namespace	native
	Architecture-tagged vectors, register packs and supporting value types. Native arithmetic follows its architecture tag and instruction-set preconditions. Common utilities do not select or admit a runtime CPU profile.

	Evaluate the binary32 range-reduced exponential approximation. Degree selects a polynomial from one through seven, defaulting to six. Every degree shares range reduction and exponent scaling; none promises correctly rounded exp for every input. Flush selects the early underflow cutoff at compile time; it does not change CPU controls or turn a raw vector into a policy-bearing FTZ type.
