• apps/web/src/app/(onboarding)/setup/AdoSourceControlConfig.tsx:134 Point the "Entra Enterprise Apps" link at the Enterprise applications pane. It now targets the Enterprise applications blade, where users can copy the service principal object ID required by Azure DevOps.
• packages/types/src/setup-source-control-config.ts:311 Update the existing assertions for the renamed organization label. StepSourceControlConfig.client.test.tsx:387 and SourceControlConfigForm.client.test.tsx:271 now expect "ADO Organization (URL slug)", and both targeted web test files pass.
