Summary

  • add an opt-in defaultEffortMode: "fallback" | "force" combo setting without changing existing reasoningEffortMode semantics
  • let a combo configured with defaultEffortMode=force replace caller reasoning effort with its validated defaultEffort
  • preserve requested, effective, and wire effort separately in request/attempt telemetry
  • expose the setting through configuration types, management API/CLI, GUI data round-trip, and documentation

Safety and compatibility

  • default behavior remains fallback; configurations without the new field are unchanged
  • force requires a valid defaultEffort and fails closed before request mutation
  • unknown model capability and empty effort ladders do not inject or override effort
  • per-target resolution remains isolated and downstream effort caps still apply

Verification

  • targeted Responses tests: 7/7 passed
  • TypeScript typecheck: passed
  • privacy:scan: passed
  • docs build: 425 pages built
  • broader grouped suite: 220/221; the sole catalog-retirement DELETE failure was reproducible as unrelated/flaky while affected tests pass in isolation
  • test:changed was stopped after the GUI dependency installation remained stalled for more than 13 minutes

No runtime deployment, Hermes profile change, gateway restart, OAuth/config change, or live /opt/opencodex modification is included.

Summary by CodeRabbit

  • New Features

    • Added configurable combo effort modes: fallback preserves caller-selected effort, while force applies the configured default.
    • Added CLI and workspace support for configuring and persisting effort mode.
    • Effort settings now adapt to each target’s supported capability range.
  • Bug Fixes

    • Unknown or unsupported target capabilities now fail safely without applying an incompatible effort.

Review Change StackReview Change Stack

📝 Walkthrough

Walkthrough

The change adds defaultEffortMode to combo configuration. Fallback preserves caller effort. Force replaces valid caller effort when target capabilities support the configured default. CLI, GUI, management API, request handling, logging, documentation, and tests now support the policy.

Changes

Combo default effort policy

Layer / File(s) Summary
Policy contract and normalization
src/types/config.ts, src/types.ts, src/combos/types.ts, tests/codex-integration/combos.test.ts, docs-site/src/content/docs/guides/combos.md, docs-site/src/content/docs/reference/configuration/routing.md
Defines OcxComboDefaultEffortMode, validates fallback and force, requires defaultEffort for force mode, normalizes omitted values to fallback, and documents target capability resolution.
CLI, GUI, and management API wiring

Adds CLI parsing, GUI draft and PUT serialization, sparse API responses, force-mode preservation, and round-trip validation.
Child request effort resolution
src/combos/request.ts, src/server/responses/core.ts, tests/codex-integration/combos.test.ts, tests/server/server-combo-failover-e2e.test.ts
Applies fallback or force mode during child request construction, handles unknown or unsupported capabilities, and preserves the original caller effort in logs and attempts.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to afb9f

The new force policy is validated and applied across configuration and request handling, but CLI users cannot clear a forced default effort in one command without also specifying fallback mode. This is a bounded configuration usability issue that should be corrected before broad CLI use.

이 PR은 combo에 defaultEffortMode: "fallback" | "force" 를 추가합니다. 지금까지 defaultEffort 는 호출자가 effort를 안 넣었을 때만 채워 주는 기본값이었는데, force 를 켜면 운영자가 정해 둔 기본 effort가 유효한 호출자 effort도 덮어씁니다. 예: 클라이언트가 medium을 보냈어도 combo가 max로 강제할 수 있습니다. 기본값은 그대로 fallback이라, 필드를 안 넣은 기존 설정은 동작이 안 바뀝니다.

지금 dev HEAD는 9587750ce (#4051 wp2: quota/catalog/streaming/storage/history 버그픽스 묶음) 입니다. 패키지는 2.49.0이고, tip 방향은 출하 가능한 백로그 마감입니다. 이 PR은 그 tip의 버그픽스가 아니라 combo 제품 옵션입니다. Hermes처럼 클라이언트가 medium을 고집해도 운영 기본을 올리고 싶을 때 쓰라고 e2e 테스트 이름에도 나와 있습니다. 급히 넣지 않아도 되는 축이지만, 범위는 작고 옵트인이라 품질만 맞으면 다음 작은 product 배치에 넣기 좋습니다.

코드 경로는 현재 checkout과 맞습니다. 핵심은 src/combos/request.tsconcreteComboRequestBody 입니다. force이고 호출자 effort가 isCodexReasoningEffort 로 유효할 때만 덮어쓰고, banana 같은 잘못된 값·능력 미지(undefined)·빈 사다리는 손대지 않습니다. 덮어쓸 때도 기존 #3108 규칙처럼 resolveEffortAtOrBelow 로 타깃 사다리 안에서 깎습니다. 설정 검증은 src/combos/types.ts 에서 force인데 defaultEffort가 없으면 400으로 막고, src/types/config.ts / src/types.tsOcxComboDefaultEffortMode 를 추가합니다. 런타임 연결은 src/server/responses/core.tshandleComboResponses 한곳입니다(프로덕션에서 concreteComboRequestBody 호출이 여기). 관리 API 희소 직렬화(src/server/management/combo-routes.ts), CLI --effort-mode (src/cli/combo.ts, 기존 force 유지), GUI 데이터 왕복(gui/src/combo-workspace-data.ts), 문서(combos.md / routing.md)까지 같이 갑니다. 단위·관리 API·failover e2e·CLI·GUI 데이터 테스트가 새로 붙었습니다.

types.ts / config.ts 분리 캠페인 관점에서는 무효화 대상이 아닙니다. 이미 config 쪽에 있는 combo 타입에 필드를 하나 더하는 추가분이고, close-don't-rebase 대상이 아닙니다.

