I really want to know how to XXXXXXX will be generated and how can file JSON file map with the manifest file. Thanks for your help

Answer 1

The suffix is the CRC64 calculated by the entities content in this JSON file, and the manifest file stores the total CRC64 aggregated by all the JSON files. This is to ensure that file list is complete and each JSON file isn't corrupted respectively.
