Problem and behavior

Codex Desktop can disable its local composer when the signed-in ChatGPT account is exhausted even when the selected model uses an independent provider. This draft adds explicitly enabled Windows compatibility controls while preserving the existing login. Native submission after actual exhaustion remains unverified; this PR is not ready to merge or release.

The panel manages a 30-day, chatgpt.com-constrained, server-authentication-only CA, CurrentUser DPAPI storage, and fingerprint-bound trust/removal/renewal. The optional loopback relay starts in Observe. After fresh eligible exhaustion is observed, a separately acknowledged account-wide trial can adjust two WHAM usage booleans for at most three minutes. Actual quota amounts, credits, spending restrictions, and upstream enforcement remain unchanged. The response layer cannot identify the selected conversation provider, so this is an account-wide UI trial rather than a provider-scoped admission decision.

Lifecycle checks bind native routing, credential generation, assessed Windows package identity, and runtime ownership. A managed restart accepts only the serving runtime's exact PAC and fresh generation, rechecked before activation. Stop invalidates that attestation. Startup preference saves no consent or Apply state and resumes Observe only. Unknown conversation restrictions, including blocked_features and limits_progress, pass unchanged.

Current upstream integration

Head f8c611abbbfec915504e98f35be914f7584585d2 incorporates dev 37ad7e771b38ef0371b8b9837ed36587ad179e08. The six overlapping config, management dependency, and structure-document conflicts are resolved. Both desktop startup validation and upstream blocked-model redirects/Anthropic route validation remain present; low-quota management dependencies are retained.

A plain rebase tried to replay historical upstream integration commits as new changes, including an old root snapshot. That attempt was aborted back to the verified head; a merge preserves the reviewed commits and current upstream changes. No previous commit was force-pushed away.

UI evidence

These screenshots render the current source tree 220018569d125457fe47badf1dae0e78f891da9e with synthetic API fixtures. They demonstrate consent and observation wording, not a live certificate registration, account exhaustion, or recovered composer. The headless capture made zero mutation requests and had no browser console errors or page errors; the unacknowledged confirmation remained disabled.

Validation at the integrated source

  • Runtime, certificate lifecycle, routing, management API, startup, and blocked-model config regressions: 116 passed, 0 failed, 698 assertions, across 15 files.
  • GUI API and mounted panel: 21 passed, 0 failed, 452 assertions.
  • TypeScript, GUI TypeScript/build, structure, privacy, file-size ratchet, and PR delta whitespace checks passed.
  • The local Bun package-bin launcher could not remap the installed shim. The equivalent compiler/check scripts were invoked directly from the checked dependency and source paths; no dependency manifests were changed to work around it.
  • Current-head Cross-platform CI 36503547814 passed, including four test shards, gates, docs and Linux packaged-shell E2E. Windows/macOS full test matrices were skipped and are not counted as platform validation. The prior broad local import-graph run exceeded its 900-second budget; the focused local set above covers the integration boundaries.
  • Rebuilt standalone CLI 2.71.0: seven isolated compiled smoke checks passed, including packaged GUI, DPAPI authority preparation without OS enrollment, stale-write refusal, and test-guarded runtime admission. Its child terminated and listener was released.
  • Built local unsigned MSI 2.71.0-compat.6079 from this source; administrative extraction verified all 93 payload files, package identity/version, CLI hash and the documented three-byte Tauri bundle marker. MSI SHA256: 76903987B60371A37F63E779EBCD0850F2420BC0BDD4C366EB44F5FF1AC7BF3D. This is a locally validated experimental package, not a release or installed-client result.

No installed app, proxy, user configuration, or trust-store entry was changed by this integration. The installed runtime still belongs to 5e2370d132; the new package has not been installed.

Transport scope and remaining gates

The examined Windows build 26.924.2738.0 has a usage-stream path through the renderer HTTP service and Electron net.fetch. Source tracing does not prove authoritative cache consumption or exhausted-account recovery. Diagnostic JSON/SSE counters include test clients; sourceProcessVerified and composerRecoveryVerified remain false.

