cx overview/symbols returns "no matches" for some C++ files on Windows, even after cache clean and full reindex

[Occupied-By-Aurora]

Some C++ files in the same repository can generate results normally, while others consistently return no matches.
From the observed behavior, it is more likely that the current C++ extraction logic in cx has incomplete support for certain types of AST structures.
A correlation has been observed so far:
For working samples, most class/member implementations are placed inside namespace blocks.
For failing samples, most class definitions/member implementations are written in the global scope, with member implementations in the form of ClassName::Method(

Can you give me some way to reproduce what you're seeing? a repo to use it on, or just a file to demonstrate. I cannot diagnose correctly without it.

Failing command:

cx overview GuideModule/algorithm/Guide2DLineDemoAlgorithm.h --root

Actual output:

cx: updating 2 files...
cx: no matches
cx: no matches

After the index is already updated, the same file still returns:

cx: no matches

symbols also returns no matches for the same header:

cx symbols --file GuideModule/algorithm/Guide2DLineDemoAlgorithm.h --root

Output:
cx: no matches

However, the corresponding .cpp file in the same directory is indexed correctly:

cx overview GuideModule/algorithm/Guide2DLineDemoAlgorithm.cpp --root

Output:

[7]{name,kind,signature}:
AlgorithmId,method,"QString Guide2DLineDemoAlgorithm::AlgorithmId() const"
AlgorithmParams,fn,QVariantMap AlgorithmParams(const GuideAlgorithmDataView& ctx)
Execute,method,"GuideRuntimeResult Guide2DLineDemoAlgorithm::Execute(const GuideAlgorithmDataView& ctx)"
LineAlgorithmId,fn,QString LineAlgorithmId()
Preview,method,"GuidePreviewResult Guide2DLineDemoAlgorithm::Preview(const GuideAlgorithmDataView& ctx)"
ShiftLineNodeGeometry,fn,"GuideLineNodeGeometry ShiftLineNodeGeometry(...)"
Validate,method,"bool Guide2DLineDemoAlgorithm::Validate(const GuideAlgorithmDataView& ctx, QString& errorMsg) const"

The failing header is a declaration-only C++ header using #pragma once, UTF-8 with BOM, and a global-scope class declaration.

So the current narrowed-down observation is:

• .cpp definitions are detected correctly.
• declaration-only .h files with class declarations return no matches.
• This is reproducible with at least Guide2DLineDemoAlgorithm.h and Guide2DPointDemoAlgorithm.h in the same project.

This should be fixed with the latest release, please update and try again.
