# Chanora Product Decision Register

**Document status:** DV meeting baseline candidate  
**Date:** 2026-05-29

## 1. Purpose

This register records product and engineering decisions referenced by the DV document set.

## 2. Decision Summary

| Decision | State | DV impact |
|---|---|---|
| DEC-012 legal/trademark/OSS review | Open | Blocks public/store release |
| DEC-020 dual license MIT OR Apache-2.0 | Accepted per README | Supports license posture; dependency notices still require review |
| DEC-027 desktop mouse side-button PTT | Accepted by requirements baseline | Verification must not over-claim unsupported platform input classes |
| DEC-030 VAD deferral | Accepted as deferral | `VoiceActivity` remains disabled/coming-soon |
| DEC-032 Android CMake patch exit path | Active tracking | Patched dependency requires reevaluation |
| DEC-033 macOS VPIO ducking configuration | Accepted | Write `kAUVoiceIOProperty_OtherAudioDuckingConfiguration` with `mEnableAdvancedDucking=0` (disables dynamic voice-activity-driven ducking) and `mDuckingLevel=Min` (= 10) to minimise the ducking of other apps' audio during a voice session; property is macOS 14+ only, the macOS 13 set fails silently (debug log) and VPIO uses its default behaviour; matches the iOS `.voiceChat` baseline on macOS 14+ |

## 3. DV Rule

Open decisions that affect release claims must appear in the waiver register or release-readiness record.
