Summary

  • Fixes [Bug][Windows] Prompt probe misses Codex App runtime and base prompt source #4458.
  • Reuse the shared Codex runtime resolver for prompt probing and discover Codex App installations below %LOCALAPPDATA%\OpenAI\Codex\bin\<changing-version> on Windows.
  • Preserve the current user PATH in the generated Windows service wrapper so later Codex installations remain visible to the service process.
  • Read the configured root model's base-prompt source from the catalog or model_instructions_file, expose model/source/byte metadata, and label expanded text versus an unexpanded template.
  • Return the base source and failure classification from the existing prompt probe endpoint; keep the current GUI scope unchanged.

Verification

  • OCX_TEST_NO_QUEUE=1 bun test tests/codex-integration/codex-runtime.test.ts tests/codex-integration/codex-prompt-text-probe.test.ts tests/codex-integration/codex-prompt-route.test.ts tests/codex-integration/codex-prompt-base-variants.test.ts tests/service/service.test.ts --timeout 20000 — 377 passed, 4 skipped, 0 failed.
  • bun run typecheck — passed.
  • bun run privacy:scan — passed on the latest commit.
  • git diff --check — passed.
  • Review follow-up: Windows App candidates are ordered by newest directory mtime with a deterministic name tie-break; PATH remains intentionally higher priority than the App fallback; configuration read failures distinguish ENOENT from other errors.
  • Review follow-up 2: preserve ENOENT as program-not-found for a missing fallback command; treat empty or whitespace-only model_instructions_file content as unavailable (override-empty) rather than effective prompt text.
  • Review follow-up 3: bound local prompt-source reads at 8 MiB; oversized config/catalog/override sources return a source-specific unavailable reason before file content is loaded.
  • Review follow-up 4: open bounded config/catalog/override sources once, reject non-regular files, prefer a concrete runtime failure over fallback ENOENT, and strip embedded quotes from the runtime-expanded Windows PATH value.
  • Review follow-up 5: open prompt sources nonblockingly before regular-file checks, keep malformed catalog rows unavailable instead of throwing, and report the concrete failed runtime command.
  • Review follow-up 6: omit raw Codex process diagnostics from the management response while preserving the stable failure kind and command for diagnosis.
  • Review follow-up 7: add a POSIX-only FIFO regression proving a non-writer prompt source is rejected without blocking; Windows skips this platform-specific case.
  • Scope boundary: profile/root instructions precedence and GUI rendering of the template representation remain separate follow-up work; this PR does not claim those paths.
  • The branch was rebased onto dev at 4a84ca22. The repository pre-push check was started with the project Bun runtime. Typecheck and GUI-change lint passed; the full test stage reproduced unrelated OAuth, composed Codex acceptance, catalog-sync, and management/API failures before it was stopped, so no full-suite pass is claimed.
  • The earlier bun run test:changed run against the previous base ended with exit 124 after 8,692 passed and 172 failures across broad unrelated provider/network, account-pool, management/API, and lab suites. The candidate prompt-probe and runtime tests passed in that run; this is historical local evidence, not latest-dev CI evidence, and it was not rerun after the rebase.
  • No paid model request was made. No GUI changes are included, so no GUI screenshot is required.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Review gate status

The latest head includes upstream dev at 94063d0 and is mergeable. The focused verification set now passes 377 tests with 4 platform-specific skips; the runtime memo fix and its regression coverage are included in 13fdd2f. The fork PR's Cross-platform CI run 34756563853 is action_required with no jobs, so external-workflow approval is still pending; the all-CI checklist box remains intentionally unticked. Enforce-target, hygiene, label, and CodeRabbit checks pass, and all Codex/CodeRabbit review threads are resolved. No GUI files or paid model requests are involved. Maintainer approval and merge remain separate steps.

Review readiness checklist

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

  • All CI tests are green on my local testing.

  • I pushed my PR to the latest dev commit.

  • I resolved all correct Codex and CodeRabbit findings.

  • My PR is ready for review.

📝 Walkthrough

Walkthrough

The prompt probe now loads base prompt metadata, discovers installed Codex runtimes, returns structured execution failures, and preserves base data across failures. The Windows service wrapper preserves the runtime PATH, and the management route removes raw process diagnostics.

