+## Contributing
+### Local setup
+As a supply-chain hardening measure, this repository ships a project-level `.npmrc` that sets `ignore-scripts=true`. This blocks npm lifecycle scripts (`preinstall`, `install`, `postinstall`, `prepare`) from any direct or transitive dependency when you run `npm install` or `npm ci` inside the repo. See [THREATMODEL.md](./THREATMODEL.md) (threat T-S2) for the rationale.
+One consequence: the repository's own `prepare` hook (which installs Husky's git hooks) will **not** run automatically. After your first install, enable the git hooks manually:
+```bash
+npm ci
+npm rebuild husky && npx husky
+```
+Run those two commands once per fresh checkout. You do **not** need to re-run them after every subsequent `npm install`.
+Do not remove `ignore-scripts=true` from `.npmrc` to "fix" this — that re-opens the lifecycle-script attack surface for every other package in the tree. All CI workflows already invoke npm with `--ignore-scripts`, so local behaviour matches CI.
