- Client IP: only trust X-Forwarded-For from RFC 1918 proxy IPs
- Webhook auth: handle nil/blank secret with controlled error, not 500 crash
- Sudo redirect: reuse validated return_path? from login to prevent open redirect
- Map live: remove redundant inline script (ensureLeaflet hook handles loading)
- Bang calls: convert crash-prone exact matches to case in QR live and API controllers
