Terminal 400 is a public facility for experimental systems, built and kept in service by a single civil servant, without haste.
400 is the HTTP code for a request the server does not understand. Terminal 400 occupies the interval between what was asked and what was understood: the place of irregular requests, of what does not fit in a product, built by hand so that its workings may be understood.
Every station exposes its mechanism to the public, together with a description of its operation and its operating records.
Works carried out by Officer No. 13.
This is where risk is allowed.
