_{Stack created with GitHub Stacks CLI • Give Feedback 💬}

• Code: Moved registration, product lookup, resource catalog, source, and type-ID implementations out of headers and into compiled source files.
• Code: Added shared join_support for join repeaters and index ports. Join nodes now cache input receivers for runtime lookup.
• Code: Canonicalized delegated algorithm types and updated fold, observer, predicate, and transform nodes to use algorithm_type.
• Build system: Added the new implementation files and installed join_support.hpp.
• Tests: Added coverage for registrar moves and failures, resource registration, join receiver mapping, and algorithm type canonicalization.

📝 Walkthrough

Walkthrough

The changes update join-node wiring, algorithm type handling, registrar and product lookup implementations, resource catalog operations, model type metadata, and Python stringification. Several implementations move from headers to compiled source files.

Changes

Join wiring

Layer / File(s)	Summary
Shared join support phlex/core/detail/join_support.hpp, phlex/core/detail/join_support.cpp, phlex/core/CMakeLists.txt	Adds shared support for repeater creation and index-port management. The core build compiles the implementation and installs the header.
Join-node wiring and receiver lookup phlex/core/fold_join_node.hpp, phlex/core/multilayer_join_node.hpp, phlex/core/message.hpp, phlex/core/message.cpp	Join nodes use shared support, cache data receivers, and resolve receiver indices at runtime. message adds a bounds-checked receiver lookup.
Join behavior tests test/multilayer_join_test.cpp	Tests receiver lookup, index-port identity, same-layer joins, single-input joins, and fold-join selector mapping.

Algorithm type canonicalization

Layer / File(s)	Summary
Delegated algorithm type phlex/metaprogramming/delegate.hpp, phlex/core/fold_node.hpp, phlex/core/observer_node.hpp, phlex/core/predicate_node.hpp, phlex/core/transform_node.hpp, test/transform_node_test.cpp	algorithm_bits now uses one template parameter for the delegated algorithm type. Node aliases and tests use that type.

Node and source registration

Layer / File(s)	Summary
Registrar lifecycle and node creation phlex/core/registrar.hpp, phlex/core/registrar.cpp, phlex/core/fwd.hpp, test/core_misc_test.cpp	Registrar methods move to compiled implementations. The registrar handles moves, creator state, node creation, and duplicate names. Tests cover creator exceptions and moves.
Source registration and default indices phlex/core/glue.hpp, phlex/core/glue.cpp, phlex/core/source.hpp, phlex/core/source.cpp, phlex/core/CMakeLists.txt	glue::add_source delegates insertion and duplicate-name reporting to a helper. The default source::indices() implementation completes without yielding values.

Product selector lookup

Layer / File(s)	Summary
Selector name conversions phlex/core/product_selector.hpp, phlex/core/product_selector.cpp	creator_name and layer_name become exported classes with out-of-line constructors and conversions. Their implementations validate empty identifiers and define absent-name conversions.
Product specification resolution phlex/core/input_arguments.hpp, phlex/core/input_arguments.cpp	retriever::retrieve delegates matching and error reporting to resolve_product, which returns the sole matching specification or reports zero or multiple matches.

Resource catalog

Layer / File(s)	Summary
Resource registration and lookup phlex/core/resource/catalog.hpp, phlex/core/resource/catalog.cpp, test/resources_test.cpp	Catalog registration delegates duplicate checks and insertion to implementation methods. Typed lookup uses a type-indexed helper. Tests cover duplicate unlimited and serialized registrations.

Model product and type metadata

Layer / File(s)	Summary
Product storage insertion phlex/model/products.hpp, phlex/model/products.cpp	products::add delegates storage to a helper that appends the specification and moves the product pointer.
Type ID functions and formatting phlex/model/type_id.hpp, phlex/model/type_id.cpp, phlex/model/CMakeLists.txt	type_id exact-name, hash, and formatting functions move to compiled implementations. The model build includes the new source file.

Python stringification

Layer / File(s)	Summary
Const vector stringification plugins/python/src/modulewrap.cpp	The stringification overloads accept const vectors. Product-selector formatting uses std::views::transform.

Priority: ⚪ Not assessed

Estimated code review effort: 4 (Complex) | ~45 minutes

Change: Refactor

Merge Risk: ⚪ Minimal · up to a90ef

This refactor moves implementations out of line and canonicalizes types, with no behavior change expected. No merge-blocking risk was identified. The review did not build the code.
