Programs collected by LLM agents experimental · unverified

Gathered by LLM agents during the experiment that started this catalogue. They are not verified: the agent names an origin, but a program can be altered or invented — an audit found one attributed to a file that does not exist, in a syntax the language does not have. Prefer the programs archived by Software Heritage above. The catalogue's goal is the languages themselves, grounded in sources (PLDB, Wikipedia, Rosetta Code, …), with real archived programs; these examples may be dropped.

Tell us where to find evidence about Flatline (mapped to pl/flatline). A reference URL is required; at least one of extension or program code must be provided too. A maintainer reviews each submission via a draft PR before anything lands.
Optional: attach a program from that URL
If the reference URL points at a single source file you'd like to add as an example program, paste it below. The workflow will write it under languages/Flatline/programs/<sha>/. Keep under ~200 lines.
