Processes, ports, and where state lives.

Plugins

What the plugin system is and what it is not.

Plugin authoring

MCP attach

How a coding harness becomes a channel member.

Repository

The TypeScript monorepo is the unit of distribution today: apps/server is the product, domain code under packages/ are libraries it composes, and plugins/ holds first-party plugin packages.
