  "summary": "This pull request implements an `IsSymlink` helper in `fs_helpers` that checks for Windows reparse points using `GetFileAttributesW`, working around GCC MinGW's lack of Windows symlink support in `std::filesystem`. It integrates this check into the wallet's `ListDatabases` to prevent recursive scanning of symlinks and into `GetWalletPath` to validate paths properly on Windows, while enabling symlink functional tests for Windows.",
  "problem": "GCC libstdc++ does not detect symlinks on Windows, treating them as regular files or failing to report them. As a result, Windows wallet directory scanning can recurse into symlinked or reparse directories, and path validation fails to catch invalid symlink targets.",
