Implementation Status vs Design

This document tracks current implementation status against the original design in docs/implementation_notes.md.

Matches the design

• Workspace layout with feature crates (wtfnet-core, wtfnet-platform, wtfnet-geoip, wtfnet-probe, wtfnet-dns, wtfnet-http, wtfnet-tls, wtfnet-discover, wtfnet-diag).
• CLI remains a thin wrapper around library crates.
• Platform abstraction uses traits with OS dispatch.
• GeoIP: local GeoLite2 Country + ASN support.
• Probe: ping/tcping/trace with GeoIP enrichment.
• DNS: Hickory-based query/detect with best-effort heuristics.
• HTTP: head/get via reqwest with best-effort timing breakdown and optional HTTP/3 (feature-gated).
• TLS: rustls-based handshake/verify/cert/alpn.
• Discover: mDNS/SSDP bounded collection.
• Diag: bundle export in zip.

Deviations or refinements

• DNS adds DoT/DoH and SOCKS5 proxy support.
• HTTP/TLS/TCP ping include SOCKS5 proxy support.
• HTTP timing breakdown is best-effort: dns_ms/ttfb_ms are captured; connect_ms/tls_ms are measured via a separate probe and can be null with warnings.
• DNS watch uses pnet and is feature-gated as best-effort.

Gaps vs design (as of now)

• HTTP/3 is feature-gated and incomplete; not enabled in default builds.
• TLS verification is rustls-based (no OS-native verifier).
• Discover does not include LLMNR/NBNS.

Current stage summary

• v0.1 scope is complete.
• v0.2 scope mostly complete; remaining are deeper test coverage and optional enhancements.
