  • exact head: 744e19d232d0299696d5a515a417443665ae5248
  • lifecycle: Draft / title-only accessibility RED remains / persistent-context source GREEN + browser evidence pending

Current RED

The product source still uses title / data-i18n-title="externalLink" as the only new-window warning for target="_blank" links. The current regression likewise proves title tokens exist rather than proving persistent, programmatically associated context in the accessibility tree.

This is not complete buyer-facing accessibility. A tooltip is supplemental; the link needs a programmatically associated description that does not depend on hover. The WHATWG HTML button/link semantics and accessibility-tree behavior must be verified in the actual browser, not inferred from source strings.

Required source GREEN

  1. Introduce one reusable runtime/component path for external-link context instead of duplicating warning text in every anchor.
  2. Preserve a11y(external-links): keep localized tooltip supplemental to persistent context #213's valid localized supplemental tooltip behavior, but add persistent programmatic context to every target="_blank" link—e.g. one localized description node referenced via aria-describedby, or an equivalent accessible-content contract.
  3. Keep rel="noopener noreferrer" on every blank-target link.
  4. Locale changes must update the existing context node rather than append duplicate announcements.
  5. Rewrite/extend the regression so title-only markup fails and the reusable description contract is required. Static tests are source RED/GREEN evidence only, not browser accessibility-tree evidence.
  6. Preserve layout and focus geometry at desktop, intermediate, and mobile widths.

The current runtime is KO/EN-only and keeps translations in i18n.js; that remains migration debt rather than the fleet target translation-ledger architecture. Do not silently expand this PR into another permanent browser-bundle catalog. The longer-term locale boundary must cover KO/EN/JA/ZH/VI/ES/DE/FR through the canonical versioned resource path.

Intervening-delta repair

A later concurrent descendant again reintroduced branch-local .Jules/palette.md doctrine describing the title-only pattern as repository-wide accessibility guidance. History was retained. Normal descendant 744e19d232d0299696d5a515a417443665ae5248 restores exact protected blob 8a7cf4c6c21140f209ac1c2a5b6347a5b65ac9fc; generated doctrine is outside the effective PR delta. No force push or destructive rebase was used.

Sibling #213 is now Draft at aa1dde72f5091ea2c5e78ebc006776f0c7cf7e7d. It retains the localized-title experiment and protected .Jules/palette.md. Do not close it merely for overlap. This lane may supersede #213 only after its valid localized tooltip semantic is fully inherited together with the stronger persistent-context contract and exact-head browser evidence.

Browser Delivery Gate

Before Ready: keyboard-focus the affected links; inspect computed accessible name/description; switch every currently supported locale and prove one announcement per link; verify desktop/intermediate/mobile layout with no overflow/focus clipping; then capture current-head screenshot/E2E evidence. Static HTML/Python checks alone are insufficient.

Current gate: 의도성 PASS / 기능 완전성 FAIL / 콘텐츠 적합성 PASS / 복원력 FAIL / 증거성 FAIL / 고유성 N/A.

Fresh exact-head hosted runs are required on unchanged 744e19d2...; predecessor results do not transfer. No GitHub Pages publication or browser acceptance is claimed. No self-approval, gate weakening, source-neutral retrigger, generated doctrine, force push, or destructive rebase.

externalLink 번역을 추가하고 외부 링크의 title 속성을 언어별로 갱신하도록 변경했습니다. 모든 target="_blank" 링크에 번역 속성과 기본 제목을 추가했습니다. 관련 접근성 검사를 추가했습니다.

Changes

외부 링크 제목 지원

Layer / File(s) Summary
다국어 제목 번역 및 적용
i18n.js
한국어와 영어 사전에 externalLink 번역을 추가했습니다. setLanguagedata-i18n-title의 값을 해당 요소의 title 속성에 적용합니다.
외부 링크 제목 속성 및 검사
index.html, tests/test_a11y_ux.py
모든 target="_blank" 외부 링크에 data-i18n-title="externalLink"과 기본 title을 추가했습니다. 테스트는 필수 제목 속성과 번역 설정을 검사합니다.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to eca21

외부 링크의 새 창 안내 제목과 언어별 갱신 기능이 추가되었습니다. 현재 검사는 영문 제목이나 실제 title 속성이 없어도 통과할 수 있어, 이후 변경에서 접근성 안내가 누락되는 회귀를 잡지 못할 수 있습니다.

영문 번역과 실제 title 속성을 함께 검증하세요.

현재 테스트는 한국어 externalLink 번역만 확인합니다. 영문 키가 삭제되어 영어 전환 후 제목이 갱신되지 않아도 테스트가 통과합니다. 또한 assert "title" in linedata-i18n-title 문자열만으로 통과하므로 실제 title 속성을 검증하지 않습니다. 영문 번역을 추가로 확인하고 title="..." 값을 정확히 검사하거나 HTML 파서로 속성을 확인하세요.
