendering. The circuit contract contains exact physical pin and pad requirements. Observations CSV is deliberately blank. Native EasyEDA/OSHWLab project identity, ERC/DRC, assembly, thermal qualification and physical results require separate evidence; this ZIP proves none of them. Do not order a board from this author package.
