+### Build troubleshooting (Linux OpenSSL errors)

+If you see an `openssl-sys` build error, sync dependencies and rebuild with the repository lockfile:
+
+```bash
+git pull
+cargo build --release --locked
+cargo install --path . --force --locked
+```

+ZeroClaw is configured to use `rustls` for HTTP/TLS dependencies; `--locked` keeps the transitive graph deterministic on fresh environments.
