	// RequeueInterval controls how long the reconciler sleeps before
	// retrying after a successful or failed reconcile. Configured via the

	// (SetupWithManager fills the zero value so unit-test constructions

	// SelectorWriteConcurrency bounds the number of in-flight destination
	// writes during selector-based fan-out. Each worker issues a Get plus
	// (optionally) a Create or Update against the apiserver; HTTP/2
	// multiplexing in client-go lets many of these share a single
	// connection, but we cap the parallelism so a Projection matching
	// thousands of namespaces can't DoS the apiserver or blow out
	// controller memory with goroutines. Configured via the
	// --selector-write-concurrency CLI flag (Helm value
	// selectorWriteConcurrency). Defaults to defaultSelectorWriteConcurrency
	// when unset; SetupWithManager fills the zero value so unit-test
	// constructions don't need to set it explicitly, and the fan-out site
	// guards the same default so direct-Reconcile unit tests that bypass
	// SetupWithManager don't deadlock on a zero-capacity semaphore.
	SelectorWriteConcurrency int

	// Controller is the underlying controller.Controller we built in
	// SetupWithManager. We need it so Reconcile can register new source
	// watches lazily as previously-unseen source GVKs show up. It is nil
	// in unit tests that call Reconcile directly without SetupWithManager.
	Controller controller.Controller
	// Cache is the manager's cache, used as the source for dynamic watches.
	// Also nil in direct-reconcile unit tests.
	Cache cache.Cache
	// contains filtered or unexported fields
