In `@src/server/index/websocket-handler.ts`:
- Line 223: Move the ws.data.nativeSteering assignment out of the pre-admission
path and place it only after warmup handling and successful turn admission,
before asynchronous processing begins. Ensure both the generate === false path
and admission-failure path leave no retained steering channel, while preserving
continuation handling in the surrounding websocket request flow.
In `@src/server/responses/native-steering-replay.ts`:
- Line 74: Update the replay prefix construction in the response-created
handling flow to avoid spreading retained arrays into push as positional
arguments. Append previousOutput, committed item inputs, and explicitInput
iteratively or through safe array concatenation so large inputs remain below the
replay limit without triggering Bun’s argument-count RangeError.

Clear unstarted and superseded channel ownership, append bounded replay without argument spreading, and add six red-to-green regressions. Consolidate architecture notes into short links and document native control helpers. Preserve the maintainer-integrated dev branch without rewriting its history.

Validation jobs and exact source artifacts: https://github.com/luvs01/opencodex/actions/runs/35079135199 . Successful, maintainer-preserving publication: https://github.com/luvs01/opencodex/actions/runs/35080467954 . The first run's red overall status comes from the obsolete publication job refusing the concurrent branch change, not from failed validation. The PR description now records the exact scope, source identity and remaining gates. Keeping Draft, as requested. This does not claim a live Astra/App/CLI smoke test, complete upstream CI matrix or independent maintainer/security approval. The previous Codex review request reached its review-usage limit; no paid credit change was made. Only the supported latest-dev and resolved-findings readiness boxes were checked.

Implemented the requested real The child adds a separate default-off injection owner with actual same-account/socket forwarding, serialized acknowledgements, response-completion races, duplicate-result protection, accepted-result replay, and explicit caller-controlled continuation after Current child-source verification with project-pinned Bun 1.4.0 passed on Linux, macOS and Windows: 459 pass / 1 existing conditional skip / 0 fail per OS, including 36 injection tests; typecheck, privacy/architecture/file-size gates and the 449-page documentation build passed. Exact source identity and guarded publication: https://github.com/luvs01/opencodex/actions/runs/35178934345 . Please review the injection-only delta linked in #4858 and land this parent first. Full repository CI, independent security review and live compatible-client/backend smoke tests remain open; synthetic transport coverage is not ChatGPT subscription or Astra certification. |

Fork CI on head 76d7452 (run 35090390226) finished red, but the failures are outside this PR's scope:
On the structure-footnote point from the review: the repeated ownership notes were already condensed to canonical owner-page links in ce26f3e; happy to trim further if you want them gone entirely rather than linked. |

Reviewed as the base of a four-deep stack, alongside #4858, #4861 and #4864. Audit unit: #4882 ( 1. The stack should be stacked. #4858 → #4861 → #4864 → #4868 are all commit-descendants of this branch, but every one of them declares base 2. No repository CI has run at this head. At 3. The canonical route's wire is unproven from any source we can read. At the pinned openai/codex checkout That is not an argument against this code, and the description's protocol citation is appropriate. It is an argument about activation order: on the canonical ChatGPT forward route, no client we can inspect sends these frames and no captured exchange shows the backend answering them. The public API injection route in #4858 is the only leg with published documentation behind it. Keeping |

Thanks for the stack-level read. On the three points: 1. Stacked bases. Agreed in principle — but every head branch in this stack lives on my fork ( 2. Repository CI. Understood — the fork runs are the only CI available to me at these heads, and a maintainer dispatch is needed for the repository matrix. Nothing further I can do on that leg from this account. 3. Wire provenance. Conceded and consistent with the flag's posture: |

Summary
codexNativeSteeringsupport for compatible native OpenAI Responses WebSocket clients. Forwardresponse.steerinstead of silently discarding it, keeping the selected account and dedicated physical connection across accepted steering, parent termination, automatic successors and saved-tool-result continuations.response.steer.pending, optional resultname, additional user messages, approval/call identity matching and at-most-once continuations. An already dispatched continuation survives rejection of a queued steer. This implementation requires unchanged model/settings and the same lane.Protocol reference: https://developers.openai.com/api/docs/guides/steering (retrieved on 2026-09-16).
Configuration and scope
Merge these keys into the existing OpenCodex configuration and restart before a fresh turn:
{ "websockets": true, "codexNativeSteering": true }This is an experimental opt-in, not live Astra certification. A compatible client/model is still required. Acceptance means queued, not applied; disconnect/timeout can leave delivery unknown. Do not automatically rerun tools or resend accepted input. Disable
codexNativeSteeringand restart to roll back without deleting account or conversation files.Author review follow-up — 2026-09-16
Addressed both CodeRabbit correctness findings in
ce26f3ea367cba9e26745be9d70ad13c240f3a3b:RangeError.All six added cases failed before these fixes and pass afterward: the standalone steering suite changed from 21 pass / 6 fail to 27 pass / 0 fail.
Reduced duplicated architecture prose to short owner-page links to the canonical streaming-health contract, retaining each required ownership reference. Added meaningful function/method documentation for native control, replay and body-policy helpers; a new automated docstring percentage is not claimed. The file-size limit, test guards, auth/admission rules and default-off setting are unchanged.
Verification
Exact source identity
a3922b9cf3a25232f701422c5496cfd9acb78ad4— a dev-refresh merge bringing upstreamdeveca65bd350d77c407f84a10514a2ab18d711052dinto branch head76d7452afb38fd7cc5d9ff7fa4d573b06a9507e3.9e879ed2c378e9f87986a14459cadf07311a840a.dev:eca65bd350d77c407f84a10514a2ab18d711052d.69efec0d56146bc45374560f263b004c031734f9.e9621393f0cd8b02636bac82b538a7ab419fe283, with the identical source tree. The maintainer integrated current dev while testing was underway. Publication preserves that commit as parent and checks exact tree/delta equality rather than rewriting its history.Completed checks on that source tree
Each focused run covers 11 files and 2,838 assertions. The 27 native steering cases are included in the 423, not additional to that number. The single skip is the existing older-runtime HTTP fallback case on the current Bun runtime. Existing flag-off, ordinary-create and shared-transport regressions remain covered.
Evidence:
a3922b9cf(upstreamdeveca65bd35merged into the branch; feature delta re-verified unchanged at 40 files / 1,278 insertions / 33 deletions): https://github.com/luvs01/opencodex/actions/runs/35229036557 (in progress)Read the individual jobs: all validation jobs in the first run succeeded. Its original publication job correctly refused to overwrite the concurrently updated branch head. The successful second run preserves the maintainer update. An intermediate publisher also stopped on a regenerated diff-text hash check; that presentation-dependent comparison was replaced with full-index delta and exact Git-tree equality, while the immutable input patch SHA-256, expected source tree, ancestry and non-force push checks remained enforced. No application test failure was waived. The unchanged upstream Linux batch runner isolates runtime crashes; assertion failures are not ignored or retried to conceal defects.

The implementation was checked against admission/auth contracts and privacy regressions; the unchecked security box reserves independent review of the new long-lived connection/control surface.
