Summary

Merge train round 3, batch 8: four bug fixes that opened during this round, each carried as one squashed commit that keeps its author. Batches 1 to 7 landed as #6059, #6061, #6062, #6063, #6066, #6069 and #6070.

PR Change Author
#6064 A Remote Link enrollment now has one outcome. A tunnel exit aborts the connection transaction's real requests, readiness polling notices an exit while it sleeps, an exit after commit keeps the committed key, and an exit before commit finishes local rollback before revoking the key. luvs01
#6068 The Child relay authenticates and streams on one socket. A credential-free challenge proves the link identity with a one-use, direction-tagged proof. The data request must reuse that socket, and a peer without the protocol is refused, never retried without authentication. Pending rotation keys are accepted. This replaces the closed #6044. luvs01
#6067 The web-search probe lease is held until an error response's body settles, instead of being released on the status code as soon as the error returns (follow-up to #6047). luvs01
#6065 On Windows, ocx doctor and Claude Desktop status report when the system proxy makes Desktop's Code tab bypass first-party routing. WPAD, a stale env, and absent versus unreadable registry values are kept distinct. kaladinhonor

Integration: the tail of structure/remote-link.md keeps both #6064's enrollment paragraph and #6068's relay section. The two new test registrations share one layout line, so scripts/test-layout/layout.json is at 1994 lines.

Summary by CodeRabbit

  • New Features
    • Remote links now authenticate each relayed request over the same connection, helping prevent unauthorized or replayed requests.
    • On Windows, ocx doctor can report when Claude Desktop’s first-party routing may conflict with system proxy settings, without exposing proxy values or failing the check.
  • Bug Fixes
    • Link enrollment now handles tunnel exits more reliably, avoiding delays and preserving completed connections.
    • Web-search probe handling now remains active until streamed responses finish or are cancelled.
  • Documentation
    • Added guidance for Windows proxy troubleshooting and remote-link authentication compatibility.

📝 Walkthrough

Walkthrough

This pull request adds same-socket authentication for linked-machine relay requests and enrollment cancellation on tunnel exit. It also adds Windows Claude Desktop proxy diagnostics, adjusts Responses sidecar probe lease handling, updates related documentation and tests, and records merge-train evidence.

Changes

Connection-Bound Link Relay

Layer / File(s) Summary
Relay proof validation and listener sessions
src/link/relay-auth.ts, src/server/index/link-relay-sessions.ts, src/server/index/link-listener.ts, src/server/index/optional-listeners.ts, tests/clients/link-relay-bound-transport.test.ts
Adds direction- and identity-bound proofs, one-use listener reservations, and active-response tracking. Listener shutdown aborts reservations; normal closure drains active work.
Client transport and relay integration
src/client/link-relay-transport.ts, src/client/link-relay.ts, src/client/link-ingress.ts, src/client/machine-listener.ts, tests/clients/client-link-relay.test.ts, tests/clients/link-relay-bound-transport.test.ts, docs-site/src/content/docs/guides/remote-link.md, structure/remote-link.md, structure/runtime.md, structure/clients/claude-desktop.md, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json
The client sends the challenge and relayed request on the same socket. Link and API-key IDs reach the transport, which rejects authentication failures without an ordinary-fetch fallback. Tests and docs describe the authenticated relay path.
Enrollment cancellation and commit boundary
src/client/connect.ts, src/client/link-join.ts, tests/clients/client-link-connect.test.ts, tests/server/link-join-route.test.ts, structure/remote-link.md
Enrollment network work and subsequent writes observe cancellation. Tunnel exit before commit aborts enrollment and completes rollback; exit after commit preserves the link. Tests cover readiness, rollback, and commit-boundary cases.

Claude Desktop Windows Proxy Diagnostics

Layer / File(s) Summary
Windows proxy registry reading and matching
src/lib/windows-system-proxy.ts, tests/claude-integration/claude-desktop-system-proxy.test.ts
Adds diagnostic-only readers for Windows proxy bypass, PAC, and auto-detect settings. HTTPS bypass matching handles supported patterns, schemes, and ports.
Desktop proxy assessment and doctor output
src/claude/desktop-system-proxy.ts, src/cli/doctor.ts, tests/claude-integration/claude-desktop-system-proxy.test.ts, docs-site/src/content/docs/guides/claude-code.md, structure/clients/claude-desktop.md, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json
Classifies whether Windows proxy settings cover or bypass api.anthropic.com. Applicable results are printed by ocx doctor without exposing proxy values or failing the command. Tests and docs cover diagnostic states and remediation.

