## Detailed Requirement Traceability Matrix (R1 – R4)

### R1. Modern Drag-and-Drop Ingestion & Batch Upload
- **High-Visibility Dropzone**: Global backdrop overlay on window dragover + dedicated dropzone card with laser scanline animations.
- **Batch File Queue**: Supports PDF, PNG, JPEG, and WebP ingestion with instant thumbnail previews (blob URLs) and PDF document icons.
- **Progress States**: Smooth transitions across `queued` $\rightarrow$ `preprocessing` (25%) $\rightarrow$ `uploading` (50%) $\rightarrow$ `extracting` (75%) $\rightarrow$ `success` (100%).
- **Error Boundaries & Isolation**: Corrupt or oversized (>30MB) files fail independently without halting the batch queue.
- **Quick Actions**: Per-file retry mechanism and item removal with automatic worker slot reclamation.
- **Concurrency Control**: Strict $\le 2$ active worker limit enforced across bursts of up to 50 files.

### R2. Side-by-Side Receipt Inspector & Split Review Modal
- **50/50 Dual-Pane Split Layout**: Document viewer on LEFT, editable data fields on RIGHT.
- **DocumentViewer Transform Engine**: CSS transform Zoom (0.25x – 5.0x), Pan (mouse drag / trackpad), 90° CW rotation, and fit-to-page calculation.
- **2-Way Bounding Box Synchronization**: Interactive SVG/CSS overlay highlights receipt regions on hover/click and pulses corresponding bounding boxes when form fields gain focus.
- **Dynamic LineItemsEditor**: Itemized table supporting inline edits of description, quantity, unit price, total price, and tax rate, with automated $qty \times unitPrice = price$ calculation and cross-sum discrepancy verification against receipt gross.
- **Field Audit Badges & 1-Click Revert**: Visual badges distinguish "AI Extracted (X%)" from "Manually Edited" values, with instant 1-click restore to original AI extraction.
- **Real-Time Recalculation**: Editing Gross dynamically updates Net amount and proportional tax breakdown without breaking math consistency.
- **Debounced IndexedDB Auto-Save**: Background persistence with real-time saving status indicators (`saving` $\rightarrow$ `saved`).
- **Navigation & Mobile Support**: Next / Previous receipt navigation with Alt+Arrow hotkeys, and mobile dual-tab switching (`[Beleg-Bild]` vs `[Extrahierte Daten]`).

### R3. Interactive Live Table with Inline Editing & Batch Operations
- **3-Tier StatusBadges**:
  - `Scanned` (Emerald): Valid math, high confidence, no review flags.
  - `Pending Review` (Amber): Low confidence, math deviation, or flagged field needing review.
  - `Confirmed` (Slate/Blue): User-confirmed record (`userConfirmed: true`).
- **Floating BatchActionBar**:
  - Bulk Export to Excel (`.xlsx` dual-sheet with `=SUM()` formulas), accounting CSV (UTF-8 BOM, semicolon delimiters, CRLF), and JSON.
  - Bulk Categorize across selected receipt IDs.
  - Bulk Status Update (mark all as Confirmed).
  - Bulk Delete with confirmation dialog.
- **FilterChipsBar & useReceiptFilters**:
  - Temporal ranges (Today, This Week, This Month, This Year, All).
  - Status filters, Category filters, Amount range bounds (Min/Max).
  - Multi-field search query (merchant, address, receipt number, date, items).
- **LiveTable Affordances**: Inline cell editing with dotted affordances, keyboard spreadsheet navigation (Enter, Tab, Escape, Arrows), and human-edited indicators.

### R4. Accessible Information Hierarchy & Responsive Design
- **Responsive Navigation**: Desktop fixed Sidebar (`hidden md:flex`) and mobile Drawer (`block md:hidden`) triggered via TopNav hamburger button, with ESC key dismiss, backdrop dismiss, and ARIA attributes.
- **TopNav Breadcrumbs**: Dynamic view hierarchy indicator, CMD+K Spotlight search trigger, system status nominal indicator, and bilingual switch (DE/EN).
- **Interactive KPI Cards**:
  - `Total Scanned`: Gross volume, Net volume, Total count, Verified count. Click resets all filters.
  - `Monthly Spend`: Current billing period spend in € and 19%/7% VAT breakdown. Click toggles monthly filter.
  - `Pending Reviews`: Count of items needing attention. Click toggles pending filter.
  - `Average Accuracy`: Dynamic accuracy percentage (e.g. 99.2%) calculated from AI confidence, math checks, and user confirmations, with visual indicator bar and tiered badges (Optimal, High, Medium, Low).
- **WCAG AA Compliance**: All text/badge combinations meet or exceed $\ge 4.5:1$ contrast ratio (Black on white: 21:1, Slate on white: 5.2:1, Emerald badge: 5.1:1, Amber badge: 4.8:1).
- **Zero Horizontal Overflow**: `overflow-x-hidden` on main containers and `overflow-x-auto` on data tables prevent clipping across viewports from 320px to 4K displays.
