Add ReadHeaderTimeout and IdleTimeout to the http.Server (named constants beside the existing timeouts) to close the slowloris and idle-keep-alive gaps. Add a SecurityHeaders middleware setting HSTS, a JSON-API CSP (default-src 'none'; frame-ancestors 'none'), X-Frame-Options: DENY, X-Content-Type-Options: nosniff, Referrer-Policy, and Permissions-Policy. It is registered before CORS so the headers ride on preflight responses. Resolve the client IP from X-Forwarded-For / X-Real-IP only when the direct peer is in a trusted-proxy allowlist, defaulting to loopback plus RFC1918 and configurable via TRUSTED_PROXIES; an untrusted peer's forwarded headers are ignored and the direct peer is logged. Uses net/netip; no new dependency. Model: opus-4-8
