Questions
Does StepFun have zero data retention?
TrustedRouter does not currently mark StepFun as provider-level zero data retention. Use trustedrouter/zdr or provider.min_privacy=zdr to select a different eligible route, and review the linked policy source for changes.
Is StepFun end-to-end encrypted?
TrustedRouter does not currently mark StepFun as end-to-end encrypted at the provider boundary. The TrustedRouter gateway is still attested, but the selected provider normally receives the request in order to run the model. Use trustedrouter/e2e for the stronger route requirement.
