# 🟡 Intermediate

**Connection: module registration, configuration, dynamic linking, and late binding.**

This level builds on Beginner addressing and ownership. Give independent parts
of an application their own configuration and scopes, then connect them through
explicit public operations.

## What you will learn

- Fluent registration with `SpellBinder` and module registration with `scan_bind`.
- Constructor, explicit, and collection dependency injection.
- Configuration, bind lifecycle hooks, runtime hooks, spell spaces, and lineage lifetimes.
- Dynamic posture, links, permissions, and ownership.
- Late binding with `SpellContract` and connected-subsystem composition.
- Early object disposal with `purge`, scoped cleanup, transfer, and severing relationships.
- Managed spell pools: lease, release and reset pooled objects in elastic, limited and queue modes.
- Named lesser scopes: Cloud lookup, creation-only names, collisions and retirement before pool reuse.
