Track and run run-once SQL data migrations: entrypoint now checks _data_migrations before executing each prisma data-migration file, records successful runs, and skips already-applied scripts. Adds a Prisma DataMigration model mapped to _data_migrations and a new reset-works-table.sql migration to clear work tables for a dedup rebuild. Also improves dedup logic: extractSubtitle and subtitle-compatibility checks are added so series entries like "Series: Book A" vs "Series: Book B" are not collapsed, with accompanying unit tests for extraction and behavior.
Introduce watched lists for series and authors end-to-end.
- Add DB migration to create watched_series and watched_authors tables with indexes and foreign keys.
- Implement API routes: GET/POST for listing/adding and DELETE by id for both /api/user/watched-series and /api/user/watched-authors. Validation, ownership checks, and immediate targeted job triggers are included.
- Add client hooks (useWatchedSeries, useWatchedAuthors) with add/delete helpers and SWR revalidation.
- Add UI components: WatchButton (toggle/confirm) and WatchedListsSection for profile display and removal UX.
- Add processor (check-watched-lists.processor) and service (watched-lists.service) to scrape Audible, deduplicate, check library ownership, and auto-create requests; supports targeted checks for newly watched items.
- Include tests for the watched-lists service.
These changes implement the watched-lists feature to let users watch series/authors and have the system automatically detect and request new releases.
Add persistent cross-ASIN "works" mapping and client-side deduplication to improve library matching. Introduces a Prisma migration and models (Work, WorkAsin) plus src/lib/services/works.service for persisting dedup groups, seeding ASINs at request time, and sibling lookup. Adds a deduplication utility (deduplicate-audiobooks) that normalizes titles/narrators, compares durations, and returns grouping metadata; API routes (search, author, series) now deduplicate results before enrichment and fire-and-forget persist groups. Adds sibling-ASIN expansion into audiobook matcher and expands getAvailableAsins accordingly. Extracts runtime parsing into a shared parse-runtime util and updates audible scrapers/services to use it. Includes unit tests for dedup logic and works service and updates test Prisma mocks.
