 # PROJECT KNOWLEDGE BASE
 
-**Generated:** Sat Jan 24 2026
-**Context:** Monorepo for Flux Panel (Traffic Forwarding)
+**Generated:** Mon Feb 02 2026
+**Commit:** 7ca01ab
+**Branch:** beta
 
 ## OVERVIEW
-Flux Panel is a traffic forwarding management system based on [go-gost](https://github.com/go-gost/gost). It manages tunnels, port forwarding, and user quotas.
-**Stack:** Monorepo (Java/Spring Boot Backend + React/Vite Frontend + Go/GOST Service).
+Flux Panel is a traffic forwarding management system built on a forked GOST v3 stack. It ships as Dockerized Spring Boot (admin API) + Vite/React UI + Go forwarding agent, with optional mobile WebView wrappers.
 
 ## STRUCTURE
 ```

 ## WHERE TO LOOK
 | Task | Location | Notes |
 |------|----------|-------|
-| **Admin API** | `springboot-backend/` | Users, quotas, billing logic |
-| **UI/Dashboard** | `vite-frontend/` | Management console |
-| **Core Forwarding** | `go-gost/` | GOST implementation & extensions |
-| **Deploy** | `docker-compose-v4.yml` | Container orchestration |
+| **Deploy (Docker)** | `docker-compose-v4.yml` | Env: `JWT_SECRET`, `BACKEND_PORT`, `FRONTEND_PORT` |
+| **Deploy (IPv6)** | `docker-compose-v6.yml` | Same as v4 + IPv6-enabled bridge |
+| **Panel install** | `panel_install.sh` | Picks v4/v6, generates `JWT_SECRET`, downloads compose |
+| **Node install** | `install.sh` | Installs `/etc/flux_agent/flux_agent` + writes `config.json`/`gost.json` + systemd `flux_agent.service` |
+| **Admin API entry** | `springboot-backend/src/main/java/com/admin/AdminApplication.java` | Spring Boot app |
+| **Admin API routes** | `springboot-backend/src/main/java/com/admin/controller/` | Mostly `/api/v1/*` controllers |
+| **Admin auth** | `springboot-backend/src/main/java/com/admin/common/interceptor/JwtInterceptor.java` | Checks `Authorization` header |
+| **Web UI routing** | `vite-frontend/src/App.tsx` | React Router v6 + ProtectedRoute/H5 layouts |
+| **Web UI API client** | `vite-frontend/src/api/network.ts` | Axios `baseURL` + `Authorization` header |
+| **Go agent entry** | `go-gost/main.go` | Reads panel `config.json` + starts gost services |
+| **Go x fork** | `go-gost/x/` | Handlers/listeners/dialers + management API |
 
 ## CONVENTIONS
-- **Monorepo**: 3 distinct languages/stacks. Treat each subdir as a separate project.
-- **Docker**: Primary deployment method.
-- **Scripts**: `panel_install.sh` for panel, `install.sh` for nodes.
+- `Authorization` header carries the raw JWT token (no `Bearer` prefix) between `vite-frontend/` and `springboot-backend/`.
+- `go-gost/` uses `replace github.com/go-gost/x => ./x` and `go-gost/x/` is also its own Go module.
+
+## ANTI-PATTERNS (THIS PROJECT)
+- Do not edit generated protobuf output: `go-gost/x/internal/util/grpc/proto/*.pb.go`, `go-gost/x/internal/util/grpc/proto/*_grpc.pb.go`.
 
 ## COMMANDS
 ```bash
-# Quick Deploy (Panel)
-./panel_install.sh
+# Panel (Docker)
+docker compose -f docker-compose-v4.yml up -d
+docker compose -f docker-compose-v6.yml up -d
 
-# Quick Deploy (Node)
+# Release-based install scripts
+./panel_install.sh
 ./install.sh
 
-# Docker
-docker-compose -f docker-compose-v4.yml up -d
+# Local dev (per subproject)
+(cd springboot-backend && mvn clean package)
+(cd vite-frontend && npm run dev)
+(cd go-gost && go run .)
 ```
+
+## NOTES
+- LSP servers are not installed in this environment (gopls/jdtls/typescript-language-server); rely on grep-based navigation.
+- `vite-frontend/vite.config.ts` sets `minify: false` and disables treeshake; expect larger bundles.

 # GO-GOST SERVICE KNOWLEDGE BASE
 
+**Generated:** Mon Feb 02 2026
+
 ## OVERVIEW
-Core forwarding service based on GOST v3.
-**Stack:** Go 1.23, GOST Core v0.3.1, GOST x (Extensions).
+Forwarding agent built on GOST v3 with a local fork of `github.com/go-gost/x` under `x/`.
+**Stack:** Go 1.23, github.com/go-gost/core v0.3.1, local `go-gost/x` module.

