Whole-channel inclusion: Cambridge University Astronomy is an honest teaching channel (title sample + 3 transcripts read: All three transcripts show substantive expert lectures/talks explaining astrophysics concepts (information paradox, dark matter-galaxy connections, stellar nucleosynthesis), consistent with the 'whole' verdict.); this title passed a strict title check (sonnet) after a labelling pass.
