Key Features

• 176+ protocol interfaces: Runtime-checkable protocols for all ONEX service boundaries
• 22 domains: Event bus, handlers, nodes, registry, storage, and more
• Zero implementations: Protocols only -- concrete implementations live in omnibase_infra
• Structural typing: All protocols use @runtime_checkable for duck typing
• Contract-first: Protocols define the contract, implementations fulfill it
