# Superlinked Docling artifacts

This repository is an immutable composite artifact root for Docling's standard
PDF pipeline. It contains only the assets exercised by Superlinked's current
`docling` default and OCR runtime profiles:

- Docling Layout Heron;
- TableFormer in accurate mode; and
- RapidOCR PP-OCRv4 Chinese ONNX detection, classification, and recognition.

The directory layout is the one accepted by Docling's `artifacts_path`. The
snapshot was assembled and validated with Docling 2.99.0. It does not contain
Docling's Python distribution or any Superlinked serving code.

The RapidOCR visualization font is deliberately omitted. It is not required by
the validated inference path; consumers that render RapidOCR visualization
output must supply a suitably licensed font separately.

See `SOURCES.json` for the exact upstream revisions/releases, per-file sizes and
SHA-256 digests, and license evidence. Each upstream component retains its own
license; this composite repository does not relicense those assets.

For SIE, pin the resulting 40-character repository commit as the model's
`hf_revision`. `DoclingAdapter` resolves the snapshot and passes its root to
Docling without a model-specific staging path.
