-# Tauri + Vanilla
+# WVU Medicine Help Alert Web Client
 
-This template should help get you started developing with Tauri in vanilla HTML, CSS and Javascript.
+A lightweight Tauri-based desktop wrapper for the WVU Medicine PinPoint HelpAlert duress alarm system. Built to replace the vendor's crashing desktop client with a stable, tray-resident application that brings alerts to the foreground automatically.
 
-## Recommended IDE Setup
+## Why This Exists
 
-- [VS Code](https://code.visualstudio.com/) + [Tauri](https://marketplace.visualstudio.com/items?itemName=tauri-apps.tauri-vscode) + [rust-analyzer](https://marketplace.visualstudio.com/items?itemName=rust-lang.rust-analyzer)
+The vendor's native desktop client crashes hospital workstations. The web version works but has two problems: users get logged out due to inactivity, and browser notifications don't reliably surface when the tab is backgrounded. This app solves both by wrapping the web client in a persistent Tauri window with native alert detection.
+
+## How It Works
+
+1. The app loads PinPoint's web login page in a native webview
+2. After login, the user clicks "Alerts" to navigate to the HelpAlert GWT page
+3. Injected JavaScript monitors the DOM every 2 seconds for new alerts (identified by "Claim" buttons and "Elapsed Time" markers)
+4. When a new alert is detected, the app calls into the Rust backend which unminimizes, focuses, and temporarily pins the window on top
+5. Closing the window minimizes to the system tray instead of exiting — the app stays running and monitoring
+
+## Architecture
+
+- **Frontend:** Vendor's HelpAlert web app loaded directly in the Tauri webview, no custom UI
+- **Injection:** `src/inject.js` handles `window.open()` interception (alerts page opens in same window instead of a new tab) and DOM-based alert detection
+- **Backend:** Rust/Tauri handles system tray, window management, and the `alert_detected` command that brings the window to the foreground
+- **IPC:** JavaScript detects alerts → invokes Tauri command → Rust brings window to front
+
+## Prerequisites
+
+- Rust toolchain (`rustup`)
+- Tauri CLI: `cargo install tauri-cli --version "^2"`
+- For Windows cross-compilation from Linux: `x86_64-pc-windows-gnu` target
+- WiX Toolset (for MSI installer generation)
+
+## WRY Fork Requirement
+
+This project requires a forked version of [wry](https://github.com/tauri-apps/wry) (Tauri's WebView library). The vendor's HelpAlert page uses GWT (Google Web Toolkit), which declares a global `ipc` variable. WRY also declares `window.ipc` for its IPC bridge, causing a collision that crashes the GWT page.
+
+The fork renames WRY's `ipc` to `__wry_ipc` in `src/webview2/mod.rs` (line 897), resolving the collision.
+
+The fork is referenced in `src-tauri/Cargo.toml`:
+
+```toml
+[patch.crates-io]
+wry = { path = "../../wry" }
+```
+
+Adjust the path to match your local wry fork location.
+
+## Building
+
+### Development
+
+```bash
+cargo tauri dev
+```
+
+### Release (Windows cross-compile from Linux)
+
+```bash
+cargo tauri build -- --target x86_64-pc-windows-gnu
+```
+
+The MSI installer will be in `src-tauri/target/x86_64-pc-windows-gnu/release/bundle/msi/`.
+
+The installer bundles the WebView2 runtime offline, so target machines don't need internet access.
+
+### Standalone EXE
+
+The raw `.exe` is also available at `src-tauri/target/x86_64-pc-windows-gnu/release/` but requires WebView2 to already be installed on the target machine.

+└── README.md
+```
+
+## Configuration
+
+### Adding the vendor URL
+
+The vendor URL is set in `lib.rs`:
+
+```rust
+let url = WebviewUrl::External("https://helpalert.wvumedicine.org".parse().unwrap());
+```
+
+### Alert detection tuning
+
+Alert detection in `inject.js` looks for lines preceding "Geo:" in the page text. If the vendor changes their alert format, update the detection logic in the `setInterval` callback.
+
+### Polling interval
+
+The DOM is checked every 2000ms (2 seconds). Adjust the `setInterval` delay in `inject.js` if needed.
+
+## Deployment Notes
+
+- Target machines need Windows 10 or 11
+- The MSI installer includes WebView2 runtime (offline) — no internet required
+- The app installs per-machine by default
+- Users should be instructed that closing the window minimizes to tray, and "Quit" in the tray menu is the actual exit
+
+## Known Limitations
+
+- Alert detection relies on DOM text parsing ("Geo:" pattern preceding alert names). If the vendor updates their GWT UI significantly, detection may need adjustment.
+- GWT class names are obfuscated and change between builds, so selectors are text-based rather than class-based.
+- Session keepalive has not been implemented yet — if the session times out, the user must re-authenticate manually. Testing suggests the session may persist indefinitely while the app is running.
+- The wry fork must be kept in sync with upstream when updating Tauri.
