Whole-channel inclusion: Matemaks is an honest teaching channel (title sample + 3 transcripts read: All three samples lack transcripts, so the channel verdict relies on the title-sample assessment indicating consistent exam-problem and concept teaching typical of this math channel.); this title passed a strict title check (sonnet) after a labelling pass.
