Summary

macOS desktop app failed at startup: "the bundled CLI could not resolve the runtime (exit no exit code)".

Root cause: Bun linker signature on the compiled ocx sidecar does not survive macOS page validation. The kernel kills it on launch (EXC_BAD_ACCESS, SIGKILL "Code Signature Invalid", namespace CODESIGNING, proven via DiagnosticReports .ips), so ocx resolve never runs and the desktop stays in resolving.

Fix: ad-hoc sign (codesign -s - -f) the sidecar in desktop/scripts/prepare-sidecar.ts on darwin, right after it is copied into src-tauri/binaries. Other platforms are untouched (guarded by process.platform).

Verification

  • Reproduced: bundled ocx --version printed nothing and exited nonzero; crash report shows EXC_BAD_ACCESS / SIGKILL (Code Signature Invalid).
  • After fix: ocx --version prints the version; ocx resolve --json attaches to the live runtime (pid, port, version).
  • Re-ran bun run prepare-sidecar: the new sign step executes and the prepared binary launches.
  • bun run typecheck clean.
  • bun run test (full suite): green except 9 timeout flakes in 3 files (responses-compaction-routing, service/process-state, native-profile-drain-server). Those 3 files pass 141/141 in isolation on this branch and on pristine upstream/dev; this change touches only an unimported build script (whose own test passes), so the flakes are unrelated.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed. (Not needed: build-script internals, no user-facing behavior change.)
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults. (Ad-hoc signing is local-dev only; the release signing flow is untouched.)

Summary by CodeRabbit

  • Bug Fixes
    • Improved macOS compatibility by applying ad-hoc signing to the standalone sidecar binary.
    • Prevented macOS page validation from terminating the sidecar unexpectedly.
    • Signing failures now correctly report an unsuccessful result.
    • This provides more reliable sidecar startup and execution on supported macOS environments.

이 PR은 macOS 데스크톱 앱이 켜질 때 묶여 있는 ocx CLI가 바로 죽어 버리는 문제를 고칩니다. Bun으로 만든 바이너리의 서명 정보가 macOS 검사에 걸려서 커널이 프로세스를 죽이고, 그래서 ocx resolve가 돌지 않아 앱이 resolving에 멈춰 있었습니다. 고쳐 주는 방법은 desktop/scripts/prepare-sidecar.ts에서 바이너리를 src-tauri/binaries로 복사한 직후, macOS(darwin)일 때만 codesign -s - -f로 임시(ad-hoc) 서명을 다시 씌우는 것입니다. 바뀐 줄은 6줄뿐이고 다른 OS 경로는 그대로입니다. base도 dev라서 방향은 맞습니다.

라인 - prepare-sidecar.ts의 if (process.platform === "darwin"): 지금 조건은 “이 스크립트를 돌리는 컴퓨터가 Mac인가”만 봅니다. “만들고 있는 타깃이 apple-darwin인가”는 보지 않습니다. 그래서 Mac에서 Linux/Windows용 sidecar를 만들면 codesign이 엉뚱한 파일에 붙을 수 있고, 반대로 Linux CI에서 darwin 바이너리만 만들면 서명이 아예 안 됩니다. 타깃이 *-apple-darwin일 때만(그리고 가능하면 host도 darwin일 때만) 돌리게 가드하는 편이 더 안전합니다.
라인 - tests/gui/gui-desktop-sidecar-script.test.ts: 이 테스트는 스크립트 문자열에 특정 단어가 있는지만 봅니다. 이번 PR이 넣는 codesign/darwin 가드는 검사하지 않아서, 나중에 서명 줄이 빠져도 테스트는 초록불을 유지합니다. 최소한 “darwin이면 codesign -s - -f가 있다” 정도의 문자열 검사를 추가하는 게 좋습니다.
라인 - sign.exitCode !== 0 후 process.exit(sign.exitCode): 기존 build:standalone 실패 처리와 같은 패턴이라 일관되긴 합니다. 다만 exitCode가 null이면 process.exit 인자로 애매해질 수 있으니, 실패 메시지를 남기고 고정 코드(예: 1)로 나가는 쪽이 읽기 쉽습니다.