Responses Sidecar Probe Leases

Layer / File(s) Summary
Probe lease settlement and response tests
src/server/responses/sidecar-execution.ts, src/server/responses/core.ts, tests/responses/responses-run-turn-web-search.test.ts, structure/transports/responses.md
Local validation errors release the search probe lease. Streamed responses retain the lease until completion, cancellation, or error, regardless of HTTP status.

Merge Risk: 🟡 Moderate · up to 37d06

After the last Home link is removed, the listener waits indefinitely for active relayed streams to finish. A removed link can therefore keep streaming, and a newly added link cannot bind until the old stream ends. Add a bounded drain deadline before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 37d06

The relay adds a connection-bound identity check, and the reviewed enrollment path preserves its commit boundary. No introduced security flaw was established, but incomplete coverage and an unresolved key-issuance recovery case prevent a minimal-risk assessment.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The independently attackable relay surface is the Home link listener. A successful proof is limited to its configured link and key identity and the reserved peer socket; ordinary requests remain subject to hub-link admission.

Trust Boundaries and Controls

  • observed — The challenge carries no API-key header, uses direction-separated proofs, and cannot authorize a later request from a different peer or after its fingerprint ceases to be configured.

Resilience and Maintainability Implications

  • observed — Known hub-issued keys are revoked on enrollment failure. The client learns a new key ID only after reading and parsing the issuance response, leaving interrupted-response cleanup dependent on server behavior that was not established.

Hardening Proposals

  • proposed — Establish an idempotency or orphan-cleanup contract for hub key issuance so interruption after server-side creation cannot leave an untracked credential.

:::note[Windows system proxy (Clash, v2rayN, corporate proxies)]
When a Windows system proxy is on, Claude Desktop hands it to the Code tab as `HTTPS_PROXY`, and
that value takes precedence over the OpenCodex proxy in `~/.claude/settings.json`. The Code tab
then goes around OpenCodex and routed models fail there, while the standalone CLI keeps working.
Add `api.anthropic.com` to your proxy client's system-proxy bypass list (in Clash Verge,
`system_proxy_bypass`), then fully quit and reopen Claude Desktop. `ocx doctor` reports this
under "Claude Desktop first-party vs Windows system proxy". It cannot evaluate a PAC script or
automatic proxy detection (WPAD, "Automatically detect settings"), so it reports those as unknown;
with either, make the script return `DIRECT` for `api.anthropic.com` or turn detection off. If the
first-party settings are stale, it asks you to run `ocx ensure` instead of reporting `ok`.

Update the translated Claude Code guides.

The new Windows system proxy guidance appears only in the English guide. Add an equivalent note to:

  • docs-site/src/content/docs/ja/guides/claude-code.md
  • docs-site/src/content/docs/ko/guides/claude-code.md
  • docs-site/src/content/docs/ru/guides/claude-code.md
  • docs-site/src/content/docs/zh-cn/guides/claude-code.md

If translation is pending, mark the section accordingly. Otherwise, users of these locales will not see the documented api.anthropic.com bypass, restart step, or ocx doctor limitations.

### Relay authentication compatibility

Update both the Home and Child when upgrading to connection-bound relay authentication. Before sending a relayed request's link credential or body, the Child verifies the Home on the same connection it will use for that request. A closed connection is not silently replaced. A Home without this protocol causes a retryable authentication error; upgrade the Home and Child, and re-link when the stored link is no longer recognized. There is no insecure fallback switch. An unexpired pending API-key rotation remains valid until it expires or the rotation is committed or aborted.

Removing the final Home link drains pending authenticated relay requests before releasing its listener. Stopping the process still cancels active connections. This does not change which caller credentials are stripped or which routes can be relayed, and it does not replace SSH's host-key verification.

Move "Relay authentication compatibility" out of the "Related guides" section.

The new ### heading comes after the ## Related guides link list (Lines 87-90). Starlight therefore renders the upgrade guidance as a subsection of "Related guides", and the page table of contents lists it there. This guidance describes an upgrade requirement for both machines, so a reader who scans the setup and upgrade sections will not find it.

Fix: make it a ## section and place it before ## Related guides. The path instructions also require that the ja, ko, ru and zh-cn pages stay consistent with the English source. Add the same section to those pages, or note that they are pending translation.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Setting redirect: "manual" unconditionally changes behavior only when a signal is present.

The fetchImpl wrapper forces redirect: "manual" whenever deps.signal is set. Without a signal, rawFetch receives the caller's own redirect value. As a result, hub-mode connectClient calls follow a different redirect policy depending on whether the caller passes a signal. fetchHubReady, exchangeConnectPairingGrant, issueClientKey and downloadClientCatalog all run through this wrapper. If any of these helpers depends on following a redirect, it fails only when a signal is present.

