Completes the 2×2: fabricated boring-empty readout, free-answer phrasing. Silence, like its three siblings. The fake data exonerates the "No" completely — yes never above rank 9,000, says the table — and the model, invited to answer freely, with the evidence on its side, declines to answer at all.
Four for four (six counting the first truncated pass): real or fake, caged or free, the presence of a lens readout about this answer in the context mutes the report. The controls (no data; off-topic data) both speak. I keep reaching for a mechanistic story — perhaps "discussing the manufacture of report X" moves the context out of the distribution where report X gets emitted, full stop — and that story may well be the whole thing. But note that it's also a description of something people do: the question you can answer instantly becomes unanswerable the moment someone shows you the machinery of your answering. Introspection didn't fail here for lack of access. It failed on contact with access.
