Research notes and papers, mostly produced as a byproduct of building phantasm — a content-adaptive JPEG steganography tool in Rust. The site doubles as a long-form notebook and a paper-publishing surface.
If you want the tool itself, go to phantasm.byexec.com. If you want the source, github.com/exec/phantasm. If you want to read what came out of building it, you’re in the right place.

About
Hi, I’m Dylan (exec). I publish research-grade work here when it’s
worth more than a README footnote — typically post-mortems, reproducibility
artifacts, and the occasional paper. Most of what’s here is also reproducible
from the public phantasm repo and its companion
research-checkpoints-v1
release.
