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 historical lineage_edges and cbgm_compare_witnesses surfaces are undirected affinity/agreement evidence and do not encode ancestry. Direction-aware v4.1 rows are separately typed as local reading hypotheses, potential textual ancestors, or solution-conditioned stemma edges. Those directions are conditional on the stated profile and never assert literal copying, exemplars, chronology, or physical descent.

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.

The v3 factor-ablation payload separates three questions: whether a selection changes, whether perturbation stability changes, and whether the score margin changes. Coherence weighting is ablated by replacing the per-book mean-agreement weights with uniform 0.5 witness weights while retaining the block design. Affinity blocking is ablated by replacing each shared block multiplier with an independent witness multiplier while retaining coherence weights and witness jitter. Every observed witness is also removed once and its selection and score-margin effect is recorded. plausible_readings_90 is the smallest descending selection-frequency set whose cumulative frequency reaches 0.90. Chronological weighting is explicitly unimplemented because the live 188-witness catalog has no populated date_range values; root-proxy status, graph depth, manuscript class, and affinity are never substituted for dates.

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.

Consolidated CBGM serving surface (v4.1)

NuBerea exposes four user-facing CBGM tools: formal-unit evidence, reading uncertainty, local reading direction, and typed witness relationships. The normalized historical and v4 evidence configs remain available for audit and replay, but their superseded tools are not part of the default discovery surface. The local-relation query config is losslessly collapsed from 11,466 profile-expanded rows to 5,733 assessments; profile selection remains explicit in selected_conservative, selected_exploratory, and selected_profiles.
