About these numbers

Known agent: a checked signature or a vendor's user agent · Declared: named itself, unchecked · Automation: an HTTP library or headless browser · Human: a browser.
Sample data from a fixed seed rotation. Patterns here are not behavioral; a real pilot's traffic will look different.
Intent categories are guessed from event names (meter or usage is Metering, checkout, payment or card is Checkout, and so on). An intent matching none is Other.
"Guessed": the event carried no status code, so the failure was read from the event name (api_call_401, for instance).
