Changes in version 0.1.1 (2026-04-22)                  

CRAN compliance fixes

  - Fixed invalid URL in man/RobustFlow-package.Rd (updated to
    causalfragility-lab organisation).
  - Added inst/WORDLIST to register DII, BAI, TFI as valid
    package-specific acronyms.

                        Changes in version 0.1.0                        

Initial release

New functions

  - validate_panel_data() — validates and prepares longitudinal panel
    data, checks balance, and reports missingness.

  - build_paths() — constructs individual decision paths, computes
    aggregate path frequency counts, the pooled transition matrix, and
    Shannon path entropy.

  - compute_transition_matrix_all() — computes the pooled transition
    matrix across all individuals and all time intervals.

  - compute_drift() — computes the Drift Intensity Index (DII) using
    period-specific transition matrices and the Frobenius norm.

  - compute_group_gaps() — computes group-specific at-event rates and
    pairwise disparity gaps over time.

  - compute_bai() — computes the Bias Amplification Index (BAI), with
    optional standardization, to quantify whether disparity widens or
    narrows.

  - compute_tfi_simple() — computes the Temporal Fragility Index (TFI)
    via scalar hidden-bias attenuation along a user-specified
    perturbation grid.

  - generate_r_script() — exports a self-contained, reproducible R
    script that replicates the Shiny app analysis.

  - run_app() — launches the interactive seven-tab Shiny application.

Interactive application

The Shiny app provides a complete point-and-click workflow with:

  - Data upload and validation (CSV or RDS)
  - Decision path construction and visualization
  - Drift diagnostics (prevalence over time, DII trend)
  - Disparity auditing (group trajectories, gap evolution, BAI)
  - Robustness auditing (TFI, sensitivity curve)
  - Intervention point identification
  - Downloadable HTML report, CSV results bundle, and reproducible R
    script
