Amazon, Audible, and GoodReads parsers now fetch full detailed metadata
(4 results each) instead of returning lightweight previews. Adds randomized
500-1500ms delays between requests. GoodReads retries with title-only search
(2 results) when title+author yields no matches.

* fix(kobo-sync): Kobo reading state sync by returning the device expected shape and improve management with new DTOs and timestamp normalization
- Introduced `KoboReadingStateList` and `KoboReadingStateRequest` DTOs for improved handling of reading states.
- Updated `KoboController` to utilize the new DTOs and log request bodies.
- Enhanced `KoboReadingStateService` to normalize timestamps during reading state updates and merges.
- Adjusted repository queries to include user ID for better data integrity.
- Updated tests to reflect changes in DTOs and repository interactions.
* feat(kobo-sync): Enhance Kobo reading state management with user ID integration
* feat(kobo-sync): Add JSON annotations to KoboReadingStateList for improved serialization
* refactor(kobo-sync): Update repository and service methods to enhance reading state retrieval logic
- Replaced the existing method for fetching reading states with a new query that orders results by priority and timestamps.
- Updated service classes to utilize the new repository method for improved data handling.
- Adjusted unit tests to reflect changes in repository interactions.
* Enhance KoboReadingStateService and add database migration for user_id
- Added a new column `user_id` to the `kobo_reading_state` table with a foreign key constraint referencing the `users` table.
- Updated the `KoboReadingStateService` class by adding a new method to check for blank values, improving code readability and maintainability.
Refactor bulkUpdateMetadata to process each book update in its own transaction using PROPAGATION_REQUIRES_NEW, improving concurrency safety. Add BookMetadataServiceConcurrencyTest to verify correct fetching strategy and transactional behavior.

