MODEL AND DSP COMPATIBILITY
- The first 100 source and 200 target profiles from Beta 0.2.3 remain preserved.
- Stable source and target IDs remain in DAW project state.
- Supported regression sample rates remain 44.1, 48, 88.2 and 96 kHz.
- Same-type filter limits remain +5 dB / -7 dB.
- Cross-type filter limits remain +4 dB / -5.5 dB with 72 percent difference
  strength before frequency-confidence weighting.
- Safety attenuation remains the largest positive filter gain plus 1 dB, with
  at least 0.5 dB attenuation.

BETA 0.6 QUICK REFERENCES
- MY HEADPHONES is the target-off baseline and FLAT is fixed.
- Five numbered slots store exact target profile IDs with empty positions intact.
- Slot assignments are device-level preferences, not automatable parameters and
  not part of the DAW project payload.
- Missing exact IDs remain visibly unavailable rather than being substituted.
- The web tool and plug-in slots are not synchronized in Beta 0.6.

PRIVACY
- Audio, DAW project names, selected models and Quick References are not sent to
  SolAudioLab.
- The optional remote notice reads only the approved SolAudioLab HTTPS text URL
  outside the audio-processing thread.
