Package auth implements challenge-response authentication over a libp2p stream.

Package dataroot provides platform-specific data directory resolution for LinkSelf's storage hierarchy:

Package devicesync provides transparent data replication between devices sharing the same DID (identity).

Package dht wraps libp2p Kademlia DHT to provide DID-based Provide/Find for LinkSelf.

Package did implements did:key generation, parsing, and verification for LinkSelf.

Package envelope provides a thin message type wrapper for multiplexing DeviceSync, GroupShare, and plain messages over the same transport.

Package group implements the group concept: member set (2+), owner, leave, dissolve.

Package groupshare provides API-like data sharing between different DIDs in a group.

Package node assembles a LinkSelf node: libp2p Host + DHT (DID Provide/Find) + auth.

Package pairing implements a simple device pairing protocol for LinkSelf.

Package permission provides table-level access control using the role DAG.

Package presence implements the device-presence directory that an always-on node (relay / bootstrap) exposes so that a user's devices can find each other's current reachable address — the discovery piece of two-layer multi-device sync (browser leaves cannot accept inbound connections, so they publish their Circuit-Relay address here and look up their siblings).

Package role provides a role hierarchy as a directed acyclic graph (DAG).

Package roster implements the device roster: the abstraction that unifies a user's devices under the two-layer identity model (data-sync-decisions §4.2 P3).

Package sqlproxy provides a SQL query interface that wraps SQLite and captures write operations for sync.

Package storeforward implements Store-and-Forward: queue messages by destination DID, flush when the peer is reported online (e.g.

Package syncdb implements the sync layer: meta attachment, immediate group delivery, last-write-wins apply.
