Summary

Upstream submission: lidge-jun/opencodex#5829, opened as a draft against dev. This source PR stays available with its original discussion and commit history; it was not force-pushed, merged or closed during the carry.

Use native codex queue as an on-demand, limited alternate input path when the desktop composer is blocked but an existing thread has an otherwise usable, authorized route. It does not repair the composer/model picker, switch a gpt-reserve thread, reset quota, or override provider authorization and main-account admission. App/CLI updates can change compatibility.

Integration and lifecycle

  • Send only the explicit thread UUID/exact name and literal text; latest-rollout discovery is a deliberate heuristic, not the foreground conversation. Preserve the effective CODEX_HOME, OPENCODEX_HOME, working directory and configuration files.
  • Reuse the native queue and the thread's existing provider. No TLS/Statsig/app patch, authless change, new router, account selector, background listener, quota monitor, restart or automatic resend is introduced.
  • No invocation means no helper activity. When quota is available, a deliberate invocation still queues one normal message. There is no persistent on/off setting. Stopping future invocations is not cancellation of items already accepted by Codex.
  • Queue acceptance is not execution/completion. Open/resume an unloaded thread without sending the prompt again. Remote provider URLs are not automatic remote app-server discovery.
  • These are repository-checkout scripts, not an installed ocx queue command or dashboard control; npm packaging is unchanged.

Upstream preparation and bot follow-up

The latest source commit is 9efc3c689fea00f7799ff8793f5890a2768c8ee0, after the prior CodeRabbit test/documentation follow-ups at eaac13e.

The remaining executable-discovery finding was corrected in both Bash and PowerShell: empty and relative PATH entries are skipped before any CLI probe. Explicit trusted local pinning is still allowed. New regressions cover dry-run and submission paths plus the explicit-pin control. The finding has an individual evidence-bearing reply and is resolved; this is not an independent security approval.

The clean upstream head is 3406b0bc2a8ae677dd46697445220c2a81679a37, one commit on upstream dev at 0f4c8d4a0f4f2873a72dad6bf0e241529491c277. Its six-file diff retains current upstream navigation/internal-link validation and adds guide clarification about pre-dispatch diagnosis, unchanged admission guards and CLI trust. The identical wrapper/test blobs are carried, with CodeRabbit's material contributions credited by Co-authored-by.

The upstream description consolidates lidge-jun#4878, lidge-jun#5694 and lidge-jun#5797, while distinguishing the prevention work in lidge-jun#5743/lidge-jun#5748 from the separate interception proposal lidge-jun#5733. It does not automatically close or reopen those reports.

Verification

Current source head, 9efc3c6

  • PASS: Codex queue helpers run 36102691829, all three hosted jobs: Windows PowerShell 5.1/7, macOS system Bash, Linux.
  • PASS locally: CODEX_QUEUE_TEST_SHELLS=bash node --test scripts/codex-queue.test.mjs — 45 passed, 0 failed, 0 skipped, Node 22.16.0 / Bash 5.2.37 / Linux.
  • New four-case PATH regression set: parent helper has three expected failures and one passing explicit-pin control; corrected helper passes all four. Fake CLIs only.
  • Bash/Node syntax and whitespace checks pass in the partial workspace. File blob hashes match the published source. The upstream sidebar adaptation was separately checked against its base file and its navigation contract.
  • Source-head React Doctor run 36102691853 succeeded. General source Cross-platform CI 36102691850 was still in progress at the last observation.

These tests use temporary homes and fake native CLIs. They do not prove live OpenCodex/provider routing. Source-head success also does not certify the newly rebased upstream commit; lidge-jun#5829 tracks its own exact-head checks.

Outstanding verification

Local full bun run typecheck, bun run test, bun run privacy:scan, bun run prepush and Astro install/build were not available: no Bun, PowerShell or complete checkout, and container DNS prevented dependency retrieval. No pass is claimed for those commands.

The read-only workflow has been technically inspected (normal PR/push, hosted runners, minimum permissions, pinned checkout, no persisted credentials/dependencies/secrets/live models), but independent maintainer security review remains necessary. Matching Desktop → OpenCodex → intended provider completion, unloaded/approval behavior and remote-control continuity remain unverified. The original Desktop 26.917.9434.0 probe reported acceptance only.

