Summary

Adds an opt-in chatgptDesktop.unblockSend integration for the ChatGPT desktop app. When enabled, the service binds a local TLS listener for chatgpt.com (shared intercept CA, port defaults to public port + 200) and rewrites the subscription-quota send locks out of the payloads the desktop app reads:

  • blocked_features[send|tpp_send] and limits_progress[send] entries in conversation payloads
  • rate_limit.allowed / rate_limit.limit_reached gate flags in the /backend-api/wham/usage snapshot and usage stream

Quota display stays honest: percentages, reset timestamps and the upsell banner pass through byte-identical, so the app keeps showing the account's real usage while the composer unlocks for turns whose model calls are routed to third-party providers by opencodex.

Launch watcher

The Chromium resolver rule only applies when the app is launched with it, so a normal Dock/Spotlight launch reaches the real chatgpt.com and the composer locks again. The second commit adds a launchd agent that watches the app's Electron SingletonLock (written on every launch) and, exactly once per launch, restarts the app with the resolver rule if it was started without one. There is no resident polling process: launchd wakes the one-shot script on the lock event and the script exits after one check.

  • New CLI: ocx chatgpt status|install-watcher|uninstall-watcher|launch
  • The watcher only acts when the opencodex intercept listener is actually listening, so with the feature off the app stays native.
  • Install is idempotent (bootout + bootstrap) and survives reboots.

Design notes

  • Launch rule (--host-resolver-rules=MAP chatgpt.com 127.0.0.1:<port>) is printed at startup; only the exact host chatgpt.com is mapped, so auth.openai.com and the codex-cloud WebSocket stay native.
  • Fire-and-forget lifecycle like the Claude intercept: a bind failure degrades to a warning and never blocks startup.
  • SSE is rewritten line-buffered; untouched streams keep their exact chunking and line endings.
  • Config group is opt-in, off by default, malformed reads as off.

Tests

11 cases over JSON/SSE rewrite, gate flipping, unchanged detection, malformed-entry passthrough and display-field preservation (tests/chatgpt-unblock/rewrite.test.ts). bun run typecheck clean.

Summary by CodeRabbit

  • New Features
    • Added an opt-in integration for the ChatGPT desktop app that removes send-related subscription blocks while preserving quota displays.
    • Added ocx chatgpt commands to check integration status, install or uninstall launch monitoring, and launch the app with the required connection settings.
    • Added configuration options for enabling the integration and selecting its local port.

Review readiness checklist

This PR stays in draft until every box below is ticked. Tick all four boxes once the requirements are met:

  • Required local validation passed; commands, results, and any full-suite exception are documented.

  • I pushed my PR to a recent dev commit (at most 10 behind; a maintainer may still ask for the exact tip before merge).

  • I resolved all correct Codex and CodeRabbit findings.

  • My PR is ready for review.

`preview` carries its own release-bump commits (`release: v2.36.0-preview.20260829`), which
are not on `dev`, so the promotion cannot fast-forward: `package.json` is the only conflicting
path. Resolved to the version this train publishes, `2.36.0-preview.20260830`, which moves the
`preview` channel forward from the 20260829 tip.

Every other path takes `dev` (`bb6a6fbdf`) unchanged.

…rkflow call (lidge-jun#3262)

Both v2.40.0 release dispatches (33615174183 preview, 33615177849 main) died
at startup_failure: a workflow_call cannot grant its callee more than the
calling job holds, and dev-version-bump.yml's job declares contents+pull-
requests write. lidge-jun#3129 wired the call but never dispatched a release, so this
is its first live run. The caller job now declares exactly the callee's two
permissions; no other job in release.yml gains anything.

Brings the reviewed dev head (81a1fc1) onto preview. The only conflict is
package.json's version, resolved to the preview channel's next version rather
than to either side: preview carried 2.40.0-preview.20260902 and dev carries
2.41.0, and neither is what this publish is.

