Entry point 01

Start at the interface.

The public plugin SDK is an MIT-derived, typed contract for extension work. Inspect the manifest and client interfaces, then follow the wider open-source estate.

04Provider choicemodels remain replaceable

Principle 02

Keep the world, not the lock-in.

Arcanea treats repositories, portable context, and explicit model access as product primitives. Your canon remains inspectable, forkable, and yours.
