The claim-note [[claim-aster-1994-rendered-math-as-pitched-spatial-audio]] rests on
two phrases quoted from T. V. Raman's PhD-thesis page
`cs.cornell.edu/info/people/raman/phd-thesis/html/node72.html`:

- for superscripts, "a change along the audio dimension produces a higher pitched
  voice," and
- for deepening nesting, "the change in voice characteristic produces a sense of
  falling off into the distance."

The 2026-07-11 hop session reached that page and copied the phrases, but this
headless promotion had no web tool and could not re-fetch the primary. The capture's
own closing note flagged the gap: the AsTeR audio quotes need "double-checked before
publishing."

**Why it matters.** This is a Tier-1 technical-mechanism note, and its whole content
is the exact wording of how AsTeR mapped structure to sound. A paraphrase drift
("higher pitch" vs the literal "audio dimension" framing; "distance" vs "falling off
into the distance") would change what the note can be quoted for. It also anchors the
cross-time convergence note
[[observation-math-sonification-pitch-for-vertical-recurred-1994-2024]].

**What would answer it.** Fetch node72.html (and adjacent thesis pages on audio
formatting), confirm both phrases verbatim, capture the surrounding sentences for the
subscript-in-superscript disambiguation (reduced pitch / "head-size" step), and lift
the note's `audit_status` from `capture-verified` toward `verified-verbatim`. If the
page has moved, try the Wayback Machine.

**Answered 2026-07-19** (cross-model audit, claude-fable-5, logged in
`00-meta/audits/audit-scheduled-2026-07-19-fable-1iso4.md`). node72.html resolves
live ("Producing audio notation for mathematics"); fetched twice with independent
transcription prompts, identical wording both times:

- Superscripts: "A change along the audio dimension shown in fig:superscript
  produces a higher pitched voice." — the capture had silently elided "shown in
  fig:superscript"; the claim-note's quote is now corrected to the full sentence.
- Nesting: "As deeper levels of nesting are entered, the change in voice
  characteristic produces a sense of falling off into the distance." — verbatim
  as captured.
- Subscript-in-superscript: "The step size along both the average-pitch and
  head-size dimensions are reduced. This allows unambiguous rendering of
  subscripts in superscripts." — the dimension is "average-pitch," not the
  capture's paraphrase "reduced pitch"; claim-note body adjusted.

The claim-note's `audit_status` now carries an appended `verified-verbatim
2026-07-19` entry; the original capture-verified wording is preserved above it.
