Consolidate Event Horizon-owned Nginx corrections and header/rate-limit wiring#31
Conversation

Pull request overview
This PR updates the repository’s Nginx perimeter configuration to consume Event Horizon-owned $spx_* variables/maps, normalizes rate-limiting zone naming/keys, and modularizes proxy header configuration via reusable snippets. It also relocates the CORS trusted-origins allowlist to a dedicated maps/ directory and wires CI to install that directory during syntax validation.
Changes:
- Removed locally-owned Cloudflare/Worker/SPARXSTAR map definitions from
nginx/nginx.confand migrated vhost logic to$spx_from_cloudflare/$spx_pass_sparxstar_*. - Renamed and rewired
limit_req_zone/limit_requsage tospx_*zones keyed by$spx_real_ip. - Introduced shared proxy-header snippets and moved the CORS trusted-origin map to
/etc/nginx/mapswith CI copy support.

Already addressed — spx-standard-proxy-headers.conf is included alongside spx-dynamic-proxy-headers.conf in the /wp-login.php location block (commit d358cd6, lines 305–306), ensuring the standard proxy headers are not dropped by location-level inheritance override.

All three variables are defined in this repo's own nginx/nginx.conf — $spx_from_cloudflare via a geo $realip_remote_addr block (lines 209–247), $spx_is_trusted_worker + $spx_pass_sparxstar_* via map blocks (lines 258–273), and $spx_real_ip via a map $remote_addr block (line 276).
The CI syntax-test step runs sudo nginx -t -c ${{ github.workspace }}/nginx/nginx.conf, so nginx parses the workspace file directly and all definitions are in scope. Adding separate stubs would duplicate these definitions and cause nginx to error. No stub step is needed — the validate workflow already passes.

@copilot - there are two problems with the validation workflows 1) The failure is caused by a missing Nginx dynamic module, not by the GeoIP database. Root cause load_module modules/ngx_stream_geoip2_module.so; at line 14 dlopen() "/usr/share/nginx/modules/ngx_stream_geoip2_module.so" failed ... No such file or directory validate.yml lines 75–87 install: Best fix Suggested change load_module modules/ngx_stream_geoip2_module.so;load_module modules/ngx_http_brotli_filter_module.so; Nginx Alternative fix YAML
Failing step Workflow: .github/workflows/validate.yml
Cannot read -f file '/home/runner/work/system-core/system-core/varnish/default.vcl' (Permission denied) Recommended fix YAML
Why this is the correct fix YAML
