Summary

Batch 4 of the bug-PR merge train: two open bugs that had no PR, implemented here.

  • [Bug]: Anthropic adaptive thinking is requested with default display (omitted), so long Opus max-effort thinking reaches Chat clients as minutes of heartbeat-only silence #5824, Anthropic adaptive thinking was silent. Opus 4.7+ defaults thinking.display to "omitted", so the stream carried signature-only thinking blocks and a Chat client saw minutes of : opencodex heartbeat with no reasoning delta; semantic-progress watchdogs (OMO's 300 s stream-start timeout) then cancelled the turn. The adapter now sends thinking: { type: "adaptive", display: "summarized" }. A request that hides the reasoning summary (reasoning.summary: "none", i.e. hideThinkingSummary) keeps the old shape and the provider default. Only the families on the adaptive wire are affected (Opus 4.7+, Sonnet 5, Fable); budget-thinking models are unchanged.
  • [Bug][Linux]: dashboard updater is killed when stopping its own systemd service #5750, the Linux dashboard updater killed itself. A worker spawned by the systemd user service stayed in the service cgroup, and the unit's default KillMode=control-group killed it when the updater stopped opencodex-proxy.service, leaving the proxy offline on the old package. When the proxy was started by systemd (INVOCATION_ID set) and a no-op systemd-run --user --scope --quiet --collect -- true probe succeeds, the worker is now launched through that scope (the reporter's verified workaround). --scope registers systemd-run's own PID in the scope and then execs the worker (systemd v255 src/run/run.c start_transient_scope → execvpe), so update-job.json still records the worker's PID. Off Linux, outside systemd, or without a usable user bus, the plain detached spawn is unchanged. The helper lives in the new src/update/worker-launch.ts because src/update/job.ts is a few lines under the 2000-line new-file threshold.

Docs: docs-site/.../reference/adapters.md notes the adaptive display behaviour; structure/ops/service-and-sidecars.md records the worker launch.

Left for maintainers (not in this PR): #5465 (whether combo force should respect a pinned caller effort is a product call, and it overlaps open #5631), #5501 (awaiting the redacted request the maintainer asked for), and the credential-path items #5880, #5877 and #5831, which need their own security review.

Verification

  • bun x tsc --noEmit: exit 0. bun run structure:check, bun run privacy:scan: pass.
  • tests/adapters/anthropic (32 files, adaptive shape updated in three assertions plus a hideThinkingSummary case that fails before the change), tests/update/update-worker-launch.test.ts (new: scope launch under systemd, plain spawn without systemd-run, outside systemd or off Linux), update-job, windows-deploy-close-regressions, layout, ratchet and structure guards: 684 pass, 0 fail.
  • tests/claude-integration + tests/chat + MiniMax reasoning split: 1058 pass; the one failure (claude-desktop-first-party apply returning 409 in the multi-file run) passes alone on this branch and on dev.
  • A Kimi review raised two blockers on the systemd launch (--collect with --scope, and the recorded PID); both were checked against systemd v255 src/run/run.c: CollectMode is applied to any transient unit, and the scope path execs the command in place.
  • Full suite left to hosted CI at this head.

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.

Closes #5824
Closes #5750

Summary by CodeRabbit

  • New Features
    • Adaptive-thinking models now display summarized thinking by default. When thinking summaries are hidden, the provider’s default display setting is retained.
  • Bug Fixes
    • On supported Linux systems, update workers launched from a user service now run outside the proxy service’s control group. Other platforms and systems without the required support retain the existing launch behavior.

Opus 4.7+ defaults thinking.display to "omitted", so the stream carries
signature-only thinking blocks and a Chat client sees minutes of heartbeats with no
reasoning delta during a long think; semantic-progress watchdogs then cancel the turn.
The adapter now sends display "summarized" for adaptive thinking unless the request
hides the reasoning summary, in which case the provider default stays.

Closes #5824
…vice cgroup

A worker spawned by the systemd user service stayed in that service's cgroup, and the
generated unit's default KillMode=control-group killed it when the updater stopped
opencodex-proxy.service, leaving the proxy offline on the old package. When the proxy
was started by systemd (INVOCATION_ID set) and a no-op `systemd-run --user --scope`
probe succeeds, the worker is launched through that scope; --scope moves systemd-run
into the scope and execs the worker, so the recorded PID stays the worker's. Every other
case keeps the plain detached spawn. The helper lives in src/update/worker-launch.ts
because job.ts sits just under the 2000-line new-file threshold.

Closes #5750

📝 Walkthrough

Walkthrough

Anthropic adaptive-thinking requests now set summarized display unless the caller hides the thinking summary. On non-Windows systems, the update worker launch path uses a systemd user scope when Linux, INVOCATION_ID, and the systemd-run availability check conditions are met.

Changes

Anthropic adaptive thinking

Layer / File(s) Summary
Adaptive-thinking display setting
src/adapters/anthropic.ts, tests/adapters/anthropic/anthropic-reasoning.test.ts, docs-site/src/content/docs/*/reference/adapters.md
The adapter requests display: "summarized" for adaptive thinking unless hideThinkingSummary is true. Tests cover both display behavior and omission of the field. Adapter documentation describes the behavior in the listed locales.

