## 🏛️ Source Data

The source documents were downloaded from the official Department of War UFO/UAP release portal:

- **Portal:** [https://www.war.gov/UFO/](https://www.war.gov/UFO/)
- **Program:** Presidential Unsealing and Reporting System for UAP Encounters (PURSUE)
- **Release:** Release 01 — "Cleared for release - May 8, 2026"
- **Agencies represented:** FBI, NASA, Department of War, Department of State

### Document Types

The 120 PDFs include:
- FBI investigative case files (62-HQ-83894 series)
- Department of War historical records (1946–1955)
- NASA mission transcripts and crew debriefings (Apollo, Gemini, Skylab)
- Department of State diplomatic cables
- Contemporary UAP mission reports (2020–2025)
- Range fouler debriefs and reporting forms
- Photographic evidence (FBI Photo B1–B24)

## 🔧 Processing Steps

1. **Download:** All 120 PDFs were downloaded from `war.gov/medialink/ufo/release_1/` using the official manifest.
2. **Verification:** Each file was verified to start with the `%PDF-` magic bytes and have non-zero size.
3. **Rendering:** Each PDF page was rendered to an image using [PyMuPDF](https://github.com/pymupdf/PyMuPDF) at **200 DPI**.
4. **Encoding:** Images were encoded as **JPEG** with quality determined by the renderer's default settings.
5. **Metadata pairing:** Each page was matched with metadata from the official release manifest (`pdf_manifest.tsv`).
6. **Dataset creation:** Images and metadata were assembled into a Hugging Face `datasets` Dataset and exported as Parquet.
