Design a streak-saver mechanism
WHAT IT TESTS: modeling stateful engagement with behavioral nuance. OUTLINE: timezone-aware streak state, capped saver inventory with replenish rules, and A/B testing forgiveness against retention plus guardrails.
WHAT IT TESTS: whether you can model stateful engagement, handle edge cases like timezones, and test a behavioral policy responsibly. ANSWER OUTLINE: store current_streak, last_active_date in the user's timezone, and a saver balance; a saver auto-applies or is offered when a day is missed, subject to caps and replenish rules; A/B test forgiveness generosity measuring D7 and D30 retention as the primary metric with guardrails on session frequency and long-term streak inflation.
