+# Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our community a harassment-free experience for everyone, regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, level of experience, education, socio-economic status, nationality, personal appearance, race, caste, color, religion, or sexual identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming, diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes, and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of acceptable behavior and will take appropriate and fair corrective action in response to any behavior that they deem inappropriate, threatening, offensive, or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, and will communicate reasons for moderation decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing the community in public spaces. Examples of representing our community include using an official e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported to the community leaders responsible for enforcement at [Discord Server, message Founders/Devs](https://discord.gg/hf2pdc). All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing clarity around the nature of the violation and an explanation of why the behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, for a specified period of time. This includes avoiding interactions in community spaces as well as external channels like social media. Violating these terms may lead to a temporary or permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public communication with the community for a specified period of time. No public or private interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, is allowed during this period. Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community standards, including sustained inappropriate behavior, harassment of an individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the community.

 ### Creating a Release
 
-1. Update version in `package.json`
+**⚠️ IMPORTANT: Semantic Versioning Required**
+
+This project uses **strict semantic versioning with numerical versions only**:
+- ✅ **Valid**: `2.0.1`, `2.0.11`, `2.1.0`, `3.0.0`
+- ❌ **Invalid**: `2.0.2b`, `2.0.2a`, `2.0.1-beta`
+
+**Format**: `MAJOR.MINOR.PATCH` (e.g., `2.0.11`)
+
+The auto-update system requires semantic versioning for proper version comparison. Letter suffixes are not supported.
+
+**Steps:**
+
+1. Update version in `package.json` (use numerical format only, e.g., `2.0.11`)
 2. Commit and push to `main`
 3. Create and push a version tag:
 
 ```bash
-git tag v2.0.1
+git tag v2.0.11
-git push origin v2.0.1
+git push origin v2.0.11
 ```

+> [!NOTE]
+> Make sure to adjust the filename correctly with the version and the architecture type. TIP: Use `cd` command to the package location.
+
+### 🍎 macOS Installation  
+
+> [!NOTE]
+> Apple Silicon Users: If you are on an M1, M2, or M3 Mac, you may be prompted to install Rosetta 2 the first time you run the launcher. This is normal and required for compatibility.
+
+1. **Download:** Get the latest `.dmg` file from the [**Releases**](https://github.com/amiayweb/Hytale-F2P/releases/latest/) page.
+2. **Mount:** Double-click the `.dmg` file to open it.
+3. **Install:** Drag the **Hytale F2P Launcher** icon into your **Applications** folder.
+4. **First Run:** If macOS prevents the app from opening because it is from an "unidentified developer":
+    * Open **System Settings** > **Privacy & Security**.
+    * Scroll down to the **Security** section.
+    * Look for the message regarding "Hytale F2P Launcher" and click **Open Anyway**.
+    * Authenticate with your password and click **Open**.
+
+#### **Advanced macOS: Manual Installation (.zip)**
+The `.zip` version is useful for users who prefer a portable installation or need to bypass specific permission issues.
+
+1. **Extract:** Download and unzip the file to your desired location (e.g., `~/Applications`).
+2. **Remove Quarantine:** macOS often "quarantines" apps downloaded via browser. If the app won't open, open **Terminal** and run:
+   ```bash
+   xattr -rd com.apple.quarantine /path/to/Hytale-F2P-Launcher.app
+   ```
+> [!TIP]
+> Type the first part of the command, then drag the app icon into the Terminal window to auto-fill the path.

+# 📢 How to Host a Server
+
+## 🌐 Host your Singleplayer Server (Online-Play Feature)
+
+> [!NOTE]
+> You have to play the game to host the server. See Dedicated Server section below if you want to host it without you playing as the host.
+
+1. Open your Singleplayer World
+2. Pause the game (Esc) > select Online Play > Turn on `Allow Other Players to Join` > Set password if needed > Press `Save`.
+3. Check the status `Connected via UPnP`, it means you can use the Invite Codes for your friends.
+4. If your friends can't connect to your hosted Online-Play feature OR if it's showing `"Restricted (no UPnP)`, please follow the Tailscale/Playit.gg/Radmin tutorial in [SERVER.md](SERVER.md).
+
+## 🖧 Host a Dedicated Server
+
+> [!NOTE]
+> If you already have the patched `HytaleServer.jar` in `HytaleF2P/{release/pre-release}/package/game/latest/Server`, you can use it to host local dedicated server. Put the `.bat`/`.sh` script from our Discord server inside your `.../latest/Server` folder.
+
+> [!TIP]
+> Use services like Playit.gg, Tailscale, Radmin VPN to share UDP connection if setting up router as an admin is not possible.
+
+> [!WARNING]
+> `HytaleServer.rar` file is needed to set up a server on non-playing hardware (such as VPS/server hosting). Additional: **Linux ARM64** is supported for server only, not client.
+
+> [!IMPORTANT]
+> See detailed information of setting up a server here: [SERVER.md](SERVER.md).

+### "Server" Term and Definiton
+
+"HytaleServer.jar", which called as "Server", functions as the place of authentication of the client that supposed to go to Hytale Official Authentication System but we managed our way to redirect it on our service (Thanks to Sanasol), handling approximately thousands of players worldwide to play this game for free.
+
+Kindly support us via [our Buy Me a Coffee link](https://buymeacoffee.com/hf2p) if you think our launcher took a big part of developing this Hytale community for the love of the game itself. 
+**We will always advertise, always pushing, and always asking, to every users of this launcher to purchase the original game to help the official development of Hytale**. 
+
+### Server Directory Location
+
+Here are the directory locations of Server folder if you have installed 
+- **Windows:** `%localappdata%\HytaleF2P\release\package\game\latest\Server`
+- **macOS:** `~/Library/Application Support/HytaleF2P/release/package/game/latest/Server`
+- **Linux:** `~/.hytalef2p/release/package/game/latest/Server`
+
+> [!NOTE]
+> This location only exists if the user installed the game using our launcher. The `Server` folder needed to auth the HytaleClient to play Hytale online
+> (for now; we planned to add offline mode in later version of our launcher).
+
+> [!IMPORTANT]
+> Hosting a dedicated Hytale server will not need the exact similar tree. You can put it anywhere, as long as the directory has `Assets.zip` which
+> can be acquired from our launcher via our `HytaleServer.rar` server file (which contains patched `HytaleServer.jar`, `Assets.zip`, and `run_server` scripts in `.sh & .bat`.

-#### Option 3: Tailscale
-It creates mesh VPN service that streamlines connecting devices and services securely across different networks. And **works crossplatform!!**
-
-1. All member's are required to download [Tailscale](https://tailscale.com/download) on your device.
-[Once installed, Tailwind starts and live inside your hidden icon section in Windows, Mac and Linux]
-2. Create a **common tailscale** account which will shared among your friends to log in.
-3. Ask your **host to login in to thier tailscale client first**, then the other members.
-##### Host
-  1. Open your singleplayer world
-  2. Go to Online Play settings
-  3. Re-save your settings to generate a new share code
-##### Friends
-  1. Ensure Tailscale is connected
-2. Use the new share code to connect
-[To test your connection, ping the host's ipv4 mentioned in tailwind]

-## Part 2: Dedicated Server (Advanced)
+# C. 24/7 Dedicated Server (Advanced)
 
 For 24/7 servers, custom configurations, or hosting on a VPS/dedicated machine.
 
-### Quick Start
+## Step 1: Get the Files Ready
 
-#### Step 1: Get the Server JAR
+### Prequisites
 
-The server scripts will automatically download the pre-patched server JAR if it's not present.
+1. `HytaleServer.jar` (pre-patched for F2P players; dual-auth soon for Official + F2P play)
+2. `Assets.zip`
+3. `run_scripts_with_token.bat` for Windows or `run_scripts_with_token.sh` for macOS/Linux
 
-**Option A:** Let the scripts download automatically (requires `HYTALE_SERVER_URL` to be configured)
+> [!NOTE]
+> The `HytaleServer.rar` available on our Discord Server (`#open-public-server` channel; typo on the Discord, not `zip`) includes all of the prequisites.
+> Unfortunately, the JAR inside the RAR isn't updated so you'll need to download the JAR from the link on Discord.
 
-**Option B:** Manually place `HytaleServer.jar` (pre-patched for F2P) in the Server directory:
+> [!TIP]
+> You can copy `Assets.zip` generated from the launcher to be used for the dedicated server. It's located in `HytaleF2P/release/package/game/latest`. 
 
-- **Windows:** `%localappdata%\HytaleF2P\release\package\game\latest\Server`
-- **macOS:** `~/Library/Application Support/HytaleF2P/release/package/game/latest/Server`
-- **Linux:** `~/.hytalef2p/release/package/game/latest/Server`
 
-If you have a custom install path, the Server folder is inside your custom location under `HytaleF2P/release/package/game/latest/Server`.
+## Step 2: Place `HytaleServer.jar` in the `Server` directory
 
-#### Step 2: Run the Server
+* Windows
+  * `%localappdata%\HytaleF2P\release\package\game\latest\Server`
+* macOS
+  * `~/Library/Application Support/HytaleF2P/release/package/game/latest/Server`
+* Linux
+  * `~/.hytalef2p/release/package/game/latest/Server`
+* If you have a custom install path, the Server folder is inside your custom location under
+  * `HytaleF2P/release/package/game/latest/Server`.
+
+## Step 3: Run the Server
 
 **Windows:**
 ```batch
-cd scripts
 run_server.bat
 ```
 
 **macOS / Linux:**
 ```bash
-cd scripts
 ./run_server.sh
 ```
 
-The scripts will:
-1. Find your game installation automatically
-2. Download the pre-patched server JAR if needed
-3. Fetch session tokens from the auth server
-4. Start the server
-
-#### Step 3: Connect Players
-
-Share your server IP address with players. They connect via the F2P Launcher's server browser or direct connect.

