game/module -> program, main -> entry, component -> property, archetype -> model, system -> handler. Done via a transitional self-hosting bootstrap: parser accepts both -> reseed -> compiler source moved to new keywords + parser tightened to new-only -> reseed (fixpoint holds). Old keywords now rejected. Token-safe corpus migration (tools/ludic-tools/rename_kw.c) leaves the LLVM @main/entry: labels in emit strings untouched; goldens byte-identical. Editor vocab (header/JetBrains/TextMate/emacs), check-docs wrapper, and doc fences updated; error string 'unknown component' -> 'unknown property'. test.sh 14/14, test-tools 28/0, check-vocabulary green. (Doc prose pass to follow.) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
