Summary

A second ocx instance now leaves the live proxy's shared client routing alone across startup, management requests, restart, and stop. The batch also makes Home-side Remote Link usable from the local dashboard, keeps OAuth device guidance current, and offers one-time pairing on an authenticated remote hub that lacks a GUI session.

PR Change Author
#5926 Isolate sibling startup, shared writes, restart and stop from the live owner. JUN (lidge-jun)
#5928 Admit the local Home dashboard to SSH host discovery/probe/apply, improve SSH resolution and bounded errors, and keep Child join paired-only. JUN (lidge-jun)
#5911 Show Meta Muse OAuth only to eligible GUI sessions and replace stale device hints through login. Ingwannu, with shared device-hint work credited to codingbo
#5978 Show the one-time pairing form on Remote Link for a remote hub without a GUI session. RHODIZSECURITY

The owner's three original commits retain JUN authorship. Each contributor PR remains one attributed squash commit. The older device-hint variant (#5915) is outside this branch because #5911 covers the same login behavior; its shared implementation is credited to codingbo.

Follow-up commits after independent review:

Commit Result
66967095d0 Restrict the new pairing display path to hub runtimes; a non-loopback standalone keeps its local-session guidance.
fa182b9d2d Keep sibling-home roster updates available while skipping the shared Claude Desktop profile auto-apply, including after asynchronous discovery.
32d7893113 Require a fresh, home-bound listener proof before an orphan stop can signal a discovered proxy.
dda805fbad Require a short-lived, one-use sibling restart handoff record bound to the prior sibling runtime and home; a port env alone cannot claim sibling status.
37f368cf20 Keep the connected-client sibling recycle path valid when its runtime record has no server attestation secret; the same-home PID, ports and process-local mark still gate issuance.
a42fcac751 Capture the connected sibling's one-use handoff before link recycle stops the listener and removes its runtime record; spawn with that captured environment.
d3cc7b80bb Remove the Kiro cooldown test's timestamp-order race exposed by macOS CI.

dev advanced during review. Merge commit a4d9aff73e brought in 177c647d9c and kept both the SSH PATH and listener-before-supervisor Remote Link contracts. Merge commit 43d314287c brings in current dev 93e5d5bea5 without changing the owner's commits. Their combined dashboard structure document exceeded its line budget; 1e93a8401b reflows the existing OAuth paragraph from 603 to 600 lines without raising the cap. The Kiro timing correction also landed independently on dev; the merge keeps that current test.

Screenshots from the built GUI (demo session and responses only):

Security re-review should focus on sibling start/stop and handoff (src/codex/sibling-start.ts, src/codex/sibling-handoff.ts, src/client/runtime.ts, src/cli/index.ts, src/server/proxy-liveness.ts), Desktop auto-apply (src/server/management/agent-settings-routes.ts), Remote Link admission and SSH (src/server/management/link-routes.ts, src/link/ssh-argv.ts, src/link/ssh-runner.ts), OAuth state and principal discovery (src/oauth/index.ts, src/oauth/login-flow-state.ts, src/server/management/oauth-account-routes.ts), and the hub-only pairing gate (gui/src/App.tsx). Independent reviewer sign-off remains required before merge.

