Summary

  • Current dev integration (2026-10-02): bfd76c9a50bb856c2699689cbe770718b8baabe4, exact tested tree 850f9f35ef873859b80af6e9802ca2f6bb9543fa. First parent is the previous PR head 822a4a98e420a9e98394e3c2b2792bb3652c1b88; second parent is dev 10428d0120cbceeff997508a28a7a50c4007f7dc. Published and verified by a non-force fast-forward update.
  • Resolved 13 conflicts while retaining both changes: Codex compatibility machine routing props and the upstream Claude page, compatibility copy and upstream strings in all ten locales, and both config/BOM and native-egress documentation. The subsequent upstream credit-opt-in change merged cleanly and was revalidated. PR delta: 102 files, 5,111 additions and 122 deletions.
  • Independent security review and current installed-Windows lifecycle/exhaustion/composer evidence remain explicit final-approval and merge/release holds. No installed app, trust store, credential, service registration or production activation was changed.

Verification

Fresh Linux / Bun 1.4.0 checks on the exact tree above, using the existing dependencies:

  • bun node_modules/typescript/bin/tsc --noEmit: pass.
  • bun test --isolate tests/clients/desktop-compatibility-{authority,build-probe,certificate-service,connection-store,launch,native-identity,relay,routing,runtime,trust}.test.ts tests/clients/desktop-app-restart.test.ts tests/server/management-desktop-compatibility-{routes,runtime-routes,settings}.test.ts tests/server/server-desktop-compatibility-startup.test.ts tests/lib/optional-desktop-upstream.test.ts tests/cli/cli-headless-parity.test.ts tests/ci-workflows/structure-ssot.test.ts tests/test-layout.test.ts tests/test-layout-tooling.test.ts tests/codex-integration/codex-credits-after-limit-main.test.ts tests/codex-integration/codex-credits-after-limit.test.ts tests/config/config-rebase-provenance-writers.test.ts --timeout 30000: 362 pass, 5 Windows-only skips, 0 fail; 2,030 assertions across 23 files.
  • cd gui && bun test --isolate tests: 2,778 pass, 0 fail; 24,109 assertions across 318 files.
  • cd gui && bun run lint && bun run lint:i18n && bun run build: pass. The existing bundle-size warning remains.
  • bun scripts/structure-ssot.ts, bun scripts/privacy-scan.ts, bun scripts/file-size-ratchet.ts, and dev-tree-relative whitespace checks: pass.
  • cd docs-site && ASTRO_TELEMETRY_DISABLED=1 bun run build: pass, 561 pages and 77,830 internal links. An earlier intermediate-tree build was killed during concurrent execution; its serialized retry and the final-tree build both passed.
  • Additional unchanged-path regressions on the preceding integration tree: Claude picker/SOCKS5 tests 52 pass, 0 fail, 182 assertions across 3 files; CLI BOM tests 3 pass, 0 fail, 13 assertions. Their source and test files are unchanged by the final dev integration.
  • The full local backend suite and import-connected suite were not rerun because broad concurrent-worktree execution is disproportionate for this conflict integration. Focused backend regressions and the full GUI suite ran. No assertion or timeout was relaxed. Exact-head Cross-platform CI and React Doctor completed successfully for bfd76c9a. All four Linux shards, aggregate ci, GUI gates, docs, Docker/storage/API checks and Windows keyring/npm-global smoke passed. Full Windows/macOS matrices and the packaged desktop shell were skipped; they do not establish installed-Windows validation. CodeRabbit's current-head review completed successfully for 822a4a98 → bfd76c9a with no new actionable comments; all 10 existing inline threads are resolved.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs and generated structure index remain synchronized.
  • Local validation passed with its scope and remaining gaps documented.
  • Exact-head hosted checks complete successfully.
  • Final approval/merge hold: security-sensitive changes receive independent review.
  • Final approval/merge hold: current installed-Windows lifecycle, original-composer attachments/IME, natural exhaustion and independent-provider completed-response evidence.
  • Current-head CodeRabbit review completed without new actionable comments; local and hosted validation passed. Ready for source/security review. This is not merge approval.

