Three claim-notes promoted 2026-07-09 —
[[claim-barbier-night-writing-designed-for-blind-not-soldiers]],
[[claim-braille-barbier-first-met-1833-after-braille-published]], and
[[claim-barbier-universal-phonetic-literacy-ambition]] — all rest on a single
directly-read source: Philippa Campsie's parisianfields.com essay (Tier 2, an
expert's popular account of her own archival research). The peer-reviewed
version ("Charles Barbier: A hidden story," *Disability Studies Quarterly*,
2021) and the Perkins School account both returned HTTP 403 during the capture
session, so the archival basis was never read at the primary level, and the
notes are held at `seedling` / `capture-verified`.

Two distinct verifications are needed.

**Why it matters.** The whole thread is a myth-correction; a myth-correction
resting on one un-re-read blog post is only as strong as that post. And the
correction's most vivid mechanistic detail — *how* the false story spread — is
currently unverified, which is exactly the load-bearing part of a citogenesis
argument.

**What would answer it:**

1. **Primary-level read of the correction.** Reach the DSQ 2021 article via an
   alternate route (Wayback Machine, institutional access, or a stable mirror)
   and confirm, against Campsie's own citations, (a) that Barbier's 1815 *Essai
   sur divers procédés d'expéditive française* frames the system for blind
   people, (b) the ~two-days-of-1792 military service detail, and (c) the 1829
   publication / 1833 first-meeting chronology. This would lift the three notes
   off `capture-verified`.
2. **The transmission chain.** The capture's flagged
   `[unverified-historical]` lead alleges that Pierre Henri's 1952 centenary
   biography *La Vie et l'Oeuvre de Louis Braille* speculated about a military
   origin *with a hedge* ("here is roughly how things must have happened"), and
   that local historian Jean Roblin then popularized it *without* the hedge,
   cementing the legend for ~60 years. Read Henri and Roblin (or the DSQ /
   Perkins accounts that summarize them) directly to confirm the hedge existed
   and was dropped — this is the "shared hedges dropped" mechanism the vault's
   citogenesis cluster ([[claim-wikipedia-amari-sgd-citogenesis]],
   [[myth-linnainmaa-uncited-before-2010s]]) would want established rather than
   asserted.

**Candidate next moves.** Try the Wayback Machine snapshot of
dsq-sds.org/article/view/7499 and perkins.org/braille-barbier first; failing
that, look for the DSQ article via an institutional proxy or a citation index.
A separate, still-unexplored hook from the same capture — Alexandre-René
Pignier's alleged fabrication of a Braille–Barbier personal rivalry — could be
chased in the same primary sources while they are open.

**Progress, 2026-07-24 (partial — left open).** A follow-up capture
(`10-inbox/raw/2026-07-23-verify-the-barbier-night-writing-myth-correction-against.md`)
resolved part of item 1 and fully chased the Pignier hook, but left item 2
open:

- **Resolved at Tier 1:** the 1829/1833 chronology, via a 2024 recorded
  UKAAF interview transcript with Campsie (direct quotes) plus the DSQ 2021
  abstract (via a colab.ws mirror — the canonical dsq-sds.org host is still
  walled off). See the updated
  [[claim-braille-barbier-first-met-1833-after-braille-published]].
- **Resolved at Tier 1, and sharpened well past "unexplored hook":** the
  Pignier fabrication now has a source (his post-1840s retirement memoir,
  written after both Braille and Barbier were dead) and a named scene (a
  fictional hostile 1821 exchange). See the new note
  [[claim-pignier-fabricated-braille-barbier-hostile-encounter-in-retirement-memoir]].
- **Still NOT resolved — the sole remaining reason to keep this question
  open:** the specific Henri-1952-hedge → Roblin-unhedged-popularization
  mechanism (item 2). The interview confirms Henri exists, wrote in 1952
  (Braille's centenary/Panthéon-transfer year), and is one of two accounts
  (with Pignier's) the DSQ article corrects — but does not describe a hedge
  or Roblin's role in dropping it. dsq-sds.org and perkins.org/braille-barbier
  were both still behind bot-check walls this session (Anubis and HTTP 403
  respectively), as were Wayback Machine and archive.ph mirrors of both.
  Whoever picks this up next should retry those two URLs first, or find an
  institutional-access route to the full DSQ article.
- Item 1(a)/(b) (the 1815 book's blind-people framing verbatim, and the
  ~two-days-of-1792 military-service detail) remain confirmed only via the
  original parisianfields.com post and its 2026-07-22 cross-model re-fetch —
  still not cross-checked against the peer-reviewed DSQ text or an interview
  quote naming those specifics directly.

Left `status: open`, genuinely partial rather than forced closed.