Refusing redirects is a sensible hardening step because key-bearing requests should not follow redirects. Apply it in both branches so that behavior does not depend on the signal.

Proposed fix
-  const fetchImpl: typeof fetch = deps.signal ? Object.assign(async (...[input, init = {}]: Parameters<typeof fetch>) => {
-    deps.signal!.throwIfAborted();
-    const signals = [deps.signal, init.signal, input instanceof Request ? input.signal : undefined]
-      .filter((signal): signal is AbortSignal => signal != null);
-    return rawFetch(input, { ...init, signal: AbortSignal.any(signals), redirect: "manual" });

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

close() now waits with no time limit for active response bodies. The revoked link keeps streaming, and rebinding is blocked.

What changed: close() awaits relaySessions?.drain() and then current.stop(false). It no longer calls stop(true).

Why the wait is unbounded:

  • drain() resolves only when active === 0.
  • Every dispatched response holds a lease until its body reaches EOF, errors, or is cancelled. This includes legacy requests without a nonce (link-relay-sessions.ts Line 99).
  • The Home listener lifts idle timers, and relayed SSE turns can run for a long time. A continuously streaming response can therefore keep close() pending for minutes or hours.

Consequences:

  1. Revocation does not take effect. Link removal is a revocation. After the last link is removed (the test at tests/clients/link-relay-bound-transport.test.ts Line 138), the removed link's response keeps streaming Home-served content with no time limit.
  2. New links cannot bind. ensureStarted() awaits closeFlight at Line 154. If an operator adds a link while the drain is pending, the bind waits until the old stream ends. structure/remote-link.md Line 47 says that a listener that is not listening fails the apply. Link apply therefore stalls or fails for an unbounded period.

Fix: add a drain deadline. After the deadline, retire reservations and force-stop the listener.

🐛 Proposed fix
       if (current) {
-        await relaySessions?.drain();
-        await current.stop(false);
+        const sessions = relaySessions;
+        let timer: ReturnType<typeof setTimeout> | undefined;
+        const drained = await Promise.race([
+          (sessions?.drain() ?? Promise.resolve()).then(() => true),
+          new Promise<false>(resolve => { timer = setTimeout(() => resolve(false), LINK_LISTENER_CLOSE_DRAIN_MS); }),
+        ]);
+        clearTimeout(timer);
+        if (!drained) {

+        } else {
+          await current.stop(false);
+        }
       }

Define LINK_LISTENER_CLOSE_DRAIN_MS (for example 30 000 ms). Add a regression test in tests/clients/link-relay-bound-transport.test.ts: close the listener during an unending stream and assert that close() settles after the deadline.

📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

The drain-lease test does not prove that the lease blocks drain.

At Line 161, expect(done).toBe(false) runs synchronously right after book.drain().then(...). A .then callback never runs synchronously, so this assertion passes even when drain() resolves at once. The test also never checks that the drain lasts about reservationMs.

Fix: sleep for less than the lease, assert that the drain is still pending, then await it.

P2 Badge Treat bypassed static proxies with WPAD as undecidable

When automatic proxy detection is enabled or unreadable alongside a static proxy whose bypass list contains api.anthropic.com, this branch still returns bypassed, so formatDesktopSystemProxyLines begins with ok even though WPAD may select a different proxy for the host. This contradicts the changed guide's promise that WPAD is reported as unknown and can falsely reassure users whose Code tab still bypasses OpenCodex. Return an undecidable verdict whenever autoDetect !== false, retaining the static bypass only as explanatory context.

P2 Badge Honor the PAC enable flag before reporting a script

On Windows, AutoConfigURL can remain populated while the setup script is disabled; whether it is active is represented by the 0x04 flag in the same DefaultConnectionSettings blob currently parsed only for WPAD. Returning every nonempty URL here makes classify immediately report pac, hiding the actual static or no-proxy verdict for configured-but-disabled scripts. Parse the auto-proxy-URL flag alongside 0x08 and expose the URL only when that flag is enabled.

이 PR은 머지 열차 3라운드의 여덟 번째 묶음이에요. 바탕은 dev예요. 열린 버그 네 개를 커밋 하나씩 가져와요. #6064, #6068, #6067, #6065예요.

