Fixes #852.

Introduce the public resource plugin API and direct registration macro, load configured resource plugins before modules and sources, and add an end-to-end fixture covering unlimited and serialized resource injection.

  • Code

    • Add the public PHLEX_REGISTER_RESOURCES API in phlex/resource.hpp.
    • Support unlimited and serialized resource registration through resources_graph_proxy.
    • Add load_resources and load resource plugins before modules, sources, and drivers.
    • Replace source_bundle with the shared graph_registration_bundle.
    • Preserve resource catalogs and registration errors across plugin entry points.
  • Build system

    • Add the exported phlex_resource interface library.
    • Install phlex/resource.hpp.
  • Tests

    • Add resource plugin fixtures for configuration-driven resource construction.
    • Verify unlimited and serialized resource injection.
    • Add the job:resources integration test.

Introduce the public resource plugin API and direct registration macro,
load configured resource plugins before modules and sources, and add an
end-to-end fixture covering unlimited and serialized resource injection.

Layer / File(s) Summary
Registration contracts and shared bundle
phlex/core/graph_proxy.hpp, phlex/resource.hpp, phlex/core/framework_graph.hpp, phlex/source.hpp, phlex/detail/plugin_macros.hpp
Adds graph_registration_bundle, resource registration methods, PHLEX_REGISTER_RESOURCES, and updated source plugin callback types.
Resource plugin loading and execution
phlex/app/load_module.cpp, phlex/app/load_module.hpp, phlex/app/run.cpp
Loads configured resource plugins, retains their libraries, invokes create_resources, and processes resources before other plugin categories.
Build integration and resource workflow test
phlex/CMakeLists.txt, test/plugins/CMakeLists.txt, test/plugins/resources.*, test/plugins/resources_module.cpp, test/plugins/resources.jsonnet
Installs and builds the resource API, adds resource test plugins, and verifies configured and serialized resources in a workflow test.

Full details: Linked Issues check

Explanation

The implementation satisfies the main [#852] objectives. PHLEX_REGISTER_RESOURCES defines the plugin ABI. load_resources retains the shared library and invokes the creator. run loads resources before modules and sources. resources.jsonnet supplies plugin configuration, and resources_module.cpp declares resource dependencies. The added job:resources test covers configured construction, serialized and unlimited resources, and dependency use. The changed test set does not provide integration coverage for resource-plugin registration errors or malformed resource configuration, which [#852] explicitly requires. The existing registration-error plumbing is reused, but the required automated error-handling coverage is not demonstrated.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 18 functions across 11 files. (3 skipped: 3 unsupported.)

- Around line 14-16: Replace the `assert` checks in the resource-injection
workflow with an always-active failure path so validation remains enforced under
`NDEBUG`; update the relevant include and make the test abort when `configured`
is null, its value is not 42, or `serialized` is null.

10-14: 🎯 Functional Correctness

The missing-header claim is refuted. phlex::module and phlex::resource are managed by cet_make_library, which supplies ${PROJECT_SOURCE_DIR} as a build-interface include path. Their usage requirements propagate through the PRIVATE links in test/plugins/CMakeLists.txt:10-14. No local include-directory change is required.
