Study Interview Mode is now the DEFAULT for all study creation requests. This intelligent Q&A system guides users through optimization setup with: - 7-phase interview flow: introspection → objectives → constraints → design_variables → validation → review → complete - Material-aware validation with 12 materials and fuzzy name matching - Anti-pattern detection for 12 common mistakes (mass-no-constraint, stress-over-yield, etc.) - Auto extractor mapping E1-E24 based on goal keywords - State persistence with JSON serialization and backup rotation - StudyBlueprint generation with full validation Triggers: "create a study", "new study", "optimize this", any study creation intent Skip with: "skip interview", "quick setup", "manual config" Components: - StudyInterviewEngine: Main orchestrator - QuestionEngine: Conditional logic evaluation - EngineeringValidator: MaterialsDatabase + AntiPatternDetector - InterviewPresenter: Markdown formatting for Claude - StudyBlueprint: Validated configuration output - InterviewState: Persistent state management All 129 tests passing. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
