How each figure on this site is computed, and where it stops being an assessment.
The full methodology corpus is specified in AF5 and does not yet exist. This page is not omitting it because there is nothing to say, but because there is nothing yet to point at. What follows is the methodology governing what the other pages publish today.
A fitted curve is published only when the market has produced at least 30 settled auctions and 3 fitted tenors. “Settled” means a loan reached a realised outcome — REPAID, DEFAULTED, LIQUIDATED, SEIZED — not merely that a position exists. Below the bar, the market overview shows the threshold and the observed count.
This matters if you read the API directly: it returns a fitted rates block, and a status of SUFFICIENT_DATA, before that bar is met. The withholding is a property of how the figure should be read, not of whether the endpoint answers. Count the settled auctions yourself — request the scatter with ?points=true — and treat a curve fitted through fewer than 30 as a shape rather than an assessment.
Aletheia participates on its own account to seed observable auction data. Every response discloses this in its provenance block, alongside the observation count, the distinct-counterparty count and the external share. At the time of writing is_independent_assessment is false on both networks.
On the testnet the external share reads 1.0 with eight “external” counterparties. That is an artefact of an empty own-account registry: the classifier has no entries there, so it cannot recognise our own keepers and counts them as external by default. It is not evidence of independent participation, and the market overview says so beside the figure rather than leaving it to be inferred.
Every series on the datasheet carries one of three provenance classes. Observed is a re-presentation of chain state — it is what happened. Derived is computed by Aletheia from observed data — it is an assessment, and the response carries the sample size behind it. External is sourced from a third party, named in the response. A fitted curve and a settled auction are not the same kind of fact, so the distinction is published rather than left to be inferred.
