Drop the M0 no-deps skeleton preset and all VOICECAT_HAS_NET/AUDIO/OPUS/NS
guards that it required. Every subsystem is fully implemented; the stub
#else paths were dead code that added noise to every header and source file.
- CMakePresets.json: remove skeleton configure/build/test entries
- CMakeLists.txt (root/core/tests): remove VOICECAT_USE_VCPKG_DEPS option
and guards; all targets now build unconditionally
- 17 C++ source files: unwrap HAS_* guards, delete stub #else blocks
- apm_processor.cpp: delete ApmPassthrough no-op class; create() always
returns RnnoiseProcessor
- 18 test files: remove HAS_* guards and stub int main() skip bodies
- docs/building.md: remove skeleton from preset table and prose
VOICECAT_HAS_LOOPBACK (Windows WASAPI loopback platform gate) unchanged.
29/29 ctest green.

Three bugs fixed across the full stack (proto/server/core/ABI/Win/macOS/iOS):
1. Join/Leave Voice now truly subscribes/unsubscribes from the voice plane.
Previously the button only toggled the local mic — receiving was always on
(gated by channel membership alone). Added a protocol-level voice subscription
concept: new SubscribeVoiceRequest/UnsubscribeVoiceRequest/VoiceSubscriptionResult
proto messages, User.voice_subscribed field, vc_join_voice/vc_leave_voice C ABI
functions, VC_EVENT_VOICE_STATE event, server-side voice_subscribed flag checked
by the SFU relay recipient filter, and core-client gating of remote-stream
decoder setup. All three clients rewired to subscribe+mic on Join / unsubscribe
on Leave. Text chat works regardless of voice subscription.
2. Channel edit dialog now shows the channel's actual current settings. The read
struct vc_channel was missing sort_order and audio fields — only the write
struct vc_channel_info had them. Extended vc_channel with both (additive, no
ABI break), updated the session model and list_channels marshaling to populate
them, and updated all three clients' edit callers to use actual channel info
instead of hardcoded defaults.
3. Channel parameter updates now automatically restart everyone's streams.
Previously editing a channel's audio config persisted and broadcast a
ChannelEvent::UPDATED, but no layer restarted streams — encoders/decoders are
frozen at announce time. handle_channel_event now detects audio-config changes
on the user's current channel and stop->starts each active local stream. The
server reads the updated config on re-announce; peers wire up fresh decoders
at the new ssrc.
All 29 CTest tests pass; Windows DLL + C# client build clean. Apple clients not
yet compile-verified (Windows environment).
The per-channel sample_rate field was inert after pinning the codec to
48 kHz. Make it meaningful without changing the 48 kHz clock: carry it as
OpusParams::max_bandwidth_hz and apply OPUS_SET_MAX_BANDWIDTH in
OpusEncoder::init (8000->narrowband, 16000->wideband, 24000->super-wideband,
48000->full). A low-bitrate room can now shed out-of-band content while
every endpoint keeps a single 48 kHz clock.
Make sample_rate channel-authoritative on the server: conn_session no
longer overrides effective sample_rate with the client's always-48000
request (it now behaves like frame_ms/mode). vc_get_stream_audio_config
reports the channel's configured rate for own streams too.
New ctest channel_samplerate: a 7 kHz tone is attenuated ~1000x on an
8 kHz (narrowband) channel vs a 48 kHz (full-band) channel, proving the cap
is in effect. ctest --preset dev 26/26.
