Use when turning a qualified Twenty lead — a call-summary brief plus any client braindump/docs — into a partner brief a partner can scope and quote from. Trigger when pointed at a lead folder (e.g. partners-experience/<LEAD>/) and asked to "draft a design doc", "create a partner brief", "translate this into Twenty terms", "scope this for a partner", or "prep the partner handoff". Default output is zero-inference (only what the client said; empty sections get a placeholder). Pass --full for inference mode. Chains after twenty-lead-intro-call-summary.