[WRONG BRANCH] release: refresh preview onto the audit-clean dev head for v2.41.0-preview.20260903
v2.41.0 published from main while this promotion was in flight, so the preview
line has to move past it: a 2.41.0-preview version is now BEHIND a released
one, which tests/release-version-line.test.ts refuses and npm would refuse
after it.

dev moved to 2.42.0 in lidge-jun#3354, the automatic post-release bump. Preview follows
the same line at 2.42.0-preview.20260903, which is the conflict resolution
here: neither side's value, because neither is what this publish is.

Also brings the three CI timing-flake fixes from lidge-jun#3351, which is what preview
CI failed on twice at 491ffcf.

Preflight: 2.42.0-preview.20260903 unpublished on npm, no v2.42.0* tag, no
GitHub release, and it moves preview forward from 2.40.0-preview.20260902.

…view

preview had diverged from main: it carried 28 merge commits main did not have,
while main carried 23 preview did not, so preview could not fast-forward.
The divergence was history only - the sole CONTENT difference between the two
branches was the package.json version line.

This merge takes main (48f8186, the v2.42.0 release commit) into preview and
resolves the tree to main's content, so preview now matches the released tree
exactly apart from its own prerelease version line.

The version could not stay at 2.42.0-preview.20260903: v2.42.0 has published,
and compareReleaseTags ranks that prerelease BEHIND its own stable release
(-1), which is what tests/release-version-line.test.ts fails on. preview opens
the next prerelease line at 2.43.0-preview.20260904, matching dev's 2.43.0.

…ts attach (lidge-jun#5555) (lidge-jun#5558)

GitHub freezes a release when it is published, so the attach step's upload
came back HTTP 422 "Cannot upload assets to an immutable release". Every
release from v2.55.0 to v2.60.0 therefore shipped with zero assets and the
desktop updater had nothing to download.

Create the release as a draft and flip it to published in attach-release,
after the verified bundle is uploaded. Release notes still come from the
validated notes file written at creation.

📝 Walkthrough

Walkthrough

The change adds an opt-in ChatGPT desktop integration. It rewrites send-related JSON and SSE data through a local TLS listener, starts that listener with the server, and adds CLI commands and a launchd watcher to apply the resolver rule when ChatGPT starts.

Changes

ChatGPT desktop send-unblock

Layer / File(s) Summary
Rewrite send-lock payloads
src/chatgpt/desktop-unblock/rewrite.ts:1-146, tests/chatgpt-unblock/rewrite.test.ts:1-151
The rewrite helpers remove matching send and tpp_send blocks, remove exhausted send limits, and update closed rate-limit gates recursively. Tests cover nested payloads, preserved display data, malformed input, and unchanged results.
Relay and rewrite upstream responses
src/chatgpt/desktop-unblock/listener.ts:1-140
The listener relays requests to the configured upstream over TLS. It rewrites JSON and event-stream responses, filters selected response headers, and passes other response bodies through.
Configure and start the listener
src/types/config.ts:958-972, src/config/schema/config-schema.ts:233-238, src/chatgpt/desktop-unblock/runtime.ts:1-75, src/server/index/chatgpt-unblock-lifecycle.ts:1-34, src/server/index.ts:199, 627, 739, 773
Adds chatgptDesktop settings and port selection. When enabled, the server creates a local certificate and starts the listener after the public listener binds. Shutdown stops the listener. Startup failures are warned and resolve as an unavailable optional integration.
Install and manage the launch watcher
src/chatgpt/desktop-unblock/launch-watcher.ts:1-182
Adds a launchd agent that watches ChatGPT’s SingletonLock. If the listener is available and ChatGPT is running without the resolver rule, the script quits and relaunches the app with the rule. Adds installation, removal, status, and direct-launch functions.
Expose ChatGPT integration commands
src/cli/chatgpt-command.ts:1-91, src/cli/dispatch.ts:946-949, src/cli/registry.ts:465-477
Adds status, install-watcher, uninstall-watcher, and launch subcommands. The status command reports listener, watcher, and app state. Watcher installation requires chatgptDesktop.unblockSend to be enabled.

