- Sort gate candidates by destination-side before tier, so an on-ray point behind the center loses to any destination-side aimed/scan point
- Add a new soft "facing from the center" check in tests: when some anchor's tether circle reaches the destination side (maxProj + tether > 0), the gate must lie there; a single far planet may still take the best aimed point
- Prefer a destination-side aimed candidate in the clearance fallback
