- Line 23: Update the enum conversion expressions in the migration’s ALTER
COLUMN statements for collaborator role fields to map existing Viewer and Active
values to approved replacement enum values before casting to
CollaboratorRole_new and the corresponding replacement type. Preserve direct
casting for values already present in the new enums, and apply the same mapping
wherever these conversions occur.
- Around line 86-92: Update the integrate_mandeuldang_problem migration to
preserve rows from mandeuldang_approval_request, mandeuldang_problem, and
mandeuldang_sample before dropping those tables. Copy or transform legacy
problems into the retained problem records, establish an explicit old-to-new ID
mapping, and rewrite every retained child problem_id through that mapping before
adding foreign keys or dropping the legacy tables; ensure unmappable references
are handled without creating incorrect associations.
In `@apps/backend/prisma/schema.prisma`:
- Around line 256-259: Update all consumers of the generated Problem type for
nullable description, inputDescription, outputDescription, and hint fields,
handling null values without type errors while preserving existing behavior for
populated values. Alternatively, defer the schema nullability change until those
consumers are compatible.

Enforce a maximum take value for both list queries.
defaultValue: 10 does not cap supplied values. A caller can request an arbitrarily large page, and both service methods pass that value directly to Prisma. Apply the existing project page-size validation policy, or clamp the value in the service.

Return myRole only for approved collaborators.
getProblem grants collaborator access only when status is Approved. However, this helper returns Editor or Reviewer for pending and rejected collaborator records on published problems. This can make clients present authoring capabilities to an ineligible user.
- return myCollaborator?.role ?? null

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Apply the publication filter to the total query.
The list query excludes Draft and Ready records, but the count query does not. total can exceed the number of records available in data, which produces empty advertised pages. Add status: ProblemStatus.Published to the count predicate and add a pagination test for mixed statuses.

const total = await this.prisma.problem.count({

Validate judge limits before persistent side effects.
This exception occurs after SubmissionService.createSubmission creates the submission and its result records. The request then fails without an AMQP message, leaving those records in Judging. Test submission paths can also leave cached Judging state.
Validate the limits before creating submission state, or clean up all created state atomically when this exception occurs.

만들당 통합으로 Problem 필드가 nullable이 되면서 client 응답 DTO (ProblemResponseDto, ProblemsResponseDto)까지 nullable로 넓혀졌으나, 이는 기존 프론트엔드 계약을 깨뜨린다. status=Published 문제는 필수 필드가 항상 채워져 있으므로 DTO는 non-null로 되돌리고, 조회 경계에서 ensurePublishedProblemContent로 불변식을 검증한다 (Draft/Ready 만들당 문제는 만들당 전용 조회 API로 다룬다). 또한 각 호출부에 흩어진 status: Published 필터를 PUBLISHED_PROBLEM_WHERE 공통 상수로 모아 새 조회 경로에서 누락되지 않도록 한다.
