Summary

  • Selected-installation discovery probed proof-captured PATH and candidate paths with ordinary exists/read APIs, which can trigger SMB/UNC network access on Windows and leak NTLM material; discovery must validate non-local/reparse-backed paths before any filesystem I/O.
  • Route candidate discovery through the Windows held-handle inspector: deriveCodexCliInstallationInput is now asynchronous and resolves existence/marker checks via inspectWindowsInstallationFiles (metadata-only probes for existence, bounded prefix reads for wrapper detection) while preserving PATH/PATHEXT resolution ordering (src/codex/cli-installation-targets.ts, src/cli/codex-cli-update.ts).
  • Add a metadataOnly request option to inspectWindowsInstallationFiles so existence checks validate and hold a path without reading its contents (src/codex/windows-installation-files.ts), and document the hardened discovery guarantee in structure/runtime.md.

Verification

  • bun test tests/codex-integration/codex-cli-installation-targets.test.ts tests/codex-integration/codex-cli-windows-installation-files.test.ts tests/cli/cli-codex-cli-update.test.ts — 47 tests pass.
  • bun run typecheck — clean.

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.

Summary by CodeRabbit

  • Improvements

    • Improved Codex CLI installation detection by securely validating candidate paths before verification.
    • Prevented installation discovery from triggering unintended network filesystem access.
    • Improved handling of unreadable or inaccessible installation candidates so they are reported as unavailable rather than treated as absent.
    • Improved inspection of large installation files by limiting reads when full contents are unnecessary, while preserving verification behavior.
  • Documentation

    • Updated runtime documentation to describe the enhanced installation observation and path-safety behavior.

📝 Walkthrough

Walkthrough

Installation target derivation now performs asynchronous filesystem checks through Windows installation inspection. Windows inspection supports metadata-only and bounded prefix reads. The CLI update path and tests now await derivation results. Candidate selection and refusal outcomes remain unchanged.

Changes

Installation discovery and observation

Layer / File(s) Summary
Windows file observation modes
src/codex/windows-installation-files.ts, tests/codex-integration/codex-cli-windows-installation-files.test.ts
WindowsInstallationFileRequest now accepts metadataOnly and prefixOnly. Metadata-only requests return identity data without reading or hashing. Prefix-only requests read at most maxBytes and omit the digest for truncated reads. Native tests cover both modes.
Asynchronous installation derivation
src/codex/cli-installation-targets.ts, src/cli/codex-cli-update.ts, structure/runtime.md
Installation checks now accept promises and await candidate checks. Default checks use inspectWindowsInstallationFiles. The CLI update path awaits derivation. Runtime documentation describes the updated discovery behavior.
Derivation flow validation
tests/codex-integration/codex-cli-installation-targets.test.ts, tests/cli/cli-codex-cli-update.test.ts
Existing derivation tests now await results. New tests confirm that refused PATH probes stop scanning and that unreadable wrapper probes return candidate_unavailable rather than marker absence.

Merge Risk: ⚪ Minimal · up to fa679

Windows discovery now uses bounded, refusal-aware inspection without selecting unsafe later candidates, and callers await the asynchronous result. No actionable merge-blocking risk remains.

이 PR은 Windows에서 “지금 쓰는 Codex CLI 설치”를 찾을 때, 예전처럼 existsSync나 일반 파일 읽기로 PATH·후보 경로를 두드리면 안 된다는 고침입니다. 그런 호출은 SMB/UNC 같은 네트워크 경로에 닿을 수 있고, 그때 NTLM 정보가 새어 나갈 수 있습니다. 그래서 후보를 찾는 일도 이미 있는 held-handle 검사기(inspectWindowsInstallationFiles)로 보냅니다. 있는지 볼 때는 metadataOnly로 내용 없이 경로만 잡고, 래퍼(.cmd)인지 볼 때는 앞부분만 읽습니다. deriveCodexCliInstallationInput은 이제 async이고, 업데이트 CLI 한곳도 await로 맞춰 두었습니다. structure/runtime.md에 “발견도 최종 관찰과 같은 로컬·리파스 거절 경로를 탄다”고 적어 두었습니다. base는 dev입니다. draft이고, 같은 주제의 다른 열린 PR은 보이지 않습니다. types/config 분할과는 무관합니다.

