extraction note The device is consistently named 'Transponder Tracking Device' but its acronym alternates between 'TTD' (the majority form) and 'TDD' across multiple books and even within the same book (e.g. b03 uses both on p111 and p200; b13 uses both on p287 and p305). The entity record also lists both 'TTD' and 'TDD' as aliases.
