Review details

Systems and components

• observed — app (ui) was modified; 3 changed files map to changed impact.
• observed — gitbooks (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in app/src/components/settings/panels/tests/builtinCloudProviders.test.ts: The endpoint and auth-style parameterized test no longer includes the cheaperinference case. The separate test asserting empty endpoint and undefined auth style for unknown slugs was also removed.
• observed — Modified behavior in app/src/components/settings/panels/tests/builtinCloudProviders.test.ts: The expected built-in provider slug set no longer includes cheaperinference.
• observed — Modified behavior in app/src/components/settings/panels/ai/providerIcons.tsx: The import of the bundled cheaperinference.svg asset was removed.
• observed — Modified behavior in app/src/components/settings/panels/ai/providerIcons.tsx: The cheaperinference asset mapping was removed, so the slug no longer resolves to a bundled mark or appears in the asset-derived PROVIDER_ICON_SLUGS.

_{A rabbit checked the provider row,
And saw one entry go.
The icon left its place,
The docs now match the case.
The tests no longer show it so.}
