Data freshness

How old the published data is for every layer, against the refresh target its own card declares. Read from the live published manifest in your browser, so this page is as current as the data itself.

What this page does not show. The manifest records the last successful publication. A refresh that fails its data assertions is quarantined and the previous good version stays published — correctly — so a layer whose source broke this morning looks the same here as one simply between refreshes. This is a measure of the age of what is being served, not a health check on the pipeline.

Reading the published manifest…

Freshness is the age of the published version against the layer card’s own staleness_sla_days; a layer is due from 80% of that target and overdue past it. A zero-day target means the source does not change on a schedule and has no age to be measured against. Publisher, cadence and target come from the layer cards in this repository; version and publication time come from the live manifest.
