* feat(cpp): add standard-conversion-sequence ranking to overload resolution (#1578) Introduce `ConversionRankFn` abstraction and `cppConversionRank` implementation to disambiguate C++ overloaded calls by argument-to-parameter conversion cost. Exact type match (rank 0) beats standard arithmetic conversion (rank 2), which beats non-viable mismatch (Infinity). Thread the rank function through `narrowOverloadCandidates`, `pickImplicitThisOverload`, `pickOverload`, and `pickUniqueGlobalCallable` via the `ScopeResolver.conversionRankFn` contract. Add `findAllCallableBindingsInScope` scope walker for collecting all overloads at the first binding scope. Guard against false ambiguity suppression when candidates span different files (local-shadows-import preservation). * fix: address Claude review findings on conversion-rank PR Finding 1 (HIGH): add tests that exercise the conversion ranker. - p('a') with p(int)/p(double): char→int promotion (rank 1) beats char→double conversion (rank 2), forcing step 4b in narrowOverloadCandidates. Exact-type filter misses both overloads. - h(42, 2.5) with h(int,int)/h(double,double): multi-arg tied total score forces the ranker, both candidates score 2 → suppressed. Finding 2 (HIGH): unify multi-candidate suppression across all paths. - Non-ADL free-call: suppress when narrowed.length > 1 (same-file guard), mirroring ADL merged-candidate behavior. - ADL ordinary-only: same pattern. - pickOverload: return OVERLOAD_AMBIGUOUS when candidates.length > 1 after normalized-ambiguity check. - Case 0.5 (this receiver): set ambiguous=true when narrowed > 1. Finding 3+4 (MEDIUM): implement rank-1 integral promotions. - char→int and bool→int now return rank 1 (ISO C++ [conv.prom]). - Updated comment to remove misleading ISO table header; document only the post-normalization ranking that is actually implemented. - Updated ConversionRankFn JSDoc in overload-narrowing.ts. 218/218 C++ tests pass (registry-primary). Legacy: 186+32. * fix: implement pairwise dominance comparison for overload ranking Replace the summed per-slot conversion cost with ISO C++-aligned pairwise dominance comparison ([over.ics.rank]). F1 is better than F2 only when F1 is not worse for every argument and strictly better for at least one. Non-dominated candidates are returned; if multiple remain they are genuinely ambiguous. This fixes false CALLS edges for asymmetric multi-arg overloads: h('a', 2.5) against h(int,int) / h(double,double) — the old summed cost picked h(double,double) (cost 2 < 3), but ISO C++ considers the call ambiguous because h(int,int) is better at arg 0 via char promotion. The pairwise check correctly finds neither dominates. Add h('a', 2.5) test case asserting zero CALLS edges alongside the existing h(42, 2.5) symmetric-tie test. 218/218 C++ tests pass (registry-primary). Legacy: 186+32. * docs: update step 4b JSDoc to reflect pairwise dominance --------- Co-authored-by: Gergő Magyar <gergomagyar@icloud.com> |
