Produces the per-feature / per-release risk-matrix artifact itself: a structured intake (feature, category, impact 1-5 by likelihood 1-5, score), mitigations with owners and due dates, supporting both lightweight (impact by likelihood) and heavyweight (FMEA / Cost of Exposure) methods per RBT canon, output as a Markdown / spreadsheet the team reviews each sprint. Use when building the matrix artifact; to facilitate the live risk-storming meeting use risk-storming-facilitator, to calibrate scores across raters use risk-matrix-calibration, and to map the resulting risks onto test coverage use risk-coverage-mapper.