라인 src/cli/codex-cli-update.ts CodexCliUpdateCommandDeps.deriveInstallationInput - 구현은 await derive(...)인데, deps 타입은 아직 동기 반환(CodexCliInstallationTargetDerivation)입니다. 테스트 주입은 await가 일반 값도 받아서 돌아가지만, 타입과 실제가 어긋납니다. Promise<...>로 맞추는 편이 좋습니다.

라인 src/codex/cli-installation-targets.ts fileContains / SHIM_PROBE_BYTES - 주석은 “앞부분만 읽는 prefix probe”인데, inspector는 파일 전체가 maxBytes(8KiB)보다 크면 size-limit로 거절합니다. 예전 readSync 앞 8KiB와 다릅니다. 지금 OpenCodex .cmd 래퍼는 보통 그보다 작아서 당장 깨지진 않을 가능성이 큽니다. 다만 큰 .cmd면 마커를 못 보고, 우리 래퍼를 npm 아티팩트로 잘못 고를 수 있습니다.

라인 tests/codex-integration/codex-cli-windows-installation-files.test.ts - metadataOnly 옵션·maxBytes: 0 존재 확인·크기 제한 건너뛰기 회귀가 없습니다. 이번 보안 고침의 핵심 API인데, targets 테스트는 가짜 exists/fileContains만 쓰고 기본 경로(inspector)는 안 돕니다.

라인 src/codex/cli-installation-targets.ts safeRead - 후보마다 import("./windows-installation-files")와 FFI 열기를 반복합니다. PATH가 길고 앞쪽이 다 빗나가면 느려질 수 있습니다. 동작 문제는 아니고 비용 이야기입니다.

메인테이너의 판단이 필요한 지점
metadataOnly/maxBytes: 0 테스트를 이 PR에 넣고 올릴지, draft 체크리스트·CI를 먼저 채울지. 래퍼 인식은 “전체가 8KiB 이하” 전제를 문서·테스트로 못 박을지, 아니면 inspector에 진짜 prefix-read 모드를 후속으로 둘지. deps 타입을 이 커밋에서 고칠지도 정하면 됩니다.

너의 추천
방향은 맞고 base dev에 두는 것도 맞습니다. 머지 전에 (1) deriveInstallationInput deps를 Promise로 맞추고, (2) metadataOnly 존재 확인·거절 경로 테스트를 최소한 넣는 쪽을 권합니다. 큰 .cmd prefix 문제는 지금 래퍼 크기면 막을 수 있으면, 주석/테스트를 “8KiB 초과면 래퍼로 안 본다”로 명시해 두면 나중에 덜 헷갈립니다. 무효·중복으로 닫을 다른 열린 PR은 없습니다.

🟡 Minor · Return a Promise from the dependency contract. · codex-cli-update.ts:34

src/cli/codex-cli-update.ts:34
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Return a Promise from the dependency contract.

deriveCodexCliInstallationInput now returns Promise&lt;CodexCliInstallationTargetDerivation&gt;, but this dependency still declares a synchronous callback. In strict TypeScript, callers cannot inject the canonical derive function or an asynchronous fake into deriveInstallationInput.

Change the callback return type to Promise&lt;CodexCliInstallationTargetDerivation&gt;. Update injected fakes to async functions.

Based on learnings, an asynchronous dependency must preserve its Promise signature. As per coding guidelines, src/ uses strict TypeScript.

Wrapper detection now reads a bounded prefix through the already held handle instead of refusing files larger than SHIM_PROBE_BYTES, and an inspection refusal propagates as unavailable rather than marker absence. Also covers metadataOnly with maxBytes 0 and returns a Promise from the deriveInstallationInput dependency contract.

Consolidated into #5515 in native Stack #5518.

Source head: fa679396cd0ab5bea0d5bb67fee192bdd3424b06. Replacement head: 1cc3b332c09a7a35f9d760ca82ff719f3bbfb75a.

