Windows / WSL network path diagnostics and safe repair for DeepSeek Harness.

Highlights

• Two runtime models only — automatically detects WINDOWS_NATIVE or
  WSL_DISTRIBUTION; no manual Windows/WSL mode switch.
• DSH path graph — shows the actual DSH network path, DNS side branch and
  first failing edge; a TUN/VPN adapter is chained with the physical uplink
  NIC and the real gateway behind it.
• Configuration Drift — finds stale proxy configuration without treating
  healthy configuration differences as errors.
• Single / stability checks — one-shot diagnostics plus repeated TCP/HTTP
  sampling; DeepSeek is the default target and switching is always available.
  Every probe layer and the whole check carry hard timeouts, so a broken
  network never stalls the page.
• Agent-ready report — one click copies a stable-format Markdown report
  (fixed English headers, report-version, TL;DR first, machine-readable
  codes and per-layer probe latency).
• Recommended repairs — only high-confidence diagnoses mapped to common
  low-risk operations (clear proxy-residue env vars, disable system proxy,
  flush DNS cache); admin and high-risk operations stay in the manual catalog.
• Safe repair — snapshot → diff → confirm → apply → re-detect, with
  rollback for persistent changes.
• DSH-native UI — uses DSH primitives and --dsw-* tokens only.

Screenshots

The plugin lives in **DSH Settings → Plugins → Network** (click images to enlarge)
DSH inside a WSL distribution: DSH → distro → WSL NAT → Windows Host → proxy TUN → physical NIC → gateway → target	Windows-native DSH path, chaining the physical uplink behind a TUN/VPN adapter
Grouped network configuration	**Network configuration** is grouped by source, every entry traceable: - **Windows proxy**: WinINet / WinHTTP state, proxy environment variables across all three scopes (both letter cases) - **DSH process environment**: runtime model, egress (direct / via proxy with address), **verified listener process** behind the proxy port, process proxy variables - **WSL**: distribution environment, network mode (NAT / mirrored), `/etc/wsl.conf` and `.wslconfig` - **Advanced**: DNS cache, interfaces & routes, Hosts, first-aid actions Every persistent change follows snapshot → preview → confirm → apply → rollback.

Install

dsh plugin --profile web add dsh-network-settings
