- The sample response returns requirement citations and a JSON Patch, then asks the caller to rerun the check.
Field notes
The page lists 27 current requirements, each with a citation and effective date, plus 11 superseded versions kept for history. Its example response separates pass, fail, and needs-review results, then supplies a JSON Patch and verification result; the site also describes an MCP setup intended to learn checkout, brand, plan, and policy details from a codebase.
