Omni

Talos node discovery for swamp, via Sidero Omni. Omni is the control plane for fleets of Talos Linux machines. The @mccormick/omni/inventory model asks Omni for that fleet state and turns it into a typed swamp inventory: one node resource per managed machine (hardware, network, Talos version, cluster role, connection and readiness state), one cluster resource per cluster with rolled-up machine counts, and a single summary roll-up. The discover method fans out across Omni's COSI resources — machine statuses, cluster-machine statuses, machine identities, and clusters — and merges them by machine UUID in one execution. Read-only: the model only issues omnictl get calls and never mutates Omni state. Transport is the omnictl CLI authenticated with an Omni service account passed through the environment; the service-account key is supplied through a vault, marked sensitive, and redacted from logs and error text.
