Post-review hardening (both fail-safe, not bugs):
- _client_ip normalizes IPs via ipaddress and unwraps IPv4-mapped IPv6, so a plain
TRUSTED_PROXY_IPS=10.10.0.1 also matches a peer surfaced as ::ffff:10.10.0.1 (a
Docker/IPv6 self-host footgun that would otherwise silently collapse everyone into
one rate-limit bucket).
- entrypoint.sh + _client_ip docstring: explicit warning never to add uvicorn
--proxy-headers, which would rewrite request.client from the forgeable XFF and defeat
the trust check.
