Plugins

14. Plugins — the extensibility law

A plugin is a function that receives the app, adds capabilities, and returns it with accumulated types. A plugin may contribute: flows, hooks, context decorations, elements, drivers, image recipes, DB schema, typed errors, client extensions, CLI commands, and Console panels.

Guarantee: every built-in feature — auth, Console, docker derivation, channels — uses only the public plugin API. If the core team ever needs a private hook, the API is broken and gets fixed.
