Updated and independently verified all 30 terminal names and descriptions; numeric pin-to-pad mapping remains exactly 1:1, including both GND pins. The project description is corrected.
Open platform limitation: root MPN remains ABX00142_Arduino_Nano_R4_NUMERIC and package remains TO; attempted edits did not persist. I filed an internal platform report for these two blocked metadata fields.
