Engine died during break-in

Well, that tells you everything if your looking for a fault from a short. Your getting spark at the coil but not at the plugs? Has to be phasing. your not going to see a spark at any plug if the spark is happening between plug contacts. Hard to imagine spark at cap input but nothing at the 8 outputs? They are almost physically bridged by the rotor. Just a small gap.

Details, details.:D
I don't remember ever seeing or hearing that a rotor or button was grounded out except maybe the spark going down through the rotor to ground, so no continuity between the cap coil terminal and ground would be normal wouldn't it? (that answer is yes):D

The fact that there is spark to the cap but not out of it usually means the rotor is either broken, not seated or not turning. (we could call that phasing if you like):D
Phasing would certainly be off if the rotor isn't seated where it belongs.
Phasing being that far off doesn't just happen for no reason so rotor seated and spinning with the motor seems to be the next verification, right?
