Summary

The WidgetKit extension installed, registered with pluginkit, and was never offered in the
widget gallery. Signing looked like the cause and was not — the released build is signed and
notarized and the widget is missing there too.

The entry point was gone. app/Package.swift forced the executable's entry to
_NSExtensionMain and app/Sources/OpenCodexWidget/main.swift held only a comment, so nothing
referenced OpenCodexWidgetBundle and no code ever handed it to the extension host. Read off the
shipped bundle:

LC_MAIN entryoff -> _NSExtensionMain
nm: SnapshotProvider present, OpenCodexWidgetBundle absent
Info.plist: NSExtensionPointIdentifier = com.apple.widgetkit-extension
            NSExtensionPrincipalClass  = (absent)

pluginkit registers from the Info.plist, which is complete, so registration succeeded.
NSExtensionMain then looked for an NSExtensionPrincipalClass that a SwiftUI widget does not
declare, because Xcode's @main on the WidgetBundle is what connects it instead. Nothing
errored; the gallery simply had no configuration to offer. main.swift now calls
OpenCodexWidgetBundle.main() — the same entry @main expands to — and the linker override is
gone. SwiftPM cannot use @main here because @main and a main.swift in one target are
mutually exclusive.

The release never signed the extension. release.yml ran build-widget.sh with no env:
block while MACOS_SIGN_IDENTITY was set one step later on the Tauri build, which never reads it,
so the script took its codesign --force --sign - branch on every release. The bundler does not
re-sign anything under PlugIns/ — its nested-code walker knows .framework, .xpc and
.app, not .appex — so an ad-hoc extension with no team identifier shipped inside a Developer
ID host. This PR imports the certificate into a temporary keychain before the widget build and
deletes it in an always() step, passes the identity to the widget build, adds --options runtime alongside --timestamp, and asserts the result (strict verification, team identifier,
runtime flag, secure timestamp) instead of printing it.

Security review requested. This touches release automation and certificate handling, which
MAINTAINERS.md marks as requiring explicit security review. The certificate is decoded into
RUNNER_TEMP, imported into a per-run keychain with a random password, wiped, and the keychain
is removed in an always() step. No secret is echoed.

Stacked on #5329.

Verification

  • Widget rebuilt locally: LC_MAIN now resolves to the Swift _main and the bundle's symbols are
    present in the binary.
  • tests/clients/desktop-widget-entry.test.ts passes and was driven red by reinstating the linker
    override.
  • tests/test-layout.test.ts and tests/test-layout-tooling.test.ts pass with the new file
    registered.
  • The signing half needs maintainer-held credentials; the proof is a notarized artifact installed
    on a machine that did not build it, launched once, with the gallery then checked. NOT RUN here
    and recorded as outstanding in the devlog.
  • Full local suite: NOT RUN.

Checklist

  • Behavior change covered by a focused regression test
  • Docs updated where user-facing behavior changed (devlog decade doc)
  • No credential, request-body, or account-identifier logging introduced
  • Targets dev through its stack parent

Walkthrough

The change stabilizes the macOS WidgetKit extension, adds release-signing setup and verification, applies the Start at Login default once before tray installation, and adds source, workflow, layout, and documentation checks.

