BTW, why do you use the resolved URL key here?  What's the difference between
this and the scanned URL key?  I searched the code base and cannot find an
explanation anyway.  (Please consider adding one somewhere if there isn't one.) 
The only thing I found is an example that indicates the resolved one is a "long"
url and the scanned one is "short".

The scanned URL is the URL broadcast by the Physical Web beacon. Due to BLE
packet size limitations, the number of bytes available for the URL is very
constrained, so most Physical Web beacons broadcast a shortened URL. Instead of
displaying this shortened URL, the Physical Web service follows the redirect
chain and returns the final, resolved URL.

We actually have a CL up already that improves the documentation in
physical_web_data_source.h:

Nice!