Linux update worker launch

Layer / File(s) Summary
Scoped launch command
src/update/worker-launch.ts, tests/update/update-worker-launch.test.ts
guiUpdateWorkerCommand returns a systemd-run scoped command when Linux, INVOCATION_ID, and the availability check conditions are met. Otherwise, it returns the original command and arguments. Tests cover these conditions and fallback cases.
Worker launch integration
src/update/job.ts, structure/ops/service-and-sidecars.md, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json
The non-Windows worker launch path spawns the command and arguments returned by guiUpdateWorkerCommand. The operations documentation describes the scoped launch condition. The test-layout files map the new test to the update domain.

이 풀리퀘스트의 바탕은 dev예요. src/types.ts와 src/config.ts를 나누는 글이 아니고, #5824나 #5750을 고치는 다른 열린 풀리퀘스트는 없어요.

고치는 버그는 두 개예요.

클로드가 오래 생각하면 채팅에는 몇 분 동안 하트비트만 보여요. Opus 4.7부터는 생각을 숨기는 쪽이 기본이라, 기다리는 프로그램이 멈춘 줄 알고 요청을 취소해요. 이제 그 계열(Opus 4.7+, Sonnet 5, Fable)에는 생각 요약을 내 달라고 해요. 요약을 숨기라고 한 요청은 예전 모양을 유지해요. 토큰 예산으로 생각하는 옛 모델은 그대로예요.

리눅스에서 대시보드 업데이트를 하면, 업데이트 일꾼이 프록시 서비스와 같은 묶음에 남아요. 서비스를 끄는 순간 일꾼도 죽어서, 프록시는 꺼지고 옛 패키지가 남아요. systemd가 프록시를 켠 경우에만 systemd-run --user --scope로 일꾼을 다른 묶음에서 실행해요. 그 명령이 없거나 리눅스가 아니면 예전처럼 그냥 띄워요.

라인 - src/update/worker-launch.ts probeSystemdRun — systemd-run이 되는지를 한 번만 기억해요. 첫 업데이트가 사용자 버스를 잠깐 못 만나면, 프록시를 다시 켜기 전까지 계속 예전 방식으로 띄워서 일꾼이 또 같이 죽어요.

라인 - src/update/job.ts spawnGuiUpdateWorker — 그 검사는 업데이트를 시작하는 요청 안에서 최대 5초를 기다려요. systemd-run이 실행된 뒤 바로 죽으면 요청은 실패로 끝나지 않아요. PID만 적고 작업은 running으로 남아요. 죽은 PID는 나중에 낡은 작업으로 정리돼요.

라인 - src/adapters/anthropic.ts — 요약을 붙이는 곳은 우리가 클로드 요청을 조립할 때예요. Messages를 원본 그대로 넘기는 설정은 이 글이 안 바꿔요. 이슈 #5824의 첫 실험은 이미 요약을 달라고 했는데도 생각 글이 없고 서명만 왔어요. 테스트는 보내는 JSON에 display: "summarized"가 있는지만 봐요.

메인테이너의 판단이 필요한 지점

요약을 기본으로 보내면, 숨기라고 하지 않은 요청은 생각 토큰이 늘고 요약 글이 클라이언트로 나가요. 그 변화를 받아도 되는지는 정해 주세요.

요청에 effort가 없고 공급자 기본 effort만 있으면 hideThinkingSummary가 켜져서 이번 수정이 빠져요. 그 경우도 요약을 보낼지는 정해 주세요.

너의 추천

두 이슈의 방향과 같아요. 같은 주제로 닫을 글은 없어요. 머지해도 돼요. systemd-run이 안 된 결과는 프록시가 켜져 있는 동안 붙잡아 두지 말고, 다음 업데이트에서 다시 확인하세요. #5824는 채팅으로 생각 글이 한 줄이라도 나가는지 한 번 확인해 주세요.

🟠 Major · Persist the scoped worker PID, not the systemd-run PID. · worker-launch.ts:12-15

src/update/worker-launch.ts:12-15
🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Persist the scoped worker PID, not the systemd-run PID.

When the Linux proxy runs under systemd, spawnGuiUpdateWorker starts systemd-run --scope. In scope mode, systemd-run remains the parent of the worker, so Node's ChildProcess.pid identifies systemd-run, not the worker in the transient scope.

startUpdateJob persists that wrapper PID. When the proxy service stops, systemd can kill the wrapper in the proxy service cgroup while the worker remains in the separate scope cgroup. Startup recovery then sees a dead persisted PID, marks the active job failed, and permits another update while the first worker is still running.

Keep the scoped launch, but resolve the actual worker PID before writing the job record. Use the wrapper only for launch-error handling and unref. A scope-specific PID lookup or an explicit worker PID handshake must provide the PID used by staleActiveUpdateJobReason.
