[Feat/#64] 열린피드백 질문 작성/전송 확인/완료 토스트 구현

[jjunh33]

#️⃣연관된 이슈

• Closes 열린피드백 질문 작성/전송 확인/완료 토스트 구현 #64

🎯 해결하려는 문제가 무엇인가요?

열린피드백 목록의 "피드백 작성" 버튼에 실제 동작이 연결돼 있지 않았고, 피드백을 새로 작성해서 보내는 화면 자체가 없었다.

❓ 왜 해결해야 하나요?

Figma에 피드백 질문 작성 화면·전송 확인 모달·완료 토스트가 모두 정의돼 있는데 코드에는 목록 화면만 있어서, 사용자가 실제로 피드백을 남길 방법이 없었다.

⭐ 어떻게 해결했나요?

• /feedbacks/new 화면을 새로 만들었다 — 텍스트어리아 입력(빈 내용이면 제출 버튼 비활성화), 제출 시 공용 ConfirmModal(행사 신청 확인 모달과 동일 컴포넌트)로 확인을 받는다.
• 확인 모달에서 "보내기"를 누르면 열린피드백 목록(/feedbacks)으로 이동하면서 navigate state로 신호를 넘기고, 목록 화면이 그 신호를 받아 "피드백을 보냈어요." 토스트를 약 3초간 띄운다. 새로고침해도 재노출되지 않도록 받는 즉시 history state를 비운다.
• ScreenToast가 기존엔 실패(negative) 전용으로 하드코딩돼 있던 걸 variant prop으로 일반화해서 성공(positive) 토스트도 지원하게 했다 — WDS 기본 체크 아이콘이 Figma와 이미 일치해서 별도 오버라이드는 없다.
• 목록 화면의 "피드백 작성" 플로팅 버튼에 실제 onClick 이동을 연결했다(이전엔 동작 없는 상태였음).

🧩 이 PR의 한계 & 트레이드오프

• 실제 제출 API가 없어서, 확인 모달에서 "보내기"를 누르면 목업으로 바로 목록 화면 이동 + 토스트만 띄운다.
• /figma-check로 재검증한 결과, 확인 모달의 딤(배경 어둡기)이 Figma 원본 프레임에서는 40%인데 이 파일의 다른 확인 모달 9곳 중 8곳은 70%였다. 다수 값(70%, 기존 ConfirmModal 값)을 그대로 유지했고, 40%는 Figma 쪽 예외로 보고 코드는 고치지 않았다.

⛓️ 기존 기능에 미치는 영향

• ScreenToast는 기존 실패 토스트(EventsApplicationScreen)에서 이미 쓰고 있는데, variant prop을 추가하되 기본값을 "negative"로 둬서 기존 호출부는 변경 없이 그대로 동작한다.
• ConfirmModal은 기존 행사 신청 흐름과 완전히 동일한 컴포넌트를 그대로 재사용했다(수정 없음).

🔀 Edge Case & 실패 시나리오

• 내용이 빈 상태에서는 "피드백 보내기" 버튼이 비활성화돼 제출 자체가 안 된다.
• 확인 모달에서 "수정"을 누르면 작성 중이던 내용을 유지한 채 모달만 닫힌다.
• 토스트가 뜬 상태에서 새로고침해도 재노출되지 않는다(navigate state를 받는 즉시 비움).

📋 검토한 대안과 선택 이유

• 확인 모달을 새로 만들지 않고 기존 ConfirmModal(행사 신청 흐름에서 이미 쓰던 공용 컴포넌트)을 그대로 재사용했다 — 타이틀/설명/버튼 라벨만 다르고 구조는 완전히 동일해서 새로 만들 이유가 없었다.
• 완료 토스트도 새 컴포넌트 대신 기존 ScreenToast를 variant prop으로 확장해서 재사용했다.

💬 리뷰 포인트

• [c] 확인 모달 딤 불투명도(70% 유지, Figma 예외로 판단)에 이견 있으면 알려주세요.
• [a] 완료 토스트를 navigate state로 신호를 넘기는 방식이 이후 다른 화면에서도 재사용하기 적절한 패턴인지 봐주시면 좋겠습니다.

Summary by CodeRabbit

• New Features
  • Added a feedback-writing screen accessible from the feedback list. Feedback is limited to 500 characters, and the submit button is enabled when the entry contains non-whitespace text.
  • Submitting opens a confirmation dialog. After confirmation, the feedback list displays a success toast; canceling closes the dialog without submitting.
  • Added a back button that returns to the previous screen, or to the feedback list when no previous screen is available.
  • Positive and negative toasts are supported, with negative toasts retaining their custom styling.

📝 Walkthrough

Walkthrough

The feedback list now opens a feedback-entry screen. Users can enter feedback, confirm submission, and return to the list, where a positive toast appears.

Changes

Feedback submission

Layer / File(s)	Summary
Feedback entry and confirmation src/features/feedbacks/FeedbacksNewScreen.tsx, src/app/router.tsx	Adds the /feedbacks/new route and screen. The screen limits input to 500 characters, disables submission for empty trimmed content, and uses a confirmation modal before navigating back to the list with submission state.
Feedback completion notification src/features/feedbacks/FeedbacksListScreen.tsx, src/components/ui/ScreenToast.tsx	The list opens the entry screen from its feedback button. When submission state is present, the list clears that state and displays a positive toast. ScreenToast now supports positive and negative variants.

Merge Risk: ⚪ Minimal · up to 028be

The change adds a feedback-entry flow and completion notification; no concrete user-impacting defect is established, so it appears ready for normal checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 028be

The new screen can tell users their feedback was sent when it was not saved or delivered. The observed flow stays within the browser and does not expose a privileged service or another user’s data.

Retained concerns

• Medium · architecture · observed: Confirming feedback discards the draft and reports it as sent without a submission attempt or acknowledgment. The completion signal represents a navigation event, not delivered feedback.

Security review details

Security Blast Radius

• inferred — The observed effect of a forged completion flag is limited to the current browser’s toast. The inspected path does not grant authority or write to a shared data store.

Trust Boundaries and Controls

• observed — Nonblank input and a confirmation modal control the ordinary UI path, but the list accepts a truthy feedbackSent history-state value without validating a submission result.

Resilience and Maintainability Implications

• observed — Replacing the history state addresses immediate refresh replay, but it cannot recover the discarded draft or establish delivery after confirmation.

Hardening Proposals

• proposed — Until submission exists, identify the flow as a preview rather than reporting delivery. When submission is added, emit the success signal only after an acknowledged result and retain the draft on failure.
