Why an agent can trust this route.
Sonar evidence is advisory. Paid delivery is shown as verified only when paid probes are available; otherwise route estimates use the unpaid handshake as a clearly labeled proxy.
Observed outcomes
Every Hacker News story over 20 points from the last 24h, ranked by engagement and tagged across eleven topics: AI, devtools, data, infra, security, web, hardware, policy, business, science, culture. A developer_relevant flag keeps the engineering stories and drops the politics and obituaries, about half a typical day. ?since=<ISO-8601> returns only what is new; an empty delta is free. The free listing's coverage block states the window, threshold and whether upstream's page came back full.

An empty delta is refused with a 400 and settles no payment, and so is a since earlier than the build's coverage.delta_complete_since, which would return a silently incomplete delta. This is a 24h window, so poll at least daily."
