gram-struct — per-language grammatical fact sheets

One JSON per language, fused from every source the lexeme-aligner already has, split into four provenance partitions so that licensing is a directory boundary. Design and contract: docs/architecture.md §2. Built by python3 -m lexeme_aligner.gram_struct --build; never hand-edited.

partition	license	contents	provenance
external/	CC-BY-4.0	direction slots + existence facts	Grambank v1.0 (Skirgård et al. 2023, CC-BY-4.0; Glottolog for the Glottocode→ISO mapping, CC-BY-4.0) and WALS (Dryer & Haspelmath 2013, CLDF v2020.5, CC-BY-4.0). Every fact cites its source codes (GB074, WALS:85A).
imputed/	CC-BY-SA-4.0	direction slots only	lang2vec / URIEL syntax_knn (Littell et al. 2017, CC-BY-SA-4.0) and URIEL+ (Khan et al. 2025, CC-BY-SA-4.0; adposition/object_verb only, the slots that cleared 90% agreement with Grambank) — kept physically apart because share-alike applies to derivatives of these values.
derived/	CC0-1.0	our own alignment statistics: direction slots adposition (+ adposition_word: is the adposition a separate word), possessor, subject_verb, object_verb, each with per-edition votes (editions, agreement); article_bound (is the definite article fused into the noun, see article_bound.py); the constituent-order profile; audit.multiword_rates	computed from this project's eflomal(+gloss) alignments of every edition of the language, MACULA syntax only (no BHSA-derived field); no source text redistributed. Agreement with Grambank where both exist (2026-10-08): adposition 92.6% (n=390), possessor 91.7% (n=192), subject_verb 88.6% (n=332 — inside the 85-90% experimental band of the project's admission rule; no alignment mechanism reads it), object_verb 93.5% (n=92); with Östling & Kurfalı's projected word order (2023): adposition 93.9% (n=212), subject_verb 100% (n=711), object_verb 99.5% (n=202) — a correlated method (both project from Bible alignments), reported as a consistency check, not independent proof.
measured/	CC0-1.0	mechanism verdicts, dated, gold named	human-recorded after scoring against gold; never inferred.
kin/	CC-BY-4.0	direction slots only, gap-filling	Glottolog genetic relatedness (bcv-query's languages.db) — the nearest external/imputed-resolved relative's value, lowest priority, structurally unable to override anything else; confidence is a leave-one-out band rate, not the individual fact.
<iso>.json	mixed (see above)	the merge of the five	convenience view; identical content, one file.

Contract

• A slot with "direction": null and a source is a fact: the source knows the codes and they resolve to no single side (e.g. Hindi article: GB022 = GB023 = 0). An absent key means unknown: no source covers this language for this slot. Consumers must gate on the difference.
• Existence facts carry flagged (the polarity's own meaning, from analyze_language.RISK_RULES) and present (the plain reading), plus polarity, codes, known, matched.
• derived/ changes whenever the alignments are regenerated and carries content_sha256; measured/ changes only when a human re-measures and re-dates an entry.
• No field in any file is computed from another field in the same file.
• Merge priority per slot: external > imputed > derived > measured > kin. _coverage.json → merged_slot_sources says, per slot, which partition (or which external source) the merged view took, and how many of those values are a null-with-source.
• Not derivable from alignments, so not here: numeral classifiers, evidentials, tone/phonology, whether a bound form is an affix or a clitic written together (an alignment sees tokens; "fused" is the most it can say), reduplication.