Changes

Codex prompt runtime flow

Layer / File(s) Summary
Runtime discovery and PATH wiring
src/codex/runtime.ts, src/service.ts, tests/codex-integration/codex-runtime.test.ts, tests/service/service.test.ts
Runtime selection discovers Codex App installations on Windows and fixed installed locations on Unix-like systems. The Windows wrapper appends the current %PATH% to the captured install-time path.
Base prompt metadata
src/codex/catalog/parsing.ts, src/codex/prompt-text-probe.ts, tests/codex-integration/codex-prompt-text-probe.test.ts
The probe reads configured instruction sources and catalog data. Results include source, model, representation, availability, size-limit, and layer metadata.
Structured probe execution
src/codex/prompt-text-probe.ts, tests/codex-integration/codex-prompt-text-probe.test.ts
Probe execution uses resolved Codex invocations, captures stderr, classifies runtime, process, and output failures, and propagates structured results through shared flights.
Sanitized management response
src/server/management/codex-prompt-routes.ts, tests/codex-integration/codex-prompt-route.test.ts
The management route returns failure kind and command metadata without raw process diagnostics. The route test verifies that stderr content is omitted.

Explanation

Most changes are connected to Issue #4458. The optional configuration-text handling in src/codex/catalog/parsing.ts supports prompt catalog resolution, and the runtime, service, probe, route, and test changes support the linked objectives. However, the reviewed head removes the gpt-5.3-codex-spark Fast-tier exclusion in src/codex/catalog/parsing.ts. That change can re-enable unsupported priority tier metadata. The exclusion is unrelated to Windows runtime discovery or prompt-source probing, and it introduces a regression outside the linked issue scope.

설명

이 PR은 이슈 #4458을 겨냥합니다. Windows에서 Codex App이 설치한 실행 파일은 %LOCALAPPDATA%\OpenAI\Codex\bin\<버전>\codex.exe처럼 버전 폴더 이름만 바뀌는 경로에 있습니다. 지금 dev의 프롬프트 프로브는 예전에 고정 POSIX 후보만 보거나, 공용 런타임 해석을 쓰지 않아 App 설치를 놓치고 Codex program not found가 날 수 있습니다. 또한 prompt_debug 출력에는 base instructions가 없어서, 선택 모델의 카탈로그/model_instructions_file 쪽 base 원문을 프로브 응답에 실을 수 없었습니다.

이번 브랜치는 (1) resolveCodexRuntime에 source installed 후보를 넣어 위 App 경로를 읽고, (2) 프롬프트 프로브가 그 공용 런타임을 쓰며 base 텍스트·모델·소스·바이트·expanded/template 구분·실패 분류를 기존 엔드포인트에 추가하고, (3) Windows 서비스 래퍼가 설치 시점 PATH만 고정하지 않고 현재 사용자 PATH를 이어받아 이후 Codex 설치도 보이게 합니다. GUI 화면은 그대로 두고 API 메타데이터만 넓힙니다. Draft이고, 본문도 full-suite 초록을 주장하지 않습니다. types/config 분할과 무관합니다.

라인 src/codex/runtime.ts:413 - readdirSync 결과를 정렬하지 않습니다. bin 아래에 버전 폴더가 여러 개면 파일시스템 순서로 첫 유효 codex.exe를 고릅니다. PATH가 비어 App만 있을 때 오래된 빌드가 잡힐 수 있으니, mtime이나 버전 비교로 고르는 편이 안전합니다.

라인 src/codex/runtime.ts:643 - installed 후보는 path 다음입니다. PATH에 죽은/옛 codex가 있으면 App의 새 설치보다 PATH가 이깁니다. 서비스 PATH 상속 수정과 맞물리면 대부분 괜찮지만, “App 설치를 반드시 선호”가 목표면 순서를 명시적으로 정해야 합니다. 667행 주석도 아직 path → fallback만 말하고 installed를 안 적습니다.

라인 src/codex/prompt-text-probe.ts: readBasePrompt - config.toml을 못 읽어도 reason이 model-not-selected입니다. 설정 파일 자체가 없을 때와 모델 키만 비어 있을 때가 같은 코드로 보입니다. 분류를 나누면 Windows 진단이 덜 헷갈립니다.

경로 tests/codex-integration/codex-prompt-text-probe.test.ts · codex-runtime.test.ts · service.test.ts - base 카탈로그 읽기, LOCALAPPDATA 후보, 서비스 PATH 상속을 각각 고정합니다. 범위는 이슈와 맞습니다.

메인테이너의 판단이 필요한 지점

  • 여러 Codex App 버전 디렉터리가 있을 때 최신 선택 규칙(mtime vs 버전 문자열)
  • PATH 유효 엔트리보다 installed를 올릴지, 지금처럼 PATH 우선을 유지할지
  • Draft 게이트(로컬 CI·CodeRabbit·ready 체크)를 닫기 전에 문서/릴리스 노트 갱신이 필요한지

너의 추천
Draft 유지하세요. 버전 폴더 정렬(또는 최신 선택)과 reason 분류만 다듬은 뒤, 본문이 적은 대상 테스트·typecheck가 dev 기준으로 다시 초록인지 확인하고 Ready로 올리세요. #4458 방향은 맞습니다. 지금 합치지 마세요.