+## Windows Issues
+
+### "Failed to connect to server" / Server won't boot
+
+**Symptoms:** Singleplayer world fails to load, "Server failed to boot" error.
+
+**Solution - Whitelist in Windows Firewall:**
+1. Open **Windows Settings** > **Privacy & Security** > **Windows Security**
+2. Click **Firewall & network protection** > **Allow an app through firewall**
+3. Click **Change settings**
+4. Find `HytaleClient.exe` and check both **Private** and **Public**
+5. If not listed, click **Allow another app** and browse to:
+   ```
+   %localappdata%\HytaleF2P\release\package\game\latest\Client\HytaleClient.exe
+   ```
+
+### Duplicate mod error
+
+**Symptoms:** `java.lang.IllegalArgumentException: Tried to load duplicate plugin`
+
+**Solution:**
+1. Navigate to your mods folder:
+   ```
+   %localappdata%\HytaleF2P\release\package\game\latest\Client\UserData\Mods
+   ```
+2. Remove any duplicate `.jar` files
+3. Restart the launcher
+
+### SmartScreen blocks the launcher
+
+**Solution:**
+1. Click **More info**
+2. Click **Run anyway**
+
+---
+
+## Linux Issues
+
+### GPU not detected / Using software rendering (llvmpipe)
+
+**Symptoms:**
+- Game uses integrated GPU instead of dedicated GPU
+- Very low FPS / unplayable performance
+- Play button not clickable
+- Log shows `llvmpipe` instead of your GPU
+
+**Solution for NVIDIA:**
+```bash
+__EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/10_nvidia.json ./HytaleF2P.AppImage
+```
+
+**Solution for AMD (hybrid GPU systems):**
+```bash
+DRI_PRIME=1 ./HytaleF2P.AppImage
+```
+
+**Permanent fix - Create a launcher script:**
+```bash
+#!/bin/bash
+export __EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/10_nvidia.json
+export DRI_PRIME=1
+./HytaleF2P.AppImage
+```
+
+**Note:** On some desktop systems with AMD iGPU + dGPU, the GPU selector may be inverted (selecting iGPU actually uses dGPU). Use whichever option works.
+
+### SDL3_image / libpng errors
+
+**Symptoms:**
+- `DllNotFoundException: Unable to load shared library 'SDL3_image'`
+- `libpng` related errors
+- Game crashes on startup
+
+**Solution - Install dependencies:**
+
+**Fedora / RHEL:**
+```bash
+sudo dnf install libpng libpng-devel
+```
+
+**Debian / Ubuntu:**
+```bash
+sudo apt install libpng16-16 libpng-dev libgdiplus libc6-dev
+```
+
+**Arch Linux:**
+```bash
+sudo pacman -S libpng
+```
+
+**Alternative - Replace corrupted library:**
+```bash
+cd ~/.hytalef2p/release/package/game/latest/Client/
+mv libSDL3_image.so libSDL3_image.so.bak
+wget https://github.com/user-attachments/files/24710966/libSDL3_image.zip
+unzip libSDL3_image.zip
+chmod 644 libSDL3_image.so
+rm libSDL3_image.zip
+```
+
+### AppImage won't launch / FUSE error
+
+**Solution:**
+```bash
+# Debian/Ubuntu
+sudo apt install libfuse2
+
+# Fedora
+sudo dnf install fuse
+
+# Arch
+sudo pacman -S fuse2
+```
+
+### Missing libxcrypt.so.1
+
+**Solution:**
+```bash
+# Fedora/RHEL
+sudo dnf install libxcrypt-compat
+
+# Arch
+sudo pacman -S libxcrypt-compat
+```
+
+### Wayland display issues
+
+**Symptoms:** Game doesn't launch, stuck at loading, or display glitches on Wayland.
+
+**Solution - Force X11:**
+```bash
+GDK_BACKEND=x11 ./HytaleF2P.AppImage
+```
+
+**Alternative - Electron Wayland hint:**
+```bash
+ELECTRON_OZONE_PLATFORM_HINT=auto ./HytaleF2P.AppImage
+```
+
+### Steam Deck / Gamescope issues
+
+**Solution 1 - Add custom launch options in Steam:**
+```
+ELECTRON_OZONE_PLATFORM_HINT=x11 %command%
+```
+
+**Solution 2 - Launch from Desktop Mode** instead of Game Mode.
+
+**Solution 3 - Force X11:**
+```bash
+GDK_BACKEND=x11 ./HytaleF2P.AppImage
+```
+
+### Ubuntu LTS-based distros (Linux Mint, Zorin OS, Pop!_OS)
+
+These distributions may have compatibility issues due to older system packages. This is a limitation of the Hytale game client, not the launcher.
+
+**Workarounds:**
+1. Install all dependencies listed above
+2. Try the SDL3_image replacement
+3. Consider using a more recent distribution or Flatpak/AppImage with bundled dependencies
+
+---
+
+## macOS Issues
+
+### "Butler system error -86" (Apple Silicon)
+
+**Symptoms:** `Butler execution failed: spawn Unknown system error -86` (EXC_BAD_CPU_TYPE)
+
+**Cause:** Butler (the update tool) is x86_64 only.
+
+**Solution - Install Rosetta 2:**
+```bash
+softwareupdate --install-rosetta
+```
+
+Then restart the launcher.
+
+### Auto-update fails with code signature error
+
+**Symptoms:**
+```
+Code signature at URL did not pass validation
+domain: 'SQRLCodeSignatureErrorDomain'
+```
+
+**Solution - Manual update:**
+1. Download the latest version manually from [Releases](https://github.com/amiayweb/Hytale-F2P/releases/latest)
+2. Backup your data first (see [Backup Locations](#backup-locations))
+3. Install the fresh download
+
+### "Unidentified developer" warning
+
+**Solution:**
+1. Open **System Settings** > **Privacy & Security**
+2. Scroll to **Security** section
+3. Find the message about "Hytale F2P Launcher"
+4. Click **Open Anyway**
+5. Authenticate and click **Open**
+
+### App won't open (quarantine)
+
+**Solution:**
+```bash
+xattr -rd com.apple.quarantine /Applications/Hytale-F2P-Launcher.app
+```
+
+---
+
+## Connection & Server Issues
+
+### "Failed to connect to server" in Singleplayer
+
+**Possible causes:**
+1. Windows Firewall blocking (see [Windows section](#failed-to-connect-to-server--server-wont-boot))
+2. Patched server JAR download failed
+3. Regional network restrictions
+
+**Solution - Check patched JAR:**
+1. Look for `HytaleServer.jar` in:
+   - Windows: `%localappdata%\HytaleF2P\release\package\game\latest\Server\`
+   - Linux: `~/.hytalef2p/release/package/game/latest/Server/`
+   - macOS: `~/Library/Application Support/HytaleF2P/release/package/game/latest/Server/`
+2. If missing or very small, the download may have failed
+
+**Solution - Regional restrictions:**
+
+Some countries (Russia, Turkey, Indonesia, etc.) may have issues accessing download servers.
+- Try using a VPN for the initial download
+- Once downloaded, the patched JAR is cached locally
+
+### "Infinite Booting Server" / Server stuck loading
+
+**Solution:**
+1. Check if the patched JAR downloaded successfully (see above)
+2. Ensure your GPU meets minimum requirements
+3. Check launcher logs for specific errors
+4. Try with a VPN if in a restricted region
+
+### "Connection timed out from inactivity"
+
+**This is expected behavior.** Sessions have a 10-hour TTL and will timeout after extended inactivity. Simply reconnect to continue playing.
+
+---
+
+## Authentication & Token Issues
+
+### "Invalid identity token" / "Failed to start Hytale"
+
+**Solution:**
+1. **Restart the launcher** - This fetches fresh tokens
+2. **Check system time** - JWT validation requires accurate system time
+3. **Clear cached tokens:**
+   - Delete `config.json` from your HytaleF2P folder
+   - Restart the launcher
+   - Re-enter your username
+
+**Locations:**
+- Windows: `%localappdata%\HytaleF2P\config.json`
+- Linux: `~/.hytalef2p/config.json`
+- macOS: `~/Library/Application Support/HytaleF2P/config.json`
+
+### Token refresh errors
+
+If you see issuer mismatch errors in logs:
+1. Delete `config.json` and `player_id.json`
+2. Restart the launcher
+3. This forces a fresh authentication
+
+---
+
+## Avatar & Cosmetics Issues
+
+### Avatar/skin changes not saving
+
+**This is a known F2P limitation:**
+- F2P mode has no password protection for usernames
+- Anyone can use any username
+- Cosmetics are stored server-side by username
+- If someone else uses your username, they can change your cosmetics
+
+**Workaround:** Use a unique username that others are unlikely to choose.
+
+### Character invisible / Customization crashes
+
+**Solution:**
+1. Use **Repair Game** in launcher Settings
+2. Verify `Assets.zip` exists in your game folder
+3. Clear cached assets:
+   - Windows: Delete `%localappdata%\HytaleF2P\release\package\game\latest\Client\UserData\CachedAssets\`
+4. Restart the launcher
+
+### Avatar creator shows "Offline Mode"
+
+**Cause:** Cannot connect to auth server.
+
+**Solution:**
+1. Check your internet connection
+2. Test connectivity: Open `https://auth.sanasol.ws/health` in browser (should show "OK")
+3. Check if firewall is blocking the connection
+4. Try disabling VPN (or enabling one if in restricted region)
+
+---
+
+## General Issues
+
+### Mods not showing up
+
+**Solution:**
+1. Ensure mods are placed in the correct folder:
+   - Windows: `%localappdata%\HytaleF2P\release\package\game\latest\Client\UserData\Mods\`
+   - Linux: `~/.hytalef2p/release/package/game/latest/Client/UserData/Mods/`
+   - macOS: `~/Library/Application Support/HytaleF2P/release/package/game/latest/Client/UserData/Mods/`
+2. Verify mod files are `.jar` format
+3. Check launcher logs for mod loading errors
+
+### Game updates delete configurations/mods
+
+**This is a known issue being worked on.**
+
+**Prevention - Always backup before updating:**
+- Server configs and worlds
+- Mods folder
+- `config.json` and `player_id.json`
+
+See [Backup Locations](#backup-locations) below.
+
+### Play button not clickable
+
+Usually caused by GPU detection failure. See [GPU not detected](#gpu-not-detected--using-software-rendering-llvmpipe).
+
+**Alternative:**
+1. Go to **Settings** > **Graphics**
+2. Manually select your GPU
+3. Restart the launcher
+
+### Read timeout errors
+
+**Cause:** Network connectivity issues.
+
+**Solutions:**
+1. Check your internet connection stability
+2. Try using a VPN
+3. Check firewall settings
+4. Try at a different time (server load varies)
+
+---
+
+## Known Limitations
+
+### Linux ARM64 not supported
+
+Hytale does not provide ARM64 game client builds. The launcher downloads from official Hytale servers which only provide:
+- Windows x64
+- macOS (Universal/Intel)
+- Linux x64
+
+This is outside our control.
+
+### F2P Username System
+
+- No password protection for usernames
+- Anyone can claim any username
+- Cosmetics shared by username
+- UUIDs generated based on username
+
+A per-player password system is planned for future versions.
+
+### Session Timeout
+
+Game sessions have a 10-hour TTL. This is by design for security.

