There was a problem hiding this comment.
I think this is a sound approach. I feel like this is also new enough that making these changes won't be very impactful to users.
One thing I realized while review this pull request is that we don't have a way to easily inspect test coverage. That's why I created #183.

Description
conda self reset --snapshot installer-exactcan fail when a recorded package URL disappears, even when the matching conda package remains installed.Exact resets now reuse installed packages whose URLs and recorded checksums match the snapshot. Conda prepares the remaining packages in a package cache, including
noarch: pythonpackages that need relinking after a Python version change. Local package archives are checked against recorded checksums. If preparation fails, reset reports the affected packages without exposing package URLs or credentials and leaves the target environment unchanged.The old
--snapshot installerspelling now stops before confirmation or environment changes and explains both replacements.installer-exactrestores the recorded packages.installer-updatedretains currently installed installer packages, conda plugins, and permanent packages with their dependencies, without updating or installing missing packages.Reset output respects
--jsonand--quiet.The broader CLI wording, documentation, and demo updates are in #181.
Closes #150
