📝 WalkthroughWalkthroughMandeuldang data now integrates with the shared ChangesMandeuldang problem integration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔴 Critical · up to This PR changes shared problem fields to nullable and replaces legacy database structures, but the current version does not typecheck and its migration may fail, discard existing Mandeuldang data, or create invalid relationships. It is not merge-ready until consumers are updated and the migration safely maps and preserves existing data. Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

`@apps/backend/prisma/migrations/20260828120159_integrate_mandeuldang_problem/migration.sql`:
- 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.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Keep the generated Problem type compatible.
These fields now generate nullable Prisma types. The PR objective confirms that this change currently fails the full typecheck. Include the consumer compatibility changes in the same mergeable stack, or defer this nullability transition until consumers handle null.
Also applies to: 281-284
