Documents the concrete 4-layer development sequence for closing the hardware gap: firmware (ESP-IDF C), UDP aggregator (Rust), CsiFrame→CsiData bridge, and Python _read_raw_data() UDP socket replacement. Builds on ADR-012 architecture and existing wifi-densepose-hardware parser crate. Includes testability path for all layers before hardware acquisition. https://claude.ai/code/session_01BSBAQJ34SLkiJy4A8SoiL4
