Method

Names were extracted mechanically by capitalisation from the public corpus (github.com/mrcrtr1979-droid/namebeam-visibility-index), matched on canonical form. Generic names filtered. Three engines only (ChatGPT gpt-5-mini, Claude bedrock haiku 4.5, Gemini flash lite). Local-business questions only. This is a count of agreement, not a measurement of causes or outcomes.
