ExportModal.tsx의 '접근 관리' 버튼에 native `disabled` 속성이 적용되어 있어 화면 판독기(Screen Reader)와 키보드 탐색(Tab) 사용자가 버튼의 존재와 그 이유(`aria-describedby`)를 인지할 수 없는 문제를 해결했습니다.
Native `disabled` 대신 `aria-disabled="true"`를 사용하고, `onClick` 핸들러에서 `e.preventDefault()`를 호출하여 액션을 안전하게 차단했습니다. 또한 시각적 비활성화 상태를 유지하기 위해 CSS(opacity: 0.5, cursor: not-allowed)를 추가하고, 이에 대한 테스트 코드와 Palette 일지를 갱신했습니다.

 ## 2026-07-30 - Add window.confirm for destructive actions

+**Learning:** Native `disabled` attributes on buttons remove them from the tab order, preventing screen reader users from discovering them and hearing their `aria-describedby` helper text explaining *why* they are disabled.
+**Action:** When a disabled button has important explanatory context (like requiring project permissions), use `aria-disabled="true"` with custom styling (opacity and cursor) and manually prevent action (e.g., `e.preventDefault()`) instead of the native `disabled` attribute to keep it discoverable via keyboard navigation.

 ## 2026-06-21 - Form Input Keyboard Navigation
 **Learning:** Standalone inputs without wrapping `<form>` elements inherently lack keyboard submission support, forcing users to switch from keyboard to mouse just to complete simple forms. Furthermore, modal dialogues holding inputs trap keyboard users unless explicit cancelation escapes are implemented.
 **Action:** When implementing inputs outside of standard `<form>` contexts or within custom modals, explicitly add `onKeyDown` handlers to support `Enter` for submission and `Escape` for cancelation.
 ## 2024-06-23 - [Safe Scope UX Tooltips]
-**Learning:** Adding helpful `title` tooltips to text indicating truncation (e.g., "... N more") significantly improves usability for screen readers and confused users without changing visual layouts. More importantly, when working in a repository with aggressive penetration testing (like STRIX), UX changes must avoid touching components that handle sensitive inputs (like `App.tsx` dealing with DSNs). If an agent modifies a vulnerable file, even just for a UX change, the CI will run the pen-test against that file and block the PR.

 ## Unreleased
+- [FE] ♿ **내보내기 접근 관리 안내 유지**: 사용할 수 없는 `접근 관리` 버튼을 포커스 순서에 남기면서 `aria-disabled`와 연결된 설명을 노출하고, activation은 취소하도록 회귀 계약을 추가했습니다.
 - [BE] 🔒 **Cryptography 50+ 보안 경계 갱신**: `pyproject.toml`과 두 hash-locked 요구사항 파일을 동일한 Cryptography 50+ 해석으로 정합화하여 PKCS#7 오류·타이밍 구분으로 인한 CVE-2026-69247 완화를 실제 설치·검증 경로에 반영했습니다.
 - [FE] ⚡ **검색 노드 참조 안정화 및 순차 스냅샷 폴링**: 같은 정규화 검색어와 원본 테이블 데이터에는 장식된 `node.data` 참조를 재사용하여 드래그 중 불필요한 하위 렌더링과 할당을 줄입니다. 스냅샷 폴링은 이전 요청이 끝난 뒤에만 다음 요청을 예약하며, 선택 변경·언마운트 후 도착한 오래된 성공 또는 실패 응답을 무시합니다.
 - [BE] 🔒 **공유 export 전 경로 redaction**: 공개 share의 SQL / index-design / reversing-spec export에서 코멘트·`example_value`를 제거합니다. 단위 테스트로 누출을 차단합니다.

-- [FE] ♿ **내보내기 접근 관리 안내 유지**: 사용할 수 없는 `접근 관리` 버튼을 포커스 순서에 남기면서 `aria-disabled`와 연결된 설명을 노출하고, activation은 취소하도록 회귀 계약을 추가했습니다.
 - [BE] 🔒 **Cryptography 50+ 보안 경계 갱신**: `pyproject.toml`과 두 hash-locked 요구사항 파일을 동일한 Cryptography 50+ 해석으로 정합화하여 PKCS#7 오류·타이밍 구분으로 인한 CVE-2026-69247 완화를 실제 설치·검증 경로에 반영했습니다.
 - [FE] ⚡ **검색 노드 참조 안정화 및 순차 스냅샷 폴링**: 같은 정규화 검색어와 원본 테이블 데이터에는 장식된 `node.data` 참조를 재사용하여 드래그 중 불필요한 하위 렌더링과 할당을 줄입니다. 스냅샷 폴링은 이전 요청이 끝난 뒤에만 다음 요청을 예약하며, 선택 변경·언마운트 후 도착한 오래된 성공 또는 실패 응답을 무시합니다.
 - [BE] 🔒 **공유 export 전 경로 redaction**: 공개 share의 SQL / index-design / reversing-spec export에서 코멘트·`example_value`를 제거합니다. 단위 테스트로 누출을 차단합니다.

Subject: [PATCH 13/16] chore(ui): keep ExportModal accessibility decision
 local

Restore .jules/palette.md byte-for-byte from protected main so this one ExportModal interaction choice does not become repository-wide doctrine. Preserve the existing component, stylesheet, and regression delta as normal descendant history.

 ## 2026-07-30 - Add window.confirm for destructive actions
 **Learning:** Destructive actions like deleting groups and edge relationships previously occurred immediately without user confirmation.
 **Action:** Always wrap delete operations with window.confirm() dialogs and ensure corresponding tests successfully mock window.confirm.

-## 2026-08-01 - Focusable aria-disabled buttons for screen readers
-**Learning:** Native `disabled` attributes on buttons remove them from the tab order, preventing screen reader users from discovering them and hearing their `aria-describedby` helper text explaining *why* they are disabled.
-**Action:** When a disabled button has important explanatory context (like requiring project permissions), use `aria-disabled="true"` with custom styling (opacity and cursor) and manually prevent action (e.g., `e.preventDefault()`) instead of the native `disabled` attribute to keep it discoverable via keyboard navigation.