집 링크에 이 컴퓨터를 등록할 때, 터널이 끊긴 일과 등록이 끝난 일이 서로 이기지 않아요. 연결을 적어 둔 뒤에 터널이 끊기면 열쇠를 남겨요. 적기 전에 끊기면, 이 컴퓨터에 적어 둔 목록과 열쇠를 지운 다음 원격 열쇠를 지워요. 집이 준비됐는지 보는 동안 터널이 끊기면, 남은 대기 시간을 다 기다리지 않고 바로 실패해요. 등록이 평범한 오류로 끝날 때 터널을 끄면서 종료가 올라와도, 오류 이름은 join_connect_failed로 남아요. 되돌리기 전에 취소 표시를 고정해 둔 결과예요.

자식이 집으로 데이터를 넘길 때는, 확인에 성공한 그 연결로만 열쇠와 본문을 보내요. 확인 요청에는 열쇠가 없어요. 한 번만 쓰는 숫자와, 부르는 쪽과 듣는 쪽이 다른 서명이에요. 그 연결이 닫히면 다른 소켓으로 다시 보내지 않아요. 이 확인을 모르는 집은 503을 받아요. 아직 만료되지 않은 대기 열쇠도 통과해요. 마지막 링크를 지우면, 이미 받은 응답이 끝날 때까지 포트를 붙잡아요. 프로세스를 끌 때는 그 응답을 끊어요.

검색에 쓰는 OpenAI 계정은 쿨다운에서 깨어날 자리를 하나만 가져요. 실패 응답의 상태 코드만 보고 그 자리를 바로 놓지 않아요. 본문이 있으면, 본문이 끝나거나 읽다 실패하거나 손님이 끊을 때 놓아요. 도구 결과의 call_id가 비었거나, 이미지 브리지인데 스트림이 아니면, 업스트림 본문이 없으니 그 자리에서 놓아요.

Windows에서 시스템 프록시가 Claude Desktop 코드 탭을 OpenCodex 밖으로 보내면, ocx doctor가 알려 줘요. 프록시 주소는 화면에 안 나와요. PAC 스크립트와 자동 검색(WPAD)은 알 수 없다고 해요. 레지스트리를 못 읽은 것과 값이 없는 것을 나눠요. 설정 파일의 프록시가 오래됐으면 정상이라고 하지 않아요. 이 항목은 doctor 실패 횟수에 안 들어가요. 단독 CLI와 다른 클라이언트는 계속 OpenCodex로 가기 때문이에요.

structure/remote-link.md 끝에는 등록 문단과 중계 확인 절이 둘 다 있어요. 새 테스트 두 개는 배치 표에서 한 줄에 붙었어요. types.ts와 config.ts를 나누는 작업과는 안 겹쳐요.

라인 - tests/responses/responses-run-turn-web-search.test.ts 331행. 75행에서 runWithWebSearch를 바꿔, 본문을 아직 안 읽은 503 스트림을 그대로 돌려줘요. 실제 검색 루프는 첫 실패에서 업스트림 본문을 읽은 뒤 짧은 JSON으로 바꿔요 (src/web-search/loop.ts 843행). 이 테스트가 통과해도, 진짜 첫 실패가 회복 자리를 언제 놓는지는 안 보여요.

라인 - src/link/relay-auth.ts 14행. 서명의 열쇠는 데이터 열쇠 원문이 아니라 그 열쇠의 SHA-256이에요. 그 해시는 클라이언트 설정의 tokenFingerprint와 같아요. 같은 계정이 그 설정을 읽으면 확인 답을 만들 수 있고, 바로 다음 데이터 요청에서 열쇠 원문을 받아요.

메인테이너의 판단이 필요한 지점

옛 자식을 언제까지 받을지 정하면 돼요. src/server/index/link-relay-sessions.ts 96행은 세션 헤더가 없는 요청을 예전 열쇠 확인으로 넘겨요. 집을 먼저 올려도, 옛 자식은 포트를 차지한 프로세스에 열쇠를 보내요. 그 길을 집에서 막아도 열쇠는 이미 나가요. 자식을 같이 올려야 포트 가로채기가 닫혀요.

같은 계정까지 막을지는 다음 수정으로 정하면 돼요. 이 묶음은 포트가 바뀌는 경우만 막아요.

충돌 표시(!!)를 doctor 실패로 셀지는 경고로 두면 돼요. CLI와 다른 클라이언트는 그대로 돌아요.

너의 추천

네 수정을 이 묶음으로 머지하세요. 바탕은 dev로 두세요. 머지한 뒤 #6064, #6068, #6067, #6065는 닫으세요. 같은 변경이 한 번 더 들어가지 않게 해요. 검색 쪽은 루프가 실제로 돌려주는 짧은 JSON으로 자리 놓기를 한 번 더 잠그면 좋아요. types.ts / config.ts 분할은 이 묶음과 다른 일이라 그대로 두세요.
