Hi,

this patch series fixes some small issues I've discovered while working
on some other patch series. I've decided to split it out of these
because I'm hitting the same issues in multiple series, and I don't want
those to become dependent on one another.

The patch series is built on top of f0ef5b6d9b with
ps/object-source-management at ac65c70663 (odb: handle recreation of
quarantine directories, 2025-11-19) merged into it.

Changes in v2:
  - Drop the first commit that regards geometric repacking with promisor
    remotes. As it turns out my assertion was wrong: geometric repacks
    do and have to consider promisors, but they will fail to handle
    them. This is a bigger topic to fix though, so I'll rather want to
    move this into a separate patch series.
  - Tighten tests a bit for the commit-graph generation.
  - Stop referring to a "subsequent" commit that doesn't exist.
  - Link to v1: https://lore.kernel.org/r/20251205-odb-related-fixes-v1-0-ef4250abb584@pks.im (local)

Thanks!

Patrick
