PolynomialShift(b,c,L,d,e)

Copy the actual length-L decoded prefix and append a genuine zero at index L. The target length is S L. This is multiplication by X, not harmless leading-zero padding. Primality, canonical bounds, covariance and formal equivalence are not clauses of this graph. Raw beta codes and later entries remain unrestricted.

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.

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