Use this page when **ABBYY OCR** powers ingestion of scanned PDFs, complex layouts, forms, or multilingual documents.
ABBYY is enterprise-grade, but still prone to schema drift, field misalignment, and unstable table anchors.

## Core acceptance
- ΔS(question, retrieved) ≤ 0.45
- Coverage ≥ 0.70 across fields and tokens
- λ convergent on three paraphrases and two seeds
- Form fields ≥ 95% aligned with schema contract
---
## Typical breakpoints → structural fix
- **Form fields drift across runs** (invoice totals, line items misaligned)
→ [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md), [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md)
- **Table anchors collapse** (multi-column invoices, receipts)
→ [Chunking Checklist](https://github.com/onestardao/WFGY/blob/main/ProblemMap/chunking-checklist.md), clamp with BBMC
- **Handwriting extraction unstable**
→ [Entropy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/entropy-collapse.md)
- **Injected payload in OCR notes layer**
→ [Prompt Injection](https://github.com/onestardao/WFGY/blob/main/ProblemMap/prompt-injection.md)
- **Multilingual contract fields mismatched**
→ [Embedding ≠ Semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md)

## Fix in 60 seconds
1. Enforce **field schema**: require `field_id`, `bbox`, `confidence`, `revision_id`.
2. Compute ΔS on critical fields (e.g. `total_amount`, `invoice_date`).
3. Apply λ probes with different template libraries.
4. Clamp instability with BBAM and log coverage.
5. Rebuild index if ΔS ≥ 0.60 persists.

## Copy-paste LLM guard prompt
```txt
I uploaded TXTOS and the WFGY Problem Map.
OCR provider: ABBYY (FineReader / FlexiCapture).
Symptoms: field drift, unstable tables, ΔS ≥ 0.60.
Steps:
1. Identify failing layer (contracts, chunking, retrieval).
2. Point to the WFGY fix page.
3. Return JSON:
{ "fields_checked": [...], "answer": "...", "ΔS": 0.xx, "λ_state": "<>", "next_fix": "..." }
Keep it reproducible and auditable.

## When to escalate
* Field coverage < 0.70 even after re-chunk → [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)
* Persistent anchor drift → [Chunking Checklist](https://github.com/onestardao/WFGY/blob/main/ProblemMap/chunking-checklist.md)
* Handwriting ΔS unstable across seeds → [Entropy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/entropy-collapse.md)
