Listing or describing the inputs (4.2) may be needed so users can consult the input documents, so consistency with them can be checked while the plan is maintained, and so changes to them that could call for a review of the plan are spotted.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
