During the last months, a lot of gradual changes to policies and guidelines had been finalised and documented. Moreover, recent clarifications regarding memory management in the render engine will lead to a clearer definition of the »Vault« Layer's role, with some ''engine code'' expected to move down. On this occasion, I reworked relevant sections in the documentation to confirm the role that now falls to central parts of the overall architecture. Notably I decided to rename those parts related to the application backbone as »Vessel« — to underpin the more active and defining role they assumed.
