NuBerea NT Textual Analysis

New Testament textual-criticism data over the 188-witness CNTR transcription base, SBLGNT apparatus, MACULA token alignment, and Open-CBGM v2.0 analysis. This query-facing package exposes the formal variation-unit, reading-support, and witness-comparison surfaces alongside the established apparatus and witness tables.

Interpretation boundary

The published lineage_edges rows are undirected textual-affinity edges. They are useful for closest-relative and coherence questions, but they are not formal ancestor/descendant relations. The recovered model contains no reading relations, no potential ancestors, and no directed DOT edges. No directed local-stemma or textual-flow claim should be inferred from these tables.

cbgm_reading_uncertainty is an AI-facing evidence-ranking layer, not the old SBLGNT footnote-presentation policy. Its selection frequencies are deterministic perturbation diagnostics, not calibrated probabilities or confidence intervals. It uses 512 Bayesian-bootstrap draws over heuristic witness-affinity blocks. Rows with fewer than three blocks are marked provisional; single-reading units do not receive a stability estimate. The evidence_requirements payload states the minimum and observed evidence for each datum on each row.

Method v3 makes the sensitivity dimensions explicit. Coherence weighting is ablated against uniform witness weights; affinity blocking is ablated against independent witness multipliers; and every observed witness is removed once. Each factor distinguishes selection change, stability change, and score-margin change. plausible_readings_90 is the smallest descending selection-frequency set whose cumulative frequency reaches 0.90. Chronological weighting is marked unimplemented because all 188 witnesses_public.date_range values are null; root proxies, graph position, manuscript class, and affinity are not substituted for chronology or ancestry.

Configs

Config	Rows	Description
apparatus_full	6,966	Full SBLGNT critical apparatus with variants, witness support, and coherence summaries.
reader_apparatus	1,132	Reader-facing substantive apparatus notes.
reader_apparatus_approximate	87	Reader apparatus notes linked by approximate alignment.
witnesses_public	188	Public witness metadata for the 188-witness corpus.
witness_catalog	188	Extended witness catalog and attestation statistics.
witness_verse_texts	42,482	Per-witness, per-verse CNTR transcription texts.
variation_units	26,065	Evidence-first variation units: a unit wherever >=2 of 196 aligned witnesses (188 CNTR + 8 editions NA28/NA27/THGNT/SBL/WH/Treg/TR/Byz) read differently after orthographic folding, anchored on SBLGNT token spans; readings carry manuscript and edition support, support_tier (edition/multi/singleton), SBL note links, CBGM overlay; 26 explicit coverage rows.
major_edits_curated	28	Hand-curated NT scholarly-seam registry (t0 curated-gold). Its textual entries are also served in apparatus_full as curated_major_edit notes (note_id suffix :cme); this config remains the curated source of record and the curated-locus guard for variation_units.
witness_verse_alignment	42,482	Per-witness, per-verse alignment against the SBLGNT base.
witness_apparatus_links	7,511	Witness readings linked to apparatus and formal variation units.
syntax_graph_index	4,718	Index of SBLGNT syntax graph artifacts.
lineage_nodes	188	Witness nodes with coverage and affinity-graph statistics.
lineage_edges	977	Undirected witness-affinity edges; not ancestor/descendant relations.
apparatus_claim_delta	21,722	Machine-derived claim-impact comparisons for NT apparatus notes.
cbgm_variation_units	2,675	Exact formal variation units with book, chapter, verse, and OSIS anchors.
cbgm_readings	7,024	Greek text and metadata for every TEI reading; 237 defective readings retain explicit engine-exclusion flags.
cbgm_reading_support	16,151	Witness support for every TEI reading; 247 defective support rows retain explicit engine-exclusion flags.
cbgm_compare_witnesses	9,156	Decoded per-book pairwise witness coherence and agreement statistics.
cbgm_reading_uncertainty	2,675	AI-facing coherence-weighted reading selection, perturbation stability, plausible alternatives, explicit coherence/affinity/witness ablations, and minimum-evidence diagnostics for every formal unit.

Formal CBGM recovery

The complete 27-book model was rebuilt with Open-CBGM standalone commit 7e338f2984b77a1f8b49253e1109c289bfd1e0a2 and core commit 2917ba4de5f62f97f59edd451b8c8a6dcb7f134d. It reproduces every published witness-pair/book value (pass, eq, expl, uncl, and perc) and every positive node-extant count exactly. The cbgm_recovery/ directory carries the hash and row-count publication manifest.

Queryable formal surfaces use exact book/chapter/verse/OSIS anchors. Prefer an exact osis_ref predicate for a verse; a trailing wildcard deliberately widens the query to a reference prefix.
