Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to This PR enables encrypted child-task passthrough for explicitly trusted providers, but current-head risks remain in routing decisions that may use a provider or default wire instead of the final model-resolved wire, and in settings state that can revoke a valid opt-in during a later save. These can cause task failures or unexpected provider behavior, so the PR needs fixes or explicit owner acceptance before merging. Sequence Diagram(s)sequenceDiagram

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.

Rechecked current head 2f4adb01888bb1a4e664d18b1b1aa702c8c1da52 after the force-push that invalidated my earlier approval.
I am requesting changes for integration state, not reopening the already-fixed encrypted-V2 findings. This branch is now 58 commits behind current dev (3c6a4524be17f4dfac7da6a434cc8365753c94fa), and a three-way merge has real conflicts in the exact security boundary, including src/config.ts, src/providers/openai-tiers.ts, src/server/management/provider-routes.ts, src/server/responses/core.ts, src/types/provider.ts, ProviderSettings, and the corresponding tests/docs.
The intervening dev range includes the routed-destination/opaque-state series (#2258), final-route continuation ownership, the Grok Responses lane changes, and pooled-ciphertext recovery. The previous exact-head security approval and green CI cannot be transferred across those overlaps.
Please rebase onto the latest dev, resolve the conflicts without dropping either side's final-wire and fail-closed invariants, and rerun the focused encrypted-V2 backend/GUI tests, typecheck, privacy scan, GUI build, and exact-head CI. Because this enables a credential/opaque-ciphertext trust boundary, @lidge-jun's explicit exact-head security approval is still required before merge. I will re-review the rebased delta; I will not merge the current stale head.

Re-reviewed current head 6686043ea4efd501d908ddf179253f4a9ed904f2. I am not reopening the previously fixed final-wire, fail-closed config, or GUI confirmation-state findings. This exact head is still not mergeable: GitHub reports CONFLICTING / DIRTY, it overlaps the current Responses/config security boundary, and the previous security approval and CI belonged to older heads.
One current documentation thread also remains unresolved: the French and Turkish sub-agent guidance and the Traditional Chinese proxy-format eligibility text still contradict the new explicit encrypted-V2 opt-in contract. Synchronize those maintained locales.
Please rebase onto current dev, resolve the config/provider/Responses/GUI conflicts without dropping the final normalized adapter guard or explicit-confirmation semantics, update the remaining locales, then rerun the encrypted-V2 backend/GUI tests, typecheck, privacy scan, GUI build, and exact-head CI. Because this enables opaque ciphertext on a new trust boundary, @lidge-jun’s explicit exact-head security approval is still required before merge.

Re-reviewed exact head 6686043. The existing conflict, locale-thread, exact-head CI, and owner-security-approval blockers remain. I found one additional destination-trust blocker on this head.
The encrypted-task opt-in is retained when the concrete provider destination changes. applyProviderPatchFields clones the existing provider and PATCHing only baseUrl preserves allowEncryptedV2AgentTasks: true. The management validators only check that the adapter remains openai-responses, and canReceiveEncryptedV2AgentTasks later authorizes the retained flag without binding it to the new base URL.
I reproduced this with an opted-in provider at https://relay.example.test/v1 and a PATCH containing only a new baseUrl. The request returned 200, and both live and persisted config held the new destination with allowEncryptedV2AgentTasks still true. The GUI has the same gap: create and edit flows confirm only the checkbox transition; changing the endpoint picker or Base URL afterwards does not clear or reconfirm the trust decision.
This means endpoint A can be verified and approved, then endpoint B can inherit opaque V2 child-task ciphertext without a destination-specific opt-in. The final-wire guard still blocks incompatible adapters, but it cannot tell that the approval belonged to a different upstream.
Please bind this trust decision to the effective normalized destination. At minimum, a baseUrl change must clear allowEncryptedV2AgentTasks unless a fresh explicit opt-in is performed for the new endpoint. Apply the rule at the management boundary as well as the GUI so non-GUI PATCH callers cannot retain stale trust. Add regressions for create-after-confirm endpoint mutation, editing an already opted-in provider to a new URL, and a baseUrl-only management PATCH proving the capability becomes disabled before any ciphertext can be forwarded.
Focused verification on this head: backend encrypted-V2/config/management suites passed 312 tests with 2 platform skips; GUI encrypted-V2 tests passed 6/6; typecheck, privacy scan, and GUI build passed. GUI oxlint could not run in this isolated worktree because the installed dependency set lacks the oxlint binary. This does not change the blocker above.

