• preserve every runtime effort, including off, and block exact duplicates
• roll back optimistic retry settings after failed saves
• cover selection, duplicate, off, and failed-save behavior

Summary by CodeRabbit

• New Features
  • Choose a reasoning effort for each fallback model, or leave it unset to use the model’s default.
  • The effort selector is available when the selected model supports it. Changing models clears the selected effort, and fallback choices can use different effort settings.
  • Exact duplicate fallback selections are prevented.
• Bug Fixes
  • If saving fallback settings fails, the confirmed settings are restored instead of leaving unsaved changes displayed, and an error message is shown.

Walkthrough

The fallback editor now supports selecting a reasoning effort for each fallback model. It tracks confirmed settings and restores them in the interface when a save fails.

Changes: Fallback effort settings

Layer / File(s)	Summary
Effort-qualified fallback selection components/ModelsConfig-panels.tsx, components/ModelsConfig.test.mjs, CHANGELOG.md	The editor adds an optional effort to a fallback selector. The effort control is disabled when the selected model is unavailable, and exact duplicate selectors cannot be added. Tests cover high, off, and duplicate selection. The changelog describes the selector format and model-default behavior when effort is unset.
Confirmed settings and failed-save recovery components/ModelsConfig-panels.tsx, components/ModelsConfig.test.mjs	Successful loads and saves update the confirmed settings snapshot. If a save fails, the editor discards queued changes and restores the last confirmed settings, or an empty object if none exist. A test checks the failed-save behavior.

Security review details

Security Blast Radius

• observed — The changed editor writes retry settings into the existing native global configuration through the same endpoint. That endpoint also handles security-sensitive approval settings, but the PR does not add controls for those settings or change their server-side validation.

Trust Boundaries and Controls

• observed — The new UI obtains effort options from the selected runtime entry and uses the complete selector for duplicate prevention. These are editor controls, not authorization controls: the unchanged server accepts nonempty fallback strings independently of catalog membership or duplicate checks.

Resilience and Maintainability Implications

• inferred — A lost response can leave the editor showing an older acknowledged snapshot even after persistence succeeded, because configuration is written before the response and the failure path does not refetch. Ambiguous completion already existed before this PR; the change reverses the local display policy rather than establishing a server rollback guarantee.

filter against chain, so models remain available with different selectors. Rely
on the exact-selector check in the candidate-add flow to prevent duplicate
