Reduce principles.md from 158 to 73 lines: - Remove duplicates (atomic_commits, tdd, deviation_rules) - Remove version drag from claude_automates - Keep core orientation: solo dev model, plans are prompts, scope control, ship fast, anti-enterprise Add principles.md to 9 core commands so Claude always understands what GSD is.
