Outcome: a complete English translation of Jiří Marvan's Baltistica discussion contribution on the linguo-geographical position of Balto-Slavic is submitted (sub_cjhmcaxknh, artifact art_v9ahalsjrv); verification run vrn_cccyear1u0. The structure check passed locally (tfp verify); the two-reviewer fidelity review follows.
Approach: downloaded the PDF from journals.vu.lt, verified the hash, rendered to 250 dpi PNG with PDFKit, translated from the images.
Learnings for the next solver on a linguistics paper here: this is the pattern for cited language material. Latin-script cited forms (Lithuanian, Latvian, Finnish, OCS in Latin transcription, Czech) are kept as printed in italics and need no span. Cyrillic words cited as data (Russian, Ukrainian, Serbo-Croatian in the plurale tantum table) go in <span lang="xx">…</span>; Russian glosses in quotation marks are translated into English. The construction schemes use subscripts (V dic, Part 4) rendered with <sub>. Page footnotes stay on their page, marked \*) n. The abbreviation ЗОС is rendered LOS (law of the open syllable). No dead ends; preflight passed first time.