Merge Risk: 🟡 Moderate · up to 57d60

The new ChatGPT desktop send-unblock integration does not currently work as described. The app is launched without the Chromium resolver switch, so traffic never reaches the local listener, and status output agrees with the broken launch. Several additional issues can cause failed requests, false install success, or a relaunch toward the wrong local service. Because the feature is off by default, existing users are unaffected, but these issues should be fixed before merge.

Use one switch-bearing resolver argument for launch and detection. Both launch paths pass a bare MAP ... rule rather than --host-resolver-rules=MAP .... Both command-line checks then expect the bare form. The app therefore remains on its normal route, while a corrected launch would still be reported as unflagged. Chromium documents MAP as the value of the switch. (chromium.googlesource.com)

Add regression tests for sseRewriteStream and relayWithSendUnblock.

This file adds a new request and response relay. The file already has a test seam: both functions are exported, and the relay accepts fetchImpl. No test in this cohort exercises either function. The tests should cover these risk areas:

  • A data: line split across two chunks. It must be rewritten once, and every byte must still arrive.
  • CRLF line endings. See the comment on src/chatgpt/desktop-unblock/rewrite.ts Lines 140-146.
  • An upstream 204 or 304 response with content-type: application/json. See the comment on Lines 112-121.
  • A fetchImpl rejection. The relay must return a 502 with the error envelope.
  • The response headers after the relay. content-encoding and content-length must be removed, and set-cookie must be kept.

When you write the tests, collect all chunks into one buffer and split on \n\n. Do not assume one event per chunk.

Put the tests in tests/chatgpt-unblock/listener.test.ts, then run bun test tests/chatgpt-unblock/listener.test.ts and bun run typecheck.

The path instructions say: "A behavior change in src/ should come with a focused regression test near the existing tests for that subsystem." The chunking advice comes from a learning: "Tests should accumulate/decode all chunks into a single buffer and split on the frame delimiter."

Handle null-body statuses before response rewriting.

If the upstream returns application/json with status 204, 205, or 304, upstream.text() produces an empty string. new Response("", { status: upstream.status }) then throws because these statuses cannot have a non-null body. The rejection escapes relayWithSendUnblock and can fail the desktop request. Handle HEAD responses before content-type processing as well.

🐛 Proposed fix
   const headers = responseHeaders(upstream);
+  const nullBodyStatus = [204, 205, 304].includes(upstream.status);
+  if (nullBodyStatus || req.method === "HEAD") {

CRLF-framed SSE data: lines are never rewritten.

The SSE specification allows \r\n line endings. sseRewriteStream in src/chatgpt/desktop-unblock/listener.ts (Lines 59-61) splits only on \n. Each line then keeps its trailing \r. The regex on Line 141, /^(data: ?)(.*)$/, has no s flag, so . cannot consume \r. Also, $ without the m flag matches only at the end of the input. As a result, exec returns null for every CRLF line. The send lock and the rate_limit gate then pass through unchanged, and nothing reports the failure.

The same regex also rejects valid JSON that contains a raw U+2028 or U+2029 inside a string, because . does not match those characters either.

Fix: remove the trailing \r before matching, add the s flag, and add the \r back to the output. Add a test such as stripSendBlocksFromSseLine('data: {"blocked_features":[{"name":"send"}]}\r') in tests/chatgpt-unblock/rewrite.test.ts.

The OpenGrep exec-js hint on Line 141 is a false positive. RegExp.prototype.exec is not child_process.exec.

🐛 Proposed fix
 export function stripSendBlocksFromSseLine(line: string): string | null {
-  const match = /^(data: ?)(.*)$/.exec(line);
+  const cr = line.endsWith("\r") ? "\r" : "";

Reject or replace an out-of-range derived port.