메인테이너의 판단이 필요한 지점

릴리스 워크플로는 macOS에서 prepare-sidecar를 돌린 뒤, 나중에 Developer ID / Tauri 서명으로 다시 서명합니다. 여기 ad-hoc 서명이 “중간 단계”로만 남고 최종 패키지에서 덮어써지는지, 아니면 릴리스 검증(verify-macos-runtime.sh의 hardened runtime·entitlement 검사)과 충돌할 여지가 있는지 한 번만 확인해 주세요. PR 본문은 “릴리스 서명 흐름은 안 건드렸다”고 하지만, prepare 단계에 서명이 새로 들어갔으니 그 순서가 맞는지가 핵심입니다. 또한 이 PR은 아직 draft이고 리뷰 readiness 체크리스트가 비어 있습니다.

너의 추천

로컬 macOS 데스크톱 기동 버그 자체는 원인·수정·재현 설명이 분명해서, 가드만 타깃 기준으로 조금 다듬고 테스트에 codesign 존재를 한 줄 넣은 뒤 merge 후보로 보는 걸 추천합니다. types.ts/config.ts 분할이나 미리보기 배포 이야기는 이 변경과 무관하니 여기서는 닫아도 됩니다. draft 체크리스트를 채운 뒤 ready로 올려 주세요.

* fix(desktop): ad-hoc sign the bun sidecar on macOS after prepare

Bun's linker-signed standalone output is killed by macOS page validation
(CODESIGNING "Invalid Page"), so the bundled ocx sidecar never ran and the
desktop app stayed in "resolving". prepare-sidecar now reseals the copied
sidecar with an ad-hoc signature, but only when a macOS host prepares a
bun-darwin-* target, through the absolute /usr/bin/codesign; a failed or
unlaunchable codesign stops preparation. The decision and the spawn
boundary live in desktop/scripts/sidecar-signing.ts so they are tested
without running codesign.

Carries #5559.

* fix(cli): warn about state loss before and after codex-restart

ocx system codex-restart fully quits and relaunches the Codex desktop app,
which can discard unsaved composer drafts, model-picker selections, and
pending approval prompts. The missing --yes error, the confirmed human
output, the capability metadata, the generated skill surface, and the
runtime structure doc now name that concrete loss. The restart request,
the --yes gate, and the JSON payload are unchanged.

Carries #5488. Refs #4761 (the warning slice only; restart scope is
unchanged).

* feat(server): OCX_PROBE_TIMEOUT_MS raises the liveness probe ceilings

On hosts where a content filter or EDR network extension adds a fixed cost
to every loopback connect, the shipped 750 ms probe expires before a
healthy proxy answers and every CLI liveness consumer reports it down.
OCX_PROBE_TIMEOUT_MS (whole milliseconds, 1 to 30000) raises the ceilings
on such hosts.

The override only raises: the 750 ms shared default and the 1500 ms
stop/start ownership budgets keep their floors, so a small value can never
shorten the budgets that prevent a duplicate proxy. Values above 30 s are
ignored so the single-shot stop deadline stays bounded (at most about 90 s).
The wiring tests read the constants in child processes, so no other test
file can observe an override. The CLI reference in all eight locales and
structure/ops/service-and-sidecars.md describe the setting.

Carries #5409 with the floor and ceiling fixed during the carry.

* perf(desktop): keep a hidden login launch on the startup surface

A login launch that starts hidden behind a usable tray no longer loads the
full dashboard after Ready. It keeps the small bundled startup page, and the
tray's Open Dashboard, a second ordinary launch, and the shell's open command
all go through startup::open_dashboard, which performs the run's single
navigation before showing the window. Manual launches and visible no-tray
launches keep eager navigation.

Two gaps in the original change are closed here. An open that arrives during
startup is recorded before progress is read, and finish reads it after
recording Ready, so whichever side runs second navigates. A WebView that
refuses the navigation script gives the one-shot claim back, so the next
open retries. Both reset with each run. Rust tests cover the first,
repeated, refused, and in-flight opens; the desktop guide in all eight
locales, structure/desktop-shell.md, and ADR-5494 describe the behavior.

