"""Live validation for the issue #70 AutoSyncAudio settings fix.

Connects to a running DaVinci Resolve and confirms, against the REAL resolve
handle (not a FakeResolve), that:
  - the live handle actually exposes the AUDIO_SYNC_* constants the fix relies on,
  - human-readable settings (method="waveform", channel="auto") resolve to those
    live enum keys/values, and
  - unsupported keys (group_id, primary_clip_id) are dropped and reported as
    ignored_settings instead of being forwarded into AutoSyncAudio.

Read-only: it never calls AutoSyncAudio, so no media or project state is touched.

Run:
  venv/bin/python tests/live_auto_sync_settings_check.py
