CliqHub stops resending the command and shows the outcome. Acking an unknown or already-acked command changes nothing. Daemon only: requires the daemon's realm token (`Authorization: Bearer cliq_dt_…`). User tokens are refused. Daemon in the token realm; command addressed to it. ## OpenAPI ````yaml /openapi/hub-by-tag/hub-daemons.yaml post /v1/daemons/ack_command openapi: 3.0.3 info: title: 'CliqHub API: Daemons' version: 1.0.0 description: >- Daemons (`cliqd`) connected to CliqHub. A daemon joins a realm with a realm token (`cliq_dt_…`, from Generate a token with `type: realm`, or `cliq login` on the daemon). With that token it registers, sends a heartbeat, reports its installed teams, refreshes the realm's access list and acknowledges each command CliqHub sends it. People list, inspect and remove daemons. A daemon is `online` while it sends heartbeats, then `stale`, then `offline`; `removed` once deregistered or removed. servers: - url: https://{host} variables: host: default: cliqhub.io description: CliqHub host security: [] tags: - name: Daemons description: >- Daemons (`cliqd`) connected to CliqHub.
