Dependency direction

Arrows mean “depends on.” Dependency direction always points toward the more stable, generic center:

1. wallets, identity products, and chain families select SDK components;
2. protocol/domain components select primitive foundations;
3. identus-crypto depends on identus-core;
4. identus-core and identus-crypto use identus-derive at compile time.

The reverse direction is forbidden. In particular, the three-crate release train cannot depend on Midnight, Compact, Cardano/PRISM, consumer repositories, wallet storage implementations, or product trust/custody policy.

This allows downstreams to evolve independently while sharing evidence-backed foundations.
