/public- Unencrypted data, visible by anyone
- History encoded directly in the hash-linked structure
/p- A cached reduction of the
/publictree - Exists to make short, friendly relative links
- Relative is relative to some root
- Permalinked if the root is a CID
- Latest link if the root is a mutable pointer such as DNSLink
/private- Encrypted data, with contents fully encrypted
- Includes:
- Private files
- Key sharing
The public and private subtrees have an identical API:

Files (leaves) do not have a canonical path. This is a DAG, not a tree. They DO have a canonical hash (content addressing).
