Refresh tiers
New candidates are validated promptly. High-traffic profiles are targeted every 3–7 days, regular profiles around every 30 days, and cold profiles every 90–180 days. Failed or deleted profiles use exponential backoff.
Change control
Response fingerprints reduce unnecessary writes and image downloads. New direct observations may replace current display values. A current observation record is not a complete change history; a longitudinal study requires separately preserved, comparable snapshots.
Limitations
Public data can change between refreshes, and platform access can fail. A displayed freshness date describes our observation, not the time a creator changed an offer. Refresh intervals are targets, not guarantees; visitors should confirm prices and offers on the official creator page.
