Why does a Harness source build say HMR requires --expose-internals?

I see --expose-internals is required for HMR service when developing locally. Where should I start?

This answer refers to the version in the original report. Check the controls and behavior in your own version.

Check the branch or tag, then run its documented development script from the repository root, such as pnpm run dev:web. Compare its startup flags with your manual command. If the script fails too, capture the Node version, invocation, and first stack trace.
