NuBerea/unified-grammar

Unified Distributional Grammar (Greek + Latin + Hebrew)

NuBerea/unified-grammar — the j-layer construction × function × source × era matrix, mirroring the shape of NuBerea/distributional-lexicon (lemma × sense × source × era) for grammar instead of lexicon: every grammatical claim scoped, counted, basis-carrying (see METRIC SEMANTICS below), and traceable to corpus instances, with traditional grammars (Smyth, Gesenius-Kautzsch-Cowley, Allen & Greenough) admitted only as witness prose, never as evidence. Full design: grammar/plans/DISTRIBUTIONAL_GRAMMAR_PLAN.v2.md.

This repo replaces the plan's placeholder name distributional-grammar — the owner-chosen repo name is unified-grammar throughout.

Config consolidation (2026-08-24, owner GO 2026-08-23): the per-language greek_* / latin_* / hebrew_* / nt_* / ot_* / lxx_* configs (30 total) were merged into 11 cross-language configs (construction_candidate, construction_gold, construction_judgment, construction_cell, construction_apparatus, grammar_claim, grammar_source_claim, parser_calibration, alignment_positions, projected_heads, latin_syntax_silver_merged), each carrying a lang (or, for latin_syntax_silver_merged, parser_id / calibration_version) column as the discriminator instead of a config-name prefix, built by scripts/build_consolidated.py. The 30 retired per-language config names are tombstoned (status: deprecated) in ontology/manifest/assets.yaml with successor pointers to the merged config; nothing was dropped -- see each merged config's manifest notes: for the exact per-source row counts and column-harmonization list (e.g. gold_definiteness, examples, calibration_version). construction_ontology, greek_syntax_silver, hebrew_gold_heads, hallmark_loci, and crosslang_construction_alignment were not part of the consolidation and are unchanged.

Namespaces

Configs are namespaced greek_ / latin_ / hebrew_, plus unprefixed crosslang_ for the one cross-language config — exactly NAMING_CONTRACT.md rule 1 from the lexicon family (a config that ships to another repo keeps that repo's own real name, never a lang-prefixed alias; construction_ontology itself is also unprefixed, since it is the shared language-neutral inventory both arms key against).

Only construction_ontology is real today; every other row is a routing stub that exits NOT_IMPLEMENTED: <config> (rc=3) rather than emit fabricated data — see build.py's module docstring and VERIFY.md.

Upstreams

Live, already-on-platform (no new intake needed for Phase 0): macula-greek, macula-sblgnt-syntax, macula-hebrew, macula-hebrew-syntax, septuagint-lxx, vulgate-clementina, features/grc_syntax, features/lat_syntax, classical-greek/grc_segments, distributional-lexicon (lexical-class covariate).

Planned t0 repos (owner-gated creation, per-repo confirmation — see plan v2 §2, §8): papygreek-treebank, agdt-treebank, pedalion-treebank (Greek gold treebanks, Phase 2), latin-llct-treebank, latin-udante-treebank, latin-circse-treebank (Latin gold treebanks, Phase 3), allen-greenough-grammar (Latin grammar witness, DCC re-edition, CC BY-SA 3.0, Phase 1), gesenius-kautzsch-grammar (Hebrew grammar witness, Wikisource, CC BY-SA 4.0, flagged incomplete, Phase 1).

smyth-grammar — UNBLOCKED 2026-08-23 (owner ruling): Smyth 1920 is public domain; the Perseus/ Alpheios CC BY-NC-SA claim attaches to their encoding, which is not redistributed. NuBerea/smyth-grammar (k=public-domain, 3,261 sections §1–§3048 + 213 dialect paragraphs, 658-row TOC; built from the Perseus-derived neelsmith/smyth TEI, Beta Code → Unicode) is the Greek grammar witness; greek_grammar_claim / greek_grammar_source_claim can now be implemented against it (plan v2 §8 D6 superseded).

k / licensing

• construction_ontology: k: curated — the owner-ratified 20-construction seed table, hand-authored, language-neutral, holding grammar_crosswalk section-NUMBER pointers only (never grammar prose).
• Every derived {lang}_* and crosslang_* config: k: computed once implemented — t = max(upstream t) + 1.
• {lang}_grammar_prose (not yet a config in this repo's CONFIGS_BY_LANG — ships from the individual grammar-witness t0 repos per plan v2 §3) carries the true source-license province via the license-home exception, mirroring greek_lexica_prose.