Issue #6196 reports a macOS app-server transport that bypasses Chromium PAC. This Windows feature does not resolve that design blocker. Prior installed-client evidence covers ordinary local sending, checked login/Chat/mobile/remote preservation, and a managed restart on older source. An ordinary launch after reboot lacked the PAC, so managed routing is not automatically preserved by every launch/update.

  • Current-head hosted checks and required platform validation.
  • Explicit security review of CurrentUser trust, same-user DPAPI reachability, loopback CONNECT, and fallback behavior.
  • Latest-source installed lifecycle and original-composer attachment/IME checks.
  • Natural exhaustion, original-composer submission, and completed response from the intended independent provider.

Keep draft. No merge, release, or automatic production activation is requested.

📝 Walkthrough

Walkthrough

Adds an experimental Windows Codex Desktop compatibility runtime with certificate management, usage observation and correction controls, proxy-aware relaying, management API routes, and a dashboard tab. It also adds PAC-preserving Windows app relaunch behavior, an opt-in proxy-start preference, tests, and documentation.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~60 minutes

Change: Feature

Merge Risk: 🟡 Moderate · up to 6103a

A configuration that passes routing verification may send Codex traffic to a different local listener. Bind verification to the actual listener address before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 6103a

The feature is opt-in and has several explicit safeguards, but its short-lived account-wide correction can be restarted without the newly required observation. A separate routing check does not fully establish that the configured address reaches the intended listener. The resulting exposure is bounded but merits design review.

Retained concerns

  • Medium · security · observed: Expiration, cancellation, and refresh failure leave the prior exhausted observation eligible for another trial within five minutes. This defeats the stated requirement for a new observation after a trial ends, although each attempt still requires identity verification and renewed consent.
  • Medium · security · inferred: The new routing preflight treats a matching port on any allowed loopback hostname as proof of routing to the native owner. In an IPv4-bound configuration, an accepted IPv6 loopback URL need not reach that owner. Whether this mismatch enables correction in a real launch remains unresolved.
Security review details

Security Blast Radius

  • inferred — The trust change is scoped to the Windows current user, but it grants authority over an intercepted chatgpt.com connection for desktop traffic. The correction scope is account-wide rather than conversation-provider-specific; no cross-device or server-enforcement change was established.

Security Findings and Attack Paths

  • observed — No verified security finding is supplied. The fresh-observation replay is established in the new state machine; the routing mismatch is established at preflight, but its complete correction path and effective exposure remain unproven.

Trust Boundaries and Controls

  • observed — Management POST handlers reject non-GUI principals and untrusted ingress. Certificate mutations additionally check the expected fingerprint and exclude a running compatibility runtime; removal and renewal fail closed when desktop-app state is unknown.

Resilience and Maintainability Implications

  • observed — Identity or binding changes clear the observation and advance a generation, preventing an in-flight activation or old output from crossing that boundary. Termination and refresh-failure paths do not provide the same observation invalidation.

Hardening Proposals

  • proposed — Consume or clear the exhausted observation whenever a trial starts or ends unsuccessfully, so a later trial requires a newly observed eligible response as well as new consent.
  • proposed — Compare the configured routing address as well as its port with the actual owner binding, while retaining support for an explicitly IPv6-bound listener.

이 PR은 Windows용 Codex 데스크톱에 실험 화면을 하나 더한다. 위치는 Codex Set의 Desktop compatibility다. 사용자가 직접 켜야 하고, 지금은 초안이다. 하는 일은 이렇다. 30일짜리 인증서를 만들어 이 Windows 사용자의 루트 저장소에 넣는다. 비밀키는 그 사용자만 풀 수 있게 DPAPI로 감싼다. 패널에서 Codex를 다시 열면 chatgpt.com 접속만 이 컴퓨터의 중계를 지난다. 계정이 방금 바닥난 것이 확인되면, 최대 3분 동안 사용량 응답의 두 표시만 바꾼다. 화면은 아직 쓸 수 있는 것처럼 보이고, 실제 잔량과 크레딧과 서버의 거절은 그대로다. 바닥난 계정에서 입력이 다시 되는지는 이 PR도 아직 확인하지 못했다고 적혀 있다. 베이스는 dev다. 같은 화면을 올리는 열린 중복 PR은 없다.

