Delegated Types (Recording/Recordable Pattern)

A container model (Recording) unifies many content types (Recordables) that share metadata, access control, and operations.

Core insight: When many content types must comingle and share behavior, create a unified container rather than duplicating metadata or using complex polymorphic queries.

When to Use

digraph decision {
    "How many content types?" [shape=diamond];
    "Do they comingle in UI?" [shape=diamond];
    "Share metadata/operations?" [shape=diamond];
    "Direct associations" [shape=box];
    "Delegated types" [shape=box];
    "Consider merging types" [shape=box];
