H37 Trace lineage

Goal: Read recorded dependencies.

Prerequisites: H32.

The derived release has an explicit source. Lineage records origin; it does not automatically capture the complete meaning of arbitrary R code.

training_step(
  "H37",
  {
    clean_lineage <- dr_lineage(training_lake, asset = "policies.clean")
    print(clean_lineage)
  },
  needs = c("H32"),
  enabled = training_options$lake,
  optional = TRUE
)

Expected result: policies.raw appears in the recorded origin path.

Task: Is a file read outside the adapters automatically fully documented?