Historical dev-integration checkpoint (2026-10-01, 4c797014)

  • Recorded HEAD: 4c797014aa50ccf35116f851603703a1121169b0; exact tested tree: f0f9828632b36d7be9718a9df9782e45371314cc. Integrates dev 349588e2f1df38bf7e43eac08284c0dd829a78ad with the former PR HEAD as first parent; no force push.
  • Resolved 14 conflicted files by retaining both changes: all ten locales keep compatibility copy and new Anthropic account-threshold guidance; public/internal docs retain both sections; local CA retains the existing server-auth restriction and upstream's test-only extension minting helper. No new certificate enrollment or installed configuration operation was performed.
  • Linux/Bun 1.4.0: compatibility runtime/management suite 119 pass / 3 platform skips / 0 fail (724 assertions, 14 files); certificate/trust/layout focused set 53 pass / 2 Windows-only skips / 0 fail (721 assertions, 6 files). These sets overlap and must not be summed.
  • GUI compatibility/API/credits tests 42 pass / 0 fail, 530 assertions; GUI i18n lint and production build passed. Public docs build passed: 545 pages and 74,737 internal links. Typecheck, structure, privacy, file-size ratchet and dev-relative whitespace checks passed.
  • Full local suite/import-connected suite were not rerun for this conflict-only integration; focused tests cover the conflicted contracts, while exact-head CI provides broader coverage. No assertion or timeout was relaxed. New CI was pending at that checkpoint.
  • Remains Draft: independent security review and exact installed-Windows end-to-end evidence remain outstanding. Linux fixture tests do not prove Windows trust/DPAPI, installed app behavior, natural exhaustion/composer recovery, or release availability. The user's installed compatibility build is unchanged.

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 PR 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.

Historical upstream integration (f8c611ab)

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 recorded 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.
  • Revision-specific 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 aggregate checks passed at bfd76c9a (run 37004328614).
  • Required native Windows validation; skipped platform jobs do not count.
  • 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.

Source/security review is requested. No merge, release, or automatic production activation is requested; the native evidence and independent security-review holds remain.

Summary by CodeRabbit

  • New Features

    • Added an experimental Windows Codex Desktop compatibility option with dashboard controls for certificate setup, runtime status and actions, and an optional setting to resume observation when the proxy starts.
    • Added guarded usage observation and a time-limited, account-wide trial requiring explicit confirmation and an eligible exhaustion snapshot.
    • Added compatibility-aware Codex launch and restart handling, plus support for configured proxy routes.
    • Expanded setup, safety, limitations, and management API documentation, with dashboard text available in eleven languages.
  • Bug Fixes

    • Restarts now stop safely if launch options cannot be verified, rather than risking loss of compatibility settings.

Merge Risk: 🔵 Low · up to fa9de

A large usage-stream record can interrupt an otherwise valid response. Fix the stream passthrough before relying on this optional Windows feature; the fixture split does not block merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to fa9de

The feature introduces security-sensitive certificate trust and desktop traffic handling. Explicit confirmation, local-session checks, restricted destinations, and fail-closed lifecycle controls substantially constrain exposure. Installed-Windows crash recovery, trust behavior, and native rollback remain insufficiently demonstrated.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The intended traffic scope is the participating desktop application's chatgpt.com connection, but certificate-trust state is shared at the Windows-user boundary rather than owned exclusively by that application. Native credential verification uses that user's Codex login. The inspected design therefore has meaningful user-level trust and credential exposure despite loopback-only listeners; machine-wide trust, cloud IAM, and remote execution authority are not established by this evidence.

Trust Boundaries and Controls

  • observed — Privileged POST operations require a resolved GUI-session principal and trusted loopback ingress. Listener configuration supplies ingress provenance rather than request headers. GUI-session authorization binds the server and browser origins and checks CSRF for unsafe methods; raw administrator credentials are not interchangeable with GUI-session authority.
  • observed — The relay rejects foreign hosts and non-origin request targets, forwards to a fixed upstream origin, and uses manual redirect handling. Native identity activation requires fresh upstream verification, not merely unverified claims read from the local login file.

Resilience and Maintainability Implications

  • observed — Durable connection metadata deliberately preserves the PAC nonce and public ports across runtime restarts. Startup must bind and verify those endpoints before registering launch authority. Restart authorization additionally requires a current in-memory owner and matching generation, so identical persisted endpoints do not alone authorize a replacement runtime to inherit an earlier restart approval.
  • observed — Response correction rechecks identity and activation generation across asynchronous work and refuses output after context invalidation or the safety deadline. The documented dashboard distinguishes withdrawal of correction from unconfirmed native cache refresh; it does not claim that producing an original response proves native cache rollback.

