SIE.5:9 - Consequences
The package can join warranted identities without losing source trace and can stop only the branches that depend on unresolved identity. Corrective source or steward decisions can be replayed against explicit consumers. The method also reveals when the useful relation is part, version, membership, or event participation rather than identity.
The cost is domain evidence and authority work. Some convenient global keys remain technical indexes rather than semantic truths, and some desired traces return incomplete.
