+## Security Rules
+
+- Do not commit secrets, tokens, `.env` files, certificates, or private keys.
+- Treat generated credentials as sensitive.
+- Prefer local generation and local processing for user data.
+- Keep dependency audit results visible in CI once dependencies exist.
+- Do not add external network calls unless the feature explicitly requires them.
+- Document any external assets, API calls, telemetry, or package publishing behavior when implementation begins.
+
+## Release Rules
+
+No published release process exists yet.
+
+Before a release:
+
+1. run `npm run build`,
+2. run `npm test`,
+3. run the release checklist,
+4. verify CI is green,
+5. verify download links when publishing artifacts,
+6. update README and changelog,
+7. create a tag,
+8. create the release.
+
+Do not create releases unless the user explicitly asks for a release.
