data(big5) now ships 50 x 4096
Qwen3-Embedding-8B item embeddings (rounded to 4 decimal
places), replacing the 50 x 384 all-MiniLM-L6-v2
sentence-BERT embeddings of 0.1.0. Analyses run on the bundled data will
differ from 0.1.0.sfa_item_fit() now compares candidates against
unflipped (topical) construct centroids, matching
sfa_anchor() and sfa_simplify(). The previous
behavior sign-flipped reverse-keyed reference items into anti-topic
vectors, which depressed the item-similarity profile of constructs with
many reverse-keyed items and could misassign candidates.
reverse_key = TRUE still flips the candidate itself.sfa_congruence()’s disattenuated metric now returns
NA with a warning when either similarity matrix’s
split-half reliability is not positive (e.g., the checkerboard sign
pattern of atomic_reversed), instead of failing with an
unhelpful error.sfa_nli_matrix() reads the entailment/contradiction
label order from the cross-encoder’s model config instead of assuming
the cross-encoder/nli-* order, so non-default NLI models
score correctly (a warning falls back to the default order when the
config is unavailable).sfa_parallel() now applies Horn’s sequential retention
rule (count leading eigenvalues until the first falls below its null
percentile) instead of counting all eigenvalues above their pointwise
percentiles, and its documentation cites the embedding-benchmark
precedent (Garrido et al.).sfa_dimselect() default encoding is now
"atomic", matching sfa().$transformed_embeddings (previously
$embeddings, which was easy to confuse with
$input_embeddings).digest moved from Suggests to Imports: embedding cache
keys are now always SHA-256 (the previous fallback hash could
collide).sfa_anchor() help no longer claims
items are sign-aligned before anchoring (they never were in this release
line, by design), the big5 item-code range reads E1–O50,
the README encoding table marks atomic as keying-free, and
README/vignette references to the bundled data name the Qwen3
embeddings.sfa() function for semantic factor analysis.atomic_reversed, atomic,

They may not be fully stable and should be used with caution. We make no claims about them.
