+## Repository Role
+
+This repository contains the Windows client source code and build system.
+
+It owns:
+
+- client executable source
+- protocol/client networking code
+- UI/client runtime C++ modules
+- build-time tools such as client-side pack/proto helpers
+
+## Working Rules
+
+- Treat this repository as Windows-first.
+- Prefer protocol-safe, targeted changes over broad refactors.
+- Keep packet and login-flow changes aligned with `m2dev-server-src`.
+- Do not mix packed asset/data changes into this repository unless they are source-side build assets.
+
+## Build Notes
+
+Typical build entrypoint:
+
+```bash
+cmake -S . -B build
+cmake --build build
+```
+
+In practice, most real builds happen on Windows with Visual Studio toolchains.
+
+## High-Risk Areas
+
+- `src/UserInterface/Packet.h`
+- `AccountConnector`
+- `PythonNetworkStream*`
+- `NetStream`
+
+When changing login/auth/protocol behavior:
+
+- mirror the server-side packet expectations in `m2dev-server-src`
+- verify the live asset-side flow in `m2dev-client`
+- avoid silent header drift between client and server
+
+## Cross-Repo Boundaries
+
+- client executable and protocol code belong here
+- packed/unpacked client data under `assets/` belong in `m2dev-client`
+- server packet/auth implementation belongs in `m2dev-server-src`

+# CLAUDE.md
+
+Follow [AGENTS.md](AGENTS.md) as the canonical repo guide.
+
+Short version:
+
+- this is the Windows client source repo
+- protocol/login changes must stay aligned with `m2dev-server-src`
+- asset-side login/serverlist behavior lives in `m2dev-client`
+- avoid broad refactors unless the task is explicitly architectural

+  > Open up your terminal inside, or `cd` in your project's root working directory and initialize the build with this command:
+  >
+  > ```
+  > cmake -S . -B build
+  > ```
+  >
+  > A new `build` folder has been created in your project's root directory. This folder contains all the build files and configurations, along with the `sln` file to open the project in Visual Studio.

+  >
+  > Double click on that file to launch Visual Studio and load the project.
+  >
+  > In the Solution Explorer, select all the projects minus the container folders, right click on one of the selected items, and click **Properties**
+  >
+  > ![](https://metin2.download/picture/J6aHw6uw330DeqyTaw2ZDVgRcT9hr3hr/.png)
+  >
+  > Next, make sure that the following settings are adjusted like this:
+  >
+  > 1. **Windows SDK Version** should be the latest of Windows 10. It is not recommended to select any Windows 11 versions yet if avalable.
+  > 2. **Platform Toolset** is the most important part for your build to succeed! Select the highest number you see. **v145** is for Visual Studio 2026. If you are running Visual Studio 2022 you won't have that, you will have **v143**, select that one, same goes for older Visual Studio versions.
+  > 3. **C++ Language Standard** should be C++20 as it is the new standard defined in the CMakeList.txt files as well. Might as well set it like that for all dependencies.
+  > 4. **C Language Standard** should be C17 as it is the new standard defined in the CMakeList.txt files as well. Might as well set it like that for all dependencies.
+  >
+  > Once done, click Apply and then OK to close this dialog.
+  >
+  > ![](https://metin2.download/picture/2uacNZ4zOCYfI6vmigMTFwbuQ4tcmZ1C/.png)
+  >
+  > After that, in the toolbar at the top of the window, select your desired output configuration:
+  >
+  > ![](https://metin2.download/picture/cB0AGhHJ3TKFResDSeIgGmF7Vbo2SyGK/.png)
+  >
+  > Finally, click on the **Build** option at the top and select **Build Solution**, or simply press **CTRL+SHIFT+B** in your keyboard with all the projects selected.
+  >
+  > ![](https://metin2.download/picture/EN38Dz0Yef2edZ5Ptp4a5t4xWs1tr9V5/.png)
+  >
+  > **Note**: if this is **NOT** your first build after executing the `cmake -S . -B build` command for this workspace, it is recommended to click **Clean Solution** before **Build Solution**.
+  >
+  > <br>
+  >
+  > Where to find your compiled binaries:
+  >
+  > Inside the **build** folder in your cloned repository, you should have a **bin** folder and inside that, you should have a **Debug**, **Release**, **RelWithDebInfo** or **MinSizeRel** folder, depending on your build configuration selection.
+  >
+  > In that folder you should be seeing all your binaries:
+  >
+  > ![](https://metin2.download/picture/4cVxiU2Ac8CON58Gh70f6Do34dGBXpOz/.png)
+  >
+  > If you did **NOT** install the **Client** project yet, you are done here.
+  >
+  > If you **HAVE** the **Client** project installed, paste these 2 `.exe` files in these locations inside the Server project:
+  >
+  > - **Metin2_<Debug|Release|RelWithDebInfo|MinSizeRel>.exe**: inside root folder of the Client project
+  > - **PackMaker.exe**: inside `assets\PackMaker.exe`

