* need the keys.
*
* Slice 5: returns Role[] (the union) rather than PlatformRole[]. The
* keys can be either platform or customer roles depending on what the
* project authorization granted; the SessionUser carries them all and
* downstream helpers (canMutate, isCustomerOwner, requirePlatformRole)
* decide what each subset means.
