+  - `npm run check-packages [-- <package>...]` (the `Package` CI job) enforces this: it builds each package from a clean `build` directory, packs it, fails if the tarball contains test-only files, and runs `publint` and `@arethetypeswrong/cli` against the tarball.
+  - `npm run check-compiles` emits tests into the same `build` directories, so do not `npm pack` from a working tree after running it.
 - For substantial changes to GitHub Actions, runner images, Node/npm versions, or release/publish automation, consider running the manual `Node.js Package` workflow as a dry-run publish sanity check.

    - When working in a fresh git worktree, dependencies are not installed (`node_modules` is absent), so verification commands (tests, `lint`, `format`, `check-compiles`) will fail with "Cannot find module" errors. Run `npm ci` once before verifying. `npm ci` only populates `node_modules` and must not modify `package-lock.json`; if it does, treat that as drift to investigate.
 5. Verify git diff only contains intended files.
 6. Never commit, push, or post on GitHub (issues, PRs, or comments) without first sharing the proposed diff/message and getting explicit user approval.
