Undo safely

First ask Steve what he wants to undo. Then run git status and git log --oneline -10 to see where things stand, and explain it in plain words.

Pick the safe option:

• Changes to one file that are not saved yet (not committed): git restore <file>. This throws away those edits, so ask Steve first.
• The last save (commit) was bad: run git revert HEAD, then git push. This adds a new save that undoes the old one. Nothing is lost.
• An older save: find it with git log --oneline, then run git revert <id>.
• Settings only: change settings.toml back by hand.

Never use git reset --hard, git checkout -- ., git clean or a force push. They delete work for good.

Undo never touches data/ (the homes, statuses and notes), because git does not save it. To undo a home's status, run uv run python -m sellers mark <id> <status>.

After the undo, run uv run pytest and show Steve that things work again.
