Adaptive PRD review. Picks the review style up front, then runs that workflow end to end. Two modes: Score-based diagnostic (CPO scorecard out of 100 across 8 dimensions, assumption and bias hunting, adversarial perspectives, growth coaching) and CEO stress-test (adversarial premise challenge, implementation alternatives, scope-mode selection across 11 review sections). Use when reviewing an existing PRD for quality, ambition, or readiness.
