Changes in version 0.2.0 (2026-04-04)                  

Breaking changes

  - risk_form_variance_share_fun() has been removed. Its functionality
    is fully subsumed by uncertainty_fun(), which already computed
    identical Sobol' sensitivity indices for all four parameters as part
    of its output. Users should call uncertainty_fun() directly and read
    the sensitivity_analysis list-column from $nodes.
  - Removed the risk_form argument from all_paths_fun() and
    uncertainty_fun(). The additive formula (risk_form = "additive") is
    now subsumed by the unified power-mean formula with p = 1 (default).
  - uncertainty_fun() now returns tibbles instead of data.table objects.
    The data.table package is no longer a dependency.

Bug fixes

  - Fixed duplicate "p" column bug in Sobol sample matrices within
    uncertainty_fun(). The raw column from sobol_matrices() is now named
    "p_raw" internally so the rescaled p column is correctly used.
  - Added @importFrom rlang %||% to plot_top_paths_fun() (previously not
    imported).
  - Added missing @importFrom declarations for
    ggplot2::scale_fill_viridis_c, ggplot2::geom_tile, stats::setNames,
    ggplot2::geom_errorbar, ggplot2::geom_point, and
    scales::breaks_pretty.
  - Fixed fallback nodes_tbl in plot_top_paths_fun() that was missing
    risk_score. The function now requires all_paths_out to be the output
    of all_paths_fun().
  - Fixed \deqn{[0, 1]} in @param of plot_top_paths_fun().

Improvements

  - uncertainty_fun() now returns Sobol' sensitivity indices labelled
    alpha, beta, gamma, and p in the sensitivity_analysis list-column of
    $nodes, replacing the previous internal raw labels a_raw, b_raw,
    c_raw, p_raw. Internally the Sobol' design still draws four
    independent U(0,1) values (required by the quasi-random sequence);
    the raw draws are normalised to weights and mapped to p ∈ [−1, 2]
    before the model is evaluated. The documentation explains this in a
    dedicated Parameter labels and the Sobol' design section.
  - slope_fun() now uses an analytic OLS formula instead of stats::lm().
  - Removed the internal slope_per_draw_from_nodes closure in
    uncertainty_fun() and replaced it with calls to slope_fun().
  - Added shared input-validation helper validate_all_paths_out() used
    across multiple functions.
  - Added eps parameter to uncertainty_fun() for forwarding to the risk
    evaluation.
  - Corrected @return documentation for path_cc in all_paths_fun().
  - Updated inst/CITATION to version 0.2.0.
  - Removed NAMESPACE.bak.
  - Removed redundant !is.na(x) guard in slope_fun() and
    gini_index_fun().
  - Replaced three sequential vapply loops in path_uncertainty_plot()
    with a single pass.
  - Removed trailing blank lines in all_paths_fun.R.
  - Added testthat test suite with tests for slope_fun, gini_index_fun,
    all_paths_fun, and uncertainty_fun.

                        Changes in version 0.1.1                        

  - Corrected the legend name of the path_fix_heatmap function (from R_k
    to P_k).
  - Expanded the vignette to include examples with the power_mean
    formulation.

                 Changes in version 0.1.0 (2026-01-21)                  

  - Initial CRAN release.
  - Functions to compute and visualize risk along software call paths.
