     - If encountering a commit with conflicts that do not have a straightforward resolution, check if picking any prior commit would help resolve the conflicts.
       - Abort the rebase, update the authored `rebase-todo`, and restart the interactive rebase.
       - Avoid authoring manual changes unless absolutely necessary. If authoring changes, keep them as separate commits and indicate them as such on the authored rebase todo (insert either a `pick` instruction with the id of the commit you just authored or an `exec` instruction that makes the modifications and ends with `git commit -m $message`, in either case prefixing with an explanatory `##` comment).
-        - For `exec`, make portable in-place edits with either `ed` or `sed-i () { if sed --help 2>&1 | sed 2q | grep -qe '-i '; then sed -i '' "$@"; else sed -i "$@"; fi; }`, e.g. `printf 'H\n/\( *\)foo/ s##\\1// prettier-ignore\\\n&#\nw\n' | ed -s packages/path/to/file'` or `sed-i -E "$(printf 's#( *)foo#\\1// prettier-ignore\\\n&#')" packages/path/to/file`.

       - Linting locally can catch incompatibilities in the cherry-pick, often requiring some changes to be reverted or more commits from `master` to be included. In those cases, update the authored `rebase-todo`, and redo the interactive rebase as necessary.