If the public port is 65400 and chatgptDesktop.port is unset, this calculation returns 65600. The listener cannot bind that port, although the public proxy can start. Validate the derived port before listener startup. Tell the operator to set an explicit intercept port when the default cannot fit.

챗지피티 데스크톱은 사용량을 다 쓰면 입력을 잠급니다. 이 풀리퀘스트는 그 잠금만 이 컴퓨터에서 푸는 기능을 더합니다. 기본값은 꺼짐입니다. 켜면 앱이 chatgpt.com으로 보내는 통신을 로컬 TLS 서버가 받아, 진짜 chatgpt.com으로 다시 보냅니다. 답장에서 send 잠금과 rate_limit의 막힘 표시만 바꿉니다. 사용한 비율, 다시 풀리는 시각, 업셀 배너의 값은 그대로 둡니다. 맥에서는 앱이 켜질 때 그 길이 빠졌으면 앱을 끄고 다시 켜는 launchd 감시자도 있습니다. 명령은 ocx chatgpt status, install-watcher, uninstall-watcher, launch입니다.

받는 브랜치는 main입니다. 기여는 dev로 갑니다. dev에는 이 폴더가 아직 없습니다. 같은 기능으로 열려 있는 다른 풀리퀘스트도 없습니다. 설정은 src/types/config.ts와 src/config/schema/config-schema.ts에 들어가 있습니다. 예전에 닫힌 #4974가 비슷한 시도였습니다.

src/chatgpt/desktop-unblock/runtime.ts chatgptUnblockResolverRule - 돌려주는 문자열은 MAP chatgpt.com 127.0.0.1:포트입니다. 크로미움이 길을 바꾸는 인자는 --host-resolver-rules=MAP ... 한 개입니다. 시작 로그는 그 인자를 안내합니다. ocx chatgpt launch와 감시자 스크립트는 MAP만 --args로 넘깁니다. 앱은 원래 chatgpt.com으로 가고, 잠금은 안 풀립니다.

src/chatgpt/desktop-unblock/launch-watcher.ts buildChatgptUnblockWatcherScript - 이미 규칙이 있는지도 MAP만 찾습니다. 로그대로 스위치를 붙여 켠 앱은 규칙이 없다고 봅니다. 감시자는 그 앱을 종료한 뒤, 스위치 없이 다시 엽니다.

src/chatgpt/desktop-unblock/launch-watcher.ts의 lsof - 그 포트에서 듣기만 하면 우리 서버로 칩니다. 다른 프로세스가 포트를 차지해도 챗지피티를 재시작합니다. src/cli/chatgpt-command.ts의 status도 같은 방식으로 듣는 중이라고 적습니다.

src/chatgpt/desktop-unblock/launch-watcher.ts installChatgptUnblockWatcher - launchctl bootstrap의 성공 여부를 버립니다. 실패해도 설치됐다고 출력합니다. 제거할 때는 bootout이 실패해도 plist와 스크립트를 지웁니다.

src/chatgpt/desktop-unblock/rewrite.ts stripSendBlocksFromSseLine - 줄 끝이 \r\n이면 data: 줄을 고치지 못합니다. 정규식의 .가 \r을 먹지 않습니다. 사용량 스트림이 CRLF면 잠금이 그대로 통과합니다.

src/chatgpt/desktop-unblock/listener.ts relayWithSendUnblock - JSON이라고 온 204, 205, 304에 빈 본문을 붙여 새 응답을 만듭니다. 그 상태 코드는 본문이 있으면 예외가 납니다. 앱 요청이 실패할 수 있습니다.

src/chatgpt/desktop-unblock/runtime.ts chatgptUnblockPort - 포트를 안 적으면 공개 포트에 200을 더합니다. 공개 포트가 65336 이상이면 결과가 65535를 넘습니다. 서버는 경고만 하고 계속 뜨고, 이 기능만 빠집니다.

tests/chatgpt-unblock/rewrite.test.ts - JSON을 고치는 테스트만 있습니다. 실행 인자, 감시자, 본문 없는 상태 코드는 테스트가 없습니다.

