# Research Source Library

This directory contains full local copies of open research sources reviewed for Humanizer. PDFs are stored in their published form; two PubMed Central articles are stored as full-text XML because the PMC PDF endpoint returned an interstitial rather than the paper.

## Sources linked but not copied locally

- Huang et al., “Wikipedia in the Era of LLMs: Evolution and Risks”: https://openreview.net/forum?id=ahVmnYkVLt — OpenReview blocked automated PDF retrieval during this build.
- Paywalled journalism, magazine features, and proprietary style manuals in `source-bibliography.md` remain links rather than local copies.

## Integrity

`SHA256SUMS` records the downloaded file hashes. Regenerate it after deliberately updating a source snapshot.
