Follow-up to #6020, from the review on that PR. Retry records carry the credential generation, so a replaced or reauthenticated credential no longer waits out its predecessor backoff, and a failure that raced a replacement is not recorded. A local native-main admission refusal retries after one minute without doubling the upstream backoff. main account unavailable stays in the growing backoff; generation keying already lets a later token start clean.
Fixes #5494. A 429 saying "Your token-plan 1-week quota has been exhausted" took the 60-second default cooldown, so the combo offered the dead target again every minute; with one transient failure on the other target, every request in between got 503 No available targets. The phrase now counts as account-window exhaustion, which holds the target for the existing ten-minute cap. The match is anchored to the token-plan wording so per-minute quota messages keep the short cooldown.
Carried from #6050 into merge train round 3. Clearing the selection now succeeds while main is paused, so the dev test that pinned the old 409 is removed; codex-account-clear-paused.test.ts covers the new contract, including that an explicit paused-main selection still gets 409.

When the global config.toml is oversized, special, or unreadable and no project bypass is found, this new globalUnreadable branch is still rendered beneath the fixed heading “Project Codex config bypasses OpenCodex.” That tells the operator a bypass definitely exists while the following message correctly says routing is undetermined; render unreadable-global warnings under a neutral/separate heading instead.

In a root-run POSIX container where tmpdir() is the standard mode-1777 /tmp, the fixture's executable can never pass isTrustedSystemdRunFile: the production check deliberately examines every ancestor and rejects /tmp as world-writable. Consequently the new “accepts a root-owned executable” test fails consistently in that environment (reproduced here), adding an unexpected full-suite failure; create the positive fixture beneath a root-owned, non-writable ancestor instead.

Compare file identity with bigint stats
The identity checks on Line 37 and Line 56 compare numeric Stats.dev and Stats.ino values. NTFS and some other filesystems can return 64-bit inode values above Number.MAX_SAFE_INTEGER. When that happens, two different files can round to the same JS number. The check on Line 37 and the check on Line 56 could then fail to detect a swap on Windows. That swap-detection guarantee is the main purpose of this reader.
The fix is local. Use { bigint: true } for all four stat calls and compare the bigint fields. Size and mtime checks still work with bigint stats: use size, mtimeNs, and ctimeNs, and convert size with Number() for the buffer allocation. This size is safe to convert because the code already bounds it to 1 MiB.

Use a neutral heading for an unreadable-only warning.
If the global config read fails and no project bypass is found, formatProjectCodexConfigWarningsForConsole still prints “Project Codex config bypasses OpenCodex:”. The warning says global routing is undetermined, so the heading reports a bypass that was not established. Select the heading after checking whether any group contains a project bypass. Add an assertion for the unreadable-only console output.

Treat an empty lsof result as a successful empty scan.
lsof exits with status 1 when no socket matches. The catch block records this normal no-match result as a scanner failure. On macOS, the later scanner fallbacks can also fail. An idle port can therefore return ok: false instead of a successful empty listener set.
src/update/job.ts treats ok: false differently from an empty successful PID list. This can trigger the inconclusive-scan fallback and misleadingly report that listener discovery failed.

Allow root-owned sticky ancestors for the NixOS launcher.
When /run/current-system/sw/bin/systemd-run resolves under /nix/store, the current ancestor check rejects the standard root-owned, sticky, group-writable store mode 1775. The resolver then returns undefined, so guiUpdateWorkerCommand uses the detached spawn and the worker remains in the service cgroup. KillMode=control-group can kill it during proxy shutdown.
A root-owned sticky directory protects its root-owned child entries from replacement. Preserve the root-ownership check and allow this case.
Suggested fix
- for (const start of [dirname(path), dirname(resolved)]) {
- for (let dir = start, previous = ""; dir !== previous; previous = dir, dir = dirname(dir)) {
- if (!rootOnlyWritable(dir, stat)) return false;
- }
- }
+ const STICKY = 0o1000;
+ for (const start of [dirname(path), dirname(resolved)]) {
+ for (let dir = start, previous = ""; dir !== previous; previous = dir, dir = dirname(dir)) {
+ if (rootOnlyWritable(dir, stat)) continue;
+ let st: { uid: number; mode: number };
+ try { st = stat(dir); } catch { return false; }
+ if (!(st.uid === 0 && (st.mode & STICKY) !== 0)) return false;
+ }
+ }Add a regression case where /nix/store has mode 0o41775 and the resolver accepts the candidate.

Create the positive fixture beneath a trusted ancestor.
When tmpdir() resolves to /tmp, the root-gated test at line 160 reaches /tmp during isTrustedSystemdRunFile's ancestor walk. Since /tmp is commonly mode 1777, rootOnlyWritable returns false, so the test expects true from a rejected fixture. Use a root-level temporary directory for this positive case; / and the mkdtempSync directory provide non-writable ancestors.

