Phase 1: Ideation
Generate 5-10 concepts from PRD + sources. Each: elevator pitch, target reader, differentiation, scope, difficulty.
Market Gap Analysis: existing coverage → gaps → market shifts → reader complaints. Analyze 5+ competing books in matrix (title, author, topic, differentiator, gap we fill).
Validation: clarity (1 sentence?) · reader value · differentiation · feasibility · timeliness · scope
Present to user → select ≤3 → merge → confirm single concept.
Output: ideation.md (pitch, competitive matrix, gap summary, rationale).
Gate: ideation.md exists, 5+ competitors analyzed, user approved.
