iam-pradeepkumar/AURA-sim ? reverse-engineered prompt

Build me an offline disaster survivor detection system for ESP32s that uses WiFi CSI to sense people in a search area without needing the internet or a router.

I want 4 ESP32 nodes, one sender and three receivers, that form a self contained mesh and can detect motion, estimate a target’s position, track movement over time, and estimate breathing and heartbeat when possible. Please include the firmware for flashing each node, a simple way to set each board’s role and ID, and clear serial output that shows detection results in a human readable way. Also add a simulator I can run on my computer to test the sensing and tracking logic without hardware.

Use the README as the guide for the sensing pipeline and keep it practical for field use. If anything is unclear, look up current ESP IDF docs online and make the project easy to build and run from a fresh clone.