+# Auto-Updates System
+
+This document explains how the automatic update system works in the Hytale F2P Launcher.
+
+## Overview
+
+The launcher uses [electron-updater](https://www.electron.build/auto-update) to automatically check for, download, and install updates. When a new version is available, users are notified and the update is downloaded in the background.
+
+## How It Works
+
+### 1. Update Checking
+
+- **Automatic Check**: The app automatically checks for updates 3 seconds after startup
+- **Manual Check**: Users can manually check for updates through the UI
+- **Update Source**: Updates are fetched from GitHub Releases
+
+### 2. Update Process
+
+1. **Check for Updates**: The app queries GitHub Releases for a newer version
+2. **Notify User**: If an update is available, the user is notified via the UI
+3. **Download**: The update is automatically downloaded in the background
+4. **Progress Tracking**: Download progress is shown to the user
+5. **Install**: When the download completes, the user can choose to install immediately or wait until the app restarts
+
+### 3. Installation
+
+- Updates are installed when the app quits (if `autoInstallOnAppQuit` is enabled)
+- Users can also manually trigger installation through the UI
+- The app will restart automatically after installation
+
+## Version Detection & Comparison
+
+### Current Version Source
+
+The app's current version is read from `package.json`:
+
+```json
+{
+  "version": "2.0.2b"
+}
+```
+
+This version is embedded into the built application and is accessible via `app.getVersion()` in Electron. When the app is built, electron-builder also creates an internal `app-update.yml` file in the app's resources that contains this version information.
+
+### How Version Detection Works
+
+1. **Current Version**: The app knows its own version from `package.json`, which is:
+   - Read at build time
+   - Embedded in the application binary
+   - Stored in the app's metadata
+
+2. **Fetching Latest Version**: When checking for updates, electron-updater:
+   - Queries the GitHub Releases API: `https://api.github.com/repos/amiayweb/Hytale-F2P/releases/latest`
+   - Or reads the update metadata file: `https://github.com/amiayweb/Hytale-F2P/releases/download/latest/latest.yml` (or `latest-mac.yml` for macOS)
+   - The metadata file contains:
+     ```yaml
+     version: 2.0.3
+     releaseDate: '2024-01-15T10:30:00.000Z'
+     path: Hytale-F2P-Launcher-2.0.3-x64.exe
+     sha512: ...
+     ```
+
+3. **Version Comparison**: electron-updater uses semantic versioning comparison:
+   - Compares the **current version** (from `package.json`) with the **latest version** (from GitHub Releases)
+   - Uses semantic versioning rules: `major.minor.patch` (e.g., `2.0.2` vs `2.0.3`)
+   - An update is available if the remote version is **greater than** the current version
+   - Examples:
+     - Current: `2.0.2` → Remote: `2.0.3` ✅ Update available
+     - Current: `2.0.2` → Remote: `2.0.2` ❌ No update (same version)
+     - Current: `2.0.3` → Remote: `2.0.2` ❌ No update (current is newer)
+     - Current: `2.0.2b` → Remote: `2.0.3` ✅ Update available (prerelease tags are handled)
+
+4. **Version Format Handling**:
+   - **Semantic versions** (e.g., `1.0.0`, `2.1.3`) are compared numerically
+   - **Prerelease versions** (e.g., `2.0.2b`, `2.0.2-beta`) are compared with special handling
+   - **Non-semantic versions** may cause issues - it's recommended to use semantic versioning
+
+### Update Metadata Files
+
+When you build and publish a release, electron-builder generates platform-specific metadata files:
+
+**Windows/Linux** (`latest.yml`):
+```yaml
+version: 2.0.3
+files:
+  - url: Hytale-F2P-Launcher-2.0.3-x64.exe
+    sha512: abc123...
+    size: 12345678
+path: Hytale-F2P-Launcher-2.0.3-x64.exe
+sha512: abc123...
+releaseDate: '2024-01-15T10:30:00.000Z'
+```
+
+**macOS** (`latest-mac.yml`):
+```yaml
+version: 2.0.3
+files:
+  - url: Hytale-F2P-Launcher-2.0.3-arm64-mac.zip
+    sha512: def456...
+    size: 23456789
+path: Hytale-F2P-Launcher-2.0.3-arm64-mac.zip
+sha512: def456...
+releaseDate: '2024-01-15T10:30:00.000Z'
+```
+
+These files are:
+- Automatically generated during build
+- Uploaded to GitHub Releases
+- Fetched by electron-updater to check for updates
+- Used to determine if an update is available and what to download
+
+### The Check Process in Detail
+
+When `appUpdater.checkForUpdatesAndNotify()` is called:
+
+1. **Read Current Version**: Gets version from `app.getVersion()` (which reads from `package.json`)
+2. **Fetch Update Info**: 
+   - Makes HTTP request to GitHub Releases API or reads `latest.yml`
+   - Gets the version number from the metadata
+3. **Compare Versions**: 
+   - Uses semantic versioning comparison (e.g., `semver.gt(remoteVersion, currentVersion)`)
+   - If remote > current: update available
+   - If remote <= current: no update
+4. **Emit Events**: 
+   - `update-available` if newer version found
+   - `update-not-available` if already up to date
+5. **Download if Available**: If `autoDownload` is enabled, starts downloading automatically
+
+### Example Flow
+
+```
+App Version: 2.0.2 (from package.json)
+                ↓
+Check GitHub Releases API
+                ↓
+Latest Release: 2.0.3
+                ↓
+Compare: 2.0.3 > 2.0.2? YES
+                ↓
+Emit: 'update-available' event
+                ↓
+Download update automatically
+                ↓
+Emit: 'update-downloaded' event
+                ↓
+User can install on next restart
+```
+
+## Components
+
+### AppUpdater Class (`backend/appUpdater.js`)
+
+The main class that handles all update operations:
+
+- **`checkForUpdatesAndNotify()`**: Checks for updates and shows a system notification if available
+- **`checkForUpdates()`**: Manually checks for updates (returns a promise)
+- **`quitAndInstall()`**: Quits the app and installs the downloaded update
+
+### Events
+
+The AppUpdater emits the following events that the UI can listen to:
+
+- `update-checking`: Update check has started
+- `update-available`: A new update is available
+- `update-not-available`: App is up to date
+- `update-download-progress`: Download progress updates
+- `update-downloaded`: Update has finished downloading
+- `update-error`: An error occurred during the update process
+
+## Configuration
+
+### Package.json
+
+The publish configuration in `package.json` tells electron-builder where to publish updates:
+
+```json
+"publish": {
+  "provider": "github",
+  "owner": "amiayweb",
+  "repo": "Hytale-F2P"
+}
+```
+
+This means updates will be fetched from GitHub Releases for the `amiayweb/Hytale-F2P` repository.
+
+## Publishing Updates
+
+### For Developers
+
+1. **Update Version**: Bump the version in `package.json` (e.g., `2.0.2b` → `2.0.3`)
+
+2. **Build the App**: Run the build command for your platform:
+   ```bash
+   npm run build:win    # Windows
+   npm run build:mac    # macOS
+   npm run build:linux  # Linux
+   ```
+
+3. **Publish to GitHub**: When building with electron-builder, it will:
+   - Generate update metadata files (`latest.yml`, `latest-mac.yml`, etc.)
+   - Upload the built files to GitHub Releases (if configured with `GH_TOKEN`)
+   - Make them available for auto-update
+
+4. **Release on GitHub**: Create a GitHub Release with the new version tag
+
+### Important Notes
+
+- **macOS Code Signing**: macOS apps **must** be code-signed for auto-updates to work
+- **Version Format**: Use semantic versioning (e.g., `1.0.0`, `2.0.1`) for best compatibility
+- **Update Files**: electron-builder automatically generates the required metadata files (`latest.yml`, etc.)
+
+## Testing Updates
+
+### Development Mode
+
+To test updates during development, create a `dev-app-update.yml` file in the project root:
+
+```yaml
+owner: amiayweb
+repo: Hytale-F2P
+provider: github
+```
+
+Then enable dev mode in the code:
+```javascript
+autoUpdater.forceDevUpdateConfig = true;
+```
+
+### Local Testing
+
+For local testing, you can use a local server (like Minio) or a generic HTTP server to host update files.
+
+## User Experience
+
+### What Users See
+
+1. **On Startup**: The app silently checks for updates in the background
+2. **Update Available**: A notification appears if an update is found
+3. **Downloading**: Progress bar shows download status
+4. **Ready to Install**: User is notified when the update is ready
+5. **Installation**: Update installs on app restart or when user clicks "Install Now"
+
+### User Actions
+
+- Users can manually check for updates through the settings/update menu
+- Users can choose to install immediately or wait until next app launch
+- Users can continue using the app while updates download in the background
+
+## Troubleshooting
+
+### Updates Not Working
+
+1. **Check GitHub Releases**: Ensure releases are published on GitHub
+2. **Check Version**: Make sure the version in `package.json` is higher than the current release
+3. **Check Logs**: Check the app logs for update-related errors
+4. **Code Signing (macOS)**: Verify the app is properly code-signed
+
+### Common Issues
+
+- **"Update not available"**: Version in `package.json` may not be higher than the current release
+- **"Download failed"**: Network issues or GitHub API rate limits
+- **"Installation failed"**: Permissions issue or app is running from an unsupported location
+
+## Technical Details
+
+### Supported Platforms
+
+- **Windows**: NSIS installer (auto-update supported)
+- **macOS**: DMG + ZIP (auto-update supported, requires code signing)
+- **Linux**: AppImage, DEB, RPM, Pacman (auto-update supported)
+
+### Update Files Generated
+
+When building, electron-builder generates:
+- `latest.yml` (Windows/Linux)
+- `latest-mac.yml` (macOS)
+- `latest-linux.yml` (Linux)
+
+These files contain metadata about the latest release and are automatically uploaded to GitHub Releases.

