Also fix test portability: use 'git checkout -' instead of hardcoded 'main' branch name for cross-platform compatibility.

The orphan branch layer has the same retry behavior as the orphan backend. + +### Does the `squad-state` branch show up in my PRs? + +No. The `squad-state` branch is an **orphan branch** — it has no common ancestor with your main branch.

Other team members won't see your latest decisions or agent histories until you push. This is no different from forgetting to push any other branch — Git is distributed, and state only syncs when you push/fetch. + +### Can the `squad-state` branch be deleted safely? + +**No.** Deleting it loses all permanent squad state (decisions, agent histories, logs). Treat it like your main branch — push it to the remote and don't delete it. You can recover from a local deletion by re-fetching from the remote: `git fetch origin squad-state:squad-state`.
