# Multi-file regression

Human review: pending. Expected output was independently traced by AI.

These are compiler extensions, not Cambridge guide requirements. Add returns 3. Globals start at 3/shared/TRUE/Q/-1.5. Increment adds the library constant 2. Shadow prints its local 40 without changing the global 5. The entry local 99 survives another library increment; ReadCounter returns the shared 7. Functions precede GLOBAL declarations to check pre-pass visibility.