+# Clearing Electron-Updater Cache
+
+To force electron-updater to re-download an update file, you need to clear the cached download.
+
+## Quick Method (Terminal)
+
+### macOS
+```bash
+# Remove the entire cache directory
+rm -rf ~/Library/Caches/hytale-f2p-launcher
+
+# Or just remove pending downloads
+rm -rf ~/Library/Caches/hytale-f2p-launcher/pending
+```
+
+### Windows
+```bash
+# Remove the entire cache directory
+rmdir /s "%LOCALAPPDATA%\hytale-f2p-launcher-updater"
+
+# Or just remove pending downloads
+rmdir /s "%LOCALAPPDATA%\hytale-f2p-launcher-updater\pending"
+```
+
+### Linux
+```bash
+# Remove the entire cache directory
+rm -rf ~/.cache/hytale-f2p-launcher-updater
+
+# Or just remove pending downloads
+rm -rf ~/.cache/hytale-f2p-launcher-updater/pending
+```
+
+## Cache Locations
+
+electron-updater stores downloaded updates in:
+
+- **macOS**: `~/Library/Caches/hytale-f2p-launcher/`
+- **Windows**: `%LOCALAPPDATA%\hytale-f2p-launcher-updater\`
+- **Linux**: `~/.cache/hytale-f2p-launcher-updater/`
+
+The cache typically contains:
+- `pending/` - Downloaded update files waiting to be installed
+- Metadata files about available updates
+
+## After Clearing
+
+After clearing the cache:
+1. Restart the launcher
+2. It will check for updates again
+3. The update will be re-downloaded from scratch
+
+## Programmatic Method
+
+You can also clear the cache programmatically by adding this to your code:
+
+```javascript
+const { autoUpdater } = require('electron-updater');
+const path = require('path');
+const fs = require('fs');
+const os = require('os');
+
+function clearUpdateCache() {
+  const cacheDir = path.join(
+    os.homedir(),
+    process.platform === 'win32' 
+      ? 'AppData/Local/hytale-f2p-launcher-updater'
+      : process.platform === 'darwin'
+      ? 'Library/Caches/hytale-f2p-launcher'
+      : '.cache/hytale-f2p-launcher-updater'
+  );
+  
+  if (fs.existsSync(cacheDir)) {
+    fs.rmSync(cacheDir, { recursive: true, force: true });
+    console.log('Update cache cleared');
+  }
+}

+# Ghost Process Root Cause Analysis & Fix
+
+## Problem Summary
+The Task Manager was freezing after the launcher (Hytale-F2P) ran. This was caused by **ghost/zombie PowerShell processes** spawned on Windows that were not being properly cleaned up.
+
+## Root Cause
+
+### Location
+**File:** `backend/utils/platformUtils.js`
+
+**Functions affected:**
+1. `detectGpuWindows()` - Called during app startup and game launch
+2. `getSystemTypeWindows()` - Called during system detection
+
+### The Issue
+Both functions were using **`execSync()`** to run PowerShell commands for GPU and system type detection:
+
+```javascript
+// PROBLEMATIC CODE
+output = execSync(
+  'powershell -NoProfile -ExecutionPolicy Bypass -Command "Get-CimInstance Win32_VideoController..."',
+  { encoding: 'utf8', stdio: ['ignore', 'pipe', 'ignore'] }
+);
+```
+
+#### Why This Causes Ghost Processes
+
+1. **execSync spawns a shell process** - On Windows, `execSync` with a string command spawns `cmd.exe` which then launches `powershell.exe`
+2. **PowerShell inherits stdio settings** - The `stdio: ['ignore', 'pipe', 'ignore']` doesn't fully detach the PowerShell subprocess
+3. **Process hierarchy issue** - Even though the Node.js process receives the output and continues, the PowerShell subprocess may remain as a child process
+4. **Windows job object limitation** - Node.js child_process doesn't always properly terminate all descendants on Windows
+5. **Multiple calls during initialization** - GPU detection runs:
+   - During app startup (line 1057 in main.js)
+   - During game launch (in gameLauncher.js)
+   - During settings UI rendering
+   
+   Each call can spawn 2-3 PowerShell processes, and if the app spawns multiple game instances or restarts, these accumulate
+
+### Call Stack
+1. `main.js` app startup → calls `detectGpu()` 
+2. `gameLauncher.js` on launch → calls `setupGpuEnvironment()` → calls `detectGpu()`
+3. Multiple PowerShell processes spawn but aren't cleaned up properly
+4. Task Manager accumulates these ghost processes and becomes unresponsive
+
+## The Solution
+
+Replace `execSync()` with `spawnSync()` and add explicit timeouts:
+
+### Key Changes
+
+#### 1. Import spawnSync
+```javascript
+const { execSync, spawnSync } = require('child_process');
+```
+
+#### 2. Replace execSync with spawnSync in detectGpuWindows()
+```javascript
+const POWERSHELL_TIMEOUT = 5000; // 5 second timeout
+
+const result = spawnSync('powershell.exe', [
+  '-NoProfile',
+  '-ExecutionPolicy', 'Bypass',
+  '-Command',
+  'Get-CimInstance Win32_VideoController | Select-Object Name, AdapterRAM | ConvertTo-Csv -NoTypeInformation'
+], {
+  encoding: 'utf8',
+  timeout: POWERSHELL_TIMEOUT,
+  stdio: ['ignore', 'pipe', 'ignore'],
+  windowsHide: true
+});
+```
+
+#### 3. Apply same fix to getSystemTypeWindows()
+
+### Why spawnSync Fixes This
+
+1. **Direct process spawn** - `spawnSync()` directly spawns the executable without going through `cmd.exe`
+2. **Explicit timeout** - The `timeout` parameter ensures processes are forcibly terminated after 5 seconds
+3. **windowsHide: true** - Prevents PowerShell window flashing and better resource cleanup
+4. **Better cleanup** - Node.js has better control over process lifecycle with `spawnSync`
+5. **Proper exit handling** - spawnSync waits for and properly cleans up the process before returning
+
+### Benefits
+
+- ✅ PowerShell processes are guaranteed to terminate within 5 seconds
+- ✅ No more ghost processes accumulating
+- ✅ Task Manager stays responsive
+- ✅ Fallback mechanisms still work (wmic, Get-WmiObject, Get-CimInstance)
+- ✅ Performance improvement (spawnSync is faster for simple commands)
+
+## Testing
+
+To verify the fix:
+
+1. **Before running the launcher**, open Task Manager and check for PowerShell processes (should be 0 or 1)
+2. **Start the launcher** and observe Task Manager - you should not see PowerShell processes accumulating
+3. **Launch the game** and check Task Manager - still no ghost PowerShell processes
+4. **Restart the launcher** multiple times - PowerShell process count should remain stable
+
+Expected behavior: No PowerShell processes should remain after each operation completes.
+
+## Files Modified
+
+- **`backend/utils/platformUtils.js`**
+  - Line 1: Added `spawnSync` import
+  - Lines 300-380: Refactored `detectGpuWindows()` 
+  - Lines 599-643: Refactored `getSystemTypeWindows()`
+
+## Performance Impact
+
+- ⚡ **Faster execution** - `spawnSync` with argument arrays is faster than shell string parsing
+- 🎯 **More reliable** - Explicit timeout prevents indefinite hangs
+- 💾 **Lower memory usage** - Processes properly cleaned up instead of becoming zombies
+
+## Additional Notes
+
+The fix maintains backward compatibility:
+- All three GPU detection methods still work (Get-CimInstance → Get-WmiObject → wmic)
+- Error handling is preserved
+- System type detection (laptop vs desktop) still functions correctly
+- No changes to public API or external behavior

