  📍 **clarify 'MsgFailedToParseGenesis' with regards to which genesis file is expected**
    We wrote that message a while ago when there was only Byron and therefore a single genesis file. With Shelley (and later Goguen), there's now an ambiguity when speaking about 'a genesis file' so it is better called out explicitly.
