- validate the upstream requirement of exactly two commits
- accept soft reset followed by a replacement commit
- reject resetting to one commit without creating the squashed commit
- document squash validation parity
- create and enter the level's declared starting directory
- inspect Git state from the repository containing the active directory
- start the init level in /sandbox/git_hug and cover it with a runtime test
- apply edited reword subjects as commit messages in the in-app rebase editor
- cover rename_commit with a native interactive rebase regression test
- remove the upstream contribute call to action from the playable level catalog
- update level parity documentation
- Add LevelsCompare.md with setup and validation comparisons against Gazler/githug.
- Document that LevelsCompare.md must be updated when level behavior changes.
- Track FETCH_HEAD count in RepoState so the Fetch level can match upstream validation.
- Mirror upstream Status setup with staged files plus untracked database.yml.
- Keep Fetch from being solved by pull despite native Git FETCH_HEAD behavior.
- Bump app version and build debug APK.
