  "notes": "frame-wise state model in bounded mean form. Retention states hold the running mean K_t/t instead of the upstream K_t/sqrt(t), so magnitudes stay bounded and a single U16 scale covers the whole recording; the dropped sqrt(t) gain is cancelled exactly by the following affine-free LayerNorm. The graph emits the bounded per-frame increment enc{i}_inc/dec{i}_inc, and the CALLER accumulates mean += (inc-mean)/t in FP32 so quantization error stays per-frame. Caller also feeds inv_count=1/t (encoder) and dec_inv_count=1/t_dec (decoder), and MUST hold decoder state frozen for the first 9 frames (conv warmup) while discarding those preds, matching native StreamingConv1d.",
