Functional Dependency Candidate Keys

Compute attribute closure and all inclusion-minimal keys implied by supplied dependencies.

Compute attribute closure and all inclusion-minimal keys implied by supplied dependencies. One through 12 distinct attributes, at most 64 dependencies. Empty determinant and empty candidate key are allowed when implied. Enumerate at most 4096 subsets in cardinality/input-order bit-mask order; list keys in that order. Logical supplied dependencies only, not an inferred data-quality or normalization certificate. Supplied non-sensitive data only; no live account access, automated changes or certification. Profile 1.0.0: approximate non-integers use 12 significant digits; safe integers and declared integer strings are preserved.
