+# Phase 10 Plan 02: EmptyState Component Summary
+
+**One-liner:** Options API `EmptyState.vue` with icon/headline/subtext/size props and named `#cta` slot, replacing all inline "no items" text patterns across 5+ views.
+
+## What Was Built
+
+`EmptyState.vue` is a shared, props-driven empty-state component that consolidates the "nothing here" pattern used across StorageBrowser, SharedView, CloudStorageView, AppSidebar, and AdminAuditView into a single reusable component.
+
+**Props:**
+- `icon` (String, default null) — AppIcon registry name
+- `headline` (String, required) — main message
+- `subtext` (String, default '') — secondary description
+- `size` (String, default 'md') — 'sm' for sidebar micro states, 'md' for centered full layout
+
+**Size variants:**
+| size | container | icon | subtext |
+|------|-----------|------|---------|
+| md | `text-center py-10 px-4` | `w-8 h-8 mx-auto mb-3 text-gray-300` | visible |
+| sm | `flex items-center gap-2 py-1 text-xs text-gray-400` | `w-3.5 h-3.5 shrink-0` | hidden |
+
+**Named `#cta` slot** renders nothing when empty; used by CloudStorageView for the Settings link.
+
+## TDD Compliance
+
+| Gate | Commit | Status |
+|------|--------|--------|
+| RED — 7 failing tests | 96f4b5f | PASS |
+| GREEN — all 7 tests pass | e56d17e | PASS |
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Created AppIcon.vue to unblock EmptyState.vue import resolution**
+- **Found during:** Task 2 (GREEN)
+- **Issue:** `EmptyState.vue` imports `./AppIcon.vue` at the module level. Vite's import-analysis plugin fails to transform `EmptyState.vue` during test runs when `AppIcon.vue` does not exist, even though tests stub the component via `global.stubs: { AppIcon: true }`. The stub operates at runtime but module resolution is at transform time.
+- **Fix:** Created `frontend/src/components/ui/AppIcon.vue` from the exact content specified in `10-PATTERNS.md §AppIcon.vue`. Content is byte-for-byte identical to what plan 10-01 would create.
+- **Impact:** None — plan 10-01 (parallel wave 0 agent) creates the same file. If both agents commit, the second commit will be a no-op (identical content). Git merge will see no conflict.
+- **Files modified:** `frontend/src/components/ui/AppIcon.vue` (created)
+- **Commit:** e56d17e