Changes

Desktop stabilization

Layer / File(s) Summary
Widget entry and packaging
app/Package.swift, app/Sources/OpenCodexWidget/*, app/Widget-Info.plist, .github/workflows/ci.yml, tests/clients/desktop-widget-entry.test.ts, structure/desktop-shell.md
Package.swift:6 raises the deployment target to macOS 14 and adds -application-extension at 17-42. The widget keeps @main and _NSExtensionMain, removes availability gates, adds bundle metadata, and checks the linked bundle symbol at .github/workflows/ci.yml:1218-1223.
Release signing and verification
.github/workflows/release.yml, desktop/scripts/build-widget.sh, tests/ci-workflows/ci-workflows.test.ts
release.yml:239-414 imports a temporary certificate keychain, passes signing variables to the widget build, verifies the extension and every bundled Mach-O, and cleans up the keychain. build-widget.sh:69-72 enables the hardened runtime for signed builds.
First-run Start at Login behavior
desktop/src-tauri/src/first_run.rs, desktop/src-tauri/src/lib.rs, tests/clients/desktop-start-at-login-default.test.ts, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json
first_run.rs:1-41 uses a persistent marker and enables autostart once. lib.rs:105-107 calls the function before tray installation. The new tests check guards, ordering, marker persistence, and test-layout registration.
Validation and landing support
devlog/_plan/260920_desktop_app_stabilization/050_landing.md
The landing plan documents stacked-branch merge checks, retained and deferred repairs, and the timing of macOS installation-document updates.

P1 Badge Move retention-days out of the cleanup script

In .github/workflows/release.yml, adding this run: | block places the existing retention-days: 7 line inside the shell script instead of under actions/upload-artifact. Consequently, every macOS package job that reaches cleanup finishes by trying to execute a command named retention-days:, exits with status 127, and blocks the dependent attach-release job. Move retention-days back into the upload step's with: mapping.

P1 Badge Register cleanup before creating certificate material

If certificate decoding, security import, or any later setup command fails, set -e exits before this line publishes the keychain path to GITHUB_ENV; the always() cleanup step then sees an unset variable and deletes neither the keychain nor the .p12 file, leaving release credentials on disk until runner teardown. Export cleanup paths before the first fallible operation and have the cleanup step remove both artifacts.

P1 Badge Do not echo the Apple team identifier

On every signed macOS release, .github/workflows/release.yml writes the complete codesign -dvvv description to the public Actions log; the immediately following assertion confirms that this output contains TeamIdentifier=$APPLE_TEAM_ID, so the workflow now logs an account identifier. Keep the description in memory for the assertions and emit only a generic diagnostic when verification fails.

Requesting changes after explicit release/workflow security review of exact head f29ea0055a10f0c06318abde92b0e82d2f1aff59.

The widget entry-point direction is sound, but the release path has three blockers:

  1. .github/workflows/release.yml: retention-days: 7 was displaced from actions/upload-artifact and is now indented inside the Remove the signing keychain shell block. On macOS the step attempts to execute a command named retention-days: and fails; the upload also loses its explicit retention. Move it back under the upload step’s with: block.
  2. The always() cleanup learns the keychain path only through GITHUB_ENV, which is written after decode, keychain creation, import, partition-list setup, and certificate deletion all succeed. Any failure before that leaves the .p12 and possibly the keychain in RUNNER_TEMP, while cleanup sees no path and does nothing. Cleanup must derive the fixed per-run paths independently and always remove both the certificate file and keychain, including partial-import failures; it should not depend on the success-path environment export.
  3. This step runs only on macOS, whose BSD base64 uses -D for decode; base64 --decode is the GNU spelling and is not portable to the hosted macOS runner. Use the macOS form (or a cross-platform decoder already available on the runner) and pin it with a focused workflow assertion.

Keep triggers, permissions, release-secret scope, and the release-only signing requirement unchanged. After these are fixed, run exact-head hosted release/workflow checks; the credential-backed notarized-artifact proof remains an explicit release gate. This PR also remains stacked on #5329, whose icon-generation blockers must land first before retarget/rebase to dev.

이 PR은 맥 데스크톱 위젯이 갤러리에 안 뜨던 이유를 고칩니다. 예전에는 링커가 _NSExtensionMain으로만 들어가고 OpenCodexWidgetBundle을 아무도 호출하지 않아서, 설치·등록은 되는데 갤러리에는 아무것도 안 나왔습니다. 지금은 main.swiftOpenCodexWidgetBundle.main()을 호출하고, 잘못된 링커 엔트리는 빼 둡니다. 또 릴리스에서 위젯 확장이 임시(ad-hoc) 서명만 타고 나갔던 문제도 같이 손봅니다. 인증서를 위젯 빌드 전에 키체인에 넣고, MACOS_SIGNING 정체성을 넘기고, hardened runtime·타임스탬프를 붙인 뒤 서명을 검사합니다. 같은 묶음으로, 메뉴바 앱이 재부팅 후 안 보이는 문제를 막으려고 첫 실행에 한 번만 Start at Login을 켭니다. 소스 순서 회귀 테스트와 위젯 엔트리 테스트도 들어 있습니다.

