Changes in version 1.0.0 (2026-08-06)                  

Sixth audit release-gate corrections

  - Replaced substring-based NOTE acceptance with a strict line
    whitelist: only the optional maintainer line and the exact New
    submission marker are admissible.
  - Added internal clean/composite NOTE regression cases so an incoming
    NOTE containing any additional finding blocks release.
  - Strengthened the two-pass roxygen2 gate to compare the complete
    man//NAMESPACE file set before comparing hashes.
  - Refreshed the static audit, validation record, and SHA-256 manifest.

Fifth audit corrections

  - Stabilized the extreme upper-tail Z regression test by comparing the
    p-value with the tail probability evaluated at the statistic
    actually returned by the function.
  - Corrected the paired t-test educational hypotheses to use the
    population mean of the differences, mu[D], rather than the sample
    mean bar(D).
  - Added a two-pass roxygen2 idempotence gate and explicit
    synchronization checks for the chi-square help pages.
  - Strengthened review of the single admissible New submission NOTE by
    printing and saving its complete text.
  - Corrected the static-validation manifest count and refreshed the
    SHA-256 manifest.

Fourth audit release corrections

  - Builds the final source archive with manual = TRUE so the reference
    manual is included in the CRAN release workflow.
  - Allows only the single informational New submission NOTE while
    blocking every error, warning, and unexpected NOTE.
  - Replaced chi-square htest alternatives with descriptions of the
    scientific hypotheses.
  - Replaced tests of internal helpers with tests through exported
    functions.
  - Added a programmatic package-name conflict check against current and
    archived CRAN packages and current Bioconductor repositories.
  - Consolidated the release history under a single version heading.

Third audit release-engineering corrections

  - Added a strict rcmdcheck release gate that blocks on any error,
    warning, or unexpected note.
  - Regenerates man/ from canonical roxygen2 comments before every
    release build.
  - Regenerates README.md from README.Rmd and rejects stale YAML front
    matter.
  - Added PDF-device smoke tests for the plotting branches of all ten
    exported functions.
  - Made spelling and URL checks release-blocking and added a reviewed
    technical word list.
  - Preserved the statistical and interface corrections from the
    previous candidate.

Core statistical and interface corrections

  - Corrected recursive and external-object argument defaults.
  - Added validation for significance levels, alternatives, samples,
    variances, sample sizes, paired lengths, frequencies, and degrees of
    freedom.
  - Corrected the directional F test so the variance ratio remains s2X /
    s2Y.
  - Restricted goodness-of-fit, independence, and homogeneity chi-square
    procedures to the standard upper-tail omnibus test.
  - Corrected the FO/FE pathway in tq2a().
  - Retained fractional Welch-Satterthwaite degrees of freedom in
    tt2d().
  - Replaced statements that treated non-rejection as proof of equality
    or independence.
  - Restored graphical parameters after every function call.
  - Added structured invisible htest-compatible return objects.
  - Added executable help examples, vignette examples, and automated
    testthat regression tests.
  - Removed duplicated installed static HTML and manual test scripts
    from inst/.

Second CRAN-candidate correction

  - Made raw-data and summary-statistics input modes mutually exclusive.
  - Added plot = TRUE to every exported function; tests and most
    vignette examples use plot = FALSE.
  - Replaced subtraction-based upper-tail probabilities with direct tail
    calculations.
  - Corrected both lower-panel F-distribution polygons in tf2().
  - Displayed both lower and upper critical values for two-sided F
    tests.
  - Preserved and aligned named categories in tq2a().
  - Required r = 0 in independence and homogeneity tests while retaining
    the argument for backward compatibility.
  - Re-established roxygen comments as the documentation source of
    truth.
  - Removed the obsolete installed reference to inst/htmlhelp/.
  - Expanded automated tests for summary modes, mixed-input errors,
    alternatives, extreme tails, category alignment, plotting, and F
    critical values.
