H12 Configure a local target

Goal: Describe storage without writing.

Prerequisites: H09; dataraft.adapters.

The RDS adapter manages versions in a directory. Its constructor only describes the target.

training_step(
  "H12",
  {
    rds_path <- file.path(training_root, "policies-rds")
    rds_target <- dataraft.adapters::dr_target_rds(rds_path)
    rds_product <- prepared_product |> dr_set_target(rds_target)
    rds_trial <- dr_run(rds_product, write = FALSE)
    stopifnot(!dir.exists(rds_path))
    print(rds_trial)
  },
  needs = c("H09"),
  packages = c("dataraft.adapters")
)

Expected result: The check-only run creates no output directory.

Task: Why explicitly set write=FALSE?
