Description

Context

From Vincent's review on PR #12 — interactive rebase (git rebase -i HEAD~N) can squash commits and lose commit history.

What to catch

  • git rebase -i / git rebase --interactive
  • Possibly also git commit --amend, git filter-branch, git reflog expire

Considerations

  • Interactive rebase is extremely common in normal dev workflows (squashing before merge). High false-positive risk.
  • Losing commit history is different from losing working code — severity should probably be medium + warn, not block.
  • May warrant its own category (destructive_git_history_rewrite) rather than adding to destructive_git_working_tree_loss.

Research direction

Start with the linked context in PR #12 and inspect how existing destructive Git rules are structured. Decide the scope for interactive rebase and the possibly related commands, then define the category, severity, and warning behavior; this is done when the rule's false-positive policy and test cases are agreed.
