# Get onto the working branch All work happens on a prefixed feature branch — never on a protected branch (`main`/`master`/`release/*`). The safety hook blocks pushes to protected branches. **Two paths — know which one you're in:** - **In the factory (the normal case):** the runner has ALREADY created your `gaffer/…` branch and checked you out onto its worktree. You do **not** create or switch branches — you **verify** you're on the right kind of branch and stop if you aren't. See *Factory path* below. - **Standalone / non-factory:** no branch was prepared for you, so you create one yourself with the exact convention. See *Standalone path* below. ## Factory path — VERIFY, do not create The runner already created and checked you out onto your `gaffer/ticket-<number>-…` worktree branch. Your job is to confirm the ground is safe, not to branch: 1. **Confirm you're on a non-protected branch.** Check the current branch (`git branch --show-current` / `git rev-parse --abbrev-ref HEAD`). It must NOT be `main`/`master`/`release/*`. The `gaffer/` prefix is expected. 2. **Do NOT run `git switch -c` / `git checkout -b`.** A branch already exists; creating another one diverges from the worktree the runner set up and the factory expects. 3. **Check the working tree is clean.** Run `git status --porcelain`. If it is dirty — uncommitted or untracked state left over from a prior partial run on this worktree — do **not** branch over it or start editing on top of it