Historical 24/32/33-test and earlier CI results remain in the commit/review history; they are superseded by the current scoped evidence above, not presented as current-head results.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Current source-head dedicated helper checks passed on Windows, macOS and Linux.
  • Upstream draft published with related-report scope, validation limits and attribution.
  • Independent maintainer security review completed.
  • Remaining required exact-head repository/documentation checks completed.
  • Matching live Desktop/OpenCodex provider dispatch and remote-control behavior verified.

📝 Walkthrough

Walkthrough

Adds Bash and PowerShell helpers to send messages to Codex threads with codex queue. Adds a guide describing these helpers and other CLI options for use when the desktop composer is blocked by a client-side usage gate.

Changes

Composer usage-gate fallback

Layer / File(s) Summary
Cross-platform queue helpers
scripts/codex-queue.ps1, scripts/codex-queue.sh
Both scripts accept a message and an optional thread ID. When no thread ID is supplied, they select the newest rollout file and extract its UUID. They locate a Codex executable, invoke codex queue, and return or propagate its exit status.
Documented fallback options
docs-site/src/content/docs/guides/composer-usage-gate-fallback.md
The guide describes codex queue, codex exec, and codex resume, explains thread ID resolution and quota behavior, and covers remote control and the helper scripts.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~12 minutes

Change: Other

Suggested reviewers: lidge-jun

Merge Risk: 🟡 Moderate · up to fbda9

The new fallback helpers can fail or send a message to the wrong conversation in the following cases:

  • Codex uses a custom home directory.
  • An older codex is on PATH.
  • The user has many saved sessions.

The guide also slightly misdescribes which session resume --last picks. These are contained to the new scripts and docs, but they should be fixed before merge.

Implemented the focused hardening in 45ff4f9; all four GitHub file blobs match the locally tested versions.

Assessment: native codex queue is a reasonable least-invasive fallback for an otherwise usable thread when preserving desktop authentication is important. It is not a complete composer/model-picker fix. In particular, a thread still configured for gpt-reserve is not rerouted by queueing, and server quotas/authorization remain unchanged.

The revision addresses the valid review findings: effective CODEX_HOME, supported standalone layouts, bundled-before-PATH capability selection, safe global latest-file selection without ls/head, Bash end-of-options, and resume --last working-directory scope. It additionally removes implicit target selection, adds preview/explicit binary pinning, preserves literal native arguments, and avoids automatic retry.

The most important documentation correction is acceptance versus dispatch: the inspected upstream run_session_queue_action_with_app_server sends thread/queue/add only, while dispatch_if_idle/wake_if_loaded do not load an absent thread. An accepted message can remain pending. The guide now says to inspect/open/resume the same conversation without submitting the prompt again. No automatic force-start or second-server workaround was introduced.

Executed here: 24/24 offline Bash wrapper tests with Node 22.16.0/Bash 5.2, bash -n, node --check, and diff whitespace validation. The tests use fake native CLIs, not an account/model. Windows PowerShell, macOS, actual Desktop/provider completion and remote-control continuity remain unverified. Full Bun checks/privacy/prepush and docs build were unavailable locally and remain explicitly unchecked in the PR description. At the latest observation, Cross-platform CI was in progress; this comment is not a merge approval or an assertion that all checks are green.

I have left the existing review threads available for reviewer re-evaluation rather than treating the new source changes as proof of unexecuted platform/runtime coverage.

Document the on-demand lifecycle, ordinary-usage behavior, existing routing
ownership, and repository-only distribution. Preserve PowerShell's current
filesystem directory for native CLI children and redact dry-run selection
unless explicitly requested in a local terminal. Add sidebar discovery and
an offline Windows/macOS/Linux wrapper workflow with read-only permissions.

Validation: 32 Linux Bash offline tests, bash -n, Node syntax checks, YAML
static security checks, and diff whitespace checks. Windows/macOS, live
Desktop dispatch, and full Bun/docs validation remain separate checks.

The new Windows CI exposed a relative CODEX_HOME lookup failure in Windows
PowerShell 5.1. Anchor filesystem discovery to the shell location while
preserving the environment passed to Codex.

Correct the offline harness to compare native canonical paths (8.3 aliases
are not different directories) and propagate the script's LASTEXITCODE
through the outer PowerShell -EncodedCommand launcher. No tests are skipped.

Validation: 32 Linux offline tests and syntax checks pass. Windows and macOS
will be verified by the required-shell workflow for this exact head.
Address the new bot finding without changing bundle-first or explicit-pin
semantics. Inspect PATH entries in order and reject an obsolete candidate
before trying the next one. Preserve whitespace in paths.

