The crawler records currently include administrator-reported aggregates and are marked as discovery evidence, not citation proof.

P0-P6 evidence ladder

1. P0 Published: A stable URL answers with a content type, a timestamp and a hash.
2. P1 Accessible: External HTTP access without authentication and without client-side rendering.
3. P2 Crawled: A crawler requested a specific resource, and the request was checked against the provider's published ranges or reverse DNS.
4. P3 Retrieved: A resource fetch is traceable to a user-triggered query.
5. P4 Cited: An observed AI answer contains the URL.
6. P5 Fact matched: An answer reproduces a versioned, source-backed value from the record.
7. P6 Answer influenced: A controlled experiment with one changed factor supports causal influence.

What a level does not mean

• A higher level is never inferred from a lower one.
• A crawler visit is not retrieval; retrieval is not citation; a citation is not use of a fact.
• A user agent string is a claim, not an identity: an unverified request is recorded as unverified, never as a provider visit.
• An observation without the provider, the exact model name and the date is not evidence and is not stored as one.
• No level, alone or combined, supports a statement about a lost sale, a ranking or revenue.
