# Implementation plan

1. Add tests for a stateful network and closed-loop sensory/body behavior. Verify the missing API fails its test.
2. Add the stateful integrator and pure environment simulation, preserving the established solver and input denominators.
3. Acquire pinned Flybody anatomy, decimate it for browser rendering, and vendor pinned Three.js with notices.
4. Add the arena, view controls, direct input/descending/motor readouts, interventions, traces and exports; retain the existing tabs.
5. Check numerical behavior against the real graph, inspect source/assets, update research notes and downloadable package. Commit and push the same source, save and privately deploy the updated Site through Sites.
