+
+## Critical Architecture Patterns
+
+**Telegram Bot Restart Pattern**: MUST call `service.StopBot()` before any server restart (SIGHUP or shutdown) to prevent Telegram bot 409 conflicts. This is critical in `main.go` signal handlers (lines 82-84, 120-122).
+
+**Embedded Assets**: All web resources (HTML, CSS, JS, translations in `web/translation/`) are embedded at compile time using `//go:embed`. Changes to these files require full recompilation - no hot-reload available.
+
+**Dual Server Design**: Main web panel and subscription server run concurrently, both managed by `web/global` package. Subscription server uses separate port.
+
+**Database Seeder System**: Uses `HistoryOfSeeders` model to track one-time migrations (e.g., password bcrypt migration). Check this table before running migrations to prevent re-execution.
+
+**Xray Integration**: Panel dynamically generates `config.json` from inbound/outbound settings and communicates via gRPC API (`xray/api.go`) for real-time traffic stats. Xray binary is platform-specific (`xray-{os}-{arch}`) and managed by installer scripts.
+
+**Signal-Based Restart**: SIGHUP triggers graceful restart. Always stop Telegram bot first via `service.StopBot()`, then restart both web and sub servers.
+
+## Build & Development Commands
+
+```bash
+# Build (creates bin/3x-ui.exe)
+go build -o bin/3x-ui.exe ./main.go
+
+# Run with debug logging
+XUI_DEBUG=true go run ./main.go
+
+# Test all packages
+go test ./...
+
+# Vet code
+go vet ./...
+```
+
+**Production Build**: Uses CGO_ENABLED=1 with static linking via Bootlin musl toolchains for cross-platform builds (see `.github/workflows/release.yml`).
+
+## Configuration & Environment
+
+**Environment Variables**:
+- `XUI_DEBUG=true` - Enable detailed debug logging
+- `XUI_LOG_LEVEL` - Set log level (debug/info/notice/warning/error)
+- `XUI_MAIN_FOLDER` - Override default installation folder
+- `XUI_BIN_FOLDER` - Override binary folder (default: "bin")
+- `XUI_DB_FOLDER` - Override database folder (default: `/etc/x-ui` on Linux)
+- `XUI_LOG_FOLDER` - Override log folder (default: `/var/log/x-ui` on Linux)
+
+**Database Path**: `config.GetDBPath()` returns `/etc/x-ui/x-ui.db` on Linux, current directory on Windows. GORM models auto-migrate on startup.
+
+**Listen Address**: If inbound listen field is empty, defaults to `0.0.0.0` for proper dual-stack IPv4/IPv6 binding (see `database/model/model.go` lines 85-87).
+
+## Project-Specific Patterns
+
+**IP Limitation**: Implements "last IP wins" strategy. When client exceeds LimitIP, oldest connections are automatically disconnected via Xray API to allow newest IPs.
+
+**Session Management**: Uses `gin-contrib/sessions` with cookie-based store for authentication.
+
+**Internationalization**: Translation files in `web/translation/translate.*.toml`. Access via `I18nWeb(c, "key")` in controllers using `locale.I18nType` enum.
+
+**Job Scheduling**: Uses `robfig/cron/v3` for periodic tasks (traffic monitoring, CPU checks, LDAP sync, IP tracking). Jobs registered in `web/web.go` during server initialization.
+
+**Service Layer Pattern**: Services inject dependencies (like `xray.XrayAPI`) and operate on GORM models. Example: `InboundService` in `web/service/inbound.go`.
+
+**Controller Pattern**: Controllers use Gin context (`*gin.Context`) and inherit from `BaseController`. Check auth via `checkLogin` middleware.
+
+**Xray Binary Management**: Download platform-specific Xray binary to bin folder during installation. GeoIP/GeoSite rules downloaded from external repositories (Loyalsoldier, chocolate4u, runetfreedom).
+
+## Gotchas
+
+1. **Bot Restart**: Always stop Telegram bot before server restart to avoid 409 conflict
+2. **Embedded Assets**: Changes to HTML/CSS/JS require recompilation
+3. **Password Migration**: Seeder system tracks bcrypt migration - check `HistoryOfSeeders` table
+4. **Port Binding**: Subscription server uses different port from main panel
+5. **Xray Binary**: Must match OS/arch exactly - managed by installer scripts
+6. **No Test Files**: Project currently has no `_test.go` files, though `go test ./...` is available

+## Development commands
+
+- Build the app: `go build -o bin/3x-ui.exe ./main.go`
+- Run locally with debug logging: `XUI_DEBUG=true go run ./main.go`
+- Run tests: `go test ./...`
+- Run vet: `go vet ./...`
+- Run a single package test suite: `go test ./path/to/package`
+- Run a single test: `go test ./path/to/package -run TestName`
+- Show CLI help / subcommands: `go run ./main.go --help`
+- Show version: `go run ./main.go -v`
+
+VS Code tasks mirror the common Go workflows:
+- `go: build`
+- `go: run`
+- `go: test`
+- `go: vet`
+
+## Runtime shape
+
+This is a Go monolith for managing Xray-core, with two Gin-based HTTP servers started from `main.go`:
+- the main panel server in `web/`
+- the subscription server in `sub/`
+
+`main.go` initializes the SQLite database, starts both servers, and handles process signals:
+- `SIGHUP` restarts the panel + subscription servers
+- `SIGUSR1` restarts xray-core only
+
+Important: before full shutdown or SIGHUP restart, the Telegram bot is stopped explicitly via `service.StopBot()` to avoid Telegram 409 conflicts.
