# What counts as a verified fact?

> A fact an AI agent can trust because it traces back to a real source, a business's own booking system, a supplier feed, a confirmed document, rather than to unverified marketing copy or a crawled page.

## In short

- A verified fact traces to a real source, a booking system, a supplier feed, not just to marketing copy.
- An agent weighs a fact differently depending on where it came from, whether a business accounts for that or not.

Good for: Deciding how much weight to give a specific claim. Not good for: A strict yes or no test. Trust is graded by source, not binary.

Not every true statement counts the same. A claim taken from a business's own live PMS or stock system carries more weight than the same claim taken from a paragraph on a website, because the first one is checkable against a system of record and the second is just prose someone wrote. An agent deciding whether to recommend or book something weighs facts this way whether or not a business realises it's happening, which is why where a fact comes from matters as much as whether it's true.

## Good for

Deciding how much weight to give a specific claim.

## Not good for

A strict yes or no test. Trust is graded by source, not binary.
