      LOW

      I have a minimized safe Rust witness for xxhash-rust 0.8.15.

      Safe public route:

      xxhashrust::xxh3::xxh364withsecret(&[0x41], &[])

      The caller-side harness contains no unsafe code. Under release execution, the internal minimum custom-secret length predicate is enforced only by debugassert!. Release-Miri reports construction of a fixed-width reference beyond the empty secret allocation.

      Observed diagnostic:

      Undefined Behavior: constructing invalid value of type &[u8; 4]: encountered a dangling reference

      Local repair evidence: handling custom-secret slices shorter than the internal minimum before fixed-width secret reads makes the same safe short-secret harness pass under Linux release-Miri.
