Ok, the solution you implemented in wip-ui seems viable. For now I'm implementing basic web API in cuirass : * api/build/:build * build/:build/log/raw * api/latestbuilds This allows emacs-guix to query cuirass as per hydra. The "queue" api will be implementable when we will support build start/stop/failure detection. Thanks, Mathieu
