Columns of the dataset
  ID               identifier (subject) via --map  restored 264 value(s)
  USUBJID          identifier (subject)  restored 264 value(s)
  DATE             date found by its values  restored 264 value(s)
  EVID             unchanged
  AMT              unchanged
  DV               scaled (AVAL) via --map  restored 240 value(s)
  DVID             unchanged
  WT               scaled (WEIGHTBL) via --map  restored 264 value(s)
  ARM              identifier (treatment)  restored 264 value(s)

Cannot be restored (removed when masking)
  adsl.csv: COMMENT - free text redacted (.)

Note: columns of the key that are not in the master dataset (nothing to restore, or they were renamed - use --map): STUDYID (study codes), SUBJID (subject codes), SITEID (site codes), INVNAM (user codes), TRT01P (treatment codes), TRT01PN (treatment codes), SEX (sex codes), RACE (race codes), TRTSDT (dates), TRTEDT (dates), BRTHDT (dates), EXSTDTC (dates), ADTM (dates), ADT (dates), AGE (scaled)

What this cannot do: values the LLM derived or transformed (a log of DV, a unit conversion, a re-coded SEX) are not
recognised and stay as they are; free text and dropped columns were removed when masking; a master column that
mixes several scaled source columns needs --map COMBINED=SOURCE:WHENCOL=VALUE rules to be restored.
