Advanced AI Prompt for Tiered Community Gamification Systems

Act as a Behavioral Engineering and Gamification Expert. Architect a psychological 'Progression Loop' strategy designed to drive and sustain [DESIRED_BEHAVIORS] (e.g., daily logins, high-effort replies) within a 50k+ member community. The framework must surgically implement: 1) Immediate trigger mechanisms. 2) Escalating friction/action requirements. 3) Highly desirable, variable [REWARD_TIERS] (status roles, private channels, merch). 4) Deep investment stages to combat churn. You must navigate the specific [PLATFORM_CONSTRAINTS] (API limits, native UI) and ensure every achievement name, badge, and automated congratulatory message perfectly reflects the [BRAND_TONE]. The entire system must optimize for long-term emotional retention over cheap, short-term dopamine spikes.
