 UnixFS currently supports two optional metadata fields:
 
 * `mode` -- The `mode` is for persisting the file permissions in [numeric notation](https://en.wikipedia.org/wiki/File_system_permissions#Numeric_notation) \[[spec](https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/sys_stat.h.html)\].
-  If unspecified this defaults to `0755` for directories/HAMT shards and `0644` for all other types where applicable
-  The nine least significant bits represent  `ugo-rwx`
-  The next three least significant bits represent `setuid`, `setgid` and the `sticky bit`
-  The remaining 20 bits are reserved for future use, and are subject to change. Spec implementations **MUST** handle bits they do not expect as follows:
-    For future-proofing the (de)serialization layer must preserve the entre uint32 value during clone/copy operations, modifying only bit values that have a well defined meaning: `clonedValue = ( modifiedBits & 07777 ) | ( originalValue & 0xFFFFF000 )`
-    Any higher level operations interpreting the value must proactively mask-off bits without a defined meaning in the current version of the spec: `interpretedValue = originalValue & 07777`
