How recently a table was updated, measured against how recently it should have been.

Data freshness measures the gap between now and the last time a table received data — and whether that gap is normal. A table that updates hourly but hasn't changed in a day is stale, even if every row in it is correct. Freshness is about timeliness, not accuracy.
Stale data is one of the most common and most dangerous failures, because nothing looks broken: the dashboard still loads, the numbers are still there, they're just old. Decisions get made on yesterday's reality without anyone realizing the data stopped moving.
Tabkeel learns each table's normal update rhythm and alerts you when an expected refresh doesn't arrive — before the stale number reaches a dashboard.
