- Changed blob table to use ID (UUID) as primary key instead of hash - Blob records are now created at packing start, enabling immediate chunk associations - Implemented streaming chunking to process large files without memory exhaustion - Fixed blob manifest generation to include all referenced blobs - Updated all foreign key references from blob_hash to blob_id - Added progress reporting and improved error handling - Enforced encryption requirement for all blob packing - Updated tests to use test encryption keys - Added Cyrillic transliteration to README