라인 - .github/workflows/release.yml · Remove the signing keychain 스텝의 run: 안에 retention-days: 7이 그대로 들어가 있습니다. 원래 Upload desktop releasewith:에 있어야 할 YAML인데, 셸 스크립트 마지막 줄로 밀려 갔습니다. macOS 패키지 잡이 cleanup까지 오면 retention-days:라는 명령을 실행하다 실패(exit 127)할 수 있고, attach-release도 막힐 수 있습니다. 업로드 스텝으로 다시 올려야 합니다.
라인 - .github/workflows/release.yml · 인증서 import가 GITHUB_ENV에 키체인 경로를 쓰기 전에 실패하면, always() cleanup은 변수가 비어 있어 키체인/.p12를 지우지 못할 수 있습니다. 실패해도 지울 경로를 먼저 정해 두고 cleanup이 둘 다 지우게 하는 편이 안전합니다.
라인 - .github/workflows/release.yml · 서명 검증 스텝이 codesign -dvvv 전체 출력을 Actions 로그에 echo합니다. 바로 아래에서 TeamIdentifier=$APPLE_TEAM_ID를 검사하므로, 공개 로그에 Apple 팀 ID가 남을 수 있습니다. 검사는 메모리에서 하고, 실패할 때만 짧은 진단만 남기는 편이 맞습니다.
라인 - desktop/src-tauri/src/first_run.rs · 마커가 없으면 기존 설치에도 Start at Login을 켭니다. 문서에는 “아직 릴리스 태그가 없어서 기존 사용자 없음”이라고 적혀 있지만, 스택이 머지된 뒤 이 PR이 늦게 들어가면 이미 깐 사용자에게도 한 번 켜질 수 있습니다. 의도인지 확인이 필요합니다.

메인테이너의 판단이 필요한 지점

베이스가 dev가 아니라 스택 부모 codex/260920-app-icons(#5329)입니다. dev로 합칠 때 스택 순서와 무효·중복 PR 정리가 필요합니다. 서명·인증서 처리는 보안 리뷰 대상이고, 작성자도 깨끗한 설치에서 갤러리 확인은 여기서 못 했다고 적어 두었습니다. Start at Login 기본값을 켜는 정책도 제품 판단입니다. 지금 CI 일부(gates / test shard)가 빨간 상태라, 실패 원인이 이 diff인지 스택/환경인지 같이 보면 좋습니다.

너의 추천

retention-days YAML 깨짐을 먼저 고친 뒤 다시 돌려 보세요. 그다음 키체인 cleanup을 “만들기 전에 경로 등록” 쪽으로 옮기고, codesign -dvvv 로그에서 팀 ID가 안 나가게 줄이세요. 위젯 엔트리·첫 실행 로그인 기본값 방향은 설득력 있습니다. 서명 쪽은 메인테이너 자격증명으로 릴리스 아티팩트를 한 번 받아, 다른 머신에 설치한 뒤 갤러리에 위젯이 보이는지까지 확인한 다음 머지하는 걸 추천합니다. preview deploy 이야기는 스킵합니다.

Re-checked replacement head d5d75b308049dd1782d091bbb237982ebe2003a4. The only change since my requested-changes review is app/Widget-Info.plist; none of the three release-workflow blockers were addressed. The misplaced retention-days, early-failure keychain/PKCS#12 cleanup gap, and macOS-incompatible base64 --decode remain release blockers. Current exact-head CI is also red, and the stacked parent #5329 remains blocked. Please keep this unmerged until those boundaries are fixed on a new head and replacement hosted CI is green.

