Third edition: UD heads in the human layer, out-of-work selection, work-held-out halves and genre versions, content-masked text
Rebuilt after Referee Report II. The AGDT-lineage trees are converted from Prague-style to Universal Dependencies heads before publication (scripts/prague_to_ud.py; AGDT/UD Perseus head agreement 62.1% -> 95.4%), every coordinator in every project and in the machine layer attaches to the following conjunct, and the markup-only floors now see head geometry. The work-held-out track holds out a second whole work for validation where the author has one, carries the genre of its test work and whether another author of the track writes that genre (nine rivals, three singletons), and gains single-project work-held-out versions of the tragedians and Attic-orators tracks. Every row carries text_distorted, the content-masked text. The hexameter track is renamed archaic_epic. The 100 audited machine trees were annotated a second time from scratch and the two audits compared. The rebuild job now preserves the manual audit directory across rebuilds.

Rebuild the metre publication under the second-edition text rules
The Hypotactic line cache is re-parsed under the current tokenisation, and the span, crop and coverage checks share one text reduction: Greek letters without the archaic numeral letters, which the parser's tokeniser drops. A gold alignment component whose line boundary falls inside a word written across two lines leaves the gold reference with a counted reason instead of aborting the build. The rebuild job takes the cache path from STOICHEIA_CONLLU and builds both publications when SKIP_METRE=0. The sentence publication is unchanged by this commit: it reproduces revision 667319c byte for byte. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>531a22f

Second edition: work-held-out and matched tracks, four splits, two syntax layers
Rebuilt after an adversarial review of the first edition. Every split, chunk boundary and seed changed (seed 917). The 50-sentence task and the source-held-out track are gone; sentence_{1,5,10} is joined by work_held_out_{1,5,10}, whose test split is one whole work per author held out within an annotation project, and by the matched tracks tragedians, attic_orators, imperial_historians and hexameter. A fourth split, validation2, is reserved for choosing combination models. Exact deduplication now ignores modifier letters, passage-level near-duplicate removal follows it, a token is a word only if it contains a Greek letter, and every sentence's text is exactly its published forms. The human trees are published as conllu_human beside conllu_machine, one Stoicheia parse of every sentence carrying the human lemma, with an independent manual audit of 100 trees under metadata/machine_syntax_audit/.

Fold the positional tag into FEATS and stop publishing XPOS
XPOS and FEATS were two representations of one morphological analysis, which is how stale information starts. They had already drifted: each carried distinctions the other lost, and they disagreed on roughly 136,000 tokens. UD's Tense cannot express the Greek tense system. Aorist, imperfect, perfect and pluperfect all read as Tense=Past, so the nine-position tag was the only record of which one a verb was — a distinction that matters for authorship attribution in Greek. It was likewise the only record that a verb was non-finite: 20,798 infinitives and participles carried no VerbForm at all, while others carried a non-standard Mood=Inf. It alone separated the medio-passive from the true middle, which FEATS flattened onto Voice=Mid. FEATS meanwhile was the finer of the two on ambiguous genders such as Masc,Neut. FEATS also contradicted itself, reading pluperfects as Past 837 times and Pqp 354 times. The tag is now folded into FEATS and dropped. All seven Greek tenses stay distinct in s…13ef6e2

Publish structured columns instead of JSON inside strings
The CoNLL-U column was one long string of escaped tabs and newlines, which is unreadable in the Hugging Face viewer and in any Parquet tool. Every column that held JSON in a string is now a real nested Arrow type, so load_dataset returns Python lists and dictionaries with nothing left to parse: row["conllu"][0][0][2] {"id": 3, "form": "βῆ", "lemma": "βαίνω", "upos": "VERB", "xpos": "v3saia---", "feats": "Mood=Ind|Number=Sing|Tense=Past|Voice=Act", "head": 0, "deprel": "root"} A unit is a list of sentences and a sentence a list of tokens, because one Sphragis Metre line can span a sentence boundary; every Sphragis sentence unit holds exactly one. scripts/conllu_units.render_conllu returns canonical CoNLL-U text, and the build validates every published unit by rendering it and parsing the result with the official CoNLL 2018 loader, so the structure is provably still CoNLL-U. Naming the fields once in the schema rather than once per token also makes the data smaller t…31e2783 -
Remove annotation-scheme leakage from model-facing columns
Sphragis merges seven annotation projects whose author inventories do not overlap, so every convention that separates the projects also separates the authors. A classifier seeing annotation markup and no Greek at all reached 63.4% accuracy and 45.3 macro-F1 on the 17-way sentence_1 task against a 14.6% baseline, and single rules were near-deterministic: no PUNCT token identified Herodotus at 99.6% precision over 83% of his sentences, and an empty MISC column separated the Iliad from the Odyssey at 83.5%. Every published column is now reduced to one shared representation: - MISC is cleared; NativeRel, NativeHead and HeadRepair move to a new native_syntax audit column, keyed by published and source token index. - Editorial punctuation tokens are removed and trees re-indexed, because UD PROIEL does not tokenize punctuation at all. - Elision is written as a combining comma by AGDT and UD Perseus, as three different apostrophes within Gorman, and as U+2019 by Pedalion and PROIEL; …6fc8784
