…xtension) Implements the full plugin extension system allowing third-party packages to contribute CLI commands and MCP tools to CGC via Python entry points. Core infrastructure: - PluginRegistry: discovers cgc_cli_plugins/cgc_mcp_plugins entry-point groups, validates PLUGIN_METADATA, enforces version constraints, isolates broken plugins - CLI integration: plugin commands attached to Typer app at import time; `cgc plugin list` - MCP server integration: plugin tools merged into tools dict; handlers routed at call time Plugins implemented: - cgc-plugin-stub: minimal reference fixture for testing and authoring examples - cgc-plugin-otel: gRPC OTLP receiver, Neo4j writer (Service/Trace/Span nodes, CORRELATES_TO links to static Method nodes), MCP query tools - cgc-plugin-xdebug: DBGp TCP listener, call-stack parser, dedup writer (StackFrame nodes, CALLED_BY chains, RESOLVES_TO Method links), dev-only - cgc-plugin-memory: MCP knowledge store (Memory/Observation nodes, DESCRIBES edges to Class/Method, FULLTEXT search, undocumented code queries) CI/CD and deployment: - GitHub Actions: plugin-publish.yml (matrix build/smoke-test/push via services.json), test-plugins.yml (PR plugin unit+integration tests) - Docker: docker-compose.plugin-stack.yml (self-contained full stack with Neo4j healthcheck + init.cypher), plugin/dev overlays, all plugin Dockerfiles - Kubernetes: otel-processor and memory plugin Deployment+Service manifests - Fixed docker-compose.template.yml: neo4j healthcheck was missing (broke all overlay depends_on: service_healthy conditions), init.cypher now mounted Tests (74 passing, 17 skipped pending plugin installs): - Unit: PluginRegistry, OTEL span processor, Xdebug DBGp parser - Integration: OTEL neo4j_writer, memory MCP handlers, plugin load isolation - E2E: full plugin lifecycle, broken plugin isolation, MCP server routing Documentation: - docs/plugins/authoring-guide.md: step-by-step plugin authoring with examples - docs/plugins/cross-layer-queries.md: 5 canonical cross-layer Cypher queries (SC-005) - docs/plugins/manual-testing.md: Docker and Python testing paths, per-plugin verification sequences, troubleshooting table - docs/plugins/examples/send_test_span.py: synthetic OTLP span sender for OTEL testing - .env.example: documented all plugin environment variables - CLAUDE.md: updated with plugin directories, entry-point groups, test commands Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
CI/CD workflow fixes:
- e2e-tests.yml: add FalkorDB service container with health check, bump
checkout@v3->v4 and setup-python@v4->v5, add cache: pip, expose
FALKORDB_HOST/FALKORDB_PORT/DATABASE_TYPE env vars for test runner
- macos.yml: replace || true shell suppression with continue-on-error: true
on Install system deps, Run index, and Try find steps
- test-plugins.yml: remove silent pip fallback from core install step so
broken installs fail fast instead of silently proceeding with partial deps
- test.yml: add cache: pip to setup-python step
Application fixes (from python-pro):
- cgc.spec: PyInstaller frozen binary fixes
- tests/integration/plugin/test_otel_integration.py: asyncio fix
- tests/integration/plugin/test_memory_integration.py: importorskip guards
- tests/unit/plugin/test_otel_processor.py: importorskip guards
- tests/unit/plugin/test_xdebug_parser.py: importorskip guards
- plugins/cgc-plugin-{stub,otel,xdebug,memory}/README.md: plugin READMEs
- pyinstaller_hooks/: PyInstaller runtime hooks for plugin discovery

…39+ compatibility falkordblite requires glibc 2.39+, which is not available in the manylinux2014_x86_64 image (glibc 2.17). Switch the Linux PyInstaller docker build to quay.io/pypa/manylinux_2_39_x86_64. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…s to __init__.py All four plugin pyproject.toml files declared entry points with a module:attribute suffix (e.g. cgc_plugin_stub.cli:get_plugin_commands), causing ep.load() to return a function rather than the module. The PluginRegistry calls ep.load() and reads PLUGIN_METADATA, get_plugin_commands, get_mcp_tools, and get_mcp_handlers off the returned object as module attributes — so loading always failed. Fix: remove the colon-attribute suffix so each entry point resolves to the package module (e.g. cgc_plugin_stub). Add re-exports of get_plugin_commands, get_mcp_tools, and get_mcp_handlers from the cli/mcp_tools submodules into each plugin's __init__.py so the registry finds them on the loaded module.

…r Linux frozen binary
The Linux manylinux_2_39_x86_64 falkordblite wheel (produced by auditwheel)
installs vendored shared libraries into a `falkordblite.libs/` directory
(libcrypto, libssl, libgomp) that is not a Python package. collect_all() and
collect_dynamic_libs() only walk the importable top-level packages listed in
top_level.txt ('dummy', 'redislite') and therefore silently miss falkordblite.libs/,
causing runtime linker failures inside the PyInstaller one-file executable.
Changes:
- Add explicit search_paths scan for falkordblite.libs/*.so* and register each
file as a binary with destination 'falkordblite.libs'
- Collect dummy.cpython-*.so (auditwheel sentinel extension) from site-packages
roots and register it at the bundle root
- Add 'dummy' to hidden_imports (non-Windows) to cover the importable top-level
package declared in falkordblite's top_level.txt
pyproject.toml dependency marker (sys_platform != 'win32' and python_version >= '3.12')
is correct — no change needed there.
