+/// Pins the exact on-wire bytes produced by Codec.Compose for a representative value of
+/// every TDU family. Esiur is a multi-language protocol (C#/JS/Dart) whose binary format
+/// must stay byte-compatible, so these golden vectors are a guard rail: any later
+/// refactor (e.g. serializer performance work) that changes a single byte fails here.
+/// Values were captured from the current implementation.
