These projects only ever got a title, a category and a status — no spec, no version history and no files on the site. They are listed here rather than given a page that would have to invent its own content. Their cards still exist in the portfolio.
Every log is generated from the project’s own build spec (prompts/<name>-prompt.md),
its card data and the files on this site. Reflections live in