라인 - gui/src/components/combo-workspace-controls.tsx / combo-workspace-detail-panel.tsx / combo-workspace-add-modal.tsx - 데이터 레이어만 force를 왕복하고, Combos 워크스페이스 UI에는 force/fallback 선택 UI가 없습니다. 운영자가 GUI만 쓰면 force를 켤 수 없고, CLI/API로만 설정 가능합니다. PR 요약의 GUI 노출은 반쪽입니다.
라인 - gui/src/components/combo-workspace-detail-panel.tsx baselineSyncKey - 키에 defaultEffortMode 가 빠져 있습니다. API로 force가 들어간 combo를 GUI에서 다시 열면 baseline 동기화/리마운트가 force 차이를 놓칠 수 있습니다. draftEquals 는 고쳤지만 sync key는 안 고쳤습니다.
경로 - Enforce PR target / UI screenshot - GUI 파일을 건드렸는데 스크린샷이 없어 quality gate가 missing UI screenshot 으로 실패했고 mergeStateStatus는 BLOCKED입니다. force UI를 안 넣을 거면 GUI 터치 범위를 줄이거나 waiver/스크린샷이 필요합니다.
경로 - Cross-platform CI / React Doctor - 상태가 action_required입니다. 신규 기여자 첫 실행 승인 대기일 수 있어, 메인테이너가 워크플로 승인하기 전에는 초록불이 아닙니다.
경로 - 텔레메트리 주장 vs 패치 - PR 본문은 requested / effective / wire effort를 분리 보존한다고 적었지만, src/server/responses/core.ts 패치는 원래 호출자 effort를 requestedEffort 에 다시 찍는 수준입니다. force 이후 실제 wire effort를 별도 필드로 남기는지는 이 diff만으로는 분명하지 않습니다. 디버깅할 때 ‘요청 medium → 전송 max’를 한눈에 보려면 effective/wire 표기를 문서·로그 스키마와 맞춰 주세요.
경로 - 검증 - 작성자 기준으로 Responses 타깃 7/7·타입체크·privacy:scan·docs는 통과했고, test:changed 는 GUI 의존성 설치가 13분 넘게 멈춰 중단했습니다. GUI 데이터 테스트는 로컬에 추가됐지만 changed 스위트 전체 신호는 불완전합니다.
경로 - src/types/config.ts defaultEffort 주석 - 여전히 ‘클라이언트가 생략할 때만’처럼 읽힙니다. force가 생기면 주석도 ‘fallback일 때 생략 시에만 / force면 덮어씀’으로 고쳐야 문서와 타입이 같습니다.

메인테이너의 판단이 필요한 지점

  • force를 Combos GUI에서 공식 지원할지, 아니면 CLI/API 전용 고급 옵션으로 두고 GUI 파일 변경·스크린샷 게이트를 어떻게 처리할지.
  • 비용/지연이 커질 수 있는 force를 기본 문서·경고 수준으로 충분한지, 아니면 management UI에 더 강한 경고가 필요한지.
  • 지금 tip(wp2: land seven contributor bug fixes (quota, catalog, streaming, storage, history) #4051 버그픽스 마감) 직후 product 옵션을 바로 넣을지, 다음 작은 배치로 미룰지.
  • 신규 기여자 CI(action_required) 승인 시점.

너의 추천
방향은 좋습니다(옵트인·fail-closed·#3108 사다리 유지). 다만 지금 바로 merge하지 마세요. (1) GUI에 force 토글을 추가하거나, GUI 노출을 포기하고 GUI 변경/스크린샷 게이트를 정리하고, (2) baselineSyncKey 에 defaultEffortMode를 넣고, (3) Cross-platform CI 승인 후 초록을 확인한 다음, 2.49 tip 버그픽스와 섞지 말고 다음 small product 랜딩 후보로 두세요. types/config 분리 때문에 close할 이유는 없습니다.

⚠️ Unverified finding
Verification did not complete.

Do not copy arbitrary client input into effort telemetry.

Line 2685 accepts any string from reasoning.effort. Lines 2721-2724 and 2796-2799 then store it in RequestLogContext and the request attempt. A client can submit token-like text in this field, and child-request validation does not protect this logging path.

Store this value only when it is a recognized reasoning effort, or apply the request-log metadata sanitizer before assignment. Verify that every RequestLogContext serializer also redacts or rejects arbitrary requestedEffort values.

As per coding guidelines, “tokens and OAuth material must never be logged or serialized into responses.”

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Allow --effort - to clear an existing force mode.

When the existing combo has defaultEffortMode: "force" and the user runs ocx combo set <id> ... --effort - without --effort-mode, Line 106 restores "force" after Line 98 sets defaultEffort to null. The management API then rejects the update because force mode requires a valid default effort, so the user cannot clear the effort in one command.

Only preserve the existing force mode when effort !== "-", or set the mode to "fallback" when the user clears the effort. Add a regression test for this command path.

Proposed fix
-  if (effortMode === undefined && existing?.defaultEffortMode === "force") combo.defaultEffortMode = "force";
+  if (effortMode === undefined && effort !== "-" && existing?.defaultEffortMode === "force") {
+    combo.defaultEffortMode = "force";
+  }

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Reject force mode without a valid default effort.

defaultEffortMode: "force" can coexist with a missing or null defaultEffort. normalizeComboConfig then produces defaultEffort: null, and concreteComboRequestBody returns the unchanged child request. This silently preserves the caller effort instead of failing closed.

Validate this cross-field invariant during configuration normalization and reject the request at dispatch as a defense in depth. Add coverage for direct configuration with defaultEffortMode: "force" and no valid default effort.
