Where do you decide whether separated stems are worth keeping?

I have an audio-production workflow question about where people make the accept/reject decision for separated stems.

When a mixed track is split into vocal and instrumental parts outside the DAW, the files are not automatically useful just because they exist. A vocal stem can have backing-track bleed, an instrumental can still contain vocal remnants, and dense sections can reveal artifacts that are not obvious in an intro.

The workflow I am thinking about is:

1. Keep the original mix as a reference.
2. Separate one rights-cleared local file at a time.
3. Preview the vocal and instrumental results before saving them.
4. Import only if the result is good enough for the production goal.
5. Check the stem again in the DAW with level matching, muting, and context from the actual project.

For production work, do you usually trust the tool preview for the first decision, or do you only decide after importing the stems into your DAW?

My bias is that browser preview is good for rejecting obvious failures, but the real decision happens in the session. The stem has to sit against the arrangement, metering, editing goal, and maybe other processing before it is worth keeping. https://ai-vocal-remover.com

I am especially curious how people handle temporary stems: separate folder tracks, color coding, printed scratch tracks, or immediate deletion if the result is not good enough.

Disclosure: I work on a small browser audio-separation workflow, but I am intentionally not linking it here.
