Contest operator name — packed as 5 bits per character (alphabit: space, A–Z, and @ . : / -). Letters are case-insensitive on the wire; unpack uses that bit width. Decode applies the same title-case display rule as MessageCodec.js (not stored on the wire). Full layout: Docs/codec.md in this repository.
