decayfmt Is a File Format That Permanently Damages Itself Every Time You Open It

A r/ClaudeAI post at 1,248 upvotes introduces decayfmt, a file format where every read permanently corrupts the file on disk by an amount encoded in the filename, before the contents are shown, with no recovery possible from the file alone. The repo is at github.com/aravpanwar/decayfmt. It is a toy, but it is the rare vibe-coded project on that subreddit built around a constraint rather than a feature list, and the top-voted post of the day there was this rather than any model news.
