Walkthrough

The application now opens a detail screen for an existing late-study application. The screen displays application details and dates, and supports cancellation through a new DELETE request. Cancellation returns a result marker that clears the saved application.

Layer / File(s) Summary
Cancellation request path
network/src/main/kotlin/team/aliens/dms/android/network/latestudy/..., data/src/main/kotlin/team/aliens/dms/android/data/latestudy/repository/*

Adds optional application detail fields and loading, empty, error, and success states. The screen displays application details and dates, and offers cancellation for pending applications. Selectable dates in adjacent calendar months can also be enabled.

Adds the detail destination and routes existing applications to it. After cancellation, the application screen clears the saved late-study application when it receives the cancellation result marker.

Merge Risk: Low · previous review 1ff8c

A narrow cancellation timing race can restore a cancelled PENDING application until a later refresh. Fix the stale response handling before merging; the reason counter is a minor display issue.

Explanation

The title "🔀 :: (#996) 새벽 자습 신청 상세 화면 구현" translates to "Implement early-morning self-study application detail screen." The changeset adds LateStudyDetailScreen, LateStudyDetailRoute, LateStudyDetailViewModel, and navigation wiring for viewing an application's details and dates. This matches the main change. The emoji prefix, the "::" separator, and the PR number add noise, but the core message is accurate and specific.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 28 functions across 16 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Share the result key and cancellation marker between DmsApp and ApplicationScreen.

The producer and the consumer of this result use duplicated string literals:

  • DmsApp writes "late_study_application_result" and "late_study_application_cancelled" as inline literals.
  • ApplicationScreen reads the same key as an inline literal. It also keeps the marker in a private LATE_STUDY_APPLICATION_CANCELLED_RESULT constant.

A typo in one of these literals causes no compile error. The cancellation then does not clear the saved application, and the card keeps its stale PENDING state.

Expose the key and the marker as public constants in the feature module. Use them in both places.

Minor · Functional Correctness · Quick win

Compute the reason counter from the real reason, not the placeholder.

Line 202 passes application.reason.orUnavailable() to DetailReasonSection. When reason is null or blank, the placeholder "확인할 수 없어요" reaches reason.length. The counter then shows a non-zero value such as 8/200 for an application with no reason.

Pass the raw String? and apply the placeholder only to the displayed text.

Proposed fix
-                DetailReasonSection(reason = application.reason.orUnavailable())
+                DetailReasonSection(reason = application.reason)
-private fun DetailReasonSection(reason: String) {
+private fun DetailReasonSection(reason: String?) {
-                text = "${reason.length}/200",
+                text = "${reason.orEmpty().length}/200",
-            text = reason,
+            text = reason.orUnavailable(),

Run the late-study status write on the main dispatcher so it cannot interleave with the cancellation clear.

The status fetch from init runs on Dispatchers.IO, but clearLateStudyApplication() runs on the main thread from the result observer. A @Volatile version check on the IO thread does not close the window. The check, the SharedPreferences write, and the state write can still run after the clear has started, so the cancelled PENDING application can be restored. Running the handler on the main thread serializes it with the clear. fetchAppliedRemainsOption() already uses this pattern.

Trigger: the init GET is still pending when the user opens the detail screen and cancellation succeeds. The stale response restores the PENDING card and the persisted application for the current session.
