TrajectoryOS

**Version**: 1.2.0 **Last Updated**: 2026-01-03 **Status**: Production **Parent**: [00-OVERVIEW.md](00-OVERVIEW.md) **Complement**: [03-ECHELON.md](03-ECHELON.md) (real-time engine) TrajectoryOS is the **operating system layer** that provides long-horizon context, memory, and identity persistence across sessions. While Echelon handles real-time motion physics, TrajectoryOS answers a fundamentally different question: > **What does this moment mean in the context of everything else, and where does it sit in the long arc?** TrajectoryOS operates in a **meta-manifold of trajectories**: sessions, projects, creative arcs, life phases, memory geometry, and symbolic traces. | Aspect | TrajectoryOS | Echelon | |--------|--------------|---------| | **Time scale** | Hours → Years | Milliseconds → Seconds | | **Question** | What does this mean? | What is happening now? | | **State** | Discrete memory turns | Continuous dynamics | | **Output** | Context, style, memory | Control signals, audio | | **Latency** | Seconds acceptable | < 10ms required |
