### Upstream Repository

The canonical upstream repository for Vampiro One was identified at **https://github.com/SorkinType/Vampiro**, maintained by Sorkin Type. The repository contained a UFO source directory (`Vampiro.ufo`) at the root level, confirming it as a valid open-source font source.

### Source Files

The repository contained:
- `Vampiro.ufo/` — UFO source directory (primary source)
- `Vampiro.vfb` — legacy FontLab source (not used)
- `src/` — additional legacy sources (VFB and SFD, not used)
- `Vampiro.ttf` — compiled TTF output

The UFO source was identified as the canonical source, as it is the modern, open-format version of the font. The VFB and SFD files in `src/` were legacy format files and were not considered as primary sources per policy.
