Does StereoMath (2024) cite AsTeR/Emacspeak for the pitch-encodes-vertical-position mapping, or present it as novel? (rediscovery vs. acknowledged lineage)

The observation note observation-math-sonification-pitch-for-vertical-recurred-1994-2024 turns on one unresolved fact. StereoMath (Ge and Seo, arXiv 2501.01404, ASSETS '24) maps vertical equation position to pitch — exactly what AsTeR did in 1994. The capture's hop chain is internally in tension: it says StereoMath cites Emacspeak as "sonification prior art," yet also reads the pitch-for-vertical mapping as an innovation the paper treats as its own.

Why it matters. The distinction is the whole interpretive weight of the bridge:

• If StereoMath does not credit AsTeR/Emacspeak for the pitch mapping, this is a thirty-year rediscovery — a tacit accessibility technique reinvented, the sonic echo of private notation that never transmits.
• If it does credit them, it is acknowledged lineage, and the finding is the durability of the idea, not its loss.

What would answer it. Read StereoMath's related-work and references sections directly: does it cite Raman / AsTeR / Emacspeak, and specifically for the pitch-to-vertical mapping (vs. only for general sonification / audio-desktop prior art)? Note whether the paper frames pitch-for-verticality as a contribution. Resolve, then fold the verdict into the observation note and drop its capture-verified hedge.

Progress log

• claim-stereomath-2024-cites-emacspeak-not-aster-as-generic-prior-art, claim-stereomath-2024-frames-pitch-vertical-mapping-as-uncited-novel-contribution — settled by a direct full-text read of StereoMath's paper (arXiv 2501.01404) and all 39 references: the paper cites Raman's Emacspeak once, in a generic sonification clause never connected to pitch or verticality, never names AsTeR, and presents the pitch-for-vertical mechanism itself as an uncited 'novel experience... not commonly found elsewhere.' Verdict: independent rediscovery, not acknowledged lineage — folded into observation-math-sonification-pitch-for-vertical-recurred-1994-2024.
