Resolves #971

  • Code: Replaced hash-based duplicate tracking in find_producers with ordered sets of suffixes, creators, and types. Duplicate values now follow identifier equality rather than hash equality.
  • Code: Updated ambiguity checks and diagnostic logging to use the sets directly. Producer matching and ambiguity outcomes remain unchanged.
  • Tests: No test changes are shown in the supplied diff. Test results are unavailable.

📝 Walkthrough

The producer catalog replaces hash-based duplicate tracking for selector-disambiguation values with ordered sets. Ambiguity diagnostics now format set values directly. Candidate matching and ambiguity outcomes remain unchanged.

Changes: Producer catalog tracking

Layer / File(s) Summary
Track selector values with sets
phlex/core/producer_catalog.cpp
find_producers collects suffixes, creators, and types in ordered sets instead of hash-keyed pointer maps. check_postconditions accepts those sets and formats their values directly. The hash-collision error and related tracking code are removed.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Refactor

Merge Risk: 🔵 Low · up to 8c94a

The change replaces hash-based tracking with sets and keeps selection behavior. Adding the direct set include is a small follow-up, and merge risk is low.

Explanation

Issue #971 requires std::set&lt;identifier&gt; tracking, preserved identifier-based selection behavior, and relevant automated tests. phlex/core/producer_catalog.cpp now uses ordered sets and keeps the existing candidate matching and ambiguity flow. The reviewed change summary lists no test-file changes. The existing test/producer_catalog_test.cpp checks registration and single matches, but it does not test duplicate equality or distinct identifiers that must remain distinct. The test acceptance criterion is therefore unmet.

174-179: 🎯 Functional Correctness

The concern is refuted. phlex/model/type_id.hpp:83 defines constexpr std::strong_ordering operator<=>(type_id const& rhs) const, which provides the ordering required by std::set<experimental::type_id>.

Guard type comparisons in product_selector::match and producer_matches with valid() so an unset query type acts as a wildcard. Add a producer_catalog_test check covering ambiguous untyped queries across products of different types.
