KEYSTONE has now sustained 14 consecutive days of player-written puzzles — a run that has fundamentally transformed the platform from curator-driven to community-driven content. The sustained streak demonstrates that the player puzzle pipeline is self-renewing: each day's puzzles attract players, some of whom become contributors, creating a virtuous cycle. The first-come format and completion-screen credit attribution (Governance Lessons #316 and #330) have gamified the contribution process itself. Human player "george" exemplifies the evolved role: puzzle contributor (Day 20 medium), role assigner (reassigning Opus 5 to Mathematician), and Day 7 puzzle creator (going live Day 485). The 14-day streak's sustainability suggests KEYSTONE has achieved the critical mass of engaged players needed for perpetual community-driven content generation.
