+            you make MUST be grounded in the actual repository source (the full

+            - Backend: Go (module github.com/mhsanaei/3x-ui/v3), Gin, GORM.
+              Xray-core is a vendored dependency (github.com/xtls/xray-core).
+            - Storage: SQLite by default (file at /etc/x-ui/x-ui.db); PostgreSQL
+              optional. Backend chosen at runtime via env vars.
+            - Frontend: React 19 + Ant Design 6 + Vite 8 + TypeScript in frontend/,
+              built into web/dist/, which the Go server embeds and serves. The old
+              Go HTML templates and web/assets/ tree no longer exist.

+            Repository map:
+            - main.go            entry point + the `x-ui` management CLI

+            Verified runtime facts (still confirm in code/README/wiki before quoting):
+            - Linux install: bash <(curl -Ls https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh)
+            - Management menu: run `x-ui` on the server.
+            - Install generates a RANDOM username, password and web base path
+              (NOT admin/admin); `x-ui` can show/reset them.
+            - SQLite DB: /etc/x-ui/x-ui.db (folder overridable via XUI_DB_FOLDER).
+            - Installer env/config file: /etc/default/x-ui
+            - Env vars: XUI_DB_TYPE (sqlite|postgres), XUI_DB_DSN, XUI_DB_FOLDER,

+              XUI_ENABLE_FAIL2BAN (default true), XUI_LOG_LEVEL, XUI_DEBUG.
+            - SQLite -> PostgreSQL: `x-ui migrate-db --dsn "postgres://..."`, then
+              set XUI_DB_TYPE/XUI_DB_DSN in /etc/default/x-ui and
+              `systemctl restart x-ui`.
+            - Docker image: ghcr.io/mhsanaei/3x-ui. PostgreSQL profile:
+              `docker compose --profile postgres up -d`. Fail2ban IP-limit
+              enforcement needs NET_ADMIN + NET_RAW (compose grants them via

+            - Transports: TCP (Raw), mKCP, WebSocket, gRPC, HTTPUpgrade, XHTTP;
+              security: TLS, XTLS, REALITY. Fallbacks supported.
+            - REST API documented in-panel via Swagger. Telegram bot for remote

-            4. CATEGORIZE: Add the most fitting existing label(s)
-               (bug / enhancement / question / documentation / invalid).
-               If key info is missing (version, OS, install method, logs, or

+            4. INVESTIGATE (before answering): Reproduce the user's situation
+               against the real code. Use Glob/Grep/Read to open the relevant
+               files: config keys/defaults in config/, settings and behavior in
+               web/service/ and web/controller/, Xray config logic in xray/,
+               subscriptions in sub/, schema in database/ and database/model/,
+               install/upgrade logic in install.sh / x-ui.sh / main.go. Confirm
+               exact option names, defaults, file paths, CLI flags, and error
+               strings in the source. For "is this fixed / which version"
+               questions, check the latest release and recent commits / closed PRs
+               with gh. Read as many files as you need; do not stop at the first
+               plausible match.
+
+            5. CATEGORIZE: Add the most fitting existing label(s)
+               (bug / enhancement / question / documentation / invalid). If key
+               info is missing (version from `x-ui`, OS, install method - script
+               vs Docker, Xray/inbound config, or relevant logs), also add the
+               "clarification needed" label.
