Closes #23425.

New-thread shortcut hints remain visible on Usage, but their handlers unmount with the chat route. Move chat.new, chat.newLocal, and chat.newWithoutProject into AppSidebarLayout so they remain available on Usage, Settings, and project pages. Keep preview and chat-selection shortcuts in the chat route, preserve existing project selection and environment routing, and respect keybinding capture, terminal focus, and the command palette.

This is a focused fix for an obvious bug in existing advertised commands; it adds no new capability or product default. Web and desktop share the affected layout. Mobile has separate shortcut handling; providers, server contracts, and connection modes are unchanged.

Verification:

  • Added browser regression tests using real draft creation and router navigation with a project fixture. All four initial cases failed before the fix because navigation stayed on Usage, Settings, or the project page. The completed suite has nine passing cases, including macOS/Linux bindings and focus guards.
  • vp test run apps/web/src/components/AppSidebarLayout.browser.test.tsx apps/web/src/components/UsageToggleShortcut.browser.test.tsx: 11 tests passed.
  • vp run check:changed upstream/main: format, lint, knip, affected-package typechecks, and all nine regression tests passed.
  • Built-in T3 browser against isolated, seeded worktree state on Linux: before, Ctrl+Shift+N / Ctrl+Shift+O left Usage unchanged; after, Ctrl+Shift+N opens a draft and Ctrl+Shift+O opens the project picker with multiple projects. Native macOS desktop and remote/relay connections were not exercised; macOS key resolution is covered by the browser tests.

Approvability

Verdict: Approved at fe47b96

Macroscope's review found this PR approvable — This focused fix relocates existing new-thread shortcut handling into the global authenticated app shell so the advertised shortcuts work on Usage, Settings, and project pages while preserving chat-specific shortcut behavior. Regression tests cover routing, platform bindings, and focus guards, with no product-default or infrastructure changes.

📝 Walkthrough

New-thread shortcut handling now runs from AppSidebarLayout instead of the chat route. The handler resolves thread context and scratch-thread environments. Browser tests cover draft navigation from several routes and cases where shortcuts do not act.

Changes: New-thread shortcut handling

Layer / File(s) Summary
Move shortcut handling to the sidebar layout
apps/web/src/components/AppSidebarLayout.tsx, apps/web/src/routes/_chat.tsx, apps/web/src/components/AppSidebarLayout.browser.test.tsx
AppSidebarLayout handles new-thread shortcuts using the current context or a scratch environment. The chat route removes its handlers for these commands. Browser tests check draft navigation from usage, settings, and project routes, plus states where the shortcut is ignored.

Explanation

The description explains the problem, implementation, scope, linked issue, verification results, limitations, and UI evidence. It covers the required template information even though it does not repeat the template headings.

Full details: Linked Issues check

Explanation

Issue [#23425] requires the chat.new, chat.newLocal, and chat.newWithoutProject shortcuts to work where the sidebar shows their hints. NewThreadShortcuts now runs in AppSidebarLayout, which covers Usage, Settings, and project routes. The handler keeps project and environment selection, command-palette behavior, keybinding-capture checks, terminal and preview focus checks, and model-picker checks. _chat.tsx retains preview and chat-selection shortcuts. Browser tests cover Usage, Settings, project routes, macOS/Linux bindings, real draft creation, and focus guards.

Full details: Out of Scope Changes check

Explanation

The reviewed changes directly implement [#23425]. They move the three new-thread handlers to the shared sidebar layout and add focused browser regression tests. Preview and chat-selection handling remains in _chat.tsx. No unrelated changes to mobile handling, providers, server contracts, or connection modes appear in the reviewed changes.

Preserve the selected project scope on project pages.

/projects/$projectKey redirects to /settings/projects?project=$projectKey, where the settings scope represents the selected project group and optional environment. NewThreadShortcuts ignores that scope. With no active thread or draft, chat.newLocal uses the global defaultProjectRef, and chat.newWithoutProject uses the primary environment. For a selected project outside that default context, the shortcuts can target the wrong project or environment.

Resolve the settings scope to the appropriate project member and environment before invoking these actions. Handle grouped projects explicitly because one project key can represent multiple environment members.
