Narrative Permanence
The capacity of an object to maintain a coherent, verifiable account of its own existence across time. An object with Narrative Permanence cannot be separated from its story without becoming a different object.
Narrative Permanence is what distinguishes a documented object from an undocumented one. The silk carré with provenance, ceremony record, and custodial contract is not the same object as an identical silk carré without documentation, even if their material composition is identical. The narrative is structural. Remove it and you remove something the object needed to be what it was.
Permanence here means survival of transfer, not merely existence. A story its current holder happens to know is not permanent; it is a memory, and memory does not survive an estate. The test is whether the account passes intact to someone who never met the previous custodian and was not present for anything it records.
That makes the record an object of custody in its own right. It can be lost while the thing it describes is perfectly preserved, and when it is, the loss is unrecoverable in a way physical damage often is not. A repaired object is an object with a repair in its history. An object whose history has been forgotten is an object that now has none.
It is also what makes succession a question the framework has to answer rather than defer. An object that cannot be separated from its story has a problem the moment its custodian dies, because that is the point at which the story is most likely to stop travelling. Narrative Permanence is the property that makes the transfer worth designing.