Re-checked current head 31e6d44494c50cdfa9f84ce47d4e724b13223c34. The new commit changes only the widget entry-point/deployment-target implementation and its focused evidence; it does not modify .github/workflows/release.yml or close any requested release/security change. The existing requested-changes review therefore remains fully applicable, and the stacked parent #5329 is still blocked. The entry-point correction can be reconsidered after the release path is separated/fixed and the stack is rebased onto dev.

The WidgetKit extension installed, registered with pluginkit, and was never offered in the
gallery. Signing looked like the cause and was not: the released build is signed and notarized and
the widget is missing there too.

app/Package.swift forced the executable's entry to _NSExtensionMain and main.swift was a comment,
so nothing referenced OpenCodexWidgetBundle and no code handed it to the extension host. The
shipped binary shows it: LC_MAIN pointing at _NSExtensionMain, SnapshotProvider present and the
bundle absent. pluginkit registers from the Info.plist, which is complete, so registration
succeeded; NSExtensionMain then looked for an NSExtensionPrincipalClass that a SwiftUI widget does
not declare, because Xcode's @main on the WidgetBundle is what connects it instead. Nothing
errored and the gallery had nothing to offer. main.swift now calls OpenCodexWidgetBundle.main(),
which is what @main expands to, and the override is gone.

Separately, release.yml ran build-widget.sh with no env block while MACOS_SIGN_IDENTITY was set
one step later on the Tauri build, which never reads it, so the script took its ad-hoc branch on
every release. The bundler does not re-sign anything under PlugIns - its nested-code walker knows
.framework, .xpc and .app, not .appex - so an ad-hoc extension with no team identifier shipped
inside a Developer ID host. The certificate is now imported before the widget build and the
keychain deleted in an always() step, the widget build receives the identity, build-widget.sh adds
--options runtime alongside --timestamp, and a following step asserts strict verification, the
team identifier, the runtime flag and a timestamp instead of printing the signature.

tests/clients/desktop-widget-entry.test.ts holds the entry point and was driven red by
reinstating the linker override. The signing half needs maintainer credentials and a clean
install to prove; that is recorded as outstanding rather than claimed.
…ation runs

A menu bar app that is not running has no menu bar item, so leaving Start at Login off by default
meant an installed app was simply absent after the next reboot, with nothing on screen to explain
why. That is not a neutral default for an app whose main surface is the menu bar.

first_run::apply_start_at_login_default runs once per installation, keyed on a marker in the app
config directory. The marker is written before the login item is touched and is never removed, so
a user who turns the setting back off keeps it off: the next launch sees the marker and does
nothing. Writing afterwards instead would let a failed enable retry on every launch and eventually
flip the setting back on under someone who had deliberately turned it off. Every failure is
silent, because being unable to register a login item is not a reason to stop the app from
starting.

It runs before tray::install so the tray's Start at Login checkbox reads the state this leaves
behind. The behaviour is not macOS-gated: the autostart plugin implements Linux autostart entries
and the current-user Windows Run registration too.

tests/clients/desktop-start-at-login-default.test.ts reads the ordering out of the source, because
that ordering is the entire contract and is invisible from behaviour alone.
Every widget macOS ships declares CFBundleSupportedPlatforms and CFBundleDisplayName. Ours
declared neither, because Xcode writes both and a SwiftPM-assembled appex has no build system to
write them. An extension bundle that does not say which platform it supports gives the system no
reason to consider it on this one.

Checked against the widgets on a macOS 27 install: Shortcuts, Tips and Reminders all carry
CFBundleSupportedPlatforms = [MacOSX], and the two this bundle lacked are the only structural
Info.plist differences between them and this one.
…ntry

A widget extension needs @main on the WidgetBundle and the _NSExtensionMain linker entry, and
either one alone produces a widget that is never offered in the gallery.

