Thanks, I did see in the FAQs that when Choice members gift points to another member, that the activity is considered non-qualifying for the member who gifts points but qualifying for the member who receives points. This seems consistent with your understanding that any activity that adds points to an account counts as qualifying. Oddly, the FAQ about what is qualifying specifically notes that credit card points and purchasing points are qualifying, but doesn't mention any other partner activities.

Edited to add: I checked the "Program Information" section and it has the broader interpretation of qualifying activities including all partners "Qualifying Activities include completing a qualified point-eligible stay, redeeming Choice Privileges points, earning Choice Privileges points from a purchase from using your Choice Privileges® Mastercard® card, earning points with one of our partner programs, purchasing Choice Privileges points, or referring a friend."
