When a thread-spawn request has any configured subagentModelFallback chain, the earlier applySubagentModelFallback(..., unreadableEncryptedAgentTask, ...) still enables nativeFallbackOnly, whose candidate loop rejects every non-canonical provider. Consequently, an opted-in Responses primary is skipped in favor of the first healthy canonical OpenAI fallback before this passthrough check runs, silently sending the task to a different provider; if no canonical candidate is usable, selection falls back to the primary only accidentally. Treat allowEncryptedV2AgentTasks routes as ciphertext-capable during fallback selection, not only after the route has settled.
Useful? React with 👍 / 👎.

RPM is converted to an even interval; `minIntervalMs` may impose a longer interval.

Set `http1.1` when a provider's HTTP/2 SSE stream stalls instead of delivering events — the symptom is a long-running streaming request that produces nothing and eventually times out. For Cursor, `http1.1`/`h1` selects its `RunSSE` + `BidiAppend` compatibility transport for inference and also pins live model discovery.

Document the final wire eligibility rule.
Line 111 describes only a direct openai-responses provider. Runtime eligibility instead requires a key-auth route whose final resolved adapter is openai-responses. Therefore, a model-level openai-responses override can qualify, while a model-level openai-chat override must fail closed.
State that this is an explicit custom-provider opt-in, the default is disabled, built-in presets do not enable it, existing provider fields must be preserved, and the user must reload or restart after editing the configuration.
As per coding guidelines, “Document current shipped or intentionally pending behavior.” As per path instructions, “Avoid implying that OAuth, Chat adapters, or model-level Chat overrides qualify.”

Assert the exact encrypted payload field.
Line [200] checks only that FERNET_TASK appears somewhere in the serialized body. A regression could rewrite or wrap the ciphertext and still pass, while violating the passthrough contract. Parse forwardedBodies[0] and assert that the encrypted_content part equals FERNET_TASK exactly.
Proposed test assertion

I reproduced a release-blocking interaction on exact head 560bc2aa5.
With an eligible key-auth openai-responses relay (allowEncryptedV2AgentTasks: true) as the requested primary and subagentModelFallback: ["gpt-5.5"], an encrypted thread-spawn task should make one request to the relay. Instead it makes one request to https://chatgpt.com/backend-api/codex/responses; the relay is never called.
The cause is ordering at src/server/responses/core.ts:3074-3085: applySubagentModelFallback(..., unreadableEncryptedAgentTask, ...) receives true as nativeFallbackOnly before canPassThroughEncryptedV2AgentTask() is consulted. selectAvailableSubagentModel() consequently skips the otherwise eligible trusted primary and selects a native model. The new opt-in therefore stops working whenever a fallback chain exists, even though the primary is healthy.
Please make initial encrypted-task selection treat an eligible opted-in direct Responses route as consumable, or preserve the current route before applying native-only fallback. Keep combo attempts excluded and keep OAuth, Chat adapters, and Chat model overrides fail-closed. Add a regression with the trusted relay as primary plus a configured native fallback, asserting the exact encrypted input reaches only the relay and no canonical ChatGPT fetch occurs.
The two existing CodeRabbit follow-ups are also worth closing: compare the parsed encrypted_content exactly in the combo regression, and document that eligibility is based on the final resolved adapter/model override plus the required reload/restart. Once these are fixed, exact-head CI should be rerun before approval.

Summary
Opt-in direct passthrough of encrypted V2 sub-agent tasks. A direct key-auth Responses provider that sets
allowEncryptedV2AgentTasks: trueforwards an opaque encrypted V2 task byte-unchanged instead of falling into agent-task recovery (which returned 400 for a task OpenCodex cannot decrypt). Every other route keeps today's behavior: OAuth providers, the Chat adapter, a model-level Chat wire override, and combo attempts (!options.comboAttempt) all stay on the existing recovery / fail-closed path. Default is off; there is no registry seed, so no built-in preset can enable it.Files:

src/server/auth-cors.ts. The change is a single row classifying a new non-secret boolean as"editor". It adds nothing toREDACTED_PROVIDER_FIELDSand removes nothing; no credential, token, or secret becomes readable or writable through the management API that was not already. No CORS origin, auth mode, or session check is touched. The runtime trust boundary incore.tsis narrow by construction: passthrough requires the inbound wire to be Responses, an explicit provider opt-in (strict!== truecheck),authModeresolving tokey, and the model's final resolved wire override still beingopenai-responses. OpenCodex neither decrypts nor translates the task — the ciphertext is forwarded byte-unchanged (expect(forwardedInput).toEqual(input)).
