 ## 2024-07-14 - Native Keyboard Submission with Forms for Modals
 **Learning:** Modals designed with plain `<div>` elements as wrappers instead of `<form>` lack native keyboard submission support, forcing users to switch from keyboard to mouse to confirm actions like "Save".
 **Action:** When designing modals or popups containing inputs, always use a `<form>` element to wrap the content, handle the `onSubmit` event (calling `e.preventDefault()`), and set the primary confirmation button to `type="submit"` to enable seamless Enter-key submission for keyboard users.
+## 2026-07-15 - [Accessible Edge Deletion Modal]
+**Learning:** In edge configuration modals (like EditEdgeModal.tsx), the generic "삭제" (delete) button lacks screen reader context. Because edge deletion is a destructive action, users relying on assistive technology may trigger it without fully understanding what is being deleted.
+**Action:** Always provide contextual `aria-label`s on generic action buttons within relation modals. For example, adding `aria-label="관계 삭제"` to the delete button significantly improves clarity.
