Kat57 OCR smoke benchmark results

Exact ground-truth scoring for a 50-card Tesseract integration run over tadad/kat57-ground-truth-smoke. OCR outputs are published in the tesseract config of tadad/kat57-ocr-bench.

Model	CER	WER	Evaluated	Empty outputs	Error sentinels	Skipped references
Tesseract 5	0.4656	0.8605	50	1	0	0

The corpus totals are 4,629 character edits over 9,941 reference characters and 1,221 word edits over 1,419 reference words. Scoring used ocr-bench score in normalized mode: Unicode is canonicalized, known HTML is flattened, and whitespace is collapsed while case and punctuation remain significant.

Configs

metrics: corpus-level CER/WER and auditable numerators/denominators
metric_details: per-card edit counts and scores for all 50 cards
metric_metadata: scoring mode, source, seed, split, and timestamp

Important limitation

This is a pipeline smoke test, not a representative Kat57 benchmark: the 50 cards are ordered rows from the first full-dataset shard. Tesseract used its default English model on multilingual cards containing both print and handwriting, so these scores establish a reproducible baseline rather than a claim about state-of-the-art OCR quality.

Generated with the ground-truth scoring implementation on tadad/ocr-bench:feat/cer-wer-kat57.