Verification

  • Red/green: the clean-exit sibling stop test went from 4 pass / 1 fail (ocx stop exited 0 after discovering the owner) to 5 pass / 0 fail; the forged-env test failed with an unexpected siblingOfPort and now passes. The real handoff, wrong-home refusal and replay refusal pass. A connected-client handoff first threw for a missing server attestation secret, then passed after the issuer used its process-local mark and matching runtime record.
  • Red/green: the owned Claude Desktop route test went from 8 pass / 2 fail (one write when already marked, one after discovery) to 10 pass / 0 fail.
  • Red/green: the standalone pairing regression went from 3 pass / 1 fail (pairing form timeout) to 4 pass / 0 fail. The hub pairing case still passes.
  • Red/green after the final security review: the real connected-client link-ended supervisor test was 1 pass / 1 fail before a42fcac751, with no replacement and Cannot hand off sibling status without this home's live sibling record in the client's stderr. After capturing the handoff before cleanup, bun test tests/clients/client-link-runtime.test.ts is 2 pass / 0 fail; the test observes a healthy replacement with the same port and siblingOfPort.
  • Hosted macOS job 108450526070 at the previous head: 258 pass / 1 fail in kiro-pool-rank.test.ts; the 12-file batch now runs at the merged head with 259 pass / 0 fail.
  • At the merged head, bun x tsc --noEmit, (cd gui && bunx tsc -b), bun run lint:gui, (cd gui && bun run build), (cd docs-site && bun run build), bun run structure:check, bun run privacy:scan, and git diff --check origin/dev..HEAD all pass. The docs build generated 521 pages and checked 70,424 internal links.
  • At the merged head, focused tests pass separately: bun test tests/clients/client-link-runtime.test.ts (2), bun test tests/clients/client-runtime.test.ts (5), bun test tests/cli/cli-start-journal-order.test.ts (6), bun test tests/cli/cli-dispatch.test.ts (58), bun test tests/cli/cli-ready.test.ts (57), and bun test tests/claude-integration/claude-desktop-first-party-guards.test.ts (10); all have 0 failures. The three required layout and file-size guards pass together (27 pass / 0 fail).
  • The shared Remote Link area passes bun test tests/server/link-management-routes.test.ts tests/server/link-join-route.test.ts tests/clients/link-ssh-argv.test.ts tests/server/link-listener-lifecycle.test.ts tests/server/link-listener-admission.test.ts (62 pass / 0 fail). The three required layout and file-size guards pass together (27 pass / 0 fail).
  • Additional affected restart, client-runtime, liveness and management-route files passed individually (192 pass / 0 fail) before the dev merge. The original carry's 21 changed test files passed individually at the original head (467 pass / 0 fail). The full local suite was excluded by the batch instruction; current-head hosted CI is the remaining gate.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults. Independent re-review is pending.

Summary by CodeRabbit

  • New Features
    • Remote Link now guides users through Home-initiated setup, checks that remote machines meet the OpenCodex 2.66.0 minimum, and provides clearer troubleshooting details. Child-initiated linking is unavailable in this release.
    • OAuth login guidance updates as providers switch between device approval and manual input.
    • Eligible dashboard sessions can pair for Remote Link; provider availability reflects the current session.
  • Bug Fixes
    • Running a second proxy no longer changes shared Codex routing or disrupts the active proxy when stopped.
    • Remote SSH commands handle common PATH differences more reliably.
    • Device-code sign-in no longer displays an irrelevant callback paste field.

…ng away from the live proxy

Root cause: `ocx start --port <other>` beside a live proxy (the sibling path) ran the ordinary
startup sync and exit teardown against the CODEX_HOME, ~/.claude, ~/.grok and launchd domain it
shares with the live owner, so openai_base_url was left on the sibling's port and every Codex
thread broke once it exited.

Fix: handleStart marks the process (src/codex/sibling-start.ts) before binding. The local-client
gate, restore/inject, catalog funnel, owned-client refresh, Claude and system-env writers, client
connect, the exit and stop teardown and a management route guard (409 sibling_instance) refuse
shared writes, and the runtime record's siblingOfPort tells `ocx stop` it is stopping a sibling.
That stop claims no receipt, restores nothing and leaves the system env. Neither it nor the
sibling's own POST /api/stop asks the service manager: a sibling never runs under one, and the
installed service is the live owner's, whose ownership check used to fail the stop (or, with no
resolvable service record, let the sibling boot the owner's launchd job out). A hard-killed
sibling's stop no longer falls back to stopping the live owner: it clears the stale records and
exits 0. A sibling's drain-and-restart and standalone recycle hand OCX_SIBLING_OF_PORT to the
replacement, which honors it before any probe; every other detached `ocx start` (ensure, tray,
the claude/opencode/minimax auto-starts, the updater's and the launcher's restarts) strips it.
Archived-session cleanup, its policy run and trash restore are refused on a sibling, and the
storage policy scheduler stands down there. Translated lifecycle docs gain the sibling exception.

