 ## 7. NoteLett Backend Checks
 
+The automated local smoke entrypoint is:
+
+```bash
+pnpm run smoke:local
+```
+
+It follows the common-platform self-test convention of generating a short-lived local test JWT, then verifies:
+
+- `GET /health`
+- `GET /api/bootstrap`
+- platform-service, extraction-service, and mcp-server health
+- authenticated workspace create
+- authenticated note create/read
+- best-effort workspace/note cleanup
+
+Useful variants:
+
+```bash
+pnpm run smoke:local -- --no-start
+pnpm run smoke:local -- --skip-platform
+```
+
