DoH at /dns-query, admin UI at random /adg-<rand>/ path. AGH binds
localhost only (web UI + plain DNS on random ports); nginx bridges both
paths on the existing panel vhost, so no new domain, cert, or open port.
Config pre-seeded (no wizard), bcrypt password via htpasswd, re-run
safe, -uninstall y supported.

Host ALPN: ws/xhttp/trojan hosts now advertise ["h2","http/1.1"];
reality host gets [] (its ALPN comes from the reality stream).
Diagnostics access: opening the diag path directly without the
diag_key cookie previously 404'd, so a bookmarked link only worked
after manually visiting /<panel_path>/diag. Now the diag page
302-bounces unauthenticated hits through the SSO bridge, which
validates the 3x-ui panel session and mints the cookie, then redirects
back - so the link works once you're logged into the panel. API and
asset sub-locations still 404 without the cookie (only the HTML page
redirects, never XHR/asset requests).
Verified end to end with nginx + the auth semantics of the installed
3x-ui v3.4.2: logged-in raw hit resolves to the page with no loop,
anonymous hit lands on the panel login.

3x-ui now renders share-link endpoints from the hosts table, which
supersedes the legacy externalProxy arrays in stream_settings. Remove
those arrays from all four inbounds and insert one host per inbound
instead (inbound_id resolved by tag):
- REALITY: panel domain, 443, security=same (inherits reality params)
- ws / xhttp / trojan-grpc: panel domain, 443, security=tls,
fingerprint firefox
Also switch the REALITY inbound uTLS fingerprint from chrome to
firefox to match.

The 3x-ui session cookie is Path-scoped to the panel base path, so the
diag vhost locations can never see it directly. Instead a bridge
location under the panel path (/<panel_path>/diag) validates the
session with auth_request against GET <basePath>/panel/ (sent with
X-Requested-With: XMLHttpRequest so 3x-ui answers 401 instead of a
login redirect), then issues a path-scoped diag_key cookie and
redirects to the diagnostics page. All diag locations return 404
without that cookie.
auth_request runs in the access phase while "return" runs in the
rewrite phase, so the success path hops through try_files to a named
location; the cookie is set only there, never on the 401 redirect.
Replaces the previous ?key= token link, which is removed entirely.

Bug fixes:
- Root check: exit with message instead of "sudo su -" (which continued
the script as non-root after the shell exited)
- Move destructive cleanup into clean_previous_install(), called after
domain validation - wrong args no longer wipe a working install
- x25519 keygen: use xray-linux-$(_arch) instead of hardcoded amd64,
with fallback for renamed ARM binaries
- Cert renewal: certs are standalone-issued, so renew with pre/post
hooks stopping nginx instead of --nginx (which could not bind :80)
- Drop ngx_stream_geoip2 load_module insertion: module was never
installed or used and broke nginx -t when the .so was absent
- emoji_flag: 10s curl timeout + fallback when ipwho.is unavailable
- Uninstall: rm -f /usr/bin/x-ui (trailing slash made rm fail on file)
nginx >= 1.25.1 deprecates "listen ... http2"; emit "http2 on;" there
and keep the old syntax on older versions (Debian 12, Ubuntu 24.04).
Results screen: drop certbot/ssl cert dumps and Clash sub links, keep
panel URL + credentials + diagnostics. Update CLAUDE.md to current
repo state.
