Summary

  • Follow up merged PR fix(service): launch the systemd unit through the stable ocx executable #2909 from current dev without reverting its stable-launcher direction.
  • Require Linux systemd launcher discovery to select a regular executable ocx file, continue past invalid earlier PATH entries, and keep the lexical shim path instead of resolving its versioned target.
  • Preserve only a provenance-authenticated OPENCODEX_BUN_PATH in launcher mode. Package-local bundled Bun paths remain rediscovered after upgrades, and the API token remains file-backed.
  • Make buildUnit() deterministic by requiring callers to pass launcher mode explicitly, replace the path-sensitive sh -c regression with argument-array execution, and cover quoted shim targets containing spaces and apostrophes.
  • Record the runtime boundary in the architecture and lifecycle documentation.

Verification

  • bun test tests/service.test.ts --timeout 30000 — 146 pass, 0 fail.
  • bun run test:changed --timeout 30000 — 9,421 pass, 8 skip, 0 fail across 522 selected files.
  • bun run typecheck — passed.
  • cd docs-site && bun run build — 401 pages built.
  • bun run test under a temporary HOME and a two-CPU affinity — 15,963 pass, 16 skip, 1 five-second timeout in tests/cursor-images.test.ts; the unrelated image suite passed 37/37 under the same CPU affinity with --timeout 30000.
  • Exact origin/dev reproduced the Log Guard failures only when CODEX_SQLITE_HOME was globally overridden; with the required temporary HOME, OPENCODEX_HOME, and CODEX_HOME and no conflicting SQLite override, its focused suite passed 18/18.
  • git diff --check — passed.
  • The five protected local runtime configuration files retained their pre-test SHA-256 values.

No live systemd unit, OpenCodex daemon, release branch, or user runtime configuration was changed.

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 Change Stack

📝 Walkthrough

Walkthrough

Changes

The systemd service now discovers the first regular executable ocx on PATH during installation. Unit construction receives runtime data explicitly and preserves only proof-bound Bun overrides. Tests cover executable validation, runtime provenance, and shim retargeting across upgrades.

Systemd launcher behavior

Layer / File(s) Summary
Executable launcher discovery
src/service.ts:10-19, src/service.ts:88-107, tests/service.test.ts:101-134
stableLauncherEntry now checks for regular executable files and uses the platform PATH delimiter. Tests cover candidate ordering, invalid entries, and filesystem permissions.
Runtime-aware unit construction
src/service.ts:59-65, src/service.ts:2602-2609, src/service.ts:2621-2626, tests/service.test.ts:854-855, tests/service.test.ts:924-936
cliEntry and buildUnit accept explicit runtime data. Launcher-backed units preserve override Bun paths, while stable-launcher units omit versioned Bun paths.
Upgrade-safe shim and documentation
tests/service.test.ts:3-9, tests/service.test.ts:953-976, structure/04_transports-and-sidecars.md:20-41, docs-site/src/content/docs/reference/cli/lifecycle.md:234-241
Tests invoke shims directly and cover apostrophes in versioned paths. Documentation describes launcher resolution, Bun provenance, token loading, and repair behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to ad6ac

The PR hardens Linux service launcher discovery and runtime provenance. It is mergeable with explicit follow-up to clarify the absolute PATH requirement, update localized lifecycle documentation, and improve recovery for partial installations that could temporarily leave the running unit and recorded launcher state inconsistent.

**mise** and **asdf** install into a versioned directory and delete the old one on upgrade, which
used to leave the unit pointing at files that no longer existed — systemd then restart-looped while
still reporting the service as installed. A shim path survives the upgrade, so the unit keeps
resolving. Source checkouts without an `ocx` launcher keep the previous direct Bun + CLI form.

trusted `OPENCODEX_BUN_PATH` selected before Bun starts is preserved through the shim; package-local
bundled Bun paths are deliberately rediscovered after upgrades instead of being pinned in the unit.

이 PR은 이미 들어간 #2909 를 더 단단히 한다. 지금 dev HEAD cfb70c972src/service.ts 89-98행 stableLauncherEntry 는 PATH 를 콜론으로만 나누고 existsSync 만 본다. 이름이 ocx 인 디렉터리나 실행 권한이 없는 파일도 고른다. 첫 항목이 그런 쓰레기면 뒤에 있는 진짜 실행 파일은 보이지 않는다. buildUnit 2597행은 launcher 를 안 넘기면 그 함수를 다시 부른다. 테스트와 진단이 호스트 PATH 에 묶인다. installSystemd 2675-2676행은 이미 한 번 찾아서 같은 값을 유닛과 상태에 넘긴다.

#2909 가 고친 것은 버전 관리자가 지우는 패키지 트리에 bun+cli 를 굽던 재시작 루프다 (#2898). 심을 어휘 경로 그대로 남기는 방향은 맞다. 심링크를 풀면 버전 디렉터리가 다시 유닛에 들어간다. 이 PR은 그 방향을 뒤집지 않는다. 고르는 조건을 일반 파일이고 실행 가능한 것으로 좁히고, 앞의 잘못된 항목은 건너뛴다. 경로 구분자는 path.delimiter 라서 테스트가 윈도에서 돌아가도 나눈다. systemd 자체는 리눅스다.

buildUnit 은 이제 호출자가 launcher 를 넘기게 한다. 기본값은 null 이라 직접 bun+cli 다. installSystemd 는 이미 넘기므로 설치 경로는 안 깨진다. 테스트가 buildUnit() 만 부르던 자리(96, 190, 215, 228행 근처)는 이제 호스트에 ocx 가 있어도 런처 모드로 몰래 바뀌지 않는다. 그게 이 변경의 목적이다.