In @tests/update/update-worker-launch.test.ts at line 123, Update the positive
fixture used by the root-gated test for isTrustedSystemdRunFile so its temporary
directory is created directly beneath `/`, avoiding `/tmp` in the ancestor walk.
Keep the existing general-purpose fixture unchanged for tests that do not
require trusted ancestors.

리뷰 · 우선순위 52 / 80이 풀 리퀘스트는 설정 화면이 Codex의 원격 링크에 들어갈 때는 접속 키를 바로 보내지 않는다. 우리가 띄운 ssh가 업데이트 워커의 Codex 할당량 자동 갱신은 마감 시각이 이미 있으면 사용량 퍼센트만 갱신하려고 반복해서 묻지 않는다. 발견이나 활성화가 실패하면 대기는 5분에서 시작해 60분까지 늘어나고, 그 기록에는 그때의 자격 증명 세대가 붙는다. 다시 로그인한 계정은 이전 자격 증명의 대기를 물려받지 않는다. 로컬에서 main이 바쁘다고 거절한 경우는 업스트림에 요청을 보내지 않은 것이므로 1분 뒤에 다시 시도하고, 대기 길이는 그대로 둔다.
콤보가 429 본문에서 #6056은 #6020과 같은 일을 하므로 닫아 두는 것이 맞다. src/server/port-reclaim.ts parseListenEntriesFromSs — PID가 없는 LISTEN 줄은 삭제하고, 스캔은 성공으로 끝난다. lsof가 다른 사용자의 소켓을 뺀 채 성공하면 ss로 넘어가지도 않는다. src/client/link-join.ts waitForReady의 주석은 확인이 안 되면 키를 보내지 않는다고 되어 있다. 터널은 src/combos/failover.ts ACCOUNT_EXHAUSTION_TEXT — 이 문장에 붙는 시간은 10분 상한이다. 이슈 본문의 메인테이너의 판단이 필요한 지점 PID를 못 단 LISTEN 줄이 있으면 스캔을 실패로 볼지 정하면 된다. 지금 주석과 구현이 다르다. connect 도중 터널이 죽으면 Promise.race는 조인을 실패로 바꾸지만, 이미 출발한 요청은 취소되지 않는다. 플랜은 이 간격을 structure/remote-link.md에 남기기로 했다. #5494를 10분 쉬기로 끝낼지, 본문에 적힌 리셋 시각을 읽을지는 따로 정하면 된다. 10분은 60초보다 길다. 한 주 쿼터의 리셋 시각은 아니다. 설정 조회만 읽기 상한이 있다. inject와 sync의 currentExternalCodexModelProvider는 여전히 readFileSync다. FIFO로 바뀐 config.toml이면 조회는 실패로 끝나고, 파일을 고치는 경로는 그 읽기에서 멈출 수 있다. src/update/job.ts는 1999줄이다. 파일 크기 가드는 2000줄 이상이면 실패한다. 너의 추천 PID 없는 LISTEN 줄이 하나라도 있으면 그 스캔을 실패로 처리하고 머지하면 주석과 맞다. 리눅스에서는 이미 있는 inode 검사로 소유를 확인해도 된다. #5494는 10분 홀드를 이 PR에 두고, 리셋 시각과 DeepSeek 502는 이슈에 남은 일로 적으면 된다. #6056은 닫힌 상태를 유지하면 된다. 설정 읽기 상한, systemd-run 경로, 쿼터 세대 키, account clear는 위 설명과 테스트가 같다. 이 댓글은 grok-bot이 작성했습니다 |

Summary
Merge train round 3, batch 3: five carried PRs, a review fix for #6020, and a fix for #5494, which was found and confirmed through the issue tracker in this round. Batches 1 and 2 landed as #6059 and #6061.
global_config_unreadableinstead of claiming routing is off.systemd-runonly from trusted root-owned absolute paths, probed off the request path.ocx account clear. An account whose id isautowins over the reserved word, and clearing works while main is paused.Fixes in this batch, one commit each:
NativeMainBusyErrorrefusal, which sends nothing upstream, retries after one minute without growing the backoff. Three regression tests, which fail without the fix.503 No available targets. It now takes the ten-minute exhaustion hold. The match is anchored to the token-plan wording, so per-minute quota messages keep the short cooldown.Integration notes:
src/update/job.tskept both imports from dev and #6037, and it sits at 1999 lines. The test-layout registries were unioned. #6050 removes the dev test that pinned the old paused-main 409 on clear, and its new test file covers the new contract.#6056 is closed as superseded by #6020. On dev, the retained earliest deadline already starts an idle window once, and #6020 stops the polling.