+
+## High-level architecture
+
+### Database and settings
+
+- `database/db.go` initializes GORM with SQLite, runs auto-migrations, seeds the default admin user, and runs one-time seeders.
+- Models live in `database/model/model.go`.
+- App configuration is heavily database-backed through the `settings` table rather than static config files.
+- `HistoryOfSeeders` is used to track one-time migrations such as password hashing changes.
+
+### Web panel
+
+- `web/web.go` builds the main Gin engine, session middleware, gzip, i18n, static asset serving, template loading, websocket hub setup, and background cron jobs.
+- Controllers are in `web/controller/`.
+- Business logic lives in `web/service/`.
+- Background tasks live in `web/job/`.
+- The websocket hub is in `web/websocket/` and is wired from `web/web.go`.
+
+### Subscription server
+
+- `sub/sub.go` starts a separate Gin server for subscription links and JSON subscriptions.
+- It has its own listen/port/cert settings and can run independently of the main panel routes.
+- It reuses embedded templates/assets from `web/` and applies subscription-specific path/domain settings from the database.
+
+### Xray integration
+
+- `xray/` is the bridge to xray-core.
+- `xray/process.go` writes `config.json`, launches the platform-specific xray binary, tracks process state, and handles stop/restart behavior.
+- `xray/api.go`, `xray/traffic.go`, and related files handle API access and traffic/stat collection.
+- The panel treats xray-core as a managed subprocess and periodically monitors/restarts it from cron jobs in `web/web.go`.
+
+### Frontend delivery model
+
+- The UI is server-rendered HTML templates plus embedded static assets under `web/html/` and `web/assets/`.
+- In production, templates/assets are embedded with `go:embed` in `web/web.go`.
+- In debug mode (`XUI_DEBUG=true`), templates and assets are loaded from disk, so edits under `web/html/` and `web/assets/` are reflected without rebuilding embedded resources.
+- Internationalization files live in `web/translation/*.toml` and are initialized by `web/locale`.
+
+## Background jobs and long-running behavior
+
+`web/web.go` registers the operational jobs that keep the panel in sync with xray-core. These include:
+- xray process health checks
+- deferred/statistical traffic collection
+- client IP checks / log maintenance
+- periodic traffic reset jobs
+- optional LDAP sync
+- optional Telegram notification and CPU alert jobs
+
+When changing settings or services that affect runtime behavior, check whether a cron job, websocket update, or xray restart path also needs to change.
+
+## Repo-specific conventions and gotchas
+
+- Default credentials are seeded as `admin` / `admin`, but stored hashed in the DB.
+- The app uses DB settings extensively; many behavior changes require updating `SettingService`, not just editing route/controller code.
+- The `Inbound` model stores much of the Xray config as JSON strings (`Settings`, `StreamSettings`, `Sniffing`), then converts those into xray config structs.
+- The main panel and subscription server have separate listen/port/cert/base-path concepts. Keep them distinct when changing routing or TLS behavior.
+- Session handling uses `gin-contrib/sessions` with a cookie store and secret loaded from settings.
+- The subscription server intentionally runs Gin in release mode and discards Gin default writers.
+- There are currently no `*_test.go` files in the repo, so `go test ./...` mainly validates buildability of packages.
+
+## Important files to orient quickly
+
+- `main.go` — process entrypoint, CLI subcommands, signal handling
+- `web/web.go` — main server wiring, embedded assets/templates, cron jobs
+- `sub/sub.go` — subscription server wiring
+- `database/db.go` — DB init, migrations, seeders
+- `database/model/model.go` — core persistent models
+- `web/service/setting.go` — central behavior/settings access point
+- `web/service/inbound.go` and `web/service/xray.go` — panel logic tied to xray config/runtime
+- `xray/process.go` — xray subprocess management
+
+## Existing repo guidance carried forward
+
+From `.github/copilot-instructions.md` and current code structure:
+- Treat the project as a Go + Gin + SQLite application with embedded web assets.
+- Remember the dual-server design: main panel plus subscription server.
+- Preserve the Telegram bot shutdown-before-restart behavior.
+- If working on deployment or container behavior, note that Docker support exists via `Dockerfile`, `DockerInit.sh`, `DockerEntrypoint.sh`, and `docker-compose.yml`.