런처 모드에서 패키지 안의 Bun 경로를 안 굽는 것은 #2909 와 같다. 이 PR은 durableBunRuntime().source === "override" 일 때만 OPENCODEX_BUN_PATH 를 남긴다. 운영자가 부팅 전에 고른 Bun 은 심을 거쳐도 유지된다. 패키지 로컬 bundled 경로는 업그레이드 뒤에 다시 찾는다. 토큰은 파일에서 읽는 기존 셸 서문 그대로다. #2107 불변과 맞다.

테스트는 디렉터리, 권한 644, 권한 755 세 PATH 항목을 실제로 만든다. 공백과 아포스트로피가 있는 설치 경로는 execFileSync 로 심을 실행한다. 예전 sh -c 문자열은 그 따옴표에서 깨진다. 본문은 tests/service.test.ts 146 pass 와 test:changed 9421 pass 를 적었다. types.ts/config.ts 분할과 무관하다. close-don't-rebase 대상이 아니다. 이미 설치된 옛 유닛은 여전히 스스로 못 고친다. ocx service repair 가 필요하다는 #2909 안내와 같다.

라인 service.ts 89-98 existsSync - 디렉터리나 비실행 파일을 고를 수 있다. isFile + X_OK 로 건너뛰는 쪽이 맞다. 심링크 파일은 stat 가 따라가므로 어휘 경로 후보는 그대로다.
라인 buildUnit 2597 - 기본이 재탐색이면 테스트가 CI 의 ocx 를 집어 초록이 될 수 있다. null 기본이 더 정직하다. 설치 함수는 이미 launcher 를 넘긴다.
경로 OPENCODEX_BUN_PATH 보존 - override 출처만 남긴다. 운영자가 그 값을 버전 디렉터리로 직접 가리키면 다시 핀이 된다. 그건 운영자 선택이다. bundled 경로를 굽는 것보다는 낫다.
경로 tests/service.test.ts 런처+override - 유닛에 process.execPath 와 OPENCODEX_BUN_PATH= 가 들어가야 한다. 테스트 bun 이 패키지 트리 안에 있으면 그 경로가 유닛에 보인다. 출처가 override 라서 의도된 동작이다.

메인테이너의 판단이 필요한 지점

  • 기본 launcher null 이 설치 이외의 진단 경로를 직접 bun+cli 로 고정해도 되는지 (installSystemd 는 이미 명시적으로 넘김)
  • override Bun 경로가 버전 트리여도 운영자 책임으로 둘지
  • #2909 이전에 깔린 유닛을 이 착지와 함께 한 번 더 repair 안내할지

너의 추천
머지하세요. #2909 방향을 유지한 채 고르는 조건과 유닛 빌더의 PATH 의존만 줄인다. 설치 경로는 이미 launcher 를 넘긴다. 기존 유닛은 이번에도 repair 가 필요하다는 점을 본문에 이미 있다.

Three CodeRabbit findings, all correct:

- The new test names cited `#2916`, a PR number guessed before this branch had
  one. The PR is #2958.
- `010` still described the effective-declaration reader as unimportable and
  left the export-versus-move decision open. B resolved it by moving all four
  helpers into `gui/tests/helpers/css-declarations.ts` and rewriting the
  original test to import them, so the doc now records that outcome and lists
  the module in the diff scope.
- `020`'s rendered CDP check asked whether each `button.switch` carries visible
  text or a `title`, which contradicts the wrapper rule its own item 3 states: a
  `showLabel` switch puts its text in a sibling inside `.switch-labeled` and
  carries no `title`. As written the check would have failed exactly the
  controls that phase fixes, so it now applies the wrapper-aware condition.

…n wrap (#2958)

* fix(gui): give the provider toggle a real flex basis so the header can wrap

The Models provider header collapsed between roughly 1040 and 1380px: the
provider name measured 0.0px and painted its glyphs across the active count,
and the alias chip broke into a six-line blob. Both were one cause. The
toggle's inline `flex: 1` resolves to `flex: 1 1 0%`, and a flex item with a
zero base size never reports a content requirement, so the header's existing
`flex-wrap: wrap` never learned the toggle needed room and handed it the 31px
the actions cluster left over. At 1100 the actions took 422.9 of 488px.

Two properties are needed and they pull against each other. Visibility comes
from `flex: 1 1 auto`, so the content enters the header's wrap decision.
Boundedness comes from removing every child's automatic min-content floor,
because a flex child stops shrinking at its own `min-width: auto` and the sum
of those floors can still exceed the card.

The child rule is quantified rather than enumerated. Four earlier drafts
bounded the row by naming the children that could overflow it - name, then
alias chip, then the count and badge - and each revision found another one.
The `svg` exemption is the inverse failure: the universal rule also matched
the chevron, whose inline `width: 14` is not a flex floor, and it rendered
2.5px wide while the containment check still reported success. Text children
abbreviate; icons have nothing to truncate.

Measured in a real browser at dpr 2: 20/20 cells clean across ko/ru/fr/en/de
x 1440/1280/1100/1024, red on the pre-fix stylesheet (ko/1100 three bad rows,
ko/1280 four). Containment holds at -2 on five stress cases including every
child forced to 64 characters, with the chevron at 14px. Screenshots and the
pixel readback that confirms the collapse are in the devlog unit.

Also lifts the effective-declaration CSS readers out of
viewport-scroll-caps.test.ts, where they were file-local, into
gui/tests/helpers/css-declarations.ts so this test can use them without a
third copy.
