Endpoint request contains a token. Server checks whether it has enough entropy to be secure (at least 128 bits and >0.7 shannon heterogeneity). Server hashes the token (once as of now) and derives nickname and robohash avatar (goes into static/assets/avatars). Nickname is limited to only adjectives, nouns and 3 digits, restricted to 18 characters long max. The corpus of nicknames is 20 billion big (maybe not enough? nick collision chance can happen, but server will just reply with 400 unless the token matches perfectly too)
Added the Order model with a rough approxiation to the fields needed. The field status can be read lineally as the progression trough the app pipeline. The view serves POSTs requests to enter new orders into the db.
