Address
data class AddressMeta(var guid: String, var timeCreated: Long, var timeLastUsed: Long?, var timeLastModified: Long, var timesUsed: Long, var syncChangeCounter: Long)
Metadata fields managed internally by the library: the guid, timestamps and local sync state. These are automatically set on add_address and updated on operations like touch and update_address. Not included in UpdatableAddressFields; use add_address_with_meta when importing records that already have metadata.
