• src/code now has one folder per language family instead of one per language, so the folder structure matches Family:

  • typescript/ holds the TypeScript reader, its symbol, call and id walks, and Vue;
  • jvm/ holds the shared JVM walk with java/ and kotlin/ inside it;
  • dotnet/ holds csharp/ and razor/.

  Families with a single language keep their existing folder.

• Only paths change. No walk's code changes.

• Stacked on Keep each language's behaviour in one reader table #170, which should merge first.

• cargo clippy --all-targets -- -D warnings — clean
• A 776-file polyglot corpus gives a byte-identical graph.json and headers.json before and after the move
