FundedSpend checks the official publisher registry weekly, while the publisher releases the underlying file quarterly. Each project keeps its award date, publisher-data coverage date and our retrieval time distinct. A successful check never changes an unchanged award into a newly awarded project. Failed runs are recorded and do not silently overwrite the last completely verified catalogue.
