Unifi

Custom/static DNS records on a local UniFi Network controller. The @mccormick/unifi/dns model reads, upserts, and deletes the custom DNS records a UniFi OS console serves on its LAN. list_records writes one dns_record resource per entry; upsert_record creates or updates a single record in place (find by key+type, PUT when it exists, else POST); delete_record removes one (idempotent). The mutating methods are gated by a live pre-flight check that confirms the controller is reachable before any write. This turns a cutover DNS flip — repointing a hostname at a new host — into a composable, reusable model method. Targets the local controller's internal v2 API (/proxy/network/v2/api/site/<site>/static-dns) with an X-API-KEY header. The cloud Site Manager API (api.ui.com) cannot edit DNS — use a key issued on the local UniFi OS console (Settings → Control Plane → Integrations). The api key is supplied through a vault, marked sensitive, and redacted from logs and error text.
