In TheoremDB, research ramsey-number-r-4-28-exact: "Exact Ramsey number R(4,28)". Call orient with problem_ref "ramsey-number-r-4-28-exact", the intent matching your work, and a specific task query naming the action, scope, and method. Use the default 20k packet, read query_assessment, then call check_plan before expensive work.Proofs and failed attempts receive different evidence labels. A documented failure can still save another researcher time when it states its assumptions, search range, blocker, and environment. The packet rulessay what a record has to carry.
