/**
 * @file test_client_driver_loaded_indicator.cpp
 * @brief Phase 8 Wave 0 RED scaffold for IDriverApi::connect() 3-state result (HEALTH-01 / Pitfall 6).
 *
 * Convention: plain-main, exit 0 = pass, 1 = fail. Mirrors
 * tests/test_vr_input_quit_ordering.cpp / driver/audio_worker_lifecycle_headless.cpp.
 *
 * RED until Plan 08-01 lands src/steamvr/include/micmap/steamvr/driver_api.hpp
 * (post-rename of vr_input.hpp; see D-22) with the new ConnectResult enum
 * upgrading the previous bool return on connect(). Build-time fail =
 * Nyquist gate.
 *
 * NOTE on coverage: full ECONNREFUSED-vs-Read-timeout differentiation
 * requires a running stub HTTP server held with `set_read_timeout(0)` to
 * exercise the Timeout branch. This Wave 0 scaffold asserts only the
 * NotFound branch (no listener at all). The Timeout assertion is documented
 * here but skipped at scaffold time; Plan 08-01 lands the impl + grows
 * this test if it lands the timeout-path coverage too.
