Summary

  • Add a disabled-by-default allowEncryptedV2AgentTasks capability for non-canonical openai-responses providers whose upstream has been explicitly verified to consume or relay opaque V2 child-task ciphertext.
  • Apply eligibility consistently to direct routing, combo selection, sub-agent fallback, and recovery dispatch. Canonical ChatGPT forwarding remains implicitly eligible, while every other ineligible route stays fail-closed.
  • Expose the opt-in in both Add Custom Provider and Provider Settings with an explicit confirmation, validate it at config and management boundaries, and document the trust model in the English reference while keeping the UI copy localized.

Related to #92. Complements #1540, #1556, and #1794; this capability does not replace plaintext task recovery.

Behavior

  • Canonical ChatGPT forwarding remains implicitly eligible without a provider flag.
  • A non-canonical Responses provider remains blocked with unreadable_encrypted_agent_task unless the opt-in is enabled.
  • An opted-in Responses provider receives the original opaque task unchanged, and plaintext recovery is skipped for that dispatch.
  • Eligibility is evaluated after model-specific wire resolution, so a modelAdapters override to openai-chat remains blocked even when the provider is opted in.
  • Non-Responses adapters cannot enable the capability.
  • Changing the adapter away from openai-responses clears the create-form opt-in so stale state cannot be submitted.

Security

  • The capability is disabled by default and requires an explicit confirmation in the GUI.
  • Eligibility is never inferred from a provider name, model name, or custom base URL.
  • The flag authorizes passthrough only; OpenCodex does not decrypt, translate, or recover the payload, or claim that an unverified upstream is compatible.
  • Management and startup validation reject invalid combinations, and provider DTOs continue to omit credentials.

Test plan

  • 45 focused encrypted-V2 routing tests passed with 0 failures on the rebased final head: tests/v2-agent-message-failfast.test.ts (30), tests/github-copilot-encrypted-origin.test.ts (3), management destination/capability stale-state cases (2), and encrypted sub-agent fallback/combo cases (10).
  • PR-relative React Doctor passed: bun x --yes react-doctor@0.9.11 --verbose --scope changed --base origin/dev --no-telemetry scanned 18 changed files with no issues.
  • git diff --check origin/dev...HEAD passed, and the committed diff contains no test Base URL or local workspace path used during manual verification.
  • Local Cross-platform-CI equivalents also exposed two current-dev baseline issues outside this PR's diff: bun run typecheck rejects RequestInit.timeout in existing claude-messages.ts / responses/fetch-helpers.ts, and two unmodified Anthropic account-pool tests exceeded their default 5-second threshold when run serially. These are recorded as baseline/local-environment findings, not represented as PR regressions.
  • Manual end-to-end verification confirmed a non-canonical Responses provider completed a V2 spawned child task after the explicit opt-in.

Verification

Verified on exact head f38f5d37e rebased onto dev df8b3882:

  • 45 focused encrypted-V2 routing tests passed with 0 failures.
  • PR-relative React Doctor completed with no issues.
  • git diff --check origin/dev...HEAD passed.
  • The committed tree contains no manual-test Base URL, local path, or credential.
  • The Cross-platform-CI local-equivalent baseline caveats above are not in the PR diff.

📝 Walkthrough

Walkthrough

Encrypted V2 child-task routing now supports explicitly enabled openai-responses providers for opaque ciphertext forwarding. The change adds provider validation, management persistence, GUI controls, capability-aware fallback and combo routing, origin-safe transport checks, regression tests, and localized documentation.

Changes

Encrypted V2 passthrough

Layer / File(s) Summary
Provider capability and management
src/types/provider.ts, src/config.ts, src/providers/..., src/server/management/..., tests/*
Adds and validates allowEncryptedV2AgentTasks. Provider APIs persist and expose the setting. Destination changes revoke approval. Transport resolution uses the configured destination for key-auth providers.
Encrypted task routing
src/server/responses/core.ts, src/codex/subagent-model-fallback.ts, src/server/adapter-resolve.ts, tests/*
Uses inbound wire, final wire resolution, approved origins, and provider capability to select fallback and combo targets. Eligible Responses providers receive ciphertext unchanged. Ineligible routes fail with unreadable_encrypted_agent_task.
Provider settings UI
gui/src/components/..., gui/src/provider-payload.ts, gui/src/provider-workspace/..., gui/src/i18n/*, gui/tests/*encrypted-v2*
Adds a default-off, confirmation-gated setting for openai-responses. Endpoint and adapter changes clear the setting. Payload construction persists it only when applicable.
Encrypted task documentation
docs-site/src/content/docs/**
Documents opaque forwarding, provider trust, final wire checks, fallback and combo routing, recovery behavior, and fail-closed errors across locales.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to b090e

The change enables explicitly trusted opaque V2 task passthrough, but current routing behavior may still evaluate an opted-in provider using the wrong final wire or stale fallback origin, causing child tasks to fail or reach an incompatible backend. These bounded correctness and availability risks should be fixed or explicitly accepted before merge; the remaining documentation and localization issues are lower-severity follow-up items.

