Say what was measured about Medium's reCAPTCHA, not what it is probably for - #2

…ly for Five files described the reCAPTCHA Medium ships as being "for its own sign-in widget". Nothing measured supports the "sign-in" half: what the captures show is `recaptcha/enterprise.js?render=<sitekey>` — the v3 INVISIBLE pattern, which scores page views rather than gating a form — plus two more sitekeys in Medium's own page config, on every page the modern renderer serves. What Medium does with the score is not visible from outside, so the claim is narrowed to what the captures actually show: it is present, it is Enterprise v3 invisible, and it never rendered a challenge to an anonymous reader — 0 `api2/anchor` iframes across four pages known to be good. That is the part that matters here, because it is why `g-recaptcha` and `recaptcha` are kept out of the marker set (§18) and why no run ever treats it as a challenge. The legacy archive renderer carries only the two config keys and not the enterprise loader, which is a third answer from the same site. No behaviour changes. §13: a claim that was inferred rather than measured is the thing this family's documentation is supposed to be free of, and this one shipped in a public README.
