DI architecture for Bounded Contexts (Localized DI containers).

In Domain-Driven Design (DDD), different bounded contexts should not share the same DI container state or dependencies.

If you have a monolith containing a 'Billing' context and an 'Inventory' context, they should operate completely independently. Architectural purity involves creating independent DI containers (or modules) for each context. They communicate via events, preventing 'Inventory' from accidentally injecting the 'BillingDatabase' directly.
