 The managed client now implements the Swift client's functional surface: profiles and Keychain authentication, TOFU, protected channels, hierarchical channel presentation and roster state, channel and modeless private text, microphone/auxiliary/screen-audio streams, selectable Core Audio devices, VAD/PTT/always-on input, stereo microphone, RNNoise, per-stream receive tuning, self/server mute and deafen, full channel configuration, moderation, permissions, account administration, event sounds and speech. It imports the legacy Swift profile, TOFU and Keychain state during cutover. Capture is converted to interleaved 48 kHz int16 PCM through `AVAudioConverter`; playback converts the shared bounded `PcmRing` into Core Audio's native planar Float32 layout inside an allocation-free, non-blocking `AVAudioSourceNode` callback.
 
-The Swift app remains the release oracle until the managed app passes the manual VoiceOver and real multi-human call matrix. Produce and validate an ad-hoc Release bundle with `zsh clients/apple/dotnet/publish-macos.sh --dry-run`. The script prefers `/usr/local/share/dotnet/dotnet`, where the pinned Apple workload is installed; set `VOICECAT_DOTNET` to override that host. Signing is performed on `bin/Release/distribution/VoiceCat.app`, leaving MSBuild's incremental app bundle untouched. For distribution, set `VOICECAT_CODESIGN_IDENTITY`; setting `APPLE_ID`, `APPLE_TEAM_ID`, and `APPLE_APP_PASSWORD` additionally submits, staples, and Gatekeeper-validates the notarized bundle.
