+- Never run git commands that create commits, push, or modify the index/history. The human owns these actions.
+- Forbidden commands include (non-exhaustive): `git commit`, `git push`, `git add`, `git rm`, `git restore --staged`, `git reset`, `git rebase`, `git merge`, `git cherry-pick`, `git stash`, `git commit --amend`, and `git tag`.
+- Read-only inspection is fine: `git status`, `git log`, `git diff`, `git show`, `git blame`.
+- When conflicts or staging are involved, resolve file contents in the working tree only, then hand off to the human to stage and commit. Describe the exact commands you would run instead of running them.

+Simulates a user performing the pull-to-refresh gesture on a host `ScrollView` element, invoking the `onRefresh` handler of its `refreshControl` prop.
+
+This function supports only host `ScrollView` elements, passing other element types will result in an error. Note that `FlatList` and `SectionList` are accepted as they render to a host `ScrollView` element.
+
+If the element has no `refreshControl` prop, or its `RefreshControl` has no `onRefresh` handler, the call resolves without doing anything.