Security: the management guard narrows what a sibling's API can mutate in state shared with the
live owner; no new surface is opened.

…eferral oracle

The receipt-backed deferral path is unchanged; the pinned line now also skips the
service-manager probe for a sibling, whose installed service is the live owner's.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…board

Root cause: every dashboard /api/link route required a paired session, but a
standalone loopback dashboard (browser or desktop webview) only holds a
loopback-issued session, so candidates, probe, confirm-host and apply all
answered 403 and SSH hosts never loaded.

Fix: the Home-side routes (status, candidates, probe, confirm-host, apply,
DELETE) also admit the current loopback session on trusted loopback ingress of
a standalone runtime. POST /api/link/join stays paired-only; pairing sessions
exist only on hub runtimes and join requires standalone, so no dashboard can
join as a Child in this release. Status reports joinAvailable to GUI sessions
(admin-token keeps the exact K16 DTO), and the dashboard disables the Child
role with a notice in all 10 locales that points to Home-initiated linking.
Docs, structure notes and the route registry say the same.

ssh runs with Homebrew and ~/.bun/bin appended to PATH, and every remote ocx
call runs through a sh prelude that appends the fallback dirs after the remote
PATH (exit 127 -> remote_ocx_missing). confirm-host requires ocx >= 2.66.0,
parsed to a bounded semver shape. Link errors carry a bounded, redacted hint
from ssh stderr, the ssh runner's own failure, or the parsed remote version;
server and dashboard cap it at 160 code points without splitting a surrogate
pair. Specific error guidance is translated in every locale.

Security: the loopback session is minted without a credential, so this is
casual-path protection like POST /api/github/star, not a secret-backed
boundary; hubs and join keep the paired-only rule, Tailscale identity sessions
are still refused, and hints are never logged or read from stdin.

📝 Walkthrough

Walkthrough

The changes add sibling-instance isolation for shared state, revise Remote Link authorization and SSH handling, and extend management OAuth status with changing login-continuation hints. The GUI, tests, and documentation cover these behaviors.

Changes

Sibling proxy instances

Layer / File(s) Summary
Mark ownership and carry it across restarts
src/codex/sibling-start.ts, src/codex/sibling-handoff.ts, src/config/process-state.ts, src/client/runtime.ts, src/cli/index.ts, src/server/management/system-restart.ts, src/update/*, bin/ocx.mjs
Sibling instances record the live owner’s port in process state and runtime records. Replacement restarts use a one-use handoff. Detached owner starts remove inherited sibling markers.
Keep shared client state with the live owner
src/cli/dispatch.ts, src/cli/index.ts, src/codex/*, src/client/connect.ts, src/claude/agents-inject.ts, src/integrations/catalog-refresh.ts, src/server/system-env.ts, src/storage/policy-job.ts
Sibling startup, synchronization, integration, restore, and cleanup paths skip writes to shared client state.
Refuse sibling mutations and verify lifecycle paths
src/server/management-api.ts, src/server/management/sibling-guard.ts, src/server/management/config-routes.ts, src/server/stop-teardown.ts, src/lib/process-control.ts
Guarded management mutations return 409 sibling_instance. Sibling stops report sharedTeardown: "not-owned" and do not stop or tear down the live owner.

Remote Link access and SSH flow

Layer / File(s) Summary
Run remote ocx commands and capture SSH hints
src/link/ssh-argv.ts, src/link/ssh-runner.ts, src/client/link-join.ts, src/client/link-teardown.ts
Remote ocx commands use a shell PATH fallback. SSH failures produce sanitized, bounded hints.
Authorize Home routes and validate remote hosts
src/server/management/link-routes.ts, src/server/management/route-registry.ts, src/server/management/oauth-account-routes.ts, gui/src/remote-link-api.ts
Home-side routes admit qualifying dashboard sessions and paired sessions. Join remains paired-only. Host confirmation enforces OpenCodex 2.66.0 or later.
Reflect availability and errors in the dashboard
gui/src/App.tsx, gui/src/pages/RemoteLink.tsx, gui/src/i18n/*, gui/src/styles-remote-link.css, docs-site/src/content/docs/*/guides/remote-link.md
The dashboard gates Child actions on joinAvailable, displays API hints, prompts for pairing where required, and documents the Home-initiated flow.

