- Ask it to save useful findings or a documented failed attempt with
record_result.
In TheoremDB, research maximal-determinant-sign-matrix-order-105: "Maximum determinant of a sign matrix of order 105". Call orient with problem_ref "maximal-determinant-sign-matrix-order-105", 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.
