# HebOCRBench v1 — locked source mirror

This repository is the minimal public transport mirror used to reproduce five
separate HebOCRBench v1 extension and synthetic-diagnostic roots. It contains
only the immutable artifacts selected by the benchmark registry; it does not
mirror the much larger upstream repositories.

The canonical source identities, upstream revisions, provenance, per-source
terms, expected sizes, and SHA-256 values remain in the public
[HebOCRBench registry](https://github.com/office883/HebOCRBench/blob/main/corpora/registry.yaml).
The release workflow downloads these mirror bytes and then verifies them
against those canonical registry checksums before any corpus is built.

The Foundation files are synthetic and support non-rankable niqqud and
single-font Rashi diagnostics. The Parquet file supports the separate modern
handwriting extension. The historical-handwriting TAR contains a larger mixed
upstream shard; HebOCRBench selects only the locked six-page Pinkas subset.
None of these extensions is blended into the Modern Hebrew printed-document
headline score.

HebOCRBench software is MIT-licensed. That software license does not relicense
these data artifacts; consult the registry and upstream provenance before use
or redistribution outside benchmark evaluation.
