op25-container/system.pa New PulseAudio config: auth-anonymous=1 so the edge-node can connect without group membership
op25-container/Dockerfile Copies system.pa into /etc/pulse/system.pa
drb-edge-node/Dockerfile Added libpulse0 — ffmpeg needs this runtime library to use -f pulse
drb-edge-node/app/internal/call_recorder.py Switched recording from Icecast (burst-buffer overlap) to PulseAudio monitor (zero-delay, exact call boundaries)
