# Source architecture

The canonical guide is now [CLI architecture — 2server](https://2found.dev/docs/2server/architect-cli/index.md).
It covers module/layer ownership, command routing, configuration and credentials,
plan/apply lifecycle, extension contracts and verification.

This page preserves the previous documentation URL. Update contributor and
integration references to `docs/ARCHITECT-CLI.md`; keep architecture rules in
that one guide.
