Thank you for the incredibly thorough architectural breakdown and tracing the exact dispatch lifecycles! That makes total sense: I missed that You are completely right that this predicate change doesn't reach the Regarding the next step:

Correct the policy scope in the comment and provider documentation.
Native /responses passthrough does not call transientRetryPolicyFor. It keeps its fixed three-attempt retry budget. This policy change affects chat-native.ts handling of /v1/chat/completions with an openai-responses adapter.
Describe the supported adapter and reachable route without calling it a passthrough policy. Update docs-site/ because the provider option now applies to key-auth openai-responses providers in this lane, while the existing documentation says it applies only to openai-chat.
As per coding guidelines: “Update docs-site/ when the change affects user-visible behavior or configuration.”

Summary
Extends the transient-5xx replay budget (
transientRetryOn5xx) to key-authopenai-responsespassthrough providers in addition toopenai-chat.Without this gate allowance,
transientRetryPolicyForreturnsnullforopenai-responsesproviders, causing fast transient 502/503 responses on the native/responsespassthrough lane (e.g.opencode-zen/go) to terminate the request on the very first send with an "interrupted with no error" experience on client side instead of using the configured send budget.Changes
