The OCR matcher already returned text similarity confidence but threw away Tesseract's own word confidence data. Preserve the existing confidence semantics for compatibility, attach an averaged ocr_confidence to each match, and lock the parsing and aggregation behavior with focused unit tests. Constraint: existing callers already depend on confidence meaning text similarity Rejected: Rename confidence to text_confidence | would break current match consumers Confidence: high Scope-risk: narrow Reversibility: clean Directive: Keep confidence mapped to text similarity unless a major-version API change is planned Tested: python -m pytest packages/recognition/tests/python/test_ocr_confidence.py -q -p no:cacheprovider --no-cov Not-tested: End-to-end OCR against a local Tesseract binary
