+# Test Recording Outputs
+
+The original `/workspace/testwav.wav` was not changed. These files are listening
+samples, not a claim that the presets have been tuned by listening.
+
+- `testwav.deepfilter-cleaned.wav`: full recording after DeepFilterNet3 at 85%
+  wet strength, mono 48 kHz float WAV, with exactly 5,684,577 frames.
+- `testwav.natural.wav`: the cleaned file through the natural mastering profile,
+  48 kHz / 24-bit mono, measured at -19.11 LUFS and -1.49 dBTP.
+- `testwav.natural.mp3`: 192 kb/s delivery copy, decoded measurement -19.38 LUFS
+  and -1.75 dBTP.
+- `testwav.fft.wav`: the original processed with the explicit non-AI FFT denoiser,
+  for comparison, measured at -19.10 LUFS and -1.50 dBTP.
+- JSON sidecars record settings and technical measurements for each mastering run.
+- `../previews/` contains 30-second natural, narrator and radio samples starting
+  at 10 seconds in the DeepFilterNet-cleaned recording, normalized to similar
+  loudness for comparison.
+
+The container uses musl rather than Arch's glibc. Real CPU DeepFilterNet inference
+was tested using a temporary glibc loader; the cleaned output was then mastered
+with the normal CLI and `--no-denoise`. Therefore the natural report correctly
+lists the cleaned file as its source and `denoiser = none`. This two-step test did
+not exercise the standard Arch installer or CUDA. It also ran denoising before
+highpass filtering, whereas the normal one-command pipeline prepares/filters the
+input before denoising, so a fresh Arch run is not expected to be bit-identical.
+
+On Arch, reproduce the intended one-command workflow with the launcher:
+
+```bash
+./producer.sh process testwav.wav --device cuda --mp3 -o arch-natural.wav
+./producer.sh preview testwav.wav --device cuda --start 10 --duration 30 \
+  --profiles natural narrator radio --output-dir arch-previews
+```
+
+These samples were moved to `lib/archive/` so the checkout root stays clean;
+the files themselves are unchanged.
