Local checkpoint - NOT for public release.
Fan-out (every received stream to every selected output, no added latency):
- SessionPlayout mirror replicas fed the same decoded bytes; delicate ReadFloats untouched.
- PlayoutEngine reconciles replicas per active output lane; per-route tuner
aggregation keeps lanes from disturbing each other. Recording dispatch gated
to the recording route only.
- PeerDspChain.Clone() gives each output lane independent biquad state.
- ReceiverSelfChecks.FanOutToBothOutputs proves both lanes get audio (self-test).
Offline-marker pile-up fix:
- ResolvePeerDisplayName strips the " (offline)" marker before reuse, so a ghost
peer no longer compounds the suffix hundreds of times in the status line.
Issue #19 (Use-Windows-default follower in the loopback send list):
- DefaultLoopbackSendFollower resolves to the current default render device's
loopback spec, re-applied when the default changes.
Per-application send engine core (issue #20) - WASAPI-only, Win10 19041+ gated:
- CaptureKind.ProcessLoopback + ProcessLoopbackId ("proc:<pid>").
- AudioAppEnumerator: snapshots apps with audio sessions, tracked by process
name, releasing every session object each pass so nothing piles up.
- ProcessLoopbackCapture: IWaveIn over the process-loopback activation API
(hand-rolled COM interop; NAudio has no binding). Fixed 48k/float/stereo.
- CaptureSource IWaveIn overload; MixingEngine opens "proc:<pid>" sources with
no MMDevice and no render keepalive. ASIO path untouched.
- Self-test enumerated real apps on hardware; support gate verified.
UI (Preferences device/app mode + app checklist), ApplySendSources app specs,
and the reconcile timer are still to come. Gate: 15/15.
