Finding (Critical, open): multi-story layouts stack wall levels with no floor cassette/rim geometry between stories.
Acceptance: L2 walls sit on a modeled floor system (even a first-pass rim+cassette placeholder with real thickness); story heights correct in .FCStd (both compilers) and fab outputs; parity + CI green. Blocks Phase 2 multi-story.
