 * — argument validation failures, SSRF blocks, network errors, HTTP
 * errors, and timeouts all surface as `ok=false` with a categorical
 * `error.kind` and a human-readable message. The `metadata` field is
 * always populated: pipeline stages that completed before the failure
 * are surfaced (e.g. `resolvedIp` when DNS succeeded but a 4xx came
 * back), and stages that did not run carry default zero/empty values.
