+## `ctx.settings` — `Settings` (abstract seam)

+Abstract settings service. Providers implement raw-document storage (`load`/`persist`) and push external changes through Settings.publish; the base class owns namespace registration, resolution, validation, change detection, and the `settings/updated` commit event.
+
+```ts cordis-catalog
+/**
+ * Register a namespace schema and receive its owner scope. The registration
+ * is an effect on the calling plugin's fiber: disposing that fiber removes
+ * the namespace and its observers. An invalid stored section fails the
+ * registration itself — the earliest point where the schema can judge it.
+ * @param ns - unique namespace; duplicate registration fails loud.
+ * @param schema - schemastery schema resolving this namespace's value.
+ * @param options - composition `base` layer and effect timing.
+ * @returns the owner scope for reads, observation, and updates.

+ * merging over the previous write's committed section.
