Current exact state

Protected/base: main@8dc746920c12988f082e914879d95e13c9693535.
Current exact head: 7132575d1b776baa9993f432476a467d0e641934.
The PR is Draft. Current-head CI/security evidence does not inherit from predecessor heads.

User-visible contract

When project permissions make 접근 관리 unavailable, the control remains focusable with aria-disabled="true" and keeps aria-describedby="share-export-access-hint". Activation is explicitly prevented, so focusability exposes the reason without making the unavailable action executable.

W3C WAI-ARIA Authoring Practices explicitly treats disabled-control focusability as a design trade-off: native disabled controls normally leave the Tab sequence, while aria-disabled="true" can be appropriate when a disabled function needs to remain discoverable. The product-specific reason here is the adjacent permission guidance, not a repository-wide rule that every disabled button must remain focusable.

Authoritative reference: https://www.w3.org/WAI/ARIA/apg/practices/keyboard-interface/#focusabilityofdisabledcontrols

Repair evidence on this branch

  • frontend/src/components/modals/ExportModal.test.tsx now verifies aria-disabled, focusability, the description relationship, and a cancelable click whose default action is actually prevented.
  • Both CHANGELOG.md and frontend/CHANGELOG.md record the user-visible accessibility change.
  • The generated .jules/palette.md entry was removed by restoring the protected-base blob. A local product decision should not become an unconditional accessibility doctrine; the W3C guidance itself calls for context-sensitive conventions.

Delivery Gate

  • Intentionality: PASS — discoverability of the permission explanation is the reason for retaining focus.
  • Functional completeness: PASS at component-contract level — disabled state, focus and click prevention now have focused regression evidence.
  • Content fitness: PASS — helper text is product-specific and no template-only section was added.
  • Resilience: PARTIAL — hosted current-head tests are still non-terminal and real-browser keyboard/pointer behavior has not yet been re-proven on this head.
  • Evidence: PARTIAL — source/test/changelog and W3C rationale are present; current-head browser screenshot/accessibility-tree evidence remains pending.
  • Distinctiveness: N/A — this change does not alter visual/product identity.

Remain Draft until one unchanged exact head has terminal required checks plus current-head browser/keyboard evidence. Do not promote predecessor GREEN, self-approve, weaken gates, or force-update the branch.

- ExportModal 내 접근 관리 버튼의 `disabled` 속성을 `aria-disabled={true}`와 `onClick={(e) => e.preventDefault()}`로 대체하여 키보드 포커스 유지
- `exportModal__disabledHintButton` 클래스에 불투명도 및 커서 스타일을 수동으로 추가하여 시각적 피드백 유지
- ExportModal.test.tsx에서 `toBeDisabled` 검증을 `aria-disabled`와 포커스 확인으로 변경하여 접근성 검증 강화

Merge Risk: 🔵 Low · up to da9c7

The access-management hint button is now focusable while presented as unavailable, improving access to its hint. Click blocking is implemented but lacks direct regression coverage, and the accompanying accessibility guidance needs its required citation; these are bounded follow-ups.
