The `decodeRef` function used `size > hashLen` to reject oversized embedded nodes, but this incorrectly allowed nodes of exactly 32 bytes through. The encoding side (hasher.go, stacktrie.go) consistently uses `len(enc) < 32` to decide whether to embed a node inline, meaning nodes of 32+ bytes are always hash-referenced. The error message itself already stated `want size < 32`, confirming the intended threshold. Changed `size > hashLen` to `size >= hashLen` in `decodeRef` to align the decoding validation with the encoding logic, the Yellow Paper spec, and the surrounding comments.
