 ## CI
 
-- **On each pull request to `main`:** CI sets up mise 2026.10.19 and the locked tools with [mise-action](https://github.com/jdx/mise-action), then runs `pnpm install --frozen-lockfile`, `pnpm rr check`, `pnpm test` and `pnpm build`, once on the Node floor in `mise.floor.toml` and once on the version in `mise.toml`. Beside them, gitleaks scans the pull request's commits for secrets. The required `Test` check passes when all three do. Adding a label runs CI again, and labels added at once don't cancel one another's runs. Of those runs, only one that adds `preview` to a branch other than `feat/*` or `fix/*` publishes a preview. Workflow audit runs [zizmor](https://docs.zizmor.sh) on every workflow in the repo, including those the vland templates generate.

Of those runs, only one that adds `preview` to a branch other than `feat/*` or `fix/*` publishes a preview, and a pull request opened on such a branch with `preview` publishes from its label run, not its `opened` run.

 - **Git hooks** ([lefthook](https://lefthook.dev)): `lefthook.yml` extends the two configs that `@rrlab/cli` ships, `run-run/cli/lefthook/base.yml` and `run-run/cli/lefthook/turborepo.yml`, and its own `shared-hooks` job fails a commit, saying to run `pnpm install`, when they are missing from `node_modules`. Their jobs are listed in [the cli's README](../run-run/cli/README.md#git-hooks). `lefthook/turborepo.yml` is not dx's: it holds the hooks that other repos fetch remotely.
 - **Every Monday:** `pnpm audit` on the lockfile, which keeps an issue labeled `dependency-audit` open while it finds known vulnerabilities (Dependency audit).
