Checks 1–7

Marc Andreessen is a highly influential technology investor and thought leader based in Menlo Park, with a massive social media following of over 2 million. He presents as a techno-optimist with strong pro-American values, frequently championing building and innovation while maintaining an energetic, enthusiastic communication style. His self-identification as 'spectrum boy' and extensive engagement patterns (269k+ favorites, following 28k+) suggest deep platform immersion and neurodivergent self-awareness.

Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
