Orleans 10.2 intentionally requires affirmative trust for every component of a formatted type name, but the migration path for JSON-serialized abstract application types was not clearly documented or covered by the reporter's exact scenario.
This change adds focused
IReadOnlyList<TAbstract>coverage for the fail-closed default and every supported trust route, including typed and string allow-list configuration, assembly trust, custom filters, and the broad opt-out. It also updates diagnostics and public API documentation to point to the typed helpers, explain filter precedence, distinguish serializer support from type authorization, and warn about the security implications of allowing all resolvable types.The fail-closed default is preserved. Narrow type or assembly trust remains the recommended configuration.
