+# Development Roadmap
+
+## Completed foundations
+
+- Tauri + React/TypeScript desktop shell, themes, navigation, and accessibility
+  contrast mode.
+- Versioned JSON profiles with built-in templates and import/export.
+- Generic, non-copyrighted controller visualization.
+- Real evdev controller enumeration/capability probing plus a safe simulated
+  fallback for development without hardware.
+- Pure, tested stick/trigger response transformation math.
+
+## Next engineering milestones
+
+1. Connect the reader to the transform pipeline and a managed uinput virtual
+   controller with safe cleanup on disconnect/shutdown.
+2. Finish advanced mappings (macros, turbo timing, shift layers, hold/toggle
+   semantics) in the output pipeline.
+3. Complete calibration sampling and custom curve editing.
+4. Add executable-based profile switching and the support-bundle exporter.
+5. Validate hardware behavior across USB, Bluetooth, and receiver modes; build
+   distributable Linux packages.
+
+## Safety principles
+
+- No firmware changes.
+- No undocumented vendor commands.
+- No root application process.
+- Never create a virtual output device unless requested and permission checks
+  pass.
+- Release virtual controls on disconnect and application shutdown.
