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
[[claim-aster-1994-rendered-math-as-pitched-spatial-audio|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 [[claim-nemeth-code-stayed-private-until-witcher-request|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.
