Filtering Pipeline
- OCR cleanup — removal of OCR artifacts, boilerplate, and unicode normalization
- Quality filtering — token frequency prior-based filtering as a cheap proxy for perplexity
- Anachronism detection — three-tier post-1900 physics filter to remove mislabeled modern texts:
- Always reject: unambiguous post-1900 terms (photon, spacetime, transistor, etc.)
- Date reject: documents with 5+ explicit post-1900 year references
- Context reject: 3+ co-occurring ambiguous terms (quantum, nuclear, radiation, etc.)
