FactorListMatching(b,c,d,e,u,v,l)

Each actual source factor equals the factor at the index decoded from its image under the witnessed map.

Conservative notation; not a theorem, primitive, or axiom.

Current library: Alpha v34, 4,223 checked-use theorems; Stable remains 432. Historical first admissions, original proof editions, and non-admitted aliases are preserved. Exact original first-admission records.

The unchanged native kernel never receives this surface symbol. Binder-safe expansion produces only its existing first-order syntax.
