test_messageVectorRegistrations

Verify ordinary message wiring and pointer-vector ownership across imports.

test_messageVectorRegistrations.test_message_iterator_owner_survives_late_import(late_module, operation)

Late imports preserve iterator ownership, redirection, and deletion checks.

test_messageVectorRegistrations.test_shared_message_vectors_preserve_wiring(vizard_first, message_type, field)

Temporary nested views accept wiring and raw pointer copies remain unowned.