+
+   In Python 3.0, this protection has two levels:
+   * normal anti-recursion protection is triggered when the recursion level
+     exceeds the current recursion limit. It raises a RecursionError, and sets
+     the "overflowed" flag in the thread state structure. This flag
+     temporarily *disables* the normal protection; this allows cleanup code
+     to potentially outgrow the recursion limit while processing the
+     RecursionError.
+   * "last chance" anti-recursion protection is triggered when the recursion
+     level exceeds "current recursion limit + 50". By construction, this
+     protection can only be triggered when the "overflowed" flag is set. It
+     means the cleanup code has itself gone into an infinite loop, or the
+     RecursionError has been mistakenly ignored. When this protection is
+     triggered, the interpreter aborts with a Fatal Error.
+
+   In addition, the "overflowed" flag is automatically reset when the
+   recursion level drops below "current recursion limit - 50". This heuristic
+   is meant to ensure that the normal anti-recursion protection doesn't get
+   disabled too long.
+
+   Please note: this scheme has its own limitations. See:
+   http://mail.python.org/pipermail/python-dev/2008-August/082106.html
+   for some observations.

+// Conceptually, critical sections are a deadlock avoidance layer on top of

+// otherwise thread-unsafe objects, such as dict.
+//
+// NOTE: These APIs are no-ops in non-free-threaded builds.

+// Straightforward per-object locking could introduce deadlocks that were not

+// to acquire the same locks in different orders, they would deadlock.
+//
+// One way to avoid deadlocks is to allow threads to hold only the lock (or
+// locks) for a single operation at a time (typically a single lock, but some
+// operations involve two locks). When a thread begins a nested operation it
+// could suspend the locks for any outer operation: before beginning the nested
+// operation, the locks for the outer operation are released and when the
+// nested operation completes, the locks for the outer operation are
+// reacquired.
+//
+// To improve performance, this API uses a variation of the above scheme.
+// Instead of immediately suspending locks any time a nested operation begins,
+// locks are only suspended if the thread would block. This reduces the number
+// of lock acquisitions and releases for nested operations, while still
+// avoiding deadlocks.
+//
+// Additionally, the locks for any active operation are suspended around
+// other potentially blocking operations, such as I/O. This is because the
+// interaction between locks and blocking operations can lead to deadlocks in
+// the same way as the interaction between multiple locks.
+//
+// Each thread's critical sections and their corresponding locks are tracked in
+// a stack in `PyThreadState.critical_section`. When a thread calls
+// `_PyThreadState_Detach()`, such as before a blocking I/O operation or when
+// waiting to acquire a lock, the thread suspends all of its active critical
+// sections, temporarily releasing the associated locks. When the thread calls
+// `_PyThreadState_Attach()`, it resumes the top-most (i.e., most recent)
+// critical section by reacquiring the associated lock or locks.  See
+// `_PyCriticalSection_Resume()`.
+//
+// NOTE: Only the top-most critical section is guaranteed to be active.
+// Operations that need to lock two objects at once must use
+// `Py_BEGIN_CRITICAL_SECTION2()`. You *CANNOT* use nested critical sections
+// to lock more than one object at once, because the inner critical section
+// may  suspend the outer critical sections. This API does not provide a way
+// to lock more than two objects at once (though it could be added later
+// if actually needed).
+//
+// NOTE: Critical sections implicitly behave like reentrant locks because
+// attempting to acquire the same lock will suspend any outer (earlier)
+// critical sections. However, they are less efficient for this use case than
+// purposefully designed reentrant locks.
+//
+// Example usage:
+//  Py_BEGIN_CRITICAL_SECTION(op);
+//  ...
+//  Py_END_CRITICAL_SECTION();
+//
+// To lock two objects at once:
+//  Py_BEGIN_CRITICAL_SECTION2(op1, op2);
+//  ...
+//  Py_END_CRITICAL_SECTION2();
