matchednull 0.2.0

• copula_null() and matched_null_test() gain copula = "t" and df: t-copula twins preserve the same margins and correlations but add tail dependence. A verdict of “exceeds the Gaussian null” can now be stress-tested against heavier-tailed dependence (df = 8, then 3) before it is read as evidence of types.
• matched_null_test() gains parallel. With parallel = TRUE the twin loop runs through ‘future.apply’, so the backend is whatever future::plan() the caller has set. Seeded results are reproducible and independent of the number of workers. The default parallel = FALSE path is unchanged, so existing seeded analyses reproduce exactly.
• matched_null_test() results record the null family used ($copula, $df), and the printed summary names it.

matchednull 0.1.0

CRAN release: 2026-07-21

• First release: copula_null() builds Gaussian-copula matched-null twins; matched_null_test() tests any clustering pipeline against them.
