> Of particular note is the “remux” community, dedicated to seamlessly stitching together the best video and audio streams from different releases without any generational loss of quality.
That’s not what “remux” means. A remux is the original data from, for instance, a Blu-ray disc, transferred into a new container without re-encoding. What the author is referring to would be called a “hybrid remux”.
Remux is not a community, it's a tag that pirate release groups uses to indicate that a release contains exact copies of the original video and audio streams present on the disc.
GP is correct that files with purely additive changes (like additional audio tracks) to remuxes are called hybrid remuxes.
ETA: To the author's credit, this is convention rather than a hard rule. I checked my usual sources and found the exact 89gb 4k Arrow remux the author mentions in the closing paragraph and it is indeed labelled 'remux' only. The uploader did make a note of this though: "Unfortunately, as Arrow had to pull the Italian dub due to rightsholders demands, I had to sync it from the 2017 Kino Lorber disc."

There is a community insofar as there is a relatively small group of people who sink their time into producing high quality remuxes, and this group talks to each other (on IRC and elsewhere).
>GP is correct that files with purely additive changes (like additional audio tracks) to remuxes are called hybrid remuxes.
As I corrected on a child comment to the GP, this is not correct. It is not convention either. A hybrid remux has a stream which is a hybrid of two or more sources. Simply combining tracks from different sources isn't a hybrid remux, it's just baseline good practice.
In my (admittedly limited) experience, adding audio tracks to a video track that weren't produced together often requires editing. If not for sample rate reasons, content reasons, like extra space for additional video space at the beginning or ending most basically. It seems like in any instances like that, which I would count as "nominal," it would be appropriate to identify those as "modified from" which would seemingly place you squarely into "hybrid" space within the taxonomy of this comment thread.
The muxer can apply a timestamp offset to a track, so while the audio stream remains untouched it starts at some offset relative to the start of the video stream.
Agree once you're compensating for drift by scaling the audio track you've pushed yourself out of remux territory, but again these aren't hard and fast rules (evidenced by the disagreement over terminology).
Right. There is some degree of transformation which is normal or necessary. For example, if one of {video, audio} is 24fps and the other is 23.976fps, the video will have its frame rate adjusted to match the audio. For basic video/audio mismatches you may need to trim audio, insert null audio, or add a mkv container delay.
These things are normally detailed in release notes. People write pretty detailed notes laying out exactly what they did.
