Draft. protected base develop@2c328875e00e86537df3e965170be80532571cad, exact head da680686b2e3bde8450f73d5985ff82ae4cfae62입니다. Base 대비 effective diff는 package.json과 tests/e2e/csv-import-focus.spec.js 두 파일뿐이며 production app.js와 .jules/palette.md는 protected exact blob으로 ordinary-forward 복원했습니다.

왜 production 수리를 제거했는가

원래 PR은 CSV 가져오기 성공 후 renderAll()이 trigger를 파괴해 <body>로 포커스를 잃는다고 가정하고 requestAnimationFrame(...focus())를 추가했습니다. 그러나 production source를 바꾸지 않은 test-only counterfactual #700 exact head b108c65a7f9b2e96e2a082f0c545b6d927051bf7에서 hosted Server Tests 34710353436의 cloud-e2e job 103597882556이 GREEN이었습니다. 즉 protected behavior가 성공 경로의 trigger focus를 이미 보존하므로 그 production delta는 causal fix가 아니었습니다.

반대로 CodeRabbit review가 지적한 empty-state import 실패 경로를 browser contract로 추가하자, 이전 production override가 있던 exact head 13ab8a4f8d64f26000ce203c1dbb20b2b6a372a9의 hosted cloud-e2e job 103597965800이 실제 RED가 됐습니다. 실패는 CSV 가져오기에 실패했습니다: toast 이후 empty-state CSV 가져오기 버튼이 focused 상태가 아니라는 exact assertion입니다. 이 RED를 근거로 무조건 footer #import-csv를 focus하던 override를 제거했습니다.

current acceptance

현재 PR은 제품 동작을 바꾸지 않고 두 browser invariant를 고정합니다.

  • 실제 제품이 내보낸 seeded CSV를 다시 가져온 성공 경로에서 footer #import-csv focus가 유지된다.
  • empty-state에서 invalid CSV import가 실패하면 사용자가 눌렀던 empty-state CSV 가져오기 trigger에 focus가 남는다.

package.json은 이 regression들을 기존 hosted test:e2e:cloud lane에 실제 포함시키기 위한 변경입니다. 새 exact head의 hosted browser GREEN, applicable security/SAST, 중앙 CodeQL settlement, current-head 독립 review가 모두 성립하기 전에는 Ready/merge하지 않습니다.

Delivery Gate: 의도성 PASS; 콘텐츠 적합성 PASS; 기능 완전성 PENDING; 복원력 PENDING; 증거성 PENDING; 고유성 N/A.

No force push/rebase, self-approval, unsupported WCAG/performance claim, predecessor GREEN 전용, source-neutral retrigger, synthetic status, gate weakening.

When importing a CSV, the DOM is completely re-rendered, which
causes the browser to reset focus to the `<body>` element. This
breaks keyboard navigation flow for screen-reader and keyboard
users.

This change uses `requestAnimationFrame` to explicitly set focus
back to the "CSV 가져오기" (Import CSV) button after the
asynchronous import operation and DOM updates complete.

OpenCode Review Overview

Coverage evidence did not pass, so approval is blocked. The formal pull-request review is the source-backed diff review, not this status comment.

When importing a CSV, the DOM is completely re-rendered, which
causes the browser to reset focus to the `<body>` element. This
breaks keyboard navigation flow for screen-reader and keyboard
users.

This change uses `requestAnimationFrame` and a dynamic lookup
to safely restore focus to the "CSV 가져오기" (Import CSV) button

@jules owner-path acceptance를 갱신합니다. Test-only counterfactual #700 exact head b108c65a7f9b2e96e2a082f0c545b6d927051bf7는 protected develop@2c328875... production source 그대로인 상태에서 hosted Server Tests 34710353436의 cloud-e2e job 103597882556이 GREEN이었습니다. 즉 성공한 CSV import 뒤 #import-csv focus 보존은 기존 protected behavior가 이미 만족해 현재 app.js의 requestAnimationFrame(...focus())를 causal fix로 정당화하지 못합니다.

또 current branch에는 empty-state trigger에서 import가 실패했을 때 같은 trigger에 focus가 남아야 한다는 browser regression을 추가했습니다. 현 구현처럼 무조건 footer #import-csv를 focus하면 이 경로를 깨뜨릴 가능성이 있습니다.

따라서 protected base exact blob을 기준으로 app.js의 이 PR production focus delta와 .jules/palette.md의 feature-local 항목을 둘 다 ordinary-forward 복원해 주세요. tests/e2e/csv-import-focus.spec.js와 이를 hosted test:e2e:cloud에 포함한 package.json은 보존하십시오. force push/rebase 없이 descendant commit으로 처리하고 새 exact head를 남겨 주세요.

@coderabbitai review

Current exact head da680686b2e3bde8450f73d5985ff82ae4cfae62만 대상으로 다시 검토해 주세요. Production app.js와 .jules/palette.md는 protected base로 복원됐고 effective diff는 package.json + tests/e2e/csv-import-focus.spec.js뿐입니다. 특히 (1) test가 실제 product export/import flow를 검증하는지, (2) empty-state failed import focus assertion이 browser/a11y 관점에서 타당한지, (3) hosted test:e2e:cloud wiring이 과도하거나 누락되지 않았는지 검토해 주세요. 이전 head의 release-note summary나 production fix 평가는 current-head verdict로 승계하지 마십시오.

@seonghobae 현재 exact head da680686b2e3bde8450f73d5985ff82ae4cfae62만 검토했습니다. Blocking finding은 없습니다.

  1. tests/e2e/csv-import-focus.spec.js는 실제 제품 흐름을 사용합니다. 테스트는 UI의 CSV 내보내기 버튼으로 다운로드를 만들고, UI의 CSV 가져오기 버튼과 native file chooser를 통해 그 파일을 다시 가져옵니다. 기존 데이터 교체 확인 dialog도 수락합니다. 성공 toast와 trigger focus를 확인합니다.

  2. Empty-state 실패 경로의 focus assertion은 타당합니다. 테스트는 persisted empty state를 설정한 뒤 다시 로드하므로, 동적으로 생성되는 empty-state CSV 가져오기 버튼을 대상으로 합니다. 현재 handleCsvImport()은 실패 시 renderAll()을 호출하지 않습니다. 따라서 해당 버튼이 DOM에 남고 focus를 유지해야 합니다. role="status" toast도 focus를 가져가지 않습니다.

  3. test:e2e:cloud wiring은 적절합니다. hosted cloud-e2e job은 npm run test:e2e:cloud를 실행합니다. 이 명령은 이미 static UI E2E인 tests/e2e/toast-accessibility.spec.js를 포함합니다. csv-import-focus.spec.js 추가는 이 기존 범위와 일치합니다. 별도 browser 설치나 workflow 변경도 추가하지 않습니다.

이 검토는 정적 분석 결과입니다. 이 sandbox에서는 테스트를 실행하지 않았습니다.
