# Branch Hygiene The user has a three-layer auto-hygiene system in `~/dev/dotfiles/`: ## What's already automatic 1. **GitHub-side settings** (set via `gh-bootstrap.sh`): every repo has `delete_branch_on_merge=true`, `allow_auto_merge=true` (Git Pro), `allow_update_branch=true`, and a squash-only merge policy with `squash_merge_commit_title=PR_TITLE` / `squash_merge_commit_message=PR_BODY`. 2. **Daily systemd timer** (`git-hygiene.timer`, fires 09:30 local) — runs `gh-bootstrap.sh --check --all ~/dev` and writes drift state to `~/.local/state/hygiene/status.json`. On Sundays it also runs `git-hygiene.sh clean ~/dev --yes` to delete locally-merged branches. 3. **Shell `gh` wrapper** in `.bash_aliases` — when the user runs `gh repo create` or `gh repo clone` from their shell, the wrapper auto-runs `gh-bootstrap.sh` on the new repo. Note: this only fires from the user's interactive shell, not from agent-spawned shells. ## Workflow When the user asks about hygiene state: 1. Read `~/.local/state/hygiene/status.json` first — it's the cached daily check. Use `~/dev/dotfiles/hygiene-status.sh --status` for a one-liner or `--text` for a full readout. This is read-only and instant. 2. If the user wants a fresh check, run `~/dev/dotfiles/gh-bootstrap.sh --check --all ~/dev`. 3. To clean stale local branches now (instead of waiting for Sunday): `~/dev/dotfiles/git-hygiene.sh clean ~/dev --yes`. 4. To bootstrap a new or drifted repo: `~/dev/
