Extend §4 from "the ceiling is high" (virtuoso turntablism) to "the floor is open" (the amateur's right to fumble) — the paper's clearest tie to AC's own amateur-first ethos: - heta-uma ("unskilled-good," Yumura Teruhiko / Garo) via Gravett; Tori Kudo's Maher Shalal Hash Baz (amateur ensemble, inspired mistakes) as a Japanese primary source; Novak's Japanoise (a scene built on the refusal of mastery, circulating on traded cassettes — which also loops back to the tape theme). - Chun (Programmed Visions) anchors the "downsampling is a choice, not a limit" claim: software naturalizes its decisions so a fixed 1.0x feels like a given. The itemized menu forecloses the amateur's fumble most of all — nothing to be bad at, so nothing to get good at. Women-authored citations now 12/36 (33%; 31% strict); non-Western improved (Kudo, Eshun, Chun) but still short of 20%. 10pp; passes the column gate.
