== UUID Types ==
 +
=== Regular UUIDs ===
 +
These are just standard [https://www.rfc-editor.org/rfc/rfc9562.html#name-uuid-version-1 RFC9562 Version 1 UUIDs] with the above node data.
 +
 +
=== Title-specific UUIDs ===
 +
These UUIDs are specific to the title that requested them to be generated, specifically, using the unique ID portion of the title ID of that title.
 +
 +
The following technique is used internally to generate these UUIDs:
 +
 +
- Generate or use an existing regular UUID the with the above mentioned node data (<code>regular_uuid</code>)
 +
 +
- <code>hash = SHA256 ( byte-swapped unique ID (thus, big endian) + 095E273A + 48-bit node data from regular_uuid )</code>
 +
 +
- <code>output_uuid = regular_uuid[0:9] + hash[10] | 0x1 + hash[11:16]</code>
