description: Scores a domain on agent readiness across 5 funnel stages, using 16 deterministic HTTP checks. 18 points exist on paper; the score is out of `measurable`, the points that both applied and could be evaluated. No account, no key.

description: 'The scan did not finish inside the gateway timeout. /api/scan/stream reports progress and does not go silent. A store that will not accept the write is NOT this: that answers 200 with saved: false, because the measurement is finished and it is yours either way.'
