V16 Rerun after a correction

Goal: Provide prior results for reuse.

Prerequisites: V15.

Unchanged successful branches can be reused. Changed inputs and their consumers run again.

training_step(
  "V16",
  {
    flow_corrected_data <- policies
    flow_corrected_data$premium[1] <- 105
    flow_second <- dr_run(
      training_flow,
      inputs = list(delivery = flow_corrected_data),
      previous = flow_first
    )
    print(flow_second$status)
    stopifnot(flow_first$results$total == 740, flow_second$results$total == 745)
  },
  needs = c("V15"),
  enabled = training_options$extras,
  optional = TRUE
)

Expected result: A corrected total of 745.

Task: What happens to an earlier publication if a later step fails?