리뷰 · 우선순위 32 / 80

신뢰한다고 표시한 커스텀 Responses 프로바이더에게, 암호화된 V2 서브에이전트 태스크를 그대로 넘겨주는 opt-in이다. 설정 키는 OcxProviderConfig.allowEncryptedV2AgentTasks이고 기본값은 unset/false다. Zod(src/config.ts)는 true인데 adapter !== "openai-responses""allowEncryptedV2AgentTasks requires adapter=openai-responses"로 거절한다. 정규 ChatGPT forward 경로는 플래그 없이도 지금이랑 같다. 아이디어는 V2/서브에이전트 방향이랑 맞아서 한 48까지는 볼 수 있지만, 지금 머지 점수는 32다. 기본 경로 장애가 아니라 꺼져 있는 보안 경계를 여는 일이고, draft + intake: hygiene-blocked + 체크리스트 0/4다.

실제로 연 건 복호화가 아니다. OpenCodex는 ciphertext를 풀지 않는다. src/server/responses/encrypted-payload.tshasUnreadableEncryptedAgentTask()는 그대로다. 꼬리 agent_message에 Fernet encrypted_content가 있고 읽을 수 있는 태스크 텍스트가 없으면 unreadable로 본다. src/server/responses/core.ts는 여전히 HTTP 400, invalid_request_error, unreadable_encrypted_agent_task를 만든다. 이 PR이 바꾼 건 누구를 통과시키느냐다. 최종 라우트는 !canReceiveEncryptedV2AgentTasks(route.provider) && unreadableEncryptedAgentTask일 때만 400이다.

적격 판정은 src/providers/openai-tiers.tscanReceiveEncryptedV2AgentTasks() 한곳으로 모였다. 정규 프로바이더(adapter === "openai-responses" && authMode === "forward" && baseUrl === CODEX_FORWARD_BASE_URL)이거나, openai-responses이면서 플래그가 진짜 true일 때만 통과한다. 이름이나 URL로 추측하지 않는다. 콤보 픽, 서브에이전트 fallback(src/codex/subagent-model-fallback.tsnativeFallbackOnly), recovery skip, 최종 라우트 reject가 전부 이 헬퍼를 본다. 중요한 차이: 옵트인 통과 경로에서는 recoverEncryptedAgentTask / agentTaskRecovery를 건너뛴다. 불투명 ciphertext를 업스트림에 그대로 보내는 신뢰 모드고, plaintext를 되살리는 모드가 아니다.

GUI도 그 경계를 따른다. Add Custom Provider랑 Provider Settings는 비정규 openai-responses일 때만 체크박스를 보여 주고, 켜려면 window.confirm(t("pws.encryptedV2Confirm"))를 통과해야 한다. 어댑터를 openai-responses 밖으로 바꾸면 플래그를 지운다. 정규 openai 설정에는 체크박스가 없다. gui/src/provider-payload.ts는 어댑터가 openai-responses이고 true일 때만 플래그를 보낸다. management PATCH(src/server/management/provider-routes.ts)는 boolean을 요구하고, 리스트 DTO는 allowEncryptedV2AgentTasks: p.allowEncryptedV2AgentTasks === true로만 노출한다.

auth-cors.ts를 건드린 건 CORS origin 정책이 아니다. providerManagementConfigError()에 boolean/adapter 체크를 넣고, safeConfigDTO() allowlist에 플래그를 올린 거다. 그래도 경로가 src/server/auth-cors.ts라서 hygiene이 unsponsored_surface를 붙인다. 보안 리뷰의 질문은 문서 분량이나 GUI confirm이 아니다. ChatGPT용 암호문을 비정규 Responses baseUrl로 보내도 되는가다. 호환은 증명되지 않았고, 비-Responses 어댑터는 이 플래그를 켤 수 없다. 55파일 중 런타임 축은 src/types.ts, src/config.ts, src/providers/openai-tiers.ts, src/server/responses/core.ts, src/codex/subagent-model-fallback.ts, src/server/auth-cors.ts, src/server/management/provider-routes.ts, GUI 몇 개다. 나머지는 대부분 locale/docs다.

