No, crank is wired correctly.

That scope is fine.
What is probably happening is that the coils are feeding back in to the crank sensor.
Make sure you are using shielded cable for the crank, the shield is properly drained at the ECU end, and the stud on the case is earthed correctly.

No, crank is wired correctly.

Only suggested as trace looked like the dodgy example in the manual!

The only relevant bit in the dodgy trace is the long yellow line directly after the long coloured line.
In the above trace, there is no extra long yellow line, so the crank sensor is wired correctly.