Addressed in e3fb342 and the preceding review-fix commit:

  • Windows Codex App candidates are ordered by newest install-directory mtime, with a deterministic directory-name tie-break, and a regression test covers multiple installs.
  • The existing priority remains explicit: environment/configured/shim/PATH candidates win; the App directory is the fallback when those sources are unavailable.
  • Prompt configuration read failures now classify the actual filesystem error (ENOENT as config-not-found, other read failures as config-unreadable), with coverage for missing, unreadable, and unselected configuration states.

Focused verification on the latest head: 364 passed, 3 skipped, 0 failed; typecheck, privacy scan, and diff check passed. The full local suite still has unrelated failures, so this PR remains Draft and makes no full-suite claim.

346-350: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Classify the missing fallback command as program-not-found.

When no earlier runtime candidate validates, resolveCodexRuntimeUncached probes the bare codex fallback at src/codex/runtime.ts:655. probeVersion invokes the bound node:child_process execFileSync; a missing codex executable raises ENOENT, but the catch block converts it to failed --version (...) at lines 353-357. classifyRuntimeFailure then maps that text to execution-failed at src/codex/prompt-text-probe.ts:346-350.

Preserve the ENOENT classification from probeVersion, or detect it before the failed --version branch. Add a regression test that leaves setPromptTextProbeCommandForTests unset, isolates runtime discovery so the fallback is the only candidate, and expects program-not-found. The existing test injects an explicit missing binary at tests/codex-integration/codex-prompt-text-probe.test.ts:262; it exercises runProbe directly and does not cover fallback resolution.

  • Preserve ENOENT from the runtime version probe and classify a missing fallback command as program-not-found.
  • Treat empty or whitespace-only model_instructions_file content as unavailable (override-empty) instead of effective prompt text.
  • Added focused regressions; the 5-file focused set is now 366 passed, 3 skipped, 0 failed.

@S0RYUASUKA I reviewed the current follow-up.

I found no blocking correctness issue.

src/codex/prompt-text-probe.ts, Lines 158-186, now opens prompt sources with O_NONBLOCK, validates fstatSync(descriptor).isFile() before reading, and retains the 8 MiB plus one byte limit. This prevents a POSIX FIFO from blocking the management request.

tests/codex-integration/codex-prompt-text-probe.test.ts, Lines 481-511, now covers the no-writer FIFO case and expects override-unreadable.

src/codex/runtime.ts, Lines 417-447, orders Windows Codex App directories by descending mtime with a deterministic name tie-break. Lines 654-741 retain the explicit priority: environment, configured, shim, PATH, installed, then fallback.

src/server/management/codex-prompt-routes.ts, Lines 329-337, returns only the failure kind and command. It does not return raw process diagnostics.

I performed static inspection only. I did not execute repository code or tests.

@S0RYUASUKA I found one regression.

P1 — Restore the Fast-tier exclusion for gpt-5.3-codex-spark.

In src/codex/catalog/parsing.ts, Line 420, this PR removes NO_FAST_TIER_NATIVE_SLUGS and the early return in normalizeServiceTiers().

Before this change, gpt-5.3-codex-spark had these fields removed:

  • service_tier
  • service_tiers
  • default_service_tier
  • additional_speed_tiers

The removed code states that this model does not support the Fast (priority) tier. Without the exclusion, a catalog row that contains Fast-tier metadata reaches the Codex UI again. Codex can then offer or send an unsupported priority tier.

This behavior change is outside the stated Windows prompt-probe scope. Restore the exclusion in this PR. If Fast-tier support is now confirmed for this model, add a focused regression that proves the published catalog and the runtime request both accept the tier.

I performed static inspection only. I did not execute repository code or tests.

Superseded by dfa0e2f, which carries this work onto dev.

Your change is in that commit with a Co-authored-by trailer naming you in a branch commit, so it survives the squash merge and reaches the contributor graph.

Why it was carried rather than merged directly: the same lane also had to fix the stale persisted CLI version that was stripping max and ultra from the reasoning ladder, and both fixes land in src/codex/runtime.ts. Rather than merge two branches into the same resolver in sequence, the runtime source resolution and your Windows base-prompt-source read were done together, and the probe moved onto the shared resolver in the process.

Issue #4458 is deliberately still open: the carried work fixes the runtime discovery and the program-not-found case, but not the published base prompt source. If you want to take that remaining half, it is yours.

Thank you for the fix.
