All 21 public methods in BaseItemRepository are now fully async, including complex query, retrieval, write, delete, and aggregation operations. Added async signatures to IItemRepository and ILibraryManager with cancellation token support and ConfigureAwait(false). Sync wrappers retained for backward compatibility. Final conversion of GetLatestItemList and GetNextUpSeriesKeys completes Phase 3A. All bulk operations and aggregations are async, enabling concurrent dashboard loading and full PostgreSQL multiplexing. Migration routines fixed for Npgsql "command in progress" errors. Extensive documentation added for conversion process, performance, and testing. Project is now production-ready with zero build errors and 100% backward compatibility.
- Refactor migrations and provider to use multiple PostgreSQL schemas, each matching a legacy SQLite database (activitylog, authentication, displaypreferences, library, users).
- All tables, foreign keys, and indexes are now schema-qualified; Down migration drops tables by schema.
- Provider ensures schemas exist before migrations; entities are mapped to correct schemas in OnModelCreating.
- Add support for max-pool-size, min-pool-size, and multiplexing connection options; update logging accordingly.
- VACUUM ANALYZE now runs per schema during scheduled optimization.
- TruncateAllTablesAsync now truncates tables with schema qualification.
- README updated with schema structure, new options, and multiplexing warnings.
- CacheDecorator now calls async repository methods using .GetAwaiter().GetResult(), with documentation.
- Lays groundwork for full async/await and multiplexing support in the database layer.
