-### Improve signature handling in fast-export/fast-import and git-filter-repo
-
-Git's `fast-export` and `fast-import` commands are powerful tools for
-repository manipulation and migration, and `git-filter-repo` builds on
-these to provide advanced repository filtering capabilities. However,
-handling of commit and tag signatures during these operations could
-be significantly improved.
-
-Currently, signatures may be lost or become invalid when objects are
-exported and imported, which can be problematic for repositories that
-rely on signed commits or tags for security and verification purposes.
-
-This project aims to improve how these tools handle signatures by:
-- Preserving signature information during export/import operations
-- Providing options for signature handling (preserve, strip, re-sign, etc.)
-- Ensuring signature validity is maintained or appropriately flagged
-- Extending `git-filter-repo` to handle signatures correctly
-- Adding tests and documentation for signature-related workflows
-
-**Note:** This project may potentially conflict with ongoing work by GitLab
-developers (including Christian Couder) on signature handling. Applicants
-should coordinate with mentors before proposing this project to ensure the
-work would not duplicate ongoing efforts.
-
-**Getting started:** Build Git from source, experiment with `git fast-export`
-and `git fast-import` on repositories with signed commits and tags, study
-the current signature handling code, review `git-filter-repo` functionality,
-understand GPG signature verification in Git, and submit a micro-patch to
-demonstrate familiarity with the codebase.
