+# 🛡️ Cheater Analytics — Feature Branch
+
+> **Branch:** `claude/focused-pasteur-2pCsw`  
+> **Based on:** Rust+ Desktop v5.4.0 by [Pronwan](https://github.com/Pronwan)  
+> **Status:** Ready for review / merge to main
+
+---
+
+## What Was Built
+
+This branch adds a **Cheater-to-Player Ratio Analytics** panel to Rust+ Desktop — a local, privacy-respecting tool that helps server admins track, flag, and report suspected cheaters during a wipe.
+
+No IP collection. No hardware fingerprinting. No Discord scraping. All data stays local.
+
+---
+
+## Feature Overview
+
+### Shield Button
+A new shield icon button (🛡️) appears in every server card header. Clicking it opens the Cheater Analytics sidebar panel.
+
+### Current Wipe Snapshot
+Live metrics updated as you flag players:
+
+| Metric | Description |
+|---|---|
+| **Players** | Active player count (manually entered) |
+| **Confirmed** | Players with confirmed bans or marked confirmed |
+| **Suspected** | Flagged players not yet confirmed |
+| **Risk %** | `(Confirmed + Suspected) / Players × 100` |
+| **Risk Level** | Low / Moderate / High / Critical colour-coded band |
+
+Risk bands:
+- 🟢 **Low** — 0–5%
+- 🟡 **Moderate** — 5–15%
+- 🟠 **High** — 15–30%
+- 🔴 **Critical** — >30%
+
+### Flag a Player
+Expand the **+ Flag a Player** section to add a suspect:
+- Steam ID (triggers automatic VAC/game ban lookup via Steam public API)
+- Display name, confidence level, flag source, notes, evidence link
+
+### Report & Export
+Once players are flagged, one click sends a full report:
+
+| Button | Action |
+|---|---|
+| 📋 **Copy F7 List** | Builds a plain-text F7-style report, saves to Desktop, copies to clipboard |
+| 💾 **Export CSV** | Saves a CSV of all flagged players to Desktop |
+| 📨 **Send Discord** | Posts a formatted embed to your Discord server via webhook |
+
+The Discord webhook URL is entered once and **persisted automatically** — it pre-fills every time you open the panel.
+
+### Discord Report Example
+
+![Discord report embed showing flagged players](docs/discord_report_preview.png)
+
+The embed includes server name, wipe date, confirmed/suspected counts, and a full list of flagged players with confidence level, source, and evidence notes.
+
+---
+
+## New Files
+
+| File | Purpose |
+|---|---|
+| `RustPlusDesktop/Models/CheaterRecord.cs` | Data model for a flagged player |
+| `RustPlusDesktop/Models/CheaterAnalyticsSnapshot.cs` | Computed wipe snapshot with ratio + risk band |
+| `RustPlusDesktop/Services/CheaterAnalyticsService.cs` | Local JSON persistence and snapshot builder |
+| `RustPlusDesktop/Services/SteamBanLookupService.cs` | Steam `ISteamUser/GetPlayerBans` public API wrapper |
+| `RustPlusDesktop/Services/CheaterReportService.cs` | CSV, F7 text, and Discord webhook report builder |
+| `RustPlusDesktop/ViewModels/CheaterAnalyticsViewModel.cs` | MVVM ViewModel with all commands |
+| `RustPlusDesktop/Views/CheaterAnalyticsPanel.xaml` | WPF sidebar panel UI |
+| `RustPlusDesktop/Views/CheaterAnalyticsPanel.xaml.cs` | Code-behind |
+
+### Modified Files
+
+| File | Change |
+|---|---|
+| `RustPlusDesktop/MainWindow.xaml` | Shield button + panel overlay |
+| `RustPlusDesktop/MainWindow.xaml.cs` | Button handler, lazy ViewModel init |
+
+---
+
+## Data & Privacy
+
+- All flagged player data is stored locally at `%AppData%\RustPlusDesk\cheater_records_{serverId}.json`
+- Snapshot history at `%AppData%\RustPlusDesk\cheater_snapshots_{serverId}.json`
+- Discord webhook URL cached at `%AppData%\RustPlusDesk\cache\cheater_discord_webhook.json`
+- The only outbound network calls are:
+  - Steam public `ISteamUser/GetPlayerBans` API (optional, requires user-provided API key)
+  - Discord webhook POST (only when user clicks **Send Discord**)
+
+---
+
+## How to Test Locally
+
+```powershell
+# Clone or pull the branch
+git clone https://github.com/Pronwan/rustplus-desktop-qa.git
+git checkout claude/focused-pasteur-2pCsw
+
+cd RustPlusDesktop
+
+# Create required local secrets file (gitignored)
+# Copy ObfuscatedSecrets.cs from your working install or create a stub
+
+dotnet run
+```
+
+Then click the 🛡️ shield button on any server card.
+
+---
+
+## Discord Webhook Setup
+
+1. Open your Discord server → **Server Settings → Integrations → Webhooks**
+2. Click **New Webhook**, pick a channel, copy the URL
+3. Paste into the webhook box in the Cheater Analytics panel
+4. Click **📨 Send Discord** — the URL saves automatically for next time
