Current exact state

Protected/base: main@8103aad3582a024946b835d7eee858f65339a184.
Current exact head: f4df0a3f04334fd7654b11d19aa22e26b971ba9b.
This PR remains Draft.

Source GREEN now present

The earlier title-only implementation was a valid accessibility defect: keyboard, touch, and assistive-technology users could not depend on a hover tooltip to learn that a link opens a new browsing context.

The deterministic production-page RED added on predecessor d72897628bee1da73c0ed1cdd63ffa8500b75e9e requires every a[target="_blank"] in shipped index.html to reference a localized non-title common.newWindow description through aria-describedby.

Normal descendant f4df0a3f04334fd7654b11d19aa22e26b971ba9b implements that contract:

  • every shipped target="_blank" link references #new-window-desc;
  • #new-window-desc is visually hidden ordinary DOM content and is localized through the existing data-i18n="common.newWindow" path;
  • KO is 새 창에서 열림; EN is Opens in a new window;
  • the previous title/data-i18n-title mechanism was removed rather than kept as a second warning authority, avoiding two independently maintained descriptions;
  • destinations and rel="noopener noreferrer" remain unchanged;
  • test_i18n.html verifies both the production-page aria-describedby contract and KO/EN description switching.

The valid Devin/CodeRabbit findings are therefore source-addressed on this exact head. Their threads stay open for now because the promotion contract also requires current-head browser/keyboard/accessibility evidence, not just DOM/source evidence.

Evidence boundary

Source/contract evidence: GREEN on f4df0a3....
Hosted exact-head evidence is still non-terminal: SAST run 33841032683 is pending and Security Scan 33841032688 is queued.

Still required before Ready/merge:

  • exact-head browser harness completion;
  • keyboard navigation and focus behavior with the external links;
  • accessibility-tree confirmation that the localized description is exposed in KO and EN;
  • zero still-valid unresolved review findings after that evidence is attached;
  • terminal required CI/security evidence on the unchanged head.

Because this repository publishes GitHub Pages from integrated main, a PR-head source/browser GREEN is not publication evidence. Do not claim the site is published until the final integrated main is actually served.

Delivery Gate

  • Intent: PASS — the new-window warning has a concrete accessibility purpose.
  • Functional completeness: PASS at source/DOM-contract level; browser/AT completion remains pending.
  • Content fit: PASS — one shared localized description; no template-only UI was added.
  • Resilience: PARTIAL — KO/EN source switching is covered; keyboard/touch/AT current-head evidence is pending.
  • Evidence: PARTIAL — deterministic source contract is GREEN; hosted/browser evidence is not terminal.
  • Uniqueness: N/A — behavioral accessibility repair, not a visual identity change.

Remain Draft. No force rewrite, self-approval, gate weakening, predecessor-GREEN transfer, or premature GitHub Pages publication claim.

Merge Risk: 🔵 Low · up to dfe5a

The change adds localized new-window tooltips to external links, but screen reader users may not consistently receive that warning when it is provided only as a title attribute. This is a bounded accessibility gap rather than a runtime or data-integrity risk.

🟡 New-window warning remains inaccessible

Every external link puts its warning only in title, which touch and keyboard users cannot reliably access. Screen readers also omit it inconsistently.

Prompt for agents
The new-window notice is currently supplied only through title attributes on every target="_blank" link in index.html. Native title tooltips do not provide a dependable warning to keyboard, touch, or screen-reader users. Replace or supplement this mechanism with content in the link's accessible name, such as localized visually hidden text, while preserving the visible design and both Korean and English language switching. Apply the same pattern consistently to every external link and add browser-harness coverage for switching the notice between languages.

유효 finding으로 재검증했습니다. exact head 39a055ed6e5b358f5795ec18eb25244185898c25은 Draft이며 아직 source GREEN이 아닙니다. d72897628bee1da73c0ed1cdd63ffa8500b75e9e에서 test_i18n.html이 실제 index.html을 fetch/parse해 모든 target="_blank" 링크가 aria-describedby로 현지화된 common.newWindow 설명을 참조해야 한다는 RED를 추가했습니다. 현재 title-only markup은 이 계약을 실패해야 합니다. W3C G200/G201은 새 창 사전 경고를 advisory good practice로 설명하고, WAI-ARIA APG는 title이 pointer-hover 없이는 잘 발견되지 않는다고 명시합니다. 최소 GREEN은 KO/EN 설명을 ordinary accessible semantics에 넣고 모든 외부 링크에서 참조시키는 것입니다. exact-head keyboard/touch/accessibility-tree/browser evidence 전에는 이 thread를 resolve하지 않겠습니다.

Understood. The implementation has been corrected to use aria-describedby linking to a single localized visually-hidden text span with the common.newWindow warning. I also confirmed that the custom .visually-hidden class is now placed into styles.css without breaking the strict CSP.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

title만으로 새 창 안내를 구현하지 마세요.

title은 브라우저 툴팁을 제공하지만, 모든 screen reader와 browser 조합에서 접근 가능한 설명으로 일관되게 노출되지 않습니다. 따라서 스크린 리더 사용자는 링크가 새 창 또는 탭을 여는 사실을 듣지 못할 수 있습니다. 현지화된 숨김 설명을 추가하고 각 링크에 aria-describedby를 연결하세요. title은 툴팁용으로 유지할 수 있습니다.

동일하게 유효 finding입니다. title은 브라우저 툴팁용 보조 정보로 유지할 수 있지만 접근 가능한 새 창 경고의 단독 authority로 쓰지 않습니다. current-head RED는 shipped index.html 전체의 target="_blank" 링크를 검사해 현지화된 non-title description 참조를 요구하도록 추가했고, .Jules/palette.md도 이 좁은 규칙으로 수정했습니다. 현재 source는 아직 RED이므로 thread는 열린 상태로 유지합니다. GREEN 후에는 KO/EN 언어 전환과 실제 keyboard/focus/accessibility-tree evidence를 같은 exact head에서 다시 확인하겠습니다.

@seonghobae, 확인했습니다. Finding은 유효하며 열린 상태로 유지합니다.

title은 브라우저 툴팁용 보조 정보로 유지할 수 있습니다. 각 target="_blank" 링크는 현지화된 non-title description을 aria-describedby로 참조해야 합니다. GREEN 변경 후, 동일 HEAD에서 KO/EN 전환과 keyboard, focus, accessibility tree 증거를 확인하겠습니다.

Learning: For `index.html`, a `title` attribute is supplementary tooltip text and must not be the only accessibility warning for links using `target="_blank"`. Each shipped external link must reference a localized non-title “opens in a new window” description through `aria-describedby`. Verify the behavior after changes for both Korean and English language states, keyboard and focus operation, and the accessibility tree on the exact commit under review.

Acknowledged. The index.html references have been properly updated to aria-describedby, and the supplemental tooltip functionality in i18n.js has been removed in favor of this single authoritative accessible warning element. .Jules/palette.md and CHANGELOG.md have been updated accordingly, and tests ensure the aria-describedby contract.
