internal/

syncs interfaces, addresses, VRF-aware address dedup, LLDP-discovered cable connections, and on-device ELINEs (as NetBox L2VPNs of type EVPL) from live network devices into NetBox.

Package jobevent lets a sync tool (internal/dns, internal/icinga, internal/librenms, internal/netbox, internal/lime) report structured info/warning/error progress instead of ad hoc fmt.Println/slog calls.

Package jobscheduler runs user-defined JobSchedule rows: each due schedule triggers the same StartJob path as the Job overview page (one sync target, or a sequenced "sync all").

Package ldapauth implements the search-and-bind flow used to authenticate a user against an LDAP/Active Directory server and to read the attributes (email, display name, group membership) needed for local auto-provisioning and role sync.

Package mail sends outbound email over the shared SMTP relay settings (Settings.Smtp*/EmailSender, edited on the admin UI's "Email" destination tab, projected into util.CommonConfig by util.NewCommonConfig).

Package worker runs predefined shell commands dispatched by the primary over the hub transport (see hub.go/hub_agent.go).