src/codex/desktop-compatibility/windows-certificate-trust.ts:19 - 인증서가 Codex 프로그램 안에만 있지 않다. CurrentUser의 Root 저장소에 들어간다. 이 Windows 계정이 믿는 다른 프로그램도, 이 인증서로 서명된 chatgpt.com을 진짜로 받아들인다.
src/codex/desktop-compatibility/windows-key-protection.ts:14 - 키를 푸는 범위가 CurrentUser다. 51행 주석대로, 같은 사용자로 켜진 다른 프로그램도 이 키를 풀 수 있다. 그 프로그램은 인증서가 살아있는 동안 chatgpt.com으로 위장할 수 있다.
src/codex/desktop-compatibility/runtime.ts:109 - chatgpt.com용 CONNECT 프록시에 비밀번호가 없다. 같은 파일의 기존 프록시는, 손님이 비밀번호를 못 보내는 경우가 아니면 비밀번호를 달라고 적혀 있다. 이 포트는 127.0.0.1이라 이 컴퓨터의 다른 로컬 프로그램도 chatgpt.com 접속을 여기로 넣을 수 있고, 그 내용은 이 중계 안에서 평문으로 풀린다.
src/server/index/desktop-compatibility-startup.ts:26 - startOnProxyStart가 켜져 있으면 프록시가 켜질 때 이 중계가 다시 start() 된다. 사용량을 고치는 Apply는 여기서 호출되지 않는다. 비밀번호 없는 중계는 그때 사용자 확인 없이 다시 열린다.
src/codex/desktop-compatibility/runtime.ts:115 - PAC 결과가 PROXY 127.0.0.1:포트; DIRECT다. 로컬 프록시가 죽으면 앱은 조용히 진짜 chatgpt.com으로 간다. 관찰이 끊겨도 이 한 줄은 앱을 멈추지 않는다.
src/codex/desktop-compatibility/usage-policy.ts:46 - 고치는 값은 rate_limit.allowed와 limit_reached뿐이다. 39행의 rate_limit_reached_type은 그대로다. 한 응답이 "쓸 수 있다"와 "한도에 걸렸다"를 같이 말한다. 입력창이 열리는지, 열린 뒤 전송이 서버에서 막히는지는 아직 확인되지 않았다.
tests/ci-workflows/file-size-ratchet.test.ts:212 - CI의 test 2/4가 여기서 실패했다. scripts/test-layout/layout.json이 2000줄이라 NEW_OVERSIZED다. test 1/4, 3/4, 4/4와 desktop shell은 취소됐고, ci 잡도 실패다.

메인테이너의 판단이 필요한 지점

사용자 루트에 인증서를 넣는 것이 이 실험의 대가다. 인증서 안의 이름 제한은 chatgpt.com이다. 그 인증서를 믿는 저장소는 Codex가 아니라 이 Windows 사용자다. 같은 사용자 프로그램이 키를 풀 수 있다는 점도 코드가 적고 있다. 이 조합을 실험으로 남길지, Codex 프로세스만 믿게 바꿀지 정해야 한다.

사용량 두 칸을 바꾸는 일은 서버 한도를 풀지 않는다. 화면만 달라질 수 있다. 그 화면이 요청을 보내면 그 요청은 사용자의 ChatGPT 세션으로 나간다. 보안 리뷰 체크가 비어 있는 상태에서 합칠 일은 아니다.

