Fixes SOU-2281

Related duplicate: SOU-2303

Summary

  • Add DEFAULT_HOME_VIEW_PAGE, defaulting to search for backwards compatibility.
  • Allow the public deployment to set DEFAULT_HOME_VIEW_PAGE=ask to make Ask the default home page.
  • Preserve explicit search and ask cookie preferences.
  • Keep the server home page, sidebar ordering, and client useHomeView fallback aligned.
  • Document DEFAULT_HOME_VIEW_PAGE in the environment variable reference.

DEFAULT_HOME_VIEW_PAGE is validated server-side and defaults to search when unset. Server Components read the configured value directly, while the client receives it through the existing useHomeView prop. EXPERIMENT_ASK_GH_ENABLED is no longer used to select the default home page, though it remains available for its other existing Ask GH behavior. No org/admin default-home setting, Prisma column, or Settings → Security deployment-default UI is added.

E2E verification

Existing dual-state UI evidence covers the authenticated new-user and anonymous flows, sidebar ordering, and cookie overrides. The current configuration rename was additionally smoke-tested on Sourcebot Cloud environment 3748cd60-8e0f-41dd-b260-77d11353d533:

  • DEFAULT_HOME_VIEW_PAGE unset → / rendered the Code Search landing page.
  • DEFAULT_HOME_VIEW_PAGE=ask/ rendered the Ask landing page.
  • The Ask landing UI may show the expected local warning that no language model is configured; routing does not require a model request.

Summary by cubic

Fixes SOU-2281 by making the default home page configurable per deployment. When no saved preference exists, the app now defaults to search or ask based on DEFAULT_HOME_VIEW_PAGE, which defaults to search for backwards compatibility.

  • Explicit search and ask cookie preferences continue to take precedence.
  • The server page, sidebar, client hook, and General settings view use the same configured default.
  • EXPERIMENT_ASK_GH_ENABLED no longer selects the default home page.
  • The environment variable is validated, documented, and covered by tests.

Written for commit 063dc65. Summary will update on new commits.

Review in cubic

Summary by CodeRabbit

  • New Features
    • Administrators can configure the default home page as Code Search or Ask. This setting applies when no saved preference exists; saved preferences take precedence. Code Search remains the default when no alternative is configured. General settings use the configured default.

Walkthrough

The changes add DEFAULT_HOME_VIEW_PAGE, which accepts "search" or "ask" and defaults to "search". The home page, sidebar, and general settings use this value when the home-view cookie is absent.

Changes

Configurable Home View

Layer / File(s) Summary
Define the default home view
packages/shared/src/env.server.ts, packages/shared/src/env.server.test.ts, CHANGELOG.md, docs/docs/configuration/environment-variables.mdx
The environment schema accepts "search" or "ask" and defaults to "search". Tests cover the default and configured "ask" value. The changelog and environment variable documentation describe the setting.
Resolve the home-view cookie
packages/web/src/hooks/useHomeView.ts
The hook accepts a default view and uses it when the document or cookie is absent. For a present cookie, it returns the extracted value as HomeView.
Use the configured default in app and settings
packages/web/src/app/(app)/page.tsx, packages/web/src/app/(app)/@sidebar/components/defaultSidebar/index.tsx, packages/web/src/app/(app)/settings/general/page.tsx, packages/web/src/app/(app)/settings/general/generalPage.tsx
The home page and sidebar use the configured default when the cookie is absent. General settings pass the configured default to the hook.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Merge Risk: 🔵 Low · up to 6cd7e

The configured Ask home page works consistently on the inspected no-cookie path. The remaining issue is changelog placement, which does not affect routing and can be corrected before merge.

P2: The raw cookie value is cast to HomeView without validation, then used for both landing routing and sidebar ordering. An invalid cookie value (user tampering or a stale/malformed value) makes the sidebar list Ask before Code Search while / still renders the Code Search landing, since page.tsx only treats exactly "ask" as Ask. Validate the cookie against the enum before using it: only accept "search" or "ask", otherwise fall back to env.DEFAULT_HOME_VIEW_PAGE.
