# Document AI & OCR — Global Fix Map

A hub to stabilize OCR and document AI pipelines across providers and open-source stacks.  
Use this folder to jump to guardrails, check common breakpoints, and apply structural fixes with measurable targets.

## When to use this folder

- OCR extracts text but misses table alignment or field boundaries.  
- High word recall but wrong semantic grouping.  
- Citations mismatch scanned sections.  
- Layout-aware models drift when format changes.  
- Two-column or rotated pages break retrieval.  
- Cloud OCR service gives inconsistent JSON schema across runs.  

---

## Acceptance targets for any OCR system

- ΔS(question, extracted text) ≤ 0.45  
- Field/section coverage ≥ 0.70  
- λ remains convergent across 3 paraphrases and 2 seeds  
- E_resonance flat over long document windows

- **Cold boot / wrong version OCR model**

  → [predeploy-collapse.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/predeploy-collapse.md)

- **Hybrid OCR (vision + text) worse than single mode**

## 60-second fix checklist

1. Run OCR twice with different seeds / providers. Compare ΔS and λ.  
2. Validate JSON schema consistency: enforce fields `{page_id, bbox, text, confidence}`.  
3. Apply de-rotation and multi-column split before embedding.  
4. Check coverage ≥ 0.70 on a gold page.  
5. Enforce cite-then-explain in downstream reasoning.