메인테이너의 판단이 필요한 지점

이 드래프트를 dev로 옮길지, 닫고 dev에서 다시 열지를 정해야 합니다. 브랜치는 main에서 나갔습니다. main과 dev는 서로 다른 커밋이 있습니다.

감시자가 사용자의 챗지피티를 자동으로 끄는 동작을 둘지도 정해야 합니다. 감시 경로는 Library/Application Support/Codex/SingletonLock이고, 실행 앱은 /Applications/ChatGPT.app입니다. 실제 앱이 그 파일에 락을 쓰는지 확인이 필요합니다. 경로가 다르면 감시자는 깨어나지 않습니다.

unlockRateLimitGate는 어느 깊이의 rate_limit이든 allowed를 켭니다. 사용량 화면만 열지, 다른 한도도 같이 열지를 정해야 합니다.

너의 추천

대상을 dev로 바꾸세요. 충돌이 크면 닫고 dev 최신에서 다시 여세요.

머지 전에 실행 인자를 시작 로그와 같은 --host-resolver-rules=MAP chatgpt.com 127.0.0.1:포트로 맞추세요. 검사도 그 전체 인자를 보게 하세요. 포트를 연 프로세스가 우리 리스너인지 확인하고, launchctl이 실패하면 실패로 끝내세요. \r이 붙은 data: 줄과 본문이 없는 상태 코드도 고치고, 그 경우를 테스트에 넣으세요. 기능이 기본으로 꺼져 있어도, 켜면 앱을 끄고 길을 잘못 바꿉니다.

Comparative design review: native queue fallback vs desktop interception

Reviewed 57d604d, compared with the on-demand native-queue approach in luvs01#619 at b8cfba1. This is a technical COMMENT, not an approval or a request to discard this author's work.

These approaches are not equivalent replacements

Concern This PR Native queue fallback (#619)
User experience Aims to restore the existing desktop composer, with packaged ocx chatgpt operations Deliberately sends one message through another input surface; does not repair the composer/model picker
Normal operation Once enabled and correctly launched, the whole exact chatgpt.com hostname goes through the TLS relay, including ordinary requests No helper activity until invoked; an invocation sends a normal message even when quota is available
Routing/authorization Changes client-visible account/feature gates, but currently has no conversation/provider eligibility check Leaves account state and routing untouched; also does not prove provider health or authorization
Lifecycle Listener configuration, a persistent launchd registration, client launch arguments, and certificate trust must agree One-shot process; no persistent enable switch. Already accepted queue items still require native queue cancellation
Platform evidence Launcher/watcher is macOS-specific; the reported 11 tests exercise rewriting, not the actual desktop transport Bash/PowerShell wrappers have three-platform offline CI; real Desktop/provider completion remains unverified

The integrated composer UX is a real advantage of this proposal. Conversely, #619 is not a complete competing implementation of that UX and should not be advertised as one. I would retain a supported, non-intercepting input path as the low-impact fallback, and treat interception as a separate, explicitly consented capability with stronger scope/readiness/reversal requirements.

Additional findings

The four inline comments cover issues not already covered by the eight existing CodeRabbit threads: endpoint/provider eligibility, preserving non-quota send blocks, the on→off transition for an already-mapped app, and the missing desktop-trust readiness/setup contract. The first two were reproduced with the published functions; the latter two are source-level lifecycle/setup findings, not claimed live desktop reproductions.

In particular, off by default is implemented, but it is not the same as either no interception while ordinary usage is available or returning an already-running mapped app to native networking when turned off. Also, preserving used_percent and reset values does not make a changed account-wide allowed flag truthful for every native and third-party conversation sharing that snapshot.

