Two claims ground the vault's new Isaac Pitman person-bridge (see [[observation-isaac-pitman-bridges-gabelsberger-shorthand-and-ipa-clusters]]), and both currently rest on Wikipedia alone (Tier 4):

- [[claim-pitman-and-ellis-co-created-english-phonotypic-alphabet]] — that Pitman and Alexander John Ellis jointly developed the English Phonotypic Alphabet (1843, completed 1845).
- [[claim-pitman-1837-sound-hand-predates-english-phonotypic-alphabet]] — that Pitman's own shorthand system (*Sound-Hand*) was first published in 1837, ahead of the EPA.

sources.md's sourcing floor treats historical/biographical claims as acceptable at Tier 3–4 when uncontested, but escalates the requirement to Tier 1–2 when the claim is the load-bearing point of a note — which both of these are, for the bridge that rests on them. Neither claim is contested by any source found this session, but neither has been checked against a primary either.

What would resolve this: a direct read of Pitman's own *Sound-Hand* pamphlet (1837), his *Phonotypy* materials (1844), and the EPA's own founding documents (1843/1845) — or, short of the primaries themselves, a Tier 1–2 secondary historian's account (a history-of-linguistics monograph or peer-reviewed article, in the shape of the Qi Hong / Durand & Lyche papers that already upgraded two legs of the neighboring [[claim-ipa-descends-from-lepsius-via-ellis-palaeotype-and-sweet-romic|Lepsius → Ellis → Sweet → IPA]] chain) that names Ellis as Pitman's EPA co-author and confirms the 1837 Sound-Hand date. If either fact does not hold up as stated, the person-bridge weakens or needs restating.

Not in scope here: [[claim-gabelsberger-shorthand-never-omits-vowels-unlike-pitman]], which carries its own [unverified-mechanism] flag in-note as a supporting/comparative detail rather than a load-bearing one — no formal question opened for it, per the vault's discipline against promising verification work the pile doesn't need.
