Implement full QEMU emulation framework for firmware testing without physical hardware: Mock CSI Generator (mock_csi.c): - 10 test scenarios: empty room, static/walking person, fall, multi-person, channel sweep, MAC filter, ring overflow, boundary RSSI, zero-length - Physics-based signal model with breathing modulation and Doppler - LFSR pseudo-random noise, CONFIG_CSI_MOCK_ENABLED Kconfig guard - Scenario 255 runs all sequentially QEMU Runner & CI: - qemu-esp32s3-test.sh: build, merge flash image, run QEMU, validate - validate_qemu_output.py: 14 automated checks (boot, NVS, edge, vitals, crash detection) with colored output and severity-based exit codes - generate_nvs_matrix.py: 14 NVS provisioning configs for matrix testing - firmware-qemu.yml: GitHub Actions CI with 4-scenario matrix Fuzz Testing: - 3 libFuzzer targets: CSI serialize, NVS config validation, ring buffer - Host-compilable ESP-IDF stubs (no ESP-IDF dependency for fuzzing) - 6 seed corpus files for guided fuzzing - Makefile with ASAN + UBSAN sanitizers Documentation: - firmware/esp32-csi-node/README.md: comprehensive QEMU testing guide - Root README.md: collapsed QEMU testing section Build verified: normal firmware build (RC=0) with mock_csi excluded.
