ChainChoice published rankings

Once the reader has agreed to go to a provider (consent: true), returns what to hand over: the provider's own address as ChainChoice's catalog records it (never a referral or affiliate link; ChainChoice earns nothing from it), the product's published rank and ChainChoice Score, the reader's country and monthly volume, the ranked list's page with that setup, whether the provider serves that country, and a receipt signed with ChainChoice's published key (check it with verify_receipt) recording exactly what was handed over. A provider that does not serve the reader's country is not handed off: handedOff is false with the reason. It does not open anything, log the reader or change any ranking.

Checks a signed receipt (as ChainChoice serves it, or an issuer envelope) against the keys ChainChoice publishes: whether its content hash matches and its signature is valid. The same verifier as POST /api/v1/verify.

For one category (and optionally one product id): each criterion, its weight, and per product the score with the quoted passage, its source URL and the day it was read.

The published order of one category: rank, product id, name and ChainChoice Score, with the methodology version, the dimension weights and what was assessed. The same order the category page and rankings.json publish.

The category's products as a reader in one country sees them: those available there, in order, with each one's published score and rank beside it. When nothing passes the country's availability filter, resultMode is "fallback" and the rows are the published order, none confirmed for that country.

Every category ChainChoice ranks, with how many products it ranks, how many it assessed and left out with a reason, its leader, and its page.

Reads a query exactly as ChainChoice's search bars do (the same resolver as the homepage, the navigation field and the command palette) and returns that reading: the page it opens (a category's ranked list with the country, monthly volume, sort and filters read from the words, a product's verdict, a two-product compare, a guide), or the question it asks with at most three options, each with the page it opens; `answer`, the card the bars show before a page opens (the published #1 or the named product, its ChainChoice Score and rank, the margin, why it leads, its main trade-off, the list's page and a link to watch it), every figure from the published ranking; `readBy` when a model read a sentence the rules could not (only while ChainChoice's model tier is on and released by its measured eval); plus `open`, the homepage address that runs the same search. `country` applies a reader's country to a ranked list when the words name none; a country in the words wins. Nobody pays for a place in any answer.