그래서 지금은 머지하지 않는 게 맞다. 메인테이너가 스폰서하고, auth-cors 검증만 더 작은 서피스에서 빼고, 체크리스트 4칸을 채운 뒤에 다시 보면 된다. 전체 backend suite는 Windows에서 안 돌렸다고 적혀 있으니 그걸 전제로 리뷰하면 안 된다. 지금은 Windows native-main / 2.26.0 안정화(#2108)가 먼저다.

해결방안

머지 경로를 짧게 쓰면 이렇다. 1) src/server/auth-cors.ts에 얹은 검증/DTO allowlist를 전용 management 검증 모듈로 옮겨 unsponsored_surface를 풀거나, 메인테이너가 보안 리뷰 후 maintainer-sponsored를 단다. 2) 비정규 Responses로 ciphertext를 보내는 신뢰 모델을 한 문장으로 고정하고, 플래그가 켜진 경로에서 plaintext recovery를 건너뛰는 이유를 테스트로 고정한다. 3) draft를 해제하고 체크리스트 4칸을 채운 뒤 CI 전체 스위트를 통과시킨다. 그 전엔 점수 32에서 올리지 않는다.

Inline comments:
In `@docs-site/src/content/docs/ja/guides/sub-agent-surface.md`:
- Around line 85-86: Update the unavailable-target sentence in the Japanese
guide so it uses grammatically correct wording such as “利用可能なターゲットがない場合,” while
preserving the existing condition that a 400 error is returned.
- Line 79: Update the Japanese issue reference in the affected documentation
sentence so the label clearly means “limitation `#92`,” using “#92 の制限” or an
equivalent natural phrasing while preserving the existing link and surrounding
meaning.

In `@docs-site/src/content/docs/ko/guides/sub-agent-surface.md`:
- Around line 79-90: Update the stale encrypted child-task routing statement in
the Korean guide so it no longer restricts routing to canonical native ChatGPT
targets; also include Responses providers explicitly configured with
allowEncryptedV2AgentTasks: true, matching the behavior described in the
surrounding section and English source.

In `@docs-site/src/content/docs/reference/proxy-formats.md`:
- Line 297: Update the unreadable_encrypted_agent_task and related hygiene
descriptions to recognize trusted openai-responses targets that forward
encrypted payloads opaquely without decryption or translation. Apply the
distinction in docs-site/src/content/docs/reference/proxy-formats.md lines 297
and 313-314, docs-site/src/content/docs/ko/reference/proxy-formats.md lines 264
and its related hygiene description, and
docs-site/src/content/docs/ru/reference/proxy-formats.md lines 273 and its
related hygiene description; state failure only when no canonical consumer or
explicitly trusted opaque-passthrough target exists.

Apply the same fix in
`@docs-site/src/content/docs/zh-tw/guides/sub-agent-surface.md` around lines 90 -
109: Qualify both external-route failure statements with the explicit opt-in
exception.

In `@docs-site/src/content/docs/ru/guides/sub-agent-surface.md`:
- Line 122: In the documentation sentence containing “завершаетcя”, replace the
embedded Latin c with the Cyrillic с, preserving the surrounding text.

In `@gui/src/i18n/en.ts`:
- Around line 1188-1189: Update the pws.encryptedV2PassthroughDesc and
pws.encryptedV2Confirm translations to describe providers that may consume or
relay opaque V2 child-task ciphertext, and state that OpenCodex does not
decrypt, translate, or recover the payload. Preserve the existing
provider-compatibility warning and opt-in context.

In `@gui/src/i18n/ko.ts`:
- Around line 1712-1714: Update the Korean strings
pws.encryptedV2PassthroughDesc and pws.encryptedV2Confirm to use the existing
프로바이더 terminology instead of 공급자, preserving the rest of each translation
unchanged.

In `@gui/src/i18n/tr.ts`:
- Around line 1178-1180: Update the Turkish strings pws.encryptedV2Passthrough
and pws.encryptedV2Confirm to use “alt ajan görevleri” instead of “aracı
görevleri”; leave pws.encryptedV2PassthroughDesc unchanged unless it contains
the same agent-task terminology requiring consistency.

