feat: add LoRa SDR receiver with Docker runtime infrastructure
...
LoRa receiver flowgraph built programmatically via gr-mcp:
- osmosdr_source → low_pass_filter → lora_rx → message_debug
- XML-RPC server for runtime variable control (samp_rate,
center_freq) with introspection enabled
- Qt frequency sink for spectrum visualization
Docker infrastructure:
- gnuradio-lora: gr-lora_sdr OOT module from EPFL (chirp spread spectrum)
- gnuradio-lora-runtime: combined runtime with Xvfb + gr-lora_sdr
- Compose file, entrypoint, and launch script for LoRa receiver
Also includes:
- lora_scanner.py: multi-SF LoRa scanner example
- lora_infrastructure_test.py: hardware-free pipeline validation
(signal_source → throttle → null_sink + xmlrpc variable control)
- Integration tests for LoRa scanner flowgraph construction
End-to-end pipeline validated: launch_flowgraph → connect_to_container →
list_variables → get/set_variable all working through Docker + XML-RPC.

docker: add audio passthrough for containerized FM receiver
...
New files for running the FM receiver in Docker with audio output:
- Dockerfile.gnuradio-audio: GNU Radio image with ALSA→PulseAudio bridge
- libasound2-plugins for ALSA PulseAudio plugin
- /etc/asound.conf configures ALSA to route to PulseAudio
- docker-compose.fm-receiver.yml: Full FM receiver setup
- PulseAudio socket mount for audio
- USB passthrough for RTL-SDR (requires privileged mode)
- XML-RPC port 8090 exposed for tuning control
- Environment vars: FREQ_MHZ, GAIN
- entrypoint-fm.sh: Builds and runs flowgraph at specified frequency
- run-fm-receiver.sh: Helper script with usage instructions
Usage:
HOST_UID=$(id -u) FREQ_MHZ=107.2 docker compose -f docker/docker-compose.fm-receiver.yml up

runtime: Phase 2 ControlPort/Thrift integration
...
Add ControlPort/Thrift support as an alternative transport to XML-RPC:
New middleware:
- ThriftMiddleware wrapping GNURadioControlPortClient
New MCP tools:
- connect_controlport, disconnect_controlport
- get_knobs (with regex filtering), set_knobs (atomic)
- get_knob_properties (units, min/max, description)
- get_performance_counters (throughput, timing, buffers)
- post_message (PMT injection to block ports)
Docker support:
- enable_controlport param in launch_flowgraph
- ENABLE_CONTROLPORT env in entrypoint.sh
- ControlPort config generation in ~/.gnuradio/config.conf
Models: KnobModel, KnobPropertiesModel, PerfCounterModel,
ThriftConnectionInfoModel, plus ContainerModel updates.

coverage: add cross-process coverage collection for containerized flowgraphs
...
New MCP tools:
- collect_coverage(name) - combine parallel files, return summary
- generate_coverage_report(name, format) - HTML/XML/JSON reports
- combine_coverage(names) - aggregate across test runs
- delete_coverage(name?, older_than_days?) - cleanup
Modified:
- launch_flowgraph() now accepts enable_coverage parameter
- stop() uses 30s timeout for graceful shutdown (coverage needs atexit)
Docker:
- Dockerfile.gnuradio-coverage extends runtime with python3-coverage
- entrypoint-coverage.sh wraps execution with coverage run
- .coveragerc configured for GNU Radio source paths
Tests: 125 unit tests (21 new), 80% coverage

runtime: Phase 1 Docker + XML-RPC control
...
Add RuntimeProvider with 17 MCP tools for controlling running flowgraphs:
- Container lifecycle: launch, list, stop, remove
- Connection: connect by URL or container name
- Variable control: list, get, set via XML-RPC introspection
- Flowgraph execution: start, stop, lock, unlock
- Visual feedback: screenshot capture, container logs
Docker is optional - 10 tools work without it for external flowgraphs.
Includes:
- DockerMiddleware wrapping docker.DockerClient
- XmlRpcMiddleware wrapping xmlrpc.client.ServerProxy
- Dockerfile with Xvfb + ImageMagick + VNC for headless QT
- 29 new unit tests (71 total)
