Inputs: [DATASET COLUMNS], [SAMPLE ROWS], [SOURCE OWNER]. For each field document type, unit, allowed values, missingness meaning, source and one safe example. Mark inferred definitions for owner review. Output: A column dictionary and unresolved-definition list. Check: Examples conform to the described rules and no private value leaks. If essential information is missing, identify it rather than filling the gap with a guess. For each inferred unit, ask the source owner for confirmation before publishing the definition.
