black box testing closed-source software with LLMs. Can they fuzz the space and get a passing approximation of the real thing?
Swap published columns for 24 entries from random.md Retract the seven published columns into drafts/ and promote the 24 per-date entries split out of Notes/random.md. Bodies are verbatim; titles, subjects and slugs are new. Make publication a matter of location. Notes/Notes.11tydata.js gives anything under Notes/ permalink: false unless tagged `column`; drafts/drafts.11tydata.js renders drafts at their real permalink under `yarn dev` and excludes them from collections entirely in a build, so no template can surface one. Publishing is now `git mv drafts/<file> columns/`, and moving it back retracts it. Untagged notes were previously rendered into _site/ and deployed — including Notes/random.md, which was live at /Notes/random/. 2026-08-02 22:45:19 +00:00			`---`
