Whole-channel inclusion: ScienceEtonnante is an honest teaching channel (title sample + 3 transcripts read: All three samples lack transcripts, but titles/descriptions align with the channel's established pattern of deep science explainers, consistent with the prior 'whole' verdict.); this title passed a strict title check (sonnet) after a labelling pass.
