AbstractProtected Optional_Optional provider override; falls back to Metadata.Provider when not set.
Optional ReadonlyIsTrue when items are pushed into this source on demand (such as AutotagUpload) rather than
pulled by walking an external listing. Discover and Sync skip push-only sources with a Skipped
outcome and never mark their items as orphans.
Optional ReadonlySupportsTrue when a driver's walk with Since = null is guaranteed to visit every live top-level item in the
source, so Discover in Mode: 'Sync' can safely mark unvisited items for deletion. Drivers backed by
bounded/windowed feeds (like RSS) leave this unset or false.
ProtectedProviderReturns the active provider — explicit override if set, otherwise the global default.

ContentSourceType.DriverClass).Legacy autotagger drivers implement Autotag and SetContentItemsToProcess; pipeline drivers implement Discover and optionally Fetch (new pipeline-only drivers do not need to override the legacy methods).
