Proxy chain diagnostics
This audit checks whether the edge-side public IP from each chain lines up with corroborating edge signals such as REMOTE_ADDR, X-Real-IP, CF-Connecting-IP, or True-Client-IP. Edge mismatches often mean the chain order is wrong, the proxy is appending or prepending unexpectedly, or the header is partially spoofed.