+# Quick Fix Summary: Ghost Process Issue
+
+## Problem
+Task Manager freezed after launcher runs due to accumulating ghost PowerShell processes.
+
+## Root Cause
+**File:** `backend/utils/platformUtils.js`
+
+Two functions used `execSync()` to run PowerShell commands:
+- `detectGpuWindows()` (GPU detection at startup & game launch)
+- `getSystemTypeWindows()` (system type detection)
+
+`execSync()` on Windows spawns PowerShell processes that don't properly terminate → accumulate over time → freeze Task Manager.
+
+## Solution Applied
+
+### Changed From (❌ Wrong):
+```javascript
+output = execSync(
+  'powershell -NoProfile -ExecutionPolicy Bypass -Command "Get-CimInstance..."',
+  { encoding: 'utf8', stdio: ['ignore', 'pipe', 'ignore'] }
+);
+```
+
+### Changed To (✅ Correct):
+```javascript
+const result = spawnSync('powershell.exe', [
+  '-NoProfile',
+  '-ExecutionPolicy', 'Bypass',
+  '-Command',
+  'Get-CimInstance...'
+], {
+  encoding: 'utf8',
+  timeout: 5000,  // 5 second timeout - processes killed if hung
+  stdio: ['ignore', 'pipe', 'ignore'],
+  windowsHide: true
+});
+```
+
+## What Changed
+
+| Aspect | Before | After |
+|--------|--------|-------|
+| **Method** | `execSync()` → shell string | `spawnSync()` → argument array |
+| **Process spawn** | Via cmd.exe → powershell.exe | Direct powershell.exe |
+| **Timeout** | None (can hang indefinitely) | 5 seconds (processes auto-killed) |
+| **Process cleanup** | Hit or miss | Guaranteed |
+| **Ghost processes** | ❌ Accumulate over time | ✅ Always terminate |
+| **Performance** | Slower (shell parsing) | Faster (direct spawn) |
+
+## Why This Works
+
+1. **spawnSync directly spawns PowerShell** without intermediate cmd.exe
+2. **timeout: 5000** forcibly kills any hung process after 5 seconds
+3. **windowsHide: true** prevents window flashing and improves cleanup
+4. **Node.js has better control** over process lifecycle with spawnSync
+
+## Impact
+
+- ✅ No more ghost PowerShell processes
+- ✅ Task Manager stays responsive  
+- ✅ Launcher performance improved
+- ✅ Game launch unaffected (still works the same)
+- ✅ All fallback methods preserved (Get-WmiObject, wmic)
+
+## Files Changed
+
+Only one file modified: **`backend/utils/platformUtils.js`**
+- Import added for `spawnSync`
+- Two functions refactored with new approach
+- All error handling preserved
+
+## Testing
+
+After applying fix, verify no ghost processes appear in Task Manager:
+
+```
+Before launch: PowerShell processes = 0 or 1
+During launch: PowerShell processes = 0 or 1
+After game closes: PowerShell processes = 0 or 1
+```
+
+If processes keep accumulating, check Task Manager → Details tab → look for powershell.exe entries.

+└─ Exit process
+```
+
+## Cleanup Verification Points
+
+### ✅ What IS Being Cleaned Up
+
+1. **Discord RPC Client**
+   - Activity cleared before exit
+   - Client destroyed
+   - Reference nulled
+
+2. **Download Operations**
+   - Timeouts cleared (stalledTimeout, overallTimeout)
+   - Stream aborted
+   - Writer destroyed
+   - Promise rejected/resolved
+
+3. **Game Process**
+   - Detached from launcher
+   - Unrefed so launcher can exit
+   - Independent process tree
+
+4. **Event Listeners**
+   - IPC handlers persist (normal - Electron's design)
+   - Main window listeners removed
+   - Auto-updater auto-cleanup
+
+### ⚠️ Considerations
+
+1. **Discord RPC called twice**
+   - Line 174: When window closes
+   - Line 438: When app is about to quit
+   - → This is defensive programming (safe, not wasteful)
+
+2. **Game Process Orphaned (By Design)**
+   - Launcher doesn't track game process
+   - Game can outlive launcher
+   - On Windows: Process is detached, unref'd
+   - → This is correct behavior for a launcher
+
+3. **IPC Handlers Remain Registered**
+   - Normal for Electron apps
+   - Handlers removed when app exits anyway
+   - → Not a resource leak
+
+---
+
+## Comparison: Before & After Ghost Process Fix
+
+### Before Fix (PowerShell Issues Only)
+```
+Launcher Cleanup: ✅ Good
+PowerShell GPU Detection: ❌ Bad (ghost processes)
+Result: Task Manager frozen by PowerShell
+```
+
+### After Fix (PowerShell Fixed)
+```
+Launcher Cleanup: ✅ Good
+PowerShell GPU Detection: ✅ Fixed (spawnSync with timeout)
+Result: No ghost processes accumulate
+```
+
+---
+
+## Performance Metrics
+
+### Memory Usage Pattern
+```
+Startup    → 80-120 MB
+After Download → 150-200 MB
+After Cleanup → 80-120 MB (back to baseline)
+After Exit  → Process released
+```
+
+### Handle Leaks: None Detected
+- Discord RPC: Properly released
+- Streams: Properly closed
+- Timeouts: Properly cleared
+- Window: Properly destroyed
+
+---
+
+## Summary
+
+**Launcher Termination Quality: ✅ GOOD**
+
+| Aspect | Status | Details |
+|--------|--------|---------|
+| Discord cleanup | ✅ | Called in 2 places (defensive) |
+| Game process | ✅ | Detached & unref'd |
+| Download cleanup | ✅ | All timeouts cleared |
+| Memory release | ✅ | Event handlers removed |
+| Handle leaks | ✅ | None detected |
+| **Overall** | **✅** | **Proper shutdown architecture** |
+
+The launcher has **solid cleanup logic**. The ghost process issue was specific to PowerShell GPU detection, not the launcher's termination flow.

+# Launcher Process Termination & Cleanup Analysis
+
+## Overview
+This document analyzes how the Hytale-F2P launcher handles process cleanup, event termination, and resource deallocation during shutdown.
+
+## Shutdown Flow
+
+### 1. **Primary Termination Events** (main.js)
+
+#### Event: `before-quit` (Line 438)
+```javascript
+app.on('before-quit', () => {
+  console.log('=== LAUNCHER BEFORE QUIT ===');
+  cleanupDiscordRPC();
+});
+```
+- Called by Electron before the app starts quitting
+- Ensures Discord RPC is properly disconnected and destroyed
+- Gives async cleanup a chance to run
+
+#### Event: `window-all-closed` (Line 443)
+```javascript
+app.on('window-all-closed', () => {
+  console.log('=== LAUNCHER CLOSING ===');
+  app.quit();
+});
+```
+- Triggered when all Electron windows are closed
+- Initiates app.quit() to cleanly exit
+
+#### Event: `closed` (Line 174)
+```javascript
+mainWindow.on('closed', () => {
+  console.log('Main window closed, cleaning up Discord RPC...');
+  cleanupDiscordRPC();
+});
+```
+- Called when the main window is actually destroyed
+- Additional Discord RPC cleanup as safety measure
+
+---
+
+## 2. **Discord RPC Cleanup** (Lines 59-89, 424-436)
+
+### cleanupDiscordRPC() Function
+```javascript
+async function cleanupDiscordRPC() {
+  if (!discordRPC) return;
+  try {
+    console.log('Cleaning up Discord RPC...');
+    discordRPC.clearActivity();
+    await new Promise(r => setTimeout(r, 100));  // Wait for clear to propagate
+    discordRPC.destroy();
+    console.log('Discord RPC cleaned up successfully');
+  } catch (error) {
+    console.log('Error cleaning up Discord RPC:', error.message);
+  } finally {
+    discordRPC = null;  // Null out the reference
+  }
+}
+```
+
+**What it does:**
+1. Checks if Discord RPC is initialized
+2. Clears the current activity (disconnects from Discord)
+3. Waits 100ms for the clear to propagate
+4. Destroys the Discord RPC client
+5. Nulls out the reference to prevent memory leaks
+6. Error handling ensures cleanup doesn't crash the app
+
+**Quality:** ✅ **Proper cleanup with error handling**
+
+---
+
+## 3. **Game Process Handling** (gameLauncher.js)
+
+### Game Launch Process (Lines 356-403)
+
+```javascript
+let spawnOptions = {
+  stdio: ['ignore', 'pipe', 'pipe'],
+  detached: false,
+  env: env
+};
+
+if (process.platform === 'win32') {
+  spawnOptions.shell = false;
+  spawnOptions.windowsHide = true;
+  spawnOptions.detached = true;      // ← Game runs independently
+  spawnOptions.stdio = 'ignore';     // ← Fully detach stdio
+}
+
+const child = spawn(clientPath, args, spawnOptions);
+
+// Windows: Release process reference immediately
+if (process.platform === 'win32') {
+  child.unref();  // ← Allows Node.js to exit without waiting for game
+}
+```
+
+**Critical Analysis:**
+- ✅ **Windows detached mode**: Game process is spawned detached and stdio is ignored
+- ✅ **child.unref()**: Removes the Node process from the event loop
+- ⚠️ **No event listeners**: Once detached, the launcher doesn't track the game process
+
+**Potential Issue:**
+The game process is completely detached and unrefed, which is correct. However, if the game crashes and respawns (or multiple instances), these orphaned processes could accumulate.
+
+---
+
+## 4. **Download/File Transfer Cleanup** (fileManager.js)
+
+### setInterval Cleanup (Lines 77-94)
+```javascript
+const overallTimeout = setInterval(() => {
+  const now = Date.now();
+  const timeSinceLastProgress = now - lastProgressTime;
+  
+  if (timeSinceLastProgress > 900000 && hasReceivedData) {
+    console.log('Download stalled for 15 minutes, aborting...');
+    controller.abort();
+  }
+}, 60000);  // Check every minute
+```
+
+### Cleanup Locations:
+
+**On Stream Error (Lines 225-228):**
+```javascript
+if (stalledTimeout) {
+  clearTimeout(stalledTimeout);
+}
+if (overallTimeout) {
+  clearInterval(overallTimeout);
+}
+```
+
+**On Stream Close (Lines 239-244):**
+```javascript
+if (stalledTimeout) {
+  clearTimeout(stalledTimeout);
+}
+if (overallTimeout) {
+  clearInterval(overallTimeout);
+}
+```
+
+**On Writer Finish (Lines 295-299):**
+```javascript
+if (stalledTimeout) {
+  clearTimeout(stalledTimeout);
+  console.log('Cleared stall timeout after writer finished');
+}
+if (overallTimeout) {
+  clearInterval(overallTimeout);
+  console.log('Cleared overall timeout after writer finished');
+}
+```
+
+**Quality:** ✅ **Proper cleanup with multiple safeguards**
+- Intervals are cleared in all exit paths
+- No orphaned setInterval/setTimeout calls
+
+---
+
+## 5. **Electron Auto-Updater** (Lines 184-237)
+
+```javascript
+autoUpdater.autoDownload = true;
+autoUpdater.autoInstallOnAppQuit = true;
+
+autoUpdater.on('update-downloaded', (info) => {
+  // ...
+});
+```
+
+**Auto-Updater Cleanup:** ✅
+- Electron handles auto-updater cleanup automatically
+- No explicit cleanup needed (Electron manages lifecycle)
+
+---
+
+## Summary: Process Termination Quality
+
+| Component | Status | Notes |
+|-----------|--------|-------|
+| **Discord RPC** | ✅ **Good** | Properly destroyed with error handling |
+| **Main Window** | ✅ **Good** | Cleanup called on closed and before-quit |
+| **Game Process** | ✅ **Good** | Detached and unref'd on Windows |
+| **Download Intervals** | ✅ **Good** | Cleared in all exit paths |
+| **Event Listeners** | ⚠️ **Mixed** | Main listeners properly removed, but IPC handlers remain registered (normal) |
+| **Overall** | ✅ **Good** | Proper cleanup architecture |
+
+---
+
+## Potential Improvements
+
+### 1. **Add Explicit Process Tracking (Optional)**
+Currently, the launcher doesn't track child processes. We could add:
+```javascript
+// Track all spawned processes for cleanup
+const childProcesses = new Set();
+
+app.on('before-quit', () => {
+  // Kill any remaining child processes
+  for (const proc of childProcesses) {
+    if (proc && !proc.killed) {
+      proc.kill('SIGTERM');
+    }
+  }
+});
+```
+
+### 2. **Auto-Updater Resource Cleanup (Minor)**
+Add explicit cleanup for auto-updater listeners:
+```javascript
+app.on('before-quit', () => {
+  autoUpdater.removeAllListeners();
+});
+```
+
+### 3. **Graceful Shutdown Timeout (Safety)**
+Add a safety timeout to force exit if cleanup hangs:
+```javascript
+app.on('before-quit', () => {
+  const forceExitTimeout = setTimeout(() => {
+    console.warn('Cleanup timeout - forcing exit');
+    process.exit(0);
+  }, 5000);  // 5 second max cleanup time
+});
+```
+
+---
+
+## Relationship to Ghost Process Issue
+
+### Previous Issue (PowerShell processes)
+- **Root cause**: Spawned PowerShell processes weren't cleaned up in `platformUtils.js`
+- **Fixed by**: Replacing `execSync()` with `spawnSync()` + timeouts
+
+### Launcher Termination
+- **Status**: ✅ **No critical issues found**
+- **Discord RPC**: Properly cleaned up
+- **Game process**: Properly detached
+- **Intervals**: Properly cleared
+- **No memory leaks detected**
+
+The launcher's termination flow is solid. The ghost process issue was specific to PowerShell process spawning during GPU detection, not the launcher's shutdown process.
+
+---
+
+## Testing Checklist
+
+To verify proper launcher termination:
+
+- [ ] Start launcher → Close window → Check Task Manager for lingering processes
+- [ ] Start launcher → Launch game → Close launcher → Check for orphaned processes
+- [ ] Start launcher → Download something → Cancel mid-download → Check for setInterval processes
+- [ ] Disable Discord RPC → Start launcher → Close → No Discord processes remain
+- [ ] Check Windows Event Viewer → No unhandled exceptions on launcher exit
+- [ ] Multiple launch/close cycles → No memory growth in Task Manager
+
+---
+
+## Conclusion
+
+The Hytale-F2P launcher has **good shutdown hygiene**:
+- ✅ Discord RPC is properly cleaned
+- ✅ Game process is properly detached
+- ✅ Download intervals are properly cleared
+- ✅ Event handlers are properly registered
+
+The ghost process issue was **not** caused by the launcher's termination logic, but by the PowerShell GPU detection functions, which has already been fixed.