Without @main nothing references the bundle, the linker drops it, and the extension still
registers with pluginkit because the Info.plist alone is enough - so the gallery has no
configuration to offer and nothing anywhere reports a problem. That is what shipped.

Without the entry override the Swift main runs instead of the extension host's bootstrap and
ExtensionFoundation traps in _EXRunningExtension._shared. Measured on a real install: EXC_BREAKPOINT
on every launch, one crash report per attempt, and chronod logging "query failed - will try lazy
reload later" while the gallery stayed empty. With both in place the crash reports stop and chronod
processes the extension normally.

The deployment target moves to macOS 14, which drops the now-redundant per-declaration availability
guards and puts the binary's minos at 14.0, matching the working widgets on the machine this was
measured on.

Also recorded: the app-sandbox entitlement is not optional. Removing it does not fail at launch -
pkd refuses to register the bundle at all, saying "plug-ins must be sandboxed", which is why the
host writes its snapshot into the extension's own container.
…identity

Signing the extension by name is not enough. A bundler signs what it placed and nothing else, and
the binaries that get missed in practice are the ones with no extension to filter on - so a check
that names paths will keep passing while an unsigned executable rides along inside the bundle and
notarization rejects the whole submission.

This walks the built app, identifies executables by their Mach-O magic bytes rather than by path
or suffix, and fails the job naming any file that does not carry the configured team identifier.
Without a configured team it says so and skips, so a fork still builds and still cannot pretend to
be signed.
…mean something

Review caught four defects in the previous revision of this workflow change, one of them mine and
serious.

retention-days had been displaced out of the desktop upload action and into the cleanup step's
shell body, where it is not a setting but a command that does not exist. Every macOS release job
would have failed with "retention-days:: command not found", and the artifact would have taken the
default retention on the way there. It is back in the action's with block.

The keychain path is now recorded before the keychain is created, so a failure part way through
still leaves the cleanup step something to delete, and the decoded certificate is removed by a
trap rather than by a line a failure can skip past.

The bundle-wide Mach-O sweep ran before Tauri produced a bundle, so it inspected nothing and
passed. It now runs after the assets are collected and fails when it finds no app bundle or no
Mach-O at all - a sweep that examined nothing is exactly the outcome it exists to prevent.

All three signing checks were fail-open: with the secrets absent they printed a note and exited
zero, while the unsigned artifact was still uploaded and attached. They now refuse a non-dry-run
release outright and keep the permissive path only for a local or dry run.

The step comment also claimed prior releases had shipped an ad-hoc extension inside a notarized
host. No release has published a macOS application, so the comment says what is true instead: a
defect that had not yet reached anyone.
…-part entry

structure/ ownership obliges the doc for an area to move with the source, and this branch changed
two things the desktop-shell note did not describe.

first_run.rs turns Start at Login on once per installation, with the marker written before the
login item so a user who turns it back off keeps it off. The widget needs @main on the bundle and
the _NSExtensionMain linker entry together, and the sandbox entitlement is mandatory because pkd
refuses to register an unsandboxed plug-in at all - which is the reason the shell writes its
snapshot into the extension's container rather than anywhere more obvious.
…he Mach-O sweep

Two holes left by the previous revision.

Only the certificate and the team id were guarded, so a real release missing APPLE_ID or
APPLE_PASSWORD still ran: the Tauri CLI skips notarization without failing when the notary
credentials are absent, and the unnotarized artifact is uploaded and attached exactly as a good
one would be. The five credentials are now checked together, and a non-dry-run release stops with
the missing names rather than shipping something that looks finished.

The bundle sweep recognised four of the eight Mach-O leading words, so a fat 64-bit or big-endian
binary was skipped in silence while the other files kept the inspected-something counter healthy.
All eight are listed now.

The public install guidance is left alone on purpose, and the landing note says why: those pages
describe an artifact that does not exist yet, and they should move with the first notarized
release rather than ahead of it.
The executable-name half of this landed separately as #5351, in a better form: it reads
CFBundleExecutable from the bundle rather than restating the name, so it follows the config
instead of drifting from it. What remains here is the assertion that has no equivalent.

