# Host test (optional, no ESP-IDF needed)

Compiles the real `main/fingerprint.c` and `main/detector.c` on your PC with a stub FFT and checks
(1) C-vs-Python fingerprint parity on `test_vector.h`, (2) silence/NaN safety, (3) the N-of-M + cooldown state machine.

    python tools/make_template.py --buzz your.wav        # writes main/test_vector.h
    cd tools/host_test
    gcc -Wall -I stubs -iquote ../../main host_test.c ../../main/fingerprint.c ../../main/detector.c -lm -o host_test
    ./host_test
