 - **Flat Monorepo**: Language-prefixed dirs (`go-backend`, `go-gost`, `vite-frontend`) instead of `apps/`/`libs/`.
 - **Asymmetric Go Layout**: `go-backend` follows `cmd/<app>/main.go` while `go-gost` uses `root/main.go`.
 - **Frontend Hybrid Mode**: `App.tsx` detects "H5 mode" (mobile WebView) vs desktop, dictating layout strategy.
+- **Experimental Bundler**: `vite-frontend` uses `rolldown-vite` (Rust-based) instead of standard Vite.
+- **Non-minified Builds**: `vite.config.ts` sets `minify: false`, `treeshake: false` for debugging.

 ## CONVENTIONS
 - Two configs exist: panel integration uses `config.json`; forwarding services use GOST config (defaults to `gost.{json,yaml}` via viper search paths).
 - `go-gost/x/` is the primary extension surface; avoid editing vendored deps.
 - Agent communicates with panel via WebSocket (real-time commands) + HTTP (batch traffic reports).
 - All panel communication uses AES encryption with node `secret` as PSK.
+- CI builds with `CGO_ENABLED=0` for static binaries, then compresses with UPX.
 
 ## ANTI-PATTERNS
 - **DO NOT EDIT** generated protobuf in `x/internal/util/grpc/proto/`.