One additional fail-closed correctness gap exists on exact head 6686043. It does not leak ciphertext, but it breaks the intended eligible fallback behavior.
When a virtual alias has an alias-level openai-chat modelAdapters override but its base wire model has no override, routeCanReceiveEncryptedV2AgentTasks virtualizes the alias first and checks only the base-model adapter. Preflight therefore considers the alias eligible under the provider-wide openai-responses adapter. Final route normalization applies the alias override before virtualizing, so the authoritative gate later sees openai-chat and returns unreadable_encrypted_agent_task.
For subagent fallback, the first provisionally eligible alias is returned and no later fallback candidate is considered after the final 400. For combos, the child 400 is terminal under comboFailureDecision, so a later eligible Responses target is also skipped.
A minimal case is an opted-in openai-apikey provider with modelAdapters containing only gpt-5.6-sol-pro: openai-chat, followed by a trusted relay/gpt-5.6-luna fallback or combo target. The first candidate is selected, then rejected locally, and the relay is never attempted.
Please make preflight eligibility use the same adapter-normalization order as final dispatch: apply the selected-alias override, resolve the virtual wire model, then apply any wire-model override. Add fallback and combo regressions with only the alias-level override and prove the later eligible target is selected. The current two-direction tests configure both alias and base overrides, so they do not cover this case.

One reportable security-boundary finding is confirmed:
- Provider destination changes inherit encrypted-task trust without fresh confirmation.
applyProviderPatchFieldsclones the existing provider, permits abaseUrl-only change, and preservesallowEncryptedV2AgentTasks: trueunless the PATCH explicitly carries that field. The final capability predicate later authorizes the new Responses destination using that retained boolean. I reproduced the exact management mutation: the PATCH succeeded and both live and persisted config contained the new URL with the old trust bit. The GUI has the same consent-provenance gap because endpoint/Base URL changes do not clear or reconfirm the checkbox. This is low severity because the mutation requires authenticated management authority and the unintended destination receives opaque ciphertext rather than demonstrated plaintext or credentials, but it violates the destination-specific trust contract and must be fixed before merge. Clear the capability whenever the effective normalized destination changes, require a separate explicit re-enable for the new endpoint, enforce this at the management boundary as well as the GUI, and add baseUrl/endpoint-change plus unchanged-destination regressions.
One additional merge blocker is correctness/availability rather than a reportable vulnerability:
- Virtual-alias preflight and final normalization can disagree. With only an alias-level
openai-chatoverride, provisional encrypted-task eligibility can select that alias under provider-wide Responses, while final normalization applies the alias override first and rejects it locally. The later eligible fallback or combo target is then skipped. The authoritative final gate prevents ciphertext from leaving the process, so this is not a confidentiality bypass, but preflight must use the same alias-override -> virtual-wire-model -> wire-model-override order as final dispatch, with fallback and combo regressions.
Independent exact-head verification completed:
- backend focused suites: 312 passed, 2 platform skips, 0 failed;
- encrypted-V2 GUI suites: 6 passed, 0 failed;
- typecheck: passed;
- privacy scan: passed;
- GUI production build: passed;
- GUI i18n lint with the pinned
oxlintdependency: passed.
The branch is also still CONFLICTING / DIRTY against current dev 7881319e7df5cd21276d8fa2fc82d6739e3d23ab, including overlaps in the provider/Responses security boundary; it has no exact-head cross-platform CI, the translated-guidance thread remains unresolved, and git diff --check reports the extra EOF blank line in the Turkish provider configuration page.
Rebase onto current dev, preserve the already-correct final adapter fail-closed gate and config salvage behavior, fix both blockers and the maintained locales, then rerun the focused suites, typecheck, privacy scan, GUI build/lint, and full exact-head CI. Because this introduces a new opaque-ciphertext trust boundary, @lidge-jun explicit security approval is still required on the corrected exact head. Automated/Grok findings were treated as advisory input and independently verified.

Summary
allowEncryptedV2AgentTaskscapability for non-canonicalopenai-responsesproviders whose upstream has been explicitly verified to consume or relay opaque V2 child-task ciphertext.Related to #92. Complements #1540, #1556, and #1794; this capability does not replace plaintext task recovery.

Compatibility checks against the
v2.26.0tag also passed focused tests, typecheck, GUI production build, and package build. Manual end-to-end verification confirmed that a non-canonical Responses provider can complete a V2 spawned child task after the explicit opt-in is enabled.Full-suite context
All change-relevant local CI gates are green. The repository-wide backend suite is not clean on this Windows/Bun 1.3.14 host for failures that were independently reproduced from a detached worktree checked out to clean
origin/devwithout this PR. The stable baseline failures were Windows identity/ACL and process-timing cases, hard test timeouts, and one Bun panic; no reproduced failure was in a path changed by this PR. This PR therefore reports the complete baseline context while using the green PR-focused backend suite and final exact regressions as its local readiness signal. GitHub CI remains authoritative for the repository-wide exact-head gates.Screenshots
