Repeated-source verification
AI pricing and feature change history
A public timeline of confirmed changes from mapped vendor sources. A changed page must produce the same new signal twice before an event is published.
Monitoring history starts now
No vendor change has yet passed the two-consecutive-observation rule. Initial snapshots never become public “changes.”
The monitor stores only fingerprints privately. Public events contain the tool, date, broad change type and source URL—not scraped vendor copy. Always verify current terms with the vendor.
