I was more trying to suggest you should follow line 35 and assign to a local
variable - and assert that local variable is fine.

This pattern is dangerous because there is zero relationship with the subsequent
lines - that is, if you changed line 47 to kCertFilename3, it would have no
effect on these.

Assigning to a local variable, asserting that variable is valid, and then
pushing it to the object gives you the desired guarantee.

Done.