Existing bot findings: verified, not duplicated

I independently reproduced the already-reported launch-switch/detection problem (#discussion_r4090101204), null-body status handling (#discussion_r4090101228), CRLF SSE handling (#discussion_r4090101231), derived-port overflow (#discussion_r4090101239), and unescaped plist paths (#discussion_r4090101207). The listener-identity and launchctl-result concerns are already tracked; those threads should remain with the author/reviewers rather than receiving duplicate new findings here.

Validation and limits

Copied the four reviewed source files into an isolated workspace and verified their Git blob hashes against GitHub before execution: rewrite.ts 91719c13d88f68a54dc7a5e61c9411f1485859ed; listener.ts 9b4bdf4af95a0f9c8442875bd8bc94fd146bd404; runtime.ts 2171ee85f90507eaf4ac77beb17ca39e10ffe818; launch-watcher.ts 0f7fc8bd50a9dfae6f631ea034b5777704f0af21.

Ran 14 targeted checks using Node 22.16.0 type erasure and the generated Bash script with fake process commands: 4 positive controls passed; 10 desired-behavior assertions failed and reproduced the concerns. This is not ten distinct bugs: three assertions are the 204/205/304 variants and two cover the same launch-argument issue. Controls confirm off/client-role startup does not enter CA/listener work, ordinary allowed JSON retains its body bytes, LF SSE rewriting handles split chunks, and an absent listening port causes no watcher restart.

For the isolated relay tests, the header-forwarding import was mocked; body/status/SSE function logic was unchanged. No real authentication, certificate installation, desktop restart, launchd registration, network/model call, or user configuration change was performed. These are not Bun-suite or real macOS/Windows/TLS integration results. Bun and dependencies were unavailable here; actual transport/trust/remote-control verification remains necessary.

Finally, this feature PR still targets main; please retarget/rebase to dev per the existing branch gate. Exact-head Cross-platform CI and React Doctor currently report action_required, not success. Please keep independent security review for the new credential-carrying TLS boundary, and add user-facing setup/disable documentation and focused listener/lifecycle/launcher tests before readiness. I have not opened a duplicate competitor or modified this branch.

[P1] Restrict rewriting to an eligible conversation/provider and known response surfaces.

The URL is used to construct the upstream target, but the decision here checks only content type; the SSE branch is equally broad. chatgptUnblockEnabled only checks the global toggle/runtime role. There is no endpoint allowlist or evidence that this particular conversation routes to an authorized, usable third-party provider. Because the resolver rule maps the whole hostname, unrelated JSON containing a nested rate_limit is rewritten too, and the account-wide usage snapshot is changed even for native-provider conversations.

Offline reproduction with the unchanged relay function and injected fetch: request /review-fixture/not-a-composer-endpoint, return {"result":{"rate_limit":{"allowed":false,"limit_reached":true}}} as JSON. The relay returns allowed:true, limit_reached:false. This is a synthetic fixture demonstrating the missing boundary, not an assertion that a production endpoint uses that exact path/schema.

Please preserve unrelated/unknown/native-route responses and upstream authorization errors unchanged. Use the existing OpenCodex routing authority to establish eligibility and narrowly identify the actual composer readiness surface. If a global account snapshot cannot safely distinguish mixed native/third-party conversations, do not infer that the entire account is allowed from this opt-in flag; retain the explicit native-queue fallback instead. Add negative tests for unrelated paths and absent/unsupported provider eligibility.

[P1] Do not treat every send/tpp_send block as an exhausted-quota block.

This predicate ignores block_reason and available usage. The PR's own fixture includes tpp_send with work_subscription_required; that entry is removed even with rate_limit.allowed:true, limit_reached:false, and a positive send balance. I reproduced a payload with those flags, limits_progress:[{feature_name:"send",remaining:2}], and blocked_features:[{name:"tpp_send",block_reason:"work_subscription_required",resets_after:null}]: the result has an empty blocked_features array.

