Visuals are the existing Grave Keeper attack generated earlier through the user's Comfy account. No AI generation, Comfy request, paid download, or credit purchase was made for this sound comparison. Individual attack MP4s preserve the original H.264 video bitstream exactly; only the audio stream changes.

The two-second contextual ambient lead-in uses the previously authored original ambient soundtrack. Pitch changes, equalization, timing, stereo placement, echoes and mixing are recorded in `edit_decision_list.json` and `ffmpeg_commands.json`; the build script is `../../scripts/build_attack_sound_versions.py`.