너의 추천

초안인 채로 둬라. 합치지 마라. layout.json을 1999줄 아래로 줄여 test 2/4를 다시 통과시켜라. 인증서를 사용자 Root에 넣기 전에는, 같은 사용자 프로그램이 키를 못 쓰게 막거나 Codex만 그 인증서를 믿게 하라. CONNECT 프록시에는 비밀번호를 달아라. 앱이 비밀번호를 못 보내면, 그 프록시를 사용자 루트 인증서와 같이 켜지 마라. PAC는 프록시가 죽으면 DIRECT로 빠지지 않게 하라. 사용량 응답을 고칠 때는 한도에 걸렸다는 표시를 응답 안에 남기지 마라. 바닥난 계정으로 실제 앱에서 전송이 막히는지 보기 전에는 Apply를 끄고 관찰만 남겨라.

Inline comments:
In @docs-site/src/content/docs/guides/codex-integration.md:
- Around line 960-965: Move the Windows full-app restart paragraph from the
reserve-mode section to the end of the Experimental Windows desktop
compatibility section, before the Routed models during Codex reserve mode
heading. Leave the paragraph’s wording unchanged.

In @gui/src/pages/codex-desktop-compatibility.tsx:
- Around line 63-66: In the certificate action builder, gate remove-trust on a
state where trust is registered, rather than adding it for every certificate
with a fingerprint; do not show it for prepared certificates. Gate renew on the
certificate states the server accepts, so unknown or otherwise unusable states
do not receive invalid mutation actions.

In @gui/tests/codex-set-shell.test.tsx:
- Line 152: Update the deep-link test assertion around `calls` to verify that
the recorded requests include the machine settings, certificate, and runtime
endpoints, so an empty request list cannot pass. Keep the existing GET-method
assertion to detect unintended writes.

In @src/codex/desktop-app/windows.ts:
- Around line 223-224: Update restartCodexDesktopApp to catch errors from
adapter.captureRelaunchContext and return a refusal using a dedicated
relaunch-context failure reason. Keep captureWindowsCompatibilityContext’s
handling of non-managed PAC values unchanged.

In @src/codex/desktop-compatibility/connection-store.ts:
- Around line 80-82: The `unlinkSync` cleanup in the `finally` block can replace
the original publication error and triggers unsafe-finally lint. Refactor the
cleanup around `created` and `temporary` so cleanup failures are recorded
without throwing from `finally`, preserving any in-flight error and surfacing
the cleanup failure only when no earlier error exists.

In @src/codex/desktop-compatibility/runtime.ts:
- Around line 46-50: Update UsageRelayController.rewriteJson’s contextValid flow
to use a cached buildSupported verdict instead of triggering desktop discovery
for each usage record. Initialize the verdict at startup and refresh it from the
lifecycle timer regardless of activation mode, keeping refreshes out of
contextValid so requests never perform the synchronous probe.

In @src/codex/desktop-compatibility/windows-package-command.ts:
- Around line 57-63: Update activateWindowsCodexCompatibility to parse the last
non-empty trimmed line of PowerShell output, and convert JSON parsing failures
to desktop_compatibility_activation_unverified so relaunch does not propagate a
raw SyntaxError.

In @src/lib/desktop-proxy-route.ts:
- Around line 13-16: Update desktopProxyFor to accept a valid HTTP
ALL_PROXY/all_proxy value as the explicit proxy for HTTPS destinations when no
protocol-specific proxy is set, instead of rejecting it as invalid. Preserve
fail-closed behavior for unsupported or malformed proxy values, and add coverage
for this case in the existing desktop-upstream test.

The restart can then stop the root and relaunch through shell:AppsFolder without the PAC. The Windows integration guide promises to preserve an active PAC during an explicit full-app restart. Preserve an explicit empty field as unknown and refuse before signaling.

   for (const entry of processes.filter(value => !members.has(value.parentPid))) {

Hostless file: module URLs are decoded once, so a compiled Windows binary that reports an encoded ~BUN root is recognized as standalone. Network-host, non-file, double-encoded and nested source paths stay on the source path. Narrow reimplementation of the standalone URL fix from #6079.

