Important documents should be able to show their work.

These descriptions explain the idea, not a promise that every document or reader implements every capability.

Universal Document

A document that can explain where its important information came from, what changed, what is missing, and what happened to it.

Provenance

Where did this come from?

Provenance product

A way to show exactly what evidence supports an important claim.

UD provenance

UD helps important claims show their receipts.

Verify

Check whether the evidence still matches the exact document state.

UNKNOWN

The available evidence does not support an answer.

Conflict

Relevant sources disagree; neither is silently discarded.

Manifest

An inventory used to check whether protected files changed.

Internal “friction wedge” means starting with one expensive, annoying problem instead of trying to solve everything at once. It is not a customer-facing product tier.
