update
as of today (1 week post-flight), no miles posted at all.
so I called WP line and they said they had received the boarding pass and emailed receipt/itinerary, but needed the CO ticket number.
I called back a few hours later with the ticket number. this agent says 1. she doesn't need or want the e-ticket number because 2. there is "no place to put it" and 3. i'll just have to wait 4-6 weeks for the miles to post becuase they are entered by hand.
That wasn't the answer I was looking for, so I called back a third time. He takes my e-ticket number, calls his supervisor, enters it in the system, and says they should be "swept" by the computer this evening.
4 hours later, miles have posted to the account... with 50% EQM bonus, to boot, as slippahs hinted. coincidence? who knows? but all is happily, and quickly, resolved.
