impact-analysis

Analyze the impact of a proposed change across a traceability graph. Names affected artifacts (no 'many'), classifies blast radius (local / cross-team / external / enterprise), scores change-level risk per factor (reversibility / detection / blast / schedule / compliance), estimates effort per team, proposes phased rollout with gates and rollback, plans communication per audience, and surfaces residual uncertainties for discovery.
