- DomainError struct with Code() string method replaces plain errors.New sentinels; errors.Is() still works via pointer equality - UUIDCreatedAt(uuid.UUID) time.Time helper extracts timestamp from UUID v7 - Add TagOffsetPage, CategoryOffsetPage, PoolOffsetPage - FileListParams fields grouped with comments matching openapi.yaml params - Fix mismatched comment on UserPage Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