Hardening Proposals

  • proposed — Before release, demonstrate installed-Windows recovery with a desktop retaining cached PAC state: terminate the runtime, occupy either persisted port with an unrelated process, attempt restart, and verify refusal, TLS validation, and native fallback behavior. Also verify uncertain trust removal and withdrawal of corrected native cache state. These are targeted assurance proposals, not findings that those controls currently fail.

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.

🟡 Minor · Fail closed when the active PAC command line is unavailable. · windows.ts:155-156

src/codex/desktop-app/windows.ts:155-156
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Fail closed when the active PAC command line is unavailable.

If a later CIM listing returns an empty CommandLine for a root launched with the managed PAC, the parser drops that field and captureWindowsCompatibilityContext returns {}. 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.

Suggested fix
 return { pid, parentPid, createdAt, executable,
-  ...(encoded ? { commandLine: Buffer.from(encoded, "base64").toString("utf8") } : {}) };
+  ...(encoded !== undefined ? { commandLine: Buffer.from(encoded, "base64").toString("utf8") } : {}) };
   for (const entry of processes.filter(value => !members.has(value.parentPid))) {
+    if (entry.commandLine === "") throw new Error("desktop_compatibility_launch_context_unavailable");
     for (const match of (entry.commandLine ?? "").matchAll(/(?:^|\s)"?--proxy-pac-url=([^"\s]+)"?/g)) {

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.

Maintenance verification for 56d644572d8680cc243f4b1ac6a7f2d92a7ecdf7:

Merged current dev (0328373fb88fe0d019b29ae278e153d7fed4bcc7), preserving this PR's scope. 34 temporary-store, mocked identity/routing, build-probe and snapshot tests passed; typecheck, structure, privacy and file-size gates passed.

Cross-platform CI succeeded for this HEAD; the checkout tree matches the PR HEAD tree. Skipped jobs remain skipped. Local validation used focused tests; the full local suite and test:changed were not run.

Installed Windows lifecycle/PAC ownership checks, the native composer exhaustion-to-independent-provider completion scenario, and independent maintainer review remain required. No installed app or real PAC/trust settings were changed.

Preserve Windows Codex Desktop and macOS ChatGPT Desktop structure ownership, plus upstream JEV ownership; regenerate the structure index.

Validated on Linux/Bun 1.4.0: 329 focused passes, 5 Windows-only skips; 108 upstream regression passes; typecheck, structure, privacy, file-size ratchet, whitespace, and docs build pass.

Keep Draft: independent security review and current installed-Windows end-to-end validation remain required.

Integrated latest dev 10428d0120cbceeff997508a28a7a50c4007f7dc in bfd76c9a50bb856c2699689cbe770718b8baabe4 by a non-force fast-forward update. The remote commit's tree and both parents match the verified local integration.

All 13 merge conflicts retain the compatibility behavior and upstream additions. This includes machine-local compatibility routing, all ten locale catalogs, the Claude page, config/BOM documentation, and native desktop egress documentation. The subsequent credit-opt-in changes also merged and passed the focused quota/config regressions.

Final-tree validation: 362 backend tests passed (5 Windows-only skips), 2,778 GUI tests passed; TypeScript, GUI lint/i18n/build, structure, privacy, file-size, whitespace, and docs build passed (561 pages, 77,830 internal links). The full local backend suite was not run; the PR Verification section records commands and coverage.

Exact-head Cross-platform CI and React Doctor both completed successfully for bfd76c9a. All four Linux shards and the aggregate ci check passed. Full Windows/macOS matrices and packaged desktop shell checks were skipped; they do not prove installed-Windows behavior. CodeRabbit's current-head review completed successfully for 822a4a98 → bfd76c9a with no new actionable comments. The prior 10 inline review threads are resolved; independent security review and installed-Windows lifecycle, composer attachments/IME, natural exhaustion, and completed independent-provider response evidence remain outstanding. No installed app or OS security configuration was changed. No merge or release is requested.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Pass oversized usage-stream records through unchanged.

If the upstream sends a valid SSE record larger than the default 262,144-byte cap, controlledUsageSse throws instead of forwarding it. createUsageControlledFetch turns that into a response-body error. Because relay-listener.ts has already sent the response headers, it destroys the connection, which can truncate the original 200 stream. Keep the cap bounded, but pass the oversized record through raw and resume framing at its delimiter.

Update controlledUsageSse so reaching the record cap switches that record to raw
passthrough instead of throwing or buffering beyond the cap. Forward its
remaining bytes unchanged through the SSE record delimiter, then reset framing
state and resume normal rewriting for subsequent records; keep memory bounded by
the cap.
