Split the app-server shim out of #5947. ocx chatgpt launch|restore|status relaunches ChatGPT with CODEX_CLI_PATH pointing at a generated launcher that execs the bundled codex app-server unchanged and pipes only its stdout through the hidden 'ocx internal chatgpt-app-server-filter'. The filter clears the plain-quota gate in account/rateLimits/read and account/rateLimits/updated and passes every other line through byte for byte. The launcher falls back to the untouched binary when the platform check, runtime or filter self-test fails. Default off behind chatgptDesktop.appServerShim; macOS only; experimental.

…5947) Stacked on the app-server shim. Adds the experimental, default-off chatgptDesktop.unblockSend mode: a loopback TLS listener with a locally issued CA terminates chatgpt.com traffic from the ChatGPT desktop app, relays HTTP and WebSocket traffic upstream through the configured proxy, and clears the plain-quota send gate using the shim's gate-rewrite helpers. The SOCKS5 handshake moves to src/lib/socks5-handshake.ts and is shared with the fetch tunnel. The PAC fallback is left for the next stacked PR. Two fixes on top of #5947: an http:// proxy without an explicit port now dials 80 instead of 8080, and a proxy that closes mid-handshake fails the upstream dial instead of hanging the upgrade.

Merge Risk: 🔵 Low · up to Both features are opt-in and off by default. With the intercept enabled, voice and dictation may ignore NO_PROXY settings. An invalid chatgptDesktop config block is silently ignored instead of reported. The guide's evidence paragraph presents an older result as current. These are bounded follow-ups. The decision to approve installing the CA remains with the project owner. Security Architecture ReviewSecurity architecture risk: 🟠 High · up to Enabling this experiment exposes signed-in ChatGPT traffic to a local relay and asks you to trust a certificate authority whose authority extends beyond ChatGPT. That trust remains after restoring normal networking. Manual activation and protected key files reduce exposure, but compromise of the signing key could affect other TLS traffic trusted by the same user. Retained concerns

There was a problem hiding this comment.
When HTTPS_PROXY or ALL_PROXY is configured together with NO_PROXY=chatgpt.com, this path still selects the proxy because effectiveProxyFor deliberately does not apply noProxyMatches; the normal provider transport performs that additional check in src/lib/provider-outbound.ts. Consequently, intercepted voice and dictation traffic—including account cookies—travels through a proxy the operator explicitly excluded, or fails if that proxy cannot reach ChatGPT. Apply noProxyMatches before choosing the proxy, while preserving explicit test overrides.

If a launch or watcher process is killed while holding this lock, every subsequent watcher run silently exits and explicit ocx chatgpt launch reports another launch in progress. The cleanup cannot recover on the only supported platform because macOS's BSD find does not provide the GNU -maxdepth primary (see the macOS find(1) manual); stderr is discarded, so the failure is invisible. Replace this command with a macOS-compatible age check/removal.

If the upstream keeps sending bytes without the terminating blank line, this loop repeatedly concatenates the entire response and has no size ceiling; the timeout limits duration but not memory, so a fast malformed endpoint can allocate enough memory to terminate the proxy. The pre-TLS HTTP CONNECT reader has the same unbounded accumulation in ProxyHandshakeReader.feed. Enforce a response-head limit, analogous to the existing 64 KiB HTTP response limit, and abort the tunnel once it is exceeded.

When an upstream or intermediary returns any 101 response—even with a missing or incorrect Sec-WebSocket-Accept—the relay upgrades the app-side socket and starts parsing subsequent bytes as frames. Because this method generated the upstream key, it must verify the corresponding SHA-1 accept value (and required upgrade headers) before reporting success; otherwise a malformed or misrouted upgrade appears connected and then stalls or corrupts the relay.

New field evidence in #6196 needs to be reflected in this description before the owner decision: TooSpace now reports a no-shim Group A on the same Desktop build, with bundled-or-dev app-server launches, zero shim-script occurrences, usable Send, and Chromium network-service connections to the local intercept. Therefore the earlier zero-established-connections result is historical, not a valid blanket statement that the intercept is never active or that #6361 is the measured active mechanism. This is a local port and GUI-activation observation, not proof of a submitted routed turn, necessity, or general efficacy; I asked for clarification of the saved 0%-window convention only, not another account trial.\n\nSeparately, current-head CI 36835306658 is not green: test 3/4 job 110281262713 fails tests/clients/client-link-runtime.test.ts:151 after the replacement-runtime ready record, with ConnectionRefused fetching /healthz. It does not establish a defect in this intercept, nor a harmless baseline flake without a controlled comparison. Please diagnose whether the child exited/listener stopped or readiness/port ownership raced; preserve cleanup and assertions, and provide a justified baseline comparison if classifying it as unrelated. No local scan or live CA/Keychain/app restart was performed. The open #6361 stack is valid; CA trust and account-relay approval are still owner decisions. |

Update the evidence paragraph so it does not present the 20-hour zero-connection result as current.
Lines 173-176 say that #6196 "reported zero established listener connections over about 20 hours on current Desktop builds". They also say the bundled app-server "may bypass Chromium's resolver rule".
Later evidence on #6196, quoted in the PR discussion, shows a different picture. A no-shim run on the same Desktop build had a usable Send button. It also showed Chromium network-service connections to the local intercept. The reviewer called the earlier zero-connection result historical. The reviewer also noted that port and GUI observations do not prove a routed turn was submitted, or that the intercept was necessary.
The path instruction for docs-site/** says user-facing docs must "stay in sync with actual CLI/API behavior". This guide is the only page a user reads before installing a trusted root CA. It currently gives an outdated and stronger negative claim than the evidence supports.
Reword the paragraph to describe both observations and their limits:

Honor NO_PROXY for the raw WebSocket dial.
effectiveProxyFor selects HTTPS_PROXY without calling noProxyMatches. Therefore, when NO_PROXY or no_proxy includes chatgpt.com, the HTTP relay can connect directly while the WebSocket relay still uses the proxy. Voice and dictation can fail even though text requests work.