Carries #5498. Refs #5493 (hidden-autostart deferral).

* fix(update): respect mise-owned installations

An opencodex package installed by mise was updated by npm self-update
inside mise's tree, behind mise's back. Install detection now recognises a
mise install from the adjacent .mise.backend.toml (tool alias plus the
canonical npm:@bitkyc08/opencodex backend) on both the lexical and the
resolved package path, reports installer "mise", and refuses mutation
with "mise upgrade <alias>" before any proxy stop, package write, or
worker creation: in the Node launcher, ocx update, the dashboard update
check and worker, and the sidebar badge. Unreadable or contradictory
metadata on either path fails closed without inventing a tool name. The
dashboard hides the command chip when there is no verified command, and
the lifecycle reference in all eight locales and all ten GUI catalogs
describe the behaviour.

Changes made while carrying it onto current dev:
- ported onto the update ownership transaction and the package-tree
  restart guard that landed after the PR's base;
- two verified owners whose tool roots differ only by a symlinked
  ancestor (macOS /var -> /private/var) are compared by canonical
  directory, so a real install behind a symlinked data directory is not
  reported as contradictory;
- the launcher refusal test now runs on Windows too (junction plus
  npm.cmd), proves the fake npm never runs, and covers contradictory
  metadata;
- the structure note moved to structure/ops/service-and-sidecars.md to
  keep structure/runtime.md within its line budget.

* test(desktop): add the Linux packaged-shell E2E driver

desktop/scripts/linux-packaged-e2e.ts boots the real AppImage and deb
payloads under a private Xvfb, Openbox and D-Bus session with fresh HOME,
XDG, CODEX_HOME and OPENCODEX_HOME roots and a reserved loopback port,
then requires a visible OpenCodex window, the bundled sidecar's matching
/healthz identity, port and version, and a clean drain after the only
window closes. Its report records readiness time and process-tree RSS as
evidence, not as budgets. Release asset collection accepts an explicit
isolated bundle root, and the AppImage patchelf wrapper follows the active
CARGO_TARGET_DIR so each Linux format can build in its own Cargo target.

Changes made while carrying it:
- the window is closed through the window manager (wmctrl -i -c, the
  EWMH close request a close button sends) instead of xdotool windowclose,
  which destroys the X window and can end the app without Tauri's
  close/drain path; the app must then exit on its own with code 0 and no
  signal, which is asserted and recorded in the report;
- verify-linux-sidecar.sh takes the staged AppImage directory as an
  optional argument, keeping the local default path;
- workflow wiring and the tests that read workflow files are in the
  following commit.

* ci(desktop): run the Linux packaged-shell E2E and isolate Linux release formats

CI: a new desktop scope (desktop/, gui/, src/, the standalone build
scripts, package.json, bun.lock and ci.yml itself) selects desktop-shell
alongside the native scope. When selected, the job builds the dashboard
and the bundled sidecar, builds the AppImage and the deb in separate Cargo
targets with updater artifacts disabled, stages them read-only, and runs
the packaged-shell E2E under dbus-run-session, xvfb-run and Openbox. The
report is uploaded with a SHA-pinned upload-artifact. The workflow keeps
contents: read, uses no secrets, and installs no package into the runner.
The aggregate gate derives the widened desktop-shell expectation the same
way the job does.

Release: on Linux, each format is built in its own CARGO_TARGET_DIR, staged
read-only, and collected from that staged root; the existing job-scoped
signing inputs are unchanged.

Changes made while carrying it:
- current dev's scope step no longer handles a privacy output; only the
  desktop output was added to it and to the aggregate;
- the Linux sidecar verifier moved after the isolated AppImage build and
  staging, and verifies the staged AppImage directory; before, it would
  have run before any Linux bundle existed in the default target;
- wmctrl is installed for the window-manager close request;
- the scope and aggregate tests that landed on dev after the PR's base
  now model the desktop output, and a new test file carries the CI wiring
  assertions.

Carries #5502 (workflow part). Refs #5493.