 ```
 
+## WHERE TO LOOK
+| Task | Location | Notes |
+|------|----------|-------|
+| Panel integration config | `go-gost/config.go` | Expects `config.json` in cwd by default |
+| Service lifecycle/reload | `go-gost/program.go` | Parses config; handles SIGHUP reload |
+| WebSocket reporting | `go-gost/main.go` | Starts reporter + sets HTTP report URL |
+| Protocol behaviors | `go-gost/x/` | Handlers/listeners/dialers live here |
+
 ## CONVENTIONS
-- **Local Replace**: `go.mod` uses `replace github.com/go-gost/x => ./x`.
-- **Extensions**: Custom logic lives in `x/`. This is the primary place for modifications.
-- **Handlers**: Implements SOCKS5, Tunnel, Relay, etc.
+- 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.

+# GO-GOST REGISTRY KNOWLEDGE BASE
+
+**Generated:** Wed Feb 04 2026
+
+## OVERVIEW
+Central registration point for all pluggable GOST components (handlers, listeners, dialers, etc.).
+Allows the configuration system to resolve string types (e.g., "socks5") to actual Go implementations.
+
+## STRUCTURE
+One file per component type, exporting a standard Registry interface.
+```
+go-gost/x/registry/
+├── handler.go    # RegisterHandler(name, newFunc)
+├── listener.go   # RegisterListener(name, newFunc)
+├── dialer.go     # RegisterDialer(name, newFunc)
+└── ...           # Same pattern for auth, bypass, admission
+```
+
+## WHERE TO LOOK
+| Task | Location | Notes |
+|------|----------|-------|
+| Register a new component | `go-gost/x/registry/{type}.go` | Use `Register{Type}(name, creator)` |
+| Component lookup | `go-gost/x/registry/{type}.go` | `Get{Type}(name)` returns the creator function |
+| Default registrations | `go-gost/x/` (init functions) | Most components register themselves in their package `init()` |
+
+## CONVENTIONS
+- Thread-safe maps used for storage.
+- Names are case-sensitive (usually lowercase).
+- Components must be registered *before* the configuration parser runs (usually done via `import _ "..."` in `main.go`).

 ## CONVENTIONS
-- **DB**: SQLite used via `sqlite-jdbc`.
-- **ORM**: MyBatis Plus + MyBatis Plus Join.
-- **JSON**: FastJSON2 used for serialization.
-- **Utils**: Hutool used extensively.
-- **Auth**: Likely custom or token-based (see `controller` logic).
+- **DB**: SQLite URL is `jdbc:sqlite:${DB_PATH:/app/data/gost.db}` (`springboot-backend/src/main/resources/application.yml`).
+- **Auth**: JWT in `Authorization` header; enforced by `com.admin.common.interceptor.JwtInterceptor` for `/api/**` (with explicit excludes in `com.admin.config.WebMvcConfig`).
+- **Roles**: `@RequireRole` means admin-only (`role_id == 0`) via `com.admin.common.aop.RoleAspect`.
+- **Responses**: Controllers return `com.admin.common.lang.R` (`code == 0` success).
+- **CORS**: Allow-all origins; `Authorization` is exposed (`com.admin.config.WebMvcConfig`).

+# SPRINGBOOT BACKEND (com.admin) KNOWLEDGE BASE
+
+## OVERVIEW
+Primary Java code for the admin API. Controllers expose `/api/v1/*` endpoints and return `R` response envelopes.
+
+## STRUCTURE
+```
+springboot-backend/src/main/java/com/admin/
+├── controller/  # REST controllers (e.g., /api/v1/user)
+├── service/     # Business logic interfaces + impl/
+├── mapper/      # MyBatis Plus mappers
+├── entity/      # DB entities
+├── config/      # WebMvc/JWT/CORS/WebSocket config
+└── common/      # DTOs, auth, exception handling, utilities
+```
+
+## WHERE TO LOOK
+| Task | Location | Notes |
+|------|----------|-------|
+| User/login endpoints | `springboot-backend/src/main/java/com/admin/controller/UserController.java` | `/api/v1/user/*` |
+| Auth enforcement | `springboot-backend/src/main/java/com/admin/config/WebMvcConfig.java` | Intercepts `/api/**`, excludes login/config/captcha |
+| JWT validation | `springboot-backend/src/main/java/com/admin/common/interceptor/JwtInterceptor.java` | Requires `Authorization` header |
+| Admin-only ops | `springboot-backend/src/main/java/com/admin/common/annotation/RequireRole.java` | Enforced by `RoleAspect` |
+| Response envelope | `springboot-backend/src/main/java/com/admin/common/lang/R.java` | `code == 0` success |
+| Global error handling | `springboot-backend/src/main/java/com/admin/common/exception/GlobalExceptionHandler.java` | Maps exceptions -> `R.err(...)` |
+
+## CONVENTIONS
+- Controllers are mostly `@PostMapping` (even for list/get/delete) and use `/api/v1/*` prefixes.
+- JWT is custom (no 3p lib) and includes `role_id` in payload (`springboot-backend/src/main/java/com/admin/common/utils/JwtUtil.java`).
+
+## ANTI-PATTERNS
+- Do not change auth header format lightly: frontend expects `Authorization: <token>` (no `Bearer`).
