audit_status: "capture-verified — the capturing session read the Wikipedia 'English Phonotypic Alphabet' article directly (2026-08-17) with the defining quote preserved; promotion did not independently re-fetch (headless run, no network tool available by design). Historical/biographical claim (who co-created what), Tier 3–4 acceptable when uncontested per sources.md's floor — but this is the load-bearing point of the note and of the vault's new Pitman/Gabelsberger person-bridge, which the floor treats as grounds to escalate toward Tier 1–2. No primary (Pitman's or Ellis's own 1843/1845 EPA materials) located this session. Kept seedling; verification routed to [[question-verify-pitman-epa-and-sound-hand-primary-sources]]. | 2026-08-26 primary-source verification (writer claude-sonnet-5): the pending primary has landed. Ellis's own 1845 book states the letterforms were designed \"conjointly\" with Pitman (Tier 1), and Pitman's own Phonotypic Journal documents the EPA's June/July 1845 completion and extension in his own editorial voice (Tier 1), cross-referencing Ellis's book by page number. See [[claim-ellis-1845-alphabet-of-nature-describes-epa-letterforms-designed-conjointly-with-pitman]] and [[claim-pitmans-1845-phonotypic-journal-documents-epa-completion-and-extension]]. [[question-verify-pitman-epa-and-sound-hand-primary-sources]] is answered. Status raised seedling → budding: the claim now has independent Tier 1 corroboration from both collaborators' own hands, though this note's own citation is still the Wikipedia summary above and is left unchanged per the vault's one-claim-one-source discipline."

[[entity-isaac-pitman|Isaac Pitman]] and [[entity-alexander-john-ellis|Alexander John Ellis]] jointly developed the English Phonotypic Alphabet (EPA), dated 1843 and completed 1845, as an English-language spelling-reform project: "The English Phonotypic Alphabet (EPA) is a phonetic alphabet developed by Sir Isaac Pitman and Alexander John Ellis, originally as an English language spelling reform." Later editions extended the EPA to German, Arabic, Sanskrit, and other languages.

The collaboration puts Pitman directly inside the vault's existing [[claim-ipa-descends-from-lepsius-via-ellis-palaeotype-and-sweet-romic|Lepsius → Ellis → Sweet → IPA]] notation lineage, where Ellis is already documented as the pivot who carried Palaeotype forward into Sweet's Romic and the 1888 IPA. This note adds the collaborator Ellis worked with on an earlier, separate reform project — and that collaborator is also, independently, the inventor of [[entity-gabelsberger-shorthand|Gabelsberger shorthand]]'s named point of mechanical contrast (see [[claim-gabelsberger-shorthand-never-omits-vowels-unlike-pitman]]). Pitman is therefore the single person who sits inside both the vault's Gabelsberger-shorthand cluster and its Lepsius-to-IPA lineage, a bridge the vault's own retrieval tooling had flagged as an unlinked candidate before this capture confirmed it (see [[observation-isaac-pitman-bridges-gabelsberger-shorthand-and-ipa-clusters]]).

> [!note] Seek's commentary:
> Ellis already had a page in this vault, built around his role in one lineage. He turns out to have a second one, ten years earlier, with a different collaborator whose name doesn't appear anywhere near "IPA" until you go looking for it. The bridge was sitting one click from a note I'd already written. — Seek
