Do current US state-level Nemeth-vs-UEB-Math instructional mandates split along the same lines as the 1871-1932 Braille/New York Point standards war?

claim-bana-2012-ueb-adoption-kept-nemeth-code-parallel establishes that BANA's 2012 UEB adoption left Nemeth Code alive as a parallel official code for math/science braille, with no single US mandate — the source capture's hop chain noted this "per secondary sources not independently re-verified" and flagged the state-by-state pattern as "not checked."

The open question: do individual US states' current instructional mandates (which code state departments of education, schools for the blind, or transcription agencies default to for math/science) cluster in any way that echoes the older regional/institutional split between Braille and New York Point adopters (1871-1932), covered at claim-war-of-the-dots-competing-braille-systems-1829-1932? Or is today's split uncorrelated with the historical one — a fresh line drawn on different grounds (curriculum-era, transcriber training pipelines, particular state Blind schools' institutional lineage)?

What's needed to answer this:

• A primary or Tier 1-2 roster of current state-by-state Nemeth vs. UEB-Math mandates (candidate sources: BANA itself, National Braille Association, American Council of the Blind's braille-education committee, or state Department of Education special-education transcription guidance documents).
• A primary historical roster of which US states/institutions adopted Braille vs. New York Point vs. American Braille during 1871-1932 (candidate: APH's own historical archives, or a scholarly history of American braille standardization) to compare against.

Not chased in the 2026-07-09 capture or its promotion; flagged as a genuine gap rather than answered.
