PR #9499, merged August 23 and released in 0.22.2, is a breaking change moving the session-persistent REPL from three built-in packages/core tools into a new @qwen-code/node-repl-mcp package, opt-in through mcpServers (GitHub). It exposes node_repl, node_repl_reset and node_repl_add_node_module_dir over stdio; each call evaluates a fresh vm.SourceTextModule with prior bindings threaded in via an @prev SyntheticModule, so object identity, closures and declaration kinds survive between cells. The stated reason is architectural: packages/core stays byte-identical to main and the net diff is the new package plus two wiring lines. That's what a clean extraction looks like.
