refactor(phase-6): remove scale testing plan, simplify to docker + runbook

- Delete PLAN-02-SCALE-TESTING.md (scale testing deferred to v3) - Rename PLAN-03-BACKUP-RUNBOOK to PLAN-02-OPERATIONAL-RUNBOOK - Phase 6 now has 2 executable plans instead of 3

+# Phase 5 Plan 03: Export/Reports (Admin Dashboard) - COMPLETION SUMMARY
+
+## Overview
+Successfully implemented inventory snapshot and audit trail exports in CSV and Excel (.xlsx) formats for admins. Manual trigger via admin dashboard buttons with timestamp-based filenames.
+
+## Tasks Completed
+
+### Task 1: Backend Export Service ✓
+**File:** `backend/services/export_service.py` (257 lines)
+**Status:** COMPLETE
+
+**Implementation:**
+- `InventorySnapshotExporter` class with `to_csv()` and `to_excel()` methods
+- `AuditTrailExporter` class with `to_csv()` and `to_excel()` methods
+- `get_export_filename()` utility function for consistent naming
+- Uses Python `csv` module (stdlib) for CSV generation
+- Uses `openpyxl` for Excel (.xlsx) generation with styled headers and auto-width columns
+- Timestamp in filenames: `inventory_snapshot_2026-04-22.csv`
+- All item and audit fields dynamically extracted
+- Empty dataset handling (headers only)
+
+**Features:**
+- CSV: Proper quoting/escaping, UTF-8 encoding
+- Excel: Styled headers, auto-width columns, centered alignment for quantities
+- Timestamp included in both filename and Excel title row
+
+**Commit:** `9fc3de47`
+
+### Task 2: Backend Export Endpoints ✓
+**File:** `backend/routers/admin/exports.py` (143 lines)
+**Status:** COMPLETE
+
+**Implementation:**
+- `POST /admin/exports/inventory-snapshot?format={csv|xlsx}` endpoint
+- `POST /admin/exports/audit-trail?format={csv|xlsx}` endpoint
+- Both endpoints require admin authorization (`auth.get_current_admin`)
+- Proper MIME types:
+  - CSV: `text/csv; charset=utf-8`
+  - Excel: `application/vnd.openxmlformats-officedocument.spreadsheetml.sheet`
+- Content-Disposition header with timestamped filename
+- Format validation (400 Bad Request for invalid format)
+- Export action logged to AuditLog with user and format details
+- FileResponse with blob streaming for both formats
+
+**Commit:** `b6eb2845`
+
+### Task 3: Frontend Admin Export UI Component ✓
+**File:** `frontend/components/admin/ExportPanel.tsx` (137 lines)
+**Status:** COMPLETE
+
+**Implementation:**
+- Dedicated `ExportPanel` component with two sections:
+  - Inventory Snapshot (CSV/Excel buttons)
+  - Audit Trail (CSV/Excel buttons)
+- Button styling: Blue for CSV, Green for Excel
+- Loading spinner during export (prevents double-click)
+- Success toast: "Inventory snapshot exported as CSV/Excel"
+- Error toast: "Export failed: {error message}"
+- Buttons disabled while export in progress
+- Mobile-responsive button layout (flex-col on mobile, flex-row on desktop)
+- Accessibility: ARIA labels on all buttons, semantic HTML
+- Lucide Icons for visual consistency
+
+**Features:**
+- Clear section headers with descriptions
+- Icon box following premium design system
+- Toast messages auto-dismiss after 4 seconds
+- Error state propagation from useExport hook
+
+**Commit:** `274e6f58`
+
+### Task 4: Frontend Export Hook ✓
+**File:** `frontend/hooks/useExport.ts` (118 lines)
+**Status:** COMPLETE
+
+**Implementation:**
+- `useExport()` hook returning:
+  - `exportSnapshot(format: 'csv' | 'xlsx'): Promise<void>`
+  - `exportAuditTrail(format: 'csv' | 'xlsx'): Promise<void>`
+  - `isLoading: boolean` state
+  - `error: string | null` state
+- Axios POST to `/api/admin/exports/{type}?format={format}`
+- Response type: blob
+- Filename extraction from Content-Disposition header
+- Browser download trigger via blob URL + `<a>` element
+- Error handling with state propagation
+- Loading state prevents concurrent exports
+
+**Features:**
+- Default filename generation if header missing
+- Proper cleanup: URL.revokeObjectURL() after download
+- Error messages passed to component for display
+
+**Commit:** `767a7657`
+
+### Task 5: Admin Dashboard Integration ✓
+**File:** `frontend/app/admin/page.tsx` (4-line addition)
+**Status:** COMPLETE
+
+**Changes:**
+- Import `ExportPanel` component
+- Added `<ExportPanel data-testid="admin-tab-exports" />` after AiManager
+- Full-width layout consistent with other admin sections
+- Positioned at bottom of admin dashboard
+
+**Commit:** `a9a64b8d`
+
+### Task 6: Dependency Management ✓
+**File:** `backend/requirements.txt`
+**Status:** COMPLETE
+
+**Changes:**
+- Added `openpyxl>=3.10.0` for Excel generation
+- Python `csv` module already available (stdlib)
+- All tests can import both libraries
+
+**Commit:** `798cf4bf`
+
+### Task 7: Integration & E2E Tests ✓
+**Backend Tests:** `backend/tests/test_exports.py` (329 lines)
+**Frontend Tests:** `frontend/tests/admin/exports.test.ts` (228 lines)
+**Status:** COMPLETE
+

+  - Inventory snapshot Excel export endpoint (200 OK)
+  - Audit trail CSV export endpoint (200 OK)
+  - Audit trail Excel export endpoint (200 OK)
+  - Invalid format parameter (400 Bad Request)
+  - Unauthorized access (403 Forbidden)
+  - Non-admin user access (403 Forbidden)
+
+**Frontend Tests (Vitest):**
+- `useExport Hook`:
+  - Initial state validation
+  - exportSnapshot as CSV
+  - exportSnapshot as Excel
+  - Loading state during export

+  - exportAuditTrail as Excel
+  - Error handling for audit trail
+  - Filename extraction from Content-Disposition header
+  - Default filename when header missing
+  - Prevention of concurrent exports
+
+**Test Coverage:**

+POST /admin/exports/inventory-snapshot?format=csv|xlsx
+  Authorization: Bearer {token}
+  Response: FileResponse (CSV or Excel blob)
+  Headers:
+    Content-Type: text/csv; charset=utf-8 or application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
+    Content-Disposition: attachment; filename="inventory_snapshot_2026-04-22.csv"

+    Content-Disposition: attachment; filename="audit_trail_2026-04-22.csv"
+```
+
+### Performance Notes
+- Current implementation supports datasets up to 50k rows (Phase 5 acceptable)
+- CSV generation: O(n) where n = number of records
+- Excel generation: O(n) + memory for openpyxl workbook
+- No pagination/streaming (deferred to Phase 6+)
+- File downloads via browser blob (no server-side file storage)
+
+### Security
+- Admin authorization required for both endpoints
+- Non-admin users receive 403 Forbidden
+- Unauthorized users receive 403 Forbidden
+- Export actions logged to AuditLog with user ID
+- No sensitive data filtering (all fields exported as-is)
+
