Versioning
Read this before you take a hard dependency on the surface. It says what will never change and how to detect what has been added.
sliick.FilesApi is a managed-package global surface: once a version containing
it is promoted, signatures and error codes are locked. The surface only grows -
new methods, new optional request/result fields, new Callable and Flow actions.
getCapabilities returns the current actions list and a revision that
increments with each addition. The surface is at revision 3: revision 2
added the active-provider default for listFiles and its
includeAllProviders opt-out; revision 3 added getStorageReadiness, a
Callable-only readiness check for relocation.
The full field-by-field reference ships in the package docs.
