has_key

Helps make implicit data assumptions explicit by attaching
keys to flat-file data that error when those assumptions are violated.
Designed for CSV-first workflows without database infrastructure or version
control. Provides key definition, assumption checks, join diagnostics, and
optional drift detection against reference snapshots.