* feat: Add comprehensive Calibre metadata extraction system - Implemented configurable field mapping system for Calibre user_metadata - Added support for series_total custom column extraction - Pre-built mappings for ALL BookMetadata fields (20+ fields) - Added support for Set fields (tags, moods, categories, authors) - Lowercase field names with underscores (Calibre requirement) - Multiple ISBN support (ISBN-10 and ISBN-13 simultaneously) - ISBN hyphen handling (strips hyphens before validation) - Type-safe parsing (String, Integer, Float, Double, Set) - Professional logging with IDENTIFIER prefix - Added CALIBRE_FIELD_MAPPING_REFERENCE.txt documentation - Updated .gitignore and created .dockerignore for test files
* Updated gitignore
* Delete CALIBRE_FIELD_MAPPING_REFERENCE.txt
* Remove unnecessary files: example.epub and og_metadata.java
* Refactor EpubMetadataExtractor to address PR review feedback
- Eliminate DRY violations in identifier extraction with helper methods
- Fix Build-to-Check anti-pattern using processedFields tracking
- Move regex patterns to static constants to avoid recompilation
- Replace magic numbers with calculated prefix lengths
- Consolidate repetitive Set field and pagecount parsing patterns
- Remove excessive documentation and comments
- Remove unrelated .dockerignore and .gitignore entries
* chore: trigger CI/CD pipeline
* Add @Singular annotation to collection fields to support builder accumulation
* Update identifiers to URN format for Calibre compatibility
* fix: resolve MetadataChangeDetectorTest failures and enhance Calibre EPUB integration
- Fixed NullPointerException in testEdgeCase_emptyCollectionToNull_returnsTrue()
- Fixed NullPointerException in testHasValueChanges_whenEmptySetToNull_returnsTrue()
Implementing @Singular for moods and tags prevents metadata fields from being null,
which then fails edge test cases. Since we are no longer double looping during
metadata extraction, @Singular is not needed. Removing it allows the edge case
tests (by Balázs Szücs) to pass.
- Removed douban fields from persistence layer (kept in DTO for DoubanBookParser)
I was under the impression we were saving this value to the DB, but as far as I
can find, we only use Douban data for searching. Adding to the identifiers section
would raise issues with the database not having where to store that value.
Database modifications are left to the professionals.
- Added support for all identifier formats (URN and simple prefix)
Calibre only detects identifiers during IMPORT if they are in URN format.
However, it saves them back as simple prefix. Booklore now handles both.
- Added removeAllCalibreMetadata() to strip all Calibre traces
Cleans up saved EPUBs in Booklore's library, removing all Calibre metadata traces.
- Ensures clean EPUB 3 compliant output with only booklore:* tags
ALL metadata is now saved by Booklore into EPUBs using booklore:* tags.
This preserves Booklore's metadata and we can read it back during import.
Calibre support is ONLY during IMPORT, as it should be since this is the
Booklore project.
(If Calibre users want to extract Booklore metadata, they can build a Calibre
plugin to extract booklore:* tags.)
No longer use #genres or #categories. We stick to dc:subject as suggested,
and Booklore tags can be read from Calibre custom column #extra_tags.
We store tags as booklore:tags.
Removed all tests that used #genres/#categories.
Added tests to check booklore:* tags extraction.
* fix: Remove DoubanId copy helper call - upstream MetadataClearFlags missing isDoubanId()
* Fix Calibre moods and tags extraction from EPUB metadata
- Add fallback logic to check alternative key names (value, #val#) if #value# is missing
- Maintain compatibility with upstream metadata structure changes
* fix: resolve rebase conflicts and compilation errors - Fixed missing closing brace in MetadataRefreshService.java - Added MoodRepository and TagRepository to BookCreatorService - Added addMoodsToBook() and addTagsToBook() methods - Fixed EpubProcessor to use new methods
* Restore Booklore's metadata persistance, Logic Lost during Rebase + Added support for Lubimyczytac and ranobedb
Fixed lubimyczytac metadata not saving during EPUB bookdrop imports.
Root cause: The Angular bookdrop form was missing lubimyczytacId and lubimyczytacRating fields, preventing these values from being sent to the backend during finalization.
Backend fixes:
- EpubMetadataExtractor: Fixed method references with explicit lambdas for lubimyczytac field setters (ranobedb also updated preventively)
- BookMetadataUpdater: Fixed method references with explicit lambdas for lubimyczytac field updates (ranobedb also updated preventively)
Frontend fix:
- bookdrop-file-review.component.ts: Added lubimyczytacId and lubimyczytacRating form fields to createMetadataForm() and resetMetadata() methods
This ensures lubimyczytac metadata extracted from EPUB booklore:tags flows correctly through: extraction → database → UI form → backend → final book record.
* Restore Original ONLY Calibre custom column name to #pagecount So as not to break other users flow.
* fix: resolve compilation error in EpubProcessor.java - Changed bookEntity.getFileName() to bookEntity.getPrimaryBookFile().getFileName() to fix gradlew build check
* Add EPUB 3 compliant prefix declaration for custom booklore metadata
Declares the booklore: prefix in the package element's prefix attribute according to EPUB 3 specification for custom vocabularies.
* Move hardcoverBookId to standard URN identifier format
Changed hardcoverBookId from custom booklore metadata to standard dc:identifier with urn:hardcoverbook: prefix for consistency with other identifiers.
* UPDATE: migrate hardcover_book_id to VARCHAR and fix related issues
## Changes
### 1. Database Migration
- Changed hardcover_book_id column from INTEGER to VARCHAR(255)
- Supports alphanumeric book IDs from Hardcover API
- Updated HardcoverSyncService to handle String ↔ Integer conversion
### 2. Metadata Editor Fixes
- Fixed metadata change detection for provider-specific fields
- Added missing clearFlags entries: hardcoverBookId, lubimyczytacId, lubimyczytacRating
- Resolves issue where rating/review count fields wouldn't save independently
Affected fields now save properly independently:
- Amazon rating & review count
- Goodreads rating & review count
- Hardcover rating & review count
- Lubimyczytac rating
- Ranobedb rating
### 3. Web Reader Hardcover Sync (Major Fix)
Since I changed the data type for hardcover_book_id I had to update references in the HardCoverSyncService.java This turned out to reveal
the Sync Service was not fully implemented:
- Added Hardcover progress sync to ReadingProgressService
- Previously, HARDCOVER sync only worked for Kobo and KOReader devices
- Web browser reading progress now syncs to Hardcover.app
## Files Modified
- booklore-api/src/main/resources/db/migration/V107__Change_hardcover_book_id_to_varchar.sql
- booklore-api/src/main/java/.../service/hardcover/HardcoverSyncService.java
- booklore-api/src/main/java/.../service/progress/ReadingProgressService.java
- booklore-ui/src/app/features/metadata/.../metadata-editor.component.ts
## Breaking Changes
None - migration handles existing integer IDs gracefully
## Testing
- Hardcover sync tested with web reader
- Metadata editor field updates verified
- Database migration confirmed successful

Add updatedAt timestamp field to EpubProgress, PdfProgress, and CbxProgress
DTOs to support progress conflict detection in the mobile app.
The mobile app uses this timestamp to detect when progress has changed on the
server (e.g., from reading in the web UI) while the app was offline with
local progress, enabling automatic conflict resolution.
- Add GET /api/v1/user-stats/heatmap/monthly endpoint for month-based data
- Keep original /heatmap endpoint unchanged for backward compatibility
- Add findSessionCountsByUserAndYearAndMonth repository method
- Add getSessionHeatmapForMonth service method
