if (requireNamespace("survival", quietly = TRUE)) {
  library(survival)
  mock_df <- data.frame(time = 1:30, event = rep(c(0, 1), 15), factor = rnorm(30))
  res <- find_cutpoint(
    mock_df, "factor", "time", "event",
    num_cuts = 1, method = "systematic", quiet = TRUE
  )
  p <- plot_cutpoint_residuals(res)
