# Phase 06.2 Plan 05: Close Four UAT-Diagnosed UI Gaps Summary

**One-liner:** Four targeted frontend changes that make user handles visible, cloud storage errors actionable, audit log handles correctly prefixed with @, and CSV export scope transparent.

## What Was Built

Closed all four UAT-diagnosed UI gaps from 06.2-UAT.md with template-only and minimal script changes across four Vue components. No backend changes were required.

### Gap 1: Handle visibility (SHARE-03)

- **AccountView.vue**: Added "Username" row between Email and Role in the Account information section displaying `@{{ authStore.user?.handle }}` — users can now see and share their own handle
- **AdminUsersTab.vue**: Added "Handle" column (th + td) to the users table showing `@handle` or `—` — admins can look up users' handles for support and sharing

### Gap 2: Actionable cloud connection error (CloudFolderView)

- Updated `load()` catch block to detect "no active connection" / 404 / "not found" errors and replace the generic error message with: "No cloud provider connected. Go to Settings to connect a cloud storage account."
- Updated error template block to show a `router-link` to `/settings` (Go to Settings) plus a Retry button, replacing the single inline Retry button

### Gap 3: Audit log @ prefix (AuditLogTab)

- Changed the User column cell from `{{ entry.user_handle || entry.user_id || '—' }}` to `{{ entry.user_handle ? '@' + entry.user_handle : (entry.user_id || '—') }}` — entries now display @alice style handles

### Gap 4: Clear filters + active filter count (AuditLogTab)

- Added `clearFilters()` function that resets all four filter fields and re-fetches from page 1
- Added `activeFilterCount` computed property counting non-empty filter fields
- Added "Clear filters" button (v-if visible only when activeFilterCount > 0) after the Apply filters button
- Wrapped Export CSV button in a container that shows "N filter(s) active" in amber text below the button when any filters are set
- Added `computed` to the vue import

## Commits

| Task | Description | Commit |
|------|-------------|--------|
| 1 | Show @handle in AccountView and AdminUsersTab | 045e723 |
| 2 | Actionable cloud error + audit log @ prefix | f5e111b |
| 3 | Clear filters button and active filter count in AuditLogTab | 5d457d6 |

## Verification Results

All plan verification checks pass:

```
Gap 1 - Handle in AccountView: line 12 match
Gap 1 - Handle in AdminUsersTab: lines 115 (th) + 133 (td)
Gap 2 - Cloud actionable error: 2 matches (error.value + Go to Settings link)
Gap 3 - Audit log @ prefix: line 110 match
Gap 4 - clearFilters|activeFilterCount: 6 matches (>= 5 required)
npm run build: exits 0 with no errors
```

## Deviations from Plan

None - plan executed exactly as written.

## Threat Surface Scan

No new security-relevant surface introduced. All four changes render user-supplied data through Vue template auto-escaping (`{{ }}` not `v-html`). The `@ + entry.user_handle` concatenation in the template is auto-escaped. The error message from the cloud API response is similarly template-interpolated. No new network endpoints, auth paths, or schema changes introduced.
