      "topic": "Planar buffer architecture and zero crosstalk",
      "summary": "Transporting uncompressed audio frames as contiguous planar float32 channels rather than interleaved frames prevents memory stride misalignment and eliminates inter-channel digital crosstalk. On stepped single-channel pulses, unmodulated channels maintain strictly 0.000000 amplitude (-144 dB digital isolation floor).",

      "summary": "1-based channel mapping in shader let-bindings and automation uniforms aligns with 0-based native audio capture channels without inversion or byte swapping. Channels 1 through 32 demonstrate strict monotonic modulation across full scale.",
