Buy the grammar, own the execution: @yarnpkg/parsers parses the command line - aliased at bundle time to its shell entry so the root barrel's syml/js-yaml closure stays out of the worker - and a VFS-backed evaluator with a coreutils command table runs it inside the worker host. Each shell process is a real child WebWorker spawned from the same bundle (the first frame decides the role), so the TERM-then-KILL ladder is real - TERM requests, KILL terminates the worker - and the file face stays asynchronous end to end, since the deployment target serves no COOP/COEP headers and SharedArrayBuffer never exists there. node:child_process reports through the ChildProcess surface the subprocess service consumes; execSync, execFileSync and fork refuse, and node-pty stays stubbed.

* The worker bundle's module proxy table: the ONLY platform fork of the host

* tree. Every entry replaces a Node builtin or an external npm package;
|
|
* workspace and vendored modules are always mounted as they ship.
|
|
*
|
|
* The build turns these into bundler aliases, and `node/builtins.ts` turns the
|
|
* same modules into the loader's static table — one list, two consumers.
|
|
*
|
|
* The replacement path states the classification. `./node/builtin_modules/implemented/<module>.ts`
|
|
* carries the module's real semantics over a worker-side data source (VFS, the
|
|
* tunnel, a wasm codec, a browser primitive); `./node/builtin_modules/mock/<module>.ts` is a
|
|
* structural placeholder that mounts silently and reports the missing capability
|
|
* when a call finally reaches it. External npm replacements live in
|
|
* `./externals/`, named after the package they stand in for.
