test_serial mocked log_write.h, which serial.c never calls. Split celrs_serial into celrs_serial (platform-agnostic logic) and celrs_serial_platform (real Win/POSIX backend), matching the celrs_logger/celrs_log_write split. test_serial now mocks celrs/platform/serial_internal.h and links only celrs_serial, so the list-ports tests verify the max_ports clamping and pass-through logic without hitting the real registry or /dev.
