# TASK-043: Empty 즐겨찾기 tab offered 로그아웃 instead of a way back to 전체 저장소

Status: implemented; all required checks pass; live-confirmed on the human product owner's device
Owner: Claude
Reviewer: Codex

## Outcome

Live bug report: "현재 화면 즐겨찾기가 안되어있는데 로그아웃할거냐는 버튼이 왜 있지?" (the current
screen has nothing favorited, so why is there a button asking whether to log out?). Confirmed on
screen: the 즐겨찾기 tab, with zero starred repositories, showed "즐겨찾기한 저장소가 없습니다." and
directly below it a green primary button labeled "로그아웃" — logging out was presented as the answer
to "you have nothing starred," which makes no sense and is a jarring, semi-destructive-looking action
to put in front of a user who just wants to go star something.

Root cause: `RepositoryListScreen`'s `RepositoryListUiState.Empty` branch renders both of its two very
different cases — "즐겨찾기 has nothing starred yet" (fixable by visiting the other tab, right above
this message) and "the account itself has zero repositories" (a genuine dead end where logout really
is the only remaining action) — through the same `MessageState` call, which requires exactly one
mandatory action/label pair. The FAVORITES-mode branch reused `onLogout`/"로그아웃" from the ALL-mode
branch below it instead of getting its own action wired up.

## Scope

- Included: `feature/repositories/RepositoryListScreen.kt`'s `RepositoryListUiState.Empty` branch —
  split into two calls to `MessageState`, one per mode. FAVORITES-mode now uses
  `onShowAllRepositories` (already in scope at this call site) with a new
  `repositories_favorites_empty_action` ("전체 저장소 보기") label instead of `onLogout`/"로그아웃".
  ALL-mode (genuinely zero repositories on the account) is unchanged.
- Excluded: `MessageState` itself (still single-action by design; not worth generalizing for one call
  site). `RepositoryListViewModel` — this is a pure presentation fix, the `Empty` state's `mode` field
  it reads already existed.

## Acceptance criteria

- [x] 즐겨찾기 tab with zero starred repositories shows a button that reads "전체 저장소 보기", not
      "로그아웃".
- [x] Tapping it switches to the 전체 저장소 tab (reuses the same `onShowAllRepositories` the tab row
      itself already calls).
- [x] The genuinely-empty-account case (전체 저장소 tab, zero repositories at all) is unchanged and
      still offers 로그아웃.
- [x] Build, unit tests, and lint pass.
- [x] Live-confirmed on the human product owner's device: emptied 즐겨찾기 (repository had been
      unstarred since the last check), confirmed the button now reads "전체 저장소 보기", tapped it,
      confirmed it switches to 전체 저장소 and shows the full repository list.

## Required checks

```text
./gradlew compileDebugKotlin compileDebugUnitTestKotlin testDebugUnitTest assembleDebug lintDebug
```

## Evidence

- `feature/repositories/RepositoryListScreen.kt`: `RepositoryListUiState.Empty` branch now has two
  `MessageState` calls (FAVORITES vs. everything else) instead of one shared call with a hardcoded
  logout action.
- `strings_repositories.xml`: new `repositories_favorites_empty_action` = "전체 저장소 보기".
- `./gradlew compileDebugKotlin compileDebugUnitTestKotlin testDebugUnitTest assembleDebug lintDebug`:
  BUILD SUCCESSFUL, all unit tests passing unmodified (no test exercised this exact button label), 0
  lint errors.
- Live device: installed over wireless `adb`. 즐겨찾기 tab (currently empty — a previously-starred
  repository had been unstarred since TASK-041's verification) showed "전체 저장소 보기" (screenshot);
  tapped it and confirmed it lands on 전체 저장소 with the full list visible (screenshot).
