Note that my body also protected the bike, which suffered only a slight scuff of the bar tape in the incident!

In this type of situation, your head will smack the ground without you even knowing, because it recoils so fast.
I'm willing to bet the helmet absorbed some of it, even without showing much.
I had a similar situation and there was no damage at all shown on the outside but with close inspection, a tiny hairline crack in the foam.
That absorbed what could have been the back of my head.
So, it could be fine but I would (as the other person said) relegate it to backup duty.
Really inspect it too. Is it *slightly* non-symetrical from the top, side, front/back?
If there is even a tiny crack in the foam, realize the absorbing capability is compromised.
Don't be shy about tossing helmets. Mine was a $200 Giro but when you consider the alternatives, it's really nothing.
Besides, so many cool under $100 helmets nowadays...
Incidentally, I look for helmets with a lower rear section to protect the lower sides of the skull more.
Some are better than others with road helmets.
