Custom Entities & Dynamic Entity Provisioning

Constructive has a hierarchical entity type system. Every scope of membership — app, org, channel, department, team, data room — is a membership type with its own entity table, permissions, memberships, and security policies.

Types 1 (app) and 2 (org) are built-in. Types 3+ are dynamic — you define them at runtime via the ORM, CLI, or blueprint definitions.