Thus ordinary usage availability is not a no-op when a non-quota eligibility block is present. Unknown future send-block reasons are also removed by name alone. This does not make the upstream operation authorized; it makes the client offer an operation without preserving the original explanation.

Please distinguish verified composer-only quota conditions from subscription/policy/unknown conditions, preserve non-quota and unrecognized entries, and require the route eligibility described in the listener comment. Add the open-quota/non-quota-block case as a preservation regression rather than broadening the unconditional removal expectation.

[P1] Define a reversible off transition for an already-mapped desktop app.

Stopping this handle closes the listener, but cannot remove the --host-resolver-rules argument from the running desktop process. Consider a user who trusts the CA and launches with the correct full command already printed by chatgpt-unblock-lifecycle.ts, then disables the feature and restarts/stops OpenCodex while leaving the app open: startup now returns null, while that app still maps chatgpt.com to the closed loopback port. This strands ordinary chatgpt.com requests, not just the blocked composer. uninstallChatgptUnblockWatcher only unloads/deletes watcher files and does not restore the current app process either.

This is independent of the already-reported missing-switch bug in the other launcher paths; the printed manual launch command already supports entering the mapped state. The source-level transition has no recovery handling. I did not reproduce it against a live desktop here.

Please provide/document an explicit safe disable/restore sequence: detect and report a mapped app with no usable listener, explain that a full quit and flag-free relaunch is required, and offer any assisted restart only with user consent and work-preservation guidance. Add lifecycle coverage for enabled→disabled and listener failure. A warning-only server startup failure is not a native-network fallback for an already-mapped client.

[P2] Separate 'listener bound' from 'desktop certificate trust ready', and document the missing setup.

The reused CA helper creates/loads PEM files; src/claude/intercept/local-ca.ts explicitly scopes its existing trust integration to Claude's NODE_EXTRA_CA_CERTS and never installs an OS trust root. Creating a leaf for chatgpt.com does not establish trust in the desktop's Chromium network stack. The new launch/watcher/status paths perform no desktop-trust preflight; the startup log only prints a CA path and resolver command. The config comment says the CA must be trusted once, but this PR adds no user-facing instructions or verification for that prerequisite.

On an otherwise fresh installation, following the printed resolver command is therefore not a complete working setup. Sharing the CA files with Claude cannot establish that the desktop client trusts them. Electron's certificate-verification documentation also distinguishes the Chromium verification result from merely having a local certificate: https://www.electronjs.org/docs/latest/api/session#sessetcertificateverifyprocproc.

Please report trust as a separate readiness condition, document a consented platform-specific setup/removal path and how it is verified, and avoid claiming launch success as integration readiness while trust is unknown. Do not disable certificate verification or silently install trust roots as a fix. Keep the independent security review, including the scope of authentication-bearing requests passing through this listener.

Thanks @luvs01 and @lidge-jun for the detailed review — very useful. Responses below.

On the core concern (quota vs eligibility): to clarify intent, this feature does not grant any server-side entitlement — OpenAI's servers keep enforcing every limit, and the actual model calls for unlocked turns are routed by opencodex to third-party providers the user has configured and pays for themselves. That said, you're right that the current implementation is broader than that story justifies: it strips any send/tpp_send block, including eligibility blocks like work_subscription_required. That's a scoping bug, not a design point. I'll narrow the rewrite to pure usage-quota conditions (exhausted send limits, rate_limit-gated flags) and preserve every blocked_features entry with a non-quota or unknown block_reason, with a regression test for exactly the case you reproduced (open quota + subscription-required block must pass through untouched).

Rewriting scope too broad [P1, listener]: agreed, the hostname-wide mapping is too coarse. I'll restrict rewriting to the conversation/composer and usage endpoints the composer actually consumes and pass everything else through byte-identical.

Bare MAP in launch/detection paths (also flagged by CodeRabbit): confirmed — both launch paths pass a bare MAP ... and both detection paths search only MAP. Will pass and detect --host-resolver-rules=MAP ... as one complete argument.

