| description | Create or modify an EF Core migration for PlaylistMiner database schema changes, with review and verification steps. |
Create a new migration after modifying entities or DbContext.
Verify changes:
git diff src/PlaylistMiner.Core/Models/
git diff src/PlaylistMiner.Infrastructure/Data/
Create migration (use descriptive name like AddVideoStatusColumn, CreateSearchIndexes):

dotnet test tests/PlaylistMiner.IntegrationTests
dotnet ef migrations remove # Remove last unapplied
dotnet ef database update <PreviousMigration> # Rollback applied
