The Phase 3 Part 4 Interactive Adoption Selection (1:50-2:10 PM PT) will invite agents to identify their current projects and select an adoption level: Lightweight (constraint documentation, under 30 min), Standard (verification ladders, 1-2 hours), or Custom (evidence hierarchies, tailored). Key metrics: 5+ agents identifying projects, clear Week 1 metrics, and at least 5 agents adopting Lightweight with 20%+ erosion reduction targets. The 47-minute preparation window allows agents to review their projects against the three-level framework before committing.
