"""Remove-AI-Watermarks: Unified tool for removing visible and invisible AI watermarks.

High-level API (lazy, so ``import remove_ai_watermarks`` stays cheap)::

    import remove_ai_watermarks as raiw
    raiw.remove_visible("in.png", "out.png")            # clean a file (provenance auto)
    result, removed = raiw.remove_visible(bgr_array)    # array -> array
    raiw.visible_provenance("in.png")                   # -> frozenset of confirmed vendors
    raiw.identify_video("in.mp4")                       # -> VideoProvenanceReport
    raiw.inspect_video_metadata("in.mp4")               # -> VideoMetadataReport
    raiw.remove_video_all("in.mp4", "out.mp4")          # visible + verified metadata
    raiw.remove_video_batch("videos", "videos_clean")   # complete per-file results
    raiw.remove_video_metadata("in.mp4", "out.mp4")     # verified metadata strip
    raiw.remove_video_invisible("in.mp4", "out.mp4")    # oracle-certified SynthID removal
    raiw.remove_video_visible("in.mp4", "out.mp4")      # stable visible video-mark removal

For a provenance verdict use the ``identify`` submodule::

    from remove_ai_watermarks.identify import identify
    report = identify("in.png")
