+# ATDD Checklist - Epic 3: "My Legacy" - History, Offline Sync & PWA Polish
+
+**Date:** 2026-01-23
+**Author:** Max
+**Primary Test Level:** Integration
+
+---
+
+## Story Summary
+
+Implement History Feed with Offline Sync capabilities and PWA polish. Users need to access their chat history offline, delete entries, and have changes synced when back online.
+
+**As a** User
+**I want** to access and manage my chat history offline
+**So that** I don't lose context or data when connection drops
+
+---
+
+## Acceptance Criteria
+
+1. Offline actions (save, delete) are queued when network is unavailable.
+2. Queue is replayed automatically when connection is restored.
+3. Deleting an entry removes it from UI immediately (optimistic) and persists to DB.
+4. Initial load shows empty state for new users.
+
+---
+
+## Failing Tests Created (RED Phase)
+
+### Integration Tests (4 tests)
+

+- ✅ **Test:** should enqueue SAVE_DRAFT action when offline
+  - **Status:** RED - Expected true to be false
+  - **Verifies:** Action is added to Dexie 'syncQueue' table
+- ✅ **Test:** should enqueue DELETE_ENTRY action when offline
+  - **Status:** RED - Expected true to be false
+  - **Verifies:** Delete action is queued
+
+**File:** `tests/integration/sync-action-replay.test.ts`
+- ✅ **Test:** should process pending actions when network restores
+  - **Status:** RED - Expected true to be false
+  - **Verifies:** Queue is processed and API called
+
+**File:** `tests/integration/deletion-persistence.test.ts`
+- ✅ **Test:** should permanently remove item from Dexie DB
+  - **Status:** RED - Expected true to be false
+  - **Verifies:** Data is removed from IndexedDB
+
+### Component Tests (1 test)
+
+**File:** `tests/component/DeleteEntryDialog.test.tsx`
+- ✅ **Test:** should show dialog and optimistically remove item from UI on confirm
+  - **Status:** RED - Expected true to be false
+  - **Verifies:** UI interaction and callback
+
+### E2E Tests (1 test)
+
+**File:** `tests/e2e/initial-load.spec.ts`
+- ✅ **Test:** should render empty state history feed for new user
+  - **Status:** RED - Element not found
+  - **Verifies:** Empty state UX
+
+---
+
+## Data Factories Created
+
+**File:** `tests/support/factories/history-entry.factory.ts`
+
+- `createChatSession(overrides?)` - Random chat session
+- `createChatSessions(count)` - Array of sessions
+
+## Fixtures Created
+
+**File:** `tests/support/fixtures/offline.fixture.ts`
+
+- `offline` - Offline simulation
+  - `goOffline(context)` - Disables network and dispatches events
+  - `goOnline(context)` - Restores network
+
+**File:** `tests/support/fixtures/db.fixture.ts`
+
+- `db` - IndexedDB Helpers
+  - `resetDb()` - Clears database
+  - `seedHistory(data)` - Seeds initial data
+
+---
+
+## Implementation Checklist

+
+- [ ] Implement `processQueue` method in SyncManager
+- [ ] Add network event listeners

+
+---
+
+## Red-Green-Refactor Workflow
+
+### RED Phase (Complete) ✅
+
+- ✅ All tests written and failing
+- ✅ Fixtures and factories created
+- ✅ Implementation checklist created
+
+### GREEN Phase (DEV Team - Next Steps)
+
+1. **Pick one failing test** from checklist
+2. **Implement minimal code** to make it pass
+3. **Run the test** to verify green