Author follow-up check used the concurrently updated head 6103a93. Its integration and Draft status were preserved; an independently prepared older-head merge candidate was not pushed over it. The Windows restart/PAC paragraph is already in the compatibility section, immediately before the reserve-mode heading, so that stale documentation thread was answered and resolved without a redundant edit.

React Doctor 36363939577 passed; Cross-platform CI 36363939576 is still in progress. The explicit security review and native exhausted-account end-to-end validation remain required as stated in the current PR body. No trust installation, live-account trial, or deployment approval was performed in this follow-up.

Draft blocker at exact head 89f261b8a97c4781e80f9f79fed0fe3ff631ef0c: captureWindowsCompatibilityContext() accepts any loopback URL matching the PAC shape, and the ordinary Windows full-app restart preserves it without proving equality to the currently running OpenCodex compatibility runtime’s authoritative getPacUrl(). After that runtime stops, a normal restart can reapply a dead PAC; a foreign launcher can also supply a same-shaped local PAC that OpenCodex then preserves. Capture only an exact, currently running runtime-owned PAC (otherwise fall back/refuse), and add stale/foreign PAC regressions. The hosted aggregate is green, but Windows shards and current-head installed-app lifecycle evidence are still missing.

Rechecked new head 5e2370d132: the readiness-gate wait is a useful startup ordering improvement, but it does not address the existing blocker. PAC preservation still accepts the expected URL shape without proving that the currently observed runtime owns/serves it, so a stale or foreign PAC at that location can be preserved as trusted. The exact-head CHANGES_REQUESTED hold remains; bind preservation to an attested current runtime/ownership generation and cover stale/foreign same-shape PAC state.

Addressed the PAC ownership finding in 31084d5dc8cdf7645897847b3b952156f4763a07.

The restart adapter now accepts a managed PAC only when the exact URL is registered by the currently serving, process-local compatibility runtime. Registration happens after the runtime binds/publishes its listeners and receives a fresh generation; cleanup revokes it before closing listeners. Neither connection.json nor the app's URL shape establishes ownership. After the stop ladder, package activation rechecks that same generation, rejecting a stopped or replaced owner even when the replacement serves the identical URL. Ordinary launches without a managed PAC keep their existing path. This is lifecycle attestation, not protection against arbitrary code already running inside the same process/user.

Validation: launch/adapter tests passed (13 tests, 54 assertions). The combined launch/runtime/restart run had 63 passing tests and one cleanup-hook timeout; the affected runtime file then passed in isolation (18 tests, 134 assertions, with a 20-second test timeout). TypeScript passed using the installed package entrypoint because the local Bun binary wrapper failed to remap. Structure, privacy and diff checks passed. Documentation built 537 pages and checked 73,629 links. The actual runtime integration test verifies a served PAC, revocation at stop, and rejection of a prior generation after same-endpoint restart.

This source change is pushed but not installed on the user's PC. The earlier installed managed-restart test applies to the previous build and is not claimed as evidence for this new generation check. Current-head CI, independent security review, original-composer attachment submission and natural-exhaustion recovery remain open. Draft/CHANGES_REQUESTED status is preserved; this does not claim the overall feature is ready.

Compiled follow-up: the Windows standalone CLI at this exact source passed seven isolated packaged-runtime checks (health/ownership, authenticated local dashboard, packaged GUI, TLS-server-only certificate generation, DPAPI persistence without trust enrollment, revision-guarded settings, and guarded runtime loading). The test child exited and its listener was independently confirmed absent. The production CLI hash is unchanged; no live installation or native app restart was performed.

Re-review of exact head 904cb8e: the prior stale/foreign same-shaped PAC ownership blocker is fixed. Runtime registration now binds exact PAC URL plus generation, teardown unregisters it, and Windows capture/restart revalidates URL+generation after the stop ladder; stale, foreign and replaced-runtime cases fail closed.

I am keeping the existing hold because this draft is still conflicting, lacks exact-head functional/Windows installed-package lifecycle proof, and hygiene/enforce-target fail for missing coauthor credit and required UI evidence. The source ownership defect itself is closed; rebase, readiness metadata and real installed-client validation remain before approval.

