Clause 4 asks a team to plan the help, name the audiences, analyse the business use case and record the mobile context before any content is written. The public contents makes clause 4 the planning gate. It starts with planning for mobile devices, then asks for the target audiences, the use case, and the context of use. The context has five parts: a general statement, the technical platform, the screen size, the physical environment and security. That list is the most useful public signal in the draft for a team that is starting work now. It says the mobile setting is not one variable. A help design that works on a large phone, held in two hands, on a fast network, in a quiet room, is not automatically right for a small phone, held in one hand, outdoors, with a locked device. The clause sits before design and development, so a team that starts with the screens has already skipped it.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