Warn when chatgptDesktop is discarded.
configSchema converts an invalid chatgptDesktop block to undefined. The diagnostics only check valid flags enabled on non-macOS platforms, so malformed blocks are silent. warnDegradedTopLevelOptIns also does not check this block, although loadConfig calls it on all load paths.

The launch watcher's launchd agent wakes on the app's SingletonLock and on a readiness marker (`chatgpt-unblock.ready`) that `startChatgptUnblock` rewrites once the listener is up, so an app that opened at login before opencodex is routed as soon as the listener answers. In watch mode it only restarts an app that started within the last five minutes (`ps -o etime=`): the marker also fires when opencodex restarts under an app the user has been working in, and that one must be left alone. An unreadable age counts as a fresh launch; `ocx chatgpt launch` always acts. Carried over from the split, and kept: app lookup by `pgrep -a -x ChatGPT` (without `-a`, pgrep skips its own ancestors), `bash -n` on the generated script before launchd loads it, and the shim env passing through the shared launch script. The guide's watcher paragraph is updated in all eight locales.
Brings the branch to the current dev tip. The resolution matches replaying lidge-jun#6365's intercept commits and the watcher commits onto dev without the pre-squash shim commit, whose content dev already carries through lidge-jun#6361 and lidge-jun#6412: - `src/cli/chatgpt-command.ts` keeps lidge-jun#6365's intercept subcommands and adopts dev's shim hardening: bundle discovery by com.openai.codex, the OpenAI-signed bundle check before the launcher is written, this user's processes only, quit by bundle id, reopen by bundle path. - The structure doc keeps dev's bundle-trust paragraph; runtime.md keeps dev's line with the lifecycle sentence folded in, within its 600-line budget. - Test layout maps both dev's new files and the intercept's test files.

@lidge-jun CodeRabbit raised two findings on #6381 that are about the intercept code from this PR, so I'm leaving them to you here instead of changing the intercept in #6381:
Separately, for bringing this branch up to |
The app-server shim reached dev through lidge-jun#6361 and the send-unblock intercept is now lidge-jun#6365, with the ready-marker watcher on top in lidge-jun#6381. This branch takes that tree (dev included) and adds the one part that is still only here: PAC fallback. - entry-proxy.ts and pac.ts as before; runtime.ts binds the CONNECT entry and rewrites chatgpt-unblock.pac at every start, before the readiness marker, and releases both listeners on failure. - The launch watcher gains the PAC switch, the entry probe and PAC-aware restore on top of lidge-jun#6381's script; ocx chatgpt launch, install-watcher and status pass and report the entry port. - chatgptDesktop.pacFallback joins the zod-only schema and the type. - The old app-server shim copy and the pre-lidge-jun#6365 intercept code from this branch are dropped in favour of dev's and lidge-jun#6365's. - PAC tests move to tests/clients/desktop-unblock-*; the guide and the structure doc describe PAC fallback.

Summary
Second of three PRs split out of #5947 by @lcxhh521. Stacked on #6361 (the app-server shim); review only the commit on top of it. After #6361 lands, this branch is rebased onto
devand retargeted.This carries #5947's local-CA send-unblock intercept, kept experimental, macOS only, and off by default (
chatgptDesktop.unblockSend,chatgptDesktop.port):chatgpt.comtraffic from the ChatGPT desktop app using a locally issued CA, relays HTTP and WebSocket traffic upstream, and clears the plain-quota send gate in usage responses. It reuses the gate helpers fromsrc/chatgpt/app-server-shim/gate-rewrite.tsand does not redefine them.ocx chatgpt launch | restore | status | install-watchergain the intercept mode next to the existing shim mode.src/lib/socks5-handshake.ts(used bysocks5-fetch.tsand the upstream dial), with its own tests.http://proxy without an explicit port now dials 80 instead of an invented 8080, and a proxy that closes mid-handshake fails the upstream dial (502) instead of hanging the upgrade (tests/clients/desktop-unblock-ws-upstream.test.ts).Security cost (please weigh this before anything else): enabling this mode issues a local CA and asks the user to trust it in the login keychain (
security add-trusted-cert). The listener then terminates TLS forchatgpt.comand relays the signed-in account's credentials. That is a machine-wide trust change for a quota UI convenience.Evidence against it: in #6196 (2026-09-27..29) TooSpace ran this intercept on current macOS Desktop builds, and the listener saw zero established connections in about 20 hours. The bundled app-server owns the
chatgpt.comsockets, so the gate reads never pass through it. The app-server shim in #6361 is the mechanism with field evidence.It also conflicts with the 260928 maintainer design, which rejects CA installation. It is offered so the decision can be made on a reviewable diff. Closing this PR is an expected outcome.
Security review requested per MAINTAINERS.md (TLS termination, credential relay, keychain trust, new outbound transport).
