To capture the actual client IP for audit purposes, the frontend must inject a trusted internal header (e.g. `X-Real-IP`) from its own `r.RemoteAddr` before proxying. The backend reads `X-Real-IP` if present and falls back to `request.client.host` otherwise. This header is only trusted when it originates from the frontend proxy (not from an external caller), so the backend must not accept it from requests that bypass the frontend (direct API calls using the `X-Label-Hub-Key` header are expected to be forwarded through the proxy too in the standard HomeLab topology). - ### Alembic migration Single migration `20260517_phase7c_api_keys` that: @@ -77,7 +72,7 @@ Single migration `20260517_phase7c_api_keys` that: 1.
