Arrival evidence (#434, product redact-secret#907; #860 handoff helicone.md, READY). The write-only key can send requests and logs into the org; no provider source says it is safe to publish (unlike PostHog phc_ or Stripe pk_), so the handoff detects and redacts it under its own type, which a user policy can downgrade. It may appear in the gateway URL path (https://gateway.helicone.ai/<key>/v1/), where / delimits it. Neither pinned peer has a Helicone rule.
What the run recorded, by group
Detector views overlap, so their groups are never summed across detectors. Other scanners are reference values on the same inputs, in run order.