+# Steam Deck / Ubuntu LTS Crash Investigation
+
+## Status: SOLVED
+
+**Last updated:** 2026-01-27
+
+**Solution:** Replace bundled `libzstd.so` with system version.
+
+---
+
+## Problem Summary
+
+The Hytale F2P launcher's client patcher causes crashes on Steam Deck and Ubuntu LTS with the error:
+```
+free(): invalid pointer
+```
+or
+```
+SIGSEGV (Segmentation fault)
+```
+
+The crash occurs after successful authentication, specifically right after "Finished handling RequiredAssets".
+
+**Affected Systems:**
+- Steam Deck (glibc 2.41)
+- Ubuntu LTS
+
+**Working Systems:**
+- macOS
+- Windows
+- Older Arch Linux (glibc < 2.41)
+
+---
+
+## Root Cause
+
+The **bundled `libzstd.so`** in the game client is incompatible with glibc 2.41's stricter heap validation. When the game decompresses assets using this library, it triggers heap corruption detected by glibc 2.41.
+
+The crash occurs in `libzstd.so` during `free()` after "Finished handling RequiredAssets" (asset decompression).
+
+---
+
+## Solution
+
+Replace the bundled `libzstd.so` with the system's `libzstd.so.1`.
+
+### Automatic (Launcher)
+
+The launcher automatically detects and replaces `libzstd.so` on Linux systems. No manual action needed.
+
+### Manual
+
+```bash
+cd ~/.hytalef2p/release/package/game/latest/Client
+
+# Backup bundled version
+mv libzstd.so libzstd.so.bundled
+
+# Link to system version
+# Steam Deck / Arch Linux:
+ln -s /usr/lib/libzstd.so.1 libzstd.so
+
+# Debian / Ubuntu:
+ln -s /usr/lib/x86_64-linux-gnu/libzstd.so.1 libzstd.so
+
+# Fedora / RHEL:
+ln -s /usr/lib64/libzstd.so.1 libzstd.so
+```
+
+### Restore Original
+
+```bash
+cd ~/.hytalef2p/release/package/game/latest/Client
+rm libzstd.so
+mv libzstd.so.bundled libzstd.so
+```
+
+---
+
+## Why This Works
+
+1. The bundled `libzstd.so` was likely compiled with different allocator settings or an older toolchain
+2. glibc 2.41 has stricter heap validation that catches invalid memory operations
+3. The system `libzstd.so.1` is compiled with the system's glibc and uses compatible memory allocation patterns
+4. By using the system library, we avoid the incompatibility entirely
+
+---
+
+## Previous Investigation (for reference)
+
+### What Was Tried Before Finding Solution
+
+| Approach | Result |
+|----------|--------|
+| jemalloc allocator | Worked ~30% of time, not stable |
+| GLIBC_TUNABLES | No effect |
+| taskset (CPU pinning) | Single core too slow |
+| nice/chrt (scheduling) | No effect |
+| Various patching approaches | All crashed |
+
+### Key Insight
+
+The crash was in `libzstd.so`, not in our patched code. The patching just changed timing enough to expose the libzstd incompatibility more frequently.
+
+---
+
+## GDB Stack Trace (Historical)
+
+```
+#0  0x00007ffff7d3f5a4 in ?? () from /usr/lib/libc.so.6
+#1  raise () from /usr/lib/libc.so.6
+#2  abort () from /usr/lib/libc.so.6

+# Testing Auto-Updates
+
+This guide explains how to test the auto-update system during development.
+
+## Quick Start
+
+### Option 1: Test with GitHub Releases (Easiest)
+
+1. **Set up dev-app-update.yml** (already done):
+   ```yaml
+   provider: github
+   owner: amiayweb
+   repo: Hytale-F2P
+   ```
+
+2. **Lower your current version** in `package.json`:
+   - Change version to something lower than what's on GitHub (e.g., `2.0.1` if GitHub has `2.0.3`)
+
+3. **Run the app in dev mode**:
+   ```bash
+   npm run dev
+   # or
+   npm start
+   ```
+
+4. **The app will check for updates** 3 seconds after startup
+   - If a newer version exists on GitHub, it will detect it
+   - Check the console logs for update messages
+
+### Option 2: Test with Local HTTP Server
+
+For more control, you can set up a local server:
+
+1. **Create a test update server**:
+   ```bash
+   # Create a test directory
+   mkdir -p test-updates
+   cd test-updates
+   ```
+
+2. **Build a test version** with a higher version number:
+   ```bash
+   # In package.json, set version to 2.0.4
+   npm run build
+   ```
+
+3. **Copy the generated files** to your test server:
+   - Copy `dist/latest.yml` (or `latest-mac.yml` for macOS)
+   - Copy the built installer/package
+
+4. **Start a simple HTTP server**:
+   ```bash
+   # Using Python
+   python3 -m http.server 8080
+   
+   # Or using Node.js http-server
+   npx http-server -p 8080
+   ```
+
+5. **Update dev-app-update.yml** to point to local server:
+   ```yaml
+   provider: generic
+   url: http://localhost:8080
+   ```
+
+6. **Run the app** and it will check your local server
+
+## Testing Steps
+
+### 1. Prepare Test Environment
+
+**Current version**: `2.0.3` (in package.json)
+**Test version**: `2.0.4` (on GitHub or local server)
+
+### 2. Run the App
+
+```bash
+npm run dev
+```
+
+### 3. Watch for Update Events
+
+The app will automatically check for updates 3 seconds after startup. Watch the console for:
+
+```
+Checking for updates...
+Update available: 2.0.4
+```
+
+### 4. Check Console Logs
+
+Look for these messages:
+- `Checking for updates...` - Update check started
+- `Update available: 2.0.4` - New version found
+- `Download speed: ...` - Download progress
+- `Update downloaded: 2.0.4` - Download complete
+
+### 5. Test UI Integration
+
+The app sends these events to the renderer:
+- `update-checking`
+- `update-available` (with version info)
+- `update-download-progress` (with progress data)
+- `update-downloaded` (ready to install)
+
+You can listen to these in your frontend code to show update notifications.
+
+## Manual Testing
+
+### Trigger Manual Update Check
+
+You can also trigger a manual check via IPC:
+```javascript
+// In renderer process
+const result = await window.electronAPI.invoke('check-for-updates');
+console.log(result);
+```
+
+### Install Update
+
+After an update is downloaded:
+```javascript
+// In renderer process
+await window.electronAPI.invoke('quit-and-install-update');
+```
+
+## Testing Scenarios
+
+### Scenario 1: Update Available
+1. Set `package.json` version to `2.0.1`
+2. Ensure GitHub has version `2.0.3` or higher
+3. Run app → Should detect update
+
+### Scenario 2: Already Up to Date
+1. Set `package.json` version to `2.0.3`
+2. Ensure GitHub has version `2.0.3` or lower
+3. Run app → Should show "no update available"
+
+### Scenario 3: Prerelease Version
+1. Set `package.json` version to `2.0.2b`
+2. Ensure GitHub has version `2.0.3`
+3. Run app → Should detect update (prerelease < release)
+
+## Troubleshooting
+
+### Update Not Detected
+
+1. **Check dev-app-update.yml exists** in project root
+2. **Verify dev mode is enabled** - Check console for "Dev update mode enabled"
+3. **Check version numbers** - Remote version must be higher than current
+4. **Check network** - App needs internet to reach GitHub/local server
+5. **Check logs** - Look for error messages in console
+
+### Common Errors
+
+- **"Cannot find module 'electron-updater'"**: Run `npm install`
+- **"Update check failed"**: Check network connection or GitHub API access
+- **"No update available"**: Version comparison issue - check versions
+
+### Debug Mode
+
+Enable more verbose logging by checking the console output. The logger will show:
+- Update check requests
+- Version comparisons
+- Download progress
+- Any errors
+
+## Testing with Real GitHub Releases
+
+For the most realistic test:
+
+1. **Create a test release on GitHub**:
+   - Build the app with version `2.0.4`
+   - Create a GitHub release with tag `v2.0.4`
+   - Upload the built files
+
+2. **Lower your local version**:
+   - Set `package.json` to `2.0.3`
+
+3. **Run the app**:
+   - It will check GitHub and find `2.0.4`
+   - Download and install the update
+
+## Notes
+
+- **Dev mode only works when app is NOT packaged** (`!app.isPackaged`)
+- **Production builds** ignore `dev-app-update.yml` and use the built-in `app-update.yml`
+- **macOS**: Code signing is required for updates to work in production
+- **Windows**: NSIS installer is required for auto-updates
+
+## Next Steps
+
+Once testing is complete:
+1. Remove or comment out `forceDevUpdateConfig` for production
+2. Ensure proper code signing for macOS
+3. Set up CI/CD to automatically publish releases

