# Host-side unit tests for ADR-081 pure-C logic.
#
# These tests exercise adaptive_controller_decide() and the rv_feature_state
# helpers (CRC32, finalize) using plain gcc/clang, with a minimal esp_err.h
# shim. No ESP-IDF, no FreeRTOS, no QEMU required.
#
# Usage:
#   cd firmware/esp32-csi-node/tests/host
#   make
#   ./test_adaptive_controller
#   ./test_rv_feature_state

# Pure-C sources under test. We compile only the files that have no
# ESP-IDF dependency in their bodies: rv_feature_state.c is 100% pure.
# adaptive_controller.c uses FreeRTOS for the timer plumbing, so for the
# host test we compile only the decide() portion by isolating it in a
# small unity file (TEST_ADAPT_PURE below).

# adaptive_controller.c pulls in FreeRTOS headers that don't exist on
# host; we include its decide() function by defining TEST_ADAPT_PURE
# before including the .c. The decide() body itself has no ESP-IDF deps.
# Simpler: just recompile decide() here via a small shim.
