Cairn blogShipping notes from Cairn: what shipped, how to use it, and why it works the way it does.https://cairndev.sh/enWhere a human approval belongs in an ML pipeline, and where it doesn'thttps://cairndev.sh/blog/where-a-human-approval-belongs.htmlhttps://cairndev.sh/blog/where-a-human-approval-belongs.htmlPut a person in front of the leg that spends money or changes production, and show them the evidence. Let data decide everything a number can decide. How Cairn's gates are built around that rule, and what we deliberately keep away from approvers.Fri, 09 Oct 2026 00:00:00 GMTVibhu SharmaEngineeringgovernanceapprovalspipelinesFine-tune with a cost gatehttps://cairndev.sh/blog/fine-tune-with-a-cost-gate.htmlhttps://cairndev.sh/blog/fine-tune-with-a-cost-gate.htmlHow Cairn's fine-tune pipeline prices a run before a GPU starts, checks the trained model against held-out data, and waits for a person before anything is promoted. The commands to run it are at the end.Thu, 08 Oct 2026 00:00:00 GMTVibhu SharmaGuidetraininggovernancecliFrom a DAG of scripts to a governed pipelinehttps://cairndev.sh/blog/from-a-dag-to-a-governed-pipeline.htmlhttps://cairndev.sh/blog/from-a-dag-to-a-governed-pipeline.htmlIf your ML work already runs as a DAG of scripts, Cairn doesn't replace the tools that run it. It adds what a DAG doesn't record or enforce: cost caps, data and human gates, one record per leg, and a trace you can replay.Wed, 07 Oct 2026 00:00:00 GMTVibhu SharmaGuidepipelinesgovernancemigration
