# Input file placement

For downstream processing, place the existing Basic trajectory CSVs under `basic/`, using the filenames in `../configs/basic_manifest.csv` or pass the actual path explicitly. These files already contain processed vehicle IDs, lanes, directions, positions, velocities and lengths. The README gives the direct risk/pairing/sampling/inference/interaction commands.

For source detection processing, place the raw detection CSVs under `raw/` using `../configs/source_manifest.csv`. A raw reconstruction lane input belongs under `lanes/` and has `Frame,Vehicle_ID,Lane number,Direction` keyed by original source records. To transfer lane and direction labels from a Basic file, apply the corresponding source/frame/vehicle mapping to the original detection keys.

The processing commands create new files under `runs/` relative to the code directory. Each file's generating command and downstream consumer are listed in the README and `../docs/INPUT_OUTPUT.md`.

All commands accept explicit paths. For combining sources or joining processed IDs, use the established source/frame/vehicle correspondence and offsets.
