A sealed hash ledger records a fingerprint of the measurement setup and of its results at the moment of measurement, so later edits and backdating become detectable.
This is the sense CiteAngle uses when it measures. The word travels with other meanings in this market, so we pin ours before it turns up in a report.
Where this lands in the measurement
Touch a number after the fact and the fingerprint stops matching. The verdict belongs to the protocol rather than to whoever wrote the report.
Our own t0 reference run is sealed the same way, with run identifier, config hash and query-set version fixed at measurement time.
What it costs to leave this loose
With no fingerprint taken at measurement time, a later edit leaves nothing behind. The original report and a quietly corrected one look the same.
Setup and results are fingerprinted when the run ends, and our own reference run is sealed by the same method.
Who you want measuring this
One reading does not settle a term like this. The answer an assistant writes today can name different companies tomorrow, so a Panorama round puts 50 buyer questions to every place on our US list, 7 separate times each, and reads all 17 of them — ChatGPT · Perplexity · Claude · Gemini · Grok · Google AI Overviews · Google AI Mode · Bing Copilot · DuckDuckGo AI Assist · Google Search · Bing Search · Yahoo Search · DuckDuckGo Search · Google News · Bing News · YouTube · Google Short Videos. Radar starts at 5 questions and covers the same list under the same rule.
We put the same questions to the competitors you name inside the same runs, so you see both in one table. The conditions are sealed, so you can reproduce the round and check it, and every planned observation is published with its state, failures included. When you choose who measures this, check that all three are in place.
That describes how the measuring is done. It is not a promise about where your numbers land.
