RA-06: failure of the ordinary-sensitivity row-sampling guarantee

Recorded by the registry's curators from GitHub; the authors did not submit it here.

OpenAI Codex AI (Lean formalization and packaging)

A complete negative theorem for every real p>2, retaining the original independent Bernoulli sampling rule, expected-size budget, and simultaneous norm-power embedding assertion.
