A comparison explains documented distinctions; it does not declare the compared parts electrically or functionally interchangeable.

Discovery is not a compatibility verdict.

These discovery surfaces route and reorganize facts already represented in the atlas. They do not add electrical ratings, universal pinouts, measured tolerances, exact-device support, wiring approval or an end-to-end compatibility result.