In `@src/providers/openai-tiers.ts`:
- Around line 44-46: Update canReceiveEncryptedV2AgentTasks and all listed call
sites to base encrypted-task eligibility on the final resolved model wire,
permitting only openai-responses. In src/providers/openai-tiers.ts:44-46,
src/config.ts:1406-1412, src/server/auth-cors.ts:573-578,
src/codex/subagent-model-fallback.ts:285, and src/server/responses/core.ts:1403,
1958, and 2050, ensure incompatible openai-chat overrides fail closed before
forwarding or skipping recovery. Add coverage in
tests/openai-provider-option.test.ts:41-71 and
tests/v2-agent-message-failfast.test.ts:226-303 for direct and combo routing
with an opted-in provider resolving to openai-chat; other adapters remain
ineligible.

In `@docs-site/src/content/docs/guides/sub-agent-surface.md`:
- Around line 128-133: Update the direct non-native route statement in the
opencodex failure-safety documentation to limit the HTTP 400 behavior to routes
that are neither eligible canonical ChatGPT targets nor explicitly trusted
Responses targets; preserve the documented forwarding behavior for trusted
openai-responses routes.
- Around line 140-147: Update the provider and adapter reference documentation
to describe encrypted V2 passthrough: document the disabled-by-default
allowEncryptedV2AgentTasks opt-in for explicitly trusted non-canonical providers
whose final wire is openai-responses, canonical ChatGPT eligibility without the
flag, and fail-closed behavior for other routes including openai-chat overrides.
In the adapter references, including the ja, ko, ru, and zh-cn counterparts,
state that encrypted V2 task content remains opaque and is neither decrypted nor
translated, while preserving the existing authentication and raw passthrough
details.

In `@docs-site/src/content/docs/reference/proxy-formats.md`:
- Line 297: Update the localized encrypted-task descriptions and nearby
explanations in the ja, ko, ru, and zh-cn proxy-format documents to state that
explicitly trusted Responses targets may also consume or relay the ciphertext
opaquely, alongside eligible canonical ChatGPT consumers. Keep the wording
consistent with the `unreadable_encrypted_agent_task` definition and update only
the affected localized entries.

In `@gui/src/i18n/ko.ts`:
- Around line 1713-1714: Update the Korean strings
pws.encryptedV2PassthroughDesc and pws.encryptedV2Confirm to clearly describe
the task as already opaquely encrypted, not as an encryption operation, and
state that incompatible endpoints may fail because they cannot read the task.

In `@gui/tests/provider-settings-encrypted-v2.test.tsx`:
- Line 24: Update the confirmation setup in the provider settings tests to track
calls and explicitly cover both approval and cancellation. Add assertions that
confirmation is requested before enabling the trust setting, and that the
cancellation path does not save a patch containing allowEncryptedV2AgentTasks:
true; preserve the existing approved-path verification.

docs-site/src/content/docs/ko/guides/sub-agent-surface.md:79-79 so they state
that verified Responses providers configured with allowEncryptedV2AgentTasks:
true may consume or relay opaque encrypted ciphertext, matching the English
source and explicit opt-in behavior.

Rebased and force-pushed the PR to the current dev at f38f5d3 (base df8b388). Focused encrypted-V2, final-wire, Copilot-origin, management, and fallback coverage: 45 passed, 0 failed. PR-relative React Doctor passed (18 changed files, no issues). Verification now records the current-dev, PR-external local typecheck and account-pool timing caveats explicitly; no runtime, docs, or i18n scope was split out. The review-readiness checklist remains fully checked. @coderabbitai review @Ingwannu @lidge-jun Please re-review this exact head when convenient.

@cb8010d6 No blocking or actionable finding remains in exact head f38f5d37e7e41e26fb78ec4813d69be77b1316d2.

The head descends from dev@df8b3882f221b3d68eddcfc34cc3a6edccbb32b3. git diff --check df8b3882...HEAD is clean.

The exact-head commit only removes trailing whitespace from docs-site/src/content/docs/tr/reference/proxy-formats.md. It does not change runtime behavior, documentation meaning, or localization content.

The encrypted V2 boundary remains fail-closed.

  • src/providers/encrypted-v2-transport.ts, Lines 24-37, resolves the effective transport, requires its origin to match the approved baseUrl origin, resolves the final wire protocol, then applies canReceiveEncryptedV2AgentTasks().
  • src/providers/openai-tiers.ts, Lines 76-79, permits canonical ChatGPT forwarding or an explicit openai-responses opt-in only.
  • src/server/responses/core.ts, Lines 2193-2198, filters encrypted combo candidates through the shared policy.
  • src/server/responses/core.ts, Lines 2925-2934, skips plaintext recovery when the final route can receive the opaque ciphertext.
  • src/server/responses/core.ts, Lines 3091-3097 and Lines 3354-3360, reject an ineligible route before dispatch and again after authentication.
  • src/server/responses/core.ts, Lines 4127-4139 and Lines 5799-5810, revalidate the route after OAuth refresh.
  • src/codex/subagent-model-fallback.ts, Lines 345-365 and Lines 598-628, applies the same policy during encrypted fallback selection and forwards inboundWire.

