fix(web): keep saved default model when changing effort - #22193
Conversation
Changing effort in Settings wrote the fallback from resolveDefaultProviderModelSelection, so a turned-off or unavailable provider was replaced by another model. The row now keeps the saved model, notes that its provider cannot run, and hides effort until that provider is back.
ApprovabilityVerdict: Needs Human Approval Macroscope's review found this PR requires human approval — This change alters the product-default model settings UI and the persisted default selection when effort changes, including behavior for unavailable providers. Product-default changes require human review under the configured approval criteria. You can add or adjust custom eligibility rules. Learn more. |

When no active entry or model option exists,
ProviderModelPickerdisplaysprops.model. The existing missing-entry test supplies a fallback option, so it does not cover this branch. Add a case withoptions: [],includeEntry: false, and a saved model, then assert that the saved model label is rendered. This is a useful regression test, not a current production defect.🤖 Prompt for AI Agents

Reproduced the original issue on Linux in the real web app at ed9b7ca9: saved Claude Opus 5.5 → disabled Claude → changed the displayed Codex effort to High → re-enabled Claude. Persisted default remained Codex GPT-6-Astra High. Main recording. At PR head 8952d199, the 10 focused logic tests pass locally. I also merged that head with current main locally, without publishing or changing the contributor branch. The ordinary disabled-provider flow preserves Opus and hides effort; re-enabling restores the same model. Integration recording. One remaining display mismatch is reproducible on that integration: save Opus 5.5, hide it using its model-picker visibility switch, then disable Claude and return to General. Settings still stores Environment: Chrome 154 on Linux, 1280×800 CSS pixels, DPR 2, light theme, default browser font scaling, no device emulation. These are targeted interaction recordings, not the complete before/after proof set. Remaining proof matrix: unavailable/missing provider, project scope, multiple environments, narrow width and dark theme remain unverified. Both independent reviews returned FIX_FIRST. The cross-provider effort helper is also redundant under the component’s effort-lock guard; the original callback can remain after removing that helper and its three unreachable-state tests. No sensitive-surface changes found. CI currently has 27 successful checks. GitCafe checkout cannot resolve this cross-fork PR’s source repository ( |

The settings row kept the saved model, but the picker still labeled it with the first visible option. A locked or turned-off provider now keeps that model on the trigger. Effort changes use the original callback again. Co-authored-by: maco <macodev00@users.noreply.github.com>

Fail when image comparison fails.
If compare cannot read a screenshot, || true treats the error as an expected difference. The script can then report success without a valid diff image. Accept only the expected “images differ” exit status, and stop if compare or montage fails. ImageMagick distinguishes comparison errors from differing images by exit status. (legacy.imagemagick.org)

Create $out before redirecting output into it.
The shell opens "$out/$row-before.out" before node starts. run-row.mjs creates outDir only after it starts (mkdirSync at its Line 33). If $out does not exist, such as on the first run with the default /tmp/ev-22193, the redirect fails. The node command does not run. The script then reports a nonzero exit for both builds on every row, and nothing is recorded.
Add mkdir -p "$out" before the loop.

Guard malformed PID files before sending signals.
Number("") is 0, so an empty PID file can make process.kill(-pgid, "SIGTERM") target the caller’s process group. This is a narrow race: run-row.mjs and stills.mjs stop the server before starting it, but an interrupted startServer write can leave an empty file for a later stop, and stop.mjs can race with startup. Validate that pgid is a positive safe integer before either signal. Write the PID file through a temporary file and rename it atomically.

EvidenceSave a Claude default with High effort in Settings → Threads. Disable Claude in Providers, return to Threads, and change effort if offered. Re-enable Claude and inspect the saved default. Finally, disable Claude again and intentionally select Replay; navigate away and back to verify persistence. Chromium on Linux, 1280×800, light theme, fresh isolated data on both commits. Model identifiers are cosmetically redacted. Recordings omit startup/pairing and play at half speed.
The base saves the substituted Codex model when effort changes. The head retains Claude, hides effort while disabled, and restores editing when enabled. Intentional model changes save on both. AI-assisted; verified with the tests and tools listed above. Not shown:

Summary
Changing the default model's effort in Settings could replace the saved model. The Model row displayed
resolveDefaultProviderModelSelection, which substitutes another ready provider when the saved one is turned off, unavailable, or missing. The effort control then wrote that substitute, including at All environments scope.The row now keeps the saved model, notes that its provider is turned off, unavailable, or not on this environment, and hides effort until that provider can run. Choosing a different model on purpose still works.

claudeAgent / claude-opus-5-5and the row says Claude is turned off. The trigger showed Claude Sonnet 5.5 before and Claude Opus 5.5 after.retainedModelWhileProviderLockedasserts that the trigger label is Opus 5.5 when the provider is turned off or unavailable, and that it stays unset when the provider can run, so the first visible option remains the fallback. The redundant effort helper and its three tests were removed per review.Limitations: General settings, light theme, default viewport, with the saved provider turned off and Opus hidden. Project scope, multiple environments, a missing provider, narrow width, and dark theme were not captured.
