request, SSE, RPC, and socket share a consistent model for targets, context, errors, and reliability.

request, SSE, RPC, and socket are planned product capabilities; the current package only provides the manifest.

VextJS is the first target consumer, while commflow core stays framework-agnostic.

Each communication style, configuration, reliability, troubleshooting, and VextJS adoption has a focused user chapter.

The package is published as `commflow` and currently targets Node.js 20 or newer.

The project is open source and published under the Apache-2.0 license.