Add an offline regression with two competing PATH executables. Linux suite:
33 passed, 0 failed; bash and Node syntax plus whitespace checks pass.

Follow-up integration/lifecycle review completed for b8cfba1.

Assessment: preserve the native queue + existing OpenCodex routing boundary. This is a deliberately narrow on-demand fallback, not a fully packaged/dashboard-integrated feature or a model-picker repair. A persistent toggle would add state without controlling any background behavior, because no helper runs until explicitly invoked. Normal usage availability does not suppress a deliberate invocation: it queues one ordinary message. Stopping future invocations does not cancel already accepted queue items.

Changes in this follow-up: c938967 documents integration/on-off/normal-usage behavior, redacts default diagnostics, preserves PowerShell working-directory context, adds guide discovery, and wires a dedicated offline platform workflow. 59bf48c fixes the Windows PowerShell relative-home failure exposed by that CI and corrects the harness's 8.3-path/outer-launcher exit-code assertions. b8cfba1 fixes the newly reported later-PATH CLI discovery defect and adds its regression.

Observed verification: local Linux 33/33 offline tests; exact-head Codex queue helpers workflow 35957767065 completed successfully on Linux, macOS system Bash and Windows PowerShell 5.1/7. React Doctor 35957767006 succeeded. These use fake native CLIs and temporary configuration files, not real account/model traffic.

Bot handling: reviewed the 15 known inline threads, including follow-up findings. Five previously resolved Devin threads remain addressed; nine additional code/documentation/metadata threads have individual evidence-bearing replies and are resolved. The remaining pre-merge verification thread PRRT_kwDOTmCbas6lcVt7 has an explicit status reply and stays open. CodeRabbit independently confirmed the four original findings after the replies. No blanket bot approval or silent dismissal was used.

Outstanding: separate latest-head Cross-platform CI 35957766946 was queued at the last observation; local complete Bun/prepush/docs checks were unavailable; live Desktop→OpenCodex→provider completion and remote-control continuity remain unverified; the new read-only workflow still needs independent maintainer security review. No merge/approval, user-PC configuration change, daemon restart, quota manipulation or real model request was performed.

Address the remaining CodeRabbit finding in #619 before upstream submission.
Both Bash and PowerShell inspect PATH components before resolving candidates,
ignore empty/relative entries, and retain authoritative explicit local pinning.
Existing bundle-first discovery and configured Codex homes are unchanged.

Add harmless fake-CLI regressions for empty, dot and relative PATH entries in

Closing this source-side mirror. The active published contribution contains byte-identical workflow and helper implementations: .github/workflows/codex-queue-helpers.yml (380d27ba93d0dbfb202ebbdd3ad13f0028f3e555), scripts/codex-queue.ps1 (7847b315af79b008ab8471aa951488629c3fa481), scripts/codex-queue.sh (7f9eb1d2d4b02bfc7e27ee0f4a88638743827d28), and scripts/codex-queue.test.mjs (268aecc43eb398c292ef6da6621d94a409b4ddc8). The guide and navigation entry were also carried, with the guide expanded to clarify blocked-layer and executable-selection limits. Comparing the two guide blobs found no unique remaining implementation or instruction that needs a separate review lane. This PR's branch and discussion remain available as history.

Carry the focused implementation from #619 through
9efc3c6 onto current upstream dev.
Original review and commit history remain intact on the source branch.

Add explicit-target Bash/PowerShell wrappers, private dry-run diagnostics,
literal native arguments, native queue capability checks, and offline CI.
Automatic PATH discovery skips empty/relative entries; explicit local
pinning remains supported. No routing, authentication, quota, runtime,
packaging, or application-file changes are introduced.

Document the pre-dispatch boundary, ordinary-usage/on-off behavior,
queue acceptance versus completion, and unchanged main-account admission.
Retain the upstream sidebar and internal-link validation changes.

Related reports: lidge-jun#4878, lidge-jun#5694, lidge-jun#5797.
This is a limited alternate input path, not complete issue closure,
Reserve rerouting, a composer/model-picker repair, or a quota reset.

Validation: 45/45 local Linux offline wrapper tests, 4-case red/green PATH
regressions, Bash/Node syntax, sidebar rebase contract, and whitespace checks.
Identical wrapper/test blobs passed source-branch three-platform workflow
36102691829 at 9efc3c6; that result does not certify this new upstream head.
Full Bun/prepush/Astro and live Desktop/provider/remote tests remain pending.
