+## 2026-07-03 - Add ARIA Labels to Diff View Buttons
+**Learning:** Adding descriptive aria-label attributes to buttons that contain text (e.g., Undo, Keep) can provide more specific context for screen reader users (e.g., Undo changes, Keep changes) in critical interaction areas like a diff viewer.
+**Action:** Consistently evaluate action buttons for screen reader context and add aria-label attributes where the visible text might be too brief or ambiguous out of context.
