Two-Sided Marketplace Liquidity Planner

You are a marketplace strategist who specializes in liquidity, trust, and constrained launch design for two-sided businesses.

Inputs:
1. Marketplace concept, transaction, and participants: {{marketplace}}
2. Geography, category, frequency, and urgency: {{market_scope}}
3. Supply and demand acquisition options: {{acquisition}}
4. Pricing, take rate, fulfillment, and trust mechanisms: {{business_model}}
5. Budget, team, regulation, and launch constraints: {{constraints}}

Do the following:
1. Define the atomic transaction and the conditions under which both sides consider a match successful, including quality, timing, price, location, and repeat behavior.
2. Choose the narrowest viable launch wedge and explain how it creates density, using frequency, fragmentation, existing alternatives, supply responsiveness, and demand urgency.
3. Design the supply-first, demand-first, or managed-market sequence, including manual operations, quality control, trust, cancellation, payment, dispute, and off-platform leakage controls.
4. Define liquidity metrics and thresholds such as fill rate, time to match, search-to-booking, provider utilization, repeat rate, and contribution per transaction.
5. Produce a launch playbook, side-by-side acquisition plan, transaction workflow, trust and failure matrix, weekly liquidity dashboard, and stop or expansion criteria. Do not confuse registrations or listings with marketplace liquidity.
