Define process performance measures, KPIs, and compliance controls for a validated PNS. Use this skill when the user needs to add measurability and governance to a documented process; when they ask to define KPIs, set performance targets, add compliance controls, or map the process to a control framework. This is a recommended extension skill — use after okhp3-process-narrative-authoring when governance and measurement rigour beyond the PNS's own kpis section is required. Produces a measures register and a controls register.
