Declare Unaligned's alignment-one promise in its Rust documentation. Prove
the extracted built-in u8 implementation and exercise generic callers,
callee-proof reuse, a concrete caller, and an unused bound whose law must
remain in the theorem domain. Use that law to prove a zero-free unsafe
NonZeroUsize construction followed by ordinary division. The guarded
standard-library interpretation rejects zero as forbidden execution,
even when a caller discards the result or subsequently diverges.
The concrete byte caller discharges the selected implementation's
law.

Interpret the byte carrier's ABI alignment explicitly as one, checked by
the native compile-time layout fixture. Other carriers retain the abstract
alignment data input. The compiled audit checks that complete interpretation,
so the byte theorem cannot silently constrain every generic alignment.
