Defined in: [packages/core/src/domain/schemas/krd/index.ts:39](https://github.com/pablo-albaladejo/kaiord/blob/3eacbe62ef72342d970523967cc5155b5935bb85/packages/core/src/domain/schemas/krd/index.ts#L39)

Tagged shape for KRD `extensions`.

Reserved namespaces are validated when present:

* `structured_workout`, `fit`, `course`, `course_points` carry adapter-
  specific payloads whose shape is narrowed by downstream consumers
  (e.g. the SPA editor's `ui-workout` view).
* `health.<metric>` payloads are validated against the `health-data`
  capability sub-schemas.

`catchall(z.unknown())` keeps unknown adapter-defined namespaces
round-trippable per the extension preservation rule in
`openspec/specs/krd-format`.
