Detailed Description
Marks a function parameter as an output container (e.g.
std::vector<T>& that the function fills). Constructed via the INTEROP_OUT(var) macro.
Purpose:
- Excluded from the reproducer's argument list (it's an output, not input).
- If the container holds pointers, its elements are registered as handles at trace-region exit so later calls can reference them by name.
The container type is erased at construction via MakeOutParam() so that all downstream code (ReproBuffer, TraceRegion) works with a single concrete type — no template specializations or detection traits needed.

◆ IsPointerContainer
| bool CppInterOp::Tracing::OutParam::IsPointerContainer = false |
Drives the _outN preamble + alias path.
Non-pointer containers stay on the legacy "skip in arg list" rendering – their type is not erasable to void*, so the preamble decl would not type-check.

◆ IsScalarPointer
| bool CppInterOp::Tracing::OutParam::IsScalarPointer = false |
Scalar pointer OUT (e.g. bool*); rendered as nullptr.

◆ RegisterHandles
| std::function<void(TraceInfo&, unsigned OutIdx)> CppInterOp::Tracing::OutParam::RegisterHandles |
Register the container's pointer elements as handles and emit one void* vN = _outN[i] : nullptr; decl per newly-registered element so a later call referencing the registered name finds a real binding.

◆ SourceAddr
| const void* CppInterOp::Tracing::OutParam::SourceAddr = nullptr |
Address of the source container object (not its data buffer); multiple calls with the same container alias the same _outN buffer in the reproducer so accumulation across calls replays faithfully.
Stable across capacity growth – a push_back that reallocates the heap buffer leaves the object's address put.
