Typed primary-source lookups

Connectors

Every connector this pipeline can call, what question it answers, and whether it can actually answer one in this environment, right now — a live check of an API key or a cached data file, not a description of the code.

Read this before the table. A connector is called only by the Verifier (Stage 3, checking a claim already on file) or a Scout (Stage 0 / 0.5, scanning for what changed) — never by the Scorer, which has no network access at all. A source being unavailable here does not weaken a claim; the claim simply keeps whatever tag it already has, usually unconfirmed — meaning nothing was searched, not searched and found nothing.

`adoption`	Stage 3 · Verifier	stakeholder adoption / preference	none — needs primary market research this repo does not have	unverifiable by design No primary source exists for this claim type.

Three of these will never turn green, on purpose. cpt, market and adoption return unverifiable by design — CPT codes are AMA-licensed and cannot be scraped or reproduced, no free authoritative source prices a market, and no database records what a surgeon or a payer would do. That is a correct, permanent result, not a missing integration.