Superseded by #5515 at 1cc3b33. All 3 unique non-merge contribution commit(s) from this PR head fa67939 are carried with verified patch equivalence and cherry-pick provenance: 13565b3 -> 92ec735; 71ad231 -> f1cfa8b; fa67939 -> 2017617. Subsequent code/test moves were checked and preserve the contribution. This closes a duplicate source in favor of the existing open stack; it does not claim the replacement has landed or passed release gates. Exact-head cross-platform checks and required independent review remain incomplete.

Closing this duplicate standalone review entry at the author's request after verifying migration. This is not a merge or release claim; remaining integration checks and reviews are tracked on the draft replacement. Original branches are retained.

* fix(service): combine startup ownership, token binding, and slot retention

Carries #5512 by @luvs01 (head a12b2ad), which
consolidates #5477, #5306 and #5357:

- bind the service API token to its owning state, canonicalize qualified-localhost
  binds, and carry WSL ownership state honestly (#5477);
- take a fresh task listing for the second startup ownership decision (#5306);
- retain workflow slots for streaming turns (#5357);
- own server-auth fixture lifetime and project a current-schema config for it.

Squashed from the PR's own diff (origin/dev...a12b2ad) onto current dev.

* fix(server): self-heal a replaced package tree via drain-and-restart

Carries #5513 by @luvs01 (head 4d168f1), which
consolidates #5393 and its scheduler follow-up: detect a replaced installed package
tree, degrade health honestly, and drive a timer-driven, retryable drain-and-restart
whose verify step is deferred past scheduler re-entry. The guard factory lives in
src/server/index/package-tree-guard.ts.

Squashed from the PR's own diff (a12b2ad...4d168f1) onto the #5512 carry.

* fix(security): combine install discovery, credential, and transport hardening

Carries #5515 by @luvs01 (head 843f299), which
consolidates #5359, #5285 and #5322:

- keep selected Codex installation discovery off network filesystems, probe
  oversized wrappers through a held-handle prefix read, and stop a PATH scan at a
  refused probe (#5359);
- exclude npm candidates inside the launch directory subtree (#5285);
- refuse plaintext remote hub origins, fail closed on POSIX chmod for credential
  files, and skip the frame-log write when descriptor hardening fails (#5322).

Squashed from the PR's own diff (origin/dev...843f299) onto the chain carry.
Integration: structure/runtime.md wording reflowed by two lines so the combined
service and security stacks stay within the 600-line structure budget.

* fix(security): combine management-auth and boundary hardening

Carries #5516 by @luvs01 (head 245d542), which
consolidates #5326, #5312, #5363 and #5317:

- harden pairing redemption, agent roster intake, and SOCKS5 decoding (#5326);
- guard gh resolution, anchor the grok managed-region fences to whole lines, and
  bound provider-controlled text (#5312);
- harden management-auth admission and provenance (#5363);
- bound the /healthz version before it reaches diagnostics (#5317).

Squashed from the PR's own diff (843f299...245d542) onto the #5515 carry.
Integration: both stacks rewrote the shared server-auth test fixtures. The carry
keeps the #5512 current-schema fixture projection and config helper (including
its 4 KiB boundary case) and adds this PR's Aside sync capability assertions.

- stage Qoder and CodeBuddy system prompts in private files instead of
  child-process argv, with exclusive creation and owned cleanup (#5315);
- bound upstream error bodies and resolve account-scoped transports (Copilot,
  Devin) from the same OAuth snapshot as the bearer (#5336).

* feat(codebuddy): integrate capture-only tools with private prompt staging

Carries #5582 by @luvs01 (head 3061ef9), which
integrates the capture-only CodeBuddy tool bridge from #5148 by @mdwsk88 with the
private prompt staging from #5517. Requests with a tool catalog advertise only the
allowed tools through an isolated MCP server that captures calls without executing
them; the client keeps approval, sandboxing and execution. Pre-init, undeclared,
excessive or incomplete calls are rejected, streamed malformed tool arguments are
suppressed, bridge staging failures return a fixed message, and an opt-in live
acceptance harness is included. Design context: #5146.

