Constructive Blueprints

Declarative schema provisioning — define complete domain schemas as portable JSONB documents that compile into PostgreSQL tables, relations, security policies, and modules.

When to Apply

Use this skill when:

• Defining a blueprint (tables, fields, relations, policies, entity types)
• Working with blueprint templates and the template marketplace
• Choosing a current backend module preset (auth:hardened, b2b:storage, or full)
• Understanding Merkle-style definition hashing for deduplication and provenance
• Using construct_blueprint() or copy_template_to_blueprint()

Core Concepts

Two-Layer Model

• blueprint_template — shareable marketplace recipe. Immutable definition + metadata.
• blueprint — owned, executable instance scoped to a database. Created from a template via copy_template_to_blueprint() or authored directly.