OAuth login continuations

Layer / File(s) Summary
Store and expose current OAuth hints
src/oauth/login-flow-state.ts, src/oauth/index.ts, src/server/management/oauth-account-routes.ts
Active OAuth status exposes the current URL, device code, and instructions. New callbacks replace prior hints, and completed or cancelled flows clear them. Management discovery filters Meta Muse by principal.
Update login UI and validate polling behavior
gui/src/components/login-url-block.tsx, gui/src/components/use-add-provider-oauth.ts, gui/src/pages/providers-shared.ts, gui/src/pages/use-providers-oauth.ts
The GUI hides callback paste for device codes, replaces displayed login details from status hints, and clears continuation details when the flow completes.

Merge Risk: 🟡 Moderate · up to 1e93a

Stopping a sibling can terminate another running OpenCodeX instance under a stale-PID reuse condition. Fix that stop path before merging; clarify the sibling documentation as well.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 1e93a

The new sibling-ownership controls appear to protect the live proxy and its client routing, but the change spans several lifecycle and access boundaries. Some failure and authorization paths remain insufficiently verified to rate the design as minimal risk.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — A mistaken local ownership decision could affect the home’s proxy records and shared Codex or Grok client routing, rather than granting demonstrated cross-tenant or remote privilege. The reviewed handoff is local to a process environment and home-specific record.

Security Findings and Attack Paths

  • observed — No retained Security finding is supplied. Inconclusive discovery remains a potential route to local shared-state recovery without proof of absence, but the same inspected handling exists in the immediate parent; whether this PR worsens its effective exposure is unresolved.

Trust Boundaries and Controls

  • observed — Sibling-marker environment fields are removed before validation. Handoff consumption atomically claims the record and checks its nonce, canonical home, owner port, file restrictions, and age before deleting it; explicit failed live-proxy ownership proof blocks orphan stop.

Resilience and Maintainability Implications

  • observed — Sibling stop avoids service-manager action and shared restore, and uncertain CLI ownership publication retains its lease. These controls limit damage from interruption, though full cleanup following a partially failed machine-listener creation remains unverified.

Hardening Proposals

  • proposed — Distinguish definitively absent proxies from inconclusive discovery before deleting ownership records or restoring shared client routing, and verify the Remote Link server authorization path independently of dashboard visibility.

이 PR은 네 가지 수정을 한 브랜치 codex/bug-train-9d에 모아 dev로 넣으려 한다. 헤드는 78e47d8이고, 아직 열려 있다. 베이스는 dev가 맞다.

이미 켜져 있는 ocx 옆에 ocx start --port <다른 포트>로 두 번째 프로세스를 띄우면, 그 프로세스가 Codex, Grok, Claude 설정과 macOS 로그인 항목을 같이 고쳐 버렸다. 두 번째가 꺼지면 살아 있는 프록시의 주소가 깨졌다. 이제는 시작하자마자 "동생 인스턴스" 표시를 하고, 그 표시가 있는 동안은 공유 파일을 쓰지 않는다. 관리 화면의 공유 쓰기 주소는 409 sibling_instance로 거절한다. ocx stop도 그 표시를 보고, 살아 있는 주인의 서비스를 끄지 않는다. 동생이 자기 자신을 재시작할 때만 OCX_SIBLING_OF_PORT를 다음 프로세스에 넘긴다.

로컬 대시보드의 Remote Link는 SSH 컴퓨터를 못 불러왔다. 페어링된 화면 세션만 통과했는데, 혼자 도는 루프백 대시보드에는 그 세션이 없다. 이제는 혼자 도는 런타임에서, 루프백이 방금 만든 현재 세션이고, 그 요청이 신뢰하는 루프백으로 들어왔으면 홈 쪽을 연다. 홈 쪽은 후보 목록, 접속 시험, 호스트 키 저장, 연결(apply), 끊기다. 이 컴퓨터를 Child로 붙이는 POST /api/link/join은 페어링 세션만 받는다. 혼자 도는 런타임은 그 세션을 만들지 않으므로, 이번 버전 대시보드에서는 Child 가입이 막혀 있고 안내 문구가 나온다.

