## Discovery and preview API
Work package 6 now qualifies the [development API and target adapter](preview-target-fixtures.md) against real classpath/module-path fixtures. Session cleanup is cooperative; a fresh target JVM is required to release NeitzelLib process-wide Model/ViewModel state.
Metadata listing must not construct Models or invoke Controller methods. Separate example descriptors (stable IDs, display labels, compatible Model/View information and declared capabilities) from runtime construction. Generated descriptor metadata or equivalent non-constructing discovery must be tested; calling arbitrary provider initialization merely to list examples does not satisfy this boundary.
Selecting an example creates a fresh owned preview session with its Model graph and explicitly configured services. Provide readiness and cleanup hooks. Ordinary examples become ready after load/CSS/layout; asynchronous examples signal readiness subject to cancellation/timeout. Construction, services, Controller actions and cleanup execute only in the target JVM. Verify the adapter against NeitzelLib's actual injection/loading lifecycle before publishing Java signatures.
