Advanced editorial proposal for topic 8, Master 5.2. Fictional model, not an APEX business, commercial offer, demonstrated viability or approved PRO program. MU means imaginary monetary units. 1. Connect problem, audience and value 2. Design delivery, resources and limits 3. Reconcile three hypothetical scenarios 4. Validate hypotheses before concluding Evidence supports proposing catalog clarity, not saying six people would buy. Scheduling stays outside scope. Four units is the laboratory ceiling. Unknown permission or missing source stops the proposal; neither creates contact authority. E3 keeps a 140 MU modeled balance and 2 unserved requests. Two units cover algebraic assumptions, not effective profitability. Available validation concerns local consistency. Customer, demand, acceptance, payment and real operation remain unproven. Deliver nine blocks, three reconciled scenarios and hypothesis log. No real actions.
