You may have authenticated access to the creator of the object that you wonder about. The alleged type clue may send you to the correct creator which is not itself a type. If object O says it is a “Fresh segment”, O(kt) => 0x50F, then you can consult the public key FSC, sending it O and it will say yes or no. (It seems the manual does not give that order on FSC. That may be an oversight or we may indeed not have added that code while we still had access to the Augment system.) The standardized creator, the factory, does provide this service. Under broad circumstances an authoritative answer can be had via the brand which ultimately uses the domain tool logic in the kernel.