The management and GUI boundaries remain consistent.

  • src/server/management/provider-capability-config.ts, Lines 25-37, requires a boolean value and restricts enabled capability use to adapter === "openai-responses".
  • src/server/management/provider-routes.ts, Lines 189-200, clears the approval after a base URL-only change.
  • src/server/management/provider-routes.ts, Lines 799-805, rejects a capability-only PATCH replay when the destination changed during validation.
  • gui/src/components/add-provider-form-pane.tsx, Lines 43-49 and Lines 81-87, clears the opt-in on an endpoint or incompatible adapter change.
  • gui/src/components/provider-workspace/ProviderSettings.tsx, Lines 260-271, persists the opt-in only for openai-responses.
  • gui/src/provider-payload.ts, Lines 106-107, includes the field only when it is enabled for openai-responses.

GitHub reports zero unresolved CodeRabbit review threads.

I performed static inspection only. I did not independently run the stated focused tests, React Doctor, or typecheck. The requested owner/security review remains with @lidge-jun.

@cb8010d6 No blocking or actionable finding remains in exact head f38f5d37e7e41e26fb78ec4813d69be77b1316d2.

The branch descends from dev@df8b3882f221b3d68eddcfc34cc3a6edccbb32b3. Both the PR range and the exact-head patch pass git diff --check.

The exact-head commit changes only trailing whitespace in docs-site/src/content/docs/tr/reference/proxy-formats.md. It has no runtime, documentation-content, or localization effect.

The encrypted V2 route policy remains fail-closed:

  • src/providers/encrypted-v2-transport.ts, Lines 24-37, resolves the effective transport, compares its origin with the approved baseUrl origin, resolves the final wire protocol, then calls canReceiveEncryptedV2AgentTasks().
  • src/providers/openai-tiers.ts, Lines 76-79, allows only canonical ChatGPT forwarding or an explicit openai-responses opt-in.
  • src/server/responses/core.ts, Lines 2193-2198, filters encrypted combo targets through the shared policy.
  • src/server/responses/core.ts, Lines 2925-2934, runs plaintext recovery only when the final route is ineligible for opaque ciphertext forwarding.
  • src/server/responses/core.ts, Lines 3091-3097 and Lines 3354-3360, reject an ineligible final route before dispatch and after authentication.
  • src/server/responses/core.ts, Lines 4119-4139 and Lines 5791-5810, repeat the route validation after OAuth refresh.
  • src/codex/subagent-model-fallback.ts, Lines 345-365 and Lines 598-628, applies the same policy to encrypted fallback candidates and preserves inboundWire.

The management regression coverage includes opt-in persistence, automatic revocation after a destination-only change, explicit reapproval for a new destination, rejection for incompatible adapters, and rejection of a capability-only PATCH replay after a concurrent destination change.

GitHub reports zero unresolved CodeRabbit review threads.

I performed static inspection only. I did not independently run the stated focused suites, React Doctor, or typecheck.

Approved exact head f38f5d37e7e41e26fb78ec4813d69be77b1316d2 as the current implementation/security-boundary review.\n\nThe series is patch-equivalent to the previously reviewed feature through the destination-consent fixes, and the rebased deltas preserve current dev provider validation rather than weakening it. The final policy is centralized in canRouteEncryptedV2AgentTasks: it resolves the transport destination, requires the resolved origin to match the operator-approved origin, resolves the final virtual-model wire adapter, and admits only canonical ChatGPT forwarding or an explicit Responses opt-in. Direct, combo, fallback, pre-auth, post-auth, and both OAuth-refresh replay paths all reuse that fail-closed predicate. Management PATCH clears trust on a destination-only change and rejects a capability-only replay after a concurrent destination change; the React forms clear or require re-confirmation on endpoint/adapter changes.\n\nIndependent exact-head validation under isolated temporary homes: the five backend suites pass 181 with 2 platform skips and 0 failures; the two GUI confirmation/reset suites pass 9/9; bun run typecheck passes; git diff --check is clean; and GitHub reports zero unresolved review threads. No repository-wide security scan was run.\n\nThis is not a merge signal by itself. The branch currently inherits the repository version-line transition while #3006 is still pending; require a fresh rebase after that lands, fully green exact-head Cross-platform CI, and lidge-jun exact-head owner/security approval before merge.
