**Version**: 1.4 **Created**: 2025-12-12 **Last Updated**: 2025-12-12 **Status**: 🎉 Core Features Complete → Ready for Production Polish **Overall Progress**: 18/23 tasks complete (78%) ### Vision Transform the TrajectoryOS frontend from a skeleton application (20% complete) into a production-grade life operating system that **replaces traditional calendars** with physics-based trajectory intelligence. ### Current State - ✅ Backend: 95% complete (6 Python models + 20+ TypeScript endpoints) - ⚠️ Frontend: 20% complete (basic Next.js structure, wrong API configuration) - ❌ Integration: Broken (dashboard points to gesture trainer API instead of trajectory-core) ### Target State - ✅ Production-ready web dashboard with real-time physics computation - ✅ Interactive trajectory timeline (calendar replacement) - ✅ Scenario planning studio with visual comparison - ✅ Skill graph visualizer with Bayesian uncertainty - ✅ Full integration with backend Python models - ✅ Type-safe, performant, responsive, and polished ### Success Metrics - [ ] 100% of backend endpoints integrated with frontend - [ ] Real-time data updates (<500ms latency) - [ ] Mobile-responsive design (320px - 2560px) - [ ] 90+ Lighthouse performance score - [ ] Zero TypeScript errors - [ ] Comprehensive error handling and loading states - [ ] User can manage entire trajectory without traditional calendar

Why this is not always a full paper yet

Corpus pages are public-safe readers for discovered workspace artifacts. They are not automatically final papers. A corpus item becomes a polished paper only after the editable source, evidence checkpoints, references, figures, render path, and release status are attached through the paper schema.
