## 2025-05-19 - Dynamic ARIA labels and robust disabled states for sidebar actions
**Learning:** Hardcoded ARIA labels in mockups (like "출시 회의 일정 삭제") are often left intact during implementation, leading to incorrect screen reader announcements when different items are selected. In addition, action buttons that depend on selection state often lack correct visual and functional disabled states.
**Action:** When implementing detail views or sidebars, always replace hardcoded mockup ARIA labels with dynamic data (e.g. `${event.title} 삭제`), and ensure action buttons are explicitly disabled (both functionally via `disabled` and visually via `opacity-50 cursor-not-allowed`) when their prerequisites (like a selected item or specific properties like location) are unmet.

## 2026-06-25 - Accessible Dynamic Empty States in Dashboards
**Learning:** For dynamic, client-side rendered UI components (like dashboard panels), rendering an empty state message (like "대기 작업이 없습니다.") in a standard `div` will not be announced by screen readers when the state suddenly transitions from loading to empty.
**Action:** When modifying dynamic empty states that update asynchronously, ensure their container has `role="status"` and `aria-live="polite"` so screen readers are actively notified of the content change without aggressive interruption.

Extend the empty-state tests with live-region assertions before merging.

frontend/src/app/page.test.tsx#L476-L494 covers the three WorkspaceHome empty states but checks only their text. frontend/src/components/SearchLayout.test.tsx does not cover the empty search-result branch. Add assertions that all four states use role="status" and aria-live="polite".

In `@frontend/src/components/SearchLayout.tsx` at line 620, Extend
frontend/src/app/page.test.tsx at lines 476-494 to assert role="status" and
aria-live="polite" for all three WorkspaceHome empty states, and add coverage in
frontend/src/components/SearchLayout.test.tsx for the empty search-result branch
at SearchLayout.tsx lines 620-620 with the same assertions. The component sites
in frontend/src/components/WorkspaceHome.tsx lines 425-425, 454-454, and
555-555, and frontend/src/components/SearchLayout.tsx lines 620-620, already
provide the live-region attributes and require no direct changes.
