This scenario validates genuine two-channel processing around the Apple Podcasts -16 LKFS (+/-1) recommendation and -1 dBFS true-peak ceiling. It is a product-behavior and starting-point check, not a guarantee of platform acceptance. The source fixtures use deterministic stereo placement so the run verifies linked stereo measurement and channel preservation instead of merely duplicating a mono file.