+# UUID/Skin Reset Bug Fix Plan
+
+## Problem Summary
+
+Players experience random skin/cosmetic resets without intentionally changing anything. The root cause is that the UUID system has multiple failure points that can silently generate new UUIDs or use the wrong UUID during gameplay.
+
+**Impact**: Players lose their customized cosmetics/skins randomly, causing frustration and confusion.
+
+**Status**: ✅ **FIXED** - All critical and high priority bugs have been addressed.
+
+---
+
+## Implementation Summary
+
+### What Was Fixed
+
+| Bug | Severity | Status | Description |
+|-----|----------|--------|-------------|
+| BUG-001 | Critical | ✅ Fixed | Username not loaded before play click |
+| BUG-002 | High | ✅ Fixed | isFirstLaunch() always returns true |
+| BUG-003 | Critical | ✅ Fixed | Silent config corruption returns empty object |
+| BUG-004 | Critical | ✅ Fixed | Non-atomic config writes |
+| BUG-005 | High | ✅ Fixed | Username fallback to 'Player' |
+| BUG-006 | Medium | ✅ Fixed | Launch overwrites username every time |
+| BUG-007 | Medium | ✅ Fixed | Dual UUID systems (playerManager vs config) |
+| BUG-008 | High | ✅ Fixed | Error returns random UUID |
+| BUG-009 | Medium | ✅ Fixed | Username case sensitivity |
+| BUG-010 | Medium | ⏳ Pending | Migration marks complete on partial failure |
+| BUG-011 | Medium | ⏳ Pending | Race condition on concurrent config access |
+| BUG-012 | High | ✅ Fixed | UUID modal isCurrent flag broken |
+| BUG-013 | High | ✅ Fixed | UUID setting uses unsaved DOM username |
+| BUG-014 | Medium | ✅ Fixed | No way to switch between saved identities |
+| BUG-015 | High | ✅ Fixed | installGame saves username (overwrites good value) |
+| BUG-016 | High | ✅ Fixed | Username rename creates new UUID instead of preserving |
+| BUG-017 | Medium | ✅ Fixed | UUID list not refreshing when player name changes |
+| BUG-018 | Low | ✅ Fixed | Custom UUID input doesn't allow copy/paste |
+
+---
+
+## User Scenario Analysis
+
+All user scenarios have been analyzed for UUID/username persistence:
+
+| Scenario | Risk | Status | Details |
+|----------|------|--------|---------|
+| **Fresh Install** | Low | ✅ Safe | firstLaunch.js reads but doesn't modify username/UUID |
+| **Username Change** | Low | ✅ Safe | Rename preserves UUID, user-initiated saves work correctly |
+| **Auto-Update** | Low | ✅ Safe | Config is on disk before update, backup recovery available |
+| **Manual Update** | Low | ✅ Safe | Config file persists across manual updates |
+| **Different Install Location** | Low | ✅ Safe | Config uses central app directory, not install-relative |
+| **Repair Game** | Low | ✅ Safe | repairGame() doesn't touch config |
+| **UUID Modal** | Low | ✅ Fixed | Fixed isCurrent badge, unsaved username bug, added switch button |
+| **Profile Switch** | Low | ✅ Safe | Profiles only control mods/java, not username/UUID |
+| **Branch Change** | Low | ✅ Safe | Only changes game version, not identity |
+
+---
+
+## Files Modified
+
+| File | Changes |
+|------|---------|
+| `backend/core/config.js` | Atomic writes, backup/recovery, validation, case-insensitive UUID lookup, checkLaunchReady(), username rename preserves UUID |
+| `backend/managers/gameLauncher.js` | Pre-launch validation, removed saveUsername call |
+| `backend/managers/gameManager.js` | Removed saveUsername call from installGame |
+| `backend/services/playerManager.js` | Marked DEPRECATED, throws on error, retry logic |
+| `backend/launcher.js` | Export new functions (checkLaunchReady, hasUsername, etc.) |
+| `GUI/js/launcher.js` | Uses checkLaunchReady API, blocks launch if no username |

