Sources
Every fact is auditable to where it came from.
Every fact carries provenance. Nothing is asserted without a source, and each answer traces back to the page it came from, when it was fetched, and how strongly the source supports it.
#What a fact carries
Every current fact, as returned by a profile, carries:
| Field | Meaning |
|---|---|
value | The typed value (bool, string, list, or object) |
confidence | 0 to 1, how strongly the source supports the fact |
observedAt | When it was fetched |
stale | Whether it is past its freshness TTL |
Behind each fact is a source record with the exact URL it came from, the time it was fetched, and how strongly that source supports the value.
#Confidence
Confidence reflects how the fact was established, not a vote.
- Deterministic signals are high confidence. A published npm package, a
*-mcpGitHub repo, or a servedllms.txtfile set their facts at 0.9 and above, because the evidence is hard. See Methodology. - Vendor-verified facts are high confidence, after a domain claim.
- A single-source model extraction is medium.
- An inferred value is lower.
#Citations you can check
research_company returns its sources array directly, so you can
open or cite the exact URLs behind the answer. The answer is grounded strictly in those
sources: if a source does not support a claim, the claim is not made.
