+Gotcha is a lightweight Gitea client with a reusable Rust core, a CLI, and a

   typed Gitea 1.25 API and model surface
 - `gotcha`: CLI for typed common operations and arbitrary API requests

-## Direction
+## Architecture
 
-1. Exercise and type API areas in the CLI: repositories, issues and pull
-   requests, Actions, notifications, organizations, packages, administration.
-2. Add the Slint shell and move proven read workflows into touch-first screens.
-3. Add write workflows and iOS integrations such as sharing, notifications,
-   and background refresh.
+The Rust core owns Gitea access, validation, presentation records, preferences,
+favorites, and Keychain-backed credentials. UniFFI generates the Swift bridge
+in `ios/Generated`. UIKit owns navigation, lists, text input, menus, scrolling,
+pull-to-refresh, appearance, and other platform behavior.
+
+New API workflows should first be exercised and typed in the CLI, then exposed
+through the Rust core and presented with native UIKit controls. Future work
+includes write workflows and iOS integrations such as sharing, notifications,
+and background refresh.
