This post explains why default parameter expressions are nonisolated and how to fix the pattern by moving defaults into the initializer body.

During test teardown we hit a repeatable 'pointer being freed was not allocated' crash while deallocating a @MainActor ObservableObject, and this post explains why we treated it as a Swift runtime edge case instead of rewriting our architecture.
