// parent: What the local record looked like the last time we wrote the
//         record to the Sync server.
// local:  What the local record looks like now. IOW, the differences between
//         'parent' and 'local' are changes recently made which we wish to sync.
// remote: An incoming record we need to apply (ie, a record that was possibly
//         changed on a remote device)
//
// To further help understanding this, a few of the testcases are annotated.
