+# No API key is needed. Sources must belong to a configured region's IATAs.
+# Group endpoints are not supported: their names cannot be attributed to each IATA.
+# At most 16 sources, 64 names per source, 64 KiB per response; no page scraping.
+# Catalogues and ETags persist in PostgreSQL. Failed refreshes retain known names.
+# Refresh success/failure/freshness is logged under component=meshmapper.scopes.
+# Removing/turning off a source deactivates its imported matching keys on restart;
+# historical scope identities and recorded evidence are retained.
