-  Day closes from CoinGecko landed one day early: its price at midnight UTC is the close of the

-  days old now takes its place. No database change.
+  A backup made on demand or before removing prices no longer replaces the snapshot of that day:

+  expected number of calls counts one day call per distinct request, so the ECB source no longer
+  looks behind. The AI tools now report which version of the server runs. No database change.
