Verified live 2026-08-31: guarded path serves the Anubis JS challenge at
HTTP 200 to non-browser API clients (status-only consumers silently get
HTML); direct published port 8081 from pass_ip sources returns real JSON.
Decision: no second agent-only instance — same engines and same
rate-sensitive VPN exit IP would see double request volume for zero gain.
Server-side implementation landed on Dankclaw: dedicated 'tunnel' account
(nologin shell, password-locked, key-only auth), sshd drop-in
99-tunnel.conf scoping AllowTcpForwarding to that user with PermitTTY off,
and permitopen="localhost:8787" key-option guidance so a leaked tunnel key
can only forward to the webui port. WebUI stays loopback-only published.
All in-repo path references (AGENTS.md, README, old scripts, report artifacts,
test code paths) rewritten in the same commit; focused-test map extended for
.gitignore, old/scripts/*, dankclaw/comfyui/*, and report/* per this repo's
own convention ('add one before committing'). Obsidian wikilinks are
title-based and unaffected.
