brief-architect

Create or revise a durable ArtifactBrief for a formal handoff, repeatable acceptance contract, multi-specialist artifact or explicitly requested PRD. Preserve evidence policy, protected invariants, unresolved material choices and brief/rubric identity. Do not use for ordinary clarification, a clear request to produce the artifact, general planning, product discovery, candidate scoring or a consequential decision. Use when the user requests a brief before execution or a downstream receiver requires this contract.
