Base-type matching and type-parameter-constraint matching implement the same inference steps through separate representations and predicates. This refactor shares those steps without adding tagged wrapper dispatch.
Introduce
MatchingPositionfor argument positions and constrained type arguments. Each position supplies its declared and inferred types, target, and candidate-selection rules. Both cases then use the same relevant-access representation, constraint matching, andbaseTypeMatchpath projection. Existing base-type candidate filtering and type-parameter-only disambiguation are preserved.Validation:
codeql test run --additional-packs=. unified/ql/test/library-tests/type-inferencepasses with unchanged expected results.
