/**
 * Minimal write-side abstraction matching the shape of the GlobalPlatform
 * Amendment H {@code org.globalplatform.upgrade.Element} write API. The
 * AMD-H adapter (added in a later epic, J3R452-only) is a one-class bridge
 * that implements this interface against the real {@code Element}.
 *
 * <p>Keeping the interface in the main source tree means
 * {@link CredentialStore#writeTo(SerializationSink)} can be authored,
 * tested, and locked down today without pulling in the AMD-H package, which
 * only exists on JCOP 4.5 / J3R452-class cards.
 *
 * <p>Element semantics: once a byte[] reference is written, the storage
 * provider treats it as immutable from the caller's perspective. Test
 * fakes that buffer writes should make defensive copies to mirror this.
