feat: add incremental OOT block path management and auto-discovery
...
Add add_block_path() and get_block_paths() MCP tools for incremental
OOT module loading with BlockPathsModel responses. On startup, auto-scan
/usr/local/share and ~/.local/share for OOT blocks so modules like
gr-lora_sdr are available without manual configuration.

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.

feat: add gap analysis tools, OOT block loading, and configurable Docker image
...
Source changes spanning three features:
- Gap analysis: 12 new MCP tools (generate_code, load_flowgraph,
search_blocks, get_block_categories, flowgraph options, embedded
Python blocks, expression evaluation, block bypass, export/import)
- OOT support: load_oot_blocks tool + auto-discovery of paths like
/usr/local/share/gnuradio/grc/blocks for third-party modules
- Docker: configurable image parameter on launch_flowgraph for
running OOT-enabled containers (e.g. gnuradio-lora-runtime)
Resolves merge from feat/oot-block-paths into gap analysis work.
All 274 tests pass (204 unit + 70 integration).

feat: add OOT (Out-of-Tree) block path loading support
...
Add load_oot_blocks MCP tool to dynamically load GNU Radio OOT modules.
Since GRC's Platform.build_library() clears all blocks on every call,
the implementation combines default block paths with OOT paths before
rebuilding. This allows loading custom blocks from:
- /usr/local/share/gnuradio/grc/blocks (locally-built)
- Custom user-specified directories
Implementation:
- PlatformMiddleware.load_oot_paths(): validates paths, combines with
defaults, rebuilds library
- PlatformProvider.load_oot_blocks(): exposes method to MCP layer
- McpPlatformProvider: registers load_oot_blocks tool
Returns useful diagnostics: added_paths, invalid_paths, and block
counts before/after reload.

tests: add integration tests for runtime middleware
...
Add comprehensive integration tests that don't require Docker:
- test_xmlrpc_subprocess.py: Tests XmlRpcMiddleware against a real
subprocess-based XML-RPC server. Covers connection, variable
discovery, get/set operations, and flowgraph control (18 tests).
- test_mcp_runtime.py: Tests MCP runtime tools via FastMCP Client.
Verifies connect, disconnect, list_variables, get_variable,
set_variable, and flowgraph control work end-to-end (15 tests).
- test_fm_scanner.py: Tests signal probe functionality and FM scanner
parsing. Includes unit tests for helper functions and integration
tests for flowgraph construction with signal probe blocks (18 tests).
All 59 integration tests pass. These tests provide faster feedback
than Docker-based tests while still exercising real XML-RPC
communication and flowgraph construction.

fix: remove stale lru_cache from FlowGraphMiddleware.get_block
...
The lru_cache on get_block() caused three cache coherence bugs:
1. Removed blocks remained accessible — set_block_params would
modify a detached block object that no longer exists in the
flowgraph, so save_flowgraph would serialize stale state.
2. Re-created blocks with the same auto-generated name would
return the cached (removed) block instead of the new one.
3. Renamed blocks (via set_block_params id=...) left phantom
cache entries under the old name.
Fix: always look up blocks from the live flowgraph. Block lookup
is a linear scan of typically <20 blocks — no cache needed.
Raises KeyError instead of StopIteration for missing blocks.

runtime: handle GRC servers without XML-RPC introspection
...
GRC's SimpleXMLRPCServer uses register_instance() which doesn't
expose system.listMethods. Wrap the connectivity check in a
try/except so a Fault is treated as "connected" while
ConnectionRefusedError still propagates.

runtime: add dynamic port allocation for Docker containers
...
Prevent silent Docker bind failures by checking port availability
before container creation. Supports auto-allocation (port=0) and
patches compiled flowgraphs when the embedded XML-RPC port differs
from the requested port.

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

tests: add RuntimeProvider coverage (82% → 94%)
...
Unit tests (35):
- Mocked DockerMiddleware and XmlRpcMiddleware
- Full coverage of orchestration logic, preconditions, state tracking
Integration tests (6):
- Real Docker containers with gnuradio-runtime image
- End-to-end: launch → connect → control variables → stop
- Skip gracefully when Docker/image unavailable
Total: 112 tests, 94% 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)
