+# Release Changes: EF Core Migrations for Artist Search Engine
+
+**Related Plan**: EF Core Migration Implementation for ArtistSearchEngineServiceDbContext
+**Implementation Date**: 2026-06-22
+
+## Summary
+
+Migrated the Artist Search Engine DecentDB database from using `EnsureCreatedAsync()` (which only creates schema on first run) to proper EF Core migrations via `MigrateAsync()`. This enables schema versioning, proper migration tracking, and eliminates hand-rolled idempotent DDL blocks that were maintained manually in `ArtistSearchEngineService.cs`.
+
+## Changes
+
+### Added
+
+- `src/Melodee.Common/Data/ArtistSearchEngineServiceDbContextFactory.cs` - Design-time DbContext factory for `dotnet ef` tooling to generate migrations
+- `src/Melodee.Common/Migrations.ArtistSearchEngine/ArtistSearchEngine/20260622141948_InitialArtistSearchEngineSchema.cs` - Baseline migration with raw SQL matching the existing production schema exactly
+- `src/Melodee.Common/Migrations/ArtistSearchEngine/20260622141948_InitialArtistSearchEngineSchema.Designer.cs` - EF Core migration metadata/snapshot
+- `tests/Melodee.Tests.Common/Data/ArtistSearchEngineServiceDbContextMigrationTests.cs` - 3 comprehensive tests validating migration behavior on fresh files, existing schema, and production schema copy
+
+### Modified
+
+- `src/Melodee.Blazor/Program.cs` - Added `MigrationsAssembly("Melodee.Common")` to DecentDB options for ArtistSearchEngineServiceDbContext so EF Core finds the dedicated migration folder
+- `src/Melodee.Common/Services/SearchEngines/ArtistSearchEngineService.cs` - Replaced `EnsureCreatedAsync()` + 3 hand-rolled DDL blocks (`EnsureHousekeepingIndexesAsync`, `EnsureLocalArtistAliasLookupAsync`, `BackfillLocalArtistAliasLookupAsync`) with single `MigrateAsync()` call; kept `BackfillLocalArtistAliasLookupAsync` as a data-seed step
+- `src/Melodee.Blazor/Services/DoctorService.cs` - Simplified `ProbeArtistSearchDatabaseAsync` to just verify connectivity without running DDL
+- `src/Melodee.Cli/Command/DoctorCommand.cs` - Changed new database creation from `EnsureCreatedAsync()` to `MigrateAsync()`
+
+### Removed
+
+- Hand-rolled `EnsureHousekeepingIndexesAsync` method (index creation now in migration)
+- Hand-rolled `EnsureLocalArtistAliasLookupAsync` method (table + index creation now in migration)
+- Raw `CREATE INDEX IF NOT EXISTS` and `CREATE TABLE IF NOT EXISTS` blocks from startup path
+
+## Release Summary
+
+**Total Files Affected**: 8
+
+### Files Created (4)
+
+- `src/Melodee.Common/Data/ArtistSearchEngineServiceDbContextFactory.cs` - Design-time factory for migration generation
+- `src/Melodee.Common/Migrations/ArtistSearchEngine/20260622141948_InitialArtistSearchEngineSchema.cs` - Baseline migration with idempotent raw SQL matching production DecentDB schema
+- `src/Melodee.Common/Migrations/ArtistSearchEngine/20260622141948_InitialArtistSearchEngineSchema.Designer.cs` - Migration metadata
+- `tests/Melodee.Tests.Common/Data/ArtistSearchEngineServiceDbContextMigrationTests.cs` - Migration tests
+
+### Files Modified (4)
+
+- `src/Melodee.Blazor/Program.cs` - MigrationsAssembly configuration
+- `src/Melodee.Common/Services/SearchEngines/ArtistSearchEngineService.cs` - Switched to MigrateAsync, removed hand-rolled DDL
+- `src/Melodee.Blazor/Services/DoctorService.cs` - Simplified health probe
+- `src/Melodee.Cli/Command/DoctorCommand.cs` - Switched to MigrateAsync for new database creation
+
+### Dependencies & Infrastructure
+
+- **New Dependencies**: None (uses existing `DecentDB.EntityFrameworkCore` and `DecentDB.EntityFrameworkCore.NodaTime`)
+- **Updated Dependencies**: None
+- **Infrastructure Changes**: Created dedicated migration folder `src/Melodee.Common/Migrations.ArtistSearchEngine/` for isolated migration tracking
+- **Configuration Updates**: `MigrationsAssembly("Melodee.Common")` on DbContext options to locate migration history table
+
+### Deployment Notes
+
+1. **Production file compatibility**: The baseline migration uses raw SQL that exactly matches the existing production `.ddb` schema (verified via DecentDB CLI dump). Running `MigrateAsync()` against the existing file is a no-op — it inserts the `__EFMigrationsHistory` row and leaves all tables/indexes/data intact.
+
+2. **New environments**: Fresh `.ddb` files will have the full schema created by the migration's `CREATE TABLE IF NOT EXISTS` / `CREATE INDEX IF NOT EXISTS` statements.
+
+3. **Future schema changes**: New schema modifications should be done by modifying the entity models, then running `dotnet ef migrations add <Name> --project src/Melodee.Common --startup-project src/Melodee.Blazor --context ArtistSearchEngineServiceDbContext --output-dir Migrations.ArtistSearchEngine` to generate proper incremental migrations.
