The tree within a git-series commit includes a blob "cover" for the cover letter, a gitlink "base" for the base commit, and a gitlink "series" for the top of the series. I could add a gitlink "notes", which acts like a notes ref; then, each version of the series would have its own notes ref. As with the series, git-series would track the "history of history"; since git-notes themselves use git history to store a set of notes, git-series would store the history of the notes. So if you add, remove, or change a note, git-series would track that as a change to the notes ref. If you merge/rebase/etc the notes ref to merge notes, git-series would track that too. A different series would have a different set of notes, so you wouldn't be limited to one notes ref per repository. This doesn't solve the problem of merging notes, but it *does* mean you have a full history of the changes to notes, not just the notes themselves.

I was mostly joking there. Rust makes that potentially reasonable, unlike most languages that can consume but not easily provide a C API, but that doesn't make it the ideal solution quite yet. :) > And ofcourse in C we have native access to libgit2.
