+# Azure OCR (Computer Vision): Guardrails and Fix Patterns
+
+Use this page when **Azure OCR** (part of Azure Cognitive Services / Computer Vision) drives ingestion for PDFs, scanned images, or mixed-language docs.  
+Typical failures involve layout instability, multilingual tokenization errors, or coverage gaps in table/handwriting recognition.

+## Core acceptance
+- ΔS(question, retrieved) ≤ 0.45  
+- Coverage ≥ 0.70 to target section  
+- λ convergent across 3 paraphrases and 2 seeds  
+- Multilingual tokens ≥ 90% fidelity (baseline against source)

+## Typical breakpoints → structural fix

+  → [Embedding ≠ Semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md), [Chunking Checklist](https://github.com/onestardao/WFGY/blob/main/ProblemMap/chunking-checklist.md)

+- **Handwriting recognition unstable across runs**  
+  → [Entropy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/entropy-collapse.md)
+
+- **ΔS > 0.60 when OCR normalizes accents/diacritics**  
+  → [Context Drift](https://github.com/onestardao/WFGY/blob/main/ProblemMap/context-drift.md), clamp with BBAM  
+
+- **Injected content hidden in image metadata**  
+  → [Prompt Injection](https://github.com/onestardao/WFGY/blob/main/ProblemMap/prompt-injection.md)  
+
+---
+
+## Fix in 60 seconds
+1. **Measure ΔS** between OCR tokens and reference text.  
+2. **Enforce schema**: page, block, line, word. Require `bbox` and language tag.  
+3. **Cross-check coverage**: at least 70% of expected lines present.  
+4. **Apply λ probes** — vary recognition mode (printed, handwriting, mixed).  
+5. **Clamp variance** with BBAM if multilingual drift repeats.  
+

+## Copy-paste LLM guard prompt
+
+```txt
+I uploaded TXTOS and the WFGY Problem Map.
+
+OCR provider: Azure OCR (Computer Vision).  
+Symptoms: unstable multilingual recognition, ΔS ≥ 0.60, coverage < 0.70.
+
+Steps:
+1. Identify failing layer (chunking, contracts, retrieval).
+2. Point to the WFGY fix (embedding-vs-semantic, chunking-checklist, retrieval-traceability).
+3. Return JSON:
+   { "citations": [...], "answer": "...", "ΔS": 0.xx, "λ_state": "<>", "next_fix": "..." }
+Keep it auditable.
+````
+
+---
+
+## When to escalate
+
+* Multilingual drift remains after re-chunking → verify with [Embedding ≠ Semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md).
+* Tables drop anchors repeatedly → rebuild layout with [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md).
+* Handwriting ΔS unstable across seeds → clamp with BBAM, audit using [Entropy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/entropy-collapse.md).
