ETHERNET SPLIT PAIR WIRE MAP
----------------------------
Python 3.9+, standard library only. Extract all files into one directory.

  python3 wire_map.py --kind synthetic synthetic-control.csv
  python3 wire_map.py --kind synthetic synthetic-split.csv
  python3 test_actual_program.py -v

The two synthetic files have identical DC identity maps. Their physical
color observations differ. Use a copy of observations-blank.csv to record
your own results on one disconnected, unspliced specimen, then run:

  python3 wire_map.py --kind observed my-readings.csv

Use connector contact identities verified on both passive adapters. Enter
each pin 1–8 once. Enter every remote match, joined by |, or - if no link
was found. A blank means unfinished. End colors are WO/O, WG/G, WBL/BL,
WBR/BR or ? for unknown. One row's color cells refer to the same numbered
contact at each end, independent of the remote links.

Threshold, meter readings, source and hookup are documented in the article.
Leave both specimens unplugged from all powered or installed wiring.
The synthetic results and code tests are host evidence only.
