+## [0.12.0] - 2026-05-22
+### Added
+- **Guided diagnostic in the GUI.** Each game on the **Games** page now has a **Run Diagnostic**
+  button → a focused, game-tagged capture starts and a recording banner appears (live sample
+  count, GPU-lost indicator) with **Finish & analyze** / **Discard**. Finishing opens a results
+  dialog: the window-scoped capture summary (peak temps/power, events, last samples) plus the
+  health findings as cards. The banner persists/restores if you navigate away and back while a
+  capture is running. Shares `core/diagnostic.py` with the CLI (one flow, three front-ends).
