Package apple is the lifecycle behind the C ABI in bridge/apple: an Apple NetworkExtension provider prepares a configuration, applies the returned settings to the system, then starts the engine on the utun descriptor the system gave it.

Package cli is the headwire command line shared by every program: the headwire binary adds run, and Headwire.app adds its profile and GUI verbs.

Package config parses and validates headwire's INI configuration: an Interface section, optional repeated [DERPRegion] sections forming a static DERP map, and repeated Peer sections.

Package discokey derives a node's discovery key from its node private key.

Package engine drives tailscale.com's wgengine and magicsock from a static headwire configuration: no control plane, no LocalBackend.

Package status is the status socket's field vocabulary, shared by the client that builds a request and the engine that answers it.
