Pre-composed plugin bundles a thin leaf `cordis.yml` loads instead of assembling the spine and a front door by hand. These are **demo / reference** packages — the `-demo` npm suffix marks each one as non-product surface, readable straight off the package name. The runnable leaves under the repo-root [`examples/`](../../examples/AGENTS.md) and the [Python SDK runtime](../../python/sdk-runtime/README.md) are the consumers; each is just its swappable backends plus one bundle entry.
Do not confuse this group with the repo-root [`examples/`](../../examples/AGENTS.md): that directory holds the runnable `cordis.yml`**leaves**; this group holds the **bundles** those leaves load.
