Squashed buildout of the tgcalls testbench: - CLI test tool with --mode p2p/reflector/group/group-churn, cross-version interop (--version, --version2), and quiet/summary output - Linux toolchain + Docker multi-stage build, AWS Fargate mass test harness, local parallel mass test harness with signaling loss simulation - SCTP writable gate, retransmission timer tuning, role-based handshake - InstanceV2CompatImpl (PeerConnection backend with V2Impl signaling) and SignalingTranslator for v14.0.0 interop - In-process Go/Pion SFU (ICE+DTLS+SRTP+SCTP per participant) with audio RTP forwarding, ActiveAudio/VideoSsrcs data channel broadcast, RTCP feedback path, and CGo c-archive integration - GroupInstanceReferenceImpl (PeerConnection group-call) and mixed-impl group mode (--reference-participants), with SDP munging for simulcast - H264 simulcast group video (FakeVideoTrackSource pattern generator, FakeVideoSink frame counting, --video flag, two-pass channel setup, reactive video setup from ActiveVideoSsrcs) - Group churn stress mode (--mode group-churn, --churn-cycles) - SFU stream-quality adaptation: BandwidthEstimator, LayerSelector state machine, RtxRingBuffer, simulcast SSRC rewrite - Transport-cc feedback generation, NetworkSimulator (delay/jitter/loss/ token-bucket bandwidth), --network-scenario step-down-up - CLAUDE.md updates throughout Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
