What changed?
New data, not new noise.
A running record of source updates across selected charts: what moved, when the observation belongs, and when the dashboard detected it.
A routine pipeline refresh creates no entry. Estimates, projections, maps, rankings, and sparse annual series are excluded unless they receive a chart-specific rule. Detection is mechanical; interpretation remains editorial.

Current monitored baseline
Latest available value for every configured series. These are reference points, not newly detected changes.
Every event links to its chart, methodology, and exact source. Historical source revisions may change previously published values.