Meta Muse 로그인 화면은 기기 코드와 다음 단계 안내가 중간에 바뀌면 옛 내용을 남겨 두었다. 이제는 로그인 상태에 힌트를 넣고, 화면이 상태를 다시 읽을 때 최신 안내를 보여 준다. 단계가 바뀌면 이전 코드를 지우고 새 힌트로 갈아끼운다. 공급자 목록은 화면 세션이 아니면 Meta Muse를 숨긴다. 로그인을 시작하는 POST는 화면 세션만 통과한다.

화면 세션이 없는 원격 허브에서 Remote Link를 열면, 막다른 로그인 경고 대신 기존 일회용 페어링 폼이 나온다. 다른 페이지의 관리자 토큰 입력은 그대로다.

원격의 ocx는 sh -c로 PATH에 bun과 Homebrew 자리를 덧붙인 뒤 실행한다. ssh가 실패하면 마지막 오류 한 줄을 160자 안으로 잘라 대시보드에 보여 준다. ocx_data_ 같은 토큰과 주소의 쿼리는 지운다. 바뀐 테스트는 467개 통과, 가드 테스트는 27개 통과라고 본문에 적혀 있다. 전체 테스트는 일부러 돌리지 않았고 CI에 맡긴다. 보안 검토 체크는 아직 비어 있다.

src/oauth/index.ts:1798 - 로그인이 끝나기 전에 getLoginStatus가 hint로 주소, 안내 문장, deviceCode를 상태 응답에 넣는다.
src/server/management/oauth-account-routes.ts:315 - GET /api/oauth/status는 canStartManagementOAuth(189행)를 보지 않는다. Meta Muse 시작은 화면 세션만 되는데, 그 세션이 로그인을 연 뒤 관리자 토큰으로 상태만 읽어도 기기 코드가 나온다. 동의 검사는 시작 POST에만 있고, 이번에 상태 응답에 붙은 힌트에는 없다.

src/server/management/link-routes.ts:102 - dashboardSession이 페어링 세션 옆에, 혼자 도는 런타임의 현재 루프백 세션도 홈 링크로 들인다. 후보, 프로브, 호스트 확인, apply(574–589행)와 링크 삭제가 이 세션으로 열린다. apply는 데이터 키를 만들어 SSH로 원격에 보낸다. 루프백은 비밀번호 없이 세션을 만든다. 그 포트에 닿는 로컬 프로세스가 홈 링크를 걸 수 있다. 코드는 PR 본문이 적은 설계와 같고, 테스트도 그 경계를 고정한다. 이 개방을 받을지는 아래 판단이다.

메인테이너의 판단이 필요한 지점

  • 루프백 대시보드 세션에 홈 링크 apply(키 발급과 터널)를 열어도 되는지. Child 가입은 이번 릴리스에서 닫아 둔 채로 갈지.
  • GET /api/oauth/status의 힌트를, 그 공급자 로그인을 시작할 수 있는 호출자에게만 줄지.
  • 체크리스트의 보안 서명은 따로 필요하다. 이 댓글만으로 그 칸을 채우면 안 된다.
  • 전체 테스트를 로컬에서 돌리지 않은 것을 CI가 초록이 된 것으로 받아도 되는지.

너의 추천
상태 힌트는 그 로그인을 시작할 수 있는 호출자에게만 내려 주고 머지하는 쪽이 맞다. Meta Muse는 화면 세션이다. 루프백 홈 링크는 로컬 대시보드를 고치려면 필요하고, Child 가입을 페어링 세션 전용으로 둔 절단은 유지하면 된다. 베이스는 이미 dev다. 이 배치를 살리면 아직 열려 있는 #5926, #5928, #5911, #5978은 같은 내용이라 닫고, #5915는 #5911이 같은 로그인 동작을 이미 다루므로 무효인 중복으로 닫으면 된다.

