 # Changelog
 
+## 2026-01-16 - 1.4.0 - feat(invoices)
+add hybrid OCR + vision invoice/document parsing with PaddleOCR, consensus voting, and prompt/test refactors
+
+- Add hybrid pipeline documentation and examples (PaddleOCR + MiniCPM-V) and architecture diagram in recipes/document.md
+- Integrate PaddleOCR: new OCR extraction functions and OCR-only prompt flow in test/test.node.ts
+- Add consensus voting and parallel-pass optimization to improve reliability (multiple passes, hashing, and majority voting)
+- Refactor prompts and tests: introduce /nothink token, OCR truncation limits, separate visual and OCR-only prompts, and improved prompt building in test/test.invoices.ts
+- Update image conversion defaults (200 DPI, filename change) and add TypeScript helper functions for extraction and consensus handling
+
+## 2026-01-16 - 1.3.0 - feat(paddleocr)
+add PaddleOCR OCR service (Docker images, server, tests, docs) and CI workflows
+
+- Add GPU and CPU PaddleOCR Dockerfiles; pin paddlepaddle/paddle and paddleocr to stable 2.x and install libgomp1 for CPU builds
+- Avoid pre-downloading OCR models at build-time to prevent build-time segfaults; models are downloaded on first run
+- Refactor PaddleOCR FastAPI server: respect CUDA_VISIBLE_DEVICES, support per-request language, cache default language instance and create temporary instances for other languages
+- Add comprehensive tests (test.paddleocr.ts) and improve invoice extraction tests (parallelize passes, JSON OCR API usage, prioritize certain test cases)
+- Add Gitea CI workflows for tag and non-tag Docker runs and release pipeline (docker build/push, metadata trigger)
+- Update documentation (readme.hints.md) with PaddleOCR usage and add docker registry entry to npmextra.json
+
 ## 2026-01-16 - 1.2.0 - feat(paddleocr)
 add PaddleOCR support: Docker images, FastAPI server, entrypoint and tests

+      "box": [[x1,y1], [x2,y2], [x3,y3], [x4,y4]]
+    }
+  ]
+}
+```
+

+## Why Hybrid?
+
+| Approach | Accuracy | Speed | Best For |
+|----------|----------|-------|----------|
+| VLM Only | 85-90% | Fast | Simple layouts |
+| OCR Only | N/A | Fast | Just text extraction |
+| **Hybrid** | **91%+** | Medium | Complex invoices |
+
+The hybrid approach provides OCR text as context to the VLM, improving accuracy on:
+- Small text and numbers
+- Low contrast documents
+- Dense tables
+
+## Services
+
+| Service | Port | Purpose |
+|---------|------|---------|
+| PaddleOCR | 5000 | Text extraction |
+| Ollama (MiniCPM-V) | 11434 | Intelligent parsing |
+
+## Running the Containers
+
+**Start both services:**
+
+```bash
+# PaddleOCR (CPU is sufficient for OCR)
+docker run -d --name paddleocr -p 5000:5000 \
+  code.foss.global/host.today/ht-docker-ai:paddleocr-cpu
+
+# MiniCPM-V 4.5 (GPU recommended)
+docker run -d --name minicpm --gpus all -p 11434:11434 \
+  -v ollama-data:/root/.ollama \
+  code.foss.global/host.today/ht-docker-ai:minicpm45v
+```
 
 ## Image Conversion
 
-Convert PDF to PNG at 300 DPI for optimal OCR accuracy.
+Convert PDF to PNG at 200 DPI:
 
 ```bash
-convert -density 300 -quality 100 input.pdf \
+convert -density 200 -quality 90 input.pdf \
   -background white -alpha remove \
-  output-%d.png
+  page-%d.png
 ```
 
-**Parameters:**
-- `-density 300`: 300 DPI resolution (critical for accuracy)
-- `-quality 100`: Maximum quality
-- `-background white -alpha remove`: Remove transparency
-- `output-%d.png`: Outputs page-0.png, page-1.png, etc.
+## Step 1: Extract OCR Text
 
-**Dependencies:**
-```bash
-apt-get install imagemagick
+```typescript
+async function extractOcrText(imageBase64: string): Promise<string> {
+  const response = await fetch('http://localhost:5000/ocr', {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify({ image: imageBase64 }),
+  });
+
+  const data = await response.json();
+  if (data.success && data.results) {
+    return data.results.map((r: { text: string }) => r.text).join('\n');
+  }
+  return '';
+}
 ```
 
-## Prompt
+## Step 2: Build Enhanced Prompt
 
-```
-You are a bank statement parser. Extract EVERY transaction from the table.
+```typescript
+function buildPrompt(ocrText: string): string {
+  const base = `You are an invoice parser. Extract the following fields:
 
-Read the Amount column carefully:
-- "- 21,47 €" means DEBIT, output as: -21.47
-- "+ 1.000,00 €" means CREDIT, output as: 1000.00
-- European format: comma = decimal point
+1. invoice_number: The invoice/receipt number
+2. invoice_date: Date in YYYY-MM-DD format
+3. vendor_name: Company that issued the invoice
+4. currency: EUR, USD, etc.
+5. net_amount: Amount before tax (if shown)
+6. vat_amount: Tax/VAT amount (0 if reverse charge)
+7. total_amount: Final amount due
 
-For each row output: {"date":"YYYY-MM-DD","counterparty":"NAME","amount":-21.47}
+Return ONLY valid JSON:
+{"invoice_number":"XXX","invoice_date":"YYYY-MM-DD","vendor_name":"Company","currency":"EUR","net_amount":100.00,"vat_amount":19.00,"total_amount":119.00}`;

 ## Tips
 
-1. **DPI matters**: 150 DPI causes missed rows; 300 DPI is optimal
-2. **PNG over JPEG**: PNG preserves text clarity better
-3. **Remove alpha**: Some models struggle with transparency
-4. **Multi-page**: Pass all pages in single request for context
+1. **Use hybrid approach**: OCR text dramatically improves number/date accuracy
+2. **Consensus voting**: Run 2-5 passes to catch hallucinations
+3. **200 DPI is optimal**: Higher doesn't help, lower loses detail
+4. **PNG over JPEG**: Preserves text clarity
 5. **Temperature 0.1**: Low temperature for consistent output
-6. **European format**: Explicitly explain comma=decimal in prompt
+6. **Multi-page support**: Pass all pages in single request for context
+7. **Normalize for comparison**: Ignore case/whitespace when comparing invoice numbers
+
+## Common Issues
+
+| Issue | Cause | Solution |
+|-------|-------|----------|
+| Wrong date | Multiple dates on invoice | Be specific in prompt about which date |
+| Wrong currency | Symbol vs code mismatch | OCR helps disambiguate |
+| Missing digits | Low resolution | Increase density to 300 DPI |
+| Hallucinated data | VLM uncertainty | Use consensus voting |
