// The fields in the following wrapper types are all pointers, even when their
// target type is also a pointer, so that they can be used to unmarshal
// directly into the fields of another value.  These wrappers intentionally do
// not omit zero or empty values, since we want the cache to reflect the value
// the object had at the time it was written, even if the default changes
// later.
//
// Moreover, these are all struct types so that each cached record will be a
// JSON object even if the underlying value marshals to an array or primitive
// type, and so that we have a seam if we want to replace or version the cached
// representation separately from the default JSON layout.
