// Note: Fast arrays are deterministic with little seed entropy (usually 64bits, sometimes 32bits).
//
// Wont mitigate; use the slower non-fast variants if each numeric value (if not vec) OR
// a *group* of N-components of each vector (if vec) need to be unique.
//
// Fast arrays simply rehash the previous bits to get the next component. While hopefully
// perfectly uniform (otherwise the hash wouldn't be a good hash), it's entirely possible
// to extrapolate the next value in the sequence.
//
// In addition, this applies to non-fast components of each vector; given an X component,
// you can derive the Y and Z, even under non-fast functions. Fast vectors means the next
// vector can be extrapolated from the previous group of vector components; nonfast, you
// can only solve Y and Z. Fast vector arrays only have 64bits of entropy extrapolated to
// 52bits * uCount * N bits of fully deterministic components; nonfast vector arrays have
// 64bits * uCount bits of entropy, extrapolated to 52bits * uCount * N bits of partially
// in-vector extrapolatable bits.
//
// Also note, it might not even be possible to extrapolate these components in practice.
// This is because each component has some bits chucked away when shoving the seed into
// the mantissa, and then each component gets manipulated using the same range provided
// by the bound[..]s or min/max vecs parameters. Some bruteforce would be required.
