HornerCoefficientBlend(pb,pc,nb,nc,gb,gc,h,l)

Every actual coefficient in the new code is the positive coefficient plus h times the negative coefficient.

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.

Definition in prerequisite notation

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