P2 Badge Show pairing only for runtimes that can issue grants

When a standalone proxy is deliberately bound to a non-loopback address, adminTokenPromptAllowed() returns true from the management-auth meta tag, so this condition replaces Remote Link with ConnectPairingForm. However, src/cli/gui.ts:25-28 and the server grant implementation reject pairing unless runtimeRole === "hub"; therefore the displayed ocx gui pair command can never succeed and the standalone Remote Link page remains inaccessible. Gate this form on a pair-capable hub/connected target, or preserve an authentication path that standalone runtimes can complete.

Prevent a sibling stop from trusting a reused PID.

readPid() accepts any live ocx start process with the recorded PID. It does not verify that the process belongs to the current OPENCODEX_HOME. A reused PID can therefore enter the tracked branch before siblingStopFoundOwner() runs. If the sibling endpoint is gone, stopProxy() falls back to killProxy(pid), which can terminate the owner process from another home.

Extend the PID identity check to include home ownership, or otherwise prevent sibling records from entering the tracked-PID stop path unless the process belongs to the sibling's home.

Correct the sibling sentence.

A sibling skips startup sync and does not restore native Codex. The sibling still performs a data-plane auth.json refresh, so “neither syncs” is broader than the code supports.

Proposed wording
-a sibling instance beside a live proxy ([Codex home](codex-home.md#codex-home)) syncs and restores nothing,
+a sibling instance beside a live proxy ([Codex home](codex-home.md#codex-home)) skips startup sync and does not restore native Codex,
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

A non-loopback standalone dashboard still needs a GUI session, but it cannot complete the hub pairing flow. Keep the new pairing branch scoped to hub runtimes.
Keep the sibling home roster writable while preventing its management route from rewriting the owner Desktop profile. Check again after discovery and transition awaits.
A clean sibling exit removes its runtime record, so configured-port discovery can find the live owner. Require a fresh proof against this home’s runtime secret before stopping a discovered PID; refuse shared teardown without that proof.
A port environment variable alone cannot mark a direct source launch as a sibling. Issue a short-lived handoff only from the live sibling record in the same home, then atomically consume it before the replacement probes ownership.
The macOS shard crossed a millisecond between captured now and the seed write. The evidence timestamp was then in the future and the test correctly read no verdict. Capture evaluation time after seeding and derive the exact reset interval.
Keep the current dev Kiro cooldown regression and combine both Remote Link structure contracts: the 9D SSH PATH behavior and the 9C listener-before-supervisor ordering.
A connected-client runtime has no server attestation secret in its home record. The one-use issuer already requires the process-local sibling mark and the matching same-home runtime PID, own port and owner port; allow that legitimate recycle path.

cleanup() runs before issueSiblingHandoff, so a sibling recycle always throws.

In recycleStandalone, Line 72 calls cleanup() before the spawn. cleanup() calls removeRuntimePort(process.pid), which deletes runtime-port.json. After that, Line 96 evaluates withSiblingMarker(..., issueSiblingHandoff). issueSiblingHandoff calls readRuntimePort(process.pid) (sibling-handoff.ts Line 23), gets null, and throws "Cannot hand off sibling status without this home's live sibling record.".

The exception escapes recycleStandalone before process.exit(0). For a sibling, the unsupervised recycle therefore never spawns a replacement, and the process is left with its listener already stopped. The test a sibling client runtime can hand off without a server attestation secret in tests/cli/cli-dispatch.test.ts Line 684-702 writes the record first, so it does not cover this ordering.

To fix this, build the child env before cleanup():

Proposed fix
   activeSupervisor = null;
+  const childEnv = port && process.env.OCX_SERVICE !== "1"
+    ? withSiblingMarker(standaloneRecycleEnv(process.env, disconnectedTokenFingerprint), issueSiblingHandoff)
+    : undefined;
   try {
     activeServer?.stop(true);
 ...
-      env: withSiblingMarker(standaloneRecycleEnv(process.env, disconnectedTokenFingerprint), issueSiblingHandoff),
+      env: childEnv,

Confirm by inspecting the order of statements in recycleStandalone.
