  "note": "Snapshots are written only when a reading changes: a gap in ts means \"no change observed between readings\", never \"not measured\" and never \"interpolated\". Readings from different sources are separate lineages that do not confirm one another — subtracting across them can attribute a change to a period nothing was actually read in.