+
+4. **Test fixture**: The production schema test requires setting `MELODEE_TEST_ARTIST_SEARCH_ENGINE_DDB` environment variable to a DecentDB file matching the production schema (not committed due to size).
+
+## Local Development Baselining Fix
+
+**Problem**: Local `.ddb` files created with the old `EnsureCreatedAsync()` path lacked the `__EFMigrationsHistory` table. When `MigrateAsync()` ran, it tried to read the history table (failed), then compared the model snapshot to the database and reported "pending changes" — even though the schema matched.
+
+**Root cause**: The model snapshot (in `Designer.cs`) had `BOOLEAN` for `IsLocked` while the database had `INT64` (from the old `EnsureCreatedAsync()`). EF Core's model validator flagged this as a schema mismatch.
+
+**Fix applied**:
+1. Added explicit value converter for `Artist.IsLocked` in `ArtistSearchEngineServiceDbContext.OnModelCreating()` mapping `bool?` → `int?` (0/1) stored as `INTEGER`
+2. Updated the baseline migration's `Designer.cs` model snapshot to match the database: `IsLocked` now uses `INTEGER` with the value converter (instead of `BOOLEAN`)
+3. **No additional migration was created** — the baseline migration's model snapshot was manually corrected to match the physical database schema, so EF Core's model validator sees zero differences
+
+**Result**: Existing local `.ddb` files with historical data work unchanged. `MigrateAsync()` sees the baseline history row, finds zero pending migrations, and proceeds without errors.

 ## [Unreleased]
 
+## [2.2.0] - 2026-07-11
+
+### Added
+
+- Admin health checks now recognize DecentDB error 8 and automatically open a
+  migration dialog with the matching prebuilt release, configured source and
+  destination paths, copyable `decentdb-migrate` commands, verification steps,
+  safe replacement scripts, and links to the official DecentDB guidance.
+- Media Artist export/import: export all search-engine artist data (artists, albums,
+  aliases) as JSON via the `/admin/mediaartists` page; import JSON exports with optional
+  overwrite and full preview of artist/album/alias counts.
+- ArtistSearch database auto-creation in Blazor Doctor: when the `.ddb` file is missing
+  but the parent directory exists, the health check now creates it via EF Core migrations
+  instead of reporting an error.
+
+### Changed
+
+- Replaced the hand-rolled raw-SQL ArtistSearch initial migration with a proper
+  model-driven EF Core migration that uses `CREATE TABLE IF NOT EXISTS` for idempotent
+  application on both fresh and existing databases.
+- Added a second `SyncMusicBrainzUuidColumns` migration as a no-op to satisfy EF Core's
+  migration chain. DecentDB reports `Guid`/`byte[]` columns as `UUID` in the EF model but
+  stores them as `BLOB`, and `ALTER COLUMN TYPE` to `UUID` is unsupported by DecentDB
+  (only `INT64`, `FLOAT64`, `TEXT`, `BOOL`). The no-op migration records itself as applied
+  without attempting the unsupported `ALTER`, keeping `MigrateAsync` stable.
+- Updated the DecentDB providers to `2.16.1`, SkiaSharp managed and Linux native
+  assets to `4.150.0`, Radzen to `11.1.3`, and related runtime, UI, test, and
+  tooling dependencies.
+- Chart editing, user, user-group, and podcast detail routes now bind public
+  GUID API keys directly instead of internal numeric IDs or custom string
+  parsing.
+- Enabled solution-wide XML documentation output so build-time unused-using
+  analysis runs consistently, and corrected malformed API documentation and
+  formatter configuration.
+
+### Fixed
+
+- Resolved EF Core "pending model changes" error for `ArtistSearchEngineServiceDbContext`
+  by regenerating the model snapshot to match the `IsLocked` `INTEGER` column type
+  configured in the DbContext.
+- Resolved DecentDB `ALTER COLUMN TYPE supports only INT64, FLOAT64, TEXT, and BOOL` crash
+  during ArtistSearch migration by making the `SyncMusicBrainzUuidColumns` migration a no-op.
+- ArtistSearch database is now auto-created on first use when the `.ddb` file is absent,
+  eliminating the "database is empty or not initialized" error that previously required
+  manual intervention.
+- Paged ArtistSearch queries now retrieve the requested page before counting
+  results, preventing DecentDB positional parameters from carrying across
+  commands and causing missing-parameter failures.
+- Chart edit navigation now uses the chart API key, and missing chart album
+  matching is accent-insensitive.
+- Aligned the SkiaSharp managed and Linux native packages and moved image
+  drawing to the supported sampling API, preventing native `119.0` and managed
+  `150.0` incompatibility failures during image processing.
+- Solution Debug and CI analyzer builds now complete without dependency,
+  obsolete API, or XML documentation warnings.
+- Version bump automation now promotes release notes without moving the fresh
+  Unreleased heading above the changelog's Jekyll front matter.
+- ArtistSearch initialization now uses migrations for relational databases and
+  schema creation for non-relational providers, preventing OpenSubsonic
+  `getTopSongs` failures in in-memory hosts.
+
+### Security
+
+- Pinned `Microsoft.OpenApi` to patched version `2.7.5`, preventing crafted
+  circular schema references from terminating the process during OpenAPI
+  document parsing.
+
