 # Phase 13 Plan 10: Frontend Health UX, Reconnect, and Shared Browser Mutation Surface Summary
 **One-liner:** Store-backed single-source health map (D-12), no-probe-on-navigation invariant (D-13), cached-metadata reconnect (D-14), Google Drive consent copy (D-17), and reactive rendered-flow test mock that confirms the health banner and Reconnect action surface through the shared StorageBrowser.
 ## Tasks Completed
 | Task | Name | Commit | Key Files |
 |------|------|--------|-----------|
 | 1 (GREEN) | Store-backed health, reconnect UX, no-probe, Google Drive consent | 60afb02 | cloudConnections.js, SettingsCloudTab.vue, StorageBrowser.vue, CloudFolderView.vue, cloudConnections.test.js |
 | 2 (GREEN) | Reactive rendered-flow test mock — health banner and no-probe assertions | a7e55d1 | CloudFolderRenderedFlow.test.js |
 ## What Was Built
 ### Task 1: Store-Backed Health and Reconnect UX
 **`cloudConnections.js` store extensions:**
 - `connectionHealth` ref — centralized map of `{ state, error_code, error_message, checked_at }` keyed by connection UUID (D-12)
 - `VALID_HEALTH_STATES` — translates server health vocabulary to UI-actionable states (`healthy`, `requires_reauth`, `degraded`, `unknown`)
 - `setConnectionHealth(id, data)` — writes to map with validation; consumers (browser and Settings) never translate independently
 - `getConnectionHealth(id)` — read accessor, returns `{ state: 'unknown', ... }` if absent
 - `handleHealthFailure(id, data)` — records failure state + schedules retest via `pendingHealthRetest` Set (D-13 auto-test after failure)
 - `markReconnecting(id)` — downgrades freshness to stale but does NOT clear `browseItems` (D-14 cached metadata preserved)
 - `markReconnectRefreshPending(id)` — sets `reconnectRefreshPending` flag for CloudFolderView to detect
 - `testConnection(id)` — explicit health probe; only callable from user action or post-failure retest, never from navigation
 - `reconnect(id)` — `markReconnecting` + `fetchConnections` + `markReconnectRefreshPending` sequence
 - `connectionsNeedingHealthCheck` computed — identifies connections with null/unknown health for initial test scheduling
 **`StorageBrowser.vue` health banners:**
 ```html
 <!-- Warning / stale state: D-12 health banner -->
 <div data-test="cloud-health-banner" v-if="folderFreshness === 'warning' || folderFreshness === 'stale'">
  <button data-test="reconnect-action" @click="$emit('reconnect')">Reconnect</button>
 </div>
 <!-- Requires-reauth: CONN-02 reauthentication prompt -->
 <div data-test="requires-reauth" v-else-if="folderFreshness === 'requires_reauth'">
  <button data-test="reconnect-action" @click="$emit('reconnect')">Reconnect</button>
 </div>
 ```
 `'reconnect'` added to `emits` declaration so `CloudFolderView` can handle it.
 **`SettingsCloudTab.vue` health diagnostics:**
 - Per-connection `[data-test="connection-health"]` badge with `healthBadgeLabel` / `healthBadgeClasses` reading from store
 - `[data-test="connection-health-detail"]` error message for degraded/reauth states
 - `[data-test="health-warning"]` indicator for DEGRADED connections (D-15)
 - `[data-test="test-connection"]` button calling `handleTestConnection(id)` → `store.testConnection(id)` (D-13)
 - `[data-test="reconnect-connection"]` button for REQUIRES_REAUTH connections
 - Google Drive scope notice: `[data-test="gdrive-scope-notice"]` with explicit "all files in your Google Drive" copy (D-17)
 - `[data-test="gdrive-consent-copy"]` structural marker and `[data-test="confirm-disconnect-copy"]` for test assertions
 ### Task 2: Reactive Rendered-Flow Test Mock
 **Root cause:** `CloudFolderRenderedFlow.test.js` used a static plain-object store mock. When `CloudFolderView` called `setBrowseState({ freshness: 'warning' })`, the mock recorded the call but never updated `folderFreshness`. The health banner in `StorageBrowser` (which reads `folderFreshness` as a prop from `CloudFolderView`) therefore never appeared.
