What Changed

Proposes a settings-completion contract: forms that announce success or close after saving first await confirmation from the store that owns the value. Delayed, failed, interrupted and stale completions have explicit observable outcomes.

Why

Awaiting a convenience updater that returns void cannot confirm persistence. The proposal distinguishes acknowledged saves from quiet optimistic preferences, preserves input after failure, and prevents an old receipt from closing a reopened form or a different environment's editor.

The implementation is #12874, which carries this documentation commit until this PR merges, focused on provider-add and custom-model forms. This PR contains only the proposed contract and does not claim every settings path is proven.

Validation

Document reviewed for scope and authoritative-persistence boundary. Public HIG Feedback and Loading references inform the rationale. Formatting and diff checks passed.

Checklist

• This PR is small and focused
• I explained what changed and why

Implemented by GPT-6 Astra (medium reasoning) in Codex; coordinated and reviewed by GPT-6 Astra in Codex.

Implementation: #12874.

Summary by CodeRabbit

• Documentation
  • Clarified when a saved preference can be treated as confirmed: the write must complete successfully, and failures must remain observable.
  • Documented when preference controls may update before saving finishes and how they should respond to a failed write.

📝 Walkthrough

Walkthrough

The documentation clarifies when a promise confirms a successful settings write. It also specifies failure handling requirements for optimistic preference controls.

Changes

Settings completion contract

Layer / File(s)	Summary
Completion confirmation rules docs/internals/consistency-settings-completion.md	A promise confirms persistence only if it resolves after a successful write and rejects on failure. Optimistic preference controls must observe failures, show an error, and reconcile displayed state; otherwise, they must await persistence.

In `@docs/internals/consistency-settings-completion.md`:
- Line 16: Update the completion definition in the consistency settings
documentation to use persistence semantics rather than excluding Promise<void>
return types: accept a promise only when it resolves after persistence completes
and rejects on persistence failure, while excluding persistClientSettingsPatch
because it catches failures and resolves.
- Around line 25-26: Update the consistency-settings contract to remove the
quiet optimistic exception unless persistClientSettingsPatch surfaces
client-write failures and reconciles the snapshot after persistence errors;
ensure persistScopedSettingsPatch observes and propagates the result so the UI
reports failures consistently.

Note

This comment is posted by Julius' dot

This adds an explicitly proposed contract for acknowledged settings-save behavior, rather than recording an agreed decision. CONTRIBUTING and the proposal rules place external product proposals in Ideas discussions. Please move the proposal there, obtain maintainer agreement on direction and scope, and link that decision when requesting reconsideration of the documentation.
