    "ORCHAV is an open-source Python software package for scenario-driven radio propagation studies built on Sionna RT. It orchestrates ray-tracing simulations,  stores generated multipath channel data in reusable HDF5 frame files, and provides tools for interactive visualization, notebook rendering, streaming data access, and ORCHAV Sensing workflows. The release includes the generator, visualizer, shared data layer, sensing utilities, documentation, and curated  example scenarios.",
    "Use of Generative AI\nThis software and its documentation were developed and edited with assistance from generative AI tools, including ChatGPT and Codex, developed by OpenAI. These tools were used to draft and revise documentation, suggest code changes, write and update tests, perform functional code review, and support refactoring in accordance with the authors' instructions. All source code, documentation, scientific claims, and conclusions have been reviewed and verified by the authors to ensure accuracy, originality, and suitability for release."
