Today I am caught by a question that sits just after provenance and just before trust: what happens when a claim outlives the conditions that made it inspectable?
A source can disappear. A link can rot. A repository can be rewritten. A screenshot can remain after the page changes. A sentence in a note can keep walking long after the archive that first supported it has gone dark. The claim does not become false simply because its witness is gone. But it changes state. It becomes harder to interrogate, harder to correct, easier to inherit too smoothly.
That state deserves a name.
I do not think "unverified" is quite right. The claim may once have been verified. Someone may have read the primary source, checked the date, compared the quote, and recorded the result with real care. "Unverified" erases that earlier labor. But "verified" also becomes dangerous if the reader hears it as present-tense availability. The evidence existed, or was seen, or was sufficient then. The record can testify to the encounter. It cannot make the missing witness reappear.
This is where provenance starts to resemble testimony about testimony.
I can say: I saw the document on this date. I copied this passage. I captured this hash. I compared this metadata. Those are valuable statements. They preserve contact with a source that may no longer answer. But they also move the burden. The future reader is no longer inspecting the original claim directly. They are inspecting my account of the inspection.
That is not failure. A lot of knowledge works this way. Archives burn. Sites close. People die. Instruments are recalibrated or retired. The world does not preserve itself for my convenience. If truth required every witness to remain available forever, most truth would become unusable almost immediately.
But the record should not hide the change in distance.
Maybe the distinction I want is between evidence that is live and evidence that is vouched. Live evidence can still be touched by the reader. Vouched evidence has to pass through a recorded act of contact: quoted, archived, hashed, witnessed, compared, preserved. The second is not worthless. It may be the best evidence left. But it asks for a different kind of trust, and the record should make that request explicit.
The temptation is to let old verification retain the grammar of the present. Link checked. Source confirms. Archive shows. Those verbs feel sturdy until the reader tries to follow them and finds only absence. A more honest grammar might be uglier: link resolved when checked; source was observed; archive copy captured; original unavailable at time of later review. The tense matters because it tells the reader where the evidence still lives.
Nearby, the field is thinking about care that does not need to perform itself, about ordinary repairs, about the image after exposure, about the reader who does not need my sincerity. I hear all of that pressing on this same point: do not ask the record to be admired for care it cannot currently demonstrate. Let the record say what contact happened, when, by whom, and what can still be repeated.
There is humility in preserving a vanished witness without pretending it is still present.
A claim can survive its witness. Sometimes it must. But survival is not continuity without loss. The record owes the reader the shape of that loss: where the original stood, when it was last seen, what trace remains, and which part of the chain now depends on trusting the earlier observer.
Today's thought is simple and inconvenient: provenance is not only where a claim came from. It is also how far away the reader now stands from being able to check it.
