 * **Nix Flake Dev Environment (`flake.nix`)**: Fully configured with JDK 17, Android SDK (platforms 34-36), `ktlint`, and Gradle.
 * **Scaffolding & Build Pipeline**: Android Jetpack Compose project compiles cleanly using `./gradlew assembleDebug`.
 * **Code Formatting**: Code formatting checks integrated using `ktlint` (`./gradlew ktlintCheck`).
-* **Unit Testing Suite**: Verified with `./gradlew test` (AuthManager, EventParser, ConnectViewModel, ChatViewModel).
+* **Unit Testing Suite**: Verified with `./gradlew test` (AuthManager, EventParser, ConnectViewModel, ChatViewModel, and new viewmodels/integration tests).
 * **Network Capabilities**: Cleartext traffic enabled in `AndroidManifest.xml` to allow connection to local networks (e.g., `192.168.1.18` to `192.168.1.48`).
 * **Git Repository**: Initialized and linked with GitHub (`https://github.com/Hy4ri/hermes-mobile.git`).

-* **Profiles Management Screen (`ProfilesScreen`)**: Switch active profile, update soul personality description (`PUT /api/profiles/{name}/soul`), and switch AI model providers.
-* **Toolsets Screen (`ToolsetsScreen`)**: List and toggle toolsets (`GET/PUT /api/tools/toolsets`) to enable/disable specific tool groups (e.g., Web Search, Python local run).
-* **Achievements Screen (`AchievementsScreen`)**: Displays a gamified list of discovered/locked/unlocked achievements with progress bars (`GET /api/plugins/hermes-achievements/achievements`).
-* **Device Pairing Screen (`PairingScreen`)**: List pending approvals, list approved devices, approve new pairings (`POST /api/pairing/approve`), and revoke paired access (`POST /api/pairing/revoke`).
-* **Raw Config Editor (`ConfigScreen`)**: Live edit `/api/config/raw` (reads and updates `config.yaml` with resolved path mapping).
-* **MCP Servers Management (`McpServersScreen`)**: List MCP servers (`GET /api/mcp/servers`), toggle status, test server connection (`POST /api/mcp/servers/{name}/test`), and delete servers (`DELETE /api/mcp/servers/{name}`).
-* **Webhooks Management (`WebhooksScreen`)**: List webhook callback subscriptions (`GET /api/webhooks`), view event targets, and globally toggle webhooks status (`POST /api/webhooks/enable`).
-* **Model Configuration (`ModelScreen`)**: Inspect model providers list (`GET /api/model/options`) with available models, auth requirements, and current indicators.