Carries #5252 by @luvs01 (head 779ef91): give the
hub catalog body read an overall deadline (24x the inactivity window, capped at
120 s) on top of the inactivity window, and release refused, HTTP-error and 304
bodies without awaiting their cancellation.

* fix(grok): reserve model aliases only when the written config stays valid

Reimplements #5281 by @luvs01. A user sub-table such as [model.ocx-mine.extra]
only creates an implicit parent, so it no longer forces the generated table to a
suffixed alias. The alias choice is now checked against the bytes actually
written: the unsuffixed alias is used only when the final config (after
model-reference rewriting) parses; otherwise the conservative choice that also
reserves deeper headers is used, and a valid user file for which neither choice
parses is refused without writing. Malformed user TOML keeps the previous
conservative reservation.

The original change reserved only exact two-segment headers, which could emit a
duplicate [model.x] table when the user defines model.x through dotted keys.

* fix(codex-auth): scope Codex OAuth cancellation to the originating flow

Reimplements #4923 by @luvs01 on the current login-state layout (in-flight
controllers moved to src/oauth/login-flow-state.ts in #5220). Cancelling a Codex
login was keyed only by provider, so a stale modal posting an old flowId could
abort a newer attempt, and a cancel without a flowId expired every pending flow.

- Each in-flight controller records the flowId that started it; a cancel whose
  flowId does not match the active attempt is refused before anything aborts.
- POST /api/codex-auth/login/cancel requires a non-empty flowId, rejects unknown
  or non-pending flows with 400 without touching any row, and expires only that
  flow. Provider-wide cancellation through /api/oauth/login/cancel is unchanged.
- ocx account cancel requires --flow for Codex providers and sends no request
  without it.

The dashboard's 409 recovery keeps its code; its ownerless cancel is now refused,
so it ends in the existing "already in progress" message instead of superseding a
flow it does not own.

* fix(socks5): bound compressed event streams by expansion, not total size

Review follow-up to the #5516 carry. The 32 MiB decoded-body cap applied to every
gzip/deflate response, so a long, normally compressed SSE stream through the
SOCKS5 tunnel was cut once its cumulative output crossed the cap. Buffered
responses keep the absolute cap; event streams may continue while decoded bytes
stay within the greater of 32 MiB or 128x the coded bytes consumed, which still
stops high-ratio bombs.

* fix(codex): keep scanning PATH past a missing Windows candidate

Review follow-up to the #5515 carry. The held-handle reader reported a missing
file or directory as open-refused, so the default existence probe stopped the
PATH scan at the first absent PATHEXT candidate (for example codex.com) before it
reached an installed codex.cmd. NtCreateFile's object-name-not-found and
object-path-not-found statuses now map to a distinct not-found result that lets
the scan continue; every other failure still refuses.

* fix(server): require Windows ACL hardening before a frame-log append

Review follow-up to the #5515 carry. On Windows the frame log ignored a failed
permission change and appended anyway. Each append now hardens the target with
the required Windows ACL helper and checks that the path still names the opened
file before writing; any failure writes nothing.

* fix(devin): bind catalog authority to the tenant destination

Review follow-up to the #5517 carry.

- The observe-only OAuth snapshot applied the Copilot-validated apiBaseUrl to
  every provider, so a crafted Devin credential could carry a Copilot host that
  the snapshot claimed as its own. The overlay now applies only to github-copilot.
- Devin's live roster, stale fallback and cooldown were keyed by the token alone
  while discovery also depends on the validated tenant URL. The catalog authority
  and the matching routing-cache resolver now fingerprint the token together with
  the validated destination URL.

* fix(codebuddy): fail closed on unverified bridge turns and staging collisions

Review follow-up to the #5582 carry.

- With the capture-only tool bridge armed, a successful terminal event is no
  longer accepted unless the CLI's system/init frame confirmed the bridge server;
  a turn that ends without it fails with tool_bridge_init_missing.
- A tool_use block that arrives only in the complete assistant message, without
  the partial tool events the bridge captures, now fails the turn instead of
  being dropped silently; partial captures are deduplicated by id.
- The catalog and MCP config staging files are created exclusively (wx, 0600),
  like the prompt file, so a pre-existing file fails before spawn.
- The history-argument repair for a missing JSON object prefix is documented and
  tested as a provider-agnostic contract; other malformed strings keep {}.

