Exact rules for the creation and use of sidecar files

Yes correct, i ment no data other then exif and edit data stored in the dopfile.

i did feel free to enhance, add your findings

i found out a quirk:

[type] in bridge is not a keyword it’s a drawer (header) with keywords inside. so i never should see “type” visual in the jpg properties as “keyword” but it does.
that’s in my eye’s a mismatch/bug.