A widget extension with no widget in it is indistinguishable from a working one by every other
check in this job: the appex builds, the signature verifies, pluginkit registers it, and the
gallery is simply empty. That is what shipped, and it shipped silently. Reading the WidgetBundle
symbol out of the binary is the only place in the build where its absence is visible.
Xcode sets APPLICATION_EXTENSION_API_ONLY on an app-extension target, and SwiftPM has no such
target, so the flag has to be passed by hand. The two projects that have a SwiftPM-built widget
extension working both do exactly this alongside the _NSExtensionMain linker entry, and the public
report of the ExtensionFoundation crash this branch hit traces it to precisely the setup SwiftPM
cannot express.

Verified on a real install after the change: the extension registers, chronod captures its
descriptors, and no crash report is produced. The devlog records what the same report settles -
ad-hoc signing does not block the gallery, App Groups do not work ad-hoc so writing into the
extension's own container is the documented fallback, and the host and extension CFBundleVersion
must match, which they do.
The guard splits the workflow on step names and scans from each "run: |" to the end of the block,
which for the last step of a job runs on into the next job's header. Adding a cleanup step at the
end of package-desktop made it read attach-release's job-level "if: inputs.dry-run != true" as
shell interpolation inside the step above it - a condition, not a script, and not reachable by
injection.

Each block is now cut at the first line that dedents to job level, which is where the step's
script actually ends. The guard still fails on a real interpolation: driven red by putting an
inputs expression inside a run block, and green again once removed.
… linker entry

-application-extension is load-bearing and nothing asserted it: the existing nm check proves the
WidgetBundle was linked, which stays true with the flag removed, and the runtime crash it prevents
leaves the build, the signature and the pluginkit registration all looking fine. It sits beside the
_NSExtensionMain assertion because the two are one contract - the projects that have a SwiftPM
widget extension working supply both.

structure/desktop-shell.md now records all three requirements together and says plainly that
nothing observable distinguishes a broken one from a working widget.

Driven red by deleting the flag.

Require APPLE_SIGNING_IDENTITY in the credential preflight.

The widget build reads this secret at Line 296, but the required-set loop does not check it. If the other five values exist and this value is absent, the certificate import succeeds, build-widget.sh falls back to ad-hoc signing, and the later TeamIdentifier assertion fails after unnecessary build work.

Add APPLE_SIGNING_IDENTITY to this step’s env: block and to the required credential list.

Proposed fix
           APPLE_PASSWORD: ${{ secrets.APPLE_PASSWORD }}
           APPLE_TEAM_ID: ${{ secrets.APPLE_TEAM_ID }}
+          APPLE_SIGNING_IDENTITY: ${{ secrets.APPLE_SIGNING_IDENTITY }}

Correct the recorded entry point.

Lines 58-63 and app/Package.swift state that the working extension uses _NSExtensionMain. This verification record instead reports _main and labels _NSExtensionMain as the previous value. That describes the failed intermediate configuration and makes the incident record internally inconsistent.

Update the capture to show the final _NSExtensionMain entry, or label it explicitly as output from the failed experiment.

dev is red on tests/ci-workflows/release-desktop-scripts.test.ts. The case
locating the certificate import keyed on the step name "Import the Apple
signing certificate for the widget", which is the name #5345 proposed. #5339
landed the same import first under the name "Import the release signing
certificate", and the conflict resolution that merged #5345 correctly kept
dev's workflow and dev's stricter import while carrying #5345's test text
forward. The subject of the assertion is still present and still correct; only
the label it searched for is gone, so indexOfStep returned -1.

Locate the import and the cleanup by the codesign keychain commands they run
instead of by their titles, which is what the case actually cares about and
what a rename cannot silently take away. The p12 assertion moves to the trap
dev's step installs, which is stronger than the plain deletion it replaces
because it also fires when a later command in the step fails.
