System Build Notes.md (+ .rtf)	the 2025 build order for the boards (the .rtf is the original)
BUS Driver Commands - Google Docs.pdf	the bus-tester script language as sent by embedded/command-sender (LET/FOR/NEXT, labels, expected values, DUMP)

The PDF and the build notes were migrated 2026-09-19; MIGRATION.md at the repo root says which copy each item came from.
