Pull request overview

This PR significantly expands the frontend unit test suite across the unified stats system, card data sources, modal navigation utilities, dashboard chunk/prefetch utilities, branding/constants helpers, and multiple MCP hooks—aiming to increase branch/edge-case coverage and reduce regressions as these utilities evolve.

Changes:

Added extensive new/expanded Vitest coverage for stats formatting/resolution, registries, chunk/prefetch helpers, and branding/constants utilities.
Added new hook tests for modal navigation, persistence, and mission suggestions.
Expanded MCP hook test coverage for progressive SSE updates, abort handling, demo-mode branches, and REST fallbacks.

 import { cn } from '../../lib/cn'
 import { LOCAL_AGENT_HTTP_URL, FETCH_DEFAULT_TIMEOUT_MS } from '../../lib/constants'
-import { NAVBAR_HEIGHT_PX, BANNER_HEIGHT_PX } from '../../lib/constants/ui'
+import { NAVBAR_HEIGHT_PX, BANNER_HEIGHT_PX, DEV_BAR_HEIGHT_PX } from '../../lib/constants/ui'


DEV_BAR_HEIGHT_PX is imported but never used in this file. This will likely fail lint (unused import) and adds noise—either use it where appropriate or remove it from the import list.

Suggested change

import { NAVBAR_HEIGHT_PX, BANNER_HEIGHT_PX, DEV_BAR_HEIGHT_PX } from '../../lib/constants/ui'

import { NAVBAR_HEIGHT_PX, BANNER_HEIGHT_PX } from '../../lib/constants/ui'

+
+    // Clean up subscriptions
+    subscribeRegistryChange(listenerA)
+    subscribeRegistryChange(listenerB)
+  })


The listener cleanup is incorrect: calling subscribeRegistryChange(listenerA/B) again does not unsubscribe (it re-adds to the Set). This leaves listeners registered and can cause later tests to receive unexpected notifications. Capture the unsubscribe functions returned from subscribeRegistryChange(...) and call them here instead.

beforeEach is imported from vitest but never used in this test file. If eslint/no-unused-vars is enabled for tests, this will fail lint; remove the unused import or add the intended setup hook.

+
+    expect(mockLoader).toHaveBeenCalledTimes(1)
+
+    // Restore
+    DASHBOARD_CHUNKS['dashboard'] = originalLoader
+    vi.unstubAllGlobals()


In this test, vi.spyOn(DASHBOARD_CHUNKS, 'dashboard') is called before capturing originalLoader, so originalLoader becomes the spy wrapper rather than the real loader. Restoring with that value leaves the spy in place for subsequent tests. Capture the original loader before spying, and either restore the spy (mockRestore) or avoid spyOn entirely and just temporarily replace the property.

+    await waitFor(() => expect(result.current || true).toBeTruthy())
+
+    const fetchCountBefore = (globalThis.fetch as ReturnType<typeof vi.fn>).mock.calls.length
+


This test destructures only { rerender } from renderHook but then references result.current, which is undefined here and will throw at runtime. Destructure result as well (or remove the waitFor that references it) so the test actually runs.

+      // In demo mode, drifts come from demo data, fetch should not increase
+      // But the re-fetch effect should have fired
+      expect(true).toBe(true)
+    })


This test currently doesn't assert any observable behavior about the demo-mode transition (it ends with expect(true).toBe(true)). That means it can pass even if the re-fetch effect never runs. Add a real assertion (e.g., on fetch call count / localStorage writes / returned drifts) to validate the intended branch.

+import { describe, it, expect, beforeEach } from 'vitest'


beforeEach is imported but never used in this file. If lint checks test files, this will fail; remove the unused import (or add the missing setup/teardown it was intended for).

+    const EXPECTED_DASHBOARD_COUNT = 32
+    expect(Object.keys(DASHBOARD_CHUNKS)).toHaveLength(EXPECTED_DASHBOARD_COUNT)
+  })


The fixed EXPECTED_DASHBOARD_COUNT (=32) assertion is brittle and will fail any time a new dashboard chunk is added/removed (even if the change is correct). Since this file already asserts required keys explicitly, consider removing the total-count check or deriving the expected count from the expected+extended key lists to avoid unnecessary churn.