+
+---
+
+## Detailed Bug List & Fixes
+
+---
+
+### BUG-001: Username Not Loaded Before Play Click (CRITICAL) ✅ FIXED
+
+**Category**: A - Race Condition
+
+**Location**:
+- `GUI/js/launcher.js`
+- `GUI/js/settings.js`
+
+**Problem**: If user clicks Play before settings DOM initializes, returns 'Player' silently.
+
+**Fix Applied**:
+- launcher.js now uses `checkLaunchReady()` API to validate before launch
+- Loads username from backend config (single source of truth)
+- Blocks launch and shows error if no username configured
+- Navigates user to settings page to set username
+
+---
+
+### BUG-002: `isFirstLaunch()` Always Returns True (HIGH) ✅ FIXED
+
+**Category**: B - Silent Failure
+
+**Location**: `backend/core/config.js`
+
+**Problem**: Function always returns `true` even when user has data (typo: `return true` instead of `return false`).
+
+**Fix Applied**:
+- Fixed return statement: `return true` → `return false`
+
+---
+
+### BUG-003: Silent Config Corruption Returns Empty Object (CRITICAL) ✅ FIXED
+
+**Category**: B - Silent Failure
+
+**Location**: `backend/core/config.js`
+
+**Problem**: Corrupted config silently returns `{}`, causing UUID regeneration.
+
+**Fix Applied**:
+- Added config validation after load
+- Implemented backup config system (config.json.bak)
+- Tries loading backup if primary fails
+- Logs detailed errors for debugging
+
+---
+
+### BUG-004: Non-Atomic Config Writes (CRITICAL) ✅ FIXED
+
+**Category**: C - Data Integrity
+
+**Location**: `backend/core/config.js`
+
+**Problem**: Direct write can corrupt file if interrupted. Silent error logging.
+
+**Fix Applied**:
+- Atomic write: write to temp file → verify JSON → backup current → rename
+- Throws error on save failure (no silent continuation)
+- Cleans up temp file on failure
+
+---
+
+### BUG-005: Username Fallback to 'Player' (HIGH) ✅ FIXED
+
+**Category**: B - Silent Failure
+
+**Location**: `backend/core/config.js`
+
+**Problem**: Missing username silently falls back to 'Player', causing wrong UUID.
+
+**Fix Applied**:
+- `loadUsername()` returns `null` instead of 'Player'
+- Added `loadUsernameWithDefault()` for display purposes
+- Added `hasUsername()` helper function
+- All callers updated to handle null case explicitly
+
+---
+
+### BUG-006: Launch Overwrites Username Every Time (MEDIUM) ✅ FIXED
+
+**Category**: D - Design Issue
+
+**Location**: `backend/managers/gameLauncher.js`
+
+**Problem**: If playerName parameter is wrong, it overwrites the saved username.
+
+**Fix Applied**:
+- Removed `saveUsername()` call from launch process
+- Username only saved when user explicitly changes it in Settings
+- Launch loads username from config (single source of truth)
+
+---
+
+### BUG-007: Dual UUID Systems (playerManager vs config) (MEDIUM) ✅ FIXED
+
+**Category**: D - Design Issue
+
+**Location**:
+- `backend/services/playerManager.js` → `player_id.json`
+- `backend/core/config.js` → `config.json` → `userUuids`
+
+**Problem**: Two independent UUID systems can desync.
+
+**Fix Applied**:
+- `playerManager.js` marked as DEPRECATED
+- All code uses `config.js` `getUuidForUser()`
+- Migration function added for legacy `player_id.json`
+
+---
+
+### BUG-008: Error Returns Random UUID (HIGH) ✅ FIXED
+
+**Category**: B - Silent Failure
+
+**Location**: `backend/services/playerManager.js`
+
+**Problem**: Any error generates random UUID, losing player identity.
+
+**Fix Applied**:
+- Now throws error instead of returning random UUID
+- Retry logic added (3 attempts before failure)
+- Caller must handle the error appropriately
+
+---
+
+### BUG-009: Username Case Sensitivity (MEDIUM) ✅ FIXED
+
+**Category**: D - Design Issue
+
+**Location**: `backend/core/config.js`
+
+**Problem**: "PlayerOne" and "playerone" are different UUIDs.
+
+**Fix Applied**:
+- `getUuidForUser()` uses case-insensitive lookup
+- Username stored with ORIGINAL case (preserves "Sanasol", "SaAnAsOl", etc.)
+- Lookup normalized to lowercase for matching
+- Case changes update the stored key while preserving UUID
+
+---
+
+### BUG-010: Migration Marks Complete Even on Partial Failure (MEDIUM) ⏳ PENDING
+
+**Category**: C - Data Integrity
+
+**Location**: `backend/utils/userDataMigration.js`
+
+**Problem**: Partial copy is marked as complete, preventing retry.
+
+**Status**: Not yet implemented - low priority since migration runs once.
+
+---
+
+### BUG-011: Race Condition on Concurrent Config Access (MEDIUM) ⏳ PENDING
+
+**Category**: A - Race Condition
+
+**Location**: `backend/core/config.js`
+
+**Problem**: No file locking - concurrent processes can overwrite each other.
+
+**Status**: Not yet implemented - would require `proper-lockfile` package. Low risk since launcher is single-instance.
+
+---
+
+### BUG-012: UUID Modal isCurrent Flag Broken (HIGH) ✅ FIXED
+
+**Category**: D - Design Issue
+
+**Location**: `main.js` - `get-all-uuid-mappings` IPC handler
+
+**Problem**: Case-sensitive comparison between normalized key (lowercase) and current username.
+```javascript
+// BROKEN:
+isCurrent: username === loadUsername()  // "player1" === "Player1" → FALSE
+```
+
+**Fix Applied**:
+- IPC handler now uses `getAllUuidMappingsArray()` from config.js
+- This function correctly compares against normalized username
+
+---
+
+### BUG-013: UUID Setting Uses Unsaved DOM Username (HIGH) ✅ FIXED
+
+**Category**: B - Silent Failure
+
+**Location**: `GUI/js/settings.js` - `performSetCustomUuid()`
+
+**Problem**: Gets username from DOM input field instead of saved config.
+```javascript
+// BROKEN:
+const username = getCurrentPlayerName();  // From UI input, not saved!
+```
+
+**Risk Scenario**: User types new name but doesn't save → opens UUID modal → sets custom UUID → UUID gets set for unsaved name while config has old name.
+
+**Fix Applied**:
+- Now loads username from backend config via `window.electronAPI.loadUsername()`
+- Shows error if no username is saved
+
+---
+
+### BUG-014: No Way to Switch Between Saved Identities (MEDIUM) ✅ FIXED
+
+**Category**: D - Design Issue
+
+**Location**: `GUI/js/settings.js` - UUID modal
+
+**Problem**: UUID modal showed list of usernames/UUIDs but no way to switch to a different identity.
+
+**Fix Applied**:
+- Added `switchToUsername()` function
+- New switch button (user-check icon) on non-current entries
+- Confirmation dialog before switching
+- Updates username input and refreshes UUID display
+
+---
+
+### BUG-015: installGame Saves Username (HIGH) ✅ FIXED
+
+**Category**: D - Design Issue
+
+**Location**: `backend/managers/gameManager.js` - `installGame()`
+
+**Problem**: `saveUsername(playerName)` call could overwrite good username with 'Player' default.
+
+**Fix Applied**:
+- Removed `saveUsername()` call from `installGame()`
+- Username only saved when user explicitly changes it in Settings
+
+---
+
+### BUG-016: Username Rename Creates New UUID (HIGH) ✅ FIXED
+
+**Category**: D - Design Issue
+
+**Location**: `backend/core/config.js` - `saveUsername()`
+
+**Problem**: When user changes their player name, a new UUID was generated instead of preserving the existing one. User's identity (cosmetics/skins) was lost on every name change.
+
+**Symptom**: Change "Player1" to "NewPlayer" → gets completely new UUID → loses all cosmetics.
+
+**Fix Applied**:
+- `saveUsername()` now handles UUID mapping renames atomically
+- When renaming: old username's UUID is moved to new username
+- When switching to existing identity: uses that identity's existing UUID
+- Case changes only: updates key casing, preserves UUID
+- Both username and userUuids saved in single atomic operation
+
+**Behavior After Fix**:
+```javascript
+// Rename: "Player1" → "NewPlayer"
+// Before: Player1=uuid-123, NewPlayer=uuid-NEW (wrong!)
+// After:  NewPlayer=uuid-123 (same UUID, just renamed)
+
+// Switch to existing: "Player1" → "ExistingPlayer"
+// Uses ExistingPlayer's existing UUID (switching identity)
+
+// Case change: "Player1" → "PLAYER1"
+// UUID preserved, key updated to new case
+```
+
+---
+
+### BUG-017: UUID List Not Refreshing on Name Change (MEDIUM) ✅ FIXED
+
+**Category**: E - UI/UX Issue
+
+**Location**: `GUI/js/settings.js` - `savePlayerName()`
+
+**Problem**: After changing player name in settings, the UUID modal list didn't refresh. The "Current" badge showed on the old username instead of the new one.
+
+**Fix Applied**:
+- Added `await loadAllUuids()` call after `loadCurrentUuid()` in `savePlayerName()`
+- UUID modal now shows correct "Current" badge after name changes
+
+---
+
+### BUG-018: Custom UUID Input Doesn't Allow Copy/Paste (LOW) ✅ FIXED
+
+**Category**: E - UI/UX Issue
+
+**Location**: `GUI/style.css`, `main.js`
+
+**Problem**: Two issues prevented copy/paste:
+1. The body element has `select-none` class (Tailwind) which applies `user-select: none` globally
+2. Electron's `setIgnoreMenuShortcuts(true)` was blocking Ctrl+V/C/X/A shortcuts
+
+**Fix Applied**:
+- Added `user-select: text` with all vendor prefixes to `.uuid-input` class
+- Removed `setIgnoreMenuShortcuts(true)` from main.js
+- Added early return in `before-input-event` handler to allow Ctrl/Cmd + V/C/X/A shortcuts
+- DevTools shortcuts (Ctrl+Shift+I/J/C, F12) remain blocked
+
+---
+
+## Translation Keys Added
+
+The following translation keys were added to `GUI/locales/en.json`:
+
+```json
+{
+  "notifications": {
+    "noUsername": "No username configured. Please save your username first.",
+    "switchUsernameSuccess": "Switched to \"{username}\" successfully!",
+    "switchUsernameFailed": "Failed to switch username",
+    "playerNameTooLong": "Player name must be 16 characters or less"
+  },
+  "confirm": {
+    "switchUsernameTitle": "Switch Identity",
+    "switchUsernameMessage": "Switch to username \"{username}\"? This will change your current player identity.",
+    "switchUsernameButton": "Switch"
+  }
+}
+```
+
+---
+
+## Testing Checklist
+
+After implementing fixes, verify:
+
+- [x] Launch with freshly installed launcher - UUID persists
+- [x] Change username in settings - UUID preserved (renamed, not new)
+- [x] Config corruption - recovers from backup
+- [x] Click Play immediately after opening - correct UUID used
+- [x] Manual update from GitHub - UUID persists
+- [x] Username with different casing - same UUID used, case preserved
+- [x] UUID modal shows correct "Current" badge
+- [x] UUID modal refreshes after username change
+- [x] Switch identity from UUID modal works
+- [x] Profile switching doesn't affect username/UUID
+- [x] Custom UUID input allows copy/paste
+
+---
+
+## Architecture: How UUID/Username Persistence Works
+
+**Config Structure** (`config.json`):
+```json
+{
+  "username": "CurrentPlayer",
+  "userUuids": {
+    "Sanasol": "uuid-123-abc",
+    "SaAnAsOl": "uuid-456-def",
+    "Player1": "uuid-789-ghi"
+  },
+  "hasLaunchedBefore": true
+}
+```
+
+**Key Design Decisions**:
+- Username stored with ORIGINAL case (e.g., "Sanasol", "SaAnAsOl")
+- UUID lookup is case-insensitive (normalized to lowercase for matching)
+- Username rename preserves UUID (atomic rename operation)
+- Profile switching does NOT affect username/UUID (shared globally)
+- All config writes use atomic pattern: temp file → verify → backup → rename
+- Automatic backup recovery if config corruption detected
+
+**Data Flow**:
+1. User sets username in Settings → `saveUsername()` handles rename logic → saves to config.json
+2. If renaming: UUID moved from old name to new name (same UUID preserved)
+3. Launch game → `checkLaunchReady()` validates username exists
+4. Launch game → `getUuidForUser(username)` gets UUID (case-insensitive lookup)
+5. UUID modal → shows all username→UUID mappings from config
+6. Switch identity → saves new username → gets that username's UUID
+
+---
+
+## Success Criteria
+
+- ✅ Zero silent UUID regeneration
+- ✅ Config corruption recovery working
+- ✅ No UUID change without explicit user action
+- ✅ Username rename preserves UUID
+- ✅ Username case is preserved in display
+- ✅ UUID modal correctly identifies current user
+- ✅ UUID modal refreshes on changes
+- ✅ Users can switch between saved identities
+- ✅ Copy/paste works in UUID input
+
+---
+
+## Remaining Work
+
+1. **BUG-010**: Verify migration completeness before marking done (low priority)
+2. **BUG-011**: Add file locking with `proper-lockfile` (low priority - single instance)
+3. Add telemetry for config load failures and UUID regeneration events
+
+## Completed Additional Tasks
+
+- ✅ Added translation keys to all 10 locale files (de-DE, es-ES, fr-FR, id-ID, pl-PL, pt-BR, ru-RU, sv-SE, tr-TR, en)
