TrajectoryOS Desktop Architecture

TrajectoryOS Desktop is a Tauri-based application that serves as the unified control center for personal trajectory management. The application combines life state physics modeling, skill tracking with decay algorithms, voice capture integration, and text-to-speech capabilities into a cohesive desktop experience. The system operates on a local-first architecture where all data remains on the user's machine, synchronized through SQLite databases and connected via the Model Context Protocol for external tool integration. The application is built using Rust for the backend runtime and React with TypeScript for the frontend interface. Tauri provides the bridge between these two worlds, exposing Rust functions as invokable commands that the frontend can call asynchronously. This architecture enables native performance for compute-intensive operations like physics calculations while maintaining the flexibility of a modern web-based user interface. At the core of TrajectoryOS lies a physics-based model of personal progress. The system conceptualizes an individual's life trajectory as a particle moving through a gravitational field, where escape velocity represents the threshold needed to break free from stagnation and achieve meaningful progress. The escape index quantifies how close one is to achieving this velocity, computed from three primary forces. Thrust represents the positive momentum generated through deliberate action, skill development, and goal achievement. The system calculates thrust by aggregating contributions from active skills, completed milestones, and positive life events. Each skill contributes thrust proportional to its level multiplied by an alignment factor that measures how well the skill serves the user's declared objectives. Gravity embodies the resistive forces that impede progress. This includes skill decay over time, unresolved blockers, missed deadlines, and the accumulated weight of incomplete goals. The gravity calculation considers both the magnitude of these impediments and their temporal proximity, with recent negative events contributing more strongly than distant ones.
