Indexed languages are cross-referenced from languages/**/meta.json (LLM-curated) and seven upstream sources (PLDB, Linguist, Pygments, Wikipedia, Esolang, Hyperpolyglot, Rosetta Code). Each PL page shows which sources mention it, what extensions it claims, and real archived programs from Software Heritage. See Stats for coverage and Extensions catalog for per-extension claimants & heuristics.