 **Fix:** Replaced static mock store with Vue ref-backed reactive state:
 ```js
 import { ref } from 'vue'
 const _mockFolderFreshness = ref(null)
 vi.mock('../../stores/cloudConnections.js', () => ({
  useCloudConnectionsStore: () => ({
    get folderFreshness() { return _mockFolderFreshness.value },
    setBrowseState(payload) {
      mockSetBrowseState(payload)
      if (payload.freshness !== undefined) _mockFolderFreshness.value = payload.freshness
      // ... other reactive fields
    },
    // ...
  }),
 }))
 ```
 This propagates freshness state through `CloudFolderView`'s template binding (`:folder-freshness="cloudStore.folderFreshness"`) into `StorageBrowser`'s `folderFreshness` prop, triggering the health banner.
 **Also added `testCloudConnection` to the API mock** so `no_health_probe_on_folder_navigate_D13` can import and assert it was never called.
 ## Test Suite Results
 ```
 429 passed (48 test files)
 ```
 Previous baseline (Plan 09): 429 passed (frontend tests unchanged by Plan 09's backend work)
 - 11 rendered-flow tests: all pass (3 were failing RED, now GREEN)
 - 59 store/Settings/CloudFolderView tests: all pass (were already GREEN from prior implementation)
 - Net: 0 new tests needed (existing RED tests made GREEN by implementation)
 ## Deviations from Plan
 ### Auto-fixed Issues
 **1. [Rule 1 - Bug] Rendered-flow test mock store not reactive**
 - **Found during:** Task 2 (GREEN verification)
 - **Issue:** The mock store returned by `useCloudConnectionsStore` in `CloudFolderRenderedFlow.test.js` used a plain object with a static `folderFreshness: null`. When `CloudFolderView` called `setBrowseState`, the mock recorded the call but `folderFreshness` never updated. The health banner relies on `cloudStore.folderFreshness` being non-null.
 - **Fix:** Used Vue `ref` for `_mockFolderFreshness`, `_mockLastRefreshedAt`, `_mockCapabilities`, `_mockByteAvailability`. The mock's `setBrowseState` now calls `mockSetBrowseState(payload)` (for assertion recording) AND updates the reactive refs. Added `beforeEach` reset of refs for test isolation.
 - **Files modified:** `frontend/src/views/__tests__/CloudFolderRenderedFlow.test.js`
 - **Commit:** a7e55d1
 **2. [Rule 3 - Blocking] testCloudConnection missing from rendered-flow API mock**
 - **Found during:** Task 2 (running tests)
 - **Issue:** `no_health_probe_on_folder_navigate_D13` test imported `testCloudConnection` from the mocked `../../api/client.js`, which threw `[vitest] No "testCloudConnection" export is defined on the mock`.
 - **Fix:** Added `testCloudConnection: vi.fn()` to the `vi.mock('../../api/client.js', ...)` factory in `CloudFolderRenderedFlow.test.js`. Also added `openCloudFile`, `downloadCloudFile`, `uploadCloudFile` to match imports used by `CloudFolderView`.
 - **Files modified:** `frontend/src/views/__tests__/CloudFolderRenderedFlow.test.js`
 - **Commit:** a7e55d1 (same fix commit)
 ## Known Stubs
 None. All health, reconnect, and no-probe behavior is functionally implemented and test-verified. The shared browser surfaces cloud health state through the StorageBrowser component without a second browser or parallel layout.
 ## Threat Flags
 No new security surfaces introduced. Threats mitigated:
 - **T-13-30 (health UX):** Store and Settings tests confirm auto-test only on connect/reconnect/failure; rendered-flow tests confirm no probe fires on navigation.
 - **T-13-31 (destructive cloud actions):** Rendered-flow tests confirm Reconnect and requires-reauth prompts are shown. Invalid-destination and delete-disclosure behavior is handled by backend (Plan 09) and surfaced through props/events in the shared browser.
 - **T-13-32 (broader scope consent):** `[data-test="gdrive-scope-notice"]` and explicit "all files in your Google Drive" copy confirmed in SettingsCloudTab.health.test.js.
