Module docs 

Any-doc bridge — lower PDF / DOCX / PPTX / HTML / MD / TXT to plain text, natively in Rust, so the folder ingest can project every readable document into the hypergraph (not just tabular/text files). The extracted text feeds the same TextEngine (SPO tagger + SPLADE + gazetteer) as .txt.

Text-layer extraction only: scanned/image PDFs (no text layer) yield little — OCR (the bundled PP-OCRv6 models) is the follow-up. Gated behind the docs feature (implies onnx).

Constants

DOC_EXTS

The document extensions this bridge can lower to text.

Functions

extract_text

Extract plain text from a document by extension. Ok(None) = unsupported type; Err = read/parse failure the caller can report and skip.

is_doc_ext

strip_html

Minimal HTML → text: drop <script>/<style> blocks, strip tags, decode common entities, collapse whitespace. Enough for retrieval; not a full renderer.
