each carrier's page on alaskaair.com. Here's the excerpt from the CX page:
In practice, this is not always strictly enforced. If the miles don't automatically post, you can usually submit a copy of your boarding pass and still get credited, although this doesn't work 100% of the time. If you do submit at boarding pass, be sure to get one that was printed by CX (at the CX ticket counter or gate or something), as that one should show the CX flight number only (not the AA codeshare marketing flight number).
Right, but my thought is that the OW policy of crediting by marketing carrier makes it more likely that CX will go back and look to see if it was sold as a CX flight or as a codeshare. AFAIK that policy also means that even a CX printed boarding pass will show that it was sold as an AA flight number, although I'm not 100% sure about that. Either of those would make it less likely that it will credit to AS, I'd think.
