How do I filter out git-log commits that are topologically irrelevant?

You can get close with --simplify-by-decoration, that will additionally list commits that have a tag on them. To cut unwanted chatter you can use one of my favorite tricks,

git clone -ns --no-tags . `mktemp -d`
git -C $_ log --graph --decorate --oneline --all --simplify-by-decoration

That clone will be tiny, for the linux repo it's 36KB.

This doesn't list the direct parents of every merge, it picks different parts of the ancestry to show the structure as compactly as possible without losing any of it, but it may be close enough to serve.

You can't find children of a commit starting from that commit, you have to walk back from all the tips you care about, so if a commit's not in any branch this won't find it.But then, if a commit's not in any history, it's not really going anywhere anyway, so...