* fix(service): keep service-command ownership bound to the recorded home

Review follow-up to the #5512 carry. On WSL with CODEX_HOME unset, the carried
allowance treated a legacy Linux ~/.codex install record as owned when discovery
now selects the Windows profile, so service stop could stop the Linux-home
service and then restore native Codex in the Windows home, and repair could
rewrite the recorded home. Service commands again require the exact recorded
home and name it in the refusal; the unattended startup inspector reaches the
same foreign verdict.

* fix(server): veto a package-tree restart when its server stops or loses ownership

Review follow-up to the #5513 carry.

- A package-tree restart accepted by the guard stayed scheduled after an explicit
  server.stop(), so the drain-and-respawn could reopen a server the caller had
  stopped. The caller that accepted a pending restart now receives a veto, and
  the guard uses it on dispose.
- When running as a supervised service child, the automatic path checks service
  home ownership when accepting and again before the handoff; a mismatch keeps
  the 503 fence and skips the restart.

* fix(security): resolve gh from fixed paths and look up pairing grants by digest

Review follow-ups to the #5516 carry.

- On Windows the automatically polled star-status route derived gh.exe roots from
  ProgramFiles and LOCALAPPDATA, so a process environment could select any
  absolute directory. Windows candidates are now the fixed system install paths,
  and the child PATH is only the resolved executable's directory. Other installs
  report gh as unavailable, which only hides the sidebar star state.
- Pairing redemption looked each guess up by scanning every live grant; the map
  is keyed by the grant digest, so the lookup is now a direct get. A valid grant
  still redeems behind a throttled source.

* test(server): cover the one-shot Aside sync capability end to end

Review follow-up to the #5516 carry, which added a one-shot, HMAC-bound
capability for the default ocx sync path without exercising it. A real listener
now proves single use, refusal on replay, wrong path, query, method, pid or port,
expiry and a bad MAC, and that the CLI default path performs the attestation and
a bodyless POST (through a narrow transport seam).

* test: register the review follow-up test files in the layout maps

Adds the three new test files from the L4 review follow-ups to both
scripts/test-layout/layout.json and tests/fixtures/test-layout-expected.json.

* test(grok): pin re-injection and strip for a nested user model table

Review follow-up to the #5281 reimplementation: two injections are byte
identical, every intermediate file parses, and strip restores the exact user
content.

* fix(server): harden a Windows frame log once per file identity

Re-review follow-up: requiring Windows ACL hardening on every append spawned
icacls for every relayed frame and could stall the realtime relay. The hardened
file identity (device and inode) is now remembered for the log path; an
unchanged file skips the respawn, and a replaced file at the same path is
hardened again before any write.

* fix(server): stop an automatic restart from handing off after an explicit shutdown

Security review follow-up to the #5513 carry. Once an automatic package-tree
restart entered its drain, an operator shutdown (signal or management stop)
could still be followed by the restart handoff, because the drain cannot tell
its own listener stop from an independent one. Explicit shutdown paths now mark
the process, and an admission-bound restart checks that mark before every
handoff step. Manually requested restarts keep their behavior.

* fix(server): mark a management stop before its asynchronous teardown

Security re-review follow-up: the management stop route marked the explicit
shutdown only after awaiting the shared teardown, so an automatic restart
draining concurrently could reach its handoff in that window. The mark now
precedes the first await after the stop is accepted.

* test(server): allow post-lookup pruning in the pairing digest regression

The digest-lookup regression trapped every iteration of the grant map, so a
valid redemption failed once session minting pruned expired grants after the
lookup (hosted CI test 4/4). The trap now fails only on a scan that precedes the
digest lookup, which is the regression it guards.

* fix: repair standalone bridge and restart ownership

Use the compiled CLI as the capture-only MCP entrypoint, release automatic restart fences on veto, align Devin discovery, and tighten Windows and local transport handling. Apply the documented Qoder prompt environment for both regions and update focused regressions and operator docs.
