test(cond): pin whole-array values through && — copy, keep-old, fallback

An array is one value slot, so a scalar condition gates it as a unit:
the borrowed right side is copied only on the yielding path, and failure
keeps an existing destination, zero-seeds a fresh one, or takes the ||
fallback. Leak-checked via the suite.
