리뷰 · 우선순위 47 / 80이 PR은 서브에이전트 폴백 체인을 대시보드에서 편집하게 하고, 암호화 V2 네이티브 전용 경로에서 추천 로스터( 구성은 세 층이다. (1) GUI: 보안 방향은 HEAD의 #3242 결정과 맞다. 네이티브 ChatGPT 자격 증명을 쓰는 모델을 조용히 폴백에 넣지 않고, 대시보드에서 명시로 켠 때만 로스터를 쓴다. 로스터가 비어 있으면 합성 폴백을 만들지 않는다. 테스트도 스위치 on/off/unset 경로를 점수가 낮은 이유다. 첫째, 기능 자체는 암호화 V2 복구 열차의 자연스러운 후속이다. 다만 ‘지금 바로 넣어야 하는 작은 구멍’보다는 ‘옵트인 GUI + 설정 키’에 가깝다. 중복 원본(#3253)은 이미 닫혔고 이 PR이 통합본이므로 닫지 말고 다듬는 쪽이 맞다.

Validation: typecheck, GUI build, focused GUI test (prior run), and diff check passed. The remaining local limitation is the known Windows Bun user-lock/atomic-write ENOENT race; CI checks currently pass. |

Polished the fallback-chain editor in a7f7ddb: compact icon-only reorder/remove actions, improved spacing for the interval/toggle/save controls, and responsive stacking for narrow dashboard widths. Refreshed screenshot: docs-site/public/pr-screenshots/subagent-fallback-settings-v2.png. |

Give the fallback remove control a model-specific accessible name.
On Line 119, the button exposes only × to assistive technology. It does not identify the fallback model that it removes.
Add aria-label={t("sub.removeAria", { m: modelName })}. Use the existing icon pattern for the visual control.
As per coding guidelines: “Preserve accessibility: keyboard operation, labels, focus behavior, semantic controls, and readable validation errors.”

Move the visible unit into the localization catalog.
On Line 127, ms is hardcoded visible UI text. Render the complete polling label through a translation key, including the unit.
As per coding guidelines: “No hardcoded visible UI text.”

Reject invalid polling intervals before sending the request.
saveFallback sends fallbackPollMs directly from gui/src/pages/Subagents.tsx:204-207. The Save button is type="button", so the input constraints at SubagentDelegationSection.tsx:127 do not run. The server accepts only integer values from 5,000 through 600,000 and returns 400 otherwise. Validate this range before saving and show a localized field error.

Persist confirmed fallback settings in the session cache.
On Lines 210-211, saveFallback updates React state only. It does not update writeSessionListCache.
After a successful save and remount, seedSubagents can restore the old fallback values. The cached snapshot bypasses the loading skeleton, so a user can immediately save the stale values and overwrite the configuration that was just persisted.
Write the confirmed models and pollMs values to the cache after a successful response. Ensure that the primary and fallback save paths cannot replace each other’s cache fields with stale closure values.

Summary
Expose the ordered sub-agent fallback chain and availability polling interval in the Subagents dashboard through the existing
/api/subagent-model-fallbackAPI. The fallback chain and featuredsubagentModelsroster remain separate settings.This source diff contains the editor and screenshot. It does not implement a roster-reuse switch or change runtime fallback routing. Those claims were removed from the earlier JSON-encoded description to match the actual commits.
Maintainer carry and follow-up corrections are in #3878, including preservation of unavailable configured models, committed-cache isolation, controlled GUI regressions, and issue #1533 compatibility guidance. This source PR is retained until that carry is landed by the release-train main session.
