Three corpora seated as one series, because they are one practice at three stages of development. 05/01 Browning, Men and Women (1855), 18 poems, 4,598 lines, Project Gutenberg 17393 — the dramatic monologue, where a poem's speaker first becomes a position distinct from the poet, with a history and blind spots the reader sees past. 05/02 Pound, four volumes all pre-1930 and so US public domain — Personae (1909), Cathay (1915), Lustra (1916), and Poems 1918-21 carrying Homage to Sextus Propertius, which performs in 1919 the manoeuvre Ginsberg later performs on Catullus 38: a Latin source tracked in form and inverted in register, defended as something other than translation. 05/03 Pessoa, the heteronymic corpus from Portuguese Wikisource by declared category — 123 Caeiro, 60 Reis, 107 Campos, 10,540 lines — the only case of the three with documented ground truth, since the letter to Casais Monteiro of 13 January 1935 attributes the heteronyms, making it the positive control for any instrument claiming to detect designed differentiation. The orthonym's 496 pages are deliberately held out so that a leave-one-out test remains possible. Records a technical finding: the Wikisource extracts API silently returns empty for short lyrics whose bodies sit in poem templates, so an extracts-based fetch yields Campos nearly complete and Caeiro and Reis nearly empty while reporting no error; the seat was built from raw wikitext.

Data is published as a sidecar index at api/corpora.json with per-seat links; each seat carries its own source.json and SHA-256 MANIFEST.sha256 at alexanarch.org/data/corpora/<corpus>/, and a rendered reading room at traininglayerliterature.org/originals/<corpus>/. The per-deposit external-metadata sidecar for this record is at /data/external-metadata/AXN-0658.json.
EA-CORPORA-05 seats three corpora that belong together because they are one practice at three stages of its development.
Browning enters at 05/01 with Men and Women (1855). The dramatic monologue is the moment a poem's speaker becomes a position distinct from the poet — with a history, a self-justification, and blind spots the poem lets the reader see past the speaker to. Fra Lippo Lippi and Andrea del Sarto argue their own cases and lose them without the poet ever appearing to judge. The gap between what the voice says and what the poem knows is the whole technique, and it is the ancestor of everything the other two seats contain.
Pound enters at 05/02 with four volumes, all published before 1930 and so public domain in the United States. Personae names the operation in its title. Cathay makes a voice by translating one. And Homage to Sextus Propertius performs, in 1919, the manoeuvre that Ginsberg would later perform on Catullus 38: a Latin source whose form is tracked closely while its register is inverted, defended by its author as something other than translation when the philologists objected that it was a bad one. Pound is the middle term, where the mask stops being a character in a poem and becomes a position the poet inhabits.
Pessoa enters at 05/03 with the heteronymic corpus taken from Portuguese Wikisource by declared category: 123 poems of Alberto Caeiro, 60 of Ricardo Reis, 107 of Álvaro de Campos. The partition is the source's and not the seat's, because that partition is precisely the object under examination and adjusting it to suit a result would destroy the only thing the corpus is good for. Pessoa is the sole case among the three with documented ground truth — the letter to Adolfo Casais Monteiro of 13 January 1935 attributes the heteronyms, so the grouping is known rather than inferred — which makes this the positive control for any instrument claiming to detect designed differentiation.
The orthonym is deliberately not seated. Fernando Pessoa's own 496 categorised pages are held out so that a leave-one-out test remains possible: whether the structure of the remaining voices implies the position that none of them occupies. Seating him alongside would foreclose the experiment. The absence is a decision and is recorded as one.
One technical finding is worth carrying forward. The Wikisource extracts API returns empty text for the short lyrics, because their bodies sit inside poem templates it does not render, while longer prose-poems extract normally. A fetch built on extracts therefore yields Campos almost complete and Caeiro and Reis almost empty, and reports no error while doing it. The seat was built from raw wikitext instead, and the normalization field records why, so that the next attempt does not spend the discovery again.
