+## Signed Python launcher (macOS permissions)

+The manually built, signed **Reyna CLI.app** owns the macOS privacy identity. Use the `signed` wrapper to launch the current Python CLI through that app:
+
+```bash
+# Optional: use a different active checkout or interpreter without rebuilding the app.
+cat > ~/.reyna-cli.env <<'EOF'
+REYNA_CLI_DIR=/Users/adolforeyna/Projects/platform/reyna-cli
+REYNA_CLI_PYTHON=/Users/adolforeyna/Projects/platform/reyna-cli/.venv/bin/python
+EOF
+
+uv run reyna-cli signed doctor
+uv run reyna-cli signed local-services speech transcribe-file ./sample.wav --json
+```
+
+The signed launcher reads `~/.reyna-cli.env`, then `~/.config/reyna-cli/env`; `REYNA_CLI_DIR` and `REYNA_CLI_PYTHON` environment variables override those values. Python-only edits take effect on the next `signed` run—**do not rebuild or re-sign the app for those edits**. Changes to Swift sources, `Info.plist`, or app signing require a new manual signed Xcode build before they can be used by `signed`.
