The PHP app, Apache, and .htaccess are replaced by a single Go binary (standard library only). Routing, the JSON response, the landing page, the shared email design, and all four parsers are ported with the same output; JSON object keys are kept in sender order via an ordered decoder. - mail.go: SMTP delivery with quoted-printable body and RFC 2047 subject - main.go: routing, client IP from the proxy, /healthz, -check flag - render.go: email shell, escaping, table helpers, generic renderer - parser_*.go: github, grafana, json, wxinteract - main_test.go: handler, response shape, IP forwarding, every parser - Dockerfile: multi-stage build to distroless static, non-root, HEALTHCHECK - deploy/webhooks.dixon.cx.service: systemd unit for the container - README and PARSER_PROMPT updated for Go; IMPLEMENTATION_SUMMARY removed
