prime_field_polynomial_trim_input_transport

Alpha v34 independently verified · alpha_closed; checked-use authorized; not Stable

Actual trim witnesses transport under equality of the annotated input prefix, including its zero prefix and genuinely shifted suffix.

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