When you ask Atlas Commons a question where being wrong is expensive, the answer is built to a fixed five-layer shape — and each layer carries an explicit epistemic guarantee. The recorded fact, the warrant that makes it legible, the comparison that never becomes a ranking, the route to the official source, and the point where a human must take over. This is the answer-level companion to the Research Object (per-claim citation) and the Data Catalog (per-dataset provenance).
A source-backed figure, traced to a named dataset and carried as a research object with its four-status warrant. Never a vibe, an estimate dressed as a fact, or a number without a source.
The framing a non-expert needs to read the fact correctly: what it is, what it is not, and the caveat that prevents a wrong decision. A bare number can mislead; the meaning layer is correctness, not decoration.
The set of real choices, presented so they can be compared on the figures — never ordered into a "best." Atlas Commons informs and compares; it does not pick for you, because the right choice depends on facts only you hold.
The concrete next step at the authoritative source — where the decision is actually made or the transaction actually happens. The atlas hands off; it never pretends to be the endpoint.
The boundary past which only a person — a doctor, a lawyer, a licensed advisor, the official agency — can responsibly act, stated plainly. The atlas names its own edge.
Ask the Coverage Atlas "what will an ACA plan cost me in Texas?" — a question where being wrong is expensive. The live answer is shaped exactly to the standard:
src:cms:aca-rate-puf:2026.The same shape holds across the network: the Property Atlas pairs a county's realized flood losses (RECORDED NFIP claims) with its modeled FEMA risk, frames the insurance-undercount caveat, and routes to FloodSmart.gov; the Justice Atlas reports a district's civil docket (RECORDED counts, DERIVED shares), bounds it as volume-not-quality, and routes to PACER and to counsel.
A ranking sold as truth. Ordering options into a "best" is an opinion, not a fact — Layer 3 compares, it never decides.
Advice sold as a fact. A per-person verdict drawn from an aggregate (your risk, your odds, your diagnosis) crosses into Layer 5 and is withheld.
An action with no route. A consequential answer that does not hand off to the official source is a dead end — or a trap that keeps you on our surface.
A truth with no source. A figure that cannot be traced to a named dataset is a rumor; it does not ship. On a decision surface, no figure ships without its four-status warrant.
Because it is machine-readable and uniform. An agent that has read this standard knows the shape of every answer in the commons before it fetches one: where the sourced fact is, where the caveat is, that the options are compared and not ranked, where the official route is, and where the answer stops. That is what lets an AI cite an Atlas Commons answer responsibly — and what lets a person trust one. Fetch answer-standard.jsonld for the structured spec.
