#
# Phase 9 / TEST-01 / D-37: assert no OpenVR symbols in
# apps/mic_test/src/wav_replay.{hpp,cpp}. Replay harness must remain
# headless — TEST-01 invariant. RED-tolerant via skip-on-NOT-EXISTS
# (passes Wave 0 before wav_replay TUs exist).
#
# Sibling of cmake/AssertDetectionRunnerNoVrApi.cmake (P7 D-22 / SVR-05).
# Mirrors the regex set and aggregation shape — narrowed to a two-file
# explicit list. Wave 0 RED-tolerant: when the wav_replay source files do
# not yet exist (before Plan 09-04 lands them), the lint exits 0 cleanly
# so ctest stays green during Wave 0. Once the files exist, the lint scans
# them and stays green so long as the replay harness avoids OpenVR symbols
# (the canonical invariant — replay must run on the same host CI workers
# that have no SteamVR runtime).
#

#           -DREPLAY_DIR=${CMAKE_SOURCE_DIR}/apps/mic_test/src