k_firewall (applies to every {lang}_parser_calibration config, present and future): "Ships construction ids, counts, scores, confidence and section-number pointers only — no treebank tokens or grammar prose redistributed or reconstructible." This mirrors the estate's edition_delta / greek_lexica_prose firewall pattern (samaritan-pentateuch-gall / dss-levy precedent): NC-licensed treebanks and benchmarks (Gorman, UD-Perseus, UD-PROIEL, GLAUx's NC layer, UD_Latin-ITTB/Perseus-LDT/PROIEL, LASLA, ETCBC BHSA, UD_Ancient_Hebrew-PTNK) are registered as NC-LICENSED t0 (never-wired) instruments — private, never tenant-wireable, never public or gated-public, never in any config's upstreams: list. Enforced by scripts/grammar_never_anchor_guard.py in build.py --verify: FAIL = no publish.

The witness guard

scripts/grammar_never_anchor_guard.py (transplant of distributional-lexicon's scripts/hebrew/never_anchor_guard.py, which keeps SDBH's CC BY-SA domains from leaking into the CC BY lexicon) asserts:

1. No *_construction_cell / *_construction_apparatus / *_grammar_claim parquet carries a section_id / grammar-work-key column, named or disguised.
2. Every *_grammar_source_claim row has evidence_status == 'grammar-author-claim'.
3. grammar_crosswalk pointers live ONLY on construction_ontology — no other config may carry that column.

Traditional-grammar prose is witness, never evidence: a grammar_explanation tool answer may cite that a construction's function reading is consistent with Smyth §2054 or GKC §116, but no published cell, apparatus, or claim row may be keyed on, or derived from, a section id.

NAMING_CONTRACT policy (plan v2 §4, condensed)

The estate's edition_delta (samaritan-pentateuch-gall / dss-levy) precedent applies verbatim to any future NC-benchmark instrument read in this repo: an exception: {class: instrument-read, reason: ...} block on the manifest node, a k_firewall string stating exactly what ships and asserting non-reconstructibility, k staying the shipping side's true class (never inherited from the NC upstream), and the NC source itself registered as a quarantined instrument — never wired, never an upstreams: entry, never public. construction_id naming is language-neutral by construction (SS5.1/SS5.4 lint in build_ontology.py): no GREEK/LATIN/HEBREW/GRC/LAT/HBO token may appear in a construction id, so the ontology scales across languages without ever encoding a language into the join key itself.

Hard rules honored by this repo

No Hugging Face operations, no git commit/push, no repo creation performed by any script here. No LLM calls inside any builder (stage-prompts-only rule) — the ontology seed is hand-curated, not model-generated. No embedding work, no OCR, anywhere in this repo's scope. assets.yaml and ontology/manifest/schema.py are read-only references for this repo, never edited by it.

METRIC SEMANTICS (2026-08-24)

There is no per-instance confidence in this dataset, and the column names say so. nb_posterior (apparatus) / mean_nb_posterior (cell) is a per-construction naive-Bayes posterior whose only features are genre + the extractor's variables; 16.4% of matched candidates carry no variables at all, so it is a construction+genre base rate — hbo GEN.NN takes 6 distinct values across its 54,260 silver rows (all layers together show 14, because proxy rows carry a re-pointed per-row posterior), hbo CL.PURP exactly one. predominance_share (claims) is a descriptive share of the model's OWN output distribution and is therefore circular as a truth signal.

The measured trust signal is holdout_agreement — leave-one-source-out top-1 agreement — now carried on apparatus and cell rows, not just claims. Read it with n_train_labels/n_train_classes: n_train_classes == 1 means a constant model whose posterior is 1.0 by construction (10 of 47 construction-language pairs), and 5 claims rest on a single training label. hbo INF.ART averages posterior 0.804 across 5,474 rows at a hold-out of 0.1.

On a layer='proxy' row the label came from the adjudicated panel, so a LOW nb_posterior marks model-vs-human disagreement, not doubt — those are the best-evidenced rows here.
