Baseline verification
The implementation smoke is verify_baseline.ps1. It is not a parser corpus.
From the project root, in a fresh PowerShell process:
.\scripts\verify_baseline.ps1 -Mode positive -MirrorRoot ..\gencpp-verify-positive
.\scripts\verify_baseline.ps1 -Mode positive -MirrorRoot ..\gencpp-verify-positive -ReuseMirror
The first command generates base component tables, segmented C++, single-header C++, and both C11 layouts. It compiles and runs the C++17 and C11 single-header host smokes. The second command reuses the same mirror.
The verification wrapper copies them into the disposable mirror; it does not embed C or C++ source text.
