🎨 Palette: 필수 입력 필드 검증 피드백 개선

[seonghobae]

💡 What: 필수 입력 필드(target_bytes 및 batch_target_bytes)의 값을 비울 때 시각적 및 스크린 리더 피드백을 제공하도록 검증 로직을 개선했습니다.
🎯 Why: 사용자가 필수 필드를 비울 때 경고 없이 오류 상태가 해제되는 문제를 수정하여 폼 제출 전에 명확한 피드백을 제공하기 위함입니다.
♿ Accessibility: 필수 필드가 비어있을 때 aria-invalid="true"를 설정하여 스크린 리더 사용자에게 입력이 유효하지 않음을 명확하게 전달합니다.

📝 Walkthrough

Walkthrough

빈 target_bytes 및 batch_target_bytes 입력이 필수 입력 오류를 표시하고, 미리보기와 접근성 상태를 갱신하도록 변경했습니다. 관련 테스트도 새 검증 상태를 확인하도록 수정했습니다.

Merge Risk: 🔵 Low · up to 0efbe

Empty target-size inputs now show required-field feedback for single and batch uploads. The validation behavior is covered, but the changed preview styling lacks direct regression coverage, creating a bounded UI-feedback risk before merge.

추가한 미리보기 상태도 테스트하십시오.

현재 테스트는 오류 메시지, customValidity, aria-invalid만 확인합니다. 변경된 preview.style.color = ''와 preview.classList.add('required-star')는 확인하지 않습니다. 이 검사가 없으면 해당 상태 처리가 삭제되어도 테스트가 통과합니다. 두 핸들러에 다음 문자열 검사를 추가하십시오.

DESIGN ASSURANCE forward-only repair — live exact head a6aa18e8c90c7795c1b4b3103e332f16dbcdb96f, Draft.

The required-field feature adds required-star on empty input. Without removing it before later validation, empty→valid leaves stale presentation state. Earlier forward repairs established the cleanup and ordering assertion, but concurrent commit 9c1ddf28bd7086ec5e90917cd3b9c51dfd888896 explicitly removed both production cleanup lines and the matching test assertions while keeping the feature.

After re-fetching that exact parent, atomic forward commit a6aa18e8... restores both handlers and their ordering contract in one commit. It preserves the original feature delta and uses no force push or destructive rebase. No hosted RED/GREEN is claimed for this new head; only its newly generated exact-head workflows count.

Merge acceptance still requires terminal exact-head checks plus real-browser keyboard/pointer behavior, empty→valid→empty transitions, accessible error announcement/focus, submit/reload/race cleanup, responsive evidence and KO/EN/JA/ZH/VI/ES/DE/FR copy.

[google-labs-jules]

Design Assurance exact-head finding — 0efbe22b41b36ded41f3bbdb87b4db2cec67403b

The required-field feedback is a material form-state change, but its test parses source text rather than exercising the browser. Exact-head OpenCode, Noema and two CodeQL-compatibility jobs are terminal failures.

Moved to Draft. Owner acceptance requires real-browser initial/empty/invalid/valid correction, required-field announcement, preset→manual edit, submit blocking, focus retention, batch parity, server rejection/retry, responsive/zoom/touch evidence and ko/en/ja/zh/vi/es/de/fr screen-scoped copy. The CSS error class must also be removed or demonstrably overridden when the value becomes valid so stale presentation state cannot survive correction.

Understood. The required additions for real-browser testing across multiple states and full multi-language localization (ko/en/ja/zh/vi/es/de/fr) exceed the scope of a < 50 line micro-UX improvement. Acknowledging that this work is obsolete under the current constraints and stopping work on this task.

[seonghobae]

Verified successor consolidation, not a simple close. #54280762cf changes only saas_web.py, tests/test_empty_file_validation.py, and tests/test_empty_target_validation.py. Current convergence lane #5409183ad6 carries the same required-value production contract for both target inputs, the file-input required contract, and a strict superset of the focused regression coverage: file empty-state cleanup/feedback, initial native invalid handling, batch listener readiness, plus target stale .required-star cleanup and the empty-branch style.color, .required-star, custom-validity, and aria-invalid assertions.

A fresh read found that intervening #540 head 77d59e0 had accidentally weakened tests/test_empty_target_validation.py; that was repaired by ordinary descendant 9183ad6 before this retirement. No #542 semantic/test/fixture/contract evidence is being discarded. #540 remains Draft and must earn fresh exact-head CI/Security/SAST/fuzz/CodeQL, independent review, and real-browser accessibility evidence; no predecessor GREEN is transferred.