Port ownership (lsof): agreed — will verify the listening process is actually our child listener (pid check) before restarting the app.

launchctl result handling: agreed — will propagate bootstrap/bootout failures instead of discarding them.

CRLF-framed SSE lines, null-body statuses (204/304), derived-port overflow: all three confirmed; will fix with regression tests, including the listener-level tests suggested.

Reversible off transition [P1, runtime]: agreed — I'll add an explicit safe-disable path: ocx chatgpt status detects a mapped app with no usable listener, warns, and prints (or offers) the flag-free relaunch.

Certificate trust [P2]: agreed this is a missing prerequisite — will document it and surface trust as a separate readiness condition in ocx chatgpt status rather than implying "listener bound" means "ready".

Process: retargeting to dev as recommended. Checklist boxes stay unticked until local validation is documented and the branch sits on a recent dev commit. The two direction-level decisions — whether the watcher's quit-and-relaunch behavior is acceptable, and whether this integration fits the project at all given the MITM/ToS considerations — are yours to make; happy to drop the watcher or close this in favor of a discussion issue if you'd prefer that route.

Follow-up review — additional findings (P1/P2/P3)

Continuing from the earlier comparative review. These are intentionally scoped to issues not already covered by the four prior inline comments, the author's acknowledged list, or the eight CodeRabbit threads (bare-MAP launch/detection, null-body statuses, CRLF SSE, derived-port overflow, plist escaping, lsof ownership, launchctl result handling — all confirmed already tracked).

[P1] Transport coverage is unverified for WS/Upgrade and HTTP/3 on the mapped host

The relay is fetch-based and has no upgrade path. Once chatgpt.com is mapped to the listener, any request the desktop app opens on that host — including WebSocket upgrades or HTTP/3 (Alt-Svc → QUIC, which bypasses a TCP listener entirely) — terminates here or fails silently. The PR verifies JSON/SSE rewriting but does not establish which protocols the app actually uses on chatgpt.com. If any WS or QUIC traffic exists on this host, the feature breaks app functionality beyond the composer. Suggest: capture evidence of the app's actual transports on the mapped host (or explicitly reject upgrades with a visible error) before this lands.

[P2] Watcher quits the app mid-use without consent or drain

osascript -e 'quit app "ChatGPT"' + sleep 3 + relaunch fires on every SingletonLock event where the app lacks the flag — including while the user is mid-conversation or has draft text in the composer. In-flight turns survive in the app-server, but unsent drafts and window state do not. This is the "direction-level decision" the author already flagged; concretely, consider deferring the relaunch to the next natural launch (marker file), or gating it behind a first-run consent prompt, rather than auto-quitting a running app.

[P3] ocx chatgpt status misreports on non-macOS platforms

status shells out to lsof and pgrep, which don't exist on Windows — every check silently reports "not listening / not running" instead of "unsupported platform". The feature is macOS-only today, so a platform gate or an explicit unsupported message would keep the CLI honest. Minor adjacent nit: the watcher script logs to $HOME/.opencodex/chatgpt-unblock-watcher.log while errPath uses configDir, which diverges when XDG_CONFIG_HOME or a custom config dir is set.

None of these overlap the existing threads; happy to re-check once the acknowledged fixes land.

Maintainer triage: priority: P3 — experimental local TLS intercept of chatgpt.com (needs security review).

Criteria (P3): Low: new provider/client integration, large or experimental feature (>2000 LOC or >50 files), RFC/roadmap, or long-stale branch.

Rebased onto current dev: branch rebase/pr-5733 @ cc26bf452 (compare). Your fork branch could not be updated directly; you can adopt it with git fetch https://github.com/lidge-jun/opencodex.git rebase/pr-5733 && git reset --hard FETCH_HEAD && git push --force-with-lease. CI was intentionally not run.