Exact-head delta review for 4c6f745eb6dbc1dc9df95b2a5c34e75099655797: no new P0-P2 was found in 904cb8ed..4c6f745e, and the prior PAC-owner source defect remains cleared. The package identity and Windows host-casing additions are scoped correctly.

Merge remains HOLD: GitHub reports DIRTY/conflicting, this head is 29 commits behind current dev with 28 overlapping paths, and there is no functional exact-head CI. Hygiene/target metadata also still fail for missing UI screenshot evidence and missing coauthor credit. Please rebase, resolve readiness metadata, run current-head CI, and provide real installed latest-source Windows lifecycle evidence—including natural exhaustion followed by an independent-provider completion from the original composer—before requesting final approval.

Preserve desktop startup validation alongside blocked-model redirects and Anthropic route validation; retain low-quota management hooks and both subsystem contracts. Focused runtime/config/API tests: 116 passed. GUI tests: 21 passed. Typecheck, GUI build, structure, privacy and file-size checks passed. Full suite is deferred to hosted CI; the prior broad import-graph run exceeded 900 seconds. Native exhausted-account recovery remains unverified.

Clear observations on cancellation, expiry and refresh failure, including observations received during a trial. Preserve generation fencing for superseded refreshes and clear failed-trial output counters. Add eight deterministic regressions and retain the secure-cookie preservation assertion.

Validation: the complete activation class and the added tests were transpiled and executed with Node 22.16.0; original 1 pass/7 fail, patched 8 pass/0 fail. Full modified Bun test file syntax transpilation passed. The full Bun/native suites were not run locally; exact-head CI and independent security/native validation remain required. Keep PR in draft.

Pushed 124c741acb5287bfc9971a8f7c52d131bd451e08 to the existing author branch without force after checking the current head and exact two-file diff.

The remaining observation-reuse concern is reproducible: cancellation, timeout, or a failed refresh left the prior exhausted observation eligible for another trial within its five-minute TTL. The activation now consumes that observation when a trial starts and clears observations again on cancellation, expiry, and refresh failure, including a newer observation received during the previous trial. Failed refreshes also clear output counters. The existing generation fence still prevents an old asynchronous refresh failure from erasing a newer trial.

Eight deterministic regressions cover cancel/timeout with and without mid-trial observations, thrown/partial/invalid-count refresh failures, and a superseded refresh failure. They were added to the existing runtime test file, with no layout bypass or skipped test. The existing response-preservation check also explicitly checks the Secure cookie attribute.

Validation performed locally: the complete original and patched activation class plus the exact new regression block were TypeScript-transpiled and executed with Node 22.16.0 using a small assertion adapter. Original: 1 pass, 7 fail. Patched: 8 pass, 0 fail. The entire modified Bun test file passes syntax transpilation. Local and published blob hashes match.

Validation NOT performed locally: the complete Bun suite, full repository typecheck, native Windows lifecycle, certificate enrollment, or exhausted-account composer recovery. Bun is unavailable and repository cloning is blocked by this environment's DNS.

Exact-head hosted CI update: run 36524464211 passed gates (including typecheck, GUI tests and privacy scan), test shards 1/4, 3/4 and 4/4, and the Linux packaged-shell checks, but the run FAILED because test 2/4, job 109264377409, timed out in batch 10. The diagnostic one-file-per-process sweep passed every file in that batch; the runner reported a multi-file-process timeout and exited 124. This is not a passing CI result and the underlying shared-state cause has not been fixed here. One retry of that failed job was accepted by GitHub; no test was skipped or timeout increased, and a retry is not evidence of a root-cause fix. React Doctor passed. Skipped full native platform matrices are not counted as passed.

This only tightens the trial lifecycle. It does not change upstream quotas, credit/spending enforcement, trust stores, installed software, or production configuration. Please keep the PR in Draft; the independent security review, native recovery and full exact-head CI gates remain open.